Executive Summary A Phase II Environmental Site Assessment (ESA) was conducted at the proposed location of the Olde Town Station (OTS), part of the Regional Transportation District’s (RTD’s) FasTracks Gold Line Corridor. Walsh Environmental Scientists and Engineers (WALSH) completed the Phase II ESA under RTD Contract No. 15-DO-037. This Phase II ESA of RTD’s proposed OTS site included investigation at two properties included in the station footprint: the Arvada Urban Renewal property and the North JeffCo Metro Parks and Recreation property. Right-of- entry (ROE) was not obtained for two other properties within the planned footprint (First National Bank and Sullivan One), which were not investigated. The Phase II ESA included sampling, field screening and laboratory analysis of surface soil samples collected at 15 locations, subsurface soil samples from 11 locations, and groundwater samples from 7 locations. Groundwater samples did not contain organic contaminants at concentrations exceeding Colorado Groundwater Standards (CGWS). Concentrations of manganese exceeded CGWS secondary standards under Table 2 (taste and odor criteria) in five borings including one (AUR-01) on the Arvada Urban Renewal parcel and four (NJM-01, NJM-05, NJM-07, and NJM-08) on the North Jeffco Metro parcel. Manganese concentrations ranged from 600-1900 micrograms per liter (ug/l) versus the CGWS Table 2 standard of 50 ug/l. The concentration of iron exceeded CGWS secondary standards under Table 2 (taste and odor criteria) in one boring (NJM-8) at 980 ug/l versus the CGWS Table 2 standard of 300 ug/l. These concentrations of manganese and iron are not considered environmentally significant since both are naturally occurring and there is no current or planned consumptive use of groundwater. Concentrations of lead in soil exceeded CSEV criteria at five locations. Three samples (NJM-12, NJM-13, and NJM-14) had lead concentrations exceeding the CSEV worker protection standard of 800 milligrams per kilogram (mg/kg) with lead concentrations ranging from 1,200 to7,600 mg/kg. These samples were collected from the North Jeffco Metro property adjacent to the shooting range, near windows or vents, and most likely represent airborne lead deposition from the range. Visible lead fragments (spent ammunition) were observed on exterior vent/window ledges on the outside surface of the range building.


Olde Town Station Phase II ESA 1-21-10.docx vii

Two other soil samples NJM-2 and NJM-10 had lead concentrations equaling or exceeding the CSEV standard for residential exposure of 400 mg/kg. These samples were also collected at locations close to the shooting range. Arsenic concentrations exceeded the CSEV standard of 1.6 mg/kg for worker protection at ten locations. However, arsenic commonly occurs naturally at concentrations above the CSEV. Arsenic concentrations ranged from 2.4 mg/kg to 30 mg/kg at NJM-4. The maximum arsenic concentration of 30 mg/kg at NJM-4 was the only sample which exceeded the 25 mg/kg standard that CDPHE considers the maximum background arsenic concentration for the urban metropolitan Denver area. Soil sample analyses showed exceedence of residential exposure Colorado Soil Evaluation Values (CSEV) for three semi-volatile polycyclic aromatic hydrocarbons (PAHs), benzo[a]pyrene, benzo[b]fluoranthene and dibenzo [a,h]anthracene. All PAH concentrations were below CSEV worker protection concentrations, which would be likely be the applicable standard for the OTS construction since no residential land-use is planned at the OTS site. No suspect asbestos-containing material (ACM) was observed, consequently no samples were collected for ACM analyses. The interior of the shooting range structure was not sampled. Following decommissioning and decontamination of the firing range and surrounding soils, confirmation sampling of the range, building materials and surrounding soils is recommended prior to RTD taking possession of the property. Limitations The conclusions presented in this report were developed from the review of information developed during the Phase I and Phase II site investigations, field observations, measurements, and laboratory analyses. The conclusions pertain only to the properties investigated because ROE was not obtained from two other properties within the planned station footprint. In addition, physical constraints, such as equipment, vehicles, underground utilities, and property boundaries limited soil and groundwater sampling areas. Subsurface conditions may vary at locations and times other than those tested, and practicality prohibits the investigation of all soil and groundwater. If additional information concerning site environmental conditions becomes available, the conclusions presented in this report will not be considered valid unless this information is reviewed and the conclusions of this report are modified and approved in writing by WALSH.

