"ern • �r —err GREELEY/WELD March 31, 1993 Ms. Connie Harbert Chairperson Weld County Commissioners Centennial Building 915 10th Street Greeley,CO 80631 Dear Ms. Harbert, The availability of a regional state-of-the-art solid waste management facility is important to the retention and attraction of industry to Weld County. At a recent meeting of the Executive Committee of the Greeley/Weld Economic Development Action Partnership (EDAP), we reaffirmed the above statement and endorsed the process of re-permitting the Central Weld Sanitary Landfill. We encourage the Weld County Commissioners to favorably consider the re-permitting of the subject facility.

Sfcr �uc5 March 31, 1993 Weld County Commissioners Connie Harbert Centennial Center 915 10th Street Greeley, CO. 80631 Dear Mrs. Harbert, I would like to point out at least one totally inaccurate statement in C-COW's flyer distributed in the area last Sunday soliciting support to close the landfill near our farm. In the third paragraph, second sentence it states that local farmers agreed to the siting of the dump. C-COW knows this is an untruth! Local farmers never agreed nor had any say except to object to the landfill. C-COW knows this. Our concern is the degree of dis-information they are distributing to yourselves and the community. This does give rise to what appears to be a credibility gap on the part of C- COW's position in this matter.

March 29, 1993 • 200 Oakridge Trail Kennedale, TX 76060 Weld County/Board of County Commissioners Centennial Center 915 10th Street Greeley, CO 80631 Dear Commissioners: This letter is in reference to my position on the disposition of Central Weld County landfill. I feel justified in expressing my position for the landfill's continued operation due to my strong ties to the area, and the four generations of my family that have called the Spomer farm home. This property is immediately adjacent to the landfill. Unlike many of the activist campaigning to close the landfill whose experience with the facility spans weeks or even months, I and my family have lived in intimate contact with the landfill from its inception approximately 21 years ago. The recent change in the landfill management to Waste Management Inc. should be viewed as a very positive event for Weld County and the landfill by all parties. My personal experience with Waste Management at the local government level have shown the company to be extremely professional in dealing with the environmental, technical and public issues associated with the management and disposal of solid waste. Waste Management has recently been awarded the local garbage hauling contract, have completed fabricating a recycling center for curbside programs and have provided a significant contribution towards public education in this area. The presence of a landfill in close proximity to one's home is never a positive thing. However, separating the emotional from the factual issues is essential when making decisions effecting the future of this and similar landfills. Rational, responsible citizens must acknowledge that: • Landfills are a fact of life. • No one wants a landfill close to their home. • Properly managed landfills provide the most economical solution to our solid waste disposal needs. • Locating landfills as close to the waste source reduces cost (transportation, labor and road maintenance) • The Central Weld County landfill is currently in operation, continued operation will not create a new monetary hardship on area properties (property values will not be affected). • Ground water pollution associated with the landfill will not disappear if the landfill were closed. xhel�i f KK 9'lOG <d . /�z_ zt,1< 2 Svcs • Waste Management Inc. has the expertise and resources not only to control future pollution, but to improve the environmental damage leftover from previous landfill operators. I have confidence that sound judgement will prevail when you, the Commissioners of Weld County must differentiate between reality and fantasy, and facts and emotions and that the taxpayers of Weld County will be provided the opportunity to enjoy the advantages of a professionally operated, economical source for solid waste disposal.

