Oil and Gas Industry: Flares

Change in Proposed Rule

DAR File No.: 38581
Filed: 10/07/2014 12:15:40 PM

RULE ANALYSIS

Purpose of the rule or reason for the change:

The Utah Air Quality Board proposed this new rule, R307-503, for public comment on 06/04/2014. A 30-day public comment period was held, during which the Division of Air Quality (DAQ) received comments that resulted in changes being made to the originally proposed rule. The comments received asked for certain terms to be defined and raised concerns regarding the cost to install an auto-ignitor on an open flare. Retrofits were limited to enclosed flares in response to this comment.

Summary of the rule or change:

Definitions for "enclosed flare", "flare", and "open flare" are added to the rule. The rule is also modified to require retrofits only on enclosed flares. The applicability date for all new flares has been changed to 01/01/2015 to reflect the expected effective date of this rule. (DAR NOTE: The original proposed new rule upon which this change in proposed rule (CPR) was based was published in the July 1, 2014, issue of the Utah State Bulletin, on page 42. Underlining in the rule below indicates text that has been added since the publication of the proposed new rule mentioned above; strike-out indicates text that has been deleted. You must view the CPR and the proposed new rule 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:

The changes made to this rule do not apply to the state; therefore, there are no anticipated costs or savings to the state budget.

local governments:

The changes made to this rule do not apply to local government; therefore, there are no anticipated costs or savings.

small businesses:

In the original notice of proposed rule published in the Bulletin on July 1, 2014, DAQ stated that the rule does not apply to small businesses and therefore there were no anticipated costs or savings. That statement was incorrect as there are many oil and natural gas producers in Utah that the rule applies to. Colorado estimated a cost of $2,348 to retrofit an existing flare with an auto igniter, with an annualized cost of $475. The overall cost effectiveness of the retrofit was $302/ton of VOC reduced. Because the change in proposed rule removes the requirement to retrofit existing open flares, there will be a savings; however, it is difficult to determine how many open flares will now no longer be required to be retrofitted.

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

The changes to this rule do not apply to persons other than small businesses, businesses, or local government entities; therefore, there are no anticipated costs or savings.

Compliance costs for affected persons:

This change results in a reduction of compliance costs for affected persons because it removes the requirement to retrofit existing open flares. The number of open flares that will no longer need to be retrofitted is unknown, so the reduction in compliance costs is unknown.

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

This change results in a reduction of compliance costs for affected persons because it removes the requirement to retrofit existing open flares. The number of open flares that will no longer need to be retrofitted is unknown, so the reduction in compliance costs is unknown.
