National Pollutant Discharge Elimination System (NPDES) regulations are found in 40 CFR Parts 122 and 125 and in Arkansas Regulation 6 "Regulations for State Administration of the National Pollutant Discharge Elimination System (NPDES), effective April 16, 2004".

The NPDES program requires permits for the discharge of "pollutants" from any "point source" into "waters of the United States."

When "quantitative data" for a pollutant are required, the applicant must collect a sample of effluent and analyze it for the pollutant in accordance with analytical methods approved under 40 CFR Part 136. General testing requirements are dependent upon if an organization is applying for a new permit, meeting the requirements of an existing permit, or undergoing permit renewal.

Listed are a number of general permits, tables and forms for which analytical testing is frequently requested. This information is provided as guidance only. The applicability of these forms to a given industry/site should be discussed with the appropriate regulatory agency.
