COMPANY (E.D. EDWARDS ) (Site-Specific

GENERATING STATION) FOR A ) Rulemaking – Air)

SITE-SPECIFIC AIR REGULATION: )

35 ILL. ADM. CODE 214.561 )

Proposed Rule. Second Notice.

OPINION AND ORDER OF THE BOARD (by T.E. Johnson):

This matter comes before the Board upon a proposal for site-specific rulemaking filed by

Central Illinois Light Company (E.D. Edwards Generating Station) (CILCO) pursuant to Section

27 of the Illinois Environmental Protection Act (Act). 415 ILCS 5/27 (2000). CILCO operates

the E.D. Edwards Generating Station (facility) located near Peoria in Peoria County.

Specifically, CILCO requests a site-specific sulfur dioxide emissions limit for Boiler #2 at its

facility. A hearing in this matter was held on October 11, 2002.

By today’s action the Board adopts the proposed rule for second notice, pursuant to the

Illinois Administrative Procedure Act (5 ILCS 100/1-1). No comments were received during

first notice, and the proposal adopted here is substantively unchanged from that adopted in the

Board’s January 23, 2003 first-notice and opinion order. The following opinion will explain the

proposal background, summarize the first-notice proposal, and discuss the economic

reasonableness and technical feasibility of the rule.

BACKGROUND

CILCO’s facility consists of three coal-fired boilers. CILCO received a variance from 35

Ill. Adm. Code 214.141 in a Board order issued on April 15, 1999.

See

Central Illinois Light

Company v. IEPA, PCB 99-80 (Apr. 15, 1999). The variance is effective through July 31, 2003.

Boilers 1 and 3 are subject to a sulfur dioxide emission limit under a site-specific rule at 35 Ill.

Adm. Code 214.561. Boiler 2 is subject to sulfur dioxide (SO2) emissions limit under 35 Ill.

Adm. Code 214.141.

CILCO seeks to make permanent the relief it was granted in PCB 99-80 by amending 35

Ill. Adm. Code 214.561 with respect to the requirements for the operation of Boiler 2. CILCO

requests that the Board repeal the text of 35 Ill. Adm. Code 214.561 and replace it verbatim with

text from the variance order of April 15, 1999.

See

CILCO, PCB 99-80 slip op. at 8-9. The

Board has previously incorporated by reference the record of PCB 99-80.

Specifically, CILCO requests that Section 214.561 read as follows:

Sulfur dioxide emissions from Boiler Nos. 1, 2, and 3 at the Edwards Station may not

exceed the limits listed below. CILCO must determine compliance with these limits on a

daily basis using the sulfur dioxide methodology of the Phase II Acid Rain Program set

forth in 40 C.F.R. Part 75.

a. The average sulfur dioxide emissions from Boiler Nos. 1, 2,and 3, as a

group may not exceed 4.71 pounds per million British thermal units

(lb/mmBtu) of actual heat input;

b. The average sulfur dioxide emissions from any one boiler may not exceed

6.6 lb/mmBtu of actual heat input; and

c. Sulfur dioxide emissions for all three boilers, as a group, may not exceed

34,613 pounds per hour, on a 24-hour average basis.

PROCEDURAL HISTORY

On February 28, 2002, CILCO filed a petition for an adjusted standard pursuant to

Section 28.1 of the Environmental Protection Act (Act) 415 ILCS 5/28.1 (2000). On March 21,

2002, the Board issued an order reserving judgment on the acceptance of this case until CILCO

addressed whether or not the relief requested by CILCO is contrary to the Act and the

Administrative Procedures Act, (5 ILCS 100/1-1

et seq

. (2000)) in that CILCO is requesting the

amendment of a rule in an adjusted standard proceeding.

On April 26, 2002, CILCO filed a motion to file an amended pleading and a proposal for

site-specific rulemaking. In the motion, CILCO requests that the Board accept the proposal for

site-specific rulemaking as an amendment to the February 28, 2002 filing. CILCO represents

that the Illinois Environmental Protection Agency (Agency) was apprised of the motion and had

no objection.

On May 2, 2002, the Board closed the docket in AS02-4 and opened regulatory docket

R02-21. The Board found that the proposal for rulemaking met the requirements of 35 Ill. Adm.

Code 102.210 and accepted it for hearing.

A hearing in this matter was held on October 11, 2002, at 202 N.E. Madison in Peoria.

Both CILCO and the Agency appeared and presented testimony at the hearing. The testimony

offered by the parties was summarized in the Board’s January 23, 2003 first-notice opinion and

order. No members of the public attended the hearing. The only public comment after the

hearing was filed by CILCO.

In its first-notice opinion and order, the Board found that adoption of CILCO’s proposed

site-specific rule for the purposes of first notice was warranted. The Board found that CILCO

presented information indicating that compliance with 35 Ill. Adm. Code 214.141 is not

economically reasonable or technically feasible. The Board further found that CILCO

presented

evidence regarding the nature of existing air quality and consistency with federal regulations.

The first notice publication of the rules appeared in 27

Illinois Register

2578 (February

14, 2003). No public comments were received during the 45-day first notice period. The Joint

Committee on Administrative Review (JCAR) filed non-substantive comments addressing

grammar and format changes.

DISCUSSION

At first notice, the Board found that compliance with 35 Ill. Adm. Code 214.141 was not

economically reasonable or technically feasible. The Board has received no additional

comments discussing economic reasonableness and technical feasibility of the proposed rule. On

August 14, 2002, pursuant to Section 27(b) of the Act (415 ILCS 5/27(b) (2000)), the Board

requested that the Department of Commerce and Community Affairs (DCCA) conduct an

economic impact study on the proposed rule. The request letter referenced a letter, dated March

10, 2000, from DCCA. The March 10, 2000 letter informed the Board that DCCA would not be

doing economic impact studies. At the October 11, 2002 hearing the Board made available

copies of the DCCA letter and the Board's March 12, 2002 letter. The Board received no

comments on the letter.

As noted, the Board did receive non-substantive comments from JCAR. The Board has

incorporated the suggested changes into the proposal as issued for second-notice review.

CONCLUSION

Based on the record developed to date in this matter, the Board finds that adoption of

CILCO’s proposed site-specific rule is warranted. The Board proposes this rulemaking for

second-notice review by JCAR.

ORDER

The Board directs the Clerk to cause the filing of the following with the Joint Committee

on Administrative Rules for its second-notice review.
