Avenue Address: 3696 1st Avenue, Greeley, CO 80634 (south of 37th Street) Dear Mr. John Pipe and Ms. Angela Kelley: This is a notification about a historic landfill on parcels 096128000001 and 096128000002. The County records indicate that one of these parcels is under the ownership of your business. These two parcels are part of an historic landfill that was created in 1970. A Certificate of Designation (CD) #23 and SUP -46 (USR-46) was approved by the Weld County Board of County Commissioners for a landfill on April 22, 1970 (document # 700278). The applicant for this CD/USR was Mr. Earl Moffat. On February 1, 2023 Weld County Department of Planning Services met with Colorado Department of Public Health and Environment (CDHPE) representation Mr. Jerry Henderson to discuss this site. Mr. Henderson expressed concerns with any type of development on the identified landfill location and submitted a letter outlining the concerns dated February 24, 2023. Background about an unknown landfill just west of the site: Between September 11 — September 13 of 2013 there was an unprecedented flood event along the front range. The flood breached berms and uncovered an unknown landfill located in the City of Evans just west of the subject property. The area of the 'unknown' landfill extended about 1.5 miles along a northeast/southwest route on the north bank of the South Platte River between U.S. Highway 85 and 37th Street (CR 54). See Exhibit B. Per a report provided by the City of Evans there was trash and debris GotAMun;cO..+;onS O3/22./23 2023-0802 'PLo/3o scattered throughout the area. The debris included items typical of a municipal solid waste landfill, like construction and demolition debris and items typical of an unregulated landfill like tires, deteriorated 55 - gallon drums, and engine oil filters. Medical waste (syringes, IV drip bottles) were also found on the site and as debris in the landfill material. The extent and depth of the landfill is not known. The report indicates that no city, state, and county records could be located concerning the `unknown' landfill. Five years later, a 2018 article from the Greeley Tribune by Sara Knuth, stated that. "...decades before the 2013 flood, Riverside Park [in the City of Evans] was a makeshift landfill, It was never an official dumping ground, so officials can't know for sure when people started throwing trash there. But they figured it started sometime in the 1960s and they knew there was enough trash to create even more problems as the city started cleaning up after the flood. When the berm broke and sent water gushing into the park, ... it wasn't just water that came tearing through — it was also trash. There was trash everywhere. Officials had to haul away 75,000 tons of trash; the trash filled up 5.3 million 30 -pound trash bags." Based on the City of Evans' history in this area concerning the unknown, now known, landfill and the comments from the CDPHE Weld County will not issue permits for development on these sites including Site Plan Review permits, Use by Special Review permits, grading permits, etc. As long as this site is part of unincorporated Weld County no development shall be allowed on these two parcels especially mining or digging.

During the meeting, Weld County requested that the Hazardous Materials and Waste Management Division of the Colorado Department of Public Health and Environment (division) provide comment on the regulatory status of Parcel # 096128000001 with the property address of 3696 1" Avenue (528, T5, R65). The reason for the request is that this parcel was used as a landfill in the early 1970s and is now subject to a potential property transfer. Specifically, the County requested that the division provide a memo outlining its position on this type of site, generally, and specifically any concerns regarding this site, including what is necessary for the site going forward. Background: The Weld County Commissioners issued a certificate of designation (CD) to an individual named Earl Moffat for a sanitary landfill on the subject property in April 1970 (CD No. 23). Subsequent records in division files directly or implicitly related to this property indicate landfilting did occur on the property. The division has no information on the extent of landfill operations. However, an aerial photograph series provided as part of a Phase I investigation suggests the landfill operations may have ceased by 1975 and the property may have been converted to a surface material storage yard by 1984. The division has no documentation on the exact timing or the manner of landfill closure. Generally speaking, a property designated historically as a solid waste landfill warrants that certain precautions be taken regarding future land use changes and decisions, and that additional requirements and regulatory approvals be satisfied prior to future development. Following are key things to be aware of. 1. Materials Management Plan: In the event regrading is planned, or utility line work or any waste or landfill cover disturbance is to be performed, the property owner must develop a materials management plan to safely manage excavated waste. This plan should be submitted for regulatory review and approval prior to conducting the disturbance. If the planned disturbance entails disturbing landfill cover, the site should have a plan for restoring the cover to its previous condition. 2. Explosive Gas Concerns: If any structures are being considered for the property, the property owner should either: 1) conduct a flammable gas survey to rule out the likelihood of explosive gas collecting in a future building, or 2) design the building with a subsurface gas control system. Explosive gas monitoring in any existing structures is also recommended; however, the division understands there are no existing structures on the property. 3. Nuisance conditions: Any active or affirmative requirements and obligations pertaining to the CD have effectively expired with the passage of time and subsequent changes in ownership (i.e. the person to whom the CD was issued is no longer involved in the site). While the current property owner may not have active landfill 4300 Cherry Creek Drive S., Denver, CO 80246-1530 P 303-692-2000 www.colorado.gov/cdphe Jared Polls, Governor Jill Hunsaker Ryan, MPH, Executive Director Diana Aungst, Weld County Planning February 24, 2023 Page 2 maintenance responsibilities absent changes in land use or the type of intrusive disturbance outlined above, there does remain a fundamental obligation to address nuisance conditions that may arise due to the closed landfill. Examples of the types of nuisance conditions that can arise are (not meant as an exhaustive list): subsidence causing water ending on the site, expression of leachate at the surface, daylighting of waste at the surface, or groundwater pollution originating from the waste that is migrating outside property boundaries. During the discussion, Weld County asked about the process for vacating a certificate of designation (CD). There can be value in the local governing body vacating or revoking a CD for reasons of noncompliance, forcing a non- compliant facility to cease operations. In the present case, CD No. 23 appears to be an historical document whose primary value lies in informing current and future users of the property as to the existence of a landfill on the property. For this reason, the division views vacating the CD to be unnecessary and potentially misleading, especially if vacating the CD were misconstrued as an indication that the site no longer poses any risk. According to state solid waste law, CDs are issued to a specific owner or operator of a solid waste facility and cannot be administratively transferred to another entity. Thus, the permission to dispose of solid waste that the CD granted to a particular individual in 1970 does not transfer to current or future property owners. A final question from the meeting warrants a response. The question, as the division understands it, relates to whether the current or future owners of the property should be required to provide proof of landfill closure as part of vacating the CD. While closure certification is a requirement for sites that close today, the division is not aware that solid waste landfills closing in the 1970s followed a standard process. It is the division's experience that closure documentation during this time frame varied considerably from site to site. In general terms, regarding closure of landfills from the 1970s, unless there was evidence of a subsequent disturbance to the closed landfill, or the observation of some nuisance conditions needing to be addressed (e.g. exposed waste), the division would not require current owners to re -close or re -perform closure activities and have a P.E. certify them. However, as alluded to above, if current or future owners disturb final cover for any reason, they may be required to have a P.E. certify cover repairs.

