Effluent Guidelines

Pesticide Chemicals Effluent Guidelines

EPA promulgated initial Effluent Guidelines and Standards for the Pesticides Chemicals Category in 1978, and revised the regulation in several actions through 2007. The regulation (40 CFR Part 455) provides effluent limitations and standards for four subcategories and test methods for certain pesticides and processes. The Effluent Guidelines and Standards are incorporated into NPDES permits for direct dischargers, and permits or other control mechanisms for indirect dischargers (see Pretreatment Program).

Facilities Covered

The Pesticide Chemicals regulation applies to the following subcategories:
  1. Organic Pesticide Chemicals Manufacturing
  2. Metallo-Organic Pesticide Chemicals Manufacturing
  3. Pesticide Chemicals Formulating and Packaging
  4. Repackaging of Agricultural Pesticides Performed at Refilling Establishments
Subpart D provides references to analytical methods.
