BINH 1 r }}I'L.RS OF 4,(f<?C:v1.j Weld County Board of County Commissioners 1150 0 Street Greeley,., CO063 2 Dear Commissioners AGPROfessionais There have been discussions with regards to the road improvements for the Heartland Biogas, (HBCJJ facility located on Weld County Road 49 (CR49) directly north of Weld County Road 40 (CR4{]) , specifically the requirements to construct acceleration and deceleration lanes on CR49 at the existing access. There have also been discussions about installing the needed improvements to the intersection of CR 40 and abandoning the approved access on CR 49 and moving the i aci 1 ity access to CR 40 west of CR 49. HBG is agreeable to the concept of the relocation of the approved access and the required road improvements to CR 40 at an equitable exchange comparable to the construction costs of the turn lanes at CR 49. HBG requests forty lie (45) days to evaluate and review the construction requirements, easements and limitations of both CR 40 and the internal access road and all associated logistics and cost thereof. HBG will request additional bids for the construction of the original turn lanes to reflect current market conditions as well as costs for the internal road relocation and CR 40 improvements. In order to fully evaluate the engineering requirements of the intersection of CR 40 and the expansion of CR 40, HBG request the county's intersection and road design plans be provided to HB' ` s design engineer. HBG will not release the authorization to proceed with the above described review and evaluation until I-1BG is provided a response of basic agreement i th this by Weld Cproposal ounty.

INTRODUCTION Heartland Renewable Energy, LLC (Heartland) is proposing to design, permit, build and operate an anaerobic digester -based renewable energy plant for the primary purpose of producing pipeline grade natural gas from cattle manure and other organic waste streams. This traffic impact study updates the April 10, 2009 traffic impact study for this project. It reflects an access change, provides anticipated construction traffic, and addresses County comments of the earlier study. Heartland is located along the west side of Weld County Road 49 (CR 49) at Weld County Road 40 (CR 40). Access will be provided by a driveway to CR 49 north of CR 40. A vicinity map is presented in Figure 1. Key work tasks undertaken as part of this effort are described below. Obtain current traffic and roadway data in the immediate area of the site. Determine site generated traffic and distribute this traffic to the nearby street system. Estimate traffic for future roadway conditions. Evaluate traffic operations with the proposed facilities fully operational un- der future conditions. Identify areas of potential deficiencies. • Recommend measures to mitigate the impact of site generated traffic and other deficiencies as appropriate. r,L• R I14 r" 1511 County REAd 40 43 aUm CR-29 401 _ 38 O 4 SITE lila -.at 0 mi 2 3 copyright and IVJ 1989-2003 Munson curpere1cn anther its suppler* Pt rights reserved hilp llnw.v..mresosall com) tlrestsl tertian rnaKir4 Red 6:ection dale .' 2r>52, NAVTE O Ail rights reserved The Data for areas of Canada in;ludes tnfarrneton taken w th pennrssIcn tram Canadian aumoi fiat 'vj a tar rM'�d;es', top uteri c ix, Can+rda.

CURRLNT CONDITIONS A). Current Road Network CR 49 is a major north — south roadway extending from 1-76 to U.S. 34. It is a two lane roadway with a posted speed limit of 65 MPH. The site is located in the north- west corner of the CR 49 CR 40 (extended) intersection. CR 40 to the east of CR 49 is an unpaved two lane roadway which is under stop sign control at CR 49. Cur- rent roadway geometry is shown on Figure . Bb Current Traffic Conditions Traffic counts were undertaken in conjunction with this study. Traffic was counted at the CR 49 - CR 40 intersection between the hours of 7:00 AM and 9:00 AM and between the hours of 4:00 PM and 6:00 PM framing the typical highway morning and afternoon peakhours. The high continuous peak hour within the two hour count times represents the morning and afternoon peak hours. Traffic during these peak hours is shown on Figure 3 with count sheets provided in Appendix A. The County has indi- cated that the traffic counts seem low, but further discussion determined that they are within normal fluctuations. Capacity analyses were conducted at the CR 49 — CR 40 intersection using current traffic demands and the existing roadway geometry. Current operating levels of service are shown elow.

