This regulatory action would amend "Guidelines Establishing Test Procedures for the Analysis of Pollutants" at 40 CFR part 136 to approve test procedures (analytical methods) for use by testing laboratories and others for water monitoring. These test procedures must be used to implement the NPDES program unless EPA has approved the use of an alternate procedure. The regulation would also revise, clarify, and correct errors and ambiguities in existing methods and the water monitoring regulations.
