Stormwater Pollution Prevention


Rain Check​​​​​​

Keeping our Streams, Rivers and Lakes Healthy and Clean

What is a “Rain Check?” Did you know that our daily activities can have an impact on water quality, especially when it rains? This site provides information about stormwater pollution and tips on how we can work together to ensure the health of our natural waters. Check out our video, brochures, and other resources below for more information!

Post-Construction Stormwater for Design Professionals

Description: This two-day course will describe the new GDOT post construction stormwater design policy and provide designers with hands on design exercises on detailing the implementation of these requirements on projects in MS4 areas.  This training will include information on policy, design and documentation for all GDOT projects for each milestone submittal. 

The stormwater planning process will be discussed in detail from the pre-concept phase through final design.  The new post-construction stormwater BMPs that are included in the Manual and their design requirements will be covered, along with design examples for each BMP.  Participants should bring a calculator for use with in-class design examples.

MS4 Areas

MS4 Permitted Areas ​

Georgia DOT was issued a Municipal Separate Storm Sewer System (MS4) permit in January 2012 by the Georgia Environmental Protection Division (EPD). This permit will be re-issued every 5 years and the next permit is expected to be issued in January 2017. The MS4 permit provides guidelines for agencies to prevent excessive stormwater discharges, dumping, spills, erosion and pollutants from contaminating nearby waterways. The MS4 permit program regulates the discharge of stormwater from Georgia DOT roadways and properties designated by the EPD as “MS4 Permitted Areas.” Additional cities and counties have been designated as a MS4 Permitted Area since the issuance of GDOT’s 2012 MS4 permit. GDOT’s 2017 MS4 permit will include these additional MS4 Permitted Areas and a complete list will be made available after the permit is issued. In the interim, the list of these areas can be found in the draft permit on EPD’s website. To see if you are within an MS4 Permitted Area, click on the map above showing all counties within the MS4 program.

While the Department is already taking broad measures to prevent pollution from entering our streams, rivers and lakes, there is still much that we can do together to help keep our water clean. This page and the link below will tell you more about the actions we are taking to mitigate stormwater pollution. The MS4 permit activities are an integral part of Georgia DOT’s commitment to be a good environmental steward.

As people learn more about the effects of stormwater runoff and how it impacts the quality of our streams, rivers, and lakes, they can take positive actions to help reduce negative effects. Even simple changes can have far-reaching results that benefit Georgia residents, businesses, ecosystems, and wildlife.

Keep Georgia Peachy Clean!

Litter is becoming an increasing problem in our state and can negatively affect many areas of your life.


  • Litter can block stormwater drains resulting in flooding and costly repairs.
  • Litter negatively impacts real estate values, discouraging economic development.


  • Litter diminishes aesthetics of streets, roads and highways.
  • More than 25,000 accidents are caused by vehicle-related road debris each year in the U.S.
  • Water & Environment

  • It only takes 1 HOUR for chemicals to leach from cigarette butts when in contact with water.
  • Animals can get caught in plastic items and become injured or even strangled.
  • Litter-causing water pollution can impact recreation areas and drinking water supplies.

Every year, Georgia DOT spends over $10 million cleaning up litter. Georgia DOT has created programs and teamed with organizations to help reduce litter on our roadways in addition to their existing maintenance activities and contracts.

  • In 2015 there were 92 active Adopt-A-Highway groups covering over 100 miles. 1,269 participants volunteered 2,253 person hours collecting over 2,380 bags of roadside litter.
  • Every year in April each Georgia DOT District participates in the Great American Cleanup by reassigning crews to concentrate on litter pickup for a week.
  • The partnership with Sponsor-A-Highway Program began by providing litter pickup in metro Atlanta in November 2011. The program now has expanded to three of the Department’s Districts outside of Atlanta, in Hall, Gwinnett, and Cherokee Counties.

Here are a few things you can do to help keep our roadways and waterways free of litter:

  • Carry a litter bag in your car.
  • For smokers, keep a designated place in your car for cigarette butts and ashes until you’re ready to throw them away.
  • Secure your cargo before driving and don’t use truck beds as mobile garbage cans.
  • Properly cover trash receptacles outside to prevent litter escaping.
  • Be proactive! Walk to the nearest recycling or trash container.
  • Encourage friends & family to take pride in their community and not to litter.
  • Make a small change – pick up one piece of litter each day.
  • Only empty your RV holding tanks in authorized dump stations.
  • Participate in community clean-ups.

Keep Georgia Beautiful

Georgia DOT is committed to training its employees and contractors on good construction site practices and municipal operations that minimize impacts of stormwater runoff from Georgia DOT properties or rights-of-ways, including what to do in the event of a spill or other actions that may result in unintended impacts on our water bodies. We are also educating the general public on how everyone can help to minimize pollution due to stormwater runoff. Please check out the following resources:
