This presentation described Clean Water Act Analytical Mehods; Methods Update Rule - 2016 promulgated by EPA. EPA is promulgating changes to analytical test procedures that are used by industries and municipalities to analyze the chemical, physical, and biological components of wastewater and other environmental samples that are required by regulations under the Clean Water Act. The changes include revised methods published by EPA and voluntary consensus standard bodies voluntary consensus standards bodies, such as ASTM International and the Standard Methods Committee. EPA is adding certain methods reviewed under the alternate test procedures (ATP) program to 40 CFR Part 136 and clarifying the procedures for EPA approval of nationwide and limited use ATPs. Further, EPA is revising the procedure for determination of the method detection limit (MDL)

These revisions:
• provide increased flexibility to the regulated community
• improve data quality
• update the methods, to keep current with technology advances
• address laboratory contamination issues related to the MDL and better account for intra-laboratory variability.

The Administrator, Scott Pruitt, signed the final rule on August 7, 2017, and EPA is submitting it for publication in the Federal Register (FR). While we have taken steps to ensure the accuracy of this Internet version of the rule, it is not the official version of the rule for purposes of compliance. Please refer to the official version in a forthcoming FR publication, which will appear on the Government Printing Office's FDsys website (http://fdsys.gpo.gov/fdsys/search/home.action) and on Regulations.gov (http://www.regulations.gov) in Docket No. EPA-HQ-OW-2014-0797.
