Development Permits- Stormwater Requirements

Who Regulates Stormwater Pollution? 

The Municipal Regional NPDES Stormwater Permit (also known as the MRP) requires that the City of Dublin place conditions on development projects to incorporate site design measures, source controls, treatment measures, and, on larger projects, flow duration controls (FDCs).