Cite of Evans, Colorado To: Charles Johnson, Manager Solid Waste and Materials Management Program Hazardous Materials and Waste Management Division Colorado Department of Public Health and Environment From: Warren Jones, Flood Recovery Manager City of Evans Re: Evans Riverside Park Redevelopment and Landfill Project Date: January 23, 2015 The purpose of this memo is two -fold. First, to bring you up to date on the Evans Riverside Park Redevelopment Project which includes the full or partial removal and treatment of an exposed landfill and second, to request documentation from CDPHE on your expectations of the landfill treatment. Evans Riverside Park Redevelopment Project In 2014, the City of Evans commissioned a parks master plan with a major objective of determining the future of Riverside Park which was completely destroyed by the 2013 flood. This park is fully contained within the 100 year flood plain. This plan is complete and in November of 2014, the Evans City Council approved a conceptual design for the redevelopment of Riverside Park. A major part of this design will raise portions of the park above the 100 year flood level and lower a non -certified berm separating the park from the South Platte River. As you know, this berm failed and was overtopped in several locations completely destroying the park and two mobile home parks, seriously damaging many single family homes and the Evans Waste Water Treatment Plant, and exposing a landfill that had been abandoned to the best of our knowledge in the early 1970's. This new design will create a resilient and sustainable park by restoring the historic flood plain and river eco-system between the South Platte River and eastern portions of Evans. As you know our entire recovery, and the park project in particular has been greatly complicated by the exposure of the old landfill. To complicate this further the berm is made up largely of landfill materials. After much work on various aspects of our flood recovery we're de-emphasizing reference to the landfill as a separate and distinct issue and are now referring to it as unstable and unsuitable soils that cannot be reused in the park project. Attached is an RFP for the first phase of engineering and design services 1 for Riverside Park. On page 5 is the specific requirement regarding the landfill. We expect that the consultant selected to do this work will be contacting you and your staff. Unsuitable Soils removal The Consultant will create a design and estimate costs for the removal of soils that cannot be reused on -site. Included must be a design for the partial or full removal of landfill materials and treatment (or capping) of remaining landfill materials if the entire landfill is not removed. CDPHE Expectation on Landfill Treatment We've met with you and other representatives of CDPHE on several occasions and while we have discussed CDPHE's expectations and requirements for the landfill, we do not have any written documentation. The notes I have from our meeting on October 22, 2014 are that CDPHE would not require the removal of the landfill, but will require that the exposed areas be restored to their condition prior to the flood. Additionally, if the entire landfill is not removed what is left must be properly stabilized and capped. Are these correct? Also, what CDPHE standards will be used and what permits will be required by CDPHE for the landfill treatment and/or removal? Thank you for your help so for in our recovery and we looking for forward to working with you and your staff as our park redevelopment progresses. 2 Here are my observations from our meeting at the State yesterday. I didn't take notes so please send me corrections or additions if you did take notes. I didn't get a good list of everyone who was there, especially the FEMA and CDPHE guys across the table from me. Here are some of the main players; Roger Jones, lain Hyde, Kevin Kline, Dan Alexander, Steve Boand, Charles Johnson, Ron Pevan. From us Aden, Scott, Brian and me. • Everyone seemed to understand the history of the berm and landfill and no one seemed to want to contest who did what to who and when. • Lots of discussion on the current PWs and how they can be manipulated to accomplish multiple objectives. Between the berm repair, park repair and/or alternate project and trails repair there is several million dollars. • However, no PA money can be used for landfill removal. It seemed to be a strong consensus that landfill removal would have to be a CDBG-DR infrastructure project. No one offered any other suggestions for funding this. • Brief discussion on our current CDBG NOls for the berm repair, landfill removal and park. Folks seemed to be impressed that we had the forethought to do this. Thank you Sheryl....... • There seemed to be support for the park proposal and recognition that the landfill would have to be removed to make it happen. • There was strong direction that the City (City Council) has to adopt a park proposal to move forward with a CDGB application and the next level of review by the State and FEMA and the n ext round of feasibility study to link the proposal with the actual implementation. Related to this any proposal that changes the current flow and functioning of the river needs a special review (not sure of the name of this). This will be a big deal and be part of the feasibility study. • Some discussion on the feasibility study and what needs to be included in this. Still a lot of work n eeds to be done defining a scope of work. Some discussion on how much of this can be done u nder our current GOCO grant. If we need to do a separate study it could be funded by a CDBG- DR planning grant in the next round later this year. We were reminded by our friends at DHSEM that procurement requirements would apply. (Later discussion on the way back was that we have to know what this feasibility study will contain to determine if we can extend our current THK contract. This could save time and eliminate the need for a separate study. We are working on a meeting the week of Oct. 20 with the state to do this.) • Significant discussion on berm repair PW. This could be an extension of the current PW or a CDBG project. Talked some about the dilemma of design standards and how they would affect funding. FEMA was very non -committal on this and we still can't get a straight answer on if they will pay for repairs that don't meet USACE standards. Like the park they want us to submit a proposal on what we want to do. Overall I didn't learn anything new from this meeting. We mostly covered already known information. Everyone pretty much restated their previous positions. The one thing I did pick up was the need to get our proposals on the table so that the others involved can evaluate them. I think we're only a few weeks away from this for the berm repair and park. TASKS THK Associates Atkins TOTALS Program Asst.

