Part A - GENERAL PROVISIONS
Section 61-9.503.A.9 - General definitions

(a) "Apply sewage sludge or sewage sludge applied to the land" means land application of sewage sludge.

(b) "Base flood" is a flood that has a one percent chance of occurring in any given year (i.e., a flood with a magnitude equalled once in 100 years).

(c) "Class I sludge management facility" is any publicly owned treatment works (POTW), as defined in 40 CFR 501.2, required to have an approved pretreatment program under R.61-9.403.8(a)(a)(including any POTW located in a State that has elected to assume local program responsibilities pursuant to R.61-9.403.10(e)(e)) and any treatment works treating domestic sewage, as defined in R.61-9.122.2, classified as a Class I sludge management facility by the EPA Regional Administrator, or, in the case of approved State programs, the Regional Administrator in conjunction with the Department, because of the potential for its sewage sludge use or disposal practice to affect public health and the environment adversely.

(d) "Cover crop" is a small grain crop, such as oats, wheat, or barley; grasses; or other crop grown for agronomic use.

(e) "CWA" see R.61-9.122.2(b)(b)Definitions.

(f) "Domestic septage" is either liquid or solid material removed from a septic tank, cesspool, portable toilet, Type III marine sanitation device, or similar treatment works that receives only domestic sewage. Domestic septage does not include liquid or solid material removed from a septic tank, cesspool, or similar treatment works that receives either commercial wastewater or industrial wastewater and does not include grease removed from a grease trap at a restaurant.

(g) "Domestic sewage" is waste and wastewater from humans, or household operations that is discharged to or otherwise enters a treatment works.

(h) "Dry weight basis" means calculated on the basis of having been dried at 105 degrees Celsius until reaching a constant mass (i.e., essentially 100 percent solids content).

(i) "EPA" means the United States Environmental Protection Agency.

(j) "Feed crops" are crops produced primarily for consumption by animals.

(k) "Fiber crops" are crops such as flax and cotton.

(l) "Food crops" are crops consumed by humans. These include, but are not limited to, fruits, vegetables, and tobacco.

(m) "Ground water" is water below the land surface in the saturated zone.

(n) "Industrial wastewater" is wastewater generated in a commercial or industrial process. See R.61-9.504 for additional definitions.

(o) "Municipality" see R.61-9.122.2(b)Definitions. The definition includes under section503 of this regulation a special district created under State law, such as a water district, sewer district, sanitary district, utility district, drainage district, or similar entity, or an integrated waste management facility as defined in section201(e)(e) of the CWA, as amended, that has as one of its principal responsibilities the treatment, transport, use, or disposal of sewage sludge.

(p) "Permitting authority" means the Department.

(q) "Person" see definition in R.61-9.122.2(b)Definitions.

(r) "Person who prepares sewage sludge" is either the person who generates sewage sludge during the treatment of domestic sewage in a treatment works or the person who derives a material from sewage sludge.

(s) "Place sewage sludge or sewage sludge placed" means disposal of sewage sludge on a surface disposal site.

(t) "Pollutant" is an organic substance, an inorganic substance, a combination of organic and inorganic substances, or a pathogenic organism that, after discharge and upon exposure, ingestion, inhalation, or assimilation into an organism either directly from the environment or indirectly by ingestion through the food chain, could, on the basis of information available to the Department, cause death, disease, behavioral abnormalities, cancer, genetic mutations, physiological malfunctions (including malfunction in reproduction), or physical deformations in either organisms or offspring of the organisms.

(u) "Pollutant limit" is a numerical value that describes the amount of a pollutant allowed per unit amount of sewage sludge (e. g., milligrams per kilogram of total solids); the amount of a pollutant that can be applied to a unit area of land (e. g., kilograms per hectare); or the volume of a material that can be applied to a unit area of land (e.g., gallons per acre).

(v) "Runoff" is rainwater, leachate, or other liquid that drains overland on any part of a land surface and runs off of the land surface.

(w) "Sewage sludge" is solid, semi-solid, or liquid residue generated during the treatment of municipal wastewater or domestic sewage in a treatment works. Sewage sludge includes, but is not limited to, domestic septage; scum or solids removed in primary, secondary, or advanced wastewater treatment processes; and a material derived from sewage sludge. Sewage sludge does not include ash generated during the firing of sewage sludge in a sewage sludge incinerator or grit and screenings generated during preliminary treatment of domestic or industrial sewage in a treatment works. See R.61-9.504 for Industrial sludge definition.

(x) "State" means the State of South Carolina.

(y) "Store or storage of sewage sludge" is the placement of sewage sludge on land on which the sewage sludge remains for two years or less. This does not include the placement of sewage sludge on land for treatment.

(z) "Treat or treatment of sewage sludge" is the preparation of sewage sludge for final use or disposal. This includes, but is not limited to, thickening, stabilization, and dewatering of sewage sludge. This does not include storage of sewage sludge.

(aa) "Treatment works" is either a Federally owned, publicly owned, or privately owned device or system used to treat (including recycle and reclaim) either domestic sewage or a combination of domestic sewage and industrial waste of a liquid nature.

(bb) "Wetlands" see R.61-9.122.2(b)Definitions.

(cc) [Reserved]

(dd) "Person who applies sewage sludge" may be the generator, preparer, or a land applier.
