Perhaps the most widely employed method of assessing potential impacts upon ecological systems has been the array of effluent toxicity tests used in conjunction with National Pollution Discharge and Elimination System (NPDES) permits. These tests are now being required by a number of states... 

The National Pollutant Discharge Elimination System (NPDES) permits were based on effluent limitations in a staggered fashion to achieve the goals set forth in the 1983 CWA amendments. The permits are issued to individual wastewater treatment plants to reduce the number of pollutants released into nearby waterways. The permits contain standard conditions applicable to all POTWs, site-specific constraints, compliance monitoring, and reporting requirements. 

An NPDES permit can be issued by EPA or by a state that has received EPA permitting approval. As of 1996,40 states and territories had received EPA s approval. States and territories that are not authorized to administer the NPDES program are Alaska, Arizona, District of Columbia, Idaho, Louisiana, Maine, Massachusetts, New Hampshire, New Mexico, the Pacific Territories, Puerto Rico, and Texas. For these states and territories, the 10 EPA Regional Offices will issue and administer the NPDES permits. The permit process is elaborate and requires extensive information and numerous steps. First a number of forms need to be completed to provide information about the facility, its operation, and the nature of the discharges. This is followed by a period of discussion between EPA and the discharging facility, and the draft permit is announced for comments from the public for 30 days. Once the comments are reviewed, responded to, and implemented, then the final NPDES permit is issued.
