PUBLIC NOTICE | Draft Hazardous Waste Permit Available for Conn-Selmer, Inc.
A draft hazardous waste permit has been prepared for Conn-Selmer, Inc.:
Conn-Selmer, Inc. (CSI) groundwater remedation system (GRS)
1310 W. Fairway Drive
Nogales, Arizona 85621
The GRS is designed to remove volatile organic compounds (VOCs) from the groundwater. The VOC contamination is the result of improper storage of wastes during musical instrument manufacturing operations, and occurring from 1966 through 1985. The GRS is a pump and treat system and pumps groundwater from an extraction well at the source of contamination to a 7,000-gallon equalization tank. The contaminated groundwater is then pumped at 50-75 gallons per minute (gpm) through two air strippers, in series. Each air stripper is 28 feet tall, has an inside diameter of 3.5 feet, and contains packing material to maximize exposure of contaminated groundwater to air introduced by fans countercurrent to water flow. The clean, treated groundwater is sent to an impoundment located at the former-Palo Duro Creek Golf Course for storage. The draft permit would allow the facility to operate the GRS and remove the VOCs from the groundwater in accordance with Arizona rules established to protect human health and the environment. The permit would be effective for ten (10) years. No hazardous waste storage or disposal units would be permitted at this site.
