Alternative AIMM public notices
According to Air Quality Control Commission (AQCC) Regulation No. 7, Section XII.L.8, an Alternative Approved Instrument Monitoring Method (AIMM) that the Air Pollution Control Division (Division) has approved for use in the ozone non-attainment area is required to be posted to public notice and approved by the EPA.
During a public notice period, the Division posts the submitted Alternative AIMM application, draft approval letter, and application analysis documents on this webpage and requests written comments from the public. Any confidential business information (CBI) included in the Alternative AIMM application must be marked as such in order to be processed by the Division as CBI according to the Colorado Department of Public Health & Environment’s CBI policy. An Alternative AIMM application with CBI will have a redacted version of the application (minus CBI) posted for public notice.
If you would like to submit a public comment for an Alternative AIMM application and draft approval, please first review our Public Participation Guidance. Although this information is specific to public comments for permits, it is also applicable to public comments for Alternative AIMM applications.
