Lawn and Garden Equipment Page

Beginning June 1, 2025, state agencies cannot use gasoline-powered push and hand-held lawn and garden equipment with an internal combustion engine smaller than 19kw (25 horsepower) from June 1 to August 31.

Beginning June 1, 2026, and by June 1 of each following year, the university must submit a report for the prior calendar year to the Colorado Department of Public Health and Environment (CDPHE) Air Pollution Control Division (APCD). The report must include a list of subject lawn and garden equipment that was used or might have been used from June 1 to August 31 of the previous year.
