(Added by O-3803)

ARTICLE 1 - GENERAL

410.1.010 DEFINITIONS.

For the purposes of this Chapter the following words and phrases shall have the meanings respectively ascribed to them by this Chapter. Words and phrases not ascribed a meaning by this Chapter shall have the meanings ascribed by the regulations implementing the National Pollutant Discharge Elimination System, Clean Water Act Section 402, 33 U.S.C. 1342(p), including, but not limited to, 40 C.F.R. 122.2 and 40 C.F.R. 122.26(b), and Division 7 of the California Water Code, as they may be amended from time to time, if defined therein, and if not, to the definitions in an applicable permit issued by the California Regional Water Quality Control Board - Los Angeles, as such permits may be amended from time to time.

"Authorized discharge" means any discharge that is authorized pursuant to an NPDES Permit or meets the conditions set forth in this Chapter.

"Automotive service facility" means a facility that is categorized as such in any one (1) of the Standard Industrial Classification (SIC) or North American Industry Classification System (NAICS) Codes. For inspection purposes, permittees need not inspect facilities with SIC Code 5013, 5014, 5541, or 5511; provided, that these facilities have no outside activities or materials that may be exposed to stormwater.

"Best management practices" or "BMPs" means methods, measures, schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to prevent or reduce pollutants in discharges to the MS4 and thence into waters of the United States. BMPs include treatment requirements, operating procedures and practices to control runoff, spillage or leaks, sludge or waste disposal and drainage from raw material storage; public education and outreach; proper planning of development projects; structural and nonstructural controls; and operations and maintenance procedures which can be applied before, during and after pollution-producing activities, including, but not limited to, proper clean-out of catch basins and proper waste handling and disposal. See 40 C.F.R. 122.2.

"Commercial development" means any development on private land that is not heavy industrial or residential. The category includes, but is not limited to: hospitals, laboratories and other medical facilities, educational institutions, recreational facilities, plant nurseries, car wash facilities, mini-malls and other business complexes, shopping malls, hotels, office buildings, public warehouses and other light industrial complexes.

"Commercial malls" means any development on private land comprised of one (1) or more buildings forming a complex of stores which sells various merchandise, with interconnecting walkways enabling visitors to easily walk from store to store, along with parking area(s). A commercial mall includes, but is not limited to: mini-malls, strip malls, other retail complexes, and enclosed shopping malls or shopping centers.

"Conditionally exempt essential nonstormwater discharges" are certain categories of discharges that are not composed entirely of stormwater and that are allowed by the Regional Water Board to discharge to the MS4, if in compliance with all specified requirements; are not otherwise regulated by an individual or general NPDES Permit; and are essential public services that are directly or indirectly required by other State or Federal statute and/or regulation. These include nonstormwater discharges from drinking water supplier distribution system releases and nonemergency fire fighting activities. Conditionally exempt essential nonstormwater discharges may contain minimal amounts of pollutants; however, when in compliance with industry standard BMPs and control measures, do not result in significant environmental effects. (See 55 Fed. Reg. 47990, 47995 (Nov. 16, 1990).)

"Construction activity" includes any construction or demolition activity, clearing, grading, grubbing, or excavation or any other activity that results in land disturbance. Construction does not include emergency construction activities required to immediately protect public health and safety or routine maintenance activities required to maintain the integrity of structures by performing minor repair and restoration work, maintain the original line and grade, hydraulic capacity, or original purposes of the facility. See "routine maintenance" definition for further explanation. Where clearing, grading or excavating of underlying soil takes place during a repaving operation, State General Construction Permit coverage is required if more than one (1) acre is disturbed or the activities are part of a larger plan.

"Discharge" means any release, spill, leak, pump, flow, escape, dumping or disposal of any pollutant, from any point source, into the environment, including waters of the United States, and City’s MS4.

"Hazardous materials" means any materials, wastes or mixture of wastes defined as a "hazardous substance" or "hazardous waste" pursuant to Section 311(b)(2) of the Clean Water Act, 33 U.S.C. 1321(b)(2), or the Resource Conservation and Recovery Act ("RCRA"), 42 U.S.C. 6901 et seq., the Comprehensive Environmental Response, Compensation and Liability Act ("CERCLA"), 42 U.S.C. 9601 et seq., or the Carpenter-Presley-Tanner Hazardous Substance Account Act, ("HSAA"), California Health and Safety Code Sections 25300, et seq., and all future amendments to any of them, or as defined by the State Water Resources Control Board or the California Regional Water Quality Control Board - Los Angeles. Where there is a conflict in the definitions employed by two (2) or more agencies having jurisdiction over hazardous waste or water pollution, the terms "hazardous materials" and "hazardous waste" shall be construed to have the broader, more encompassing definition.

"Illicit connection" means any device or artifice, excluding roof drains and other similar connections, connected to the municipal separate storm sewer system, without a permit, through or by which an illicit discharge may be discharged. Examples include channels, pipelines, pipes, conduits, inlets and outlets connected directly to the municipal separate storm sewer system.

"Industrial/commercial facility" means any facility involved used for the production, manufacture, storage, transportation, distribution, exchange or sale of goods or commodities, and any facility used in providing professional and nonprofessional services. This category of facilities includes, but is not limited to, any facility defined by the Standard Industrial Classifications (SIC) or North American Industry Classification System (NAICS).