New channels were cut through the cap and into the landfill debris, spreading debris across the Site. Material identified included that typical of a municipal solid waste landfill, including construction and demolition debris. Items typical of an unregulated landfill were also identified, including tires, deteriorated empty 55 -gallon drums and engine oil filters. Pre -1970s tires and the lack of plastic bottles suggested that the landfill was pre -1980. Medical waste (syringes, IV drip bottles) were also found on the Site and as debris in the landfill. The extent and depth of the landfill were evaluated by FEMA and no hazardous material were found, however the trash remains as a flooding and debris hazard on site.

It states the background, the problems and future actions. The City is requesting technical and financial assistance to determine a course of action that meets the recovery needs of the City, the sustainable and resilient redevelopment of Riverside Park and stewardship of the South Platte River. Overview of Evans, The Queen City of the South Platte • Approximately 20,000 residents located on the northeastern plains of Colorado • 300 acres of parks and open space • Elevation 4650 • 10.5 square miles • 4 elementary schools • Middle school opening Fall 2015 • 165 storefront businesses Flood Event September 13, 2013: Up to 15" of rain fell on the Front Range between Wednesday, Sept 11 and Friday, Sept 13, resulting in the South Platte River peaking in the earning morning hours of Saturday, September 14 at 18.79 feet, well exceeding the previous record of 11.7 feet in 1973. The flooding lasted longer than expected and the river stayed above 12 feet (major flood stage) until Thursday, September 19 and the South Platte grew to almost 1 mile wide at its peak. Significant breaches along the banks of the river occurred in the morning Friday, September 13, increasing the depth and intensity of the flood in an extremely short period of time. A heretofore unknown to current City staff landfill immediately adjacent to Riverside Park was uncovered by the flood waters and the contents of the landfill were exposed and carried downriver, with debris ending up in residential neighborhoods as well as on public park lands. When this landfill was discontinued in the early 1970s it was incorporated into a locally constructed berm that now comprises the north bank of the South Platte River for a distance of in the City of Evans. (Please see the attached map) Problem Statement The flood event uncovered the landfill and at the time little was known about what area it covered, what it contained, when it was opened or closed, or information about ownership. Research to date has developed the following information. • The City has no records of the landfill. • Weld County has no records of this landfill. • The State of Colorado has a landfill of record located to the east of this site but has stated "records search turned up a solid waste permit that was issued in 1970 and appears to be for a property northeast of the park (probably where the car bodies are disposed). Solid waste permits are issued by the local governing body and known as a "certificate of designation." That time frame is just a few years after the state solid waste law was enacted. At the time the state had a standard one page form that the counties would fill out and issue as a permit for the solid waste sites that pre -dated the law Typically, the township /range information was used to identify the location of the permitted fill area. Unfortunately, this format did not dearly delineate the boundaries of the solid waste facility. No detailed operating plans could be located for this site. Thus, it is difficult to say whether the filling that occurred at the present-day Riverside Park was a westward extension of the same landfilling operation that was sanctioned by the County when it issued a certificate of designation to Earl Moffatt in 1970.' • The federal government has no records of this landfill. • Evaluation by EPA in December 2013 described the site as typical of an unregulated 1970's municipal landfill with no evidence of hazardous materials (attached EPA report). • The EPA evaluation described the landfill area as approximately 13 acres with a depth ranging from .5' to 14' containing 70,000 to 100,000 cubic yards of waste material. • The EPA evaluation detected no substantial threat to ground water of the South Platte River. • It is located immediately underneath and adjacent to a major regional public park. • It is part of an unregulated berm separating Riverside Park and other areas of east Evans from the South Platte River. • It is located adjacent to many residential structures. • Portions of the landfill are currently exposed to air and water. • Debris form the landfill covers much of the Riverside Park area. • The City has secured the entire park area and landfill with a fence • Another rise in the South Platte River may cause additional damage to the site, continuing to move the contents of the landfill through the City and downriver. • Redevelopment of Riverside Park will require removal, covering or other modification of the landfill and landfill constructed berm. Future Actions The City of is investigating a number of options ranging from no action other those minimally required to cover the exposed landfill to removal of the entire landfill. The Riverside Park redevelopment plan requires the removal of much of the landfill and landfill constructed berm. the City is also aware that any changes to the river banks and flow must be reviewed and approved by the US Army Corp of Engineers as well as other environmental clearances. City staff continues to work with the Colorado Division of Homeland Security and Emergency Management and the Colorado Department of Public Health and Environment to investigate removal and/or mitigation options. Staff plans to consult with the US Army Corp of Engineers as soon as possible. At this time the uncertainty of the landfill's future is significantly impairing future redevelopment Riverside Park and mitigation of flood risk in the eastern portions of Evans. The City is seeking technical and financial assistance to determine a course of action that meets the recovery needs of the City, the sustainable and resilient redevelopment of Riverside Park and stewardship of the South Platte River.

