Regulations & Guidance:
|
City of Mason Stormwater Regulations and Erosion & Sediment Control Regulations exist in the Zoning Ordinance
The City of Mason Zoning Ordinance is put in place to uphold the Ohio EPA NPDES Construction General Permit. All requirements of the CGP apply in addition to the City of Mason Zoning Ordinance.
|
Ohio’s Standards for Stormwater Management, Land Development and Urban Stream Protection. Please follow this manual for all technical guidance and specifications for sediment and erosion control measures.
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.

OEPA NOI:
The NOI process is now completely online through the EPA website utilizing a program called STREAMS. Follow the link below to apply for and NOI.
City of Mason Earth Disturbing Permit Application:
The City of Mason EDP Application can be submitted at any point in the process, however, a pre-construction meeting can not be scheduled until this form has been submitted. The purpose of this form is to capture important contact information so that eventually our inspectors know who to contact for erosion and sediment control needs during construction. Please wait to fill this form out and submit when all contacts are known.
Operation and Maintenance Document Guidance:
Operation and Maintenance documents typically entail the O&M Agreement and the O&M Plan. In Ohio, responsibility for operation and maintenance of all post construction stormwater control measures (SCM) lies with the owner of the SCM. Typically, the property owner on which the SCM is constructed is the owner of the control measure and is legally obligated to operate and maintain the control measure. In some cases, a separate entity, such as a homeowners association, might take responsibility for a SCM. Legal obligations for operation, maintenance, inspection and repair of SCMs will be identified in the O&M documents. O&M Agreements are typically executed between the property owner and a local government jurisdiction (i.e. municipal or county department). An O&M Agreement and Plan are legally binding documents that lists the SCMs and their legally defined locations, ownership, operation and maintenance requirements. Inspection frequency, funding requirements and access easements to the SCMs are also a necessary part of all O&M Plans.
Warren County Recorder's Office has specific requirements for all documents to be recorded. If these guidelines are not followed, a $20 fee will ensue.
