UNITED STATES ENVIRONMENTAL PROTECTION AGENCY WSG41A Date Signed: May 18, 1989 Revised: July 1998 Revised by: Judith Fraser MEMORANDUM SUBJECT: Lab Certification for Lead Contamination Control Act (LCCA) FROM: Arthur H. Perler, Chief Science and Technology Branch, CSD TO: Jeanne Briskin Regulatory Impact Analyst, ODW THROUGH: Joseph A. Cotruvo, Ph.D., Director Criteria and Standards Division, ODW As we discussed on the phone on May 17, 1989, here is some draft language for your response to paragraphs 1 and 3 on page 2 of Rosov's letter. Q. 1 The LCCA requires that testing be done in laboratories approved by the State. EPA does not intend to write laboratory certification regulations under the LCCA. Rather, EPA recommends that States base approvals under the LCCA upon their existing laboratory certification program for lead compliance samples under the Safe Drinking Water Act. States should examine each laboratory's current certification status and performance on recent low-level PE-samples provided by EPA, or equivalent samples. Q. 2 In March 1997, EPA published the "Manual for the Certification of Laboratories, Analyzing Drinking Water Criteria and Procedures, Quality Assurance" (4th Edition). This manual attempts to address past difficulties resulting from significant differences in State laboratory certification programs.