A site removal assessment task was initiated to assist in delineation of the exposed landfill and to determine if groundwater and soil gas contaminants exist. This document is a Final Trip Report for the CO Floods Evans Landfill site and documents worked performed at the site. This document is submitted for your review and comment. SITE DESCRIPTION The Site address is 400 Riverside Parkway, Evans, Colorado. The site is located at latitude 40.373784° and longitude -104.680076° (Attachment A). The Riverside Park property is approximately 25 acres in size (Attachment A). The property is currently owned and maintained by the city of Evans, Colorado. BACKGROUND A recent flood event uncovered a landfill on the north bank of the South Platte River, adjacent to the Riverside Park, in Evans, Colorado. The landfill is not on city, county, state, or federal records. The type and nature of the landfill is not known. The size of the landfill is not known. The landfill is currently exposed in many locations and it is not known if the site poses a threat to human health and the environment. Mr. Craig Myers U.S. EPA -2- CO Floods Evans Landfill January 14, 2013 The Riverside Park site (the Site) is located on the north bank of the South Platte River in the city of Evans, Colorado. The Site is approximately 25 acres (1,000 feet by 1,000 feet) consisting of open space, a small lake, and baseball fields. A major flood event occurred September 11 — September 13, 2013 along the Front Range of Colorado causing record flooding. The South Platte River overflowed its banks along large portions of the river, including through the city of Evans, Colorado. The South Platte River stayed above flood stage through September 19, 2013 in the city of Evans (Evans 2013). As a result of the flooding, erosion through the site uncovered an unknown landfill two to four feet below ground surface. New channels were cut through the cap and into the landfill debris and the debris was spread across the site. Material identified includes that typical of a municipal solid waste landfill, including construction and demolition debris. Items typical of an unregulated landfill were also identified, including tires, deteriorated 55 -gallon drums, and engine oil filters. Pre- 1970's tires and the lack of plastic bottles suggest that the landfill is pre 1980. Medical waste (syringes, IV drip bottles) were also found on the site and as debris in the landfill material. The extent and depth of the landfill is not known (Federal Emergency Management Agency [FEMA] DR 4145 2013). City officials have limited knowledge of the site and the landfill. The Riverside Park area was purchased as a redevelopment project by the city in 1991 from Snyder Oil Company. The city, state, and county do not have a record of a landfill on the site. U.S. EPA records do not report a landfill on the site (Evans 2013). SITE ACTIVITIES Geophysical Investigation WESTON contracted Zapata, Inc. to perform an Electomagnetic Induction (EMI) survey on December 3 and 4, 2013. START contractor Nathan Williams was on site with the Zapata crew. The EMI survey data were acquired with a Geonics, Ltd. EM -31 ground conductivity meter. The initial EM -31 survey allowed for a large area to be investigated prior to discrete excavation work. Interpretation of the EM -31 data suggested the presence of conductive material (metallic material or conductive clay landfill cap material) paralleling the South Platte River with lower conductive material (sandy soil) on the west. Two small highly conductive areas were also identified and slated for further investigation. START and the Zapata crew demobilized from the site on December 4, 2013. The EMI survey report is provided in Attachment B.

Mr. Craig Myers U.S. EPA -3- CO Floods Evans Landfill January 14, 2013 Direct -Push Soil Gas and Groundwater Investigation START staff members Nathan Williams, Bryan Williams and Megan Adamczyk mobilized to the site on December 10, 2013 and met EPA On -Scene Coordinator (OSC) Joyce Ackerman. The EPA Geoprobe 0 was used by START staff to probe four soil gas locations and install three groundwater wells. Sample locations are provided in Attachment A, Figure 2. Soil gas samples were collected on December 10 and 11, 2013. The GeoprobeDual Tube direct push system was first used to collect subsurface soil samples in the suspect high conductivity areas identified with the EMI Survey. Core logs are provided in Attachment F. Garbage was encountered in the four locations suspected to be in the landfill at 4 — 8 feet (ft.) below ground surface (bgs). No garbage was identified in the background sample, located west of the suspected landfill in an area identified as a low conductivity area in the EMI survey. Sample locations are provided in Attachment A, Figure 2, and listed in Table A below: Table A.

