Are the methods promulgated under Part 455 for pesticide active ingredients valid for the NPDES program and pretreatment programs under Part 136?
Yes. Language in 40 CFR 403 and 136 allows for analytical methods found in Part 136, Section 304(h) of the Clean Water Act, or that are approved by the Administrator (403.12(g)(4) and 136.4, 136.5). Therefore, although the Part 455 regulations have not been incorporated into Part 136, the Administrator has approved these analytical methods by signing the Pesticide Manufacturing Effluent Limitations Guidelines and Standards (58 FR 50637; September 28,1993).
