Since 1991, Weber-Morgan Health Department has operated a federally-mandated Mobile Source (I/M) Air Quality Program in an effort to meet EPA guidelines for healthy air in our community. This program focuses on helping drivers understand their role in our local air quality. WMHD works to educate local auto repair shop owners and technicians to monitor vehicles located within Weber County to reduce the impact of auto emissions on the particulate counts and gasses emitted into the air.


Air pollution can have long-term health effects for our residents. Children, elderly and those who have heart and lung diseases are especially sensitive. Weber-Morgan Health Department has developed this web page to help residents know what they can do to protect their health from these long-term effects and how they can help reduce air pollution in our community.


Please join us. Drive less by walking, biking or taking public transportation. Reduce idling, by shutting off your vehicle anytime it is stopped for more than a minute. Maintain your vehicle, by keeping up with your vehicle’s emission tests and keeping your car in good repair.
