Oil Field Wastewater Reclamation Project Overview
Explore the details of an oil field produced wastewater reclamation project in Kern County. This project aims to reuse approximately 8.4 million gallons per day of wastewater for irrigation without requiring blending. The facility information includes treatment capacity, injection wells, and reservoirs for water storage. Learn about the project's location, facility specifics, proposed orders, and response to comments presented at the Central Valley Water Board meeting in April 2019.

Detectable results below drinking water standards Agenda Item 14 Slide 9 Central Valley Water Board Meeting 4/5 April 2019
PROPOSED ORDER Discharge Prohibitions: Prohibits specific discharges: Wastes to surface waters or drainages; Hazardous materials; Well stimulation treatment fluids; Produced wastewater from stimulated wells; and Untreated or partially treated waste. Agenda Item 14 Slide 10 Central Valley Water Board Meeting 4/5 April 2019
PROPOSED ORDER Effluent Limitations: Daily Maximum: Flow (8.4 mgd); and Oil & Grease (35 mg/l). Annual Average: Electrical Conductivity (1,000 umhos/cm); Boron (1.0 mg/l); and Chloride (200 mg/l). Agenda Item 14 Slide 11 Central Valley Water Board Meeting 4/5 April 2019
PROPOSED ORDER Discharge Specifications: Identifies specific regulatory requirements: Objectionable odors; Adequate seasonal capacity; and Reservoirs free of oil. Agenda Item 14 Slide 12 Central Valley Water Board Meeting 4/5 April 2019
PROPOSED ORDER Groundwater Limitations: Shall not exceed: Boron (0.75 mg/l); or Title 22 constituents (MCLs for drinking). Shall not contain: Taste or odor producing constituents; Toxic substances; or Concentrations that affect beneficial uses. Agenda Item 14 Slide 13 Central Valley Water Board Meeting 4/5 April 2019
PROPOSED ORDER Provisions: Identifies specific conditions: Sign Food Safety Project MOU; Engage in the Food Safety Project; and Submit a construction quality assurance report. Agenda Item 14 Slide 14 Central Valley Water Board Meeting 4/5 April 2019
PROPOSED ORDER Monitoring and Reporting Requirements: Produced Wastewater; Irrigation Water; Chemicals and Additives; and Groundwater. Agenda Item 14 Slide 15 Central Valley Water Board Meeting 4/5 April 2019
COMMENTS RECEIVED Supporting the Proposed Order: E & B Natural Resources Management Corp. and Sherwood Hills, LLC; and 29 individual letters. Opposing the Proposed Order: Center for Biological Diversity (CBD); Clean Water Action et al.; and Two letters opposing the practice. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 16
PUBLIC COMMENTS Comments regarding compliance with the California Environmental Quality Act (CEQA): The Water Board should be the Lead Agency; Kern County s Programmatic EIR does not address the reuse of unblended produced wastewater for irrigation; and The Water Board should prepare a new site-specific EIR; and Not in compliance with CEQA. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 17
PUBLIC COMMENTS RESPONSE: Circumstances to change the Lead Agency have not been satisfied. Kern County s Programmatic EIR covers blended and unblended produced wastewater for irrigation. Proposed Project satisfies mitigation measures identified in the Programmatic EIR. Staff finds that proposed Order complies with CEQA. Modified CEQA findings in the proposed Order. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 18
PUBLIC COMMENTS Degradation of groundwater is expected to occur as a result of the proposed project. Constituents in produced wastewater are a potential concern to the environment and human health. RESPONSE: Discharger s Antidegradation Analysis complies with the State Antidegradation Policy. Produced wastewater analyzed for Oil Field Chemical List. Detected concentrations are below drinking water standards. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 19
PUBLIC COMMENTS Best practicable treatment or control (BPTC) measures are not supported by an independent analysis or consideration by the Board. BPTC measures do not consider the removal of constituents in produced wastewater. RESPONSE: BPTC is discharge specific. Proposed Order includes adequate BPTC for the proposed project. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 20
PUBLIC COMMENTS Runoff to surface water or the structural failure of Sherwood s Reservoirs are not considered. Proposed WDRs need to include design and construction standards for the dams. RESPONSE: The discharge of wastes, including runoff, to surface waters is prohibited. Proposed WDRs require a construction quality assurance report prepared by a registered professional. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 21
PUBLIC COMMENTS The Discharger is not required to participate in Food Safety efforts. The Food Safety Expert Panel has not prepared a report that states the use of blended produced wastewater can be extrapolated to the use of unblended produced wastewater. RESPONSE: Proposed Order was modified to require participation. Analytical results for both produced wastewater and blended produced wastewater are under review. Scientific review underway to determine potential constituents and concentrations that may pose a threat. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 22
PUBLIC COMMENTS South Coast Air Quality Monitoring District study found a significant overlap of chemicals between stimulation activities and routine activities. Produced wastewater from stimulated wells and non- stimulated wells should be prohibited. RESPONSE: Detectable results for the Oil Field Chemical List are below drinking water standards. Water quality results are submitted to Food Safety Expert Panel for review. The Panel has not determined either poses a threat to crop safety or human health. Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 23
LATE REVISIONS Edited the proposed WDRs and Information Sheet Added Reservoir No. 4 to Construction Quality Assurance Report requirement. Added a new Discharger: Yurosek Farms, LLC Agenda Item 14 Central Valley Water Board Meeting of 4/5 April 2019 Slide 24
