ORDER OF THE BOARD (by A.S. Moore):
On December 20, 2007, the Illinois Environmental Protection Agency (Agency) filed a
“Motion to Proceed with Amended Proposal and Withdraw Testimony” (Mot.). The Agency
states that “the basis and scope of this [amended] regulatory proposal is significantly narrower
with the adoption of R07-18 and the limited geographic applicability.” Mot. at 4. Specifically,
the Agency moves that the hearing officer proceed to schedule hearings on the amended proposal
and that previously-submitted testimony be withdrawn from the record. On January 3, 2008, the
Illinois Environmental Regulatory Group (IERG) filed its response. The Board today grants the
Agency’s motion and directs the hearing officer to proceed to hearing on the amended proposal.
The Board also grants the Agency’s motion to withdraw testimony.
Below, the Board provides an abbreviated procedural history before providing a brief
summary of the amended proposal and the motion to withdraw testimony. After summarizing
IERG’s response, the Board addresses the Agency’s motion and reaches its conclusion.
ABBREVIATED PROCEDURAL HISTORY
On April 6, 2007, the Agency filed a rulemaking proposal intended to reduce emissions
of nitrogen oxides (NO
x
) from stationary reciprocating engines and turbines, which the Board
docketed as R07-18. In an order dated May 17, 2007, the Board concluded that the Agency’s
entire proposal was not “required to be adopted” by the Clean Air Act (CAA) under Section 28.5
of the Environmental Protection Act (Act). 415 ILCS 5/28.5 (2006). Accordingly, the Board
bifurcated the proposal by continuing to consider, in docket R07-18, only the portion applicable
to the 28 internal combustion engines affected by the NOx State Implementation Plan (SIP) Call
Phase II under Section 28.5 “fast-track” procedures. The Board directed the publication of the
remainder of the Agency’s proposal for first notice under the general rulemaking provisions of
Sections 27 and 28 of the Act (415 ILCS 5/27, 28 (2006)) in docket R07-19 without commenting
on the merits of the proposal. The Board adopted final rules in R07-18 on September 20, 2007.

Reg. 14254-71 (Oct. 12, 2007).

On June 15, 2007, the hearing officer issued an order in R07-19 scheduling a first hearing
beginning September 18, 2007 in Springfield with prefiled testimony due to be filed by August
27, 2007, and prefiled questions based on that testimony due to be filed by September 10, 2007.
The same order scheduled a second hearing beginning November 5, 2007 in Chicago with
prefiled testimony due to be filed by October 15, 2007, and prefiled questions based on that
testimony due to be filed by October 29, 2007.
On August 23, 2007, the Agency filed a motion to cancel the scheduled hearings and
associated prefiling deadline. In an order dated August 27, 2007, the hearing officer granted the
motion. At the direction of the hearing officer, the Agency has since filed two status reports, a
first on October 31, 2007, and a second, on November 19, 2007, which indicated that the Agency
would file an amended proposal with the Board before the end of December 2007.
On December 20, 2007, the Agency filed its “Motion to Proceed with Amended Proposal
and Withdraw Testimony.” On January 3, 2008, IERG filed its response (Resp.).
SUMMARY OF AMENDED PROPOSAL
The Agency states that proceeding with the amended proposal will partly satisfy Illinois’
obligation to meet the CAA’s requirement under the 8-hour National Ambient Air Quality
Standard (NAAQS) for NO
x
reasonably available control technology (RACT) and would
improve air quality by reducing precursors for fine particulate matter (PM
2.5
). Mot. at 1.
Specifically, the Agency proposes to control NO
x
emissions from engines and turbines at 100 ton
per year sources, or RACT units located either in the greater Chicago or Metro-East/St. Louis
nonattainment areas, based on the originally proposed capacity thresholds.
Id
. The Agency
states that its amended proposal differs from the original proposal in six ways. Mot. at 3.
The Agency states that it is not filing an amended Statement of Reasons with its amended
proposal. However, the Agency has submitted an amended Technical Support Document (TSD).
In addition, the Agency lists five issues and requests that, where those issues are discussed in the
Statement of Reasons in a manner that differs from the amended TSD, “the facts in the amended
TSD should be the facts relied upon.” Mot. at 3.
MOTION TO WITHDRAW TESTIMONY
The Agency “requests that all the testimony submitted in support of the original proposal
(R07-18) on May 11, 2007, and subsequently included by the Board on the docket for this
rulemaking, be withdrawn as the basis and scope of this regulatory proposal is significantly
narrower with the adoption of R07-18 and the limited geographic applicability.” Mot. at 4. In
addition, the Agency requests that the hearing officer and participants hold a conference call in
order to establish hearing dates for the amended proposal.
IERG RESPONSE
In its response, IERG expresses agreement with the Agency’s request that the hearing
officer and participants hold a conference call in order to establish hearing dates and prefiling
3
deadlines for the amended proposal. Resp. at 1. IERG requests that it participate in that call.
Id
.
IERG’s response did not address the Agency’s motion to withdraw testimony.
See
Resp.
The Board has received no other response to the Agency’s motion.
CONCLUSION
The Board first grants the Agency’s motion to proceed with the amended proposal and
directs the assigned hearing officer to proceed under the rulemaking provisions of the Act and
the Board’s procedural rules.
See
415 ILCS 5/27, 28 (2006); 35 Ill. Adm. Code 102. As the
Board on May 17, 2007, sent a proposal to first notice in this docket (31 Ill. Reg. 7702 (June 8,
2007)), the Board will determine in the course of this proceeding whether to file a second
proposal for first notice.
See
5 ILCS 100/5-40(e) (one-year deadline).
The Board also grants the Agency’s motion to withdraw testimony submitted in support
of the original proposal on May 11, 2007, and subsequently incorporated into the record of this
proceeding. The Board directs the Clerk to withdraw the specified testimony from the record of
this proceeding.
IT IS SO ORDERED.
I, John T. Therriault, Assistant Clerk of the Illinois Pollution Control Board, certify that
the Board adopted the above order on January 10, 2008, by a vote of 4-0.
