The most significant change in the regulations is the revised evaporative emission test procedure which applies to both light duty vehicles and light duty trucks. The standard 6 g/test is established for the 1978 model year which appears to be higher than the present 2 g/test standard as measured by the ''carbon trap method.'' However, when the 6 g/test standard is required to be met by the new test procedure, evaporative hydrocarbons emissions will be reduced from about 1.76 g/mile to 0.6 g/mile. This action will reduce nationwide hydrocarbon emissions from all mobile sources by as much as 46 percent by the year 1990. For certain Air Quality Control Regions that are expected to have difficulty meeting the ambient air quality standards for oxidants, this action will reduce hydrocarbon emissions from all sources by 7.8 percent by the year 1985. It is estimated that the increased retail cost to the consumer will average about $7.30 for control system components to meet the new evaporative emission standard. No lifetime costs due to increased fuel consumption or maintenance are expected.
