PUBLIC NOTICE | Proposed Type IV Amendment to Solid Waste Facility Plan for Southwest Regional Landfill

ADEQ has received an application from Republic Services, Inc. for a Type IV change to the solid waste facility plan for the Southwest Regional Landfill located in Buckeye, Ariz.


The Southwest Regional Landfill is a 305-acre municipal solid waste landfill that has been in operation since 1997. The Type IV change proposes a vertical expansion of 110 feet, which corresponds to a total height of 1,200 feet above mean sea level, and a lateral expansion of approximately 375 acres. The capacity of proposed lateral expansion plus the vertical expansion will provide an additional disposal volume of approximately 80 million cubic yards of airspace. The installation of one additional groundwater monitoring well is proposed as part of the application and revisions to the final grading, drainage plan and groundwater monitoring program.
