RULE 215. Public Availability of Emission Data

A. The owner or operator of any stationary source within the Great Basin Unified Air Pollution Control District shall, upon notification from the Air Pollution Control Officer, maintain records of the nature and amounts of emissions from such source and/or any other information as may be deemed necessary by the Air Pollution Control Officer to determine whether such source is in compliance with applicable emission limitations or other control measures.

B. The information recorded shall be summarized and reported to the Air Pollution Control Officer on forms furnished by the Great Basin Unified Air Pollution Control District and shall be submitted within 30 days after the end of the reporting period. Reporting periods are January 1 - June 30 and July 1 - December 31, except that the initial reporting period shall commence on the date the Air Pollution Control Officer issues notification of the record keeping requirements.

C. Information recorded by the owner or operator and copies of the summarizing reports submitted to the Air Pollution Control Officer shall be retained by the owner or operator for two years after the date on which the pertinent report is submitted.

D. Emission data obtained from owners or operators of stationary sources pursuant to this paragraph will be correlated with

applicable emission limitations and other control measures and will be available to the public during normal business hours at the District's Office.

E. Request for public records should be specific and in sufficient detail that the District may readily identify the specific information requested. However, the owner of a source may request that information provided to the Air Pollution Control District, which information shall not include actual emission data, be treated as a trade secret pursuant to Government Code Section 6254.7. Written justification for such requests are to be submitted to the Air Pollution Control District, and such justification will be considered public record. The Air Pollution Control Officer shall rule upon requests for trade secret status within thirty (30) days of receipt of such request.
