What Are WE Trying to Accomplish?
WE = Water Board, Agriculture, Stakeholders
Protect water quality for current and future generations
Ensure any new requirements are consistent with sustaining agriculture in the Central Valley
Learn and adapt as we move forward
3
Direction from Central Valley Water Board, June 2011
Tailor approach to specific geographic areas or commodities
Include requirements to protect surface and groundwater quality
Continue with Coalitions (third-parties) as lead to assist growers w/compliance
Use General Waste Discharge Requirements (WDRs)

Geographic Areas/Commodities Addressed by WDRs
Long-term Irrigated Lands Regulatory Program Scope
Irrigated Lands Regulatory Program (ILRP) Includes commercial operations, managed
wetlands, nurseries Surface water discharges surface return flows, storm runoff, tile
drainage Groundwater discharges Fertilizer/pesticides moving down soil profile,
well head, or backflow5

Agenda Item 13 8Central Valley Water Board Meeting
June 2012
About 642,500 irrigated acres (62%) are in groundwater vulnerable areas

What’s Next?
Implementation began with the adoption of the Eastern San Joaquin River Watershed Order
Orders for the Tulare Lake Basin and Growers not in a Coalition coming up in next few months
