EPA 316.B Regulation Change

What is the purpose of the change?

To create a national standard for the Location, Design, & Construction of Cooling Water Intact Structures (CWIS) to minimize impact on aquatic life.

- Reduce Fish Impingement Mortality – 80 to 95%
- Reduce Fish Entrainment Mortality – 60 to 90%
- Minimize Adverse Environmental Impact ( AEI )

When will the purposed changes take place?

Phase II Regulations - Instituted
Phase III Regulations - Nov 1, 2004

Who will be impacted by the changes?

What about facilities using less than 50 MGD?

These facilities will fall under Phase III of 316b, which is scheduled for introduction at the end of calendar year 2004.

Key considerations?

- CWIS will be limited to intake velocities of .5 fps or must meet the Fish Impingement Criteria
- CWIS for all NEW plants shall be located outside of sensitive bio-logical areas
- Technologies that minimize fish impingement and entrainment shall be implemented for any CWIS located inside sensitive biological areas

Conclusion: Facilities with CWIS need to plan on using the Best Technology Available (BTA) to ensure compliance.

1) Steam Electric Generating Plants
2) Manufacturing sectors with substantial CW use.

316b Phase II Rule applies to ALL large power plants and industrial facilities that use 25% of their intake flow for cooling and pass 50 million gallons per day or greater.
