Regulations
Jefferson County SWPPP Checklist: Concrete Washout
Jefferson County
Jurisdiction: Jefferson County (Unincorporated areas and overlapping MS4 jurisdictions)
Permit / authority: Governing Authority: Jefferson County Stormwater Management
Jefferson County is highly protective of its water quality and storm sewer systems, which discharge directly into state waters. The county actively enforces illicit discharge rules and strict Right-of-Way (ROW) policies. If you are managing concrete washout in JeffCo, your setup must meet these exact criteria.
1. Liquid Waste Containment & Illicit Discharges
The Rule: Liquid waste, explicitly including concrete washout, must be contained and disposed of properly at all times. The JeffCo Nuance: Jefferson County classifies any activity that results in an unauthorized substance entering the storm sewer system or waterways as an illicit discharge. The county is responsible for what flows through its storm sewers, even if the pollutants originate on private property, which means private site containment is heavily scrutinized.
2. Strict Right-of-Way (ROW) Container Rules
The Rule: Washout or debris containers temporarily placed within the public Right-of-Way (ROW) require a Use and Construction Permit and are subject to official inspection. Placement Restrictions: Containers must be placed to fit entirely within a parking lane. They must be kept a minimum of 20 feet from any corner, alley, or entrance, and they are generally not permitted on arterial roads. The JeffCo Nuance: County policy explicitly dictates that containers must not leak, overflow, or be filled in a manner that allows debris to fall into the roadway or blow away. The permit holder is held entirely financially responsible for all cleanup expenses if pollutants discharge into waterways or the storm sewer, alongside any damage to the curb, gutter, or sidewalk.
3. Mandatory Container Visibility in the ROW
The Rule: Any container placed in the ROW must be highly visible to traffic and the public. The JeffCo Nuance: All containers must have a minimum 6-inch wide by 4-foot long strip of reflective tape placed vertically on each corner. Alternatively, traffic cones must be placed around the container in accordance with the Manual on Uniform Traffic Control Devices (MUTCD).
4. Zero-Tolerance Public & Law Enforcement Reporting
The Rule: The storm sewer system includes both concrete and metal infrastructure, as well as roadside ditches that convey stormwater. Keeping high-pH washout out of these conveyances is mandatory. The JeffCo Nuance: Jefferson County actively encourages the public to report urgent illicit discharges directly to the Jefferson County Sheriff's Department. A leaking washout setup in JeffCo is not just an environmental permit issue; it can trigger a direct law enforcement response from the community.