(Golder) to characterize the site hydrogeologic, geochemical and geotechnical conditions present at the Central Weld Sanitary Landfill. The objective of the investigation was to characterize the site conditions to a degree sufficient to allow development of a site hydrogeologic conceptual model. The conceptual hydrogeologic model will be used to design environmental monitoring systems for groundwater, surface water, and landfill gas. 1.2 Background Waste Services Corporation (WSC), an affiliate of Waste Management of Colorado, Inc. (WMC), operates a 110-acre landfill known as the Central Weld Sanitary Landfill. The landfill currently accepts household, commercial and industrial solid waste. No hazardous or radioactive wastes are accepted by the facility. 1.3 Site Description The facility is located in the southwest corner of Section 32, T.56N., R.66W., approximately 5 miles southwest of Greeley, Colorado (Figure 1-1). The site is located within a region of gently rolling topography. Elevations of the undisturbed portions of the site range from 4750 feet to 4840 feet (National Geodetic Survey Datum of 1929). The Big Thompson River lies approximately one-half mile south of the site as shown on Figure 1-2. The confluence of the Big Thompson River and the South Platte River is situated approximately two miles east of the site. A series of manmade ponds, referred to as Spomer Lakes, are present outside the western edge of the site. A diversion ditch extends along the Golder Associates 321061 July 1992 -2- 913-2403 northern and eastern boundaries of the site to channel shallow groundwater around the landfill. Flow in the diversion trench is directed either west and south into the Spomer Lakes drainage or east and south into an on-site retention pond. The northeastern and eastern portion of the diversion trench are underlain by a french drain system. The french drain is generally about nine feet below the elevation of the trench and was installed to maintain water levels beneath the landfill. Additional groundwater flow is directed into Spomer Lakes via a landfill underdrain installed in 1982 to control water levels under the landfill. The underdrain runs north-south under the western portion of the landfill and discharges into one of the Spomer Lakes. Figure 1-3 illustrates the diversion ditch, Spomer Lakes, retention pond, underdrain, and other on-site facilities. No airports are within 10,000 feet of the site (USDOT-FAA, verbal communication, 1992). 1.3.1 Natural and Geologic Hazards The site is not located within a 100-year floodplain. According to the Federal Emergency Management Agency (FEMA), the site is classified as Zone C, subject to minimal flooding (FEMA Map # 080266-0750C, 1982). The EPA has defined a seismic impact zone as "an area with a 10% or greater probability that the maximum horizontal acceleration in lithified earth material, expressed as a percentage of the earth's gravitational pull,...will exceed 0.10g in 250 years". The nearest potentially active faults are the Rocky Mountain Arsenal Fault and the Valmont Fault which are located approximately twenty-seven miles to the south (Kirkham and Rogers, 1981). The large distance to an active fault zone indicates that seismic impacts are unlikely to be significant at the landfill. The lack of significant potential seismic impacts at the site is substantiated by work conducted by Algermissen, et al, (1982), who determined that the site does not meet the criteria for a seismic Golder Associates 9 21.0'61 July 1992 -3- 913-2403 impact zone. Algermissen, et al, determined that the site has a 10% probability that the maximum horizontal acceleration in lithified material will exceed 0.08g in 250 years (Figure 1). The nearest underground coal mine is approximately one mile south of the site (Amuedo and Ivey, 1975), which suggests that subsidence due to mining activities is not significant at the landfill. The area surrounding the landfill is composed of low, rolling hills. The potential for landslides in the undisturbed areas is considered to be minimal. 1.3.2 Climate Local climatic conditions in the vicinity of the site are monitored by a weather station in Greeley. The site is characterized by semiarid conditions on the Colorado Piedmont section of the Great Plains Physiographic Province (Hansen, 1978). Based on the 84-year record at the Greeley weather station, Hansen (1978) reports that the temperature varies between a January mean of 24.7° F and a July mean of 72.3° F. The lowest recorded temperature was -45° F and the highest recorded temperature was 107° F. The mean annual precipitation for the area is 11.1 inches, with a recorded minimum of 5.4 inches and a maximum of 20.9 inches. Mean precipitation for the months of April through September is 8.9 inches. The maximum recorded 24-hour precipitation event is 3.4 inches. The mean annual relative humidity is 50%-55%, and the mean annual evaporation rate is 70-80 inches. The prevailing wind direction is toward the east. :A' St Golder Associates July 1992 -4- 913-2403 1.3.3 Population The geographical area surrounding the Central Weld County Landfill is primarily unincorporated and rural and is included in the Weld County Johnstown-Milliken Division. Census data for the unincorporated rural area is not directly available. However, an estimate for the unincorporated area can be obtained by subtracting incorporated populations from the population of the entire Weld County Johnstown-Milliken Division. Population figures for the division are available from the 1980 and 1990 census. The division as a whole increased in population 2.09%, from 7025 to 7172 during this period. Net unincorporated area population declined from 3628 in 1980 to 3396 in 1990, a 6.39% decrease. Table 1-1 details census data for the Johnstown-Milliken Division. 1.3.4 Permitted Water We11g Figure 1-5 illustrates the location of permitted water wells within a one mile radius of the landfill. As shown on Figure 1-5, a total of 20 wells are permitted by the Colorado State Engineer to withdraw water within a one mile radius of the landfill. These wells are generally permitted for domestic or irrigation use. Based on the topography of the area and proximity of the Big Thompson River south of the site, it is anticipated that shallow groundwater flow is towards the south and southeast. Three permitted wells are located south and southeast of the landfill between the landfill and the Big Thompson River. The closest of these wells is approximately 2000 feet from the landfill. As shown on Table 1-2, two of the three wells are reported to be completed at shallow depths (i.e., less than 40 feet deep) and are permitted for domestic and stock use. Accordingly, these two wells represent potential receptor points for shallow groundwater which might be impacted by the landfill. Golder Associates 9:1061 July 1992 -5- 913-2403 Information contained in the State Engineer's files can occasionally be outdated. The Central Weld Water District and Little Thompson Water District were contacted to determine if a public water supply has been extended to the area south of the landfill. Based on information supplied by the water district personnel, a public water supply has not been extended to the area. An additional permitted well is located east of the landfill (Figure 1-5). The depth of this well has not been reported to the Colorado State Engineer. However, based on available information this well is not downgradient of the landfill. 1.3.5 Site History Landfill operations may have begun at the site as early as 1967. The original Certificate of Designation (CD) for the site was issued by Weld County to Earl Moffat on October 6, 1971. Browning Ferris Industries (BFI) operated the site until 1976; it is not known when operational responsibility was transferred from Mr. Moffat to BFI. Ralph and Barbara Roweder (Weld Landfill, Inc.) operated the site from 1976 until June of 1979, when interest in the property was sold to Mr. C. Lynn Keirnes, of Colorado Landfill, Inc. The site was subsequently owned and operated by Waste Services Inc. from December, 1985 until 1989 (under Lynn Keirnes). In 1989, Waste Services, Inc. became Waste Services Corp. (WSC) under Mr. Brad Keirnes. On July 12, 1991 WSC merged with Waste Management of Colorado, Inc. (WMC), an operating division of Waste Management of North America (WMNA). The facility is on the Comprehensive Environmental Response, Compensation, and Liability Information System(CERCLIS) list due to alleged disposal of pesticide and radioactive waste during the period 1973 to 1976. Placement on this list indicates that the site is under investigation for inclusion on the Comprehensive Environmental Response, Compensation, and Liability Act(CERCLA) National Priority List(NPL). A preliminary acre sment of the site was conducted in 1987 by the Colorado Department of Health (CDH). Through review of Weld County Health Department records and an on-site investigation, the CDH found no groundwater, surface water, or air contamination. Golder Associates 9,:331.O6' July 1992 -6- 913-2403 The site currently accepts only solid waste and special wastes including petroleum contaminated soils and non-friable asbestos. Liquid sludges and hazardous wastes are not accepted. The two primary areas yet to be landfilled include the northeastern and southeastern portions of the site. A residence is located in the eastern portion of the site. The residence must be removed prior to landfilling in this area. 1.4 Previous Investigations Previous investigations at the site include: ► Warzyn Engineering Inc., 1984,"Hydrogeologic Assessment, Greeley Landfill, Weld County, Colorado." ► Industrial Compliance, 1991, "Ground-Water Investigation, Waste Services Corporation, Central Weld Sanitary Landfill." The Warzyn, 1984, report was based on a field investigation program which consisted of installing five shallow groundwater monitoring wells(GWMW-1 through GWMW-5),conducting in-situ permeability tests, and water quality (groundwater and surface water) sampling. The geology, hydrogeology, and water quality of the site were evaluated in this report. The Industrial Compliance, 1991, report involved characterizing the site for the potential of leachate and methane generation. In addition, an evaluation of the conceptual design of a diversion ditch was presented. The field investigation involved the installation of seven trash piezometers (TP-1 through TP-7) and installation of piezometers (P-1 through P-10). The locations of previous data collection points are presented on Figure 1-6. The trash piezometers remain active monitoring points and were utilized during this investigation. Eight of the 10 piezometers installed by Industrial Compliance were decommissioned during construction of the diversion trench. Piezometers P-1 and P-2 remain active and are included in this report. Golder Associates 9-1.061 July 1992 -7- 913-2403 1.5 Report Organization The following sections present a detailed summary of the Golder investigation. Section 2 discusses the field investigative program. Sections 3 and 4, respectively, summarize the geology and hydrogeology of the site. Section 5 presents the results of laboratory soils testing conducted to characterize the physical and mechanical properties of the geologic materials. Results of water quality sampling are discussed in Section 6. Validation of the analytical laboratory water quality results are summarized in Section 7. A summary and conclusions section is included as Section 8. Recommendations are made in Section 9. References are presented in Section 10. 32,1061 Golder Associates July 1992 -8- 913-2403 2.0 FIELD INVESTIGATION PROGRAM Based on the data collected by Warzyn and Industrial Compliance, additional field investigative activities were conducted. The field investigative program was designed to provide supplemental geologic, hydrogeologic, and geochemical conditions at the site. These data were obtained through installation of additional monitoring points, in-situ hydraulic testing, and water quality sampling. Each of these field activities is discussed in the following sections. Between February 13 and March 27, 1992 drilling and soil sampling were conducted as the first phase of the Golder hydrogeologic and geotechnical study for the site, in accordance with the "Hydrogeologic and Geotechnical Characterization Work Plan for the Central Weld Sanitary Landfill, Weld County, Colorado" (Golder, 1992). Geotechnical and geologic logging and soil sampling were conducted on all boreholes drilled during this field program. Seven geotechnical borings, designated as GT-1 through GT-7, were drilled for the purpose of soil sampling and site characterization. Monitoring wells were installed in three "shallow" boreholes, designated as GWMW-5N, GWMW-6 and GWMW-7, and seven "deep" boreholes, designated as GWMW- 8 through GWMW-14. Monitoring wells were installed to provide supplemental information regarding shallow groundwater and to define hydrogeologic conditions at greater depths than had previously been investigated. In addition, 21 boreholes were drilled in order to install soil gas probes to monitor water levels and landfill gas concentrations. Soil gas probes were designated as SG-1 through SG-10 and SG-12 through SG-21. Borehole SG-11 was drilled; however, a soil gas probe was not installed in this hole. See Section 2.1.3 for further discussion. As the drilling program progressed, well development, groundwater sampling, and surface water sampling were initiated. Slug testing was performed on all groundwater monitoring wells at the site, including previously installed wells, in order to obtain estimates of in-situ hydraulic conductivities. Laboratory testing of soil and rock samples was initiated soon after the first samples were collected to characterize the physical and mechanical properties of the geologic materials at the site. Golder Associates 9:1061. July 1992 -9- 913-2403 2.1 Drilling and Soil Sampling Drilling Engineers of Fort Collins, Colorado conducted the drilling and soil/rock sampling activities at the site under the supervision of Golder engineers and geologists. A Central Mine Equipment (CME) 55 drilling rig was used for all drilling at the site. Soil sampling was accomplished by using either an 18-inch long split spoon or a 5-foot long CME continuous sample barrel. Rock coring for the deep groundwater monitoring wells was conducted by air rotary methods. A Grimmer-Schmidt, 800 cubic feet per minute (CFM) output air compressor was used to supply down-hole air for rock coring. The air compressor was equipped with an internal filter as well as an in-line filter. No water was injected during rock coring operations. A summary of all geotechnical borings, monitoring wells and soil gas probe installations appears in Table 2-1. Figure 2-1 is a site map showing location of all borings, groundwater monitoring well installations and soil gas probes. 2.1.1 Geotechnical Borings Seven geotechnical borings (GT-1 through GT-7) were drilled in order to characterize geologic materials, particularly the fine-grained materials, near the ground surface in areas not yet landfilled. The locations of the geotechnical borings are shown on Figure 2-1. Geotechnical borings were advanced through surficial soil material and into underlying bedrock. Depths of geotechnical borings ranged from 23 to 30 feet below ground surface. The boreholes were drilled using 3.25-inch inside diameter (ID) hollow-stem augers. Soil sampling was accomplished using a 5-foot long, CME continuous sample barrel. Continuous sampling allows for complete profiling of the borehole. Data included in the geotechnical boring logs (Appendix A) include surveyed locations, ground surface elevations, drilling dates, soil and rock descriptions, sampling methods, recoveries and depth to groundwater. All geologic material retrieved during sampling was preserved in polyethylene bags for possible laboratory analyses at the Golder soils laboratory in Denver, Colorado. After drilling, the boreholes were grouted to ground surface using a cement/bentonite grout. Since borehole integrity was good and the boreholes were shallow, a tremie pipe was not necessary for grouting. 9.:1061 Golder Associates July 1992 -10- 913-2403 2.1.2 Groundwater Monitoring Well Boringj Ten boreholes were drilled to allow installation of groundwater monitoring wells (GWMW-6 through GWMW-14, and GWMW-5N) and to characterize geologic materials. GWMW-8 through GWMW-12 are deep wells which were sited adjacent to pre-existing shallow wells (GWMW-1 through GWMW-5) for the purpose of assessing deeper geologic and hydrologic systems at this site. Two shallow/deep well pairs GWMW-6/GWMW-13, and GWMW-7/GWMW-14 were sited in the southwestern portion of the site where coverage from the previous groundwater monitoring program was deemed inadequate. The locations of the monitoring wells are shown on Figure 2-1. Appendix B contains borehole logs for GWMW-5N through GWMW-14. Shallow boreholes GWMW-6 and GWMW-7 were drilled with 3.25-inch ID hollow-stem augers. Split spoon samples were taken at 5-foot intervals, starting at a depth of 4 feet below ground surface. Adjacent deep boreholes GWMW-13 and GWMW-14 were drilled with 3.25-inch ID hollow-stem augers to a depth corresponding to 15 feet below the base of the adjacent shallow well then were advanced to the total depth by rock coring. Because of the close proximity of the deep boreholes to the previously drilled shallow boreholes, the deep boreholes were sampled only at depths below the base of the adjacent shallow borehole. Shallow borehole GWMW-5N was also drilled with 3.25-inch ID hollow stem augers. Soil samples were not collected from this borehole, since it was drilled adjacent to borehole GWMW- 12 (Figure 2-1). Continuous soil sampling was conducted during drilling of GWMW-12. Prior to advancement by rock coring, deep boreholes GWMW-9, GWMW-11 and GWMW-12 were drilled with 3.25-inch hollow-stem augers and sampled at 5-foot intervals using split spoons to a depth corresponding to 15 feet below the total depth of the adjacent, pre-existing wells. Prior to rock coring to total depth, deep boreholes GWMW-8 and GWMW-10 were augured to a grey, silty fine sandstone contact, which had been identified in the previously drilled deep boreholes (GWMW-9, GWMW-11, GWMW-13, and GWMW-14). Total depth of the deep 931061 Golder Associates July 1992 -11- 913-2403 boreholes was designed to allow for completion of the screened intervals within the grey, silty fine sandstone which was used as a marker bed. Permanent new steel casings (6-inch ID with welded-in-place joints) were installed in all of the deep GWMW boreholes from 1-foot below ground surface to 15 feet below the base of the adjacent shallow well. The exception was GWMW-11 in which the steel casing was advanced to 25 feet below the base of the adjacent well (GWMW-4) since material above that depth was not competent enough to hold the permanent steel casing in place. In all deep boreholes (GWMW-8 through GWMW-12) the annulus between the steel casing and the borehole was grouted with a cement/bentonite mixture and allowed to set-up for approximately 24 hours before rock coring began. An NX-size borehole was then advanced by air-rotary methods to a depth corresponding to 15 feet below the top of the grey, silty fine sandstone. Once the total depth was reached by rock coring methods, a tri-cone bit was used to increase the diameter of the borehole to 8 inches in preparation for installation of the monitoring well. All down-hole equipment was steam-cleaned with a high temperature, high pressure sprayer between boreholes. Soil retrieved from split spoon sampling was preserved in polyethylene bags for possible laboratory analysis. Rock core which was not preserved for laboratory analysis was placed in cardboard core boxes. Rock core which was chosen for laboratory analysis was preserved in the manner described below. The rock core sample field preservation technique included wrapping the sample in a layer of plastic followed by a layer of aluminum foil and a sample identification label. The sample was then dipped in melted wax. The wax was allowed to harden and the sample was placed in a polyethylene bag. Preserved rock samples were placed in PVC tubes for transport to the Golder soils laboratory in Denver, Colorado. 