Less regional haze is expected at Grand Canyon National Park after Salt River Project finished installing new emissions-control equipment at the Navajo Generation Station near Page.
The Tempe-based utility says installation of the smog reducing equipment is intended to help cut nitrogen oxide emissions along the Colorado Plateau, including the Grand Canyon, by at least 40
SRP says that should equal a reduction of approximately 14,000 tons of nitrogen oxides annually.
When released into the atmosphere, nitrogen oxides create particles that contribute to the regional haze.
SRP says the equipment is the last of three project installations.
The Navajo Generating Station is located about 80 miles from the Grand Canyon's main visitor area on the South Rim.
