Current through Register Vol. 46, No. 3, March 25, 2022
As used in these regulations, the following terms shall have the meanings as indicated below:
1. "Commission" means the South Carolina Land Resources Conservation Commission.
2. "Department" means the South Carolina Department of Highways and Public Transportation.
3. "Easement" means a grant or reservation by the owner of land for the use of such land by others for a specific purpose or purposes, and which must be included in the conveyance of land affected by such easement.
4. "Erosion" means the wearing away of land surface by the action of wind, water, gravity, ice, or any combination of those forces.
5. "Erosion and Sediment Control" means the control of solid material, both mineral and organic, during a land disturbing activity to prevent its transport out of the disturbed area by means of air, water, gravity, or ice.
6. "Exemption" means those land disturbing activities that are not subject to the sediment and stormwater requirements contained in these regulations.
7. "Infiltration" means the passage or movement of water through the soil profile.
8. "Land Disturbing Activity" means any use of the land by any person that results in a change in the natural cover or topography that may cause erosion and contribute to sediment and alter the quality and quantity of stormwater runoff.
9. "Nonerodible" means a material, e.g., riprap, concrete, plastic, etc., that will not experience surface wear due to natural forces.
10. "Person" means any State or federal agency, individual, partnership, firm, association, joint venture, public or private corporation, trust, estate, commission, board, public or private institution, utility, cooperative, municipality or other political subdivision of this State, any interstate body or any other legal entity.
11. "Sediment" means solid particulate matter, both mineral and organic, that has been or is being transported by water, air, ice, or gravity from its site of origin.
12. "Stabilization" means the prevention of soil erosion by surface runoff or wind through the establishment of a soil cover through the implementation of vegetative or structural measures.
"Stormwater Management" means, for:
(a) quantitative control, a system of vegetative or structural measures, or both, that control the increased volume and rate of stormwater runoff caused by manmade changes to the land;
(b) qualitative control, a system of vegetative, structural, or other measures that reduce or eliminate pollutants that might otherwise be carried by stormwater runoff.
14. "Stormwater Management and Sediment Control Plan" means a set of drawings, other documents, and supporting calculations prepared to apply to land disturbing activity, which contains all of the information and specifications to support the design.
15. "Stormwater Runoff" means direct response of a watershed to precipitation and includes the surface and subsurface runoff that enters a ditch, stream, storm sewer or other concentrated flow during and following the precipitation.
16. "Variance" means the modification of the minimum sediment and stormwater management requirements for specific circumstances where strict adherence of the requirements would result in unnecessary hardship and not fulfill the intent of these regulations.
17. "Waiver" means the relinquishment from sediment and stormwater management requirements by the appropriate plan approval authority for a specific highway construction project on a case-by-case review basis.
18. "Water Quality" means those characteristics of stormwater runoff from a land disturbing activity that relate to the chemical, biological, or radiological integrity of water.
19. "Water Quantity" means those characteristics of stormwater runoff that relate to the rate and volume of the stormwater runoff to downstream areas resulting from land disturbing activities.
20. "Watershed" means the total or partial drainage area contributing stormwater runoff to a single point.
