Quieter, Costlier Trucks
Fire apparatus is destined to become quieter—and more costly—under noise emission standards promulgated by the federal Environmental Protection Agency. The new regulation, published in the Federal Register of April 13, sets a maximum sound level of 83dBA effective January 1, 1978, and a maximum sound level of 80 dBA effective January 1, 1982. The regulation affects all trucks of more than 10,000 pounds, gross vehicle weight rating.
Noise control for cooling, exhaust, engine and air intake, the EPA stated, is expected to add $426 to the cost of medium diesel trucks and $356 to the cost of heavy diesel trucks by 1978. The 1982 requirement, the EPA estimated, will add $850 and $589 to the costs of medium and heavy diesel trucks, respectively.