Capacity worksheets are provided in Appendix B. C). Surrounding Land Uses The site is currently vacant and is surrounded by rural and agricultural land uses. lll. SITE ASSUMPTIONS Heartland Renewable Energy, LLC is proposing to design, permit, build and operate an anaerobic digester -based renewable energy plant for the primary purpose of producing pipeline grade natural gas from cattle manure and other organic waste streams. This renewable energy gas production plant will use proprietary anaerobic digester technology that converts organic waste (cattle manure, food wastes, livestock processing. etc.) into a ►methane -rich gas which will be scrubbed of impurities and then injected into a natural gas pipeline. The plant will use technology in which an organic feed stock is placed in an air tight vessel where naturally occurring microbes digest the feedstock, and create methane and carbon dioxide which is captured and processed. In addition to generating a needed domestic energy source, the gas production plant will have other significant benefits including: 6 • Producing a high grade compost which can be used in agriculture, land recla- mation, landscaping, golf courses, gardening, greenhouses, erosion preven- tion and mitigation; • Capturing carbon dioxide which is a "greenhouse gas" for use in medical ap- plications, welding, refrigeration and other uses. • By using cattle manure, food wastes and other organic wastes as feed stocks, the digester facility will help preclude release of pollutants to the environment and, in particular, will preclude the emission of significant amounts of nitrous oxide A temporary batch plant will be located on -site during construction. Some 30 - 40 truckloads per day of aggregate, cement, etc. are expected, with 10 - 15 worker vehicles. Construction will be complete prior to the start of routine operations. Since construction traffic will be temporary and significantly less than normal operating traffic, i1is not considered critical. Routine site activity is expected to start in 2010 at about 50% and increase to full production about 6 months later. Given the short time between start up and full production, the site is assumed at full production at the onset of operations. Head- land will operate this facility 24 hours per day with three work shifts each having 5 — 8 employees. Shift times are expected to be from 7:00 AM — 3:00 PM, 3:00 PM 11:00 PM and from 11:00 PM - 7:00 AM. At full operation, the facility will generate some 70 — 90 trucks per day with relatively equal distribution over the 24 hour work- day" site visitors will be minimal with only 1 - 2 visitors per day. Peak site traffic will occur during shift changes. During these times 20 site trips are expected with a trip representing either an inbound or outbound traffic movement. Daily site traffic is expected to be 205 trips. The site will be served by a driveway along the west side of CR 49. It will be located about 900 feet north of CR 40 and will have with one lane in each direction. The 7 driveway will be paved as required by county standards. A field review of sight distance at the site driveway location was conducted. It was determined that with the driveway located on the roadway crest, about 900 feet north of CR 40, sufficient sight distance will be easily available. A concept plan for the Heartland site is provided on Figure 4. Site traffic is expected to arrive and depart the site equally to/from the north and south on CR 49. Anticipated site traffic shown on Figure 5. IV FUG URE CONDITIONS A). Background Traffic Background traffic was developed using straight-line growth based on County growth factors contained in the Upper Front Range Regional Transportation Plan. Background peak hour traffic is shown on Figures 6 and 7 for the short-term (2010) and long-term (2029) time frames, respectively. B). Total Traffic Total traffic (the combination of site traffic and background traffic) was developed for each future evaluation year. This information is shown on Figure 8 for the short-term and on Figure 9 for the long-term. 8 l'1 ill IA 1+- C- - • ri3e-s is a ) ;TV 4 V1(61(5 (b-scc (ut6) voted E) i11O1'99 sitniAg!Fi QflP ,16 t }:T',toil, i rJ 1,' 4 a nth `#_ 4 .

