“General Permit” means a State permit or National Pollutant Discharge Elimination System (NPDES) permit issued under Regulation 61-9.122.28 authorizing a category of discharges or activities under the Pollution Control Act (PCA) and CWA within a geographical area.

“Gravity Sewer” means a pipeline carrying wastewater or treated effluent which flows exclusively under the influence of gravity (i.e., no pump station).

“Interceptor Sewer” means a pipeline system designed to transport wastewater or treated effluent from one location to another.  Interceptor sewers can flow under pressure (i.e., force main) or by gravity.

“Interceptor Tanks” means tanks and other devices designed to remove solids from raw wastewater prior to discharging to an alternative collection system.

“L.F.” means linear feet.

“Land Application Permit” means a permit issued by the Department to a discharger for all land application disposal systems.

“Main Sewer” means the sanitary sewer system beginning at the point where two (2) or more individual service lines connect together, except as otherwise defined as a service connection and except as noted in R.61-67.300.A.4.

“Major Sources of Waste” means those wastes that may have or tend to have a potentially adverse effect on wastewater treatment facility design and operation and water quality (e.g., textile dyeing, finishing, metal plating, and slaughter house waste).  This includes waste identified as a “Significant Industrial User” under Regulation 61-9.403.2(n).

“mg/l” means milligrams per liter.

“MGD” means million gallons per day.

“NPDES” means National Pollutant Discharge Elimination System.

“NPDES Permit” means a permit issued by the Department to a discharger pursuant to regulations adopted by the Department’s Board for all point source discharges into surface waters, and shall constitute a final determination of the Board.

“Navigable Waters” as defined in Regulation 19-450, Permits for Construction in Navigable Waters.  Navigability is determined by the Department.

“Notice of Intent (NOI)” means a form used by potential permittees to notify the Department, within a specified time that they intend to comply with the general permit, or that they do not desire to be covered by the general permit and desire an individual construction permit.

“OSHA” means the Occupational Safety and Health Administration.

“Permitted Flow” means the value equivalent to the sum of flows as computed for the purpose of issuing construction permits for sewer lines or other connections to the systems.

“PCA” means the South Carolina Pollution Control Act, S.C. Code Ann. Section 48-1-10 et seq. (1987), and any subsequent amendments.

“Pretreatment Facility” means a facility which provides reduction of the amount of pollutants, elimination of pollutants or the alteration of the nature of pollutant properties in wastewater prior to or in lieu of discharging or otherwise introducing such pollutants into a publicly owned treatment works (POTW) or other treatment system not owned by the facility. 

“Primary Source Water Protection Area” means the surface-water flow system and drainage area upstream of an existing or proposed public water system intake, delineated by the Department as the in-stream twenty four (24) hour time of travel distance for the ten (10) percent exceedance flow (i.e., primary source water protection area).

“Private Entity” means any private corporation, association, partnership, corporation, industry, copartnership, firm, trust, estate, any other legal entity whatsoever, or an agent or employee thereof.

“Public Entity” means organizations such as a city, town, county, municipality, or special purpose sewer district.

“Pump and Haul” means an operation whereby process wastewater as defined in Regulation 61-9.122.2 or domestic wastewater is collected and stored in Department approved facilities and then hauled by tanker truck or other vehicle to an off-site receiving facility such as a POTW.  Pump and haul in this context does not apply to management of spills.

“Receiving Waters” means waters of the State.

“Service Connection” means an individual gravity sewer line, or an individual pump station and force main, serving only one (1) building or one (1) residential lot with domestic or industrial wastewater connecting to a gravity sewer system.  Oil/Water Separators, pH Adjustment Systems, and other similar simple industrial wastewater treatment systems (as determined by the Department) will be considered a component of the service connection when a local pretreatment permit is not required.  A Service Connection does not include the following:

  • Individual connections, where at the time of connection, design flow contribution shall be greater than five (5) percent of the existing wastewater treatment facility’s design capacity or shall generate flows greater than fifty thousand (50,000) gallons per day.
  • Individual connections to force main sewers and vacuum sewer connections beginning with the valve pit.
  • A gravity sewer line or pump station and force main serving more than one (1) building or more than one (1) residential lot.
  • Sewer lines that have the reasonable ability to serve any additional projects and/or buildings in the future.

“Sewers” means a gravity sewer line, vacuum sewers or a force main.

“State” means the State of South Carolina.
