Pursuant to a legislative requirement, GAO reviewed the National Highway Traffic Safety Administration's (NHTSA) new rule on the average fuel economy standards for light trucks. GAO noted that: (1) NHTSA interprets section 322 of the Omnibus Consolidated and Emergency Supplemental Appropriations Act for fiscal year 1999 as requiring it to prescribe the same light truck corporate average fuel economy standard for model year 2001 that applies to model year 2000; (2) accordingly, the rule continues the 20.7 miles per gallon standard for 2001; (3) this is the same interpretation NHTSA has applied for the three preceding model years and Congress has continued to insert the same language in the yearly Appropriations Acts and has not objected to NHTSA's interpretation; and (4) NHTSA complied with the applicable requirements in promulgating the rule.
