Comparison: State vs. Federal
• Rules. Colorado's air regulations require all sources with potential emissions above the state threshold to obtain a permit. Those sources with potential emissions above the Title V thresholds must obtain a Title V operating permit. The Colorado Title V operating program follows the federal provisions, including provisions establishing greenhouse gas permitting thresholds, and received full approval from the U.S. Environmental Protection Agency (EPA).
• Administration and enforcement. The APCD of Colorado's Office of Environment is responsible for the administration and enforcement of the state's Title V program.