9:1.061 Golder Associates July 1992 -12- 913-2403 2.1.3 Soil Gas Probe Borings Twenty-one borings for soil gas probes designated as SG-1 through SG-21 were drilled at the site (Figure 2-1). Soil gas probe SG-11 will be installed during future site activities. The borings were generally spaced approximately 500 feet apart along the perimeter of the site. In addition, one boring (SG-10) was sited near the gate house, one boring (SG-14) was sited near the residence and one boring (SG-15) was sited near the machine shop. These three borings were situated between their respective buildings and landfilled areas in order to detect the potential occurrence of landfill gas. Soil gas probe borings were drilled with hollow-stem augers (either 3.25-inch or 4.25-inch ID) and sampled with a 5-foot long, CME continuous sample barrel. All soil and rock samples were preserved in polyethylene bags for possible laboratory analysis at the Golder soils laboratory in Denver, Colorado. Logs for the soil gas probe boreholes are presented in Appendix C. 2.2 Monitoring Well Installation Procedures Ten monitoring wells were installed as part of the hydrogeologic characterization, the locations of which are shown on Figure 2-1. Two monitoring wells (GWMW-6 and GWMW-7) were installed to characterize the shallow groundwater system in areas where data collection points were absent. Seven monitoring wells (GWMW-8 through GWMW-14)were installed to monitor a deeper groundwater system. One shallow monitoring well (GWMW-5N) was installed to replace GWMW-5 which is located outside of the site property boundary. Monitoring wells were installed into the borings described in Section 2.1.2. Figures 2-2 and 2-3 illustrate typical construction details for the shallow and deep monitoring wells, respectively. Monitoring well construction summaries are presented in Appendix D. Stratigraphic descriptions are shown on each monitoring well construction summary. Shallow monitoring wells were completed within the hollow-stem augers. Deep monitoring wells were completed within the permanent steel casing (as described in Section 2.1.2) and below that depth in the open borehole. Golder Associates 331061 July 1992 -13- 913-2403 Centralizers were installed in the deep groundwater monitoring wells (GWMW-8 through GWMW-14) since the wells were constructed in open boreholes. All monitoring wells were constructed with 2-inch, flush-threaded Schedule-40 PVC. All pipe joints were fitted with 0- rings and were further sealed with teflon tape. Flush-threaded end caps, approximately 2-inches long, were attached to the base of each screen to reduce the possibility of sediment migration into the monitoring wells. A PVC slip cap was placed over the top of the riser. After installation of the PVC screen and riser pipe into the hole, a primary filter pack, consisting of medium-grained sand (10/20 silica sand) was placed into the annular space surrounding the PVC. The filter pack generally extended at least 3 feet above the top of the screened interval. During construction of the shallow wells, the hollow-stem augers were slowly withdrawn and the rate of sand flow into the borehole was restricted to allow for settlement. Hollow-stem augers did not remain in the deep wells during construction; however, the rate of flow of the filter sand into the borehole was sufficiently restricted to allow for proper settlement and reduce the potential for bridging. Following filter pack placement, a minimum of 3 feet of bentonite chips was placed in the borehole annulus above the filter pack to seal off the screened interval from the overlying geologic materials. A cement/bentonite grout slurry composed of eight parts Portland cement one part to bentonite powder was placed above the bentonite seal to a depth of approximately 3 feet below ground surface to prevent downward migration of infiltrated water through the borehole. Monitoring well construction was completed by installing a 6-inch square by 7-feet long, locking anodized aluminum protective cover over the PVC riser. The protective cover was set in approximately 2-feet of concrete to reduce the potential for infiltration of surface water and to provide a firm foundation for the protective casing. The annular space between the protective cover and the riser was filled with bentonite chips to ground surface, above which 1/4-inch pea gravel was placed to within 6-inches of the top of the riser. Weep holes were drilled in the Golder Associates 921.061 July 1992 -14- 913-2403 protective covers approximately 6-inches above ground surface to provide an outlet for any water that might be introduced inside the protective cover. The northing and easting coordinates, ground surface elevations and top of PVC riser elevations were determined by Stewart and Associates, a local surveying firm. All down-hole equipment such as hollow-stem augers, center plugs, center rods and sampling devices were steam-cleaned before the first borehole was drilled and between each boring. All monitoring well screens and riser pipe were supplied by Johnson Filtration Systems, were factory cleaned, and were transported to the site wrapped in clean plastic. The use of factory cleaned and wrapped PVC eliminated the need for steam-cleaning prior to installation. 2.3 Landfill Soil Gas Probe Installation Procedures Twenty landfill soil gas probes, designated SG-1 through SG-10 and SG-12 through SG-21 were installed as part of the site characterization. Soil gas probe SG-11 will be installed during future site activities. Depths of the soil gas probes ranged from 8 to 46 feet below ground surface. The locations of the soil gas probes are shown on Figure 2-1. Seventeen soil gas probe locations were sited at approximately 500 foot centers around the perimeter of the site. An additional three soil gas probes were sited near landfill buildings. Downhole equipment was decontaminated by steam-cleaning prior to drilling the soil gas probe boreholes. Since the soil gas probes are not designed for use as groundwater monitoring points, decontamination between boreholes was not conducted. Figure 2-4 presents a typical soil gas probe construction detail. The soil gas probes were constructed within the hollow-stem augers when borehole integrity was questionable. However, the majority of the boreholes were relatively shallow and were sufficiently stable to allow construction in the open borehole. Filter pack for the soil gas probes consists of 1/4" diameter pea gravel. Therefore open borehole construction was preferable because the large diameter of the filter pack presented a high potential for bridging between the interior of the augers and the casing. Open borehole construction provided a larger annulus Golder Associates 9:1.061 July 1992 -15- 913-2403 between the casing and the borehole, which decreased the probability of bridging of the filter pack. All soil gas probes were constructed with 1-inch diameter, Schedule 40 PVC. Soil gas screens consist of either 5-feet or 10-feet sections of 0.010-inch factory slotted Schedule 40 PVC. Slip caps, approximately 1-inch in length, were attached to the base of the screened section. Slip caps fitted with quick-connect valves were attached to the top of the riser section to provide soil gas monitoring points. Soil gas probe boreholes were extended below the water table or below the inferred base of solid waste, whichever occurred first. The screened intervals for the soil gas probes generally extend from 2 feet above the base of the boring to 6 feet below ground surface. In one instance (SG-5) groundwater was present less than 6 feet below the surface. The top of the screened interval for SG-5 was placed closer to the ground surface to maximize efficiency of this soil gas probe. Soil gas probe filter pack consists of 1/4-inch diameter pea gravel and generally extends from 2 feet below the base of the screened interval to 2 feet above the screened interval. The pea gravel layer is generally overlain by a 1-foot thick layer of 16/40 silica sand. Filter sand was not placed in soil gas probes SG-5 and SG-9 because of their shallow completion depths. A bentonite seal consisting of a 1-foot thick layer of bentonite chips generally extends to within 2- feet below the ground surface. Soil gas probe construction was completed by installing a 6-inch square by 5-feet long, locking anodized aluminum protective cover over the PVC riser. The protective cover was set in approximately 2-feet of concrete. The annular space between the protective cover and the riser was filled with bentonite chips to ground surface, above which 1/4-inch pea gravel was placed to within 6-inches of the top of the riser. Weep holes were drilled in the protective covers approximately 6-inches above ground surface to provide an outlet for any water that might be introduced inside the protective cover. The northing and Basting coordinates, ground surface elevations and top of PVC riser elevations were determined by Stewart and Associates, a local surveying firm. Landfill soil gas probe construction summaries are presented in Appendix D. Golder Associates 921.061 l July 1992 -16- 913-2403 2.4 Groundwater Monitoring Well Development During the period from March 17 through March 23, 1992, Golder engineering technicians conducted groundwater monitoring well development for all wells installed as part of the field activities (i.e., GWMW-5N through GWMW-14). The groundwater monitoring wells were developed in order to remove sediment and water associated with installation and to ensure effective hydraulic communication with the geologic formation. With the exception of monitoring well GWMW-5N, well development was accomplished by using a Hydrostar sand pump. The pump was not in contact with groundwater. All downhole pipe which did contact groundwater was steam-cleaned prior to development of each well. The pump was driven by a portable air compressor equipped with an inline oil and water filter, thus reducing the risk of contamination. Each well except GWMW-5N was developed by pumping for a minimum of four hours. Monitoring well GWMW-5N was developed by hand-bailing for eight hours. During the development process, pH and conductivity of discharge water were monitored for stability. Details concerning well development are included in the Monitoring Well Construction Summaries which are presented in Appendix E. 2.5 In-Situ Hydraulic Testing 2.5.1 Methodology In-situ hydraulic testing was conducted by Golder hydrogeologists and engineering technicians on April 6 and 7, 1992. All groundwater monitoring wells were tested including those previously installed (GWMW-1 through GWMW-5) and those installed by Golder (GWMW-5N through GWMW-14). Data collected during well development and groundwater sampling indicated that rising head slug tests would provide the most effective means of estimating near- •T:10 61 Golder Associates July 1992 -17- 913-2403 borehole hydraulic properties at the site. Therefore, in-situ permeability testing consisted of rising head slug tests. A rising head slug test involves the removal of a small volume of water (or slug) from the well and then monitoring the recovery over time. Recovery data as a function of time were used to estimate hydraulic conductivities by the Hvorslev (1951) method. The Hvorslev slug test rising head solution, suitable for wells over short intervals, is given as: 2m1, K-(d4)21n[ 8D)] where; K = hydraulic conductivity doff = effective diameter m = O Kv)�n ICN��= horizontal hydraulic conductivity K, = vertical hydraulic conductivity L = the screened interval (if the static water level is above the top of the screen); or, the difference between the static water level and the bottom of the screened interval (if the static water level is below the top of the screen) D = the borehole diameter T = elapsed time For this investigation, K, is assumed to be ten times higher than K,. Golder Associates 321061 July 1992 -18- 913-2403 2.5.2 Results of In-Situ Hydraulic Testing Estimates of hydraulic conductivities were obtained from in-situ hydraulic conductivity testing data by the Hvorslev method as illustrated in Section 2.5.1. To illustrate this method of analysis, a sample calculation using recovery data from GWMW-14 is presented below. The accompanying Hvorslev curve is presented in Figure H-15. d = 2 in = 0.17ft 'I 12 in/ft m=3.16 L=10.00ft D=0.688ft T=41.64min (0.17 fr)2ln[2(3.16)(10.00 ft)] K= 0.688 ft 8(10.00 fr)(41.64 min) K=1.99x10-s cm/sec The effective diameter dCR, was calculated using the borehole diameter, the riser pipe internal diameter and an assumed porosity of 0.30 for the filter pack. When drawdown occurs solely within the riser pipe the value for de is the diameter of the pipe. However, when drawdown takes place within the screened interval, the effective diameter is equal to the difference between the riser diameter and the annulus diameter multiplied by the assumed porosity of the filter pack, which is then added to the diameter of the riser pipe. Golder Associates 91.061 July 1992 -19- 913-2403 A summary of the estimated hydraulic conductivity for each of the wells is provided in Table 2-2. Included in Table 2-2 are values for geometric mean hydraulic conductivities for the shallow wells (GWMW-1 through GWMW-7) and for the deep wells (GWMW-8 through GWMW-14), as are the types of geologic materials tested. Since bedrock units at the site are typically fairly coarse-grained materials (silty sandstone and sandy siltstone), interlayered with fine-grained materials (claystone), the values for hydraulic conductivity estimated by in-situ hydraulic testing likely represent horizontal permeabilities of the coarse-grained materials. 2.6 Water Ouality Sampling 2.6.1 Groundwater Monitoring Well Sampling Monitoring wells GWMW-1 through GWMW-14 were sampled in order to provide groundwater quality information for the site. Groundwater samples were collected by a Golder engineering technician between March 25 and March 31, 1992. Groundwater analyses were performed by Enseco Rocky Mountain Analytical Laboratory of Wheat Ridge, Colorado. Groundwater samples were analyzed for concentration of the following parameters: ► Volatile organics; ► Pesticides (Endrin, Lindane, Methoxychlor and Toxaphene); ► Herbicides [2,4-D, 2,4,5-TI', (Silvex)]; ► Dissolved metals (arsenic, barium, cadmium, chromium, iron, lead, manganese, mercury, selenium and silver); ► Nutrients (Nitrate and Ammonia); ► Anion parameters (sulfate, bicarbonate, carbonate and chloride); ► Major cation parameters (magnesium, calcium, potassium and sodium); and, ► Radionuclides (gross alpha, gross beta, radium 226 and radium 228). 9:1.961 Golder Associates July 1992 -20- 913-2403 A discussion of water quality analytical results is presented in Section 6.0. Water levels were recorded for each monitoring well immediately prior to purging. Approximately three casing volumes of groundwater were purged from each monitoring well immediately prior to sample collection, providing that the well did not first bail dry. The monitoring wells were purged and sampled by using either a Hydrostar pump, stainless steel bailer or teflon bailer. Field parameters consisting of temperature, pH and specific conductance were recorded during the purging process to ensure that groundwater samples were representative of formation water. Field parameter measurements are presented on the groundwater monitoring well construction summaries included as Appendix E. The Hydrostar pump and downhole PVC sampling pipe were steam-cleaned before sampling and between each monitoring well using water from a WMC-approved, onsite source. The stainless steel bailer was decontaminated before any sampling took place and between sampling each monitoring well. The decontamination process consisted of first rinsing the equipment with a solution of phosphate-free Liquinox ' detergent and distilled water, which was followed by a methanol rinse, and completed with a triple distilled water rinse. New polypropylene rope was used for each well and discarded after use. A new pair of disposable, sanitized surgical gloves was worn by sampling personnel at each sampling point. The groundwater samples were collected from either the stainless steel bailer or the Hydrostar pump discharge tube. The groundwater samples were placed into clean plastic bottles and immediately transferred into the appropriate sample preservation containers provided by the laboratory. The exceptions to this procedure were samples intended for volatile organic analysis (VOA) which were placed directly into a VOA sample vial. Samples analyzed for major anions were collected in 32-ounce high density polyethylene bottles and did not require an added preservative. Samples analyzed for major cation parameters were collected in 16-ounce high density polyethylene bottles and contained an added preservative consisting of 10 milliliters of 20% nitric acid. VOA samples were collected in 40-milliliter glass VOA vials (3 per sampling point) which contained a hydrochloric acid preservative. Samples Golder Associates 9- .1.flfj July 1992 -21- 913-2403 intended for nitrate and ammonia analysis were collected in 16-ounce glass bottles and preserved with 2 milliliters of 50% nitric aci4. Samples intended for dissolved metals analysis were filtered through a 0.45-micron disposable filter prior to collection in a 16-ounce high density polyethylene bottle containing 10 milliliters of 20% nitric acid as a preservative, with the exception of a few samples in which the laboratory prepared preservative was added upon receipt by Enseco Rocky Mountain Laboratory. Samples analyzed for pesticides were collected in 1- liter glass bottles (2 per sampling point) with no preservative. Samples intended for herbicide analysis were collected in 1-liter glass bottles with no preservative. Samples analyzed for radionuclides were collected in 32-ounce high density polyethylene bottles (2 per sampling point) and preserved with 10 milliliters of 20% nitric acid. All sample containers were labeled with the sampling location, parameters to be analyzed, date and time sampled, preservative present, and signature of the sampling personnel. Samples were immediately placed in ice-filled coolers after collection and labelling. Table 2-3 presents a summary of containers, filtration and preservatives for the parameters analyzed. Sample integrity data sheets which provide sample collection data for each sampling location are presented in Appendix F. Chain of custody forms were completed by the sampling personnel and placed inside the coolers with the appropriate samples. The coolers were sealed with signed chain of custody seals and delivered, via courier, to the laboratory on a daily basis. A field blank sample was collected by pouring laboratory-supplied deionized water through the decontaminated bailer directly into sample collection bottles. This type of sample is generally referred to as an equipment blank or a field blank. The field blank was identified as "EB" during sampling and analysis and is identified as "FB" in the following sections and tables of this report. A laboratory prepared trip blank consisting of 1, 40-milliliter VOA vial was also provided for analysis and was identified as "TB". Duplicate samples were collected at monitoring well GWMW-5N. r 9,7:1T6 Golder Associates July 1992 -22- 913-2403 For additional QA/QC, laboratory blanks were prepared by Enseco Rocky Mountain Analytical Laboratory. Laboratory blanks consist of a barren solution, usually distilled water or another inert substance, which is prepared by the laboratory and treated as a sample for the parameter being analyzed. This includes all pretreatment, preparation, holding times and the actual analysis. 2.6.2 Surface Water Sampling Surface water samples were collected from the following three locations: ► The corrugated steel culvert which drains the off-site area at the north property boundary (designated as N-Discharge for sample identification): ► The outlet of the landfill underdrain near the southwestern property boundary (designated as LF-UD for sample identification); and, ► The discharge pipe located at the inlet of the retention pond which is northeast of the residence structure (designated as RP-Inlet for sample identification). The locations of the surface water sampling points are shown on Figure 2-1. Samples taken from the north discharge pipe and the landfill underdrain were collected directly from the pipe outlets. The discharge pipe at the retention pond inlet was submerged at the time of collection. Therefore, the samples were collected within the pond at a point approximately 10 feet downstream from the mouth of the pipe. Care was taken not to incorporate bottom sediments in the samples. All surface water samples were collected in clean plastic bottles and immediately transferred into the appropriate laboratory parameter bottles. Surface water samples were analyzed for the same parameters as were the groundwater samples. Surface water samples were analyzed for total metals (i.e., the samples were not field filtered). Sample preservation, chain of custody, and transport to Enseco Rocky Mountain Analytical Laboratory were accomplished in the same manner as discussed in Section 2.6.1. Sample 1' 6 Golder Associates r ( July 1992 -33- 913-2403 diversion trench, a claystone unit is present at a relatively shallow depth in this area. Groundwater was observed seeping into the trench from the soil/claystone contact. Evidently, the claystone unit in this area is acting as a bather to downward migration of water and is resulting in perched conditions east of the trench. The perched water is probably maintained at an artificially high level due to irrigation activities known to occur immediately north and east of the landfill. The irrigation activities likely provide increased recharge to the groundwater east of the trench. According to landfill employees, the water level east of the trench, as observed at the east wall of the trench, rises a few feet during the irrigation season. A similar rise is not observed along the western wall of the trench, since irrigation does not occur on the landfill. 4.3.3 Lower Weathered Bedrock Deep groundwater monitoring wells GWMW-8 through GWMW-14 were screened within the Lower Weathered Bedrock. Adjacent shallow wells screened within the Upper Weathered Bedrock indicate a saturated zone in the upper portion of the Upper Weathered Bedrock. The deep wells indicate a saturated zone within the upper portion of the Lower Weathered Bedrock. During drilling a relatively dry zone was noted within the Upper Weathered Bedrock. The presence of the dry material suggests that the degree of communication between the shallow and deep saturated zones is minimal. Figure 4-2 is a contour map of the deep groundwater potentiometric surface. Based on information presented in Figure 4-2, the direction of groundwater flow in that zone is towards the south-southeast The average horizontal groundwater gradient in the lower groundwater zone is approximately 0.02 ft/ft.. Assuming an effective porosity of 30% (Freeze and Cherry, 1979) and a hydraulic conductivity of 2.5x10'5 cm/sec (Section 5.1.1), the average horizontal groundwater flow velocity is calculated to be approximately 2 feet per year. &6T Golder Associates 921%%.'. 7 ( 1`� Mu Management of North America, inr:.