The Geoprobewas moved 40 feet away from the soil core location. The Geoprobe system allows for a 1.25 inch rod string to be pushed to a desired depth and a gas sample to be collected with a vacuum tight seal from the desired depth. The rod string was pushed to the bottom of the garbage and then the rod string was pulled back a foot to expose an air space within the garbage zone. Sample depths are presented in Table A and on the core logs in Attachment F. Generally, soil gas samples were collected between 4.5 and 8 feet bgs. The soil gas grab samples were collected with 6 -liter Summa canisters and were collected in accordance with U.S. EPA Soil Gas sampling Standard Operating procedures (SOP) (EPA 1996) and the Geoprobe O Soil Gas Sampling — PRT System Operation SOP (Geoprobe 2013).

Mr. Craig Myers U.S. EPA -4- CO Floods Evans Landfill January 14, 2013 samples were analyzed by Method TO -15 for Volatile Organic Compounds (VOC) and Methane. Soil gas samples were shipped to the lab on 12/11/13. Samples were shipped on December 11, 2013 to: ALS Laboratory 2655 Park Center Drive, Ste. A Simi Valley, California 93065 Temporary groundwater wells were installed on December 11, 2013. Two wells were installed into the known landfill at the northern and southern extents (Figure 2; ELGW02 and ELGW03, respectively). Core logs and well construction information is provided in Attachment F. A background well (ELGW0 1) was installed south and west of the presumed extent of the landfill. Garbage material was generally sitting above the water table. Groundwater appeared to be contained within coarse river sands below the bottom of the garbage. Garbage in the soil cores was generally identified between 4 and 8 feet bgs. Groundwater was identified at 8 to 13 feet bgs in the soil cores. No garbage was identified in the background well location. Core logs are provided in Attachment F and visible in the Photolog (Attachment E). Groundwater samples were collected for VOCs, Semivolatile Organic Compounds (SVOCs) and Target Analyte Metals (TAT) total metals. Samples were delivered December 12, 2013 to: Accutest Laboratories 4036 Youngfield Street Wheat Ridge, Co 80033 Landfill Delineation Excavation work was performed by Environmental Restoration (ER) with guidance from START and the EPA OSC on December 10 - 12, 2013. An excavator provided by ER was used to trench and dig test pit areas of interest identified by the EMI survey. Test pit locations and descriptions are provided on Figure 2. Thirty-eight test pits were excavated across the site (Figure 3). In general, areas of high conductivity identified by the EMI survey were areas of dense household debris (glass, plastic, cans, bottles, yard clippings, small metal, etc.) and light commercial debris (wood, metal, electrical conduit, etc.). Garbage was generally found in the areas of high conductivity under a thin layer (0 — 4 feet) of sandy soil. Location of the garbage mimicked the high conductivity areas identified in the geophysical survey. Landfill material also mimicked the topography of the long uneven ridge of material found paralleling the South Platte River. The western boundary of the garbage appeared to be lined with concrete debris. Garbage appeared to extend to the northern property boundary, except where recent flooding had created a channel. (Test pit 27). No heavy industrial debris or stockpiles of 55 -gallon drums were P:\20408 EPA Region 8 START IV\TDDs\0001-1312-04 CO Floods Evans Landfill\Deliverables\Trip Report\FinalReport\COEvans Trip Report_Final l .doc This document was prepared by Weston Solutions, Inc., expressly for U.S. EPA.

