Title 33 › Chapter CHAPTER 26— - WATER POLLUTION PREVENTION AND CONTROL › Subchapter SUBCHAPTER III— - STANDARDS AND ENFORCEMENT › § 1326
Regulators may set limits on how hot a facility can make the water it discharges so that local shellfish, fish, and wildlife are protected and can keep living and reproducing. If the owner or operator, after a public hearing, proves that a proposed temperature limit is stricter than needed to protect a balanced, native population, the Administrator or the State may set a limit that still ensures protection, taking into account how heat interacts with other pollution. Any rule under sections 1311 or 1316 must require cooling water intakes to be located and built using the best technology available to reduce harm. If a facility with a thermal discharge is changed after October 18, 1972, and the changed facility meets the limits under section 1311 or the tighter limits under section 1313 that protect the native population, it cannot be made to meet stricter temperature limits for ten years after the change or for the depreciation/amortization period under sections 167 or 169 of title 26, whichever ends first.
