Summary

Every stormwater permit application in unincorporated Horry County must include a sediment and erosion control plan built to the state's construction general permit standard. Code § 17.7-47(f) requires the plan before ground is disturbed, and § 17.7-46 bans discharges like concrete washout and fuel spills from any construction site.

These county ordinances apply to unincorporated areas of Horry County. Incorporated cities within the county may have their own rules that take precedence over county-level regulations.

(f)Sediment and erosion control plan. A sediment and erosion control plan consistent with the most recent version of SCDHEC's construction general permit (CGP) must be submitted with all stormwater permit applications. All erosion/sediment control practices details, vegetative stabilization details and standard notes shall be included. The Horry County Stormwater Design Manual includes specific requirements for inclusion in the sediment and erosion control plan.

Full Breakdown

Horry County folds its erosion-control rules into the same stormwater ordinance rather than a stand-alone chapter. 7-47(f) requires that "a sediment and erosion control plan consistent with the most recent version of SCDHEC's construction general permit (CGP) must be submitted with all stormwater permit applications," including "all erosion/sediment control practices details, vegetative stabilization details and standard notes," and the county's own Stormwater Design Manual adds specific content requirements on top of the state template. " The same section separately bans specific construction-site discharges outright: washout water from concrete, stucco, paint, curing compounds and other construction materials; fuels, oils and other vehicle-maintenance pollutants; and soaps or solvents used to wash equipment, unless the washout is captured by an approved control such as a sediment basin.

7-76(j) puts the burden of routine inspection on the owner, who must run on-site erosion-control inspections under the CGP with a certified inspector and keep those reports available to the county on request. 7-88.

Violations & Fines

Failing to follow an approved sediment and erosion control plan draws a written notice of violation from the stormwater department describing the deficiency and the correction deadline under § 17.7-51; missing that deadline brings a stop-work order within seven days. The underlying violation of Article III is punished under the general penalty, § 1-8, up to a $500 fine or 30 days in jail, separate from any state CGP enforcement by SCDHEC.

Frequently Asked Questions

Do I need a separate erosion-control permit in Horry County?
No, it's part of the same stormwater permit package. Section 17.7-47(f) requires a sediment and erosion control plan consistent with SCDHEC's construction general permit to be submitted along with the master plan, grading and drainage plan, and SWPPP for the same project.
Can I wash out a concrete truck on a Horry County job site?
Not directly onto the ground or into the drainage system. Section 17.7-46 lists "wastewater from washout of concrete" among the discharges prohibited from a construction site unless it's captured by an approved control, such as a sediment basin, before it can reach the stormwater system.
What extra erosion-control paperwork applies to a long pipeline or road project?
Linear projects over 1,000 feet trigger a heavier requirement under § 17.7-46(9): a detailed erosion and sediment control plan plus a stormwater pollution prevention plan (SWPPP), on top of the standard package required for smaller sites.
Who inspects erosion controls once construction starts?
The property owner does. Section 17.7-76(j) makes the owner responsible for running on-site erosion-control inspections under SCDHEC's construction general permit, using a certified inspector, and for keeping those inspection reports on hand for the county to review on request.
