MCM 4 Construction Site Stormwater Control
Contents
Introduction
Controlling sediment and other pollutants from construction sites is crucial to an effective stormwater management program. Minimum Control Measure (MCM) 4 of the MS4 General Permit requires permittees to have and enforce a construction site stormwater runoff control program to reduce the impacts of land disturbing activities to stormwater.
MS4 General Permit requirements for MCM 4
The construction site stormwater runoff control program must include:
- A regulatory mechanism that establishes erosion, sediment, and waste controls as stringent as the Construction Stormwater permit requirements for construction sites.
- A site plan review procedure for conducting site plan reviews to ensure compliance with the construction stormwater runoff control regulatory mechanism.
- Written procedures for the receipt and consideration of reports of noncomplaince at construction sites received from the public.
- Construction site inspection procedures for inspecting public and private construction sites. The procedures should include: procedures for identifying and prioritizing sites for inspections, the frequency of site inspections, the name or title of the person responsible for inspections, and a checklist or other written means to document site inspections.
- Enforcement response procedures to compel compliance with the construction stormwater runoff control regulatory mechanism.
- Documentation as described here.
