Brigham Young University is requiring students who want campus parking permits to obtain emission inspections on their vehicles.

Lt. Michael Harroun, manager of BYU Traffic Services, said the new policy, which begins immediately, will significantly contribute to the control of air pollution in Utah County."We realize this may be an inconvenience to some, but it is a necessary part of what we all must do to preserve and improve air quality in our cities," Harroun said.

The new policy is being implemented in support of Provo's program to curb air pollution, BYU Executive Vice President John B. Stohlton said. Without such programs, the city and BYU could face possible Environmental Protection Agency sanctions, including a ban on construction projects.

BYU's new program applies to all vehicles from 1968 and later, except motorcycles, mopeds and vehicles with diesel engines.

Harroun said students from areas where vehicle emission tests already are required - including Salt Lake, Utah and Davis counties - need bring only their vehicle registrations as proof of compliance.

Harroun estimates that of the 10,333 parking permits issued to students last year, 1,500 to 2,000 were for vehicles coming from areas where no emission control inspection is required.
