reliable statewide water supply

Review Specific Comments
• Outdated Standard Used For Ammonia
— 1999 vs. 2013 Freshwater Ammonia Standard
—Sac Regional ammonia reduction reference
• No Agricultural Contribution Of
Ammonia In The Delta
— Study assumptions and modelling assign
ammonia loading to POTWs
— Findings and mitigations could change if
agricultural ammonia inputs evaluated
Review Specific Comments
• Insufficient Evaluation Of Selenium (Se)
— Updated Data From Tetra Tech TMDL Study
— Inconsistent Use Of Se Data
— Monitoring Stations Used For Modelling
• Tidal influence
— Defer Se Mitigation To Future TMDL and Other
Control Strategies
• North Bay Se TMDL with delta sources
