Rule R307-355

Control of Emissions from Aerospace Manufacture and Rework Facilities

Notice of Proposed Rule

(New Rule)

DAR File No.: 36737
Filed: 09/06/2012 05:44:21 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

In 2006, EPA tightened the 24-hour PM2.5 national ambient air quality standard from 65 to 35 micrograms per cubic meter. Currently, seven Utah counties have been found by EPA to not meet this standard. Coatings operations, organic solvent cleansing, and storage and disposal of solvents at aerospace manufacture and rework facilities emit volatile organic compounds (VOCs), which are precursors to the formation of PM2.5. This rule for the PM2.5 State Implementation Plan will lower VOCs that are emitted from these operations.

Summary of the rule or change:

This rule applies to aerospace manufacture and rework facilities that have the potential to emit five tons of volatile organic compounds (VOC) per year and that are located in Box Elder, Cache, Davis, Salt Lake, Tooele, Utah, and Weber counties. The rule establishes reasonably available control technology requirements to reduce VOC emissions. Owners and operators have the option to reduce VOCs by applying coatings with the VOC limits established in the rule or to use add-on controls to achieve at least a 95% VOC reduction. Coating application methods and work practices for cleaning materials are established. Owners and operators are required to maintain records from the manufacturer that demonstrate compliance with the emission standards in the rule. Hand-wipe, flush, and spray gun cleaning requirements are included in the rule. During the public comment period, the Air Quality Board is requesting public input on the appropriateness of applying this rule in Tooele and Box Elder counties and is asking industry to provide information on their cost to comply with the rule.

State statutory or constitutional authorization for this rule:

• Subsection 19-2-104(1)(a)

Anticipated cost or savings to:

the state budget:

There may some an increase in administrative costs at the Division of Air Quality; however, costs should be minimal. Therefore, there are no anticipated costs or savings to the state budget.

local governments:

This rule does not add any requirements to local government; therefore, there are no anticipated costs or savings.

small businesses:

The division does anticipate a cost to small businesses to implement this rule. However, the division is unsure of what those costs would be. That is why during the public comment period, the Air Quality Board is asking that industry provide cost information.

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

This rule applies to aerospace manufacture and rework facilities that have the potential to emit five tons of volatile organic compounds (VOC) per year. There are no anticipated costs or savings to persons other than small businesses, businesses, or local government entities.

Compliance costs for affected persons:

The division does anticipate compliance costs for affected persons. However, the division is unsure of what those costs would be. That is why during the public comment period, the Air Quality Board is asking that industry provide cost information.

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

The division does anticipate compliance costs for affected persons. However, the division is unsure of what those costs would be. That is why during the public comment period, the Air Quality Board is asking that industry provide cost information.

R307-355-4. Definitions.

The following additional definitions apply to R307-355:

"Aerospace manufacture" and "rework facility" means any installation that produces, reworks, or repairs in any amount any commercial, civil, or military aerospace vehicle or component.

"Specialty coating" means specialty coating as defined in 40 CFR 63 subpart GG, Appendix A, which is incorporated by reference.