Sampling was conducted on July 15, 16, 17, 20 and 21, 1992 and the analysis was performed by the Waste Management, Inc. Environmental-Monitoring Laboratory (EML). 4Th. results presented in the EML ieport con-filth-the original results reported by Enseco-Rocky Mountain Analytical in support of the hydro-geo investigation. Virtually all volatile compounds detected during the original sampling and Enseco analysis were confirmed and reported by the/ EML analysis. f Compounds that were not confirmed by EML include acetone in GWMW02 which was detected just over the reporting by Enseco. EML reported no volatile compounds in GWMW02 indicating that the original value is most likely a laboratory or field contaminant. EML did not report methylene chloride in.GWMW07, again indicating that the Enseco value' nay be from a laboratory source. r The Enseco data reports the compound 1,2-dichloroethene as "total" and reported a detection of this compound in wells GWMW05 and GWMW5N. EML reports only the "trans" isomer and this was not detected in GWMW05 or GWMW5N indicating that the "total" values in the Enseco report are likely attributable to the "cis" isomer. `[n addition to confirming the'compounds detected in the original analysis, the EML data, which i generally had lower reporting limits for the volatile compounds reported additional compounds ,._., at--a level that was below the Enseco reporting limit.'

A separate Client Report will be generated for each one. It is the goal of WMI Environmental Monitoring Laboratories, Inc. to provide analytical data in a timely fashion, formatted in a way that our clients will find most useful. If you have any questions concerning the form or content of this report, please contact the WMI EML Customer Operations Department: Main Number (708 ) 208-3100 FAX Number (708) 208-1175 ` Note : Two designations may appear in the results column of your Client Report: NA or ND. The designation NA (for "Not Analyzed" ) is used to identify analytes which were requested in the monitoring program, but for which no suitable testing methodology exists. NA may also indicate a dry well, broken sample bottle, insufficient sample volume, or other condition which precludes analysis for a sample. The designation ND ( for "Not Detected" ) is used to indicate that the analyte of interest was not found at or above the concentration listed under the EMLRL (EML Reporting Limit) heading. Unless otherwise indicated, all analytes meet the requirements of holding time as specified in the method. ycd,c Bruce Warden Fra k Jark Assistant Director Mana• -r Laboratory Operations Qualit - -grams 931061 Data Qualifier Comment Code Definitions AR Acid surrogate recoveries did not meet the acceptance criteria of the method. Oxidation degradation due to sample matrix was confirmed. BB: Broken bottle. BL: The method blank concentration associated with this analyte did not meet the acceptance criteria of the method. CX: The concentration of this compound exceeded the calibration used for this analysis. The concentration reported is estimated. CU: Co-elution with another compound interferes with the quantitation of this compound. The concentration reported is estimated. DL: The sample was diluted during analysis. Reporting limits have been adjusted where necessary. DP: This -ample was analyzed in duplicate. The relative percent difference between the two results did not meet the acceptance criteria of the method. DW: Dry well HS: The headspace in this sample bottle exceeded 6 millimeters. IS: The internal standard recoveries associated with this analysis did not meet the acceptance criteria of the method. IV: The bottle did not contain enough sample to perform the analysis. MP: 3-methylhphenol and 4-methylphenol co-elute under the analytical conditions of the method, and can not be differentiated solely on the basis of their mass spectra. The concentrations reported may be either or both isomers. MX: This sample was used as a matrix spike. The percent recovery — did not meet the acceptance criteria of the method. The analysis of a quality control standard showed the analytical system was in control. The result reported may therefore be affected by matrix interferences. NN: N-nitrosodiphenylamine can not be distinguished from diphenylamine using gas chromatography. The concentrations reported may be either or both compounds. NQ: No standard qualifier code is in use for this qualification. See the associated comment. NS: There was not enough sample to repeat this analysis. 931061 PL: This result may be a product of contamination from phthalate plasticizers, which are a common lab contaminant. PX: This sample required preservation in the field to a pH of less than 2. The pH was checked after receipt at the lab, and did not . have a pH of less than 2. • PY: This sample required preservation in the field to a pH of 4 to 5. The pH was checked after receipt at the lab, and did not have a pH of 4 to 5. PZ: This sample required preservation in the field to a pH of 12 or greater. The pH was checked after receipt at the lab, and did not have a pH of 12 or greater. QX: This sample was used as a matrix spike. The percent recovery did not meet the acceptance criteria of the method. The analysis of a quality control standard showed the analytical system was out-of-control. The analytical result for this parameter in the unspiked sample is suspect and may not be reported for regulatory compliance purposes. RA Acid surrogate recoveries associated with this analysis did not meet the acceptance criteria of the method. BB: Base/neutral surrogate recoveries associated with this analysis did not meet the acceptance criteria of the method. SB: The analysis of this sample was performed by an approved subcontract laboratory. ST: This compound is not stable in acidic water. SU: The analysis of the surrogate with this sample did not meet the acceptance criteria of the method. TX: The analysis for this parameter was conducted after the holding time specified in the method. UN: - This compound is not stable under the conditions of the analysis. 931061 NMI ENVIRONMENTAL MONITORING LABORATORIES, INC Page: 1 ‘e CLIENT REPORT Site: 488 - Central Weld County Sample Point: LFUD ENS: 92-11934 Sampled: 16-JUL-1992 Sanitary Landfill Sample Type: RIV/STREAM MP: 488921 Received: 17-JUL-1992 Weld County Road 271/2 Sample Number: AF2942 REV: 00 Reported: 1-SEP-1992 Miliken CO 80543 Analyte Result OIL RL Units Comments Method FIELD DATA: PH FIELD 7.07 PH UNITS FDPHQUADO1 PH FIELD 7.00 PH UNITS FDPHQUADO1 PH FIELD 7.05 PH UNITS FDPHQUADO1 PH FIELD 7.02 PH UNITS FDPHQUADO1 SPECIFIC CONDUCTANCE FIELD 3760.

The results in the Client Report are for a single ENS (Event Notification System) number only. The sampling event at your facility may include multiple ENS numbers. A separate Client Report will be generated for each one. It is the goal of WMI Environmental Monitoring Laboratories, Inc. to provide analytical data in a timely fashion, formatted in a way that our clients will find most useful. If you have any questions concerning the form or content of this report, please contact the WMI EML Customer Operations Department: Main Number ( 708) 208-3100 FAX Number (708) 208-1175 Note: Two designations may appear in the results column of your Client Report: NA or ND. The designation NA ( for "Not Analyzed" ) is used to identify analytes which were requested in the monitoring program, but for which no suitable testing methodology exists . NA may also indicate a dry well, broken sample bottle, insufficient sample volume, or other condition which precludes analysis for a sample. The designation ND (for "Not Detected" ) is used to indicate that the analyte of interest was not found at or above the concentration listed under the EMLBL (EML Reporting Limit) heading. Unless otherwise indicated, all analytes meet the requirements of holding time as specified in the method. rgmAL--- Bruce Warden Fra k Jark- Assistant Director Mana- -r Laboratory Operations Qualit .grams 4 O 931061 `ie Data Qualifier Comment Code Definitions AR: Acid surrogate recoveries did not meet the acceptance criteria of the method. Oxidation degradation due to sample matrix was confirmed. BB: • Broken bottle. BL: The method blank concentration associated with this analyte did not meet the acceptance criteria of the method. C%: The concentration of this compound exceeded the calibration used for this analysis. The concentration reported is estimated. CU: Co-elution with another compound interferes with the quantitation of this compound. The concentration reported is estimated. DL: The sample was diluted during analysis. Reporting limits have been adjusted where necessary. DP: This sample was analyzed in duplicate. The relative percent difference between the two results did not meet the acceptance criteria of the method. DW: Dry well HS: The headspace in this sample bottle exceeded 6 millimeters. IS: The internal standard recoveries associated with this analysis did not meet the acceptance criteria of the method. IV: The bottle did not contain enough sample to perform the analysis. MP: 3-methylhphenol and 4-methylphenol co-elute under the analytical conditions of the method, and can not be differentiated solely on the basis of their mass spectra. The concentrations reported may be either or both isomers. M%: This sample was used as a matrix spike. The percent recovery did not meet the acceptance criteria of the method. The analysis of a quality control standard showed the analytical system was in control. The result reported may therefore be affected by matrix interferences. NN: N-nitrosodiphenylamine can not be distinguished from diphenylamine using gas chromatography. The concentrations reported may be either or both compounds. NQ: No standard qualifier code is in use for this qualification. See the associated comment. NS: There was not enough sample to repeat this analysis. 'C PL: This result may be a product of contamination from phthalate plasticizers, which are a common lab contaminant. P%: This sample required preservation in the field to a pH of less than 2. The pH was checked after receipt at the lab, and did not have a pH of less than 2. PY: This sample required preservation in the field to a pH of 4 to 5. The pH was checked after receipt at the lab, and did not have a pH of 4 to 5. PZ: This sample required preservation in the field to a pH of 12 or greater. The pH was checked after receipt at the lab, and did not have a pH of 12 or greater. Q%: This sample was used as a matrix spike. The percent recovery did not meet the acceptance criteria of the method. The analysis of a quality control standard showed the analytical system was out-of-control. The analytical result for this parameter in the unspiked sample is suspect and may not be reported for regulatory compliance purposes. RA: Acid surrogate recoveries associated with this analysis did not ` meet the acceptance criteria of the method. RB: Base/neutral surrogate recoveries associated with this analysis did not meet the acceptance criteria of the method. SB: The analysis of this sample was performed by an approved subcontract laboratory. ST: This compound is not stable in acidic water. SU: The analysis of the surrogate with this sample did not meet the acceptance criteria of the method. T%: The analysis for this parameter was conducted after the holding time specified in the method. UN: This compound is not stable under the conditions of the analysis. 931061 tlaS Page: 1 1 1!R 6NVIR0NlENTAL MONITORING LABORATORIES, INC ‘4! '4!'

Attention: Mr. Bill Hedberg RE: EXPANDED HYDROGEOLOGICAL INVESTIGATION AT THE CENTRAL WELD SANITARY LANDFILL, COLORADO • c�:r I Dear Bill: Golder Associates Inc. (Golder) is pleased to present the results of the above-referenced project to Waste Services Corporation (WSC). Golder has completed the installation of temporary sampling points (TSPs) and collected groundwater samples for chemical analysis. The following sections provide background information, summarize field activities, and present results of the analysis. fi 1.0 BACKGROUND Golder recently completed a hydrogeological and geotechnical investigation for the Central Weld Sanitary Landfill (CWSL) (see "Hydrogeologic and Geotechnical Characterization for the Central Weld Sanitary Landfill", Golder, 1992). Seven geotechnical borings, three shallow groundwater monitoring wells, seven deep groundwater monitoring wells, and twenty soil gas probes were installed during the field investigation portion of the investigation. The geotechnical borings, monitoring wells, and soil gas probes supplemented five shallow groundwater monitoring wells previously installed at the site. Water quality data were generated from samples collected from groundwater monitoring wells and surface water sampling points. Volatile organic compounds (VOCs) were detected in four shallow groundwater monitoring wells (GWMW-4, GWMW-5, GWMW-5N and GWMW-7) on the southern (downgradient) side of the landfill and at one surface water sampling point, the outlet of the landfill underdrain (LF-UD). Figure 1 shows the locations of sampling points where VOCs were detected and Table 1 �-` EXHIBIT s n OFFICES IN AUSTRALIA,CANADA,GERMANY,HUNGARY,ITALY,SWEDEN,UNITED KINCM fWi h/ s93, ETES ei October 23. 1992 -2- 913-2403 summarizes the results. It should be noted that VOCs were detected in GWMW-5, located off-site approximately 20 feet south of the site boundary. WSC determined that additional investigative efforts were required to further characterize the quality of shallow groundwater downgradient of the landfill. v .`* I 2.0 FIELD ACTIVITIES Field activities conducted at the CWSL as part of the expanded hydrogeologic investigation I included drilling, installation of TSPs and collection of groundwater samples from the TSPs. The field program was initiated on September 21, 1992. The following sections provide a brief description of drilling operations, TSP construction, and groundwater sampling 0 , procedures. .r 2.1 Drilling. Operations Drilling operations were conducted by GEO Environmental (GEO) of Golden, Colorado. I GEO utilized a pickup-truck mounted Giddings drill rig for all boreholes except TSP-5. Due to difficult access to the TSP-5 location, this borehole was drilled with a small all terrain vehicle mounted hydraulic hammer rig, utilizing a 1-inch diameter drill rod. Other boreholes were drilled with 2-inch diameter solid stem flight augers. Golder field personnel supervised II -, all drilling activities. Boreholes were drilled approximately five feet below the anticipated water table depth, based on previous site-characterization data. Auger refusal was I - encountered in TSP-7 and TSP-8 at depths approximately 10 feet below the anticipated water a...`��` table depth. No water was encountered at these locations. A summary of final borehole i. depths, including water levels encountered, is provided in Table 2. � .,,r r." All drilling and sampling equipment, including drill rods, samplers, and tools, was steam- ' cleaned prior to initiation of drilling activities and between boreholes. These cleaning ", procedures ensured that representative samples were obtained from each TSP. Nine TSPs were installed as part of this investigation (Figure 1) The TSPs were installed near the southern property line to further characterize shallow groundwater on the downgradient side of the landfill. TSP locations are summarized as follows: Temporary i a,INSampling On--or .

