Regulations & Guidance:

Please follow the latest version of the Rainwater and Land Development Manual for erosion and sediment control design guidance.
OEPA has recently released a Sediment Basin Compliance Spreadsheet. This spreadsheet, programmed in excel, allows engineers to enter design data and receive output information important to SWPPP review. Filling out and submitting this spreadsheet to Warren Co SWCD with SWPPP documents will speed up review and ensure compliance with requirements of the CGP.

Stormwater Pollution Prevention Plans (SWP3):
The SWP3 contents are described in Part III of the NPDES Construction General Permit (CGP). Although the SWP3 does not need to be submitted to Ohio EPA to obtain coverage under the CGP through the NOI application, it must be retained at the construction site at all times during the construction activity. However, Warren SWCD does require submittal and approval of the SWP3 as part of the EDP requirements.
An SWP3 must address all minimum components of the CGP and conform to the specifications of Ohio Department of Natural Resources' Rainwater and Land Development Manual. This manual describes Ohio’s standards for storm water management, land development, and urban stream protection.
