Colorado Gov. Jared Polis has appointed a Colorado Department of Public Health and Environment regulator to the Colorado Chemical Demilitarization Citizens’ Advisory Commission, or CAC.

“I want to welcome Colleen Brisnehan as a member of the CAC,” said Irene Kornelly, chair, CAC. “We look forward to working with her and are glad to have her join our group.”

Brisnehan is the CDPHE hazardous waste program manager, succeeding Doug Knappe, who departed his positions at the CDPHE and the CAC for a position with the Environmental Protection Agency. Brisnehan has worked 22 years in the CDPHE Hazardous Materials and Waste Management Division, which includes 19 years as an environmental protection specialist and three years as the CDPHE Superfund and site assessment unit leader.

“I am privileged to serve on the CAC and participate in key dialogue with federal and community partners,” Brisnehan said. “The commission serves a critical role in the chemical demilitarization program and helps ensure community interests are addressed throughout the life of this project. I look forward to serving in this role to help ensure the program is collaborative, inclusive and protective of the community.”
