To develop within certain jurisdictions located in Warren County, the site owner is required to obtain an Earth Disturbing Permit (EDP) on any project where the proposed disturbed area is greater than one acre. The jurisdictions where our MS4 services are provided, and therefore EDPs issued by Warren Co SWCD, can be found on the Earth Disturbing portion of our website.

To complete an application, site owners will need a Stormwater Pollution Prevention Plan (SWP3) prepared along with construction drawings, basin calculations (if applicable), basin operation and maintenance documents, and a completed Earth Disturbing Permit application. A SWP3 template along with the sediment basin compliance tool used for design calculations can be found on the Ohio EPA website. Once the SWP3 has been developed, site owners can apply for a Notice of Intent (NOI) through the Ohio EPA. The NOI permit number is needed on the EDP application. Construction drawings and other related details must also be approved by the engineer overseeing post-construction for a permit to be issued.

All documents can be submitted electronically on our website. Once a full application submission has been received, a member of Warren Co SWCD’s Urban Team will send an email receipt and add it to the review queue. After the disturbed acreage has been verified an invoice will be emailed to the point of contact. Warren SWCD will send either an approval or request for additional information within two weeks of receiving the submittal.

If you have additional questions on preparing the required documents or the application process, please contact out office at (513) 695-1337. We look forward to helping you with your next project!

​Winter is quickly approaching in Warren County, and the snowfall that occurs during winter months can result in excessive amounts of soil erosion and transport of sediment into our local waterways. For your construction site to be compliant with Ohio EPA Construction General Permit regulations, workers should begin applying temporary stabilization measures for areas that will be left idle over winter months. For a disturbed site, stabilization techniques are required if areas are to remain dormant for more than 14 days.
 
Preparing the disturbed area for winter conditions by providing cover over bare soil and ensuring proper function of controls will result in minimal environmental impact. For all disturbed sites it is essential to install perimeter and inlet protection so that snowmelt leaving the site passes through a filter prior to discharging into the drainage network. Additionally, it is necessary to install rock check dams and construction entrances prior to the onset of weather to avoid loss of sediment downslope. Other stabilization measure providing cover over a large portion of the site include seeding, mulching, and sodding. The goal is to apply these vegetative treatments by November, but sometimes this is not always practical with varying schedules.
 
To learn more about coverage options, specifications, and seeding schedules, browse through Chapter 7 of the Ohio Rainwater and Land Development Manual. Warren Co SWCD’s expert Urban Team is also available to help – call us at 513-695-2901.