Due to the extensive amount of data collected during Golder's 1992 hydrogeologic and **�� geotechnical investigation, it was not necessary to collect soil samples. Accordingly, borehole logs were not prepared for the TSPs. I 2.2 Sample Point Installation Procedures The TSPs were installed by GEO in all boreholes drilled as part of this investigation. The GEO Expendable Aquifer Sampling Implant (EASI) was utilized for the TSPs. After the boreholes had been drilled to the desired depth, the EASI points were installed in completed boreholes. The end of the drill rod was fitted with an expendable tip and placed in the boreholes. One end of a 3/8-inch Teflonlan' tube was perforated with 1/16-inch holes over a 1-foot interval. The tube was then inserted into the drill rod and attached to the expendable tip. The drill rod was then removed from the borehole, exposing the perforated interval to the formation to allow groundwater to migrate into the tube. Ill The TSPs were completed by pouring 10-20 grit environmental grade silica sand into the borehole while agitating the 3/8-inch tube to prevent bridging. The sand was placed to a level approximately one foot below ground surface; granular bentonite was then placed from that point to ground surface and hydrated with deionized water. Final completion details differed between on-site and off-site TSPs. On-site TSPs were sealed with Parafilml°°'l; F. x Golder Associates 931061 I IN October 23, 1992 -4- 913-2403 I r completed with 1-inch diameter, 5-inch long PVC tubes; and, threaded caps were placed to INprotect the sampling point. Cement pads were constructed around the TSPs to prevent surface water infiltration. Locations were marked with survey stakes. Off-site TSPs were sealed with Parafilmom and attached to survey stakes.ll Figure 2 illustrates a typical "EASI" temporary sampling point. INAll TSP locations were surveyed by Stewart and Associates of Fort Collins, Colorado, on September 25, 1992. Ground surface and bottom of borehole elevations are provided in Table 2. ill ry 2.3 Sampling Procedures `■ EASI TSPs are designed to be sampled without development. Groundwater samples were collected from EASI TSPs upon completion; or, in the case of low-yielding points, when sufficient groundwater was present for sample collection. As discussed in Section 2.1, Drilling Operations, auger refusal was encountered at TSP-7 and TSP-8 prior to encountering PIthe water table; no samples were collected from these points. Groundwater samples were collected from the TSPs utilizing a peristaltic pump attached to N the 3/8-inch diameter tube, or alternatively, to a 3/16-inch diameter tube threaded down the larger tube. The alternative methodology was utilized when water levels were deeper than I 20 feet or the water contained a large percentage of silt. In those instances, the peristaltic lIll pump was not capable of creating sufficient vacuum to extract a sample. The 3-16-inch tube, unperforated, could be inserted into the larger tube directly to the water level, allowing the pump to extract a sample. PIGroundwater samples were collected in 20-milliliter (ml) volatile organic analysis (VOA) vials. The vials were immediately labelled and placed on ice in coolers for preservation. II Strict chain-of-custody procedures were followed, and the samples were delivered to Phoenix Analytical Laboratories (Phoenix) for chemical analysis. Copies of chain-of-custody forms -are included in the attachments. The samples were analyzed using EPA Method 8240 for llthe following parameters: I4 ► Vinyl Chloride; ► 1,1-Dichloroethene; ► 1,1-Dichloroethane; ► trans-1,2-Dichloroethene; ► cis-1,2-Dichloroethene; ill ► 1,2-Dichloroethane; ► 1,2-Dichloropropane; ll Golder Associates 9211)61 M October 23, 1992 -5- 913-2403 N ► Trichloroethene; and, ► Tetrachloroethane. The analytes include the six VOCs detected in the downgradient monitoring wells during the initial investigation, with the addition of vinyl chloride, a degradation product of the trichloroethene and tetrachioroethane series (see Table 1). It should be noted that trans-1,2- N Dichloroethene and cis-1,2-Dichloroethene results provided by Phoenix have been presented in Table 3 in a combined format as 1,2-Dichloroethene. This presentation format is consistent with the manner in which the initial investigative results were presented (see Golder, 1992). 3.0 RESULTS Results of chemical analysis of the groundwater samples are presented in Table 3. Copies of the Phoenix reports are included in the attachments. No target compounds were detected in the TSPs, with the exception of the confirmatory TSP-MW-5. Results indicate that VOC impacts to shallow groundwater on the south side of the landfill are limited to the immediate area of the landfill. A comparison of TSP-MW-5 results with GWMW-5 results is provided in Table 4. It should be noted that GWMW-5 results presented in Table 4 are from the sampling round conducted as a part of the initial hydrogeologic study. The comparison shows that the same compounds were detected in both sample points, although at slightly different concentrations. The slight differences in concentrations between the two sampling rounds could be the result of using different analytical laboratories. Additionally, the TSP drilling and sampling methodology may enhance volatilization of targeted compounds. The comparison indicates that the TSPs are a useful means of obtaining qualitative groundwater quality information for the site. ONCLUSIONS of the expanded hydrogeologic study, combined with results of the initial tippror: ation, suggest that the occurrence of VOCs in the shallow groundwater is isolated to ar areas. Elevated concentrations of VOCs were detected during the initial ation in the southeast and southwest corners of the landfill. VOCs were not detected center of the south side of the landfill VOCs were also not detected in off-site g points, with the exception of the GWMW-5 and TSP-MW-5 locations. The occurrences of VOCs may be the result of different types of waste disposed in these Golder Associates 93106a I October 23, 1992 -6- 913-2403 The 1992 initial hydrogeologic investigation concluded that the nearest permitted downgradient groundwater well is approximately 2,000 feet from the landfill. Detection of offsite VOC migration in the shallow groundwater was limited to very low 7 levels in TSP-MW-5 which was located approximately 23 feet south of the site boundary and immediately downgradient of GWMW-5. TSP-1, which was located about 200 feet further south, showed no VOC contamination. Accordingly, no water well users are being impacted by volatile organic compounds originating from the landfill. Any questions concerning the content of this report should be directed to the undersigned. Sincerely, GOLDER ASSOCIATES INC. s �r Christopher E. Rife NEngineer Technician Ward E.

Introduction: Waste Management Disposal Services of Cora lodo, AKA,' Waste services Corporation is the owner and opetator of the facility known as.the "Central Weld Sanitary Landfill" located between .Greeley and Milliken, Weld County, Colorado.` The Facility is operated .'under 'Certit'icate of Desi4ziation' No. '26 and Special Use Permit No. 11& criganaily issued; in 1971. It' is designed and operated to provide'!the- Central WBId Service Area with environmentally-sound, convenient and +cost-effective. disposal of non-hazardous solid wastes. 331061 Site History -- 1979 to Merger (1991 ) Role of Facility 1 . Site has served as the central component of the Weld County solid waste management system by meeting ongoing needs of more than 85 , 000 Weld County residents and most of our largest businesses . Feasibility Study conducted for Weld County in 1980 established service area concept for which site provides required capability for Central Service Area. (Please see Service Area Map) * This concept has been incorporated into the current Weld County Comprehensive Plan which projects a useful capacity for this facility of 20 to 60 years . Site Environmental Considerations 1 . Since 1979 , numerous environmental investigations of the site have been conducted and various environmental upgrades have been made toward assuring ongoing compliance and environmental protection. * A 1980 Geotechnical Investigation (Empire Labs . ) identified the need to install an underdrain beneath the western portion of the site to prevent impacts from artificial groundwater conditions caused by upgradient land uses . Study also established benefit of initiating the staged installation of a surface/groundwater diversion system to further protect site from unnatural groundwater conditions and surface water run-on caused by upgradient irrigation practices . A 1984 Hydrogeologic Assessment (Warzyn Engineering) affirmed benefit of continued staged installation of diversion system and established groundwater monitoring program. Groundwater monitoring program initiated to monitor upgradient and downgradient groundwater for base parameters under contract by Weld County Department of Health. 93106 Site Operational Considerations 1 . Effort made to operate facility in compliance with applicable regulations and compatible with surrounding agricultural land uses . * Record of compliance inspections conducted by Colorado and Weld County Departments of Health show consistent operational compliance history. • Endeavored to be good neighbor to surrounding neighbors . Future Regulatory and Industry Considerations 1 . A 1991 Subtitle D Preliminary Site Assessment found site could be made to comply with new EPA regulations . 2 . Internal assessment of ability of company ownership to meet increasing demands identified need for: * Greater environmental expertise * Financial strength * Longevity to shoulder perpetual responsibilities 3 . Concluded best alternative was merger with Waste Management due to assessment of their exceptional : • Commitment to serve county, customers and be a good neighbor * Competence to meet environmental , legal and operational requirements Capability to meet financial demands and long-term responsibilities Post-Merger Actions 1 . Waste Management has followed through by taking initiative and fully investing its expertise and financial resources in properly planning , investigating, upgrading and operating the facility. 931061 a l i r �- °. •/ If h [ Y.n. t nul yu r ��'' J Z£'" 1 d t g�4 1 ' ,,,, � ' _ .

Development of a hydrogeologic model Various investigations have been conducted at the site, including Warzyn, 1984; Industrial Compliance, 1991; Industrial Compliance, 1992; and, Golder, 1992. The Warzyn study included installation of five shallow groundwater monitoring wells(GWMW-1 through GWMW-5). Industrial Compliance's 1991 study included a conceptual design for the diversion ditch, as well as installation of seven trash piezpmeters and 10 piezometers (two of which remain active). The 1991 IC report included as-built drawings of the diversion ditch. Golder's 1992 investigation included installation of three additional shallow groundwater monitoring wells (GWMW-5N, GWMW-6, and GWMW-7), seven deep groundwater monitoring wells, 21 soil gas probes, seven geotechnical borings, and nine temporary groundwater sampling 1 931061 points. Golder's investigation also included sampling of each groundwater monitoring well, five surface water locations, and seven of the nine temporary sampling points (two were dry). The water quality results determined by Golder were subsequently confirmed by SEC Donohue. Based on the information collected during characterization activities, it has been determined that: • The landfill solid waste is not in contact with groundwater, with the exception of an isolated area near the northern boundary of the landfill (TP-1), where the groundwater table is maintained at an artificially high level by off-site irrigation activities; • Landfill gas concentrations are generally non-detectable, except near TP-1 where the concentrations are low. Landfill gas concentration distributions support the determination that solid waste is generally above the water table; • The diversion ditch and associated frenchdrain are functioning properly and as designed; • Shallow groundwater flow is generally from north to south towards the Big Thompson River, with slight southwest and southeast components of flow; • Deep groundwater flow is generally from northwest to southeast; 2 931.061 • The potential for communication between the shallow and deep groundwater system is low based on water quality comparisons and the presence of a dry zone between the two aquifers; • Limited volatile organic compound impacts have been observed in the shallow groundwater system on the downgradient side of the landfill; • No impacts on the deep aquifer have been detected; and, • The nearest permitted water well is approximately 2000 feet from the landfill, which is about 100 times farther than the extent of VOC impacts to shallow groundwater. 2. Definition of local/regional hydrogeologic setting The CWSL is located approximately 4000 feet north of the northern margin of the Denver Basin. The primary aquifer underlying the site is the Laramie-Fox Hills aquifer, although this area of the aquifer is outside of the Denver Basin. Even with the extensive drilling program conducted at the site, it is not possible to determine which of the two geologic formations (Laramie Formation or Fox-Hills Formation) underlies the site due to the geologic similarities of these two formations. However, final determination of the geologic unit is not necessary for the purposes of demonstrating compliance with environmental regulations or for 3 90 1.061. determining appropriate corrective actions. Three geologic units have been identified at the site: • The Surficial Unconsolidated Unit, • The Upper Weathered Bedrock; and, • The Lower Weathered Bedrock. The Surficial Unconsolidated Unit is a silty clay to clayey silt. The bedrock units range from sandstone to siltstone and claystone. It may be that the Upper Weathered Bedrock is the Laramie Formation, while the Lower Weathered Bedrock is the Fox-Hills Formation. Three saturated zones have been identified under the site. The first zone is perched, is present as a result of off-site irrigation activities, and is limited to the area near the northeast corner of the site. The second zone is approximately coincident with the top of the Upper Weathered Bedrock. The third zone occurs near the contact between the Upper and Lower Weathered Bedrock Units. Horizontal groundwater flow rate in the Upper Weathered Bedrock is approximately 95 feet per year (hydraulic conductivity of approximately 1 x 10' cm/sec, gradient of 0.03 ft/ft, and porosity of 0.3). Horizontal groundwater flow rate in the Lower 4 931061 Weathered Bedrock is about 2 feet per year (hydraulic conductivity of 2.5 x 105 cm/sec, gradient of 0.02 ft/ft, and porosity of 0.3). Downward vertical gradient generally exist between the two bedrock aquifers. However, the presence of the dry zone indicates that the potential for communication between the two aquifers is low. Assuming that they do communicate (a worst case scenario), data indicate that downward groundwater flow rate is approximately 0.05 feet per year (hydraulic conductivity of 2 x 10' cm/sec, gradient of 0.8 ft/ft, and porosity of 0.3). The very low potential downward flow rate indicates that groundwater will flow predominately horizontally. 3. Determination of Existing Environmental Conditions Through water quality sampling described in Item No. 1 above (which is much more complete than any sampling previously conducted and goes well beyond current regulations), it was determined that four volatile organic compounds (VOCs) were consistently present in the shallow groundwater on the downgradient side of the landfill, within the buffer zone. These are 1,1-dichloroethane; 1,2-dichloroethane; trichloroethene; and, tetrachloroethene. The maximum concentrations of 1,2- dichloroethane;trichloroethene;and tetrachloroethene slightly exceed State 5 93106t of Colorado and federal drinking water standards. VOCs were not detected in deep groundwater, indicating that the potential for communication between the two aquifers is low. No pesticides or herbicides were detected in any groundwater sample. This is important because the site was included on the CERCLIS due to alleged historic disposal of pesticide waste. Ammonia was detected in the deep aquifer, indicating that the deep aquifer is under natural reducing (anaerobic) conditions. The presence of nitrate in the upgradient shallow groundwater indicates that off-site irrigation is adversely impacting the quality of the shallow groundwater which migrates onto the landfill site. The cation/anion composition of the groundwater downgradient of the landfill was similar to the composition upgradient of the landfill, indicating that no significant change in water quality occurs as the water migrates beneath the landfill. Radionuclides and radioactivity appear to be natural and related to geologic materials occurring beneath and surrounding the site. 6 9:1.1)6' The only surface water sample which exhibited a detectable concentration of VOCs was the landfill underdrain outlet. The landfill underdrain outlet exhibited detectable concentrations of 1,1-dichloroethane and tetrachloroethane, each of which was present at or near the detection limit. Spomer Lake, which receives discharge from the underdrain, did not exhibit detectable concentrations of VOCs. No pesticides or herbicides were detected in any of the surface water samples. Nitrates were present in the surface water samples, again indicating that the surfaced water have been impacted by off-site irrigation activities. Major anion and cation concentrations were generally similar in all surface water samples, indicating that the surface water composition does not change appreciably as the surface water migrates around the site. Radionuclides and radioactivity were detected in the surface water samples as a result of the naturally occurring radioactivity in the geologic materials surrounding the site. Through a focused sampling of the creek water downstream of the landfill, it was determined that the milky-white color in the creek is probably being caused by natural conditions. 7 221.06' II. DEVELOPMENT, OPERATION AND CLOSURE PLANS CWSL is located 5 miles southwest of Greeley and 3 miles northeast of Milliken. The landfill boundary consists of 110 acres. The Design, Operations and Closure Plan along with the supporting Site Development Plan, describe the design, operation and closure methods to be used by CWSL. These methods meet all applicable government requirements, as well as, the draft version of Subtitle D regulations. The following is a list of site documents which cover design, technical evaluation and environmental programs. (Refer to poster board) 8 92 1.061. SITE DOCUMENTS 1.

