Re: Site Assessment Western Avenue Yard 2741 West Grand Ave Chicago, Illinois

Dear Mr. Cabonor:

GaiaTech Incorporated dba as RPS GaiaTech has completed a Site Assessment at the Western Avenue facility located at 2741 West Grand Avenue, Chicago, Illinois (the “Site”). The scope of work was completed in accordance with the approved proposal, dated April 14, 2016.

BACKGROUND

Metra operates a rail yard at 2741 West Grand Avenue in Chicago, IL which includes a fuel and petroleum product storage and dispensing area. Metra is planning to replace approximately 850 linear feet of below grade piping with new above ground lines. Approximately 750 linear feet of the piping runs underneath or near the tracks in the active rail yard, therefore the below grade piping will be abandoned in place.

Removal and closure of UST system components (including piping) is regulated under 35IAC Part 175 (Technical Requirements for USTs) and Part 176 (Administrative Requirements for USTs). Part 175.840 outlines the requirements which must be met in order to abandon UST components in place. These requirements include a demonstration of eligibility for a waiver of the removal requirement for the UST and/or piping, which is typically only granted where it would be infeasible to remove the system due to loss of adjacent or subjacent support of nearby structures, such as railroad tracks, streets, and other USTs. This determination may be made by a professional engineer, and is subject to OSFM review for approval. Part 175.840 also requires preparation of a Certificate of Site Conditions with site drawings prior to abandoning the UST and/or piping.

Part 176.330 outlines the requirements for completing a Site Assessment prior to abandoning a UST ‐ the same requirements apply to a UST system or portions of a UST system, including underground piping. The procedures for selecting sample locations for a Site Assessment under Part 176.330 are referenced and described in Part 734.210 (Pollution Control Board, Early Action for USTs). These

Addendum 2Site Assessment

Mr. Todd Cabonor October 6, 2016 Page 2

requirements include two soil borings/samples (one on each side of the piping) for every 20 linear feet (or fraction thereof) of piping. Part 734.210 directs the agency to excuse the drilling of one or more borings if drilling is made impractical by site‐specific circumstances. RPS GaiaTech understands that active railroad tracks are recognized by the agency as making soil borings in those locations impractical. SCOPE OF WORK The subject site assessment consisted of 10 soil borings, one installed along each side of the piping run, spaced every 20 feet. Per Part 734.210, these borings were conducted to a maximum depth of 15 feet and at least 1 soil sample was collected from each 5 foot section of each boring, at a depth where contamination is most likely to be present. Samples were analyzed for volatile organic compounds (VOCs) and polynuclear aromatic hydrocarbons (PAHs). Prior to field work, utilities were cleared through the Illinois and City of Chicago one call utility locating services. Ground Penetrating Radar Systems, Inc. (GPRS), under the direction of RPS GaiaTech, performed a geophysical survey of the proposed sampling locations for evidence of unidentified buried utilities or underground structures. On May 7, 2016 and June 8, 2016 RPS GaiaTech mobilized to the site with a direct push (Geoprobe®) contractor to conduct the soil borings. Due to the possibility of buried utilities in the vicinity of the sample locations, an “air knife” was to be used to prevent damage. An air knife consists of an air compressor which provides the air movement for a vacuum unit. This vacuum, combined with the compressed air, allows for the safe excavation of soil and gravel without damaging the buried utilities. The air knife was used to excavate a 5‐inch diameter borehole to a depth of 5 feet below ground surface (bgs) at each boring. The Geoprobe® was then used to conduct the remainder of the boring. A total of eleven borings were conducted. Soil boring locations are illustrated on the Boring Location Map (Figure 1). Individual sample locations were selected to be as close as possible to the underground piping trench while providing adequate clearance for the underground utilities and the rail tracks. The soil borings were completed using direct push and air knife technology, as described above. The borings were advanced to a maximum depth of 15 feet bgs. The down‐hole non‐dedicated sampling equipment was decontaminated between locations using an Alconox®/water wash and scrubbing, followed by a potable water rinse. New and disposable sampling materials were used when possible (e.g., plastic sample liners and gloves). During use of the Geoprobe®, continuous soil samples were collected using steel sampling tubes with plastic sample liners. The soil samples collected from each bore hole were visually described and classified using the Unified Soil Classification System as a guide. Observations were also made for the presence of fill material and visual/olfactory evidence to suggest impact (e.g., unusual odors, staining, etc.) Representative samples of the soil intervals were placed in sealed plastic bags for headspace analysis with a photoionization detector (PID). The PID readings are expressed in units of parts per million (ppm) by volume, relative to an isobutylene standard. The field screening was used to provide an indication of


the potential presence of volatile organic constituents and to aid in the selection of samples for laboratory analysis. The soil sample descriptions and the field screening results were recorded on boring logs (see Appendix A). Based on field screening results and visual observations, one soil sample was selected from each 5‐foot sample liner for laboratory analysis. Soil samples for analysis were placed in laboratory supplied jars and stored in a cooler with ice. Appropriate decontamination procedures were followed during sample collection and proper chain of custody procedures were employed. At the completion of sampling, the Geoprobe section of each boring location was backfilled with bentonite chips and excess cuttings. The railroad ballast material (coarse gravel) encountered in the upper portion of each boring (see geology section below) removed by the air knife was returned to the upper portion of the borehole. The surface was then patched (if necessary) to match the pre‐existing conditions (concrete). Analytical Testing Program The soil samples were submitted to Stat Analysis following standard chain‐of‐custody procedures. The soil samples were analyzed in accordance with United States Environmental Protection Agency (USEPA) SW‐846 Methods for VOCs using USEPA Method 8260B and PAHs using USEPA Method 8270C, as required under Part 734.210. FINDINGS Geology and Hydrogeology The subsurface conditions at the Site generally consist of gravel backfill (primarily railroad ballast material) to a depth of approximately 7 feet bgs underlain by silty clays. At some locations perched water was present in the backfill at 5.5 feet bgs. Soil boring logs are presented in Appendix A. Field Screening Results Elevated PID readings were recorded from soil samples collected from borings WA‐8 and WA‐10. Analytical Results RPS GaiaTech compared the analytical results to the screening levels established in IEPA’s TACO. The soil analytical results are summarized in Table 1. The analytical reports and chain‐of‐custody records are included in Appendix B. Select PAH compounds were detected in soil samples in excess of the default background concentrations developed by IEPA for the City of Chicago. However, the detected compounds did not exceed the default TACO standards. CONCLUSIONS RPS GaiaTech has completed the investigation at the Western Avenue Yard facility located at 2741 West Grand Avenue, Chicago, Illinois. The following conclusions are based on the observations and analytical results obtained during this investigation:


Concentrations of PAH compounds were detected in soil samples above the default City of Chicago background levels, but below the TACO Soil Remediation Objectives.

The results of this investigation may be used in the application of a permit from the Chicago Department of Public Health for the removal and/or abandonment of the underground pipe lines at the site.
