ASSOCIATES Mr. Leonard R. Lepore, PE April 18, 2018 Municipal Engineer/Director of Public Works Page 3 of 10 Re: Fire House No. 4, 280 Pleasant Valley Way— LSRP Services management to oversee the closure of the two USTs, collection of post- closure/excavation soil sampling and backfilling activities. The on-Site services will include: . Visual observation of the two UST systems and piping during and subsequent to closure to verify the integrity of these structures in order to evaluate the potential that previous leaks and/or uncontrolled product discharges may have occurred. . Implement field screening methods in accordance with the protocols detailed in the NJDEP Field Sampling Procedures Manual (August 2005). 7 In the absence of obvious petroleum product impacted areas, CME will initiate the post-closure soil sampling and analysis protocols specified in the NJDEP Technical Requirements for Site Remediation (N.J.A.C. 7:26E-3) for the two USTs and piping (one [1] sample required per 15 linear feet of product piping) and conform to NJDEP closure obligations and LSRP direction. Soil Sampling at 2,500-gallon capacity diesel fuel UST: Nine (9) soil samples will be collected based on field observation and field screening to document UST/piping closure. Soil samples will be analyzed for Extractable Petroleum Hydrocarbons (EPH) with a contingency for 2- methylnaphthalene and naphthalene for 25% of all soil samples that exhibit EPH impact greater than 1,000 parts per million. Per NJDEP QA/QC requirements, one (1) field blank and one (1) trip blank will also be submitted for laboratory analysis. Soil Sampling at 1,000-gallon capacity unleaded gasoline UST: Eight (8) soil samples will be collected based on field observation and field screening to document UST/piping closure. The soil samples will be analyzed for EPA Target Compound List volatile organic compounds (TCL VO+15) with a library search of the fifteen (15) highest Tentatively Identified Compounds (TICs) and tertiary butyl alcohol (TBA). All soil samples will be submitted to a NIDEP-certified analytical laboratory for analysis to evaluate the potential that discharges from the subject UST systems have impacted the
