MALE ASSOCIATES 1.0 INTRODUCTION, PURPOSE & SCOPE This document constitutes the Site Characterization Work Plan (SCWP) for the Hudson Valley Regional Airport site (the “Site”) located at 18 Griffith Way in the Town of Wappinger, Dutchess County, New York. The Site is approximately 510.8 acres in size and is identified with tax number 135689-6259-03-225301-0000 on the Town of Wappinger tax maps. A Site Location Map, Site Map – Sampling Locations, and Site Map – Sampling at AAG Hangars are included as Figures 1, 2 and 3. The New York State Department of Environmental Conservation (NYSDEC) has classified the Site as a potential inactive hazardous waste disposal site (P-Site #314129) as a result of the presence of combined perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) at concentrations in one of the potable drinking water supplies at the Site above the health advisory value of 70 parts per trillion, set by the United States’ Environmental Protection Agency (USEPA) in May 2106. This SCWP was developed in accordance with NYSDEC DER-10 Technical Guidance for Site Investigation and Remediation (May 2010) (DER-10) and 6 NYCRR 375 Environmental Remediation Programs (December 14, 2006). In addition, this SCWP incorporates the specific requirements for this site characterization as set forth in the NYSDEC’s comment letter dated August 21, 2018 and April 12, 2019. The NYSDEC letters are included as Exhibit 1. 1.1 Background By letter dated September 15, 2017, NYSDEC informed Dutchess County that NYSDEC had classified the Site as a “P-site” based on the detection of perfluorinated compounds in a water supply well located on the Site and low concentrations in nearby off-site water supply wells. The water samples were collected by the New York State Department of Health (NYSDOH). This letter also stated that an investigation was required to be conducted in accordance with NYSDEC’s technical requirements for a site characterization. The NYSDEC letter and results of the NYSDOH sampling are included as Exhibit 2. 5 C.T. MALE ASSOCIATES 1.2 Purpose The purpose of this SCWP is to establish an environmental baseline and conceptual model for the Site with the intent of acquiring sufficient data for determining if further Site investigation is necessary. 1.3 Scope of Work The following scope of work is proposed to develop an initial environmental baseline and conceptual model for the Site. • Conduct a Records Search in accordance with Appendix 3A of DER-10 to identify potential Areas of Concern (AOC). The records search involved the review and summation of available records for the Site, a Site reconnaissance and interviews with pertinent Site personnel knowledgeable of past and present Site operations. To the extent that they were available, records reviewed for the Site generally included historic land usage; past and present industrial/commercial operations; past and present usage/generation of hazardous materials/wastes, petroleum products, firefighting foam and aqueous film forming foam (AFFF); past and present storage containers, tanks and bulk storage areas; past and present environmental permits, reports, work plans and remedial actions; past and present administrative, civil and criminal enforcement actions for alleged violations of environmental law; and areas of historic fill placement within the Site. The Records Search Report was submitted for NYSDEC review and comment in May 2018. • Conduct a Site Characterization (SC) investigation
