Table of Contents

R307-102-1. Air Pollution Prohibited; Periodic Reports Required.

(1) Emission of air pollutants in sufficient quantities to cause air pollution as defined in R307-101-2 is prohibited. The State statute provides for penalties up to $50,000/day for violation of State statutes, regulations, rules or standards (See Section 19-2-115 for further details).

(2) Periodic Reports and Availability of Information. The owner or operator of any stationary air pollutant source in Utah shall furnish to the director the periodic reports required under Section 19-2-104(1)(c) and any other information as the director may deem necessary to determine whether the source is in compliance with Utah and Federal regulations and standards. The information thus obtained will be correlated with applicable emission standards or limitations and will be available to the public during normal business hours at the Division of Air Quality.

R307-102-2. Confidentiality of Information.

Any person submitting information pursuant to these regulations may request that such information be treated as a trade secret or on a confidential basis, in which case the director shall so treat such information. If no claim is made at the time of submission, the director may make the information available to the public without further notice. Information required to be disclosed to the public under State or Federal law may not be requested to be kept confidential. Justification supporting claims of confidentiality shall be provided at the time of submission on the information. Each page claimed "confidential" shall be marked "confidential business information" by the applicant and the confidential information on each page shall be clearly specified. Claims of confidentiality for the name and address of applicants for an approval order will be denied. Confidential information or any other information or report received by the director shall be available to EPA upon request and the person who submitted the information shall be notified simultaneously of its release to EPA.

R307-102-3. Reserved.


R307-102-4. Variances Authorized.

(1) Variance from these regulations may be granted by the Board as provided by law (See Section 19-2-113) unless prohibited by the Clean Air Act:

(a) to permit operation of an air pollution source for the time period involved in installing or constructing air pollution control equipment in accordance with a compliance schedule negotiated by the director and approved by the Board.

(b) to permit operation of an air pollution source where there is no practicable means known or available for adequate prevention, abatement or control of the air pollutants involved. Such a variance shall be only until the necessary means for prevention, abatement or control becomes known and available, subject to the use of substitute or alternate measures the Board may prescribe.

(c) to permit operation of an air pollution source where the control measures, because of their extent or cost, must be spread over a considerable period of time.

(2) Variance requests, as set forth in Section 19-2-113, may be submitted by the owner or operator who is in control of any plant, building, structure, establishment, process or equipment.

R307-102-5. No Reduction in Pay.

In accordance with paragraph 110(a)(6), Clean Air Act as amended August 1977, owners or operators may not temporarily reduce the pay of any employee by reason of the use of a supplemental or intermittent or other dispersion dependent control system for the purposes of meeting any air pollution requirement adopted pursuant to the Clean Air Act as amended August 1977.

R307-102-6. Emissions Standards.

Other provisions of R307 may require more stringent controls than listed herein, in which case those requirements must be met.
