Title 33 › Chapter CHAPTER 26— - WATER POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER III— - STANDARDS AND ENFORCEMENT › § 1317
Creates and keeps a national list of toxic pollutants starting from December 27, 1977, using the chemicals named in a specific Committee print. The Administrator must publish that list within 30 days and can later add or remove pollutants. When deciding what to add or remove, the Administrator must consider how toxic the pollutant is, how long it lasts, how it breaks down, whether affected organisms live in the water, how important those organisms are, and how the pollutant harms them. Each listed pollutant must have limits on how much can be discharged based on the best available technology that is economically achievable for the type of source. The Administrator can also propose stricter standards or bans. There must be at least 60 days for written comments and a public hearing if someone asks within 30 days of the proposal. A final standard must be issued within 270 days of the proposal. Limits for the original list had to be set as soon as possible after December 27, 1977, but no later than July 1, 1980; limits for later additions must be set as soon as possible after they are listed. Standards must be reviewed at least every three years and must give an ample margin of safety. The Administrator must name which kinds of sources the rules apply to, may include dredged-material disposal after talking with the Secretary of the Army, and should consult advisory groups, States, experts, and federal agencies before publishing. New standards take effect no later than one year after they are issued, but the date can be delayed up to three years for a group of sources if meeting the standard in one year is not technologically possible. The Administrator must also issue pretreatment rules for pollutants put into public sewage treatment plants. Proposed rules were required within 180 days after October 18, 1972, with final rules issued within 90 days after proposal and after chance for a hearing. Pretreatment rules must prevent pollutants that the plant cannot treat or that would interfere with its operation, and they must give sources up to three years to comply. If a public treatment plant removes a pollutant so that the treated discharge meets the applicable limits and does not interfere with sludge use or disposal, the plant owner may adjust source pretreatment requirements. The Administrator must update pretreatment rules as technology changes, must name the source categories covered, and must set pretreatment rules for new sources at the same time new-source performance rules are issued. Once any standard or pretreatment rule is in effect, it is illegal to operate in violation of it. For an existing facility using an approved innovative treatment system, a public treatment plant owner may grant up to a 2-year compliance extension if the Administrator finds the system could be useful industrywide and the Administrator (or the State with the Administrator’s involvement) agrees that the extension won’t make the plant violate its permits.
