Oil and Gas Industry: Tank Trunk Loading

Five-Year Notice of Review and Statement of Continuation

DAR File No.: 44041
Filed: 09/05/2019 09:43:44 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 (Board) is allowed by Subsection 19-2-104(1)(a) to make rules "... regarding the control, abatement, and prevention of air pollution from all sources and the establishment of the maximum quantity of air pollutants that may be emitted by an air pollutant source." Also, Subsection 19-2-104(3)(q) allows the Board to "...meet the requirements of federal air pollution laws." In 2012, the state of Utah entered into EPA's Ozone Advance Program with the goal to proactively lower ozone values in the Uintah Basin. Ozone is created by photochemical reaction, and the main precursors are volatile organic compounds (VOC) and oxides of nitrogen (NOx). In the Uintah Basin, oil and gas production accounts for 97% of anthropogenic VOC emissions. The General Approval Order for a Crude Oil and Natural Gas Well Site and/or Tank Battery contains a requirement that all tanker trucks loading on-site use either bottom filling or submerged filling to reduce VOC emissions created by splashing of liquids when loading oil, condensate, or produced water. Rule R307-504 expands this requirement to all existing operations.

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

No comments were received since this rule was first made effective five years ago.

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

Since January 1, 2015, tank trucks used for intermediate hydrocarbon liquid or produced water are required to load using bottom filling or submerged fill pipe. This rule applies to any person who loads or permits the loading of any intermediate hydrocarbon liquid or produced water at a well production facility. Ozone continues to be monitored at levels above the National Ambient Air Quality Standard along the Wasatch Front and Uintah Basin. As operators have already invested to comply with this rule there is no additional impact to continue to comply and reduce emissions of ozone precursors. Therefore, this rule should be continued.
