Final Project MOHAVE Report

On March 19, 1999, EPA released the final Project MOHAVE report, which assesses the extent to which the Mohave Generating Station, located in Laughlin, Nevada, contributes to visibility impairment at Grand Canyon National Park.

In 1991, the U.S. Congress directed EPA to conduct a study to determine the extent to which the Mohave Generating Station contributes to visibility impairment at the Grand Canyon National Park. Together with the National Park Service and the majority owners of the Mohave Generating Station, Southern California Edison, EPA conducted a monitoring, modeling, and data assessment project designed to estimate the power plant's contributions to haze at the Grand Canyon. This cooperative effort was named Project Measurement of Haze and Visibility Effects, more commonly referred to as Project MOHAVE. The final report is available here for downloading.
