Air Strippers and Soil Venting Projects

Notice of Proposed Rule

(Amendment)

RULE ANALYSIS

Purpose of the rule or reason for the change:

On 06/25/2012, the Environmental Protection Agency (EPA) proposed to conditionally approve a change to Section R307-401-15, Air Strippers and Soil Venting Projects, that was approved by the Board and submitted to EPA for review/approval in 1999. The rule contains language allowing the Director to approve alternate test and monitoring methods. However, EPA's current policy precludes approving any rule that contains language that allows a director to exercise their discretion in such cases. Therefore, they have proposed to convert the conditional approval to a disapproval in one year unless Utah revises the rule to remove the discretionary language.

Summary of the rule or change:

The proposed rule change will update the rule to refer to the most recent test methods, and will allow sources to use future updated federally approved methods, if approved by the director. DAQ is also making available for public comment a document titled, Air Quality Impact of Changes Made to Section R307-401-15 Air Strippers and Soil Venting Projects in 1999 and the new Section R307-401-16 De minimis Emissions from Soil Aeration Projects that was Adopted in 1999. This document fulfills the requirements of Section 110(l) of the Clean Air Act and justifies the changes made to Section R307-401-16 in 1999. The document will be made available at http://www.airquality.utah.gov/Public-Interest/Public-Commen-Hearings/Pubrule.htm for public review and comment from 12/01/2012 to 12/31/2012.
