AGGREGATES MANAGER / March 2018 17 PLANT PROFILE refresher training, we will have an MSHA inspector come and speak with the group. We want to make sure everyone is prepared for properly inspecting their plant and equipment each day. MSHA inspectors constantly preach that, if we do a proper work- place exam and pre-shift equipment inspection, we've probably knocked out 99 percent of the situations that could result in a citation. That's why we concentrate on that." Environmental compliance A signifi cant portion of Maricopa County, the county in which Peoria Pit is located, has been deemed a "nonattainment" area for PM 10 by the U.S. Environmental Protection Agency and the Arizona Department of Environmental Quality (ADEQ). PM 10 is particulate material 10 microns or smaller, which includes soot, dust, and other small bits of solid material released into the air. "The air quality permit that we have through the ADEQ has strict re- quirements on crushing and screening operations to control dust pollution," Palmer says. "These measures include regular dirt road watering, installing water spray bars on material transfer points of the crushing and screening plant, and keeping below production throughput limits." ADEQ also performs regular compliance inspections to ensure that the company is adhering to its permit conditions. "We take pride in the fact that ADEQ inspectors are always pleased with how our site looks upon their arrival for a compliance inspec- tion," Palmer adds. "These inspections are always unannounced to ensure that we are complying all of the time and not just when they are on site." Core Materials also must comply with air quality regulations. It has a permit through Maricopa County, which conducts regular inspections of its operations. This means that the county's eyes are on Southwest Rock Product's operation as well. After leaving the attrition cells, sand travels through a sand screw and across the dewatering screen before being carried up the radial stacker to be stockpiled. 1.888.862.7461 www. beka-lube.com BEKA - LUBRICATION SPECIALISTS SINCE 1927 BEKA auto-lube is built to take the bumps and grinds of a hard-working life on the road or off.
