Abstract

This paper was developed to evaluate the implications of U.S. Environmental Protection Agency’s proposed improvements to the current CAL3QHC model used to determine emission concentrations at intersections. It evaluates several variables used in the program by performing statistical analyses to define the variables having the strongest correlations in influencing the emission concentrations at intersections.

Abstract

Phase I of this research effort is geared toward analysis of national air quality trends within selected metropolitan planning areas. Emphasis is placed on ozone, the spational variability in the formation of ozone pollution, and correlation of trends and projections with programs and implementation of technologies required under the 1990 Clean Air Act Amendments (CAAAs). Phase II is a continuation of this effort.

Abstract

This brochure provides an overview of the 1990 Clean Air Act Amendments (CAAAs) and the planning requirements for State Implementation Plan (SIP) development. It discusses the effects of pollution on human health and how transportation planning assists in advancing the clean air goals of the CAAAs. The foldouts of the pamphlets provide colored tables illustrating the necessary planning requirements by severity and pollutant type. The brochure also attempts to provide definitions of the transportation conformity process and how ISTEA planning relates to the development of SIPs for attainment of the National Ambient Air Quality Standards (NAAQS). A listing of regional air quality specialists is provided in the appendix for additional questions or information.
