Proposed new and modified sources must obtain state construction permits in which the applicant shows how the anticipated emissions will not exceed allowable limits. christmas black cat with coffee is this jolly enough pattern ugly sweater In nonattainment areas, emissions from new or modified sources must also be offset by reductions in emissions from existing sources. Originally, the act required that the NAAQS be attained by 1977 at the latest, but the states experienced widespread difficulty in complying with this deadline. As a result, the deadlines for achieving NAAQS have been extended several times. Under the 1990 amendments, most areas not in attainment with NAAQS must meet special compliance schedules, staggered according to the severity of an area’s air pollution problem. The amendments also established specific requirements for each nonattainment category, as described below.
The 1990 amendments also authorized appropriations for clean air programs through FY1998. The act has not been reauthorized since then. House rules require enactment of an authorization before an appropriation bill can be considered; but this requirement can be waived and frequently has been. Thus, while authorization of appropriations in the Clean Air Act has expired, programs have continued and have been funded. The act’s other legal authorities, to issue and enforce regulations, are, for the most part, permanent and are not affected by the lack of authorization. Changes to the act in 1990 included provisions to classify most nonattainment areas according to the extent to which they exceed the standard, tailoring deadlines, planning, and controls to each area’s status; tighten auto and other mobile source emission standards; require reformulated and alternative fuels in the most polluted areas; revise the air toxics section, establishing a new program of technology-based standards and addressing the problem of sudden,