Phase II Environmental Site Assessment RTD FasTracks Gold Line Corridor

Olde Town Station

1 INTRODUCTION

A Phase II Environmental Site Assessment (ESA) was conducted at the proposed location of the Olde Town Station (OTS), part of the Regional Transportation District’s (RTD’s) FasTracks Gold Line Corridor. Walsh Environmental Scientists and Engineers (WALSH) completed the Phase II ESA under RTD Contract No. 15-DO-037.

2 PROBLEM DEFINITION

RTD’s FasTracks Program plans to acquire property for the construction of the Gold Line OTS at a location directly west of Wadsworth Boulevard in Arvada, Colorado. RTD’s plan for the station calls for the acquisition of parcels of land north and south of the Burlington Northern Santa Fe Railroad (BNSF) rail line, which parallels Grandview Avenue. The limits of construction of the proposed OTS site (see Figure 1) include properties currently owned and/or occupied by Sullivan One LLC, First National Bank, Arvada Urban Renewal Authority, and North Jeffco Parks and Recreation District. The Phase II ESA included only the properties for which RTD had obtained right-of-entry (ROE) within the proposed construction footprint shown on Figure 1. The objective of this Phase II ESA is to provide information concerning the possible presence of hazardous substances in soils and groundwater at the proposed OTS. The findings are needed to identify and initially characterize possible soil and/or groundwater contamination prior to RTD’s acquisition of these properties. The presence, at the OTS site, of hazardous substances in soil at concentrations exceeding the Colorado Soil Evaluation Values (CSEV, CDPHE 2007) or in groundwater at concentrations exceeding the Colorado Basic Standards for Groundwater (CGWS, CDPHE 2009) may make it necessary for RTD to further characterize the extent and nature of that contamination, and/or to prepare Materials Management Plans and Health and Safety Plans (HASPs) prior to proposed construction. Significant contamination may require RTD to conduct remedial actions to comply with environmental regulations and/or protect worker and public health and safety. This Sampling and Analysis Plan/Quality Assurance Project Plan (SAP/QAPP) was prepared based on findings of Phase I ESAs that RTD has obtained for each of the Olde Town properties (WALSH 2009a-d). The Phase I ESAs included site inspections, interviews, review of environmental database reports, and historical records. Access to the interior of an indoor firing range located on North Jeffco Parks and Recreation District property was not obtained.

The Phase I ESAs for the OTS parcels concluded there were several significant sources of possible contamination from historic uses of the property. The area within and immediately upgradient of the proposed OTS construction footprint has a long and diverse history of industrial and railroad use, which includes the transport and storage of hazardous materials and petroleum products. Recognized environmental conditions (RECs) that have been identified on the subject properties to be acquired for the OTS include soil and groundwater contamination associated with leaking underground storage tanks (LUSTs), documented lead contamination within bullet catch boxes inside of the indoor firing range, as well as potential contamination derived from the cleaning and disposal of firing range waste, and possible lead contamination within the ventilation system. In addition to the above mentioned RECs, multiple soil piles of unknown origin exist on the site and were investigated for contamination. Management plans or remedial actions may be required for handling and disposal of building components, contaminated soils and groundwater during construction, and to control possible health risks to construction workers and the public and risks of exposure to the public at the site. There is currently no human consumption of groundwater at the site, and none of the development plans suggest use of groundwater for drinking water. The sampling and analysis activities covered by this SAP/QAPP include soil and groundwater sampling at various locations within the project to evaluate whether any environmental conditions may require Materials Management Plans or remedial actions for construction activities and/or for RTD’s proposed land use. The SAP/QAPP is based on the conclusions and recommendations of the Phase I ESAs that were prepared by WALSH (2009) for each parcel within the proposed construction footprint. Proposed sampling and analysis activities, presented in this SAP/QAPP are based on evaluations of Phase I ESA findings, including historical evidence, potential contaminants of concern, a conceptual site model, and possible exposure pathways.

3 SITE DESCRIPTION

3.1 Site Location and Description

This Phase II ESA of RTD’s proposed Olde Town site included activities at two of four properties located along the FasTracks Gold Line corridor, which parallels Union Pacific Railroad right-of-way (ROW) north of I-70 in Denver, Colorado. The four main properties include (from west to east) the First National Bank of Arvada site at 7530 Grandview Avenue; the Arvada Urban Renewal Authority site at 7450 Grandview Avenue; the Sullivan One, LLC site at 5580 Vance Street; and the North JeffCo Metro Parks & Recreation District site at 7307 West 56th Place. No ROE was obtained for the First National Bank or Sullivan properties, consequently these properties were not physically investigated. All of the properties have addresses listed as Arvada, Colorado.



