6 PROJECT NARRATIVE UST SYSTEM REMOVAL OSFM SITE ASSESSMENT REPORT COMMUNITY CONSOLIDATED SCHOOL DISTRICT 181 THE LANE ELEMENTARY SCHOOL 500 NORTH ELM STREET HINSDALE, DUPAGE COUNTY, ILLINOIS IES PROJECT NO The following paragraphs provide a narrative description of the removal of one (1), 8,000-gallon heating oil underground storage tank (UST) system from the above referenced Community Consolidated School District 181 (CCSD 181) Lane Elementary School property, located at 500 North Elm Street, Hinsdale, DuPage County, Illinois. The UST was located near the southwest corner of the school property. Refer to Section 2, Exhibit A for UST Area/Soil Sample Location Drawing. R.W. Collins Company (Collins), a State-registered tank removal contractor, was retained by CCSD 181 to remove the UST. Integrity Environmental Services, Inc. (IES), an environmental consulting and engineering firm, was retained by CCSD 181 to provide environmental services for the UST system removal and to document the environmental condition of the surrounding soils, as required by the regulations of the Office of the State Fire Marshal (OSFM). Refer to Section 2, Exhibit B for the OSFM Removal documents (tank removal permit, tank destruction cert, and notification form). On July 5, 2017, using a back-hoe excavator, Collins begin the tank removal process by exposing the UST in the presence of the OSFM inspector, Mr. Bob Kowalski. The existing UST backfill materials (primarily a sand backfill with silt and clay native material) were stockpiled directly west of the tank excavation area. Once the tank was exposed and prior to its removal from the ground, excess product in the tank was pumped out by HazChem Environmental Corporation, a licensed special liquid waste hauler. A total of 5,500 gallons of product was removed from the UST. Refer to Section 2, Exhibit C for the liquid waste manifest. Prior to disturbing the UST, Collins displaced the oxygen in the tank so the interior could be tested for Lower Explosive Limit (LEL) levels. In the presence of the OSFM inspector, the LEL was recorded to be 0%. After testing and confirming the LEL, the remaining backfill material around the UST was excavated and the UST was lifted from the excavation and temporarily staged to the southwest of the tank excavation pit. The UST was then cut open for access and cleaned by Collins personnel. Once the tank had been cleaned, it was placed in a trailer for off-site disposal. 1 Integrity Environmental Services, Inc.

7 500 N Elm Street, Hinsdale, Illinois IES No As required, the OSFM inspector and the IES representative inspected the integrity of the 8,000-gallon heating oil UST and its excavation. The OSFM inspector, Mr. Kowalski, indicated that a petroleum release had occurred in association with this tank system due to the presence of petroleum odors in the backfill material. As a result, and as instructed by Mr. Kowalski, the IES representative contacted the Illinois Emergency Management Agency (IEMA) to obtain an incident number. IEMA subsequently assigned Incident No to the site and this tank removal. A small amount of backfill material (11.96 tons) from the bottom of the excavation that appeared to have a petroleum odor was loaded onto a small dump truck and sent to Waste Management s Laraway Landfill in Joliet, Illinois for disposal. Refer to Section 2, Exhibit C for the soil manifest. As required by Title 41 of the Illinois Administrative Code (IAC), Part of the OSFM regulations a Site Assessment was performed following the removal of tank by collecting soil samples for laboratory analysis. A total of eight (8) soil samples were obtained from the walls and floor of the excavation in accordance with the Illinois Environmental Protection Agency's (IEPA's) 20-foot grid sampling protocol. The soil samples were also screened with a photoionization detector (PID) for petroleum vapors. No elevated PID readings were detected in any of the soil samples collected. All soil samples were analyzed for Benzene, Toluene, Ethylbenzene, and Total Xylenes (BTEX) and Polynuclear Aromatic Compounds (PNAs) concentrations, the required indicator contaminant analysis for heating oil. The location of these soil samples and their designations can be viewed in Section 2, Exhibit B, UST Area/Soil Sample Location Drawing. The analytical results show several PNA compound concentrations in four (4) of the samples collected that were above the laboratory method detection limits, but all the concentrations were below the IEPA's most stringent Tier 1 Tiered Approach to Corrective Action (TACO) Soil Remediation Objectives (SROs). The analytical results do not support Mr. Kowalski's designation that a UST petroleum release occurred. Refer to Section 2, Exhibit D for the soil sample analytical data.

43 #=QL# Pace Analytical Services, LLC 1241 Bellevue Street - Suite 9 Green Bay, WI (920) QUALIFIERS Project: Pace Project No.: THE LANE DEFINITIONS DF - Dilution Factor, if reported, represents the factor applied to the reported data due to dilution of the sample aliquot. ND - Not Detected at or above adjusted reporting limit. TNTC - Too Numerous To Count J - Estimated concentration above the adjusted method detection limit and below the adjusted reporting limit. MDL - Adjusted Method Detection Limit. PQL - Practical Quantitation Limit. RL - Reporting Limit. S - Surrogate 1,2-Diphenylhydrazine decomposes to and cannot be separated from Azobenzene using Method The result for each analyte is a combined concentration. Consistent with EPA guidelines, unrounded data are displayed and have been used to calculate % recovery and RPD values. LCS(D) - Laboratory Control Sample (Duplicate) MS(D) - Matrix Spike (Duplicate) DUP - Sample Duplicate RPD - Relative Percent Difference NC - Not Calculable. SG - Silica Gel - Clean-Up U - Indicates the compound was analyzed for, but not detected. N-Nitrosodiphenylamine decomposes and cannot be separated from Diphenylamine using Method The result reported for each analyte is a combined concentration. Pace Analytical is TNI accredited. Contact your Pace PM for the current list of accredited analytes. TNI - The NELAC Institute. LABORATORIES PASI-G PASI-K Pace Analytical Services - Green Bay Pace Analytical Services - Kansas City BATCH QUALIFIERS Batch: [M5] ANALYTE QUALIFIERS 1q B P3 S4 A matrix spike/matrix spike duplicate was not performed for this batch due to insufficient sample volume. The methods baseline separation for isomers pairs in the Initial Calibration or Continuing Calibration Verification (CCV) was less than the expected 50% valley to baseline. No further action was taken for this method variation. The two compounds are still being reported as individual isomers and not a combined total, since there is separation between the two isomers. Analyte was detected in the associated method blank. Sample extract could not be concentrated to the routine final volume, resulting in elevated reporting limits. Surrogate recovery not evaluated against control limits due to sample dilution.
