Stormwater Management Requirements
Fueling sites must control runoff to prevent pollutants from reaching natural water bodies
- Must install oil-water separators or treatment units in drainage systems
- Require engineered stormwater detention or retention basins
- EPA’s Spill Prevention, Control, and Countermeasure (SPCC) plans often apply
- Permits may be required under the Clean Water Act’s NPDES program
Site Drainage Design Standards
Proper drainage systems are mandatory to direct contaminated runoff away from fueling areas
- Sloped concrete pads are used to channel spills toward collection points
- Drains must be connected to approved treatment or containment systems
- Grading must ensure water flows away from tank inlets and dispensers
- Open discharge is typically prohibited unless pre-treated
Impermeable Surface Coverage Limits
Regulations may restrict how much land can be covered by non-porous materials like asphalt or concrete
- Local codes may limit coverage to control heat and runoff impact
- Fueling areas must be paved to ensure easy spill cleanup and containment
- Green buffer zones or permeable zones may be required for balance
- Some jurisdictions incentivize porous pavement outside fueling zones
Environmental Compliance and Reporting
Sites must demonstrate ongoing compliance with drainage and runoff control regulations
- Annual or semi-annual environmental inspections may be mandated
- Maintenance logs for separators, sumps, and filters must be kept
- Violations can lead to fines, enforcement orders, or shutdowns
- Construction plans must show drainage, grading, and containment details
