Notice of Proposed Rule
DAR File No.: 37830
Filed: 07/10/2013 09:56:56 AM
Purpose of the rule or reason for the change:
Amendments to this rule were last adopted by the Air Quality Board in December 2012. Since that time, several regulated facilities have notified the Division of Air Quality (DAQ) that they are having technical difficulties implementing the rule and requested the rule be amended. DAQ staff evaluated these comments and determined that there is merit in amending some portions of the rule.
Summary of the rule or change:
Language is added to Section R307-350-2 to clarify that the 2.7 tons VOC/year applicability applies to all miscellaneous metal product parts surface coating operations, including related cleaning activities. Exemptions are added to Section R307-350-3 for operations that are exclusively covered by Department of Defense military technical data and performed on site at installations owned or operated by the United States Armed Forces and for stripping of cured coatings and adhesives. Definitions are added to the rule and other clarifying changes are made throughout.
State statutory or constitutional authorization for this rule:
- Subsection 19-2-104(1)(a)
Anticipated cost or savings to:
the state budget:
There are no new requirements for the state; therefore, there are no costs or savings to the state budget.
There are no new requirements for local government; therefore, there are no anticipated costs or savings.
There are no new requirements for small businesses; therefore, there are no anticipated costs or savings.
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:
There are no new compliance costs for affected persons; in fact, compliance costs are mitigated for some sources, as there are two new exemptions added to the rule.
Comments by the department head on the fiscal impact the rule may have on businesses:
The fiscal impact this rule may have on some businesses is mitigated by this rulemaking as there are two new exemptions added to the rule.
