Changes to 40 CFR part 136 Analytical Methodologies as of April 2012: new method approval and old methods have been dropped for the chemical analysis of wastewater. EPA’s revised analytical tables reflect new technologies with instrument advancements.
Approved methods include the most current Standard Methods for the Analysis of Water and Wastewater testing methods . 40 CFR now lists Standard Methods as 4500 CL B -2000. The -2000 is the year Standard Methods last approved the method and has been approved in the latest MUR. Section A of all method editions will list (in fine print) the approval date. Laboratories should review their methods and identify which methods are approved for compliance analysis. Also, the 22nd Edition of Standard Methods has also been approved and is listed as 4500 CL B -2011 (see EPA approval letter).
140 CFR 136.7: Essential Quality Assurance and Quality Control (QA/QC): Regardless of the publisher, edition, or source of an analytical method approved for compliance monitoring, analysts must use suitable QA/QC procedures, even if it is referenced in other sources or documents. These records must be kept in-house as part of the method testing documentation.
OAC 252:303 TNI Laboratory Accreditation implementation has been extended to January 2016. This will allow the DEQ time to review the current language.
