Regional Haze Rule Implementation - Reasonable Progress Analysis Support

The Western Regional Air Partnership (WRAP) has worked cooperatively with western state air agency representatives to prepare a Regional Haze Rule (RHR) progress report technical support document. The primary contractor for this effort was Air Resource Specialists, Inc. (ARS).

This document is intended to provide the technical basis for use by Western States to develop the first of their individual reasonable progress reports. It includes background information, and regional, state, and Class I area (CIA) specific summaries that characterize the difference between baseline conditions (2000-2004) and first successive progress period (2005-2009). Specific regulatory questions addressed in this report include:

  • What are the current visibility conditions for the most impaired (worst) and least impaired (best) days?
  • What is the difference between current visibility conditions and baseline conditions for the most impaired and least impaired days?
  • What is the change in emissions that occurred between the baseline period and the progress period?
