"SPCC"refers to spill prevention, control, and countermeasures.
"Steam flooding"is a thermal oil and gas recovery method in which steam is injected into a reservoir through injection wells and driven toward production wells. The steam reduces the viscosity of crude oil, causing it to flow more freely. The heat vaporizes lighter hydrocarbons; as they move ahead of the steam, they cool and condense into liquids that dissolve and displace crude oil. The steam provides additional gas drive. This method is also used to recover viscous oils. The technique is also called continuous steam injection or steam drive. Consistent with Section
3157(b) of Division 3 of the California Public Resources Code, steam flooding is not considered to be a well stimulation treatment.

93000, lists substances defined as toxic air contaminants.
"USEPA"refers to the United States Environmental Protection Agency.
"Waterflooding"is a method of secondary recovery in which water is injected into the reservoir formation to displace residual oil. The water from injection wells physically sweeps the displaced oil to adjacent production wells. Consistent with Section
3157(b) of Division 3 of the California Public Resources Code, waterflooding is not considered to be a well stimulation treatment.
"Well"is defined in the DOGGR Statutes and Regulations and means any oil or gas well or well for the discovery of oil or gas; any well on lands producing or reasonably presumed to contain oil or gas; any well drilled for the purpose of injecting fluids or gas for stimulating oil or gas recovery, repressuring or pressure maintenance of oil or gas reservoirs, or disposing of waste fluids from an oil or gas field; any well used to inject or withdraw gas from an underground storage facility; or any well drilled within or adjacent to an oil or gas pool for the purpose of obtaining water to be used in production stimulation or repressuring operations.
"Well stimulation treatment"is defined in the DOGGR Statutes and Regulations and means a treatment of a well designed to enhance oil and gas production or recovery by increasing the permeability of the formation. Well stimulation is a short term and noncontinual process for the purposes of opening and stimulating channels for the flow of hydrocarbons. Examples of well stimulation treatments include hydraulic fracturing, acid fracturing and acid matrix stimulation. Except for operations that meet the definition of "underground injection project" under California Code of Regulations, Title 14, Section
1761(a)(2), a treatment at pressures exceeding the formation fracture gradient shall be presumed to be a well stimulation treatment unless it is demonstrated to DOGGR's satisfaction that the treatment, as designed, does not enhance oil and gas production or recovery by increasing the permeability of the formation. Except for operations that meet the definition of "underground injection project" under California Code of Regulations, Title 14, Section
1761(a)(2), a treatment that involves emplacing acid in a well and that uses a volume of fluid equal to or greater than the acid volume threshold for the operation shall be presumed to be a well stimulation treatment unless it is demonstrated to DOGGR's satisfaction that the treatment, as designed, does not enhance oil and gas production or recovery by increasing the permeability of the formation. Well stimulation treatment does not include steaming, waterflooding or cyclic steaming and does not include routine well cleanout work; routine well maintenance; routine treatment for the purpose of removal of formation damage due to drilling; bottom hole pressure surveys; routine activities that do not affect the integrity of the well or the formation; the removal of scale or precipitate from the perforations, casing, or tubing; a gravel pack treatment that does not exceed the formation fracture gradient; or a treatment that involves emplacing acid in a well and that uses a volume of fluid that is less than the acid volume threshold for the operation and is below the formation fracture gradient.
"Workover"is the process of major maintenance or remedial treatments on an oil or gas well without changing the physical design of the well. Workovers include all operations that do not involve the initial drilling or reworking of wells and is regulated by DOGGR but without requirements for notices of intent or permits.
