Answer from Weld County:
At the time of this specific permit being submitted to and considered by Weld County, there were no air monitoring rules or requirements in County Code. The Operator has voluntarily committed to air monitoring at this Location. Even in our updated County Code, air monitoring is not a requirement at all Locations, and the Code specifically mentions that Operators must follow State and Federal rules. Many Operators are voluntarily agreeing to air monitoring to have evidence of compliance with all State and Federal rules. Current County Code addresses Air Permits in Sec. 21-5-480.