Detailed site descriptions of the subject properties and results of interviews with current owners and occupants are presented in the Phase I ESAs for the four properties (WALSH 2009). The total land area of the four properties is estimated to be approximately 2.2 acres, including from west to east:

First National Bank of Arvada: one parcel, total area, 0.11 acres (No ROE). Arvada Urban Renewal Authority: one parcel, area, 0.49 acres. Sullivan One, LLC: one parcel, total area, 1.01 acres (No ROE). North JeffCo Metro Park & Recreation District: one parcel, total area 0.57 acres.

3.2 Physical Setting

3.2.1 Topography

The Site lies within the United States Geological Survey (USGS) 1:24,000 Arvada, CO topographic quadrangle at an elevation range of approximately 5,295 to 5,300 feet above mean sea level. The topography in the vicinity of the site slopes generally to the east (USGS 1990).

3.2.2 Regional and Site Geology

The site lies within the Denver Basin, periodically referred to as the Denver-Julesburg Basin (after Julesburg, Colorado), or the D-J Basin, a geologic structural basin centered in eastern Colorado in the United States, but extending into southeast Wyoming, western Nebraska, and western Kansas. It underlies the Denver-Aurora Metropolitan Area on the eastern side of the Rocky Mountains. The basin consists of a large syncline of stratified Paelozoic and Mesozic sedimentary rock layers, running north to south along the east side of the Front Range from the vicinity of Pueblo northward to Wyoming. The sag is deepest near Denver, where it reaches a depth of approximately 13,000 feet below ground surface (bgs). The basin is strongly asymmetric: the Dakota Sandstone outcrops in a “hog-back” ridge near Morrison a few miles west of Denver, reaches its maximum depth beneath Denver, then ascends very gradually to its eastern outcrop in central Kansas.

The late Cretaceous-early Paleocene Denver Formation is characterized by fine-grained silt and clay fluvial deposits. Lenticular sandstones are present locally, encased in fine-grained deposits. In the early Paleocene, regional uplift led to a period of non-deposition and erosion and the exposed Denver Formation was eroded down to a relatively flat surface by late Paleocene time. The overlying Dawson Formation was deposited in a meandering stream environment lateral to the newly uplifted Front Range. Early in Dawson time, streams cut into the upper portions of the exposed Denver Formation as they crossed the site and lower Dawson fluvial material was deposited. A period of non-



deposition and erosion occurred throughout the Pliocene. Pleistocene and recent streams have cut into exposed Dawson and Denver formations and deposited sequences of alluvial material.

Younger (Quaternary and Tertiary) geologic units generally are less consolidated than the older units and can form more permeable aquifers. Older (Early Paleozoic and Precambrian) geologic units generally are crystalline or well consolidated and do not readily yield water except from faults, fractures, or solution openings. Locally, the Site falls within the Gravels and alluviums geologic unit. This unit is of Quaternary age and consists primarily of gravel, sand, silt, and clay deposits. The Gravels and alluviums unit is underlain by the Denver and Arapahoe Formations of Tertiary-Cretaceous age. These two formations, which share a mapping unit, consist primarily of sandstone, but may also contain mudstone, claystone, and conglomerate (Tweto 1979). The United States Department of Agriculture (USDA) Natural Resources Conservation Service web soil survey (http://websoilsurvey.ncrs.usda.gov/) was queried on September 14, 2009 to identify the soil types mapped at the Site. The majority of the Site is mapped as Alda-Niwot complex. The typical profile for this unit is loam from 0 to 11 inches, stratified loamy sand to loam from 11 to 38 inches, and very gravelly loamy sand from 38 to 60 inches. The northern edge of the Site is mapped as loamy Ustic Torriorthents. The typical profile for this unit is loam from 0 to 3 inches, and loam, clay loam and sandy clay loam from 3 to 60 inches. Borehole logs characterized unconsolidated alluvium consisting of near surface silty clays over silty sands and gravely sands at the water table. Siltstone bedrock was encountered at depths of 12 to 22 feet bgs.

3.2.3 Hydrology

Based on the topography, surface water in the vicinity of the site appears to flow toward the east. Primary surface water features in the vicinity of the site include Ralston Creek, approximately 2,000 feet north of the site and Clear Creek, approximately 1 mile south of the site. Ralston Creek flows into Clear Creek approximately 1.25 miles east of the site. Stormwater from the site is directed downhill to a sewer grate in the southeast corner of the property. Using City of Arvada storm sewer maps, the subsurface flow was traced eastward to the edge of Arvada, approximately ¼ mile west of the confluence of Ralston and Clear Creeks. Borehole logs indicated groundwater in unconsolidated sediments in the vicinity of the site ranging from 8 to11 feet bgs. Groundwater may also be present in bedrock aquifers under the site.



