Thank you for the opportunity to submit comments on the Environmental Protection Agency’s (EPA) revised intended Air Quality Designations for the 2015 Ozone National Ambient Air Quality Standards. The following comments pertain to the designation for Weld County, Colorado and its inclusion in the Denver Metro/North Front Range ozone nonattainment area. We are pleased that EPA has, following a federal court decision, reversed its prior decision to exclude the northern portion of Weld County.
