Municipal Separate Stormwater Sewer System (MS4) Program
Under the LPDES General Permit for Discharges from Regulated sMS4s, the Lafayette Airport Commission (LAC) is required to develop a comprehensive Stormwater Management Program for the entire LAC property. To find out more on the work the Lafayette Airport Commission is doing for its Public Education and Outreach, Public Involvement/Participation, Illicit Discharge Detection and Elimination, Construction Site Stormwater Runoff Control, Post-Construction Stormwater Management in New Development and Redevelopment and Pollution Prevention/Good Housekeeping for Municipal Operators Programs click on the links below.

An illicit discharge is any discharge to a storm drain that is not composed entirely of stormwater unless covered by a LDEQ discharge permit. Examples of illicit discharges include rinsing paint brushes into a storm drain, contractor directly pumping soil laden water into a storm drain, and spilled material entering the storm drainage system such as fuels or oils. Illicit discharges contribute high levels of pollutants, including heavy metals, oil and grease, solvents, viruses, and bacteria to receiving water bodies. Pollutant levels from these discharges have been shown to be high enough to significantly degrade receiving water quality and threaten aquatic, wildlife, and human health.
If you observe an illicit discharge on LAC property, report this occurrence to LAC by completing the Compliant Section of the Incident reporting form below and emailing it to LAC at the email address found under the contact information section.
Post Construction Stormwater refers to the difference in rainwater runoff from an area before and after development. As wilderness areas such as swamps, prairies, and forests are developed into cities, streets and residential areas the amount of water and pollutants that runoff during a rain event into the nearest waterway increases substantially. The increase in runoff leads to flooding, loss of fish, erosion and property loss. Along with the increased runoff come increases in pollutants which enter the waterways. Some of the most common are trash, fertilizers, oils and pesticides. These pollutants can cause increased algae growth and introduce toxic substances into the water and food chain that can impact your ability to fish, swim and enjoy our waterways.
Around the country cities are enacting a variety of requirements in an attempt to lessen the impacts that development causes on waterways. The most common and most cost effective ways that this is managed is by bring nature back to developed areas by incorporating trees, native plants, wetland area and ponds into designs. These additions slow the flow of rainwater from a site giving the water more time to flow into the soil to replenish groundwater. They can also remove pollutants from the water by filtering or giving pollutants chance to settle out prior to the water flowing into a waterway.
