EMP Version 2, January 2021     PART 1. Soil  1) Known or suspected contaminants in soil (list general groups of contaminants):  Assessment activities completed at the Brownfields property included the collection of five (5)  shallow composite soil samples in areas planned for disturbance during future grading activities  and twelve (12) soil samples in areas of potential environmental concern.  A tabular summary of  soil sample analytical data in comparison to the DEQ Preliminary Soil Remediation Goals (PSRGs)  is included as Table 1 and Table 2.  Soil sample locations are shown in Figure 3, and compound  concentrations above the PSRGs are shown in Figure 4.  A summary of the soil sampling results is  provided below:    Volatile Organic Compounds  Laboratory analytical results indicate that low levels of several VOCs were detected in soil  samples collected at the Site at concentrations above laboratory method detection limits, but  below the DEQ PSRGs.    Semi‐Volatile Organic Compounds  Laboratory analytical results indicate that low levels of several semi‐volatile organic compounds  (SVOCs) were detected in soil samples collected at the Site at concentrations above laboratory  method detection limits, but below the DEQ PSRGs.    Metals  Laboratory analytical results indicate that several metals were detected at concentrations above  the laboratory method detection limits.  The metal arsenic (24 milligrams per kilogram [mg/kg])  was detected in composite sample COMP‐1 at a concentration above the DEQ Residential PSRG  and DEQ Industrial/Commercial PSRG of 0.68 mg/kg and 3.0 mg/kg, respectively.  Lead (990  mg/kg) was detected in composite sample COMP‐3 at a concentration above the DEQ Residential  PSRG and Industrial/Commercial PSRG of 400 mg/kg and 800 mg/kg, respectively.  Results of  sampling activities completed in April 2023, indicate elevated levels of lead are localized to  COMP‐3E aliquot locate in the northern portion of the Site.  No other metals were detected at  concentrations exceeding the DEQ PSRGs at the Site.     2) Depth of known or suspected contaminants (feet):  Concentrations of arsenic and lead were detected at concentrations above the DEQ PSRGs in  shallow soil (0‐2 feet below the ground surface [bgs])    3) Area of soil disturbed by redevelopment (square feet):  The entire Site is expected to be disturbed during grading (approximately 327,000 square feet).   Soil will be disturbed as part of leveling and grading activities to prepare the Site for  redevelopment.  A copy of the preliminary grading plan and cut‐fill analysis is provided as  Appendix B.         9  EMP Version 2, January 2021   4) Depths of soil to be excavated (feet):  Based on review of the grading plan, cut is generally planned in the area of the parking areas and  access driveways in the central portions of the Site and along Site boundaries.  Planned cut  depths are not expected to extend beyond 6 ft below current grade elevations.  Other discrete  areas may include deeper excavations for installation of deeper foundational footers, elevator  banks, utility banks, etc.  Soil generated during grading activities will be re‐used on‐Site as fill.   Remaining portions of the Site are planned fill areas.      5) Estimated volume of soil (cubic yards) to be excavated (attach grading plan):  Based on the grading plan and cut/fill analysis, cut during planned grading activities will generate  approximately 5,117 cubic yards of soil.  However, excess soil generated during redevelopment  of the Site will be re‐used on‐Site as fill material to the extent possible.  Copies of the most  recent grading plan, cut/fill analysis, and a Figure depicting sample locations relative to proposed  cut/fill areas are provided in Appendix B.      6) Estimated volume of excavated soil (cubic yards) anticipated to be impacted by contaminants:              As mentioned above, shallow cut is planned in limited areas at the Site and will generate  approximately 5,117 cubic yards of soil that is planned to be re‐used on‐Site.  Arsenic and lead  were detected at concentrations above the DEQ PSRGs in shallow soil samples collected at the  Site.  The locations of elevated arsenic and lead concentrations are in areas planned for fill.   Therefore, based on a review of the preliminary grading plan and soil sample analytical results, it  is not anticipated that excess soil impacted by contaminants will be excavated at the Site.    7) Estimated volume of contaminated soil expected to be disposed of offsite, if applicable:    Based on review of the preliminary grading plan and cut‐fill analysis report, excess soil generated  during grading activities is planned to be re‐used on Site as fill material.      In the unlikely event potentially impacted soil is encountered and cannot be re‐used on‐Site as  fill, it will be sampled and managed in accordance with the procedures described in the following  sections.        Part 1.A. MANAGING ONSITE SOIL  If soil is anticipated to be excavated from the Brownfield Property, relocated on the Brownfields  Property, or otherwise disturbed during site grading or other redevelopment activities, please  provide a grading plan that clearly illustrates areas of cut and fill (approximate areas & volumes are  acceptable, if only preliminary data available).      1) HAZARDOUS WASTE DETERMINATION:   a)

