Title 33 › CHAPTER 26 — WATER POLLUTION PREVENTION AND CONTROL › SUBCHAPTER III — STANDARDS AND ENFORCEMENT › § 1326
The government must limit how much heat industrial discharges put into rivers, lakes, and coastal waters so native shellfish, fish, and wildlife can survive and reproduce. After a public hearing, if a plant owner proves a proposed heat limit is stricter than needed to protect those populations, the federal or state regulator can set a limit that still ensures protection, and must consider how heat interacts with other pollution. Rules also require cooling-water intakes to be placed and built using the best available technology to reduce harm. If a facility was modified after October 18, 1972 and the modified facility meets the required protective heat limits, it cannot be forced to meet tougher heat limits for ten years after the modification or until its tax write-off period ends, whichever comes first.
