Continuous Emission Monitoring Program

Five-Year Notice of Review and Statement of Continuation

DAR File No.: 42643
Filed: 03/08/2018 11:07:21 AM


Concise explanation of the particular statutory provisions under which the rule is enacted and how these provisions authorize or require the rule:

The Air Quality Board is allowed by Subsection 19-2-104(1)(c) to make rules "...requiring persons engaged in operations which result in air pollution to: (i) install, maintain, and use emission monitoring devices, as the board finds necessary; (ii) file periodic reports containing information relating to the rate, period of emission, and composition of the air contaminant; and (iii) provide access to records relating to emissions which cause or contribute to air pollution." Also, Subsection 19-2-104(3)(q) allows the Board to "...meet the requirements of federal air pollution laws." Federal provisions that require certain sources to conduct continuous monitoring include federal Clean Air Act Title IV, the Acid Rain program. In addition, 40 CFR Part 51, Appendix P, states that "This appendix P sets forth the minimum requirements for continuous emission monitoring and recording that each State Implementation Plan must include in order to be approved under the provisions of 40 CFR 51.165(b)." Rule R307-170 meets these provisions by specifying how certain sources of air pollution must comply with federal and state requirements to install and operate equipment that continuously monitors certain pollutants; it is approved by EPA as a part of Utah's state implementation plan.

Summary of written comments received during and since the last five-year review of the rule from interested persons supporting or opposing the rule:

There were no comments in opposition to or in support of this rule since the last five-year review.

Reasoned justification for continuation of the rule, including reasons why the agency disagrees with comments in opposition to the rule, if any:

Rule R307-170 ensures that large sources of air pollution do not exceed emission limits for air pollutants that are harmful to human health. In addition, Rule R307-170 is a component of Utah's State Implementation Plan (SIP), and cannot be removed from the SIP without EPA approval. Therefore, this rule should be continued.
