Section 1

Introduction and Background This Voluntary Cleanup and Redevelopment Program (VCUP) Addendum has been prepared by Brown and Caldwell (BC) on behalf of the City and County of Denver (CCoD) to address additional remedial activities to remove concrete crusher material used as backfill in the former Highline Canal. This material was used as backfill during the implementation of the VCUP Application for the original Highline Canal Phase II area shown on Figure 1. The objective of this VCUP Addendum is to remove the concrete crusher material used as backfill during the implementation of the VCUP discussed herein; thereby, removing the remaining material that contains compounds exceeding Stapleton Numeric Criteria (SNC) and maintaining the No Action Determination (NAD) previously issued by the Colorado Department of Public Health and Environment (CDPHE) for the High Canal Phase II Addendum area (Site).

The Site is in the City of Aurora, Colorado, and is approximately 24 acres. Figure 1 shows the general location of the original Highline Canal Phase II area within the former Stapleton International Airport (SIA). This area is a rectangular parcel bounded by East 25th Avenue on the south, Peoria Street on the east, Moline Street on the west, and vacant land known as Parcel A on the north. The Site is a portion of the original Highline Canal Phase II area and is shown within the hatching in Figure 1. The remaining portion of the original Highline Canal Phase II VCUP identified in Figure 1 (shown with a stippling pattern) will be addressed separately as a VCUP Supplement to the original VCUP Application.

The Remedial Action Plan described in the CDPHE-approved VCUP Application for the original Highline Canal Phase II area included the removal of asbestos-containing material (ACM) and SNC-impacted soil/debris (BC 2015). Material and debris exceeding SNC were removed to native material throughout the former canal outlined in Figure 1. Concrete crusher material was placed from excavation bottom to approximately 8 feet below the original ground surface (bgs) following excavation and confirmation sampling activities at the former canal. Approximately 40,000 loose cubic yards were used in the backfilling of the former canal. Additional details regarding the Remedial Action Plan summary and field activities are provided in the Closure Report Summary and No Action Determination Request report (Closure Report [BC 2016]).

Prior to the above discussed excavation activities, an initial surface inspection was performed within the original VCUP boundary. Six debris areas containing surface ACM were identified and subsequently removed for off-site disposal in accordance with the Soil Characterization and Management Plan in Appendix B of the VCUP Application [BC 2015]). In addition, prior to the conclusion of backfilling activities of the former canal area, approximately 4 to 6 inches of the surface soil where remedial activities or vehicle traffic occurred within the original VCUP area (e.g., soil under overburden stockpile areas, haul roads, and scale locations) was scraped and used for backfill in the former canal area. This scraped area is shown on Figure 2. The scraped surface soil was screened for ACM using the minimal screening approach described in the Closure Report (BC 2016).

Section 2

NAD and Subsequent Data Based on the Closure Report (BC 2016), a NAD was approved by CDPHE on August 5, 2016. However, subsequent to CDPHE’s approval of the NAD, Recycled Materials Company, the operator of the crusher unit, provided additional analytical data of the concrete crusher product used as backfill in the former canal. The analytical data for the concrete crusher product are included as Appendix A. The additional analytical data supplied by Recycled Materials Company indicated the concrete crusher product contained four substances at concentrations exceeding SNC. The substances exceeding SNC were benzo[a]pyrene, benzo[b]fluoranthene, indeno[1,2,3-cd]pyrene, and total polychlorinated biphenyls (PCBs). The concentrations detected for each of these substances were below the corresponding United States Environmental Protection Agency (EPA) Regional Screening Levels (RSLs) for a residential scenario (see Table 1). Nevertheless, since the concentrations exceeded SNC, additional sampling of the backfill was performed in accordance with the CDPHE-approved Concrete Crusher Material Sampling and Analysis Plan (Appendix B).

