RULE ANALYSIS

Purpose of the rule or reason for the change:

On 03/25/2015, Governor Gary Herbert signed Utah H.B. 229, Air Quality Modifications, from the 2015 General Session into law. H.B. 229 revised the statutory definitions of several terms in Section 19-2-102. The purpose of this rule is to amend the Utah Air Quality Rules so that they reflect the changes made to Section 19-2-102.

Summary of the rule or change:

The word "contaminant(s)" was replaced with "pollutant(s)" throughout the rule.

State statutory or constitutional authorization for this rule:

• Section 19-2-104

Anticipated cost or savings to:

the state budget:

Replacing "contaminants" with "pollutants" will not create additional obligations for regulated entities. There are no anticipated costs or savings to the state budget.

local governments:

Replacing "contaminants" with "pollutants" will not create additional obligations for regulated entities. There are no anticipated costs or savings to local governments.

small businesses:

Replacing "contaminants" with "pollutants" will not create additional obligations for regulated entities. There are no anticipated costs or savings to small businesses.

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

Replacing "contaminants" with "pollutants" will not create additional obligations for regulated entities. There are no anticipated costs or savings to other persons.

Compliance costs for affected persons:

Replacing "contaminants" with "pollutants" will not create additional obligations for regulated entities. There are no compliance costs for affected persons.

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

Replacing "contaminants" with "pollutants" will not create additional obligations for regulated entities. Therefore, the amendments will have no fiscal impact on businesses.

R307. Environmental Quality, Air Quality.

R307-206. Emission Standards: Abrasive Blasting.

R307-206-1. Purpose.

R307-206 establishes work practice and emission standards for abrasive blasting operations for sources located statewide except for those sources listed in section IX, Part H of the state implementation plan or located in a PM10 nonattainment or maintenance area.

 

R307-206-2. Definitions.

(1) The following additional definitions apply to R307-206:

"Abrasive Blasting" means the operation of cleaning or preparing a surface by forcibly propelling a stream of abrasive material against the surface.

"Abrasive Blasting Equipment" means any equipment utilized in abrasive blasting operations.

"Confined Blasting" means any abrasive blasting conducted in an enclosure which significantly restricts air [contaminants]pollutants from being emitted to the ambient atmosphere, including but not limited to shrouds, tanks, drydocks, buildings and structures.

"Multiple Nozzles" means a group of two or more nozzles being used for abrasive cleaning of the same surface in such close proximity that their separate plumes are indistinguishable.

"Unconfined Blasting" means any abrasive blasting which is not confined blasting as defined above.

 

R307-206-3. Applicability.

R307-206 applies statewide to any abrasive blasting operation, except for any source that is listed in Section IX, Part H of the state implementation plan or that is located in a PM10 nonattainment or maintenance area.

 

R307-206-4. Visible Emission Standards.

Visible emissions from abrasive blasting operations shall not exceed 40% opacity, except for an aggregate period of three minutes in any one hour.

 

R307-206-5. Visible Emission Evaluation Techniques.

(1) Visible emissions shall be measured using EPA Method 9. Visible emissions from intermittent sources shall use procedures similar to Method 9, but the requirement for observations to be made at 15 second intervals over a six-minute period shall not apply.

(2) Visible emissions from unconfined blasting shall be measured at the densest point of the emission after a major portion of the spent abrasive has fallen out, at a point not less than five feet nor more than twenty-five feet from the impact surface from any single abrasive blasting nozzle.

(3) An unconfined blasting operation that uses multiple nozzles shall be considered a single source unless it can be demonstrated by the owner or operator that each nozzle, measured separately, meets the emission and performance standards provided in R307-206-2 through 4.

(4) Visible emissions from confined blasting shall be measured at the densest point after the air [contaminant]pollutant leaves the enclosure.
