Carson Municipal Code § 9531.5 Water Quality

The operator shall at all times conduct operations to avoid any adverse impacts to surface and groundwater quality, and shall comply with the following provisions.

(Ord. 16-1590, Exh. B (§ 1))

The operator shall comply with all provisions of a potable water management plan that has been approved by the Petroleum Administrator. The plan shall include best management practices, water conservation measures, and the use of a drip irrigation system. The water management plan shall be reviewed by the operator every three (3) years to determine if modifications to the plan are required. Any modifications to the water management plan shall be submitted to the Petroleum Administrator for review and approval. This Section does not apply to existing facilities.

(Ord. 16-1590, Exh. B (§ 1))

Construction Storm Water Pollution Prevention Plan ("SWPPP"). The operator shall maintain and implement all provisions of a storm water pollution prevention plan ("SWPPP") that has been submitted to the Regional Water Quality Control Board, if required. The operator shall provide the Petroleum Administrator with a copy of the SWPPP, and any future modifications, revisions, or alterations thereof, or replacements therefor upon written or verbal request of the Petroleum Administrator. The SWPPP shall be updated prior to new construction activities as required by the Regional Water Quality Control Board.

(Ord. 16-1590, Exh. B (§ 1))

A. Prior to any new development, the operator shall prepare and submit a baseline study of all groundwater resources located within and beneath the project site or directly adjacent to the site, to specifically include an analysis of the location and reservoir characteristics of all existing groundwater resources, a chemical analysis of the groundwater, and an overall assessment of the groundwater quality.

B. The operator shall not inject any water spoils/wastewater derived from the any oil or gas operations into any nonexempt or DOGGR exempt freshwater aquifers.

C. Within thirty (30) days of request by the City, the operator shall deposit funds with the City necessary to retain a third party to prepare a hydrological analysis groundwater testing program prior to any construction activities, or alternately, provide comparable analyses performed through the groundwater ambient monitoring and assessment program or other reliable source as determined by the Petroleum Administrator. Depending on the results of the geohydrological analyses the Petroleum Administrator has the discretion to require the operator to install one (1) or more groundwater monitoring wells to allow for confirmation that groundwater is not being affected by oil and gas activities. As part of the groundwater testing program the operator is required to provide the Petroleum Administrator with annual monitoring and testing results.

D. The operator shall be responsible for obtaining a field/site study from DOGGR. If DOGGR does not provide this to the operator then the operator shall submit evidence detailing DOGGR's response to their field/site study request to the Petroleum Administrator for review.

E. The operator shall provide to the Petroleum Administrator a copy of the DOGGR annual injection project review (if the operator is operating a water injection or water disposal well) upon written or verbal request by the Petroleum Administrator. The operator shall provide to the Petroleum Administrator the results of any DOGGR required cement casing integrity testing, including radial cement evaluation logs or equivalent upon written or verbal request by the Petroleum Administrator, before any wells are put into production.
