SUSTAINABILITY February/March 2016 airportbusiness 25 "felt the biofilm was from the glycol used for aircraft deicing," Ryks says. The airport put best management practices into place immediately, among which were testing and monitoring of runoff and a collection pro- cess designed to pick up glycol from the aprons. "Basically what would happen is an aircraft would deice and then these large 'vacuums' would suck up as much of the glycol as possible," Ryks says. According to Ecklund, these changes enabled the airport to capture close to 30 percent of what had been flowing into the tributary. "However, there was still a fair amount of fluid going off in the general runoff," says Ryks. "And that wasn't acceptable." DEQ officials agreed, and its Water Resources Division reis- sued the airport's National Pollutant Discharge Elimination System (NPDES) permit in August 2013, which authorized the discharge of stormwater associated with deicing activities with one caveat: The airport needed to construct a natural treat- ment system for stormwater or aircraft deicing fluids by 2015. Airport officials then teamed with the DEQ to analyze options to further mitigate the problem. TURN A NEGATIVE INTO POSITIVE Neighbors were up in arms, believing the glycol runoff resulted in the deaths of fish and other creek wildlife as well as emitted an unpleasant odor in the area. But airport officials took the negative situation with vast public outcry and turned it into a positive. "We turned to the community to come up with a solution," says Ryks. Their first step was to assemble a stakeholders' adviso- ry committee that consisted of community individuals, DEQ experts, airline representatives, airport staff and consultants to review available options and select one to move forward with. The airport then used social media to announce the meetings and publicly posted infor- mation on an area of its Website devoted to the project. "We wanted to be very transparent and open, and I think we were very successful with that," says Ryks. Phoenix Sky Harbor Air Cargo Facility Calamos Corp.
