Storm Water Management Plan(SWMP) and MS4

On April 30, 2003, the University of Louisiana at Lafayette was declared a co-permittee to discharge storm water under a general permit issued to the Lafayette Consolidated Government (“LCG”) by Louisiana Department of Environmental Quality (“DEQ”). As a co-permittee, UL Lafayette is designated as a Municipal Separate Storm Sewer System (“MS4”). The University of Louisiana at Lafayette is a Co-permittee with LCG. As a Co-permittee, the MS4 is relying on another government entity to satisfy some permit obligations. Other Co-Permittees is the Lafayette regional airport and the cities/towns of Scott, Youngsville, Carencro, Duson, and Lafayette. Areas of UL Lafayette are located in Lafayette, St. Martin, Acadia, and Iberia Parishes. However, only University property within Lafayette Parish is included in the urbanized areas identified as a MS4 by DEQ. ​

The Office of Sustainability managages the University's SWMP and MS4 Permit. A good rule of thumb to remember is "only rain down the drain". If you have any questions or have any violations to report please contact Blair Begnaud

What is a MS4- Municipal Separate Storm Sewer System?

What is a Storm Water Management Plan ( SWMP )?

A SWMP is a plan that addresses the long-term effect of development on storm water quantity or quality and satisfies the requirement for post- construction water quality maintenance in an EPA or LDEQ storm water discharge general permit.

Grass clippings and leaves blown or swept into storm drains or into the street harms waterways and our river and is not allowed. Anything that is not rainwater is not allowed in the storm drains, coulees, ditches, or waterways. This is regulated by multiple laws and violators could be fined. Applicable laws and ordinances is 1972's Clean Water Act 33 U.S.C. §1251 et seq., 2006 Louisiana Law - RS 30:2531, and LCG's Stormwater Ordinance. For more resources about our local watershed and best practices please visit LCG's Water Quality Information Website.

Keep in mind that gitter is litter. Non-biodegradable confetti and glitter is not allowed on campus. Small litter like confetti and glitter is hard to pick up and will often make its way into local stom water systems and waterways. When litter gets into the local stormwater system it leads to the Vermilion Bayou in Lafayette which then leads to the Gulf of Mexico. We must protect our waterways from litter and other pollunants. 

Litter in waters can prevent beneficial uses, lead to flooding issues, degrade habitats and harm wildlife, and may endanger people's health. If you see someone intentionally littering into campus drains, coulees, or in Cypress Lake please contact Blair Begnaud.
