Treatment Systems & Advanced BMPs
Treatment Systems & Advanced BMPs
Engineered solutions that actively remove pollutants from stormwater. These are the primary tools for facilities exceeding permit thresholds or managing heavy pollutant loads.
Key Advanced BMPs include:
Treatment Control Units – Advanced filtration, oil-water separators, and chemical treatment systems.
Containment & Discharge Reduction – Retention ponds, detention basins, and storage tanks to slow, store, or divert runoff.
Exposure Minimization – Roofs, shelters, and enclosures to prevent materials from contacting stormwater.
Advanced BMPs are mandatory for Level 2 ERA sites and are recommended for facilities with repeated exceedances or heavy industrial activity. They are the most effective way to reduce pollutants and maintain compliance.
Intermediate BMPs
Intermediate BMPs
Supplemental measures that provide extra protection, catching pollutants that Minimum BMPs may miss. Ideal for moderate-risk sites or proactive compliance programs.
Common Intermediate BMPs:
Filtration Devices – Drain inlet filters, media socks, and industrial wattles to trap sediment, absorb oil, and reduce metals.
Surface Cleaning – Street sweeping, industrial vacuuming, and power washing to remove accumulated pollutants before runoff events.
Intermediate BMPs often act as pretreatment, preparing runoff for engineered Treatment Systems.
Minimum Required BMPs
Minimum Required BMPs
Baseline, foundational practices required at all permitted sites. These reduce pollutant sources at the site and support overall stormwater management.
Key Minimum BMPs:
Good Housekeeping – Sweeping, vacuuming, and site organization to reduce pollutant buildup.
Preventive Maintenance – Inspections and timely repair of vehicles, equipment, and infrastructure to prevent leaks.
Spill & Leak Prevention/Response – Spill kits, containment systems, and emergency procedures.
Material Handling & Waste Management – Proper storage, covered containers, and secure disposal.
Erosion & Sediment Control – Stabilizing exposed soil and managing runoff to prevent sediment pollution.
Minimum BMPs are highly effective for baseline compliance but often need pretreatment and engineered treatment for sites with heavy pollutant loads.
