The Environmental Quality Division provides education to more than 550 businesses throughout Grand Prairie that deal with the repair, detail, salvaging and selling of cars. Through the Automotive Related Business Program's annual inspections at these facilities, the city ensures that these businesses are committed to being good stewards of the environment and good neighbors to the citizens of Grand Prairie.

As residents of Grand Prairie, you can also help protect our community from vehicle pollution by taking the following steps:

Properly dispose of used vehicle fluids.

1 quart of used motor oil can contaminate 1 million gallons of water if it was spilled into a storm drain or even in front of your house. That’s enough to supply drinking water to 50 households for one year!

Used vehicle fluids should not be poured down the sink or into the trash. Take fluids to an oil recycling center or to a Household Hazardous Waste Collection event for proper disposal.

Avoid washing your vehicle in your driveway.

Washing a car in your driveway with detergent adds excessive nutrients called phosphates to our streams and rivers that cause algae to bloom on top of the water. It causes a foul smell because plants underneath the water decay and die because not enough sunlight can penetrate to the bottom because the algae forms a "blanket" on top of the water. If you do wash your vehicle at home, follow these tips:

  • Look for environmentally friendly cleaning products that are phosphate free.
  • Use smaller amounts of water by using a spray nozzle.
  • Use your lawn (rather than your driveway) as the first step of the filtering system.

Washing Car in Yard

Avoid driving aggressively. 

By slowing down and avoiding aggressive driving, you can improve your fuel economy by 5% if driving in town, or by up to 33% on the highway.

Slowing down and keeping to the speed limit also helps to reduce air emissions. Typically for every 5 MPH you drive over 60 MPH, it’s like paying an additional $0.20 per gallon of gas you use. If you have a 13-gallon fuel tank, you can save $2.60 per tank just by driving the speed limit.

Maintain your vehicle.

  • Change your motor oil and filter every 3,000 miles to keep your engine running cleaner.
  • Change your vehicles air filter with every oil change to reduce emissions.
  • Check your tire pressure and replace worn tires to improve gas mileage.
  • Make sure to get your state inspection yearly and on time. If the vehicle fails any part of the inspection, especially the emissions test, there are programs that can help you fix the problem. Go to for more info.
