The Regulation
- The Environmental Protection Agency is proposing regulation to reduce harm to aquatic organisms caused by cooling water intakes structures at manufacturing facilities and offshore oil and gas extraction facilities.
- EPA has previously regulated cooling water intake structures at new facilities (Phase I) and at large power plants (Phase II).
Our Findings
- While authorized by the Clean Water Act and a consent decree to regulate these facilities, EPA is not required to take regulatory action unless it finds "adverse environmental impacts."
- EPA has offered no evidence of "adverse environmental impacts" at these facilities, but rather assumes impacts based on dissimilar conditions at a few large power plants.
- Impacts on aquatic organisms depend on local conditions, and existing permitting procedures under the Clean Water Act are better able to address those impacts.
By the Numbers
- EPA's estimates of the costs of its proposed approach outweigh the benefits by between $14.7 million and $49.3 million annually.
- While EPA argues there are unquantified benefits that could justify the costs, our analysis suggests that EPA's costs may be understated and benefits overstated.
Recommendations
- Rather than issuing this regulation, EPA should take final regulatory action that clarifies state permitting agencies' authority to address any identified problems at these facilities.
- EPA should explicitly authorize non-technology based alternatives to compliance, including stocking populations of species that may be harmed.
