15

OTC – Why?

16(modified from Raimondi)

(> 3/8 inch)

17

Impacts from Once-through Cooling

Impingement in intakes: adult fish and other large organisms, including (e.g., turtles)

Entrainment through the plant: larval fish and other plankton, 100% mortality

18

Impinged fish Entrainment: fish larvae

Traveling (intake) screen Impinged organism disposal

19

OTC – What?

Federal and State Law

- Section 316(b) CWA

Federal Regulation

- 40 CRF 125.90(b)

State Policy (ETA: June 2008)

20

OTC – What?

Permitting authorities must develop case-by-case best professional judgment controls for existing facility cooling water intake structures that reflect the best technology available for minimizing environmental impact

[40 CFR 125.90 (b)]

Existing Coastal Power Plants

19 active plants with approximately 16 billion gallons per day sent through the once-through cooling water systems.

23

OTC – Costs?

Will depend upon approach taken by the State Board

State Board welcomes constructive input

Make sure they are aware of plant-specific facts

24

OTC - Coordination

State Board and ISO State Board and CEC/PUC State Board and

Stakeholders Understanding that rollout

schedule must take into account reliability
