Berkeley County, SC Environmental Rules: Stormwater Management (2026)

C. Code Reg. " Section 65-985 lists roughly twenty specific powers the ordinance grants the county to meet that mandate, including authority to prohibit illicit connections, require construction and post-construction control measures on new development and redevelopment, inspect sites, and pursue pollutant-load reductions in impaired waterbodies. Under section 65-986, the article applies only to "those portions of unincorporated Berkeley County defined as the 'regulated area'" plus any incorporated areas that opt in with county council approval, and the Berkeley County Engineer or a designee handles day-to-day administration and SWMP consistency review.

Division 4, section 65-1031, makes it "unlawful for any person to connect any pipe, open channel, or any other conveyance system that discharges anything except stormwater" into the county's system or waters of the state, with narrow carve-outs for things like uncontaminated groundwater infiltration and firefighting flows. Section 65-1042 lets the county engineer enter and inspect regulated property at reasonable times with notice, or immediately without notice where a discharge threatens health or the environment. Enforcement under section 65-1051 runs through a written Notice of Violation before the county suspends work, revokes approvals, withholds a certificate of occupancy, or refers a case to the county attorney for injunctive relief.
