If these data show that standards would be exceeded, halloween horse full printing christmas ugly sweater the state must impose additional controls on existing sources to ensure that emissions do not cause “exceedances” of the standards.

on in-use performance over time, on warranties for the most expensive emission control components (8 years/80,000 miles for the catalytic converter, electronic emissions control unit, halloween horse full printing christmas ugly sweater and onboard emissions diagnostic unit), and on certification (an auto’s useful life was defined as 100,000 miles instead of the earlier 50,000 miles—a figure since increased through regulation to 120,000 or 150,000 miles depending on the standards). Regulations were also extended to include nonroad fuels and engines. Use of alternative fuels and development of cleaner engines was also to be stimulated by the Clean Fuel Fleet Program. In all of the most seriously polluted ozone and CO nonattainment areas, centrally fueled fleets of 10 or more passenger cars and light-duty trucks had to purchase at least 30%
clean-fuel vehicles when they add new vehicles to existing fleets, starting in 1999. (The act originally required the program to begin in 1998, but the start was delayed by a year.) The percentage rose to 50% in 2000 and 70% in 2001. Heavy-duty fleets were required to purchase at least 50% clean-fuel vehicles annually. A clean-fuel vehicle is one which meets Low Emission Vehicle standards and operates on reformulated gasoline, reformulated diesel, methanol, ethanol, natural gas, liquefied petroleum gas, hydrogen, or electricity. Improve monitoring, in order to obtain more comprehensive and representative data on ozone pollution. Although areas with more severe air pollution problems have a longer time to meet the standards, more stringent control requirements are imposed in areas with worse pollution. A summary of the primary ozone control requirements for each nonattainment category follows. SIPs are based on emission inventories and computer models to determine whether air quality violations will occur.
