DEQ approves license for City of Billings Landfill Expansion

Monday, December 17, 2018/Categories: Department of Environmental Quality/Tags:

HELENA – The Montana Department of Environmental Quality today approved the City of Billings’ application for a Class II solid waste management system license to expand its regional landfill.


The approval follows a comprehensive review process that included an in-depth environmental analysis, as well as multiple public meetings and an extended public comment period. DEQ received a total of 585 comments, all of which were compiled and responded to in the Final Environmental Assessment (EA) document released today in conjunction with the license approval. The City submitted its initial application for the expansion in April 2015.


“We appreciate the public’s input, which was invaluable in helping us conduct a comprehensive and sound environmental review,” said Jenny Chambers, Administrator of DEQ’s Waste Management & Remediation Division. “We’ve addressed community concerns to the full extent possible, asking the City to make several rounds of changes to its application, including the installation of liners and leachate collection systems as an added protection for groundwater. The project now meets the requirements of the Montana Solid Waste Management Act.”


The Yellowstone County Health Officer has 15 days to sign the license, at which point it becomes effective and the City may proceed. If the County Health Officer does not approve the license, the City may appeal to the Montana Board of Environmental Review within 30 days of receipt of written notice.


The license and full Environmental Assessment document are available at:


The project will expand the existing landfill boundary by 350 acres on city-owned property south of the current facility. Total disturbance will be 293 acres for disposal units, roads, buildings and retention ponds; however, the maximum area open at any given time will be 119 acres. Impacts to groundwater were among the community’s chief concerns. DEQ’s Environmental Assessment included 57 test pits and 31 test borings, one of which reached a depth of 300 feet and still encountered no groundwater. Groundwater was found only in one localized area at the site, which has excellent natural barriers to prevent contamination. The City of Billings will install liners and leachate collection systems for all municipal waste cells.
