Wastewater Treatment Odor Control

On Wednesday, August 28, at a meeting with MillerCoors representatives, City Council shared frustration regarding odor at the wastewater treatment facility. Multiple concerns were expressed regarding this summer’s odors. The MillerCoors waste water treatment facility treats some waste water from the City of Golden, and treats brewery waste. MillerCoors indicated that they are aware of odor concerns and expressed willingness to evaluate plant modifications to reduce odors.

Staff from the City and MillerCoors met later the same day. During that meeting, the following commitments were made:

  • MillerCoors will respond to calls made to the Odor Hotline (303-277-2112). The message on the hotline will be changed to request specific location data to help MillerCoors verify odor sources. The waste water treatment unit operations are separated by distance.
  • MillerCoors recently hired an environmental consultant specializing in air pollution and odors. The consultant will investigate sources of odors at the waste water treatment facility.
  • Golden and MillerCoors staff will check in monthly to discuss progress made during the month and focus on communication with the community. We will post relevant updates on this page.
  • MillerCoors’ goal is to implement odor reductions.

Jefferson County Health Department conducted odor monitoring at the brewery on multiple days. This monitoring did not show any health violations at the brewery. While the health department inspections lead to no violations, MillerCoors affirms its commitment to the work to minimize the emission of odorous gasses.
