"Best management practices" (BMPs) means
schedules of activities, prohibitions of practices, maintenance procedures, and other management practices to
prevent or reduce the pollution of waters of the State. BMPs also include treatment requirements, operating
procedures and practices to control plant site runoff, spillage or leaks, sludge or waste disposal, or drainage from
raw material storage.
"Down-gradient" means the portion of the water
table that is down the hydraulic slope of the water table with respect to a specific area or point of reference.
"Evaporation basin" means a basin designed specifically
for the atmospheric or enhanced evaporation of liquid.
"Groundwater" means water below the land surface found
in fractured rock or various soil strata.
"Groundwaters of the State" means all
sources of groundwater wholly, partially, or bordering the State of South Carolina or within its jurisdiction.
"Hydraulic loading" means the rate at which liquid is
applied to the land per unit area. The term "application rate" may be used for "hydraulic loading".
"Hydrogeologic characteristics" means the physical
properties of the subsurface and its interaction with the hydraulic properties of groundwater (e.g., migration or
"Infiltration" means the flow of water downward from
the land surface into and through the soil.
"Land" for the purpose of this regulation means the soil and rock
above the water table aquifer and the ground surface.
"Land Application" means use and/or disposal of treated
wastewater, sewage sludge, industrial sludge, septage, or additional sources (see R.61-9.505.1(b)(2)) to the land.
"Land Application Permit" refers to a permit
issued by the Department applicable to a treatment system, source or site with no resulting discharge to surface
waters of the State.
"Land of the State" means all land surface which is
wholly or partially within the State of South Carolina or within its jurisdiction.
"Land slope" means the rate of increase or decrease of
elevation over a given linear distance.
"Land surface" means the area of land open to the
"New or expansions" means a facility or land application site
that is: new and has not been permitted (including existing sites such as golf courses that have not been used for
effluent disposal); an increase (either in quantity or loading) in pollutant disposal to the facility or land
application site; a change in the pollutant disposal to the facility or land application site (such as the
introduction of a new pollutant in the effluent); or expansions (in physical size, or hydraulic loading) of existing
permitted facilities or land application sites. The term "new or expanding" may also be used.
"Monitoring well" means any well used to sample
groundwater for water quality analysis or to measure groundwater levels.
"Percolation pond" means any lagoon, basin or
constructed impoundment having a leakage rate in excess of 500 gallons/day/acre.
"Permeability" means the capacity of soil, rock, or
other material to transmit fluids.
- Means filter backwash, sewage, sewage sludge, industrial sludge, septage, or industrial, municipal, agricultural
and domestic waste.
- Does not mean water, gas, or other material which is injected into a well to facilitate production of oil or
gas, or water derived in association with oil and gas production and disposed of in a well, if the well used
either to facilitate production or for disposal purposes is approved by authority of the State in which the well
is located, and if the State determines that the injection or disposal will not result in the degradation of
groundwater or surface water resources.
"Potable water well" means a well that supplies
drinking water for human consumption.
"Restrictive soil horizon" means the top of
the most impermeable soil layer encountered.
"Seasonal high water table" means the highest water
table as determined in the soil profile by the encountered indications of soil mottling or iron concretions or by
measuring seasonal fluctuations of the water table in a water table well over a period acceptable to the Department.
"Septage" means the liquid and solid material pumped from
septic tank, cesspool or similar domestic sewage treatment system, or a holding tank when the system is cleaned or
"Spray field" means a specified area where properly
treated wastes, treated effluent from process, agricultural or domestic wastewater, sewage sludge, industrial sludge
or other sources is applied to the land. The terms "application area", "application site", or "spray disposal area"
may also be used.
"Soil boring" means any hand- or mechanically-powered
method by which samples of the subsurface can be retrieved for characterization or description.
"Source" means any discernible conveyance, including but not
limited to, any pipe, ditch, channel, tunnel, conduit, well, discrete fissure, container, rolling stock, or mobile
equipment (such as sludge application truck or device), from which pollutants are or may be discharged. This term
does not include return flows from irrigated agriculture.
"State permit" refers to a permit issued by the Department for
other sources covered by this regulation (other than Land Application Permits) such as activities covered under
R.61-9.505.1(b)(2). The term "State Permit Program" may also be used to describe the entire permit program under
"Storage or holding basin" means any
basin designed to retain wastewater before, during or after treatment and would not include waters of the State.
"Tile field" means a specific area where a network of soil adsorption
trenches is installed below the land surface for the purpose of providing final treatment and disposal of
"Treated wastewater" means properly treated effluent from
process or domestic wastewater, treated wastes from other sources (see R.61-9.505.1(b)(2)) or treated effluent from
a treatment facility.
"Up-gradient" means the portion of the water table that
is up the hydraulic slope of the water table with respect to a specific area or point of reference.
"Vadose zone" means the zone between the land surface and the
"WWTP" means wastewater treatment plant.
"Water table" means the level below the land surface at
which all the voids are filled with water at a pressure equal to atmospheric. The depth to the water level in the
ground is to be measured at least 24 hours after encountering it in a well.
"Water table mound" means a high point in
the seasonal or normal water table which is artificially created by the infiltration of liquid.
"Well" means any excavation which is cored, bored, drilled, jetted,
dug, or otherwise constructed and has a depth greater than its largest surface diameter.
"ND" or "No Discharge"
means land application. The terms "ND permit" or "No Discharge permit" may be used for "Land Application permit".