"Interim Ground Water Measure Plan, Central Weld Sanitary Landfill", prepared by Golder Associates, Inc. dated March, 1993. A. DEVELOPMENT 1. Surface Water Management The landfill is located approximately 1/2 mile north of the Big Thompson floodplain. Surface drainage from the area is to the south toward the Big Thompson River. The surrounding area is primarily used for agriculture. Consequently, irrigation activities upgradient have required management of water levels within the landfill by the construction of a landfill underdrain, interceptor trench and the frenchdrain. The landfill underdrain and interceptor trench was constructed in late 1982 to 1983. The frenchdrain was constructed during 1991 and appears to be performing its function as geotechnical boring completed during the hydrogeologic investigation, and piezometer readings show that locations of the landfill downgradient hydraulically are dry. There appears to be a portion of the northwest corner of the landfill that information suggests that water levels have risen into an isolated pocket of the landfill. As part of an amended permit application submitted in March 1993, to 10 931.061. further enhance surface water management CWSL intends to do three things to lower water levels in this portion of the landfill. a. Construct a system of run-on, run-off perimeter ditches. The run- on ditch will intercept irrigation water and divert it along the north and toward an intermittent drainage on the eastern buffer property. Run-on in the northwest portion of the site will enter the site through an improved culvert system located along the northern property boundary. The water will then be conveyed to the west via a surface culvert to the upper most Spomer fake. This enclosed system will prevent any infiltration into the landfill in the northwest portion of the site. b. Extend the existing frenchdrain system in the northwest portion of the landfill. This drain will be installed approximately one foot below the base of refuse and below water elevations in TP-1. This system will collect subsurface irrigation water and convey the water to the west. c. An irrigation water control system which will collect subsurface irrigation water from upgradient sources and convey the water into the existing french drain. The combination of the extended 11 931,061. frenchdrain, surface water control diversions and the installation of the geonet are intended to lower water levels below the base of refuse in the northwest portion of the landfill. 2/3. Earth Work Requirements/Buffer Area Waste Service Corporation (WSC), has signed an agreement to purchase an additional 100 acres of land east, south and west of the existing site. This property will be used as a buffer. The landfill will not expand onto the buffer zone, rather, the buffer zone will be used for remedial measures and as a source of soils to be used in the operation and closure of CWSL. B. OPERATIONS The site is operated Monday through Saturday from 7:00 A.M. to 4:30 P.M. Appropriate signs are posted along the property boundary, entrance gate and on paved roads to allow for traffic control and safe disposal. Incoming waste loads are routinely inspected at the gate and again at the time of disposal. The facility has implemented a hazardous waste exclusion program and is further described in the Access Control Plan for Special Waste Identification. This program provides a plan to identify and screen both visually and through extensive analytical 12 9:1061. testing that no regulated radioactive waste, hazardous waste or PCB wastes are received at the site. CWSL does currently receive special wastes such as petroleum contaminated soils and medical wastes only after testing or other information indicates the material to be non-hazardous and non-infectious. Site operating procedures include actions to minimize nuisance conditions such as odor, dust, vector noise and litter control. 1. Fill Sequencing CWSL site development plans for the landfill calls for development of the landfill in six sequences. Generally the sequence begins in the north end of the existing fill and proceeds to the south. The fill sequence provides for a orderly approach to filling and approach to control surface water run-on/run-off. The development of the site also includes construction of a module comprising about 5 acres of the site which will include a liner and leachate collection system. C. ENVIRONMENTAL MONITORING 1. Ground Water Monitoring CWSL has implemented extensive environmental monitoring in anticipation of Subtitle D to include groundwater, landfill gas, and surface water monitoring. 13 9:i06 The groundwater monitoring program has been tripled from 5 wells to include an additional 10 shallow and deep wells, upgradient and downgradient of the site. The parameters have been expanded to meet the requirements under Subtitle D. Based upon the number and locations of the deep and shallow wells upgradient and downgradient, provides for a comprehensive monitoring network that closely monitors groundwater at the site. An additional three point of compliance wells are prepared to further enhance the monitoring program downgradient of the site. These wells are monitored on nine quality> bases for an extensive list of constituents, including metals, volatile organic compounds, radioactives and pesticides. 2. Landfill Gas Monitoring CWSL has also installed 20 gas probes around the perimeter of the site including the gate house and maintenance facility. Gas monitoring is currently conducted in a quarterly basis on all 20 gas probes. 3. Surface Water Monitoring Surface water monitoring is voluntarily done on a quarterly basis to characterize surface water entering and leaving the site. These surface water sampling points the north discharge point, the underdrain and 14 S21061, frenchdrain water. D. CLOSURE 1. Grading and Drainage The final elevation of the site is approximately 4870 which equates to approximately 40 feet higher than existing ground on the north area. The final contours of the site were designed to achieve proper drainage and blend in with the surrounding area to ease the concerns of height and view restrictions. The final cover side slope of 4.1 and minimum top slope of 5% were designed to provide consistent run-off while minimizing erosion and prevent ponding. The final cover on the landfill will consist of a total of 4.5 feet of soil. A six inch foundation layer, an 18 inch bather layer having a hydraulic conductivity of less than or equal to 1 x 10-6 cm/sec, a 24-inch thick protective layer and a 6 inch thick vegetative soil layer. 2. Revegetation All areas of fmal cover will consist of placing shallow rooted native grasses as recommended by the Soil Conservation Service. The buffer property consisting of approximately 100 acres will serve as soil for daily, intermediate, liner and 15 final cover. The approximate borrow volume within the secondary buffer area is 500,000. The final contouring of the excavated area will not exceed 25% slope, and will provide for positive drainage and improved agriculture production. E. POST-CLOSURE Upon the completion of site closure activities, post closure care will be conducted as required by State regulations. Post Closure will include: • Prevention or minimization of nuisance conditions • Site inspections of final cover and vegetative areas • Groundwater monitoring • Gas Monitoring • Security fence and enclosure inspections 16 924061. III. ENVIRONMENTAL COMMITMENTS A. Interim Groundwater Remedial Measure WSC acknowledges that shallow groundwater immediately downgradient of the landfill contains VOCs which are slightly above recognized standards and has committed to take actions to return these concentrations back to acceptable levels. Two primary mechanisms have been proposed to accomplish this goal: (1) re- designing the diversion trench and french drain and (2) evaluating the effectiveness of air sparging. Re-designing the diversion trench and french drain system is necessary to deal with the unnaturally high water table present upgradient of the land fill due to the off-site irrigation practices. It is anticipated that the re-design will effectively reduce the water table near TP-1 to below the base of solid waste and thereby remove the only verified source of impacts to shallow groundwater. In addition, in order to treat the existing conditions, a pilot-scale test of air sparging has been proposed. Air sparging is the process of injecting air into the groundwater to achieve remediation of the groundwater and saturated soils. Air injection wells are used to apply positive air pressure to the aquifer. Air bubbles contacting the dissolved/adsorbed compounds cause the compounds to volatilize. The air carrying the volatilized compounds is allowed to migrate to the ground surface 17 9:1.064 through natural mechanisms, or its migration is enhanced through use of vapor extraction wells. Naturally occurring biologic activity is also enhanced by air sparging. The pilot-scale test has been proposed to be conducted near GWMW-5, for the following reasons: • Monitoring well GWMW-5 generally exhibited the highest concentrations of VOCs in groundwater; • Monitoring well GWMW-5 is located in the general direction of shallow groundwater flow from the landfill; • Additional monitoring locations such as SG-9 and GWMW-5N are in close proximity to GWMW-5, which will provide supplemental data; and, • GWMW-5 is located on the buffer property, which provides sufficient room for proper installation and spacing of the air sparging well and observation points. Results of the pilot scale test will be used to determine the effectiveness of this remedial technique at the site and will be submitted to the CDH and WCDH for review. If the pilot scale test near GWMW-5 proves to be successful, additional air sparging wells will be installed at other locations near the site. If the air 18 97,1.064 sparging pilot scale test indicates that this remedial technique is not suitable for the CWSL, other remedial techniques will be evaluated. The CWSL, as currently sited meets the location restrictions under Subtitle D including: • Airports - not located within 10,000 feet of any airport • Floodplain- the landfill footprint is not located in a 100 year floodplain, according to the Federal Emergency Management Agency. • Seismic Zones - the CWSL is not located in an area of active faults. • Wetlands - the landfill footprint is not located in any wetlands. • Unstable Area - the landfill is not located in an unstable area. 19 91.06' Q y 2 N CC O I ;: U i Zcc cn Q �i i yyO� ��1 4. p m f 8 z g . a 52 ---..