On April 20 and 21, 2017, BC collected and analyzed soil samples from eight soil boring locations (shown on Figure 3). In addition, one sample from the remaining stockpile of concrete crusher material was collected and analyzed in accordance with the Concrete Crusher Material Sampling and Analysis Plan. Based on the Recycled Materials Company data, and in accordance with the Concrete Crusher Material Sampling and Analysis Plan, the samples were analyzed for semi-volatile organic compounds (SVOCs) using EPA Method 8270C, PCBs using EPA Method 8082, Resource Conservation and Recovery Act total metals using EPA Method 6010B, and total mercury using EPA Method 7471A.

The analytical results for the samples of concrete crusher material obtained from the above discussed soil borings and stockpile confirmed that the concrete crusher material exceeded SNC for three analytes: benzo(a)pyrene, benzo(b)fluoranthene, and dibenz(a,h)anthracene (Appendix C). Figure 3 shows the results for these analytes in comparison to SNC and EPA RSLs for residential use.

Since the concrete crusher material contains benzo[a]pyrene, benzo[b]fluoranthene, and dibenz[a,h]anthracene at concentrations that exceed SNC, additional remedial action was required to support the NAD approval. Therefore, this VCUP Addendum was prepared to address the additional remedial activities to remove the concrete crusher material previously used as backfill in the former Highline Canal.

Section 3

Remedial Action Plan Summary To maintain the NAD for residential use at the Site, concrete crusher material will be removed and replaced with soil backfill material that does not exceed SNC. Remedial activities will include: • Concrete crusher material excavation and disposal at an approved disposal facility (e.g., Denver

Arapahoe Disposal Site [DADS]); • Subsequent confirmation sampling; and • Backfilling with approved soils as specified in the VCUP Application (BC 2015).

Excavation will be completed to the prior base of excavation (i.e., bottom of concrete crusher material). Figures 4 and 5 show the base elevation of the Highline Canal excavation floor, the elevation of the top of the crusher material, and the ground surface elevation that was surveyed by Flatirons Surveying, Inc. during the implementation of the original VCUP Application between November 13, 2015 and February 24, 2016. For reference, the boring locations (BH-01 through BH-08) are located on this figure. Figure 5 shows the approximate thickness of the concrete crusher material, the thickness of the overlying soil (placed over the concrete crusher material) that met SNC per the VCUP Application, and the relative ground surface elevation through four transects through the former canal area.

Confirmation sampling will be conducted to verify removal of concrete crusher material exceeding SNC. The sampling procedures will generally follow the VCUP Application (BC 2015), as shown in Figure 6, with minor modifications discussed herein. Upon receipt of confirmation samples demonstrating results are below SNC, the excavation will be backfilled with soil in accordance with the VCUP Application.

Remedial activities will also be performed in general accordance with the CDPHE-approved VCUP Application (BC 2015). Since ACM was removed previously, no air monitoring will be conducted during remedial activities and no moisture content testing will be performed on the concrete crusher material during the implementation of the remedial activities. A summary of the remedial activities proposed in the VCUP Addendum is provided below.

3.1 Site Preparation The following activities will be completed as part of the mobilization activities. • Install Site perimeter fencing. • Review storm water management plan and soil controls. • Stage construction and supply trailers on Site. • Coordinate support facilities on Site to make facilities operational. • Obtain fire hydrant permits and install water meter regulators, if necessary. • Mobilize heavy equipment to the Site. • Demarcate the entrance and exit to the Site. • Complete road and initial survey work.

• Scrape soil backfill overlying the concrete crusher material previously screened (during the implementation of the original VCUP Application) soils (approximately 0 to 7 feet bgs) from the excavation area that meets the VCUP Application’s testing protocol; therefore, leaving up to approximately 1 foot of the previously screened soil overlying the concrete crusher material.

• Stockpile the scraped soil backfill for future use as backfill after the concrete crusher material has been removed.

3.2 Concrete Crusher Material Remediation via Excavation To remove impacts exceeding SNC, the concrete crusher material will be excavated throughout the Site. The following summarizes the activities planned for the removal of the concrete crusher material.

