#D003Category 'C'Any discharger for which waste discharge requirements have been prescribed pursuant to Section 13263 of the Water Code not included in Category A or Category B as described above. Included are dischargers having no waste treatment systems or that must comply with best management practices, dischargers having passive treatment and disposal systems, or dischargers having waste storage systems with land disposal.high
#D004AdsorptionThe attraction and adhesion of a layer of ions from an aqueous solution to the solid mineral surfaces with which it is in contact.high
#D005ApplicantThe entity, whether a person, private company, or public agency, that applies for coverage under this Order. Upon issuance of a Notice of Applicability by the Executive Officer of the applicable Regional Water Board, the Applicant becomes the 'Permittee'.high
#D006AquiferRock or sediment in a formation, group of formations, or part of a formation which is saturated and sufficiently permeable to transmit economic quantities of water to wells and springs.high
#D007Aquifer Storage and Recovery (ASR)Aquifer storage and recovery involves the storage of water in a suitable aquifer through a well during times when water is available, and recovery of the water when it is needed.high
#D008Aquifer Storage ZoneDefined by the horizontal and vertical extent of injected water. The aquifer storage zone will generally extend farther away from the injection well(s) depending upon stratigraphic variations in hydraulic conductivity, groundwater gradient, flow direction, and operation of extraction well(s).high
#D009Area of Hydrologic InfluenceThe area of hydrologic influence is defined as the area of the aquifer which is affected chemically or physically by the ASR project (the aquifer storage zone plus any additional areas affected by the ASR project).high