THERE IS NO VIOLATION OF 30-20-103 FOR FAILURE TO SUBMIT AN ENGINEERING DESIGN AND OPERATIONS PLAN. A. 30-20-103 IS AN APPLICATION STATUTE - - IT PERTAINS TO THE MANNER IN WHICH ONE APPLIES FOR A CERTIFICATE OF DESIGNATION TO OPERATE A SOLID WASTE DISPOSAL SITE IT IS NOT AN OPERATION STATUTE. THE TEST IS WHAT WAS LAW AT THE TIME OF APPLICATION, NOT WHAT WHAT THE LAW IS NOW. IN ADDITION, 30-20-103 AND ITS PREDECESSORS HAVE NEVER REQUIRED, AN ENGINEERING DESIGN AND OPERATIONS PLAN -- THAT REQUIREMENT IS A CREATURE OF REGULATION -- SO WE MUST ALSO LOOK AT THE REGULATIONS OF THE STATE DEPARTMENT OF HEALTH IN EFFECT IN SEPTEMBER OF 1971. B. THE PREDECESSOR TO 30-20-103 WAS 36-23-3 WHICH WAS INITIALLY ADOPTED IN 1967 AND WHICH WAS AMENDED IN 1971 EFFECTIVE APRIL 24, 1971 THE 1971 AMENDMENT ADDED LANGUAGE TO 36-23-3 AS FOLLOWS: THE APPLICATION SHALL ALSO CONTAIN SUCH ENGINEERING, GEOLOGICAL, HYDROLOGICAL, AND OPERATIONAL DATA AS MAY BE REQUIRED BY THE DEPARTMENT BY REGULATION. TEE APPLICATION SHALL BE REFERRED TO THE DEPARTMENT FOR REVIEW AND FOR RECOMMENDATION AS TO APPROVAL OR DISAPPROVAL, WHICH SHALL BE BASED UPON CRITERIA ESTABLISHED BY THE STATE BOARD OF HEALTH, THE STATE WATER POLLUTION CONTROL COMMISSION, AND THE AIR POLLUTION CONTROL COMMISSION. ALSO AMENDED WAS 36-23-5 BY ADDING LANGUAGE: THE BOARD OF COUNTY COMMISSIONERS SHALL NOT ISSUE A CERTIFICATE OF DESIGNATION WHERE THE DEPARTMENT HAS RECOMMENDED DISAPPROVAL PURSUANT TO SECTION 36-23- 3. THE STATUTE PRIOR TO 1971 MANDATED THAT THE STATE DEPARTMENT OF HEALTH ENACT REGULATIONS GOVERNING THE OPERATION OF SOLID WASTE DISPOSAL SITES (DUMPS) AND REQUIRED NO INVOLVEMENT OF THE STATE DEPARTMENT OF HEALTH IN THE PERMITTING OF SOLID WASTE DISPOSAL SITES WHICH WAS THEN STRICTLY A COUNTY FUNCTION. INDEED THE SOLID WASTE DISPOSAL STATUTE WAS IN THE ARTICLE DEALING WITH COUNTY POWERS AND FUNCTIONS. 931064 THE 1967 REGULATIONS OF THE STATE DEPARTMENT OF HEALTH WERE BRIEF AND DEALT EXCLUSIVELY WITH OPERATIONAL MATTERS AND WE COMPLY. C. THE REGULATIONS ISSUED BY THE STATE DEPARTMENT OF HEALTH PURSUANT TO THE 1971 AMENDMENT WERE NOT ADOPTED UNTIL FEBRUARY 16, 1972, AND WERE NOT EFFECTIVE UNTIL APRIL 1, 1972. IN THEIR PRESENT FORM THEY CALL FOR AN "ENGINEERING DESIGN AND OPERATIONS REPORT". THIS FACILITY NOW COMPLIES WITH THESE REGULATIONS. IT IS NOT CLEAR FROM THE CURRENT REGULATIONS WHAT THE COLORADO DEPARTMENT OF HEALTH INTENDED WITH REGARD TO THE APPLICABILITY OF THE NEW REGULATIONS TO EXISTING FACILITIES INCLUDING THOSE PERMITTED AFTER THE EFFECTIVE DATE OF THE 1971 STATUTORY AMENDMENT AND BEFORE THE EFFECTIVE DATE OF THE REGULATIONS. AUSTIN N. BUCKINGHAM, GEOLOGISTS, HAZARDOUS MATERIALS AND WASTE MANAGEMENT DIVISION OF THE COLORADO DEPARTMENT OF HEALTH, IN A LETTER TO KENT E. HANSON DATED SEPTEMBER 18, 1992 STATED THAT THE 1972 REGULATION PROVIDED THAT ALL EXISTING FACILITIES WITH A CERTIFICATE OF DESIGNATION WERE "GRANDFATHERED". YOU NEED NOT RELY ON MR. BUCKINGHAM, HOWEVER, THE GENERAL ASSEMBLY IN THE 1991 AMENDMENT TO THE SOLID WASTE DISPOSAL ACT, WHICH IS NOW UNDER THE STATUTORY ARTICLE "HEALTH" PROVIDED: NO EXISTING SOLID WASTES DISPOSAL SITE AND FACILITY WHICH IS OPERATING PURSUANT TO A VALID CERTIFICATE OF DESIGNATION SHALL BE DEEMED TO BE IN VIOLATION OF ANY PROVISION OF THIS PART 1 BECAUSE OF ANY FAILURE TO COMPLY WITH APPLICATION PROCEDURES WHICH ARE ENACTED SUBSEQUENT TO THE ISSUANCE OF SUCH CERTIFICATE OF DESIGNATION. C.R.S. 30-20-103.5, SB 91-174, effective June 5, 1991. IF YOU ARE STILL NOT CONVINCED THAT THE REQUIREMENT OF A "ENGINEERING DESIGN AND OPERATIONS REPORT" OR "PLAN" DOES NOT APPLY TO CENTRAL WELD SANITARY LANDFILL, CONSIDER THE TESTIMONY OF ORVILLE STODDARD AT THE SEPTEMBER 22, 1971 HEARING BEFORE THE WELD COUNTY COMMISSIONERS. ACCORDING TO MR. STODDARD THE APPLICANT HAD ESSENTIALLY COMPLIED. HE STATED: THANE YOU. MY NAME IS ORVILLE STODDARD WITH THE ENGINEERING SECTION OF COLORADO DEPARTMENT OF HEALTH. THERE IS AN AMENDED ACT PERTAINING TO THE REGULATION OF LAND DISPOSAL SITES AND FACILITIES THAT EARL MOFFAT MENTIONED. THIS REQUIRES THE APPLICANT TO SUBMIT A REPORT OF ENGINEERING, GEOLOGICAL, HYROLOGICAL, AND OPERATIONAL DATA TO THE DEPARTMENT FOR REVIEW AND RECOMMENDED APPROVAL PRIOR TO THE ISSUANCE OF THE CERTIFICATE OF DESIGNATION BY THE COUNTY COMMISSIONERS. THE SITE WAS VISITED WITH MR. MOFFATT, GLEN PAUL OF THE WELD COUNTY HEALTH DEPARTMENT, AND AT THAT TIME THE GUILELINES FOR DEVELOPING THIS REPORT WERE REVIEWED WITH WITH MR. MOFFAT. HE DID SUBMIT A REPORT TO aT.31 • y THE DEPARTMENT, AUGUST 9, 1971, AND DID HAVE CONSIDERABLE INFORMATION OF THE TYPE WE WERE AFTER. THE INFORMATION SUBMITTED INDICATE(S) AFTER STUDYING THE SOIL REPORTS, THE TEST BORINGS, INFORMATION ON THE EXISTING WATER TABLE, SOIL CONDITIONS IN THE AREA, THAT THIS SITE CAN BE OPERATED IN ACCORDANCE WITH SANITARY LANDFILL REQUIRMENTS. ALSO, THE DEPARTMENT IS REQUIRED TO DEVELOPE AND PROMULGATE RULES AND REGULATIONS PERTAINING TO THE ENGINEERING DESIGN AND OPERATION. THESE ARE TO BE PRESENTED TO THE BOARD OF HEALTH AT THEIR REGULAR MEETING IN OCTOBER FOR ADOPTION. THIS IS A SUITABLE SITE AND CAN BE OPERATED AS A SANITARY LANDFILL. THE ONLY QUESTION WE HAVE AT THIS POINT IN TIME, AND MR. MOFFAT TOUCHED ON THAT, IS THAT THERE ARE SEVERAL ALTERNATIVES IN HOW THE OPERATION SHOULD PROCEED AND THIS IS JUST A MATTER OF DECIDING WHICH IS THE BEST WAY TO GO. Transcript of September 21, 1971 Hearing, Pages 4- 5. THEREFORE, IT IS RESPECTFULLY SUBMITTED, THAT THE REQUIREMENT OF 30-20-103 AND ITS ACCOMPANYING REGULATION THAT AN APPLICANT FILE AND ENGINEERING DESIGN AND OPERATION PLAN IS NOT APPLICABLE TO THIS SITE, AND EVEN IF BY SOME EXTENDED STRETCH OF THE IMAGINATION IT DOES APPLY, IT IS RESPECTFULLY SUBMIITED THAT IT WAS FOR ALL INTENTS AND PURPOSES COMPLIED WITH. II. ALLEGED VIOLATION 2. IT IS ALLEGED THAT CENTRAL WELD SANITARY LANDFILL DISCHAGES POLLUTANTS INTO THE SURFACE WATER WITHOUT THE REQUIRED DISCHARGE PERMITS. THE WATER QUALITY CONTROL COMMISSION IS THE AGENCY PRIMARILY CHARGED WITH ENFORCEMENT OF ITS RULES AND APPLICABLE STATUTES. THE ALLEGATION DEALS WITH THE LACK OF A DISCHARGE PERMIT FOR DISCHARGE FROM THE LOWER END OF THE UNDERDRAIN IN THE SOUTHWEST CORNER OF THE FACILITY. THE ALLEGATION DOES NOT DEAL WITH MILKY WATER OR ODORS FROM SPOMER LAKES OR THE STREAM WATER IN THE AREA. THE CONSENSUS OF OPINION OF THE CONSULTANTS OF WASTE SERVICES, INC. , AND THE COLORADO DEPARTMENT OF HEALTH IS THAT THESE DISTURBING PHENOMENA ARE THE RESULT OF CONTAMINANTS IN THE SURFACE WATER WITH COMPARABLE CONCENTRATIONS UP GRADIENT OF THE LANDFILL AND CANNOT, THEREFORE, BE ATTRIBUTED TO THE LANDFILL. WASTE SERVICES, INC. , WAS NOT AWARE THAT IT WAS DISCHARGING ANY POLLUTANTS INTO THE SURFACE WATERS SO AS TO REQUIRE A DISCHARGE PERMIT UNTIL THE MIDDLE OF 1992 AS A RESULT OF AN AGRESSIVE AND 931.061. EXPANDED TESTING REGIMEN THAT WAS INITIATED VOLUNTARILY BY WASTE SERVICES. THE ORIGINAL INTENT OF THE UNDERDRAIN WAS TO CONTROL GROUNDWATER LEVELS AND NOT TO DISCHARGE POLLUTANTS. THIS AGGRESSIVE TESTING INCLUDED THE INSTALLATION OF ADDITIONAL MONITORING WELLS FOR BOTH DEEP AND SHALLOW GROUND WATER, INSTALLATION OF TRASH PIEZOMETERS, AND INSTALLATION OF ADDITIONAL SOIL GAS PROBES. IN ADDITION, AND MOST DIRECTLY ON POINT, THE IT INCLUDED THE EXPANSION OF THE TESTING PROTOCOL TO INCLUDE A LARGE NUMBER OF ADDITIONAL CHEMICAL COMPOUNDS, INCLUDING VOLATILE ORGANIC COMPOUNDS AND METALS. VOC'S WERE DETECTED AT THE UNDERDRAIN DISCHARGE POINT WHICH DISCHARGES INTO, OR NEAR, SPOMER LAKE NUMBER 2. NO VOC'S HAVE BEEN DETECTED IN SPOMER LAKE NUMBER 2 OR AT ANY DOWNSTREAM LOCATION. VOC'S ARE VOLATILE AND ARE TREATED BY ULTRAVIOLET LIGHT. MANGANESE IS THE ONLY METAL DETECTABLE AT THE UNDERDRAIN IN CONCENTRATIONS DEMONSTRABLY IN EXCESS OF THE UPGRADIENT SURFACE WATER. APPLICATION FOR THE DISCHARGE PERMIT WAS MADE IN NOVEMBER OF 1992 AND IS PENDING AND THE ISSUANCE OF THE PERMIT IS EXPECTED IN THE NEAR FUTURE. BOTH THE COLORADO DEPARTMENT OF HEALTH AND THE WELD COUNTY PLANNING DEPARTMENT DO NOT SEEK ENFORCEMENT ON THE BASIS OF THIS TECHNICAL VIOLATION WHILE THE APPLICATION IS PENDING AND BEING PURSUED IN GOOD FAITH WITH DUE DILIGENCE. III ALLEGED VIOLATION 3 . THERE IS NO VIOLATION OF 2. 1.2 OR 2. 1.4 OF THE SOLID WASTE REGULATIONS WITH RESPECT TO THE OPERATION OF THE CENTRAL WELD SANITARY LANDFILL ALLEGED VIOLATION 3 DEALS WITH THE CONTAMINATION OF THE SHALLOW GROUND WATER WITH VOLATILE ORGANIC COMPOUNDS AND METALS (MANGANESE) . THIS CONTAMINATION IS MINOR AND WASTE SERVICES, INC. , WILL TAKE EVERY PRACTICABLE STEP TO REDUCE OR ELIMINATE IT. THE CONTAMINATION IS "MINOR" BECAUSE THE LEVELS DETECTED BARELY EXCEED THE GROUND WATER AND DRINKING WATER STANDARDS; THE MIGRATION OF THE CONTAMINATION IS VERY LIMITED; THE FUTURE MIGRATION OF THE CONTAMINATION, IF ANY, WILL BE EXTREMELY SLOW; AND THE REMEDIAL ACTION WHICH HAS BEEN SUGGESTED WITH KNOWN TECHNOLOGY CAN CORRECT IT. THIS CONTAMINATION WAS DISCOVERED BY WASTE SERVICES, INC. , AND REPORTED TO THE WELD COUNTY HEALTH DEPARTMENT AND THE COLORADO HEALTH DEPARTMENT IN MID 1992. 922.061 THE TESTING CONDUCTED BY WASTE SERVICES, THOUGH IT WILL BE UTLIMATELY REQUIRED BY REGULATION IN 1996 (SUBTITLE D) , WAS VOLUNTARY AND WAS CONDUCTED PURSUANT TO THE POLICY AND PRACTICES OF WASTE MANAGEMENT OF NORTH AMERICA, INC. THERE ARE REALLY TWO ISSUES WHICH ULTIMATELY HAVE TO BE DECIDED BY THE BOARD OP COUNTY COMMISSIONERS: 1. DOES THE PRESENCE OF VOLATILE ORGANIC CHEMICALS IN THE SHALLOW GROUNDWATER, WITHOUT MORE, CONSTITUTE A VIOLATION OF REGULATIONS OF THE COLORADO DEPARTMENT OF HEALTH, AS ALLEGED; AND, IF SO, 2. WHAT IS THE HEST COURSE OF ACTION, (1) THE PREMATURE CLOSING OF THE FACILITY FOLLOWING A SHOW CAUSE HEARING, OR (2) REMEDIATION AND CORRECTIVE ACTION WITH CLOSURE IN ACCORDANCE WITH APPROPRIATE DESIGN AND STANDARDS. THE SOLID WASTE DISPOSAL SITES AND FACILITIES REGULATIONS PROVIDE AS FOLLOWS: 2.1.2 SUCH SITES AND FACILITIES SHALL COMPLY WITH THE HEALTH LAWS, STANDARDS, RULES, AND REGULATIONS OF THE DEPARTMENT, THE WATER QUALITY CONTROL COMMISSION, THE AIR QUALITY CONTROL COMMISSION, AND ALL APPLICABLE ZONING LAWS AND ORDINANCES. 2.1.4 A SITE AND FACILITY OPERATED AS A SANITARY LANDFILL SHALL PROVIDE MEANS OF FINALLY DISPOSING OF SOLID WASTES ON LAND (1) IN A MANNER TO MINIMIZE NUISANCE CONDITIONS SUCH AS ODORS, WINDBLOWN DEBRIS, INSECTS, RODENTS, AND SMOKE; (2) SHALL PROVIDE COMPACTED FILL MATERIAL; (3) SHALL PROVIDE ADEQUATE COVER WITH SUITABLE MATERIAL AND SURFACE DRAINAGE DESIGNED TO PREVENT PONDING OF WATER AND WIND EROSION AND PREVENT WATER AND AIR POLLUTION; AND, (4) UPON BEING FILLED, SHALL BE LEFT IN A CONDITION OF ORDERLINESS AND GOOD AESTHETIC APPEARANCE AND CAPABLE OF BLENDING WITH THE SURROUNDING AREA. IN THE OPERATION OF THE SITE AND FACILITY, THE SOLID WASTES (1) SHALL BE DISTRIBUTED IN THE SMALLEST AREA CONSISTENT WITH HANDLING TRAFFIC TO BE UNLOADED; (2) SHALL BE PLACED IN THE MOST DENSE VOLUME PRACTICABLE USING MOISTURE AND COMPACTION OR OTHER METHOD APPROVED BY THE DEPARTMENT; (3) SHALL BE FIRE, INSECT, AND RODENT RESISTANT THROUGH THE APPLICATOON OF AN ADEQUATE LAYER OR (SIC) OF INERT MATERIAL AT REGULAR INTERVALS; AND S21O61. (4) SHALL HAVE A MINIMUM OF WINDBLOWN DEBRIS WHICH SHALL BE COLLECTED REGULARLY AND PLACED INTO THE FILL. 1.2 "NUISANCE CONDITIONS" ARE THOSE WHICH MAY RESULT FROM EXPLOSIVE GAS, BIRD HAZARDS, DISEASE VECTORS, ODORS, . . . WATER POLLUTION, AIR POLLUTION, NOISE POLLUTION, AND TRAFFIC CONGESTION. 3. 11.5 OF THE WATER QUALITY CONTROL COMMISSION REGULATIONS ESTABLISHES GROUND WATER QUALITY STANDARDS AND IS TOO EXTENDED FOR QUOTATION HERE. THE EXISTENCE OF CONTAMINANTS IS NOT A PER SE VIOLATION OF THE REGULATIONS. MORE MUST BE SHOWN TO SHOW A VIOLATION OF THE REGULATIONS OR PROBABLE CAUSE THAT A VIOLATION HAS OCCURRED. 2 . 1.4 OF THE SOLID WASTE REGULATIONS IS THE CENTRAL ISSUE. THE DISTINCTION BETWEEN; (1) MINIMIZE, AND, (2) PREVENT; IS IMPORTANT. MINIMIZE,, IS USED WITH RESPECT TO "NUISANCE CONDITIONS" WHICH INCLUDES, BY DEFINITION, WATER POLLUTION. PREVENT IS USED WITH RESPECT TO WATER POLLUTION AND PONDING RESULTING FROM [IN]ADEQUATE COVER WITH SUITABLE MATERIAL AND SURFACE DRAINAGE. THERE IS NO EVIDENCE THAT THE CONTAMINATION WHICH HAS OCCURRED IS THE RESULT OF INADEQUATE COVER, UNSUITABLE MATERIALS OR PONDING. THE EVIDENCE IS THAT: (1) THE COVER ON THE LANDFILL HAS BEEN REGULARLY INSPECTED DURING THE LIFE OF THE FACILITY AND HAS ALWAYS BEEN APPROVED; (2) THAT THE ONLY POND ON THE SITE IS NOT ON THE FACILITY AND DOES NOT CONTRIBUTE TO THE CONTAMINATION; (3) THE EVIDENCE IS THAT THE ONLY WATER IN THE LANDFILL IS THE RESULT OF RISING GROUND WATER TABLES NOT INADEQUATE COVER. (4) FLUCTUATIONS IN THE GROUND WATER LEVELS IS A FUNCTION OF OFF SITE IRRIGATION ACTIVITIES NOT ANY DEFICIENCY IN THE COVER. (5) FLUCTUATIONS IN THE GROUND WATER TABLE CAN BE ELIMINATED, OR SUBSTANTIALLY REDUCED, BY UPGRADIENT DIVERSION WHICH HAS BEEN UNDERTAKEN AND WHICH IS PLANNED. THEREFORE, THERE BEING NO DEFICIENCY IN THE COVER DESIGN OR MATERIALS, OR NO DEMONSTRABLE DEFECT IN THE DESIGN OR MATERIALS IN THE COVER, THERE IS NO VIOLATION OF 2.1.4 WITH REPECT TO "MINIMIZE" AND "NUISANCE CONDITIONS" INCLUDING WATER POLUTION, LET'S REVISIT THE LANGUAGE OF THE REGULATION WHICH STATES: 2. 1.4 A SITE AND FACILITY OPERATED AS A SANITARY LANDFILL SHALL PROVIDE MEANS OF FINALLY DISPOSING OF SOLID WASTES ON LAND (1) IN A MANNER TO MINIMIZE NUISANCE CONDITIONS SUCH AS ODORS, WINDBLOWN DEBRIS, INSECTS, RODENTS, AND SMOKE; 1. 2 "NUISANCE CONDITIONS" ARE THOSE WHICH MAY RESULT FROM EXPLOSIVE GAS, BIRD HAZARDS, DISEASE VECTORS, ODORS, . . . WATER POLLUTION, AIR POLLUTION, NOISE POLLUTION, AND TRAFFIC CONGESTION. THE TWO PIVOTAL TERMS ARE "MINIMIZE" AND "WHICH MAY RESULT FROM". THESE TERMS, OR PHRASES, PREVENT YOU FROM REACHING THE CONCLUSION THAT THE CONTAMINENTS IN THE SHALLOW GROUNDWATER, ALONE AND WITHOUT MORE, CONSTITUTE A VIOLATION OF 2.1.4. "MINIMIZE" CONNOTES A REALISTIC CONCLUSION THAT NO HUMAN ACTIVITY, INCLUDING THE OPERATION OF A SANITARY LANDFILL, IS WITHOUT ENVIORNMENTAL RISK OR ENVIORNMENTAL IMPACT. PERFECTION IS NOT EXPECTED BY THIS REGULATION. WHAT IS EXPECTED IS THAT THE OPERATOR WILL "MINIMIZE" THE CONTAMINATION. WASTE SERVICES, INC. , HAS FULFILLED ITS OBLIGATION BY: 1. AGGRESSIVELY TESTING, 2. PROMPTLY REPORTING, 3. PROPOSING AND TAKING REMEDIAL ACTION, 4. AND THE WILLINGNESS AND RESOURCES TO TAKE REMEDIAL ACTION WHEN APPROVED BY THE APPROPRIATE AGENCY OR AGENCIES. "WHICH MAY RESULT FROM . WATER POLLUTION" CONNOTES A REALISTIC REGULATORY CONCLUSION THAT CONTAMINATION IS NOT, IN AND OF ITSELF, A "NUISANCE CONDITION". A NUISANCE CONDITION "MAY RESULT FROM" CONTAMINATION OF THE GROUND WATER BUT NO SUCH RESULT HAS BEEN SHOWN TO EXIST NOR HAS IT BEEN DESCRIBED. THIS POSITION IS CONTRARY TO THAT APPARENTLY TAKEN BY THE WELD COUNTY HEALTH DEPARTENT AND THE COLORADO HEALTH DEPARTMENT WHO HAVE CONCLUDED THAT THE MERE EXISTANCE OF CONTAMINATION IS A "NUISANCE CONDITION. " IV. ALLEGED VIOLATION 4. VIOLATION 4 IS FOR ALL PRACTICAL PURPOSES THE SAME AS VIOLATION 3 IN TERMS OF THE INTERPRETATION OF THE REGULATION. IT ADDS THE ALLEGATION THAT THE OPERATOR HAS PERMITTED TRASH TO COME INTO CONTACT WITH GROUND WATER. TRASH IS IN CONTACT WITH GROUND WATER IN THE NORTH END OF THE FACILITY. THIS DOES NOT ARISE BECAUSE OF ANY COVER OR ON SITE DRAINAGE PROBLEM. THIS RESULTS FROM THE ENCROACHMENT OF GROUND INTO THE TRASH CAUSED BY UP GRADIENT SURFACE WATER USAGE. :106' REMEDIAL ACTION HAS BEEN PROPOSED AND IMPLEMENTATION OF SOME REMEDIAL ACTION HAS ALREADY OCCURRED. WASTE SERVICES, INC. , AND ITS CONSULTANTS ARE CONFIDENT THAT REMEDIAL ACTION WILL ELIMINATE THIS PROBLEM. THE VIOLATION NOTICE INDICATES THAT THIS CONDITION IS IN VIOLATION OF PROPOSED REGULATIONS. VIOLATION OF "PROPOSED REGULATIONS" IS NOT A VIOLATION. WHILE THE VIOLATION MAY HAVE BEEN IN VIOLATION OF REGULATIONS PROPOSED AT THE TIME OF THE NOTICE, IT IS NOT IN VIOLATION OF ANY EXISTING REGULATION OR ANY REGULATION CURRENTLY PROPOSED. THE SECOND QUESTION IS, IF YOU FIND THAT A VIOLATION EXISTS WHAT SHOULD BE DONE ABOUT IT. THE COURSE UPON WHICH YOU ARE NOW EMBARKED COULD LEAD TO A SHOW CAUSE HEARING WHICH COULD LEAD TO A TERMINATION OF THE USE BY SPECIAL REVIEW WHICH WOULD INEVITABLY LEAD TO A PREMATURE CLOSING OF THE FACILITY. THIS COURSE OF ACTION IS, AMONG OTHER THINGS, 1. CONTRARY TO THE RECOMMENDATIONS OF THE COLORADO DEPARTMENT OF HEALTH; 2. CONTRARY TO THE RECOMMENDATIONS OF THE WELD COUNTY DEPARTMENT OF HEALTH AND PLANNING; 3 . CONTRARY TO THE RECOMMENDATIONS OF ENGINEERING AND ENVIORNMENTAL SPECIALISTS RETAINED BY WASTE SERVICES, INC. ; 4. CONTRARY TO THE RECOMMENDATION OF WASTE SERVICES, INC. ; 5. CONTRARY TO A MORE COMPHREHENSIVE AND MODERN REGULATORY SCHEME ENVISIONED BY SUBTITLE D; and, 6. CONTRARY TO THE LONG TERM BEST INTERESTS OF THE ADJACENT PROPERTY OWNERS. WASTE SERVICES, INC., HAS BEFORE YOU A PROPOSALIFOR AMENDMENT OF SPECIAL USE PERMIT NO. 116 AND TO THE CERTIFICATE OF DESIGNATION WHICH, IF APPROVED, WOULD PROVIDE A COMPHREHENSIVE DESIGN AND OPERATIONS PLAN FOR THE FUTURE OPERATION OF THE FACILITY, MONITORING FOR ENVIORNMENTAL IMPACTS, PROVISION FOR CORRECTIVE ACTION IN THE EVENT OF ADVERSE ENVIORNMENTAL IMPACT, AND THE ORDERLY CLOSING OF THE FACILITY IN ACCORDANCE WITH CURRENT ENGINEERING AND ENVIORNMENTAL PRACTICES. THE PREMATURE CLOSURE OF THE FACILITY WITHOUT AN OPPORTUNITY TO DESIGN ADEQUATE ON SITE DRAINAGE AND WITHOUT ADEQUATE DRAINAGE CONTOURS WOULD BE A MISTAKE WITH LONG LASTING IMPACTS. Current Recommendations and Amendment Process 1. The present environmental concerns of the Facility have been fully addressed in the Amendment Application filed April 1, 1993 . 2 . The Facility should be allowed to continue to provide quality solid waste disposal service to our customers, the residents and commercial businesses of the Central Weld Service Area (see attached letters of recommendation) . 3 . The Amendment Application will be comprehensively reviewed by numerous governmental or quasi-governmental agencies through the normal referral process. Any additional comments which may be expressed about the Facility will be fully addressed in the amendment process. oy. 1 '93 15:44 4565 EDAP T . 303-352-2436 P. 2 CliIrlei*Iilat+IQI handy CREELEI(/WELD • March 31, 1993 Ms. Connie Harbert Chairperson Weld County Commissioners Centennial Building 915 10th Street Greeley,CO 80631 Dear Ms. Harbert, The availability of a regional state-of-the-art solid waste management facility is important to the retention and attraction of industry to Weld County. At a recent meeting of the Executive Committee of the Greeley/Weld Economic Development Action Partnership (EDAP), we reaffirmed the above statement and endorsed the process of re-permitting the Central Weld Sanitary Landfill. We encourage the Weld County Commissioners to favorably consider the re-permitting of the subject facility.