4 POTENTIAL ENVIRONMENTAL CONCERNS AND EXPOSURE PATHWAYS

4.1 Potential Environmental Concerns Several potential environmental concerns were identified in the Phase I ESAs (WALSH 2009) for the four properties in the OTS site. The objective of this Phase II ESA is to provide information concerning the possible presence of hazardous substances in soils and groundwater at the proposed OTS. The findings are needed to identify and initially characterize possible soil and/or groundwater contamination prior to RTD’s acquisition of this property. The presence at the OTS site of hazardous substances in soil at concentrations exceeding the CSEV (CDPHE 2007) or in groundwater at concentrations exceeding the CGWS (CDPHE 2009) may make it necessary for RTD to further characterize the extent and nature of that contamination, and/or to prepare Materials Management Plans and HASPs for its proposed construction. Significant contamination may require RTD to conduct remedial actions to comply with environmental regulations and/or protect worker and public health and safety. The existence of a contaminant in soil or groundwater at concentrations exceeding a CSEV or Colorado groundwater standard does not necessarily mean that additional characterization, a Materials Management Plan, or a remedial action, will be required. An evaluation of potential risks and exposure pathways would be required to determine if such actions are required. Discussions of the approach to address potential environmental concerns, including a conceptual site model and dynamic work strategies for the Phase II ESA, are presented in this SAP/QAPP. The First National Bank of Arvada site, 7530 Grandview Avenue The First National Bank of Arvada property is located within the Arvada Downtown Historic District at 7530 Grandview Avenue. The property consists of one parcel of land totaling 0.11 acres, according to the Denver County Assessor’s Office database. The site consists of an asphalt lot used for parking and a small building used to house an Automated Teller Machine. The site consists of the portion of Parcel 39-114-19-005 that is within the “station limits of construction.” The potential for benzene and petroleum hydrocarbon contamination in groundwater exists at the site. The most probable source is the former Fina Gas Station at the northeast intersection of Yukon Street and Grandview Avenue. Several other LUST events and historic unregistered underground storage tanks (USTs) are also upgradient from the property. No ROE was available for this property.



Arvada Urban Renewal Authority site, 7450 Grandview Avenue Arvada Urban Renewal Authority site, located at 7450 Grandview Avenue, consists of one parcel of land, totaling 0.49 acres. No RECs were identified during the Phase I; however, two apparent monitoring wells were observed in the asphalt parking lot. The owner was not able to provide information pertaining to these wells. Permission was be requested from the owner of the wells to collect groundwater samples from the wells for laboratory analysis. Sullivan One, LLC site, 5580 Vance Street Sullivan One, LLC site, located at 5580 Vance Street, consists of 1 parcel of land, totaling 1.01 acres. No RECs were identified during the Phase I; however, a pile of asphalt debris was observed in the northeast corner of the site, and access was not granted to the site and no interviews were conducted with persons knowledgeable about the history of the site, which presents a significant data gap. No ROE was available. North JeffCo Metro Park & Recreation District site, 7307 West 56th Place North JeffCo, located at 7307 West 56th Place, consists of 1 parcel of land, containing approximately 0.57 acres. The site contains a building, which is currently used as an indoor firing range. Lead contamination in the indoor firing range is a REC at the site. A Phase II ESA performed by WALSH in 1992 concluded that the contents of bullet catch boxes within the indoor firing range contained lead contamination above commercial standards (17,000 to 330,000 parts per million [ppm]). Liquid waste created during firing range cleanup and possible ventilation system contamination are also concerns associated with the indoor firing range. No access to the interior was available during the Phase II ESA. Based on documents obtained from Colorado Department of Labor and Employment, Oil and Public Safety (OPS), benzene, toluene, ethylbenzene and xylenes (BTEX) compounds and/or volatile petroleum hydrocarbons at the property may have exceeded risk based screening levels (RBSLs) in both soil and groundwater. This is considered a REC. The petroleum-derived contamination is probably associated with USTs that were removed from the site prior to 1992 (WALSH 1995). The status of this UST is closed according to the OPS. The most recent groundwater data available (1994) indicate that BTEX in groundwater may exceed RBSLs at the perimeter of the site. In addition, soil with total volatile petroleum hydrocarbons (TVPH) levels exceeding cleanup levels may remain below the former metal storage building north of the excavation footprint. BTEX and TVPH, which may be encountered in both soil and groundwater during construction, represent a REC at the site which was investigated. Seven soil piles (of unknown origin) were found near the northern perimeter of the property, as well as one pile of asphalt chunks and one pile of gravel. Although they are



not considered to be RECs, these materials are a potential environmental concern because of their unknown origin. Additionally, two metal buildings, no longer present at the site, were reportedly used to store equipment including lawn mowers. Potential exposure pathways are expected to be through contact, inhalation, or ingestion of contaminated soils, primarily during construction or similar activities.

