Construction Site Storm Water Runoff Control
Storm drainThe construction process creates a significant amount of silt and sediment in a short period of time. The goal of this minimum control is to reduce pollutants in any storm water runoff. This requirement is applicable for construction activities that result in a land disturbance of greater than or equal to one acre. Also included in the requirements is any construction activity disturbing less than one acre if the construction activity is part of a larger common plan of development of sale that would disturb one acre or more.

Construction Permit (CGP)

Notice of Intent

According to the Ohio EPA Permit No. OHC000003, “Operators that discharge storm water associated with construction activity must submit an NOI application form in accordance with the requirements of Part II of this permit to obtain authorization to discharge under this general permit.” The Notice of Intent (NOI) can be found on the Ohio EPA Division of Surface Water’s website Program Forms and Permits.

Storm Water Pollution Prevention Plan

A Storm Water Pollution Prevention Plan (SWP3) shall be developed for each site covered by the storm water general permit. The SWP3 shall fulfill the requirements of the Ohio EPA Permit.

Construction Site Inspection

The Ohio EPA Permit No. OHC000003 states, “At a minimum, procedures in an SWP3 shall provide that all controls on the site are inspected at least once every seven calendar days and within 24 hours after any storm greater than one-half inch of rain per 24 hour period.” The Construction Site Inspection Checklist can be utilized to assure that all Best Management Practices all working properly.

Erosion and Sediment Control for Small Lot Construction

Per Ohio EPA, “For residential or commercial developments with sublots, NPDES permit coverage must be continued on every lot until the lot achieves final stabilization as defined in Part VII of the CGP. For developments with a centralized control (i.e., sediment settling ponds or inlet protection), which receives drainage from multiple lots, the developer may be required to maintain the centralized control until all of the homes are built with the land temporarily stabilized.”
The Ohio EPA requires, “If a developer opts to transfer permit responsibility to the new lot owner or operator building the structure (homebuilder) once the lot is sold, the new lot owner must submit an Individual Lot Notice of Intent application at least 7 days prior to initiating construction activities. The developer must allow the new lot owner access to the developer’s SWP3. The new owner must then maintain and/or install any lot specific sediment controls and develop a site map indicating the location of the BMPs. Once the Individual Lot NOI is processed, the new lot owner is responsible for complying with the CGP on his or her lot."
The City of Oregon issued requirements for erosion and sediment control for small lot construction sites on January 30, 2004.

Design Resources

“Ohio EPA recommends that the erosion, sediment, and storm water management practices used to satisfy the conditions of this permit (CGP), should meet the standards and specifications in the current edition of Ohio’s Rainwater and Land Development manual.
The City of Oregon also uses the Storm Water Management Standards Manual, Second Edition, September 2006, by the Maumee River Regional Storm Water Coalition and the Maumee River RAP Urban Runoff Action Group, as a guide in storm water design.