Vf.TRAFFIC IMPACTS En order to assess operating conditions with the Heartland facility fully operational. highway capacity analyses were conducted at the site access intersection. Short- and long-term conditions were evaluated, At the onset of these undertakings, peak hour traffic was reviewed at each intersec- tion to identify the need for new auxiliary lanes or an upgrade in traffic controls. Findings for each time frame are documented in the following sections, A). Short Term A review of peak traffic wasconducted to determine the need for auxiliary lanes at the CR 49 — site access intersection. C0OT's State Highway Access Code auxiliary lane criteria for R -B roadways and the existing 65 MPH speed limit were used in this assessment. It was determined that site traffic will not be high enough to warrant any auxiliary lanes at this intersection. Consequently, the short-term roadway geometry shown on Figure 10 is appropriate. This reflects existing conditions supplemented by the site driveway. Short-term operating conditions were evaluated at the driveway using highway capacity analysis procedures. Resultant 2010 levels of service with the Heartland facility fully operational are shown below. 15 41' 0 SITE Access 16 S r! sit s'ioP tryr CR40 Figure 10 SI I JRT-TCRM ROADWAY GEOMETRY SHORT-TERM OPERATIONS WITH HEARTLAND Intersection Control Movement/ Direction Level of Service AM PM CR 49 Access Stop NB LT A A.

Long Term A review of long-term peak hour traffic determined that no new turn lanes will be warranted at the CR 49 — site access intersection with Heartland fully functional, Consequently, the short-term roadway geometry was retained through the long-term. Long-term total peak hour traffic was loaded onto the short-term roadway geometry to reflect conditions in 2029. Resultant operating levels of service are shown below.

Capacity worksheets are available in Appendix D. 17 VII. CONCLUSIONS Based upon the above documented investigations and analyses, the following can be concluded. At full operation, the Heartland project will generate a minor amount of traf- fic with only 20 peak hour trips and 205 trips per day. These trips can be easily managed. • No improvements are needed to serve this development. • Site traffic can be accommodated by the existing roadway geometry at the CR 49 site access intersection. 9 11.1Vith this development level of service `Q' or better is expected for all peak hour traffic movements at the CR 49 — site access intersection through the long term . Accordingly, very acceptabie operations are expected for the fo- reseeable future. Long term conditions wilt, in fact, closely replicate current conditions. Sufficient intersection sight distance is expected at the planned site access location to CR 49. • The Heartland development is viable from a traffic engineering perspective. In summary, the existing roadway geometry supplemented by the site access to the west of CR 49 will facilitate acceptable operations for the foreseeable future. 18 APPENDIX A TABULAR SUMMARY 'NCR 49 VVCR 40 rite rsecti on Observer: Harry 'C O Weld Cctrniy.

Boring locations A . gcutcchnlica] site exploration was conducted by Soilogic in October 2014 tc7r the DPS site (See Appendix 3) . Two borings were advanced to a depth of30 (} feet beneath the proposed DPS Location_ Reportedly_ groundwater was not encountered in the F3-2 boring. Groundwater was encountered in the BB- I boring at a depth of approximately 29 feet below round surface e (bo,$). Twent y -tour hours following drilling., static water level in the B- I boring was measured at 27.5 feet hgs_ See Appendix * referenced above for maps of the boring locations and detailed findings_ ings_ This site is located in the Beebe Draw tributary of the South Platte Basin above the Laramie -Fox Hills Alluvial Aquifer. This confined aquifer occurs primarily in the lower sandstone units of the LaLonde Formation and the upper sandstone and s i Itstone units cinh e underlying yii1g Fox Hills likkirkr A ! II.

