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!

 Rain Check?


You Can Make a Difference

Some things we all can do as part of a Rain Check include:

  • Make sure all litter stays inside our cars when traveling (including cigarette butts) and dispose of trash in the proper place.
  • Pick up pet waste in public spaces such as parks and rest areas, as well as in our own yards, and dispose of it in a trashcan.
  • Check cars for oil, brake fluid, or antifreeze leaks, and get leaks fixed right away.
  • Wash cars on grass or gravel instead of the street or driveway, or go to a car wash that recycles water.
  • Recycle used motor oil and car batteries at designated centers.
  • Check the amount of pesticides and fertilizers used on lawns to be sure that we don’t use too much; excess will run off.

 MS4 Permit Program


Georgia DOT was issued a Municipal Separate Storm Sewer Systems (MS4) Permit in January 2012 by the Georgia Environmental Protection Division (EPD). 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 Georgia Environmental Protection Division as "MS4 Permitted Areas." To see if you are within an MS4 Permitted Area, click on the storm drain photo to the right to see a map showing all counties within the MS4 program highlighted in yellow.

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.  View our press release on the MS4 program accomplishments thus far.


 Permit Control Measures


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.

Georgia DOT has been working to detect and reduce the pollution that enters our natural waters. In accordance with the MS4 permit, our stormwater management program focuses on the following measures in an effort to reduce stormwater pollution:

  1. Public Education
  2. Public Involvement
  3. Illicit Discharge Detection and Elimination
  4. Construction Site Stormwater Runoff Control
  5. Post-Construction Stormwater Management
  6. Pollution Prevention for Municipal Type Operations

These measures were designed to educate and inform the public on stormwater pollution and the impact it has on our ecosystems, as well as to reduce runoff pollution from Georgia DOT properties and construction sites. Although Georgia DOT has always strived to be a good steward of Georgia’s environment and natural resources, we have stepped up our efforts to further enhance our stormwater management and water quality protection measures.

Georgia DOT is currently rewriting our entire Drainage Manual to incorporate new technologies for best management practices that are designed to reduce stormwater pollution. In addition, we are implementing new stormwater training courses for our employees and contractors, so that they are all informed of the most current and effective methods for reducing stormwater pollution. While Georgia DOT 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. The video, brochure and other resources on this page will tell you more about the actions we are taking to prevent stormwater pollution and how you can support this effort.




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:
