Construction water permitting state comparison

Each state manages construction water permitting differently. EPA authorizes many states to administer the National Pollutant Discharge Elimination System (NPDES) stormwater permitting program. Most construction companies will need to obtain NPDES permit coverage through their state. Construction companies in states covered by the federal NPDES program and in areas in Indian Country will obtain permitting coverage through EPA's Multi-Sector General Permit. Use the chart below to determine if additional requirements apply to your operations.
