CMe ASSOCIATES Mr. Leonard R. Lepore, PE April 18, 2018 Municipal Engineer/Director of Public Works Page 5 of 10 Re: Fire House No. 4, 280 Pleasant Valley Way— LSRP Services Orange will hire the contractor to excavate, remove, dispose and backfill with certified clean fill material. Approximately, 150 tons of potential contaminated soil located under the existing asphalt surface. The proposed excavation area is approximately 300 square feet and up to a maximum depth of 15 feet below ground surface. Field screening techniques will be performed in accordance with the NJDEP Technical Requirements for Site Remediation (N.J.A.C. 7:26E) to determine the potential presence of impacted materials. The field screening will include evaluating the extracted materials for the potential presence of volatile organic compounds using a photoionization detector (PID). If visual observations and/or field screening measurements indicate the presence of contamination, the observed contamination will be removed from the excavation as part of the 150-ton total. The LSRP representative will collect post-excavation soil samples upon removal of the observed contamination in accordance with the NJDEP Technical Requirements for Site Remediation (N.J.A.C. 7:26E). Post-excavation sample locations will be selected in accordance with the Technical Requirements for Site Remediation (N.J.A.C. 7:26E). Sample locations and frequency will be at a minimum, sufficient to satisfy the requirements of the applicable Technical Requirements for Site Remediation (N.J.A.C. 7:26E). The soil samples will be analyzed for EPA Target Compound List volatile organic compounds (TCL VO+15) with a library search of the 15 highest Tentatively Identified Compounds (TICs) and tertiary butyl alcohol (TBA). The contractor will have appropriate equipment (e.g., vacuum truck) to remove, store and dispose of any free-phase product and contaminated groundwater encountered in the excavation. The excavated soil will be temporarily stockpiled at the Site, and will be sampled for waste classification, loaded and transported to an approved off-Site facility for disposal. The excavated soil will be sampled by CME for classification (hazardous/non-hazardous) according to RCRA regulations. For the purpose of this proposal and budgeting purposes, CME anticipates collecting and analyzing one soil sample for

The excavated soil will be disposed of at a licensed facility and the excavation will be backfilled with certified
