NJ 07052 Re: PROPOSAL FOR ENVIRONMENTAL SERVICES ADDITIONAL LABORATORY ANALYSES TOWNSHIP OF WEST ORANGE MULTI PARK DEVELOPMENT LAFAYETTE PARK BLOCK 61, LOT 27 PARK AVENUE AND MAIN STREET WEST ORANGE, NEW JERSEY NJDEP’s PROJECT NO. 0722-17-035 MATRIX NO. P17-707 Dear Mr. Lepore: As requested, Matrix New World Engineering, Land Surveying and Landscape Architecture, P.C. (Matrix) is pleased to provide this proposal for the additional laboratory analyses for the above-referenced Site. Based on a review of the data, there are several detections of metals in soil above the New Jersey Department of Environmental Protection (NJDEP’s) default impact to groundwater soil remediation standards. Some of these metals including aluminum, manganese and silver are considered secondary metals, are not of concern, and do not require further sampling or analysis. However, there are several metals, specifically beryllium, lead, and mercury, that require further laboratory analysis to calculate a site-specific impact to groundwater soil remediation standard (SS-IGWSRS). If a SS-IGWSRS is successfully calculated, then no further investigation, remediation or NJDEP reporting is required. Therefore, to calculate a SS-IGWSRS, the following samples will be additionally

. If a SS-IGWSRS is successfully calculated, then no further investigation, remediation or NJDEP reporting is required. Therefore, to calculate a SS-IGWSRS, the following samples will be additionally analyzed on an expedited three-day turnaround for specific metals noted below utilizing the Synthetic Precipitation Leaching Procedure (SPLP). 6(1)/1.5-2.0 JC64495-4 (SPLP beryllium, SPLP lead and SPLP mercury) 6(2)/4.5-5.0 JC64495-1 (SPLP beryllium, SPLP lead and SPLP mercury) 6(3)/3.0-3.5 JC64495-2 (SPLP beryllium, SPLP lead and SPLP mercury) 6(4)/3.0-3.5 JC64495-3 (SPLP beryllium, SPLP lead and SPLP mercury) Total Costs Not to Exceed ....................................................................................................................$690.00 ASSUMPTIONS AND EXCLUSIONS This proposal is based on the following assumptions:  Samples will be analyzed on a three-business day turn around;  The calculation for the SS-IGWSRS will be determined utilizing NJDEP’s SPLP Spreadsheet (V3.1); and  All external costs will be charged at cost plus 15%.
