DocuSign Envelope ID: F5386E96-142E-43B7-B563-2857F678D6B3 <br /> Mr. Bruce Woody <br /> September 24, 2019 <br /> Page 2 of 3 <br /> Deliverables. DAA will provide one digital copy of the report to the OCSWM (Adobe Acrobat or functional <br /> equivalent). <br /> Exclusions. Deliverables do not include digital source files used in preparing the report (for example, MS <br /> Word, MS Excel, AutoCad files). <br /> Terms and conditions. Services will be provided in accordance with the content of this proposal and an <br /> existing Agreement between OCSWM and Draper Aden Associates (dated February 22, 2017). <br /> Background. During 2007 NCDEQ promulgated Solid Waste Section Limits for listed organic and inorganic <br /> constituents, and for most general chemistry parameters. The SWSL values were established in lieu of <br /> laboratory Practical Quantitation Limits (PQLs), and were intended to function as the laboratory reporting <br /> limits. In addition, many of the facility background concentrations were by default, the SWSL values, which <br /> was a benefit to most facilities. <br /> The use of the SWSL values was subsequently discontinued (memorandum dated May 29, 2018), and <br /> reporting limits are now laboratory specific (often, at a concentration much lower than the previous SWSL), <br /> which does not benefit most facilities. As a result, we recommend that the facility establish site-specific <br /> background concentrations for inorganic constituents to evaluate potential benefits to the facility as site <br /> specific background concentrations in lieu of Groundwater Quality Standards. <br />
