Change in Proposed Rule

DAR File No.: 36732
Filed: 12/10/2012 12:50:10 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

During the public comment period the Division of Air Quality (DAQ) received comments from industry that identified some overlap in this proposed rule and the proposed Rule R307-355 (DAR No. 36737). Industry also provided recommendations regarding exemptions to the rule, additional definitions, and other suggested language that was intended to clarify the requirements of the rule. The EPA also submitted comments regarding record-keeping, including VOC limits on cleaning solvents, and requirements and director's discretion language within the rule. Several substantive changes to the proposed rule have been made as a result of the comments from industry and EPA.

Summary of the rule or change:

Section R307-350-2 is changed stating that in Tooele and Box Elder counties, the rule applies to existing sources as of 02/01/2013, that have the potential to emit 5 tons per year or more of VOC and applies to new sources that have the potential to emit 2.7 tons per year or more VOC. The rule still applies in Cache, Davis, Salt Lake, Utah, and Weber counties to sources that have the potential to emit 2.7 tons per year or more VOC. The exemptions section of the rule was changed by adding surface coating of aerospace vehicles and components and military munitions manufactured by or for the Armed Forces of the United States as exempt from Rule R307-350. A definition for "Aerospace vehicles and component" was added to Section R307-350-4. Language is added to Section R307-350-5 to clarify that exempt solvents are not included in the VOC content limits for the coating used. Section R307-350-6 is changed by adding electrodeposition as an acceptable application method. A VOC content for cleaning material is added to Section R307-350-7. Section R307-350-7 is also changed to require owners and operators to maintain records demonstrating compliance with the rule on an annual basis and to require them to make those records available to the director upon request. (DAR NOTE: This change in proposed rule has been filed to make additional changes to a proposed new rule that was published in the October 1, 2012, issue of the Utah State Bulletin, on page 76. Underlining in the rule below indicates text that has been added since the publication of the proposed rule mentioned above; strike-out indicates text that has been deleted. You must view the change in proposed rule and the proposed new rule together to understand all of the changes that will be enforceable should the agency make this rule effective.)

State statutory or constitutional authorization for this rule:

• Subsection 19-2-104(1)(a)

Anticipated cost or savings to:

the state budget:

The changes to this rule do not result in any new requirements to the state; therefore, there are no anticipated costs or savings to the state budget.

local governments:

The changes to this rule do not result in any new requirements to local governments; therefore, there are no anticipated costs or savings to local governments.

small businesses:

Because the rule's applicability to existing sources in Box Elder and Tooele counties is changed from sources with the potential to emit 2.7 tons per year VOC to sources with the the potential to emit 5 tons per year VOC, the rule will apply to fewer sources in those counties, resulting in a savings from $238 up to $2,020 per ton of VOC removed.

persons other than small businesses, businesses, or local governmental entities:

Because there are no new requirements for persons other than small businesses, businesses, or local government entities, there are no anticipated costs or savings.

Compliance costs for affected persons:

Because the rule's applicability to existing sources in Box Elder and Tooele counties is changed from sources with the potential to emit 2.7 tons per year VOC to sources with the the potential to emit 5 tons per year VOC, the rule will apply to fewer sources in those counties, resulting in a savings from $238 up to $2,020 per ton of VOC removed.

Comments by the department head on the fiscal impact the rule may have on businesses:

Because the rule's applicability to existing sources in Box Elder and Tooele counties is changed from sources with the potential to emit 2.7 tons per year VOC to sources with the the potential to emit 5 tons per year VOC, the rule will apply to fewer sources in those counties, resulting in a savings from $238 up to $2,020 per ton of VOC removed.