The eo]ogi ctil I orrisat scares of this aquifer are primarily composed of cretaceous and Tertiary said Lone.. conglomerate, and shale. The thickness of the aquifer ranges from zero at the boundary to between 200-300 feet in the central part of the basin. The Laramie Fox Hills Aquifer is underlain by nearly impermeable Pierre shale and on top consists of fine, to very fine. grained sandstone or si l tston e imbedded in the shale. Groundwater within the Laramie -Fox Hills Aquifer tends to contain small amounts of dissolved solids with concentration ranges from 200 to 2,000 rn i C l i grams per liter. Some gases, such as hydrogen sulfide and methane exist within the aquifer. The edges of the aquifer tend to have hard water, consisting of a sodium bicarbonate or sulfate. Depth to alluvial uroundwater within the aquifer generally ranges up to 250 feet. The preliminary geo to eh ii i ti a] report (Appendix L) did not i cli•eatc any groundwater within 25 feet of the existing grade surface. Subsequent drilling identified alluvial water at a depth of 42 feet in the center of the site, Several nearby wells indicate depth to groundwater ranges from 70- 2' 00 feet hgs. i1. Site Soils A Soils Report from the Natural Resources Conservation Service is provided to describe types of soils and engineering properties of the soils onthe site (See Appendix G). Approximately three to six inches of topsoil and vegetation were encountered at the surface during drilling. Beneath that was I i h t brown to brown silty sand and sandy lean clay. The three main strata were classified as a fine silty sand then sandstone to clayey sand in places, with a claystone layer existing between 25-50 feet The silty sand was generally medium dense to dense with occasional loose zones and showed low swell and low to moderate settlement potential with an increase in moisture content at current moisture and density conditions. Thesandy lean cal ay/cl ayey sand conglomerate was generally very stiff to hard in terms of consistency and/or medium dense to dense in terms of relative density and showed low swell potential and low to moderate consolidation potential at in -situ conditions. The silty sand and sandy lean clay/clayey sand conglomerate extended to the bottom ofborings B-3, B-4, B-5 and B -S at a depth of approximately 25 feet bgs. At boring locations B-1, B-2, B-6, B-7, 8-9, B-10, B-11, the silty sand and sandy lean cl ay:'claycy sand conglomerate extended to depths ranging from approximately 18 to 29 feet hgs and was underlain by brown/grey/rust claystone which varied to siltstuneisandstone in places. The claystone with siltstonc/sarrdstone was medium to very hard and slowed low to high swell potential at in -situ moisture and density conditions. Borings B-1, B-2. B-6, B-7, B-9, 13-10, B-11, were terminated at depths ranging from approximately 25 to 45 feet hgs in the claystone with siltstonc/sa.ndstonc bedrock. Natural Resource Conservation Service's (N RCS) soil report classified these soils as Valcnt sand and Vona loamy sand. Run -o H potential from this site is considered to he low because the soils are classified ied as well drained to excessively drained (See Appendix i) .

( o i to g ic) personnel have completed the geotechnical subsurface exploration you requested for the proposed Digester Processing System (DPS) facility to be constructed at the Heartland Renewable Energy site in Weld County, Colorado. The results of our subsurface exploration and pertinent geotechnical engineering recommendations are included with this report, We understand this project involves the construction of several above and below grade water tanks and associated pumping works and support improvements including a concrete pad and office structure at the Heartland Renewable Energy facility, located at 1 179 County Road 49 in LaSalle, Weld County, Colorado. The main storage tank (200,000 gallon) is expected to be approximately 36 feet in diameter and approximately 25 feet in height. We understand a ring -wall foundation is the preferred method for support of the 200,000 gallon tank. Several smaller and more lightly loaded rectangular storage tanks are anticipated including several buried 16 -foot cubical tanks and 32,000 gallon rectangular tanks with approximate plan dimensions of 12 feet by 40 feet and approximately 6 feet in height. Foundation loads for the 200,000 gallon tank are expected to be light to moderate with the tank bottom exerting approximately 2000 psfon the supporting soils. Foundation loads for the remaining area improvements are expected to be light with rectangular tanks exerting approximately 500 psf on the supporting soils and other structure loads estimated at continuous wall loads less than 3 kips per lineal foot and individual column loads less than 50 kips. Small grade changes are anticipated to devekp finish h site grades in the DPS area Soilogic, Inc. 3050 67a Avenue, Suite 200 • Greeley, CO 80634 • (970) 535-6144 P.O.

