<br />3) Units of measurement; <br />' 4) Short method title and test method number, with reference source <br />for the method; <br />' S) Limits for standards, upper and lower, as a percentage of the <br />actual value in the standards; <br />' 6) Limits for analytical spikes, upper and lower, as a percentage of <br />the actual value; and <br />' 7) Upper limit of error on duplicate analyses. <br />' 8. Please indicate the source of Appendix D, Appendix F and App9ndiz G <br />RESPONSE: Appendix D, as above; Appendix F, State of New Jersey Administrative Code, <br />' NJAC7:9-6.1 et. seq.; Appendix G, United States EPA SW-84b Test Methods. <br />9. In [his Protocol, as in any, the operator should recognize that analytical labs <br />need to be checked periodically and to do so requires arr establi.thed procedure. <br />Bartle Mountain should have samples wilt known quantities Of annlytes and <br />' shordd submit these periodically for analyses along wilt od:er analyses. In <br />addition, the operator should prepare sa»tples for "Rott»d Robin "analyses, itttra- <br />laboratory comparisons and routine sample duplication. EYCept far some <br />' provision for field duplications, there me few provisions for assuring that the <br />convnercial labs (the Vendors) will supply consisternly reliable analyses. Battle <br />Mountain should provide for some degree of quality assurance front their vendors, <br />either through their own lab personnel or through a third parry who is familiar <br />wit/t these techniques. <br />' RESPONSE: The Protocol document calls for the routine collection of field duplicates to check <br />the analytical laboratory's ability to replicate results and, as Sectipn 2.1.13 of the <br />Protocol document states, all samples analyzed by the laboratory will follow the <br />' laboratory QA/QC controls that are necessary Tor an EPA-certified laboratory. <br />This includes documentation of the calibration of the instrumentation, analysis for <br />interference effects and spike matrix analyses. These are accepted EPA-protocols <br />' for providing QC checks on the analytical laboratory's accuracy, In fact, these <br />standardized methodologies allow EPA to compare various lab's results since they <br />all have to meet the same QA/QC protocols. Therefore, these procedures are <br />' designed to demonstrate quality control through the analytical procedure and these <br />data can be provided to CMLRD if desired. <br />' -5- <br /> <br /> <br />
