Effluent guidelinesEffluent guidelines are national standards for wastewater discharges to surface waters and publicly owned treatment works (municipal sewage treatment plants). We issue effluent guidelines for categories of existing sources and new sources under Title III of the Clean Water Act. The standards are technology-based (i.e. they are based on the performance of treatment and control technologies); they are not based on risk or impacts upon receiving waters.
Proposed and final rulesIncluded on these pages are Federal Register notices of proposed and final rules, supplemental notices, pre-proposal documents, background information, draft industry questionnaires, public meeting notices, development documents and other supporting documents, and related documents. The date of the latest update to each guideline is shown in parentheses.