3.2.1 Air Monitoring Air monitoring activities are not needed as ACM was removed previously and should not be encountered during excavation of concrete crusher material (i.e., it was already removed during the implementation of the original VCUP Application and no ACM was observed in the backfill soil or the concrete crusher material). If for some unforeseen reason air monitoring is deemed necessary, monitoring will be coordinated with CDPHE and would likely be conducted per the VCUP Application (BC 2015) and Closure Report (BC 2016). However, for the purposes of this VCUP Addendum, it is not anticipated that air monitoring will be necessary or required.

3.2.2 Concrete Crusher Material Transportation Plan Because ACM was removed from the former canal area and no ACM is anticipated to be encountered during the implementation of this VCUP Addendum, the concrete crusher material is planned to be loaded directly into trucks, covered in accordance with standard Department of Transportation requirements, and transported to DADS. No Alternative Waste Transportation Plan, soil moisture content monitoring during transport, or truck liner procedures (as implemented in the original VCUP Application) are needed nor applicable for this material.

3.3 Concrete Crusher Material Confirmation Sampling Confirmation sampling and analysis will be conducted after the concrete crusher material is removed. This may be performed in stages as the excavation proceeds to different areas of the former canal footprint. The proposed floor and sidewall SNC confirmation sampling procedures are described below and shown in Figure 6.

3.3.1 Excavation Floor Confirmation Sampling Confirmation samples will be collected from the bottom of the excavations after the concrete crusher material has been excavated to the floor of the original excavation (i.e., to native soil). Confirmation sampling will be conducted in accordance with the CDPHE-approved plan discussed below.

One composite sample will be collected for every ten grid columns (west of the column 28/29 boundary) or one per ten grid cells (squares east of column 28/29 boundary) as proposed in Figure 6. The composite sample will consist of four aliquots that will be composited into a single sample. The sampling procedure is intended to provide a floor composite sample in targeted grid columns/cells that will verify the underlying material is below SNC.

Floor composite sample aliquots will be collected from the soil/material most likely to be impacted based on field observations (e.g., color or texture similar to concrete crusher material). If no field observations were made that indicated potential impacts on the excavation floor, the four aliquots will be

VCUP Addendum │ Highline Canal Phase II Closure Report Section 3

3-3

Use of contents on this sheet is subject to the limitations specified at the end of this document. VCUP Addendum_Actual and Final_07102017.docx

evenly spaced in the grid column/cell. The four composite sample aliquots will be placed in a sealable, plastic bag and homogenized before the sample is placed in the sample container for subsequent analyses. Based on the understanding of the concrete crusher material and the prior confirmation sampling documented in the Closure Report, the samples will be analyzed for SVOCs using EPA Method 8270D.

3.3.2 Excavation Sidewall Confirmation Sampling Confirmation samples will be collected from the sidewalls of the excavations after the removal of concrete crusher material to the floor of the original excavation (i.e., to native soil). Confirmation sampling will be conducted in accordance with the CDPHE-approved plan discussed below.

Sidewall samples will be collected after the concrete crusher material is removed from the sampled grid column/cell. Therefore, material will be removed laterally until native material is encountered or a grid column/cell boundary is reached. At a minimum, one sidewall sample will be collected for approximately every 250 linear feet of sidewall. In locations where the sidewalls are deeper than 10 feet bgs, shallow (between 7 and 10 feet bgs) and deep (greater than 10 feet bgs) sidewall grab samples are proposed. Sidewall confirmation samples will be collected from the soil/material most likely to be impacted (e.g., color or texture similar to concrete crusher material).

Vertical sidewalls will likely be present throughout the former canal excavation after the concrete crusher material removal. For safety reasons, confirmation samples will be retrieved with an excavator bucket where necessary. When an excavator bucket is used for sample collection, the portion of the excavator bucket that was used for the sample collection will be decontaminated prior to the retrieval of sidewall grab samples. Sample collection will occur above the decontaminated portion of the bucket. Sidewalls that are safe to sample manually will be collected from the soil/material most likely to be impacted based on field observations (e.g., color or texture similar to concrete crusher material). Based on the understanding of the concrete crusher material and the prior confirmation sampling documented in the Closure Report, the samples will be analyzed for SVOCs using EPA Method 8270D.