encountered issues during redevelopment of Brownfields Properties.  During construction activities, contractors may encounter unknown sub‐surface environmental  conditions (i.e., tanks, drums, or waste materials) that if encountered, will require management.   Prior to beginning Site work, H&H will attend a pre‐construction kick‐off meeting with the PD and  the redevelopment contractors to discuss the DEQ approved EMP and various scenarios when it  would be appropriate and necessary to notify the project environmental engineer of the discovery  of unknown subsurface features or potentially impacted media at the Site.    If such conditions are encountered during Site development activities, the procedures described  below will be used to direct environmental actions needed to adequately manage unknown buried  material and/or impacted soil in accordance with the EMP.  Sampling data for potentially impacted  soil or buried material and the disposition of impacted material will be provided to DEQ when the  data becomes available.    Underground Storage Tanks:   In the event a UST or impacts associated with a UST release are discovered at the Site during  redevelopment activities, the UST and/or UST related impacts will be addressed through the      28  EMP Version 2, January 2021   Brownfields Program.  DEQ Brownfields will be notified within 48‐hours of discovery of the UST.    A potential out‐of‐use 500‐gallon gasoline UST and one potential oil‐water separator/waste oil UST  may be located near the former 609 W. 28th Street Site building.  If uncovered during  redevelopment activities, the contents of the subsurface vessels (if any) will be removed by a third‐ party contractor for transport and disposal at an off‐Site facility permitted to accept the residual  fluids.  Upon removal of residual fluids, the subsurface vessel will be removed and transported off‐ Site for disposal or recycling.  Results of February 2022 Phase II ESA soil sampling activities (SB‐3, SB‐ 6, and SB‐7) did not identify impacts above the DEQ Residential PSRGs in the immediate vicinity of  the potential sub‐grade systems.  In the unlikely event obvious evidence of a release from the  systems is discovered during removal of the vessels, soil samples will be collected for laboratory  analysis at a rate consistent with current DEQ UST Section requirements to document potential  impacts that will be left in place.  Overburden soil will be used to backfill the excavation basin  during grading activities.  Additional impacted soil associated with the subsurface systems will be  managed in accordance with the Managing On‐Site Soil Section outlined above.  Disposal  certificates documenting the final disposition of the waste fluids (if any) and subsurface vessels will  be provided to DEQ Brownfields.      If an unknown UST is encountered, the UST will be removed, and the UST will be transported off‐ Site for disposal at a suitable facility.  If the UST contains residual fluids, the fluids will be sampled  for VOCs, SVOCs, and RCRA metals, and transported off‐Site for disposal at a suitable facility based  on the laboratory analytical results prior to removing the UST from the ground.  If a UST is  encountered that cannot be removed for structural or construction purposes (e.g., discovered  after footings or other foundational features for the proposed building have been constructed), it  may be abandoned in‐place with prior DEQ approval and construction will proceed.  Where  appropriate, the bottom may be penetrated before abandonment to prevent fluid  accumulation.  Impacted soil in the vicinity of the UST will be managed in accordance with the  Managing On‐Site Soil section outlined above in the EMP.      Sub‐Grade Feature/Pit:  If a sub‐grade feature or pit is encountered and does not require removal for geotechnical or  construction purposes, it will be filled with soil or suitable fill and construction will proceed.  Where  appropriate, the bottom may be penetrated before back filling to prevent fluid accumulation.  If the  pit has waste in it, the waste will be set aside in a secure area and will be sampled for waste  disposal purposes for TCLP VOCs, TCLP SVOCs, and TCLP metals and disposed off‐Site at a permitted  facility or the waste will be managed in accordance with the Managing On‐Site Soil section outlined  above in the EMP, whichever is most applicable based on the type of waste present.  If the pit must  be removed and the observed waste characteristics indicate the concrete may potentially be  contaminated, the concrete will be sampled and analyzed by methods specified by the disposal  facility.    Buried Waste Material – Note that if buried waste, non‐native fill, or any obviously filled materials is  encountered, the DEQ Brownfields Program must be notified to determine if investigation of landfill  gases is required:      29  EMP Version 2, January 2021   If excavation into buried wastes or impacted soils occurs, the contractor is instructed to stop work  in that location and notify the project environmental engineer.  The project environmental engineer  will review the materials and collect samples if warranted.  Confirmation sampling will be conducted  at representative locations in the base and the sidewalls of the excavation after the waste or  impacted soil is removed.  The confirmation samples will be analyzed for VOCs, SVOCs, and RCRA  metals.  Areas of impacted soil that remain at the Site after excavation is complete above the DEQ  Residential PSRGs will be managed pursuant to this plan.      Re‐Use of Impacted Soils On‐Site:  Please refer to description outlined in the Managing On‐Site Soil section (Part 1A) of the EMP above.
