The following documents represent various Air Pollution Control Program decisions involving rules, policies, and procedures. In most cases, these are clarifications or interpretations of existing rules that were documented as a result of a question or comment from a regulated source or local agency. These documents are intended to provide background or history of the program's decisions relative to the rule or guidance in question. These documents are not rules in and of themselves, and therefore, are subject to revision or reinterpretation as necessary or appropriate. If you have any questions about any of these documents, please contact the Air Pollution Control Program.
