CV-SALTS – Managing Salt and Nitrate in the California Central Valley

For Permittees

Two Options Available for Salt Compliance

While the Phase 1 Prioritization & Optimization Study is underway (10 to 15 years), there are two options available for salt compliance. Under both options, existing salt management and monitoring requirements will continue.

Option 1: Conservative Individual Option

Individual permittee is responsible for reducing salt accumulation.

Stringent numeric water quality permit limits apply based on protecting the agricultural and/or municipal beneficial uses.

P&O Study participation is optional.

Option 2: Alternative Cooperative Option

Permittee elects to join region-wide P&O Study with fellow permittees.

Payment of an annual fee to support P&O Study is required.

Current permit performance levels must be maintained, while more stringent requirements are deferred during Phase I.

The P&O Study will help to determine the next permitting options for Phase II.

Benefits of the Alternative Cooperative Option:

  • Opportunity to participate and inform P&O Study process and analysis, including development of Phase II.

  • Avoid more stringent and costly permitting requirements tied to the Conservative Individual Option during Phase I.

  • Likely less costly than Conservative Individual Option requirements.

  • Cooperative approach can aid achievement of long-term regional salinity goals.