3.4 Backfill The analytical data for the confirmation samples will be compared to SNC. If the analytical data do not indicate any exceedances of SNC, the excavation area will be backfilled. As discussed in Section 3.1, the backfill soil overlying the concrete crusher material will be screened and set aside during the remediation and be used to backfill the excavations. Additional material brought on Site for backfill will be screened per the Import Soils Protocol (Appendix H of the VCUP Application). Soil from on Site used for backfill will be from borrowed sources previously approved by CDPHE.

3.4.1 Final Site Scrape A final scrape will not be necessary as asbestos is highly unlikely to be encountered; however, if deemed necessary, the final scrape will follow the VCUP Application.

3.5 Post-Excavation Survey A post-excavation survey will be completed to establish final depths, limits and grades for the excavation area including a topographic map of the final excavation floor.

Project: Waste Characterization

Report Number: 280-77238-1

With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples,

the reporting limits are adjusted relative to the dilution required.

Calculations are performed before rounding to avoid round-off errors in calculated results.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the

individual sections below.

RECEIPTThe sample was received on 11/24/2015 at 4:00 PM; the sample arrived in good condition, properly preserved and, where required, on ice. The temperature of the cooler at receipt was 0.5º C.

Job ID: 280-77238-1 (Continued)

Laboratory: TestAmerica Denver (Continued)

DCB Decachlorobiphenyl and Tetrachloro-m-xylene failed the surrogate recovery criteria low for STAPLETON CONCRETE FINESMS (280-77238-1MS).

Sample STAPLETON CONCRETE FINES (280-77238-1)[10X] required dilution prior to analysis due to the nature of the sample matrix. The reporting limits have been adjusted accordingly.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

POLYCHLORINATED BIPHENYLS (PCBS)Sample STAPLETON CONCRETE FINES (280-77238-1) was analyzed for polychlorinated biphenyls (PCBs) in accordance with EPA

SW-846 Method 8082. The samples were prepared on 11/25/2015 and analyzed on 12/02/2015.

The following sample appears to contain a mixture of Aroclor-1254 & Aroclor-1260: STAPLETON CONCRETE FINES (280-77238-1). The

sample has been quantified and reported as Aroclor-1254, as it appears to be the most prevalent of the Aroclors. Due to these Aroclors having shared peaks, there is increased qualitative and quantitative uncertainty associated with this result.

The following samples underwent a sulfuric acid clean-up, via EPA Method 3665A, to reduce matrix interferences: STAPLETON CONCRETE FINES (280-77238-1), (LCS 280-305612/3-A), (MB 280-305612/1-A).

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

TOTAL METALSSample STAPLETON CONCRETE FINES (280-77238-1) was analyzed for total metals in accordance with EPA SW-846 Method 6010B. The samples were prepared on 12/02/2015 and analyzed on 12/09/2015.

Barium was detected in method blank MB 280-306084/1-A at a level that was above the method detection limit but below the reporting

limit. The value should be considered an estimate, and has been flagged. If the associated sample reported a result above the MDL and/or RL, the result has been flagged. Refer to the QC report for details.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

TOTAL MERCURYSample STAPLETON CONCRETE FINES (280-77238-1) was analyzed for total mercury in accordance with EPA SW-846 Method 7471A. The samples were prepared and analyzed on 11/25/2015.

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

PERCENT SOLIDS

Sample STAPLETON CONCRETE FINES (280-77238-1) was analyzed for percent solids in accordance with ASTM D2216-90. The samples were analyzed on 11/27/2015.

