Stormwater Pollution Prevention


Rain water runoff in and around McKinney drains directly to the East Fork of the Trinity River, as well as Wilson Creek and Lake Lavon. Lake Lavon is a critical source of drinking water for McKinney and other local communities.

Since most surface water pollution comes from stormwater contamination, McKinney National Airport strives to control pollution at its source. This means informing all airport users of ways to keep stormwater clean. Here are a few tips.

Proactive Stormwater Management


McKinney National Airport (MNA) and the operator of each facility on the airport work together to ensure that the airport's stormwater is pollutant-free through the implementation of a Stormwater Pollution Prevention Plan (SWPPP). The SWPPP identifies potential sources of pollution and employs proactive measures that prevent the contamination of stormwater leaving MNA.

Stormwater Pollution Must Be Prevented at the Source


Did you know that rainwater that runs off of buildings, hangars and paved surfaces at the airport drains to surface waters in North Texas? Those waterways include the East
Fork of the Trinity River, Wilson Creek and Lake Lavon. Lake Lavon is a critical reservoir for our community's irrigation and drinking water.
Not coincidentally, the majority of surface water pollution in the United States comes from stormwater contamination (engine oil leaks, hazardous waste dumping, litter, etc.)

The only practical solution is to control pollutants at their source to the maximum extent possible. Controlling contaminates that could pollute stormwater at MNA begins with each business, employee, tenant and user.

Pollution Prevention is Only Possible with Your Assistance
The overall success of the SWPPP depends on you. MNA asks that you help keep our stormwater pollutant-free by following these guidelines:

After leaving MNA property, stormwater flows to Lake Lavon. Among other uses, Lake Lavon provides a source of drinking water to North Texas.
  • Take advantage of recycling programs to dispose of used oil, tires and batteries. Several used oil stations are available on the airport for your convenience. Contact MNA administration for details.
  • Wash aircraft on a MNA-approved outdoor wash rack or inside a hangar equipped with floor drains connected to the sanitary sewer system.
  • Dispose of hangar floor wash water in the sanitary sewer only.
  • Employ good housekeeping measures. Store materials indoors in labeled and sealed containers, maintain clean facilities and dispose of trash properly.
  • Ensure that trash receptacles are covered and do not leave any garbage next to a dumpster.
  • Properly dispose of waste anti-freeze, hydraulic fluid and other hazardous materials.
  • Conduct preventative maintenance and repairs on aircraft and equipment inside approved maintenance facilities.
  • Do not "top off" fuel tanks so expanded fuel leaks on the ground during warmer summer months.
  • Purchase a strainer to sump fuel and reuse uncontaminated AvGas. Fuel samples dumped onto pavements wastes money and pollutes stormwater.
  • Always use a drip pan when conducting maintenance activities on aircraft and equipment.
  • Learn more about MNA spill management procedures.
