City of Bowling Green / Warren County
To fully comply with federally mandated stormwater regulations the City of Bowling Green, Kentucky is required to address runoff from post construction areas. Post construction stormwater management in areas undergoing new development or redevelopment is necessary because runoff from these areas has been shown to significantly affect receiving water bodies. Many studies indicate that prior planning and design for the minimization of pollutants in post construction stormwater discharges is the most cost effective approach to stormwater quality management. However, compliance with the City of Bowling Green’s stormwater ordinance is not an option. The City of Bowling Green is an NPDES Phase II regulated municipality and has coverage under the NPDES Phase II general stormwater permit, KYG20. To satisfy the requirements of the City’s NPDES Phase II permit, and as the operator of the MS4, the City of Bowling Green has the authority to inspect properties- including private, residential, and commercial properties- for noncompliance and can issue a notice of violation (NOV) for any deficiency or infraction onsite.

The O&M Plan for a site with privately maintained BMPs contains the following elements:
1. An Inspection and Maintenance Agreement signed by the developer or BMP owner. This agreement states that the owner is responsible for maintaining the BMP perpetually and performing inspections.
2. A BMP location map clearly indicating the locations of all stormwater BMPs, drainage easements, access easements, roadways, and stormwater system components as they relate to the stormwater BMPs.
3. Schematics for each BMP. The schematics should be detailed enough to allow for future inspections of the BMP(s) and stormwater system. If more than one BMP is on the project site, schematics of each BMP must be provided.
4. Inspection and maintenance templates for each type of BMP. For manufactured BMPs, the template must have maintenance items filled out in the template prior to submission to the City.
