Full Breakdown
C. C. C. " Section 21-48 makes it unlawful to connect any pipe or channel that discharges anything other than approved stormwater into receiving waters, to operate an illicit connection, or to discharge any matter besides authorized storm or surface water into the city's MS4 or waters of the state; using a high-PAH pavement product anywhere in the city is likewise banned. Accidental or unavoidable discharges must be reported to the stormwater division within 24 hours, with immediate containment and cleanup. Section 21-46 requires every property owner along a watercourse to keep it free of trash, debris, and obstructions that would pollute or slow the flow, and requires water quality buffers along jurisdictional waters and wetlands where vegetation is a "no disturb zone" absent an approved restoration plan.
Spill responders must notify the Columbia Fire Department and the stormwater hotline, confirm in writing within five business days, and keep spill records for at least five years (§ 21-47).
Violations & Fines
Violating the stormwater article draws a civil penalty of up to $1,000.00 per violation under § 21-54, with each day counted as a separate offense; unpaid penalties can be pursued in circuit court after 30 days. Section 21-59 adds criminal exposure: anyone who negligently, willfully or intentionally violates the article, or knowingly falsifies a required report or permit document, is guilty of a misdemeanor, with each day a new offense. The city may also seek injunctions or reimbursement for its own corrective action.