Weld c_:ourtty, Colorado Soilogic # 14-1208 2 The purpose of our exploration was to describe the subsurface conditions encountered in the completed site borings and develop the test data necessary to provide recommendations concerning design and construction of storage tank and associated supped equipment foundations and support of a concrete pad and exterior flatwork. The conclusions and recommendations outlined in this report are based on results of the completed field and laboratory testing and our experience with subsitrlit c conditions in this 'area. ITEaDESCI.IPTIO T The DPS area is situated on the south-central portion of the Heartland Renewable Energy site, located at 19179 County Road 49 in LaSalle, Weld County, Colorado. At the time of our site exploration. the proposed construction arc a had been stripped of topsoil and vegetation and was relatively flat, with the maximum difference in ground surface elevation across the proposed construction area estimated to be less than 2 feet. Evidence of prior building construction was not observed in the proposed construction area by Soilouic personnel at the time o I' our site exploration. EXPLORATION AND TESTING _PROCEDURES To de :c ]op su hsur I a c c in formation in the area of the proposed DPS improvements, two (2) soil borings were advanced to depths ranging from approximately 25 to 30 feat below present site grades within the proposed improvement area. The approximate locations of proposed site improvements were pre -marked in the Fuld by surveyors. The boring locations. were established in the field by Soilogic personnel based on the preniarked areas. A diagram indical ink, the approximate boring locations is included with this report. A graphic Log of each of the auger borings is also included. The test holes were advanced using 4 -inch diameter continuous flight auger powered by, a truck -mounted ('MN -55 drill rig. Samples of the subsurface materials were obtained al retn1]aC- intervals usiI`t;! Calilbmia barrel sampling, procedures in general accordance with AS Tt1 specification D-1586. :As part of the D-1586 sampling procedure, the standard Nan -wiling barrel is driven into the substrata using a 140 pound hammer Ii I l ing a distance C icotechriical Subsurface Exploration Report Tai �rtittir Proccssing System (DI'S) (a Heartland Rcncwahlc 1=,ncrQs f 19170 (-'ounty Road 49) LaSalle_ Weld County, Colorado Soilogic # 14-1208 3 o f 30 inches. The number of blows required to advance the samplers a distance of 12 inches is recorded and helpful in estimating the consistency. relative density or hardness o f the soils or bedrock encountered. In the California barrel t sampling procedure, lesser disturbed samples are obtained in removable brass liners. amp l es of the subsurface materials obtained in the field were sealed and returned to the laboratory for further e valuation_ c i i ss't [lea t ion and testing. The s'L1nzp lcs collected were tested in the laboratory to measure natural moisture content and visually c~ Ia ss it 1ed in accordance with the Li n i f ecl Soil Classification ion System (USCS). The USCS group symbols are indicated on the attached boring logs. An outline of the USCS classification system is included with this report. Classification of bedrock was completed through visual and tactual observation of disturbed samples. Other bedrock types could he revealed through petrographic analysis. As part of the completed laboratory testing. a calibrated hand penetrometer ('HP) was used to estimate the unconfined compressive strength of essentially cohesive specimens. The CHP P also provides a more reliable estimate of soil consistency than tactual observation alone. Dry density, -200 wash and swell/consolidation tests were completed on selected samples to help establish specific soil characteristics. The percent passing the #20(0 size sieve (-200 wash test) is used to determine the percentage of fine grained soils (clay and silt) in a sample. Swelliconsolidation tests are pct f o ivied to evaluate soil volume change potential with variation in moisture content. The he results of the completed laboratory tests are outlined on the attached boring logs and swell/consolidation summary sheets. SUBSURFACE CONDITIONS The subsurface materials encountered in the completed site borings can he summarized as LijJ t brown to brown silty sand was encountered at the surface at the boring locations_ The ~ silty sand was medium dense in terms of relative density, exhibited low swell potential at in -situ moisture and density conditions and extended to a depth of approximately 14 t Jet below ground surface at thelocation of boring B-1. At boring location. -2_ the silty sand extended to a depth of approximately 6 feet below ground surface and was underlain by brown to reddish brown/olive sandy lean clay.