5 PROJECT DESCRIPTION

This Phase II ESA included soil and groundwater sampling at a number of locations on the subject properties included within the proposed OTS. Access was not be granted by the property owners for the Phase II ESA sampling activities on the AURA or Sullivan properties. The sample locations were selected to evaluate the nature and extent of possible soil and/or groundwater contamination from past activities at the site. The sampling and analysis activities were chosen to address those environmental concerns identified in the Phase I ESAs (WALSH 2009), which were considered the highest priorities with respect to anticipated construction of the OTS. The approach to Phase II investigation activities employs U. S. Environmental Protection Agency’s (USEPA’s) Triad Approach (systematic planning, a dynamic work strategy, and the use of real-time and field measurement techniques). This SAP/QAPP has been developed to address the RECs reported in the Phase I ESA prepared by WALSH for the property within the OTS footprint. In general, soil and groundwater sampling locations were selected based on the locations of known current and historic activities, and to determine general distribution of soil and groundwater contaminants at the site, and the estimated direction of groundwater flow.

6 SAMPLING DESIGN

The conceptual site model of the area is based on the assumption that past activities may have contaminated surface and subsurface soils, and shallow (alluvial) groundwater on the property that make up the OTS site. Contamination of soil and groundwater may extend into bedrock, which lies beneath the shallow groundwater table at the site. Sample locations were chosen based on information obtained during the preparation of the Phase I ESAs for the site (WALSH 2009) about previous activities, documented on-site or off-site contamination, groundwater flow direction, and other indications of RECs associated with the subject properties. Groundwater sample locations were selected to provide information about potential groundwater contamination at both the upgradient and downgradient sides of the properties.



The significant potential exposure pathways include dermal contact and ingestion of soils, especially during construction activities, possible contact with groundwater during construction, and possible vapor intrusion of volatile compounds in groundwater or soils at occupied structures. There is no consumption of groundwater at the site. Based on USGS groundwater maps, groundwater in the vicinity of the site is expected to flow toward the southeast at a depth of 2 to 10 feet bgs (Robson 1996). Potential contaminants of concern (PCOCs) in both soils and groundwater include volatile organic compounds (VOCs), semi-volatile organic compounds (SVOCs), and Target Analyte List (TAL) metals. Asbestos and lead are also PCOCs in soil and building materials. This SAP/QAPP proposes a dynamic work plan, and if new evidence is identified during the Phase II ESA that indicates the presence of other contaminants (e.g., chlorinated pesticides or polychlorinated biphenyles [PCBs]) additional laboratory analyses may be obtained, with the prior approval of RTD. In addition, the dynamic work plan permits the use of real-time field measurement techniques to recommend collection of additional samples, if the possible presence of PCOCs is indicated. When conducting Phase II activities including soil borings, upon encountering any visible construction debris that is not concrete, wood, metal, or glass (non-suspect materials), a soil asbestos inspector was present to identify and sample any suspect material to determine if asbestos-containing material (ACM) is present. Soil borings or excavations can provide some additional level of information regarding the potential to encounter ACS, but since the presence of visible asbestos in soil is not typically homogeneous, the likelihood that an ACS conditions will be identified during soil borings or other excavations is low. No suspect ACM was observed in surface or subsurface soils during the investigation and consequently no samples were collected for analysis.

6.1 Potential Exposure Pathways The primary pathways for potential exposure to future construction workers, RTD employees, or visitors in the WRS are expected to be through dermal contact, inhalation, or ingestion of contaminated soils, primarily during construction or similar activities. There is potential exposure of construction workers to both surface and subsurface soils, as well as groundwater at the OTS site. Another possible exposure pathway exists through the inhalation of indoor air impacted by vapor intrusion of VOCs from soil vapor, perhaps originating from VOCs in groundwater. There is no known use of groundwater at the site, and the only surface water is stormwater runoff in drainage areas during storm events.

6.2 Triad Approach The Phase II sampling followed the EPA’s Triad approach to conducting investigations. These include a systematic sampling plan (SAP/QAPP, WALSH, August 2009), a dynamic work plan which can be adapted according to data collected at the WRS site, and the use of real-time (field) measurement techniques.



