MS4 Permit

Licking County & Others MS4 Permit

The Licking County Commissioners hold a small Municipal Separate Storm Sewer System (MS4) permit under the National Pollutant Discharge Elimination System (NPDES) which sets limits on what can be discharged, monitoring and reporting requirements, and other provisions to ensure that the discharge does not affect water quality or people's health.  Licking Soil & Water manages and assists with various aspects of the MS4 Program for many communities in Licking County including: City of Newark, City of Heath, City of Pataskala, Village of Buckeye Lake, Village of Granville, Village of Hebron, Village of Hanover, Etna Township, Licking Township, Granville Township, Harrison Township, Madison Township, Newton Township and Union Township.

The permit outlines 6 Minimum Control Measures or MCMs that entities are responsible for making progress and meeting goals for each category.