The silty sand and sandy lean clay soils were underlain by grey/olive/brown s i It stone/sandstone bedrock with occasional claystone ysto ne interbeds . The s ilt stn ne'sand stone varied from hard to very hard in hardness, exhibited low swell pci i cn ial at in -situ moisture and d f as it y conditions and extended to the bottom of bot h borings at dept is ranging from approximately 25 to 30 feet below ground surface. The stnittgrap f ry indicated on the included boring logs represents the approximate location c r f changes in soil and bedrock types. Actual changes may be more gradual than those. Ind ieatetl Al the time of drilling, groundwater was encountered at boring location B-1 at a depth of approximately 29 feet below ground surface. Groundwater was not encountered at borinu location B-2 at that time. When checked approximately 4 days after, drilling. g 'oundwater was measured at a depth ofapproximately 271 feet below ground surface at boring location B-1. Boring B-2 had dry caved at a depth of approximately 21 feet below ground surface al that lime. Groundwater levels will vary seasonally and over time based 011 weather er conditions, site development, irrigation practices and other hydrologic conditions. Perched groundwater conditions may also he encountered at times throughout the year. Perched water is commonly encountered in soils overlying less permeable soil layers and/or bedrock. The location and amount of perched water can also vary over time. ANALYSIS AND RELCOMMENDATIONS Site Development Any existing topsoil and vegetation should be removed from ni all proposed fill and improvement areas. Alter stripping and completing all cuts and prior to placement orally till Or flat work improvements, we recommend the exposed subgrade soils be scarified to a depth 019 inches.. adjusted in moisture corateni and compacted to at least 95% of the materials standard Proctor maximum dry density. The moisture content of the scarified soils chnrr lEl hi: adjusted in be within ihe range or ±2% of standard Proctor optimum (kkotechnicai S ubmirlace Lxploration Report FDiE.csicr Processing System (PPS) 61, Heartland Renewable Energy L. J (19 l 79 County Road 49) LaSall+. Weld County, Colorado Soilogic # 14-1208 5 moisture content at the time of compaction. Fill soils required to develop the site should consist of approved, low volume change (INC) soils free from organic matter, debris and other objectionable materials. The site silty sand and sandy lean clay could be used as fill in this area. Suitable fill and backfill ll soils should he placed in loose lifts not to exceed 9 inches thick, ad.jusicti in moisture content and compacted as recommended for the scarified soils above. Care should be taken to avoid disturbing reconditioned subgrades and site fill soils prior to placement of foundation and flatwork con~rete. Soils which arc allowed to dry out or become wet arid softened or disturbed by the construction activities should be removed and replaced or reworked in place prior to concrete placement. Foundations Based on the materials encountered in the completed site borings and results of laboratory testing, it is our opinion the proposed 200.000 gallon storage tank could be supproiled 011 a ring.rwall foundation and other more lightly loaded tanks and support structures could be supported by continuous spread fboting and isolated pad ibundaiions bearing on natural, undisturbed silty sand, sandy lean clay or si lt.stone/sandstone bedrock with low volume change potential. Each site structure should be supported an like materials in order to reduce the potential for excessive differential movement. If differential inunda1 ion bearing conditions are observed at the time of construction, extending footing foundations to bear on similar soils bedrock at greater depth or development of a uniform thickness of overexcavation/hack fill beneath spread footing foundations would be required. We recommend staged loading of the 200,000 gallon tank be completed upon initial filling tc allow ltor1 monitoring of total and differential 1 ou ndat ion sett [einemmt . For desitzu of the 200,000 gallon storage tank ring -wall spread {timing lbundation and other more Iight1 -] Jaded tank and structure foundations bearing on natural. undisturbed, medium dense silty sand and/or very still sandy lean clay with low volume chtr rt e potential, we recommend using a maximum net allowable soil bearing pressure of 2.000 .L psi 6, c:OA:clinical Subsurface Exploration Report Digester Processing System (1)1'S) ( i Heartland Renewable 1';nerg , L• 19179 county Road 49) LaSalle., Weld County. Colorado Sollogic # 14-1?08 6 Exterior footings should bear a minimum of 30 inchesbelow finished adjacent exterior grade to provide frost protection. We recommend formed strip footings have a minimum wid th of 12 inches and isolated pad foundations have a minimum width of 24 inches in order to facilitate construction and reduce the potential for development of eccentrically loaded ibu'imgs. Actual looting widths should be designed by a structural engineer, For design or l oting l aundations and foundation walls to resist lateral movement, a passive equivalent llr.rid pressure value of 250 Pct~ could be used. The top 30 inches of subgracic could. be considered a surcharge load but should not be used in the passive resistance calculations, A coefficient of friction of 0,45 could be used between foundation and tl o or slab concrete and the bearing soils to resist sliding. The recommended passive equivalent fluid pressure value and coefficient of friction do not include a factor of safety. We estimate settlement of the 200,000 gallon storage tank designed and constructed as outlined above and resulting from the assumed structural loads would be 2'/2 inches or less. if this amount of settlement must he reduced, ovcrexcavation/hack i j 1 l procedures or other alternative deep foundation systems could be employed. Removal of the upper 5 feet of silty sand and replacement with select granular fill compacted to at least I00% of the material's standard Proctor maximum dry density and within +2% o f` standard Proctor ittionurn moisture content would be expected to reduce the anticipated settlement of the 7)00,000 gal Ion storage tank to I -A inch or less. We estimate settlement of the 32,000 gallon above -ground storage tanks and other lightly -loaded spread looting foundations deskned and constructed as outlined above and resulting from the assumed structural loads would he less than I inch. We estimate settlement of the buried storage tanks result iffy from the assumed structural loads would be % inch or less. Differential settlement would he expected to be more limited, approaching 75% of the total settlement estimated above. If water from any source is allowed to infiltrate the foundation bearing soils, add it iona l movement of i o u nd at ions could occur-. Seismicity Based on our review of the International Building 'ode (2003)., a soil profile type C could be used for the site strata.

