Metropolitan St Louis Sewer District meets MACT standards deadline with help from Black & Veatch
Wet scrubber technology provides advanced control of particulates, metals, and acid gases from the incinerator exhaust gas to reduce air emissions.
OVERLAND PARK, KS, May 10, 2016 -- The Metropolitan St. Louis Sewer District (MSD) successfully met a March 21 deadline for new MACT standards when Phase 2 of their $13 million incinerator air emissions upgrade program went on-line and passed air quality emissions performance tests. At MSD’s two largest wastewater treatment plants, Black & Veatch lead the program that ensured MSD is meeting new federal air emission limits for existing and new sewage sludge incinerators.
In 2011, the U.S. Environmental Protection Agency issued new air emission limits for existing and new sewage sludge incinerators. Facing the compliance deadline in less than 21 months, Black & Veatch was selected to work with MSD to implement an accelerated design, procure the long lead time, multiple venturi wet scrubber equipment, and phase construction at the two plants to assure incineration capacity modified with the new air emissions equipment was online and operational by the March 21, 2016 deadline. During performance tests the week of March 14, the Bissell Point and Lemay plants met the Maximum Achievable Control Technology (MACT) requirements mandated by the EPA. Together, the Bissell Point and Lemay plants incinerate 75 percent of all solids generated by the MSD service area.
The company has completed similar work in Detroit and Indianapolis. In addition, Black & Veatch provided design, permitting and construction management for a new incinerator facility for the Little Blue Valley Sewer District in Eastern Jackson County, Missouri. It was the first in the state of Missouri to be permitted under the new MACT SSI standards.
For the St. Louis project, Black & Veatch used laser scanning and 3D modeling to develop plans for integrating the new equipment into the continually operating facility. The facility was built in the 1960s and there were no comprehensive drawings available for reference. The company devised a phased, accelerated construction schedule to meet EPA’s timetable for compliance, with completion of Phase 2 by the March 2016 deadline. All phases of the work are on schedule to be completed by July 2016, when a total of four incinerators at Bissell and three at the Lemay plant will be fully outfitted with the wet scrubber equipment.
