Overview of Proposed Requirements

• Three Subcategories
  – Flow Through
  – Recirculating
  – Net Pens
• Requirements apply to facilities in these
  subcategories with annual production
  >100,000 pounds
   Flow Through Requirements
• Tiered Requirements
  – Medium sized: 100,000 up to 475,000 lb/year
  – Large sized: 475,000 lb/year and up
       Medium Flow Through
• Numeric limits: TSS 11 and 6 mg/L
• BMP plan
  – ensure proper operation & maintenance
  – material storage
  – removal and proper disposal of mortalities
• Ensure staff are familiar and trained in
  BMPs
• Certify BMP plan
         Large Flow Through
• Numeric Limits: TSS 10 and 6 mg/L
• BMP plan adds
  – the escape of non-native species
• Reporting for drugs & chemicals
• Staff training
• Certify
 Flow Through Segregated Discharges
• Numeric Limits for Off-line discharge: TSS
  – Medium 87 and 67 mg/L
  – Large 69 and 55 mg/L
• BMP plan adds solids controls on bulk
  discharge
  –   solids removed in water treatment
  –   excess feed
  –   high level of particulates or phosphorus in feed
  –   raceway cleaning
BMP Alternative Compliance Provision

• Develop and implement a BMP plan to
  address solids in lieu of monitoring for TSS
  limits
• Subject to permit authority approval and
  determination that BMPs will achieve
  numeric limits
