The Storm Sewer System and the Construction Community

The City of Lorain is a permittee under the Ohio EPA's Municipal Separate Storm Sewer System (MS4) program.  While there are many responsibilities under this program, one requirement of the program focuses on the management and regulation of construction activity within the City. In accordance with Clean Water Act requirements, Lorain Codified Ordinance Chapter 1529: CONSTRUCTION SITE SOIL EROSION, SEDIMENT, AND OTHER WASTES AND STORM WATER RUNOFF REGULATIONS  has been adopted by the Lorain City Council and describes the requirements for storm water management for construction project occurring within Lorain. All construction activity within the City with less than one (1) acre in size of disturbed area and not part of a larger plan of development shall be required to maintain compliance with Minimum Standards for Small Construction Sites. In addition to compliance with City Ordinance, all construction sites disturbing one or more acres of land must obtain an Ohio EPA issued Construction Notice of Intent.

Post Construction Inspection Requirements

The Federal Clean Water Act, state standards, and local ordinances require Storm Water Best Management Practices (BMPs), such as detention ponds, be installed and maintained in order to control the quality and quantity of water being discharged to receiving waters. As outlined in the City of Lorain Codified Ordinance 1531.09, BMPs within the City of Lorain require annual certified inspections with written reports due to the City Engineer's Office by May 1st of each year. Please be aware that these standards require BMP owners to properly maintain, repair and, if necessary, reconstruct BMPs and provide a schedule for the maintenance frequency for the facility.