Box 758 Greeley, CO 80632 Dear Commissioners: It is my understanding that the Board will be discussing the Central Weld Sanitary Landfill on Monday, April 5, 1993. The continued availability of this conveniently located landfill for the disposal of solid waste generated within the City of Greeley is vital to our residents and businesses. I respectfully request you proceed with the process for considering an amended permit as quickly as possible. Concerns of area residents should be heard and considered, however sudden closure or prolonged delay in issuing an amended permit would be harmful to the economic future of Greeley. • If there is any assistance I can provide in this matter, please let me know.

GREELEY,COLORADO 60632 COLORADO March 25, 1993 The Honorable Natalie Meyer Secretary of State Department of State 1560 Broadway, Suite 200 Denver, CO 80202 Board of County Commissioners of Weld County 915 Tenth Street Greeley, CO 80631 Dear Secretary and Board: Pursuant to C.R.S. SS 24-18-109 ( 3) (b) and 24-18-110, this constitutes disclosure of an action which may have the appearance of impinging on my official duty and fiduciary trust. Currently pending before the Board of County Commissioners is the initial stage of a permit revocation process for a landfill operated by Waste Services Corporation, a subsidiary of Waste Management, Inc. This could be the first of a number of hearings which may result in the revocation or suspension of the permits to operate a landfill or which may in other ways affect the future course of operations of the landfill . I was elected to office in November of 1992 and took office on January 4, 1993. On November 8, 1992, following the election, I attended a Denver Broncos football game at the invitation of Brad Keirnes, the previous owner of Waste Services, Inc and watched the game from the Waste Management sky box. The value of the gift, which included tickets to the sporting event and food and soft drinks for myself and my wife, is not known, but I would estimate it to be less than $200 in value. I have reviewed the circumstances with Lee D. Morrison, Assistant Weld County Attorney, and he concurs with my view that this action does not breach any provisions of the Colorado Code of Ethics . Specifically, C.R.S . § 24-18-104 ( 1) and (3) address the issue of gifts and provide that a gift constitutes a breach of fiduciary duty and public trust only where it is of substantial value or economic benefit which tends to improperly influence a public /� �,4_P 930948 `62-CiIA3Ex ht- w \kii The Honorable Natalie Meyer Board of County Commissioners of Weld County Page 2 March 24, 1993 official or rewards the official for an official act. Specifically excluded from the definition of a gift of substantial value are items of perishable or non-permanent value including meals or tickets to sporting events. C.R.S. S 24-18-104(3) (f) . Furthermore, I was not a member of the Board of County Commissioners and could not have yet taken any official acts, and I do not believe that the invitation would improperly influence me to depart from a faithful and impartial discharge of my public duties. It is currently my intention not to recuse myself from any of the proceedings before the Board of County Commissioners involving Waste Services based upon this insubstantial gift. However, I would await receipt of any advisory opinion you are able to issue before making a final determination. Thank you for your attention to this matter.

Dear Mr. Baxter: C.R.S. 24-18-111 authorizes the Secretary of State to issue advisory opinions to persons subject to the provisions of C.R.S. 24-18-101, et seq. Please be advised that the opinion which is given is advisory only. Also be advised that the response made will be part of a public file, however your name and address will be deleted to protect your privacy. Your question is whether having attended a foothhl1 game before you were a Commissioner and sat in the box and participated in refreshments of a ccn any who will be appearing before the Cmmission is a violation of the Code of Ethics. First of all, the statute dries not address matters that happened prior to election. Therefore, at the time you attended the game you were not under the requirements of the Crrle of Ethics. Second, as you cited, C.R.S. 24-18- 104 (3) (f) specifically excludes tickets for 5pJrting events fran the category of gifts of substantial econanic value. Therefore, no conflict of interest occurred, no disclosure is required and recusing yourself fran the proceeding is not mandated. I trust the above answers your question.

In response to your first concern, the Central Weld Landfill was reviewed in accordance with statutes and regulations that were in place at that point in time. The use of a liner was not required. A landfill is usually allowed to take all wastes from a municipality except for statutorily designated hazardous wastes and radioactive wastes. Non-friable asbestos wastes, various household pesticides and similar materials can and do go into landfills. It was not until 1980 that some of the current restrictions on commercial wastes such as pesticides became law. Sludges may not be accepted unless they are dry and they do not contain hazardous levels of metals of the constituents. The discovery of low level volatile organic compounds in the groundwater at the southeast corner of the site has been fairly recent. The allegation of wastes placed into 5 to 25 feet of standing water is contrary to evidence presented to this department. Seven piezometers were installed in 1991 to measure the level of groundwater and three indicate that groundwater levels in the base of the landfill are as follows: Piezometer Jan. 1991 April 1992 Dec. 1992 TP-1 +1. 92 ft. +6. 34 ft. +3 . 03 ft. TP -6 +0.42 ft. -2 .75 ft. -2 . 67 ft. TP-7 dry dry +8 . 14 ft. These numbers indicate water levels into the base of the trash. The department has asked for the installation of three more piezometers in the affected area to better clarify this issue. 4 1, , A- Ri ty iyef m`dcd Pupa Sharon Davis March 31, 1993 Page 2 In reference to the special waste plan that has been given to the department, in June 1992 this document was hand delivered with a verbal request that it be kept confidential as proprietary business information. A letter was sent to Waste Management at the request of the Office of the Attorney General asking that the company affirm their claim to confidentiality per statute (see enclosed copy) . The department, by law, must honor the company's claim until such time a response is received. The fact sheet is public information and as such may be reproduced and distributed by anyone. It was drafted by the solid waste staff. Staff then asked the Water Quality Control Division, Weld County Health Department and Waste Management to review the draft. Comments that were received were considered when the final draft was prepared by staff. I hope that this response addresses your questions and concerns. Sincerely, ', ,,&.a MI NI? I Patricia A.
