Summary

Columbia County bans discharging anything but clean stormwater into its MS4 storm-drain system under Code of Ordinances § 34-148, and requires an approved stormwater management plan before any development involving five acres or more of land disturbance under § 34-150(b). Violators face a written notice, a possible stop-work order, and civil penalties of up to $2,500 per day under § 34-162.

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

It is unlawful for any person to throw, drain, run or otherwise discharge to any component of the MS4, or to cause, permit or suffer to be thrown, drained, run or allow to seep, or otherwise discharge into such system, any matter of any nature excepting only such stormwater or surface water as authorized in this division. ... The requirement for a stormwater concept plan applies to activities involving five acres or more of land, unless exempted in section 34-151.

Full Breakdown

Article IV, Division 2 of the county code regulates discharges into the county's municipal separate storm sewer system, or MS4. ' The director of engineering and environmental services can exempt specific low-risk flows, such as water-line flushing, unpolluted groundwater, air-conditioning condensation and firefighting discharges, if they aren't a significant pollution source under § 34-148(b). Section 34-149 separately bans illicit connections, any pipe or channel tied into the MS4 that carries something other than approved stormwater, and requires violators to pay for redirecting the connection to the sanitary sewer.

Development activity itself is regulated under § 34-150: any project disturbing five acres or more needs an approved stormwater concept plan before the county will issue a land-disturbance permit, and subdivisions are treated as a single land-disturbing activity rather than lot-by-lot. Plans go to the director of engineering and environmental services for review under § 34-153, with a permit fee set by the county's schedule of fees and charges, and approved plans expire after one year unless renewed. The director can suspend or revoke a development permit under § 34-154 for violating plan conditions, failing to follow a stop-work order, or creating an immediate downstream danger.

Violations & Fines

A violation under § 34-162 starts with written notice from the director of engineering and environmental services describing the violation and the time allowed to correct it. Violations are treated as an infraction subject to the same penalty structure as the county's erosion ordinance in § 34-72, meaning civil penalties up to $2,500.00 per day, plus possible business-license revocation for anyone who begins work without a required stormwater management plan.

Frequently Asked Questions

What can I legally send into a Columbia County storm drain?
Only stormwater or surface water is allowed under § 34-148(a). The director can permit specific low-risk exceptions such as water-line flushing, unpolluted groundwater, air-conditioning condensate, lawn watering and firefighting discharges if they aren't a significant pollution source, but anything else, from wash water to construction waste, is a prohibited discharge into the MS4.
Does every construction project need a stormwater plan?
Only projects disturbing five acres or more automatically need a stormwater concept plan under § 34-150(b); smaller projects still need an approved stormwater management plan under § 34-153(a) unless specifically exempted in § 34-151, which covers minor home landscaping, agricultural best-management practices and owner-occupied single-family construction more than 200 feet from state waters.
What if I accidentally connect a pipe to the storm system?
That's an illicit connection under § 34-149(a), and it must be disconnected and redirected to the sanitary sewer at the violator's expense under § 34-161. The engineering and environmental services division enforces this alongside the water and sewer division director, who must approve any correction.
What penalty applies for a stormwater violation?
Section 34-162(b) applies the same penalty scale as the county's erosion ordinance, § 34-72, so civil penalties can reach $2,500.00 per day of violation. The county can also require restoration of the land to its undisturbed condition and can revoke a violator's business license or work permit under § 34-162(d).
