Nonattainment and Maintenance Areas for PM10: Fugitive Emissions and Fugitive Dust

Notice of Proposed Rule

(Amendment)

DAR File No.: 36483
Filed: 07/11/2012 05:21:53 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The Utah Air Quality Board is amending this rule in response to EPA concerns that not all anthropogenic sources of fugitive dust are being reasonably controlled as required under the Exceptional Events Rule and in order to receive EPA approval of exceptional event data flags.

Summary of the rule or change:

Rule applicability has been expanded to include PM2.5 nonattainment counties. The fugitive emissions section has been revised to clarify that EPA Method 9 is used to measure opacity, and the measurement process has also been expanded. The high wind exemption is re-written to clarify that sources must continue to operate their fugitive dust plan when winds exceed 25 mph to avoid violation of an opacity exceedance. High wind contingency measures are included under the General Requirements to enhance controls during high wind. Fugitive dust control plans must be filed using the online system before commencing activities. Suggestive control measures in Section R307-309-6 are deleted and replaced with best management practices in the online tool.

State statutory or constitutional authorization for this rule:

• Section 19-2-104
• Section 19-2-101

Anticipated cost or savings to:

the state budget:

Because the added requirements do not affect administrative procedures, there are no anticipated costs or savings to the state budget.

local governments:

Because the filing of dust controls plans and the implementation of controls are established practices, there will be minimal costs to local government.

small businesses:

The estimated cost for small businesses to implement dust control plans is $2,140 per acre.

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

The anticipated cost for any person other than small businesses, businesses, or local government entities engaged in construction projects greater than 1/4 acre is $2,140 per acre.

Compliance costs for affected persons:

The estimated cost to implement a dust control plan is $2,140 per acre.

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

The estimated cost to implement a dust control plan is $2,140 per acre.
