Change in Proposed Rule

DAR File No.: 38683
Filed: 10/07/2014 10:02:54 AM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The EPA has indicated its intention to approve the area source coatings rules for the PM2.5 State Implementation Plan as reasonable available control technology (RACT), but not until: 1) they are amended to clarify that the amount of control removal specified in each rule is based on the entire system, and 2) the inspection and recordkeeping requirements for these systems are expanded. These changes were proposed to this and 13 other air quality area source rules, and a 30-day public comment period was held. During the public comment period, several inquiries were made regarding why the rules do not permit the use of exempt solvents for cleaning. The definition of "volatile organic compound (VOC)" found in Section R307-101-2 incorporates the definition of VOC found in 40 CFR 51.100(s)(1). This definition does permit the use of exempt compounds for cleaning; however, this allowance is not explicitly stated in this or the other proposed area source rules. The change to the proposed rule is to specify that exempt compounds are not VOC by definition.

Summary of the rule or change:

The change clarifies that exempt compounds are not VOC by definition. (DAR NOTE: The original proposed amendment upon which this change in proposed rule (CPR) was based was published in the August 1, 2014, issue of the Utah State Bulletin, on page 32. 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 CPR and the proposed amendment 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:

This change is to add clarifying language and does not change any of the rule requirements; therefore, there are no anticipated costs or savings to the state budget.

local governments:

This change is to add clarifying language and does not change any of the rule requirements; therefore, there are no anticipated costs or savings to local government.

small businesses:

This change is to add clarifying language and does not change any of the rule requirements; therefore, there are no anticipated costs or savings to small businesses.

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

This change is to add clarifying language and does not change any of the rule requirements; therefore, there are no anticipated costs or savings to persons other than small businesses, businesses, or local government entities.

Compliance costs for affected persons:

This change is to add language to clarify that exempt compounds are not VOC by definition. This change does not result in any additional compliance costs.

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

This change is to add language to clarify that exempt compounds are not VOC by definition. This change will not have a fiscal impact on businesses.

R307-350-6. Application Methods.

No owner or operator of a facility shall apply VOC containing coatings to metal parts and products unless the coating is applied with equipment operated according to the equipment manufacturer specifications, and by the use of one of the following methods:

(1) Electrostatic application;

(2) Flow coat;

(3) Dip/electrodeposition coat;

R307-350-7. Work Practices and Recordkeeping.

(1) Control techniques and work practices shall be implemented at all times to reduce VOC emissions. Control techniques and work practices shall include, but are not limited to:

(a) Storing all VOC-containing coatings, thinners, and coating-related waste materials in closed containers;

(b) Ensuring that mixing and storage containers used for VOC-containing coatings, thinners, and coating-related waste material are kept closed at all times except when depositing or removing these materials;

(c) Minimizing spills of VOC-containing coatings, thinners, and coating-related waste materials; and

(d) Conveying VOC-containing coatings, thinners, and coating-related waste materials from one location to another in closed container or pipes; and

(e) Minimizing VOC emission from cleaning of application, storage, mixing, and conveying equipment by ensuring that equipment cleaning is performed without atomizing the cleaning solvent and all spent solvent is captured in closed containers.

(2) All persons shall perform solvent cleaning operations with cleaning material having VOC content (excluding water and solvents exempt from the definition of volatile organic compounds found in R307-101-2) of 0.21 pounds per gallon or less.

(3) All sources subject to R307-350 shall maintain records demonstrating compliance with R307-350-5, R307-350-6, and R307-350-7(2).

(a) Records shall include, but not be limited to, inventory and product data sheets of all coatings and solvents subject to R307-350.

R307-350-8. Add-On Controls Systems Operations.

(1) The owner or operator shall install and maintain an incinerator, carbon adsorption, or any other add-on emission control system, provided that the emission control system is operated and maintained in accordance with the manufacturer recommendations in order to maintain at least 90% capture and control efficiency. Determination of overall capture and control efficiency shall be determined using EPA approved methods, as follows.

(a) The capture efficiency of a VOC emission control system's VOC collection device shall be determined according to EPA's "Guidelines for Determining Capture Efficiency," January 9, 1995 and 40 CFR Part 51, Appendix M, Methods 204-204F, as applicable.

(b) The control efficiency of a VOC emission control system's VOC control device shall be determined using test methods in Appendices A-1, A-6, and A-7 to 40 CFR Part 60, for measuring flow rates, total gaseous organic concentrations, or emissions of exempt compounds, as applicable.

(c) An alternative test method may be substituted for the preceding test methods after review and approval by the EPA Administrator.

(2) The owner or operator of a control system shall provide documentation that the emission control system will attain the requirements of R307-350-8(1).

(3) The owner or operator shall maintain records of key system parameters necessary to ensure compliance with R307-350-8. Key system parameters may include, but are not limited to, temperature, pressure and flow rates. Operator inspection schedule, monitoring, recordkeeping, and key parameters shall be in accordance with the manufacturer's recommendations, and as required to demonstrate operations are providing continuous emission reduction from the source during all periods that the operations cause emissions from the source.
