Imperial County APCD does not anticipate any emissions changes or any 

significant impacts to regulated sources or the APCD resulting from the amendments to 

Rule 101.

EPA Evaluation

The changes to Rule 101 are mostly administrative and they will have no negative 

impact on the environment or Clean Air Act requirements.

EPA is recommending approval of Imperial County APCD Rule 101 under 

section 110(k) as meeting the requirements of section 110(a) and Part D of the Clean Air 

Act, as amended in 1990. Approval of the definitions in Rule 101 should not be 

interpreted as EPA approval of the other rules in which these definitions are used.