Subject: Crusher Fines Sampling and Analysis

Highline Canal Phase II Site (RV160614-1-1)

Former Stapleton International Airport Denver, Colorado

Dear Mr. Apostolopoulos:

Brown and Caldwell (BC) has prepared this letter on behalf of the City and County of

Denver (CCoD). The purpose of this letter is to provide results of the concrete crusher

fines used at the Highline Canal Phase II Site located at the former Stapleton Interna-

tional Airport (Site). These results were discussed on a call with you Friday May 5, 2017.

This letter has been prepared to document those discussions and the requirements of

the Colorado Department of Public Health and Environment (CDPHE) in order to main-

tain the No Action Determination (NAD) for the Site. The following provides a back-

ground, sample results, and required actions to maintain the Site’s NAD.

Background

As described during our discussion on April 14, 2017, concrete crusher fines material

was placed into the excavation from the bottom of the excavation to approximately eight

feet below original ground surface (bgs) following the excavation and confirmation sam-

pling activities at the Site. Approximately 40,000 loose cubic yards were used in the

backfilling of the Site.

Based on CCoD’s knowledge of the concrete crusher operations, only concrete was used

to make the concrete crusher fine material that was used to backfill the Site excavation

area and not asphaltic concrete. However, a separate crushed asphaltic concrete pile,

that was not used in the backfilling of the Site, was located adjacent to the piles of con-

crete crusher fines.

Prior to using the concrete crusher fines at the Site, a sample was collected and ana-

lyzed from the crusher pile. Attached is the analytical test results of the concrete

crusher fines product from Recycled Materials Company (the operators of the crusher

unit). This sample was provided to CCoD as the sample identified as Stapleton Concrete

Fines collected on November 24, 2015 and analyzed for the following analytes:

Volatile organic compounds (VOCs) using EPA Method 8260B,

Semi-volatile organic compounds (SVOCs) using EPA Method 8270C,

Gasoline range organics (GRO) using Method 8015B_GRO,

While benzo[a]pyrene (BaP), benzo[b]fluoranthene, indeno[1,2,3-cd]pyrene, and total

polychlorinated biphenyls slightly exceed SNC criteria, they are below the corresponding

EPA RSLs for a residential scenario (values shown in the above table from the EPA RSL

for residential use using the calculator value).

On April 11, 2017, CCoD received a letter (attached) from Katy Dunn of Forest City Sta-

pleton, the potential purchaser of the Site. In this letter Ms. Dunn indicated that the

CDPHE would need further analysis of the concrete crusher fines.

On April 17, 2017, BC submitted to the CDPHE a sampling and analysis plan to assess

the crusher fines relative to the Stapleton Numeric Criteria (SNC) and the Environmental

Protection Agency (EPA) Regional Screening Levels (RSLs) for residential (website calcu-

lator value: https://epa-prgs.ornl.gov/cgi-bin/chemicals/csl_search). This sampling and

analysis plan was approved by the CDPHE on April 19, 2017. The following discusses

the sampling activities of the concrete crusher fines.

Sampling Activities of the Concrete Crusher Fines On behalf of CCoD, BC collected and analyzed samples of the concrete crusher fines

from the excavation using a drill rig with hollow-stem augers and continuous coring

tools. The samples were collected on April 20 and 21, 2017 as follows:

Remaining Crusher Fines Pile - One composite sample was collected on April 20,

2017 from the remaining Site concrete crusher fines backfill stockpile. Five

grab samples were initially collected from different points in the backfill stock-

pile and placed into one decontaminated container, mixed, and then placed into

sample containers (for one total composite sample [Pile-01]) from the remaining

Site concrete crusher fines backfill stockpile. This sample was placed on ice and

submitted to the offsite laboratory for analysis under chain-of-custody protocol.