Mr. Craig Myers U.S. EPA -5- CO Floods Evans Landfill January 14, 2013 identified in the 38 test pits. Photos are provided in Attachment E. Photo locations are provided on Figure 3. Pipelines are visible at the northern end of the site and on the east side of the suspected landfill, adjacent to the South Platte River. The pipelines are associated with active production wells and were avoided. Garbage was visible on the edge of the South Platte River. The western bank of the river was armored with concrete blocks and old automobiles were visible in the sands on the northern end of the suspected landfill. Excavation work indicates that the landfill encompasses approximately 13 acres. Thicknesses of garbage varied across the site with thicknesses in the suspected landfill area up to 14 feet thick. Areas were calculated based on garbage thicknesses in the test pits and extrapolated across the site. The total area of land with garbage is approximately 13 acres. The average thickness is 7.2 feet thick. A conservative estimate would be that the volume of garbage is greater than 77,000 cubic yards and less than 100,000 cubic yards. Test pit locations are provided on Figure 2. An interpolation of approximate thicknesses of garbage material is provided in Figure 4. EPA, START and ER demobilized from the site at 1600 hours on December 12, 2013 after site cleanup and final equipment decontamination. ANALYTICAL RESULTS Groundwater All data were verified by START subcontractor Techlaw, Inc. After review of the data reported by Accutest Laboratories, data were found to be acceptable for use in this evaluation. Samples were analyzed at Accutest Laboratories with a NELAP approved quality assurance program using SW 846 8260B Volatile Organic Compounds by GC/MS, SW 846 8270C SVOCs by GC/MS, and SW 846 6010C (Metals) Inductively Coupled Plasma -Atomic Emission Spectrometry. The quality control measures are acceptable for the results produced by methods 8260B and 8270C due to the fact that there were non -detects for all analytes with regards to both methods. The quality control measures for 6010C were also considered acceptable; the only non-conformance that occurred was the serial dilution which is considered a non -issue due to low initial concentrations of sample analytes. Sample analysis produced multiple results with regards to SW 846 6010C and should be considered valid due to lack of data flags and acceptable quality control measures. Further review of the data is needed to determine compounds of interest. Groundwater results tables are provided in Attachment C. The laboratory analytic reports are provided in Attachment D. Three groundwater samples (and one duplicate) were collected. Two groundwater samples were collected in the suspected landfill and one background sample was P:\20408 EPA Region 8 START IV\TDDs\0001-1312-04 CO Floods Evans Landfill\Deliverables\Trip Report\FinalReport\COEvans Trip Report_Final l .doc This document was prepared by Weston Solutions, Inc., expressly for U.S. EPA. It shall not be released or disclosed in whole or in part without the express, written permission of U.S. EPA. Mr. Craig Myers U.S. EPA -6- CO Floods Evans Landfill January 14, 2013 collected 800 feet west of the suspected landfill. Data did not indicate elevated VOCs or SVOCs in the two samples located within the suspected landfill or the background water sample. Metals concentrations in the two suspect landfill groundwater wells were not above three times the background sample concentrations, indicating that the metals values are not statistically significant. Soil Gas Sampling All data were verified by START subcontractor TechLaw, Inc. After review of the data reported by ALS Laboratory, data were found to be acceptable for use in this evaluation. Samples were analyzed at ALS Laboratory in accordance with a NELAP and DOD-ELAP approved quality assurance program using modified EPA method 3C for methane and EPA Method TO -15 for determination of Toxic Organic Compounds in Ambient Air. All quality control measures were found to be acceptable, analysis of the method blank was non -detect for all analytes as well as acceptable recoveries in the laboratory spike sample. Sample analysis produced multiple compounds present in many of the samples analyzed; further review would be needed to determine compounds of interest. All results should be considered valid due to acceptable quality control measures and lack of data flags present. Soil gas analytic results tables are provided in Attachment C. The results of the soil gas sampling are consistent with what is to be expected from an older, unregulated landfill. In general, landfill gas is approximately forty to sixty percent methane, with the remainder being mostly carbon dioxide (EPA, 1995). Methane was identified in three of the samples (ELSG03, ELSG03D, and ELSG04) in the central portion of the landfill. Methane values ranged from 32 — 42% in the three samples collected in the central portion of the landfill. VOC compounds were identified in the samples collected in the suspected landfill. Most of these other VOC contaminants are known as "non -methane organic compounds" (NMOCs). The U.S. EPA has identified ninety-four non -methane organic compounds, including toxic contaminants benzene, toluene, chloroform, and vinyl chloride as NMOCs in landfill gas (EPA 1995). NMOCs were identified in the three samples with elevated methane concentrations. The NMOCs usually make up less than one to two percent of landfill gas (EPA 1995). Data indicate the NMOCs occurred at concentrations less than 0.1 percent of the total landfill gas collected in the samples with highest concentrations within the landfill. Analytes were identified in the background sample, but at concentrations orders of magnitude lower than in the soil gas samples collected in the landfill. The results were also compared to screening levels provided in the OSWER Draft Guidance for Evaluating the Vapor Intrusion to Indoor Air Pathway from Groundwater and Soils (EPA 2002).

It shall not be released or disclosed in whole or in part without the express, written permission of U.S. EPA. Mr. Craig Myers U.S. EPA -7- CO Floods Evans Landfill January 14, 2013 An attenuation factor is applied to screening levels of the target indoor air analytes to account for reduction of concentrations from soil gas to indoor air that building materials (i.e. concrete foundation, etc.) would provide. Although no structures or barriers are present at the site, the screening levels provide guidance for comparison. Sample locations ELSG03 and ELSG04 were in exceedance for 1,2,4-Trimethylbenzene, 1,3,5-Trimethylbenzene, Napthalene, and Trichloroethene. ELSG03 also had exceedances for Toluene, and Vinyl Chloride. ELSG04 also had exceedances for Chlorobenzene and cis -1, 2-Dichloroethene. Although exceedances do exist, an exposure pathway is not present. The threat of soil gas entering indoor air is not a concern at present. SUMMARY The December 2013 assessment work allowed for the delineation and characterization of the suspected landfill. Excavation work at the site allowed for the boundary and thickness of garbage at the site to be determined. Based on this evaluation, the suspect landfill is approximately 13 acres in extent and averages approximately 7.2 ft. thick. Groundwater and soil gas samples were collected to evaluate the potential for exposure to hazardous constituents. Groundwater samples did not identify VOCs or SVOCs. TAL metals were not identified above three times the concentration of the background sample. Although minor exceedances of OSWER screening levels did exist in the soil gas samples, the exposure pathway of soil gas to indoor air does not exist at the site. Further review of compounds of interest identified in the soil gas may provide additional site characterization. Sincerely, Weston Solutions, Inc. Nathan D.