The systematic plan includes the conceptual site model (CSM), which was derived from information compiled during the Phase I ESAs, and revised using information obtained during the preparation and completion of Phase II work. Sampling activities included real-time (field) measurements of surface and subsurface soil samples, and groundwater. The surface and subsurface soil sample locations are shown in Figure 3. These sample locations were selected to provide both aerial coverage of certain properties and areas of concern, and data at specific locations selected based on observations in the field.

6.3 Sequence of Sampling and Analysis and Dynamic Work Plan Elements

The soil and groundwater sampling followed a sequence developed to optimize the characterization of the WRS site. The actual order of sampling, analysis, and data evaluation was as follows:

Utility locations; Initial inspection collection and analysis of surface soil samples; and Selection and completion of subsurface soil sampling locations (with PID

measurements on soil intervals) and groundwater sample locations.

6.4 Laboratory Analysis Methods Tables (located in Appendix 1) show the reporting limits of the analytical methods specified in this Phase II for potential soil and groundwater contaminants at the OTS site. The tables present the reporting limits of the Test America Laboratory. These reporting limits will be used for all specified analyses. The tables in Appendices 3 through 8 also show the Colorado Department of Public Health and Environment (CDPHE), Hazardous Material and Waste Management Division (HMWMD) CSEV for potential contaminants of concern. In addition the tables show EPA Risk-Based Criteria (RBCs) and CGWS. For almost all of the known and probable contaminants, the reporting limits (RLs) of the specified analytical methods are lower than reasonably applicable actions levels in soil. Standards for arsenic and certain organic compounds are lower than RLs for listed methods. However, the RLs are adequate for the purposes of assessing concentrations, and appropriate, applicable cleanup values in soil that consider risk and background factors. In water, Colorado regulations state that… “Whenever the practical quantitation limit, or PQL, for a pollutant is higher (less stringent) than a standard listed in subsection 2 or 3 above, the PQL shall be used in regulating specific activities. These PQL's shall be approved by the Water Quality Control Division unless an alternate PQL has been established by the applicable implementing agency.”

Soil samples were field screened for VOCs using a PID. The results of the field PID measurements were used, during field sampling activities, to guide additional sampling. The PID data were evaluated, and selected soil samples were submitted to the Test America Laboratory. Field screening for ACM by a CABI resulted in no suspect materials consequently no samples were analyzed.

6.4.1 Surface Soil Sampling Laboratory Analysis for Metals Soil samples were collected using direct-push drilling, and hand augurs. Samples were collected from approximately 0 to 6 inch and 6 to 12 inch depth interval.

6.4.2 Analysis of Surface Soil Samples for Volatile Organic Compounds Soil samples collected from each sample location were initially field screened with a PID for the presence of VOCs. Soil samples were initially split for field screening and quantitative analysis for the presence of VOCs. Samples designated for headspace readings were visually inspected for any evidence of contamination, then transferred into a zip lock bag, sealed, and allowed to volatize for several minutes prior to field screening. Headspace was measured using a field calibrated PID with the results being recorded in the field notes. Surface soil samples (6-12 inches) that yielded readings of greater than 20 ppm using a photoionization detector (PID) were submitted to Test America for analysis for VOCs using EPA Method 8260B, and SVOCs using USEPA Method 8270C.

6.5 Sampling and Analysis of Subsurface Soils Subsurface soil sampling was conducted by utilizing the Hurricane™ truck-mounted rig. Soil boring locations were continuously sampled at 4-foot intervals by direct pushing a 2.25-inch outer diameter acetate-lined dual tube sampling system to the desired depth for sample collection. The recovered sample was described using the universal soil classification system (USCS) to characterize the OTS site geology. Boring terminus was reached after encountering saturated conditions, bedrock or probe refusal. Soil samples were collected from each depth interval for field screening with a PID for the presence of VOCs. Recovered soil samples were initially split for field screening and quantitative analysis for the presence of VOCs. Samples designated for headspace readings were visually inspected for any evidence of contamination, then transferred into a zip lock bag, sealed, and allowed to volatize for several minutes prior to field screening. Headspace was measured using a field calibrated PID with the results being recorded in the field notes. Selection of discrete intervals for analysis was based on possible distribution of contaminants near the groundwater table, near the bedrock surface, and on observations



of the soil cores and the judgment of the geologist. The number and depth of samples selected varied, based on the observations at each location. Soil boring logs are presented in Appendix 2. A portion of the spilt sample designated for laboratory analysis was transferred into laboratory supplied glassware, labeled, placed on ice in an insulated cooler, and transported under chain-of-custody protocol to the Test America Laboratory located in Arvada, Colorado for quantitative analysis. Selected subsurface soil samples were analyzed for metals using EPA Method 6010B + 6020A and 7471A, and SVOCs using EPA Method 8270C. Subsurface soils which yielded PID readings of greater than 20 ppm were analyzed for VOCs using EPA Method 8260B.

