Rule R307-309

Nonattainment and Maintenance Areas for PM10 and PM2.5: Fugitive Emissions and Fugitive Dust

Change in Proposed Rule

DAR File No.: 36483
Filed: 11/08/2012 01:32:02 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

During the public comment period and public hearing, many comments were submitted. As a result of the Division of Air Quality's (DAQ) analysis and response to comments, much of the original proposed rule was changed.

Summary of the rule or change:

The rule applicability was changed to be only those areas within PM10 and PM2.5 nonattainment and maintenance areas. The rule was changed to state that dust control plans submitted before 12/03/2012 will have met the filing requirement. The compliance schedule for newly regulated areas was extended to 90 days for Sections R307-309-10 and R307-309-11; all other sections retain the 30-day compliance schedule. Subsection R307-309-6(2) was changed to clarify what the approval process is for fugitive dust control plans. The rule was amended to allow the director to approve an alternate measure for pre-event contingencies for high wind events. A record keeping requirement was added to the rule. The rule is changed to clarify that a new fugitive dust plan is required when sources make modifications. These changes also add clarification that a plan must be accepted and not merely submitted. The exemption in Section R307-309-3 was revised to exempt all agricultural activities to be consistent with the exemption in the 1992 EPA-approved version of the rule. (DAR NOTE: This change in proposed rule has been filed to make additional changes to a proposed amendment that was published in the August 1, 2012, issue of the Utah State Bulletin, on page 14. 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 change in proposed rule 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:

• Section 19-2-104
• Section 19-2-101
• Section 19-2-109

Anticipated cost or savings to:

the state budget:

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

local governments:

There will be costs associated with the new record keeping requirement of the rule, but those costs should be minimal. By limiting the applicability of the rule to only PM2.5 and PM10 nonattainment and maintenance areas, fewer local governments will be required to implement dust control plans. This results in a savings of approximately $2,140 per disturbed acre for those to which the rule no longer is applicable.

small businesses:

By limiting the applicability of the rule to only PM2.5 and PM10 nonattainment and maintenance areas, fewer small businesses will be required to implement dust control plans. This results in a savings of approximately $2,140 per disturbed acre for those small businesses to which the rule no longer is applicable. For those to whom the rule still applies there will be added costs for the new rulemaking requirement; however, those costs should be minimal.

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

By limiting the applicability of the rule to only PM2.5 and PM10 nonattainment and maintenance areas, fewer persons other than small businesses, businesses, or local government entities will be required to implement dust control plans. This results in a savings of approximately $2,140 per disturbed acre for those to which the rule no longer is applicable. For those to whom the rule still applies there will be added costs for the new rulemaking requirement; however, those costs should be minimal.

Compliance costs for affected persons:

The new record keeping requirement will result in added compliance costs for affected persons; however, those costs should be minimal.

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

By limiting the applicability of the rule to only PM2.5 and PM10 nonattainment and maintenance areas, fewer businesses will be required to implement dust control plans. This results in a savings of approximately $2,140 per disturbed acre for those small businesses to which the rule no longer is applicable. For those to whom the rule still applies there will be added costs for the new rulemaking requirement; however, those costs should be minimal.
