Discharger. Any person who discharges, or causes or permits to be discharged, any wastewater.

Domestic discharger. Any person who discharges, or causes or permits to be discharged, any domestic waste.

Domestic waste.

FSOs that share a common grease control device shall be considered to be individual establishments and shall be required to obtain individual discharge permits. An establishment classified as an FSO must comply with all applicable regulations regardless of whether or not it owns, rents, or leases the property or premises on which food preparation occurs. The designation of an establishment as a significant industrial user as defined in section 27-143 supersedes the classification of food service operation.

Grease control device. A device for separating and retaining waterborne fats, oil or grease prior to the wastewater exiting the device and entering the sanitary sewerage system. These devices also serve to collect settleable solids generated by and from food preparation activities. Grease control devices include equipment such as grease traps, grease interceptors, grease removal devices used with interceptors or other equipment approved by the director of the department of inspection and code enforcement, or his duly authorized representative, the sole purpose of which is to retain, remove, or destroy fats, oil or grease and settleable solids prior to discharge to the sanitary sewerage system.

Grease removal device (GRD). A plumbing appliance which is installed in the sanitary sewerage system in order to intercept free floating fats, oils, and grease from wastewater discharges. Such equipment has the ability to remove the entire range of commonly available free-floating fats, oils, and grease automatically without intervention from the user except for maintenance. The removed material is essentially water-free which allows recycling of the removed product.

Grease trap. A large capacity gravity separator, which is designed and installed so as to provide for the separation and retention of fats, oil or grease and which is generally installed below grade outdoors with provisions for above grade accessibility for cleaning purposes.

Hotels, motels, schools, office buildings, apartment houses, and other establishments that discharge only domestic wastes are not considered to be industries.

Instantaneous limit. The maximum concentration of a pollutant allowed to be discharged at any time, determined from the analysis of any discrete or composited sample collected, independent of the industrial flow rate and the duration of the sampling event.

Interference. A discharge which, alone or in conjunction with a discharge or dischargers from other sources, both: (a) Inhibits or disrupts the POTW, its treatment processes or operations or its sludge processes, use, or disposal; and (b) Therefore is a cause of a violation of a requirement of the POTW's LPDES permit (including an increase in the magnitude or duration of a violation) or of the prevention of sewage sludge use or disposal in compliance with the following statutory provisions and regulations or permits issued thereunder (or more stringent state or local regulations): Section 405 of the Clean Water Act, the Solid Waste Disposal Act (SWDA) (including Title II, more commonly referred to as the Resource Conservation and Recovery Act (RCRA) and including state regulations contained in any state sludge management plan prepared pursuant to Subtitle D of the SWDA), the Clean Air Act, the Toxic Substances Control Act, and the Marine Protection, Research and Sanctuaries Act.

New source. Any building, structure, facility or installation from which there is or may be a discharge of pollutants, the construction of which commenced after the publication of proposed pretreatment standards under section 307(c) of the Act which will be applicable to such source if such Standards are thereafter promulgated in accordance with that section, provided that: (i) The building, structure, facility or installation is constructed at a site at which no other source is located; or (ii) The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or (iii) The production of wastewater generating processes of the building, structure, facility or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant, and the extent to which the new facility is engaged in the same general type of activity as the existing source should be considered.

Parish. The Parish of Jefferson, State of Louisiana.

Pass through. Discharge which exits the POTW into waters of the United States in quantities or concentrations which, alone or in conjunction with a discharge or discharges from other sources, is a cause of a violation of any requirement of the POTW's LPDES permit (including an increase in the magnitude or duration of a violation).

Upon finding that an industrial user meeting the criteria of a significant industrial user as defined above, has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the director may at any time, on his own initiative or in response to a petition received from an industrial user or POTW, and in accordance with 40 CFR 403.8(f)(6), determine that such industrial user is not a significant industrial user.
