|Construction Site Storm Water Runoff Control|
The 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.
The design of Construction Site storm water controls shall be in accordance with the Ohio EPA’s Construction General Permit #OHC000004, the City of Oregon’s Storm Water Management Plan, and Codified Ordinances of Oregon, Ohio Section 1177.06 Storm Sewers.
Construction Permit (CGP)
Construction site storm water runoff is regulated by the OHIO ENVIRONMENTAL PROTECTION AGENCY AUTHORIZATION FOR STORM WATER DISCHARGES ASSOCIATED WITH CONSTRUCTION ACTIVITY UNDER THE NATIONAL DISCHARGE ELIMINATION SYSTEM (Ohio EPA Permit No.: OHC000004). This permit came into effect on April 11, 2013 under the Ohio EPA's Constuction Storm Water Program.
Notice of Intent
According to the Ohio EPA Permit No. OHC000004, “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. OHC000004 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 City of Oregon issued requirements for erosion and sediment control for small lot construction sites on January 30, 2004.
“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.