6.6 Sampling and Analysis of Groundwater Temporary monitoring wells were installed to determine the condition of the groundwater beneath the proposed OTS property. Groundwater sample locations are shown in Figure 3. Prior to sampling, temporary well locations were gauged for depth to groundwater and total well depth using a Solinst groundwater probe. When possible, approximately one well volume was purged prior to sampling. The initial purge volume was field tested for temperature, conductivity, and pH. All field parameters were recorded in the daily field logs. Groundwater samples collected for analysis were sampled using a peristaltic pump and disposable tubing. The samples submitted for metals analysis were field filtered using a 0.45 micron disposable filter and preserved with laboratory grade nitric acid to pH<2. Collected samples were immediately transferred into laboratory-supplied sample containers, and preserved on ice in laboratory-supplied coolers until shipment to designated laboratories under chain-of-custody protocol to Test America Laboratory located in Arvada, Colorado. Gradient and flow direction were determined from water level measurements from surveyed elevations. The direction of groundwater flow is shown in Figure 4.

Tables 4 through 9 present the contaminant concentrations detected by the laboratory analysis of the soil and groundwater samples.

9 RESULTS AND CONCLUSIONS

Results of the investigation showed that groundwater sample analyses had no detections of organic chemical groundwater contaminants exceeding CGWS. Concentrations of manganese exceeded CGWS secondary standards under Table 2 (taste and odor criteria) in five borings including one (AUR-01) on the Arvada Urban Renewal parcel and four



(NJM-01, NJM-05, NJM-07 and NJM-08) on the North Jeffco Metro parcel. Manganese concentrations ranged from 600-1900 ug/l versus the CGWS Table 2 standard of 50 ug/l. The concentration of iron exceeded CGWS secondary standards under Table 2 (taste and odor criteria) in one boring (NJM-8) at 980 ug/l versus the CGWS Table 2 standard of 300 ug/l. These findings are not considered environmentally significant since both iron and manganese are naturally occurring and there is no current or planned consumptive use of groundwater. Soil sample results showed elevated lead concentrations at five locations. Three samples (NJM-12, NJM-13 and NJM-14) had lead concentrations exceeding the CSEV worker protection standard of 800 mg/kg with lead concentrations ranging from 1200-7600 mg/kg. These samples were collected adjacent to the shooting range near windows or vents and most likely represent airborne lead deposition emitted from the range. Visible lead fragments (spent ammunition) were observed on exterior vent/window ledges on the outside surface of the range building. Two soil samples NJM-2 and NJM-10 had lead concentrations equaling or exceeding the CSEV standard for residential exposure of 400 mg/kg. These samples were also proximate to the shooting range. Arsenic concentrations exceeded the CSEV standard of 1.6 mg/kg for worker protection at ten locations. However, arsenic commonly occurs naturally at concentrations above the CSEV. Arsenic concentrations ranged from 2.4 mg/kg to 30 mg/kg at NJM-4. The maximum arsenic concentration of 30 mg/kg at NJM-4 was the only sample which exceeded the 25 mg/kg standard which CDPHE considers the maximum background arsenic concentration for the urban metropolitan Denver area. Soil sample analyses showed exceedence of residential exposure CSEV for three semi-volatile polycyclic aromatic hydrocarbons (PAHs) (benzo[a]pyrene, benzo[b]fluoranthene and dibenzo [a,h]anthracene). All concentrations were below CSEV worker protection concentrations which would be likely be the applicable standard for the OTS construction since no residential land-use is planned at the OTS site. PAHs are commonly found in soil and groundwater samples from many commercial and industrial properties, which have been asphalt-paved or are subject to runoff from paved areas. Appreciable concentrations of PAHs are present in fuel oils because of the common practice of using both uncracked and cracked residues in their manufacture. In addition to lead contaminated soils, the interior of the shooting range was not investigated and likely contains elevated concentrations of lead and arsenic. Following decommissioning and decontamination of the firing range and surrounding soils,



