Storm Water Story (being rewritten as we sit here!) Storm water management plays vital role in quality and availability of CA water CA’s growing population and climate change increase pressure on water quality and supply Effective storm water management becomes even more urgent
The Next Chapter Continue the shift from ‘end of pipe’ treatment to storm water as resource Innovative, multiple-benefit approaches to achieve tangible results in terms of both water quality and water supply
Storm Water Strategy Initiative Phase 1 Storm Water Strategy Initiative Phase 1 In May 2014 SWSI Team rolled out a list of “discussion starters,” or potential issues and Water Board actions organized into three element areas: 1. Utilize Storm Water as a Resource 2. Remove Storm Water Pollutants by True Source Control 3. Improve Storm Water Program Overall Efficiency and Effectiveness
Sustainable Groundwater Management Legislation Local Tools and Authorities Local Agency Formation and Planning Requirements State Assistance, oversight, and intervention AB 1739 (Dickinson) SB 1168 (Pavley) SB 1319 (Pavley)
Local Agency Formation and Planning Groundwater Sustainability Agencies (2017) One or more cooperating agencies Basins to be managed by a single agency or coordinated agencies Prepare and adopt Groundwater Sustainability Plans (2020-2022) Consider local planning projections Measurable objectives & interim milestones Annual reports (groundwater extractions, total water use, and change in groundwater storage) Achieve sustainability (20 years after plan)
Local Tools and Authorities Metering and monitoring Permit and pumping fees Pumping limits/groundwater allocation Enforcement (including fines) Well spacing
State Assistance, Oversight and Intervention DWR to assist locals and will publish estimates of water available for replenishment and BMPs DWR to develop regulations defining components of a GSP (2016) DWR will evaluate and assess a GSPs The State Water Board may develop an interim plan when: there is no GSA (2017) a GSP is not completed(2020) the GSP is inadequate or not implemented to achieve sustainability and there is a condition of long term overdraft or significant depletion of interconnected surface waters (2020, 2022, or 2025).
Other Provisions Water Board fee authority Requires reporting to State Water Board when no GSA Increased coordination of groundwater management and land use planning Off ramp for well managed and adjudicated basins Related---Water Bond allocates $900M to the State Water Board for groundwater cleanup and management
SB 4: Oil and Gas Monitoring Unit New Unit in Division of Water Quality New positions at Regional Boards 3, 4, and 5 Current activities: Develop MOU with DOGGR for well stimulation regulation Review operator submitted groundwater monitoring plans Review operator submitted requests for written concurrence Develop model criteria for groundwater monitoring by July 2015 Implement Regional Groundwater Monitoring by Jan 2016 Consult with DOGGR on their final regulations for well stimulation Manage list of designated contractors for property owner requested water sampling Audit field sampling and testing under property-owner requested water sampling
Oil and Gas: Injection Well Review Initial phase of review is to confirm that there are no immediate health risks or risks to groundwater sources DOGGR identifies disposal wells of concern Water Board locates water supply wells within 1 mile of disposal well Focusing initially on: Disposal wells < 1,500 feet deep (water supply depths)Disposal wells < 1,500 feet deep (water supply depths) Disposal into aquifers with < 3,000 mg/L TDSDisposal into aquifers with < 3,000 mg/L TDS Disposal wells with associated water supply wells with screens within 500 vertical feetDisposal wells with associated water supply wells with screens within 500 vertical feet Region 5 has issued 13267 Orders to 10 well operators Water samples collected from nine water supply wells near disposal wells (arsenic, nitrate and thallium above MCL, maximum TDS 1,800 mg/L).