Concrete Pad and Exterior Flatwork The conercte pad mid exterior flatwork could be supported directly on the reconditioned natural site. suds andicir properly placed and compacted fill soils developed as outlined lined in the "Site Development" portion of this report, A modulus o l' subgrade reaction 00 value of 150 pci could be used for design of slabs supported on the native silty sand and sandy than clay soils_ Disturbed subgrades or subgrace materials that have been allowed to dry out or become wet and softened should be removed and replaced or reconditioned in place prior to pad and exterior flatwork construction. I rains ;e Positive drainage is imperative for satisfactory long-term performance of the proposed site improvements. We recommend positive drainage be developed away from the structures during construction and maintained throughout the life of the site improvements. with twelve (1 2) inches of fell in the first 10 feet away from the tanks and as ..ie iatecf site improvements. Shallower slopes could he considered in hard scape areas. Tai the event that some settlement of the hackfi ll soils occurs adjacent to the tanks, the original grade and associated positive drainage outlined above should be immediately restored. We recommend irri ,atron systems (if any) be placed a minimum of 5 feet away from the perinicu er of the site structures and he designed to discharge away from all site improvements_ 'atcr which is allowed to pond adjacent to site improvements can result in unsatisfactory performance of those improvements over time. t.i : xteelraiiccal Subsurface Exploration Report L)i c t'r Processing System (DPS.)

In low permeability soils. the accurate determination of groundwater levels may not be possible with only short-terrtn observations, DESCRIPTIVE SOIL CLASSIFICATION: Soil classification is based on the Unified Classification System. Coarse Grained Soils have more than 50% of fir dry weight retained on a #200 sieve; their principal descriptors are: boulders, cobbles, gravel or sand, Fine Grained Soils have less than 50% of their dry weight retained on a #200 sieve; they are principally described as clays if they are plastic, and silts if they are slightly plastic or non -plastic. Major constituents may be added as modifiers and minor constituents may be added according to the relative proportions based on grain size. In addition to gradation, coarse -grained soils are defined on the basis of their in -place relative density and fine-grained soils on the basis of their consistency.

The Colorado Department of Public Health and Environment, Hazardous Materials and Waste Management Division (the "Division") views the addition of the DPS is an operational issue, and not a substantial change to the provisions of the Certificate of Designation (CD). Therefore, the Division does not consider changes to the Heartland CD as being necessary.