Introduction On December 3 and 4, 2013, Zapata Incorporated (ZAPATA) conducted an Electromagnetic Induction (EMI) survey at a site located in the city of Evans, Colorado along the north bank of the South Platte River. The site was the location of a former landfill that had been closed and possibly clay capped. It was generally an open grass field with occasional wooded areas. Erosion from recent flooding of the South Platte has exposed trash in several areas. The survey area was determined by Weston and identified to ZAPATA' s field crew upon arrival at the site. The scope of the EMI survey was to delineate the boundary of the former landfill and to identify areas within the landfill that contain significant metal debris. Data Acquisition The EMI data were acquired using a Geonics Ltd, EM31 ground conductivity meter. The EM31 is a frequency domain EMI instrument which measures the quadrature phase and the inphase components of an induced magnetic field. At low induction numbers, the quadrature phase is related to the bulk conductivity of the soils beneath the instrument. The inphase component measures the magnetic susceptibility of the soils, and is sensitive to metal content within the soils. The depth of investigation of the EM31 is approximately 18 feet bgs (below ground surface). The EM31 was mounted on a non-metallic trailer in vertical dipole orientation and towed using a small UTV. A GPS antenna was mounted over the EM31 console and RTK- DGPS was used to record the position of the data simultaneously with the EM31 data on an Allegro data logger running Trackmaker3l software written by Geomar Software. The data rate on the EM31 and GPS was 5 Hz and 2 Hz, respectively. GPS data were recorded using a NMEA GGA string. The GPS base and rover system was a Trimble survey grade RTK GPS. An instrument latency test was recorded over a visible metal plate in place in a nearby concrete sidewalk. 301 Commercial Road 0 Suite B 0 Golden CO 80401 800.395.4295 C www.zapatainc.com.com Mr. Nathan Williams 12/9/2013 Page 2 of 3 EM31 data were recorded along profiles spaced nominally 15 ft apart in a northeast -southwest direction parallel to the South Platte River. A second set of data were recorded along northwest - southeast profiles at nominal 50 -ft spacing. Surface erosion, mud and trees prevented data acquisition in some areas. Data Processing The EM31 field data were downloaded from the Allegro data logger. These data were sent to ZAPATA' s Golden office at the end of each day to check for coverage and data quality and final processing of contour maps. The EM31 data were positioned using the GPS data within Trackmaker31 and exported as a columnar ascii *.xyz file. This file was imported into Geosoft's Oasis Montaj for gridding and display. Preliminary color contour maps were generated each morning following data collection and sent to Weston. ZAPATA established a survey GPS base location using an instantaneous position solution. This resulted in a position that was not absolutely correct but within five feet of its true location. Base station position measurements were stacked during the first day and submitted to the National Geodetic Service (NGS) OPUS website for accurate positioning. This resulted in a position for the base location accurate to within 0.25 meters. All data positioning were adjusted using the position solution provided by OPUS. Table 1 presents the OPUS corrected GPS base position. Table 1: Common Survey Tie Points Survey Control- OPUS location UTM 13N Survey Control- OPUS location Lat/Long Control Point ID Easting (m) Northing (m) Latitude (DMS) Longitude (DMS) BASE 527005.8 4469093.7 40 22' 19.14132" -104 40' 54.80663" The EM31 data, with positioning, were re-gridded and plotted in Geosoft Oasis. A latency correction of 0.8 seconds was applied to the data as determined from the latency test files collected at the beginning and end of each day's survey. This correction improves data positioning accuracy and removes the "herringbone" appearance that can occur over linear anomalies, such as buried pipes, culverts and other linear features. Results The results of the EM31 survey are presented on annotated color contour maps overlaid on aerial photographs. Figure 1 (Ground Conductivity) and Figure 2 (Inphase Component) present these results. The EM31 ground conductivity map (Figure 1) best displays the boundary of the landfill in those areas where a clay cap was apparently placed over at least a portion of the landfill. Clay material is generally electrically conductive and results in a high bulk conductivity which is shown as a red/pink area indicating conductivities > 50 mS/m (milliSiemens/meter). Background values, observed off the landfill, were in the 20-30 mS/m range. It is apparent from observations in the field that parts of the landfill are not covered with a clay cap but instead are covered with sand. Those areas generally show conductivity values less than 16 mS/m. Field observations made during data collection indicated the presence of both areas of trash which are covered with sand and areas in which trash was exposed at the surface. Due to safety concerns 301 Commercial Road 0 Suite B 0 Golden CO 80401 800.395.4295 C www.zapatainc.com.com Mr. Nathan Williams 12/9/2013 Page 3 of 3 most of the areas with large amounts of exposed trash were not surveyed with the EM3 1 array. The surface trash and sand deposits may be the result of recent flooding. The easternmost part of the survey area contains areas of hilly terrain which may be indicative of trash which has settled over time. These areas are indicated on Figure 1 as having low conductivities which again may be indicative of a sandy material overlay. Figure 2 presents the EM31 inphase data. Inphase data are more sensitive to metal than the ground conductivity data and are useful in identifying buried metallic objects. The inphase results generally mimic the ground conductivity data but are not as smooth due to distortion from numerous metal objects within the ground. This data suggest that most of the survey area contains metallic debris both above and below ground surface. Numerous metallic objects were observed on the ground surface during the surveying. These high metal areas are indicated by the numerous adjacent highs and lows in the data giving the figure a "mottled" appearance. There is a pronounced presence of buried metallic debris along the river boundary of the survey area and near the exposed trash pit in the vicinity of the solar array. Summary and Conclusions Approximately 25 acres were surveyed using an EM31 Ground Conductivity System. Ground conductivity measurements indicate that a clay cap may be in place over portions of the landfill. These areas are delineated by the red/pink contours presented on Figure 1. The low conductivity areas are interpreted as sandy soils. This interpretation is supported by direct observation of the survey area and observations of the exposed trash near the solar array which is overlaid by these sandy soils. Inphase data, presented on Figure 2, indicate that the entire survey area contains metallic objects both on the surface and below ground. This interpretation is supported by the observations made during the survey of the area. The inphase data indicate a high concentration of metallic objects along the boundary of the river boundary of the survey area and the area near the solar array. The recent flooding in the summer of 2013 likely displaced some of the landfill trash and may have deposited sand and trash from areas upstream, not included in the survey area.