Backfilled Material – Concrete crusher fine samples were collected on April 20

and 21, 2017 from the backfilled material located approximately between ap-

proximately 8 and 20 feet bgs. The samples were collected from continuous

core barrels retrieved during hollow-stem auger drilling at the eight locations

(BH-01 through BH-08) shown on the attached Figures 1, 2, and 3. At each loca-

tion, three grab samples were placed into one decontaminated container, ho-

mogenized. Splits of each grab sample were collected into a separate decontam-

inated container, homogenized and then placed into sample containers for one

total composite sample from each of the eight locations. These samples were

placed on ice and submitted to the offsite laboratory for analysis under chain-of-

custody protocol.

Based on the prior sample (Stapleton Concrete Fines - attached), the above samples

were analyzed for SVOCs using EPA Method 8270C, PCBs using EPA Method 8082, and

total Resource Conservation and Recovery Act (RCRA) total metals using EPA Method

6010B and 7471A for total mercury.

In addition to the composite samples collected from approximately 8 to 20 feet bgs at

each of the 8 sample locations, depth specific samples were retained from three depths

(shallow - approximately 8 to 10 feet bgs, medium – approximately 13 to 15 feet bgs,

and deep – approximately 16 to 18 feet bgs) and held at the laboratory pending the re-

sults of the above composite samples. However, based on the results of the SVOCs dis-

cussed below, these depth specific samples were not analyzed since each composite

sampled exceeded the SNC and EPA RSL (residential) for BaP, except the sample from

BH-05. The depth discrete samples were submitted to the laboratory and put on hold

pending the results of the composite samples.

Sampling Results of the Concrete Crusher Fines

Figure 1 shows the results for the analytes that were tested and exceeded SNC and/or

the EPA RSL calculator value for residential (BaP, benzo[b]fluoranthene, and

dibenz[a,h]anthracene). The SNC value for BaP was exceeded in each of the samples,

except BH-05. The EPA RSL calculator value for residential use was exceeded for BaP in

five of the eight boring locations (BH-01, BH-03, and BH-06 through BH-08). The

benzo[b]fluoranthene, and dibenz[a,h]anthracene results for BH-07 exceed SNC values.

The rest of the results were below SNC and EPA RSL calculator values for residential

use.

Actions That Are Required by CDPHE to Maintain the NAD Determination

Figures 2 and 3 show the base elevation of the Highline Canal excavation floor, the ele-

vation of the top of the crusher fine material, and the ground surface elevation at the

completion of the backfilling operations. For reference, the boring locations (BH-01

through BH-08) are located on this figure. Figure 3 shows the thickness of the crusher

fines, the overlying soil and the relative ground surface elevation through four transects

going generally north to south through the former Highline Canal area. The locations of

these transects are shown on Figure 3.

As we discussed with Greg Holt of the CCoD on May 5, 2017, for the CDPHE to keep the

NAD determination for residential use at the Site one of two options would be required:

1. Removal and proper disposal of the crusher fine material at an approved dis-

posal facility (e.g., Denver Arapahoe Disposal Site) or reuse at a site that has the

appropriate land use (i.e., industrial or open space) with backfilling of the exca-

vation with soil material that meets the criteria specified in the VCUP Application.

2. Deed restriction of the property to not allow excavations within the Site prior to

receiving approval, especially excavations below approximately eight feet below

final developed ground surface where crusher fines materials could be encoun-

tered. In addition, preparation and continuous implementation of a materials

management plan to address any excavation activities in the property including

the management and disposal of crusher fines material offsite to an approved

disposal site when/if crusher fines material is encountered.

I trust the above provides the necessary information regarding the additional sampling

and analysis of the concrete crusher fines for the CDPHE, as discussed in our April 17,

2017 sampling and analysis plan. In addition, I believe that I have embodied the ac-

tions required by the CDPHE to maintain the NAD for unrestricted residential use as dis-

cussed in the VCUP Application. Please verify the above and if you have any questions,

please do not hesitate to call me at (303) 239-5492.

Sincerely,

Brown and Caldwell

ONE LAB. NATIONWIDE.CASE NARRATIVE

All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of thedata.

ONE LAB. NATIONWIDE.CASE NARRATIVE

All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of thedata.
