Forms and Tools/Online Processes



EPA: Environmental Protection Agency

EPA Non-attainment Area: an area that has not met EPA standards for levels of the pollutant ozone. States containing non-attainment areas are required to develop plans for meeting the required standard.

Idling: the operation of an engine in the operating mode where: (a) the engine is not engaged in gear; (b) the engine operates at a speed at the revolutions per minute specified by the engine or vehicle manufacturer for when the accelerator is fully released; and (c) there is no load on the engine. (City of Arlington, Texas Amended Ordinance 08-076, 9/16/08)

GVWR: gross vehicle weight rating - the maximum allowable total weight of a road vehicle or trailer when loaded, i.e. including the weight of the vehicle itself plus fuel, passengers, cargo, and trailer tongue weight.

TAC: Texas Administrative Code

TCEQ: Texas Commission on Environmental Quality


Idling vehicles emit large quantities of greenhouse gases each year in the United States, and idle reduction technologies and practices are an important way to cut petroleum consumption and emissions. It has also been determined that these exhausts are toxic and that long-term exposure has the potential for increased health risk.

The University of Texas at Arlington is located in an EPA non-attainment area for ozone standards. Every effort must be given to improving our air quality. Idling of any vehicle for more than five minutes from April through October is prohibited in the City of Arlington, and violators are fined in accord with Texas Administrative Code 30.114.510.30-114.517.

Exhaust from idling engines poses an exposure to faculty, students, staff, drivers, operators, and the community at large. The University of Texas at Arlington, in support of the City of Arlington's sustainability initiatives, and as part of a good neighbor policy, has adopted a sustainability policy, which this procedure supports. UT Arlington's policies and procedures apply to all vehicles that are on the main campus or any of the University's offsite campuses or construction sites controlled by UT Arlington.