Bunker Ct, Suite 500 Vernon Hills, IL 60061 RE: Evans Landfill / 20408.012.001.0081.00 Dear Tonya: Enclosed are the results of the samples submitted to our laboratory on December 12, 2013. For your reference, these analyses have been assigned our service request number P1305508. All analyses were performed according to our laboratory's NELAP and DoD-ELAP-approved quality assurance program. The test results meet requirements of the current NELAP and DoD-ELAP standards, where applicable, and except as noted in the laboratory case narrative provided. For a specific list of NELAP and DoD-ELAP-accredited analytes, refer to the certifications section at www.alsglobal.com. Results are intended to be considered in their entirety and apply only to the samples analyzed and reported herein. If you have any questions, please call me at (805) 526-7161.

Service Request No: P1305508 Project: Evans Landfill / 20408.012.001.0081.00 CASE NARRATIVE The samples were received intact under chain of custody on December 12, 2013 and were stored in accordance with the analytical method requirements. Please refer to the sample acceptance check form for additional information. The results reported herein are applicable only to the condition of the samples at the time of sample receipt. Methane Analysis The samples were analyzed for methane according to modified EPA Method 3C (single injection) using a gas chromatograph equipped with a thermal conductivity detector (TCD). This procedure is described in laboratory SOP VOA-EPA3C. This method is not included on the laboratory's NELAP or AIHA-LAP scope of accreditation. Volatile Organic Compound Analysis The samples were also analyzed for volatile organic compounds in accordance with EPA Method TO -15 from the Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air, Second Edition (EPA/625/R-96/01 0b), January, 1999. This procedure is described in laboratory SOP VOA-TO1 5. The analytical system was comprised of a gas chromatograph / mass spectrometer (GC/MS) interfaced to a whole -air preconcentrator. The method was modified to include the use of helium as a diluent gas in place of zero -grade air for canister pressurization. When necessary, analytical sample volumes were adjusted by a correction factor for canisters pressurized with helium. A summary sheet has been included listing the affected samples. This method is not included on the laboratory's AIHA-LAP scope of accreditation. Any analyzes flagged with an X are not included on the laboratory's NELAP or DoD-ELAP scope of accreditation. The Summa canisters were cleaned, prior to sampling, down to the method reporting limit (MRL) reported for this project. Please note, projects which require reporting below the MRL could have results between the MRL and method detection limit (MDL) that are biased high. The results of analyses are given in the attached laboratory report. All results are intended to be considered in their entirety, and ALS Environmental (ALS) is not responsible for utilization of less than the complete report. Use of ALS Environmental (ALS)'s Name.

From my observations they ;pear to be violating 40a18- 46 of the Colo. statues which'T)rome hibits aum-0,ing litter in ny waters of the state. Subsection B of the statues states that the state, subdivisions ect. . can2 ae ignate areas where dumping of trash is permitted, Eg but this would not in elude the rivers or water courses of the state. The Weld County Landfill is operated as most landfills are, the trash is brought in to the dump. area it Is then compacted with track type machines then is covered, the problem with this opera ation is that the dump area lies on the bank of tie South Platte river and the tra h after compaction is covered with river sand, as the dum area is located in the flood loism plain of the Platte during high water and even to some extent during normal flow,the water washes the sand away from the trash and the trash washes into o the river. I have observed and photographed this t 1 .g place. Evidence of litter can be found almost anyplace down stream from this dump that a person would care to look. If the garbage from this dump is going to end ypt eriver can see no reason for the operation of this land fib J - t would be auch cheaper for every one to just dump the garbage right into ties' tij Q If can be of help to y o u at any time just let me know.

Box 1227 Greeley, Colorado 80631 Dear Dr. Cleaver: As a result of our inspection on April 21, 1970 of Mr. Earl Moffat' s sanitary landfill near Evans, Colorado, please be advised of the following: 1. The protective dike designed to protect the site from high flood water should not contain solid waste excepting nondegradable material such ason re to , etc. the landfill operation mu s t be carried on only i th in the inner limits of the dike. Compacted material if placed within the dike itself is subject to river erosion and subsequent deposit directly in the river channel,_ there- by causing water pollution. . It iappears that a major portion of the fill material at this particular site is obtained from deposit within thi the lai river channel and flood plain. Because of the limited accessibility of this cover material during.times times f high water it is important that alternate sites be available and useable so as to provide satisfactory sanitary landfill practices at all times.
