BOULDER — Boulder County has submitted its application for 5-Star certification with the Colorado Department of Public Health and Environment. The business-variance program allows participating businesses to operate one level above Boulder County’s position on the statewide dial, provided that they demonstrate compliance with enhanced public-health guidelines and safety precautions to prevent the spread of COVID-19. Locally, Broomfield and Larimer counties already have authorization for 5-Star programs. Weld County has not applied, but the city of Greeley, the city of Evans, the town of Windsor and the Greeley Area Chamber of Commerce have launched a program. The Boulder County 5 Star Program Administrative Committee submitted its program application to the state Wednesday, having received support from required stakeholders, including Boulder County Public Health, Boulder County Commissioners, hospitals across the county, and law enforcement.
