Abstract |
Under the Clean Air Act Amendments of 1977, States must submit revisions to their State Implementation Plans (SIPs) for all areas that are not attaining the national ambient air quality standards. EPA held a series of three two-day workshops to discuss provisions of those Act Amendments that pertain specifically to nonattainment areas. The objective of the workshops was to outline the criteria for an acceptable 1979 plan. The workshops discussed the major portions of an implementation plan revision and provided guidance on specific items that must be part of the plan. While details of actual preparation of the SIP revision were not discussed, references were made to sources of this information. This compilation contains the visual aids used by the presenters, followed by textual material supporting the presentations. The material is arranged in order of presentation. The material is restricted to the requirements for the nonattainment area SIPs. |
