To date, the Commission process for addressing the multi-faceted nature of 

 regional transport of pollution has been very successful. The Commission has 

 identified a range of management options for addressing regional haze which 

 includes market-based approaches for reaching visibility targets and incentive 

 programs for reducing emissions causing visibility impairment. The Commission 

 has also approved criteria for evaluating different combinations of these 

 management options, such as their effectiveness in reducing visibility impairment, 

 cost of implementation, energy impacts, equity, as well as social and other 

 environmental effects. The Commission will review specific combinations of these 

 emission management options and, using the criteria, develop final 

 recommendations for EPA by November 1995. 



EPA has provided substantial support to the Commission. Much of the 

 technical support has been provided through a major research effort called Project 

 MOHAVE. The study is managed by EPA and the Southern California Edison 

 Company with contributions from the California Air Resources Board, the Electric 

 Power Research Institute, the National Oceanic and Atmospheric Administration, 

 the National Park Service, the University of Nevada Desert Research Institute, and 

 the U.S. Department of Energy. Project MOHAVE represents an effort exceeding 

 $8.5 million. Begun in 1991, the study's primary focus has been to determine the 

 impact of the Mohave Power Project (a coal-fired electric generating station) on 

 visibility in Grand Canyon National Park. EPA and the other study sponsors have 

 since broadened the original study goal to include a field study and assessment 

 effort capable of estimating regional source impacts on the Grand Canyon National 

 Park as well as other nearby class I areas with the specific purpose of assisting the 

 work of the Grand Canyon Commission. The data from this study are still being 

 analyzed and a report is due at the end of this year. EPA and the other sponsors 

 have shared much of the technical knowledge about transport and aerosol
