South Carolina Code of Regulations › Chapter 63 - DEPARTMENT OF HIGHWAYS AND PUBLIC TRANSPORTATION › Article 4 - ENGINEERING › Subarticle 6 - EROSION CONTROL › Section 63-380 - Standard Plan for Erosion, Sediment and Stormwater Runoff Control

Current through Register Vol. 48, No. 6, June 28, 2024
(1) All land
				disturbing activities under the jurisdiction of the Department must be
				performed in a manner that erosion is controlled and sediment is retained on
				the site concerned to the maximum extent feasible and stormwater is managed in
				a manner such that neither any significant on-site nor off-site damage and/or
				problem is caused or increased.
(2)
				All construction plans prepared by or for the Department must include designs
				to manage stormwater runoff and control erosion and sedimentation using
				state-of-the-art practices.
(3)
				Prior to the start of construction the contractor must submit in writing to the
				Engineer, for approval, his schedule for the accomplishment of temporary and
				permanent erosion and sediment control and stormwater management for the work
				to be performed.
(4) During
				construction, work must be scheduled and conducted in such a manner as to
				minimize soil erosion and control runoff, with particular attention to prevent
				contamination and depositing of sediment in adjacent streams, watercourses,
				lakes ponds and other water impoundments or onto adjacent properties, and to
				prevent on-site and off-site damage from stormwater runoff. Temporary and
				permanent measures to control erosion and sedimentation and manage stormwater
				runoff must be carried out in conjunction with clearing, grubbing and other
				earthwork operations and throughout the life of the project. Temporary measures
				such as berms, dikes, slope drains, terraces, earth rolls, sedimentation basins
				and temporary seeding must be provided until permanent drainage facilities and
				erosion control features are completed and operative. Permanent devices or
				measures such as culvert pipes, terraces gutters, bituminous curbs, permanent
				slope drains, riprap and permanent vegetation must be used and must be
				incorporated as soon as feasible.
(5) The Engineer's representative must
				periodically inspect work performed under the plan to insure that the necessary
				measures are implemented and are adequate for the needs of the site and
				affected off-site areas. The Department must require that additional measures
				be implemented in the event that the measures included in the plan are not
				sufficient to adequately control erosion and sedimentation and manage
				stormwater runoff.
(6) After a
				project has been completed and accepted in its entirety, the Department's
				Maintenance Forces must maintain the areas with top priority being to take the
				necessary steps to insure the continuance of proper erosion and sediment
				control and stormwater management measures as may be needed to prevent on-site
				and off-site damages or contamination of watercourse or impoundments.
(7) Each Resident Maintenance Engineer must
				prepare an inventory of existing erosion, sedimentation and stormwater problem
				areas. This list must be kept current and updated as conditions change. The
				Resident Maintenance Engineer, in conjunction with the District Office
				Personnel, must set priorities on the inventory and make the necessary
				corrections as time and funds permit.
(8) Maintenance must be performed in a manner
				that erosion is controlled and sediment is retained on the site to the maximum
				extent feasible and stormwater is managed in a manner such that neither any
				on-site nor off-site damage and/or problem is caused or increased. Existing
				vegetation must be retained and protected during maintenance to the maximum
				extent feasible.