confirmation sampling of the range, building materials and surrounding soils is recommended prior to RTD taking possession of the property. No suspect ACM was observed and no sample analyses were performed for ACM. However any ACM, solid or hazardous waste encountered during construction should be managed by an approved Materials Management Plan under the overall provisions of a Voluntary Cleanup Plan (VCUP) approved by CDPHE. Limitations The conclusions presented in this report were developed from the review of information developed during the Phase I and Phase II site investigations, field observations, measurements, and laboratory analyses. The conclusions pertain only to the properties investigated because right-of-entry was not obtained from two other properties within the planned station footprint In addition, physical constraints, such as equipment, vehicles, underground utilities, and property boundaries limited soil and groundwater sampling areas. Subsurface conditions may vary at locations and times other than those tested, and practicality prohibits the investigation of all soil and groundwater. If additional information concerning site environmental conditions becomes available, the conclusions presented in this report will not be considered valid unless this information is reviewed and the conclusions of this report are modified and approved in writing by WALSH.

Colorado Department of Public Health and Environment, Hazardous Materials and Waste Management Division, Table 1. Colorado Soils Evaluation Values (CSEV), December 2007. Standards based on "Worker" criteria (Worker values are considered protective for indoor office workers with occasional contact with outdoor soil, and for outdoor workers engaged in light to moderate activity. Values are NOT APPLICABLE to outdoor workers routinely engaged in contact-intensive activity. For facilities where contact intensive use is anticipated, additional analysis and consultation with a toxicologist will be required to determine appropriate site-specific inputs to the risk equations).

Notes: A,1,2,3 M Drinking water MCL A,1,2,3 C Carcinogens classified by the EPA as A, B1 or B2

A,1,2,3 D Measured as dissolved concentration. The sample water shall be filtered through a 0.45 micron membrane filter prior to preservation. The total concentration (not filtered) may be required on a case-by-case basis if deemed necessary to characterize the pollution caused by the activity

A,1,2,3 F These more stringent levels are necessary to protect livestock watering. Levels for parameters without this footnote are set to protect irrigated crops at the same level. Where a party can demonstrate that a livestock watering use of ground water is not reasonably expected, the applicable standard for lead is 5.0 mg/l.

CSEV C Standard based on carcinogenic risk corresponding to a lifetime risk of 1 E-6.

CSEV Nc Standard based on non-carcinogenic risk corresponding to a hazard quotient (HQ) of 1. For facilities where multiple non-carcinogenic chemicals are present, HQ values should be divided by a factor of 10 to account for additivity. If adjusted table values are exceeded, consultation with a toxicologist is recommended to assess likely impact on specific target organs.

CSEV Pending Table values shown as pending are under review. Users should contact the Division if they have an urgent need for a table value for a constituent currently shown as pending.


CSEV 5

Table value is capped at an upper concentration limit of 1,000 mg/kg. The Division believes it is necessary to cap the chronic risk scenario and soil-to groundwater modeling concentration outputs, because the two modeling approaches can result in the calculation of soil concentrations that are very high in an absolute sense, possibly leading to acute health impacts, the presence of free-phase contaminant in soil, or leaving behind constituent levels in soil that might constitute a hazardous waste. Users may contact the Division if they have a need for specific risk-based values, or modeled groundwater concentrations.

CSEV 7 Value based on current EPA-recommended methodology for assessment of chemicals causing cancer through a specific mutagenic mode of action (MOA). CSEV 8 Value based on current CDPHE policy for this chemical. Contact the Division if additional information is needed.

CSEV 9 Table value assumes 3% dermal absorption. Vapor pressure for this volatile organic chemical (VOC) is less than that for benzene, indicating additional potential for dermal absorption. Table values for VOCs with a vapor pressure greater than that of benzene are calculated based on dermal absoption of 0%.

CSEV 10

For many locations in Colorado, naturally occurring concentrations of arsenic in soil are expected to be higher than the risk-based value listed in Table 1. If adequate background sampling is available that confirms the naturally occurring background concentration of arsenic adjacent to a facility is higher than the table value, the background concentration may be used for site screening and remediation purposes.

CSEV 11

Screening levels for lead are based on chemical-specific models, rather than the EPA Region 9 risk algorithm used to derive other table values. The residential value is based on default inputs to EPA’s IEUBK model for lead in children. The worker value is based on EPA’s adult lead model (ALM), using default values recommended in EPA’s 2002 review of CDC’s NHANES III report. Consideration of site-specific inputs to the IEUBK or ALM lead models and consultation with a toxicologist is strongly recommended for facilities with lead levels in soil that exceed the residential or worker table values. Contact the Division for additional information about details of the lead models and site-specific considerations.
