Stormwater Regulations

For construction activities disturbing one or more acres of total land, or will disturb less than one acre of land in unincorporated jurisdictions but are part of a larger common plan of development or sale that will ultimately disturb one or more acres, a Storm Water Pollution Prevention Plan (SWPPP) will need to be developed.

 Greene County Stormwater Regulations

The NPDES Phase II rule requires construction sites disturbing equal to or greater than one acre and less than five acres to control pollutants in stormwater runoff. Construction activity disturbing less than one acre requires a permit if it is part of a larger common plan of development or sale disturbing a total of one acre or greater, or is individually designated for permit coverage by the NPDES permitting authority.

SWP3 Inspection Requirements

Once approval of the SWP3 has been granted, construction may commence subject to other required zoning, building, or other applicable permit approvals.  A minimum of five (5) days prior to commencing clearing or demolition work, the Greene County Engineer's Office shall be contacted at (937) 562-7500 to insure proper sediment and erosion control practices are in place before work begins.  

Sites will be inspected by the Greene County Engineer's Office at a minimum on a monthly basis until the site has been permanently seeded and stabilized.
