Proposed Rule. Second Notice.
OPINION AND ORDER OF THE BOARD (by J. Yi):
On November 19, 1997, W.R. Grace & Company - Connecticut (Grace) and the
Illinois Environmental Protection Agency (Agency), pursuant to Section 27 of the
Environmental Protection Act (Act) (415 ILCS 5/27 (1996)), filed a joint proposal for site
specific rulemaking. The proposal requests a site specific air regulation for Grace’s facility be
added to Subpart QQ of 35 Ill. Adm. Code 218 at Section 218.940(h). The Board adopted an
order accepting the joint proposal for hearing and granting, in part, a joint motion for
expedited review on December 4, 1997.
The Board’s responsibility in this matter arises from the Environmental Protection Act
(Act) (415 ILCS 5/1 et seq. (1996)). The Board is charged therein to “determine, define and
implement the environmental control standards applicable in the State of Illinois.” 415 ILCS
5/5(b). Today, the Board adopts the proposed amendments for second notice pursuant to the
Illinois Administrative Procedure Act (5 ILCS 100/1-1 et seq. (1996)). Excepting several non-
substantive items, the amendments adopted today are identical to those proposed for first
notice.
BACKGROUND
Grace is a Connecticut corporation in good standing registered to do business in the
State of Illinois. Grace operates a facility (facility) located at 6050 West 51st Street, Chicago,
Cook County, Illinois. This facility is operated pursuant to an air operating permit number
031821ABD. This permit was issued on September 27, 1995, by the Illinois Environmental
Protection Agency’s (Agency) Bureau of Air.
The facility manufactures solvent and water based container sealants, lubricant fluids,
and concrete additives. Pet. at 5. The joint proposal pertains solely to VOM emissions
resulting from the production of the solvent lining compound mixers (mixers) used to produce
solvent-based sealants. Pet. at 5.
REGULATORY BACKGROUND
2
In 1994, the Board promulgated certain amendments to 35 Ill. Adm. Code Part 218
that require reasonably available control technology (RACT) for sources in the Chicago ozone
nonattainment area, with the potential to emit 25 tons of VOM annually, as mandated by
Section 182 of the Clean Air Act. 42 U.S.C Section 7411a.
Emissions from Grace’s mixers occur in a complex and variable manner due to the
batch nature of the process. Thus, determining appropriate and reasonable controls for the
mixer loading activity pursuant to Subpart QQ is difficult. Pet. at 8. In 1995, the Board
granted Grace a variance regarding the emission control requirements of 35 Ill. Adm. Code
218, Subpart QQ; see W.R. Grace & Co. - Conn. v. IEPA (March 16, 1995), PCB 94-328.
This variance contained compliance dates regarding the construction, installation, and
operation of a catalytic oxidizer designed to comply with Subpart QQ’s control requirements.
Pet. at 9.
On June 14, 1996, Grace’s oxidizer exploded resulting in a fire in the solvent mixing
area of the facility. Pet. at 13. The explosion significantly damaged the oxidizer and the
associated ventilation system. Information gathered in the investigation of the explosion
suggests that no catalytic oxidizer is currently available that will control the emissions from
Grace’s mixer loading operations and that will be free from the risk of another explosion. Pet.
at 17. On February 6, 1997, the Board extended Grace’s variance until May 15, 1998. W.R.
Grace & Co. - Conn. v. IEPA (February 6, 1997), PCB 96-193.
PROCEDURAL HISTORY
The Board sent this matter to first notice under the Illinois Administrative Procedure
Act (APA) (5 ILCS 100/5-5
et seq.
(1996)) on December 18, 1997, without commenting on
the merits of the proposal. The first notice order of December 18, 1997, granted a motion to
amend the language of the proposed rule, and reflected the amendment. First notice of the
proposed rule was published at 22 Ill. Reg. 1091 (January 9, 1998).
A hearing in this matter was held on January 8, 1998, and continued on the record until
January 21, 1998. On January 21, 1998, the Board received testimony in support of the
proposed rule from Rich Irelan, Aaron Abbott, Bob Wells, and LaDonna Driver on behalf of
Grace. The Board also received testimony supporting the proposed rule from Kevin Mattison
and Yeric Yarrington of the Agency. No members of the public were present at either the
January 8, 1998, or the January 21, 1998, hearing.
On February 23, 1998, the Board received a joint comment from Grace and the Agency.
The comment sought to clarify a statement made at the January 21, 1998, hearing. The Board
also received comments on the proposal from the legislature’s Joint Committee on Administrative
Rules (JCAR).
An additional hearing was held March 30, 1998, on the single issue of the decision of the
Illinois Department of Commerce and Community Affairs (DCCA) not to conduct an Economic
Impact Study in connection with this rulemaking. No one testified at this hearing, and the Board
has not received any comments on the Economic Impact Study issue.
3
At the January 21, 1998, hearing, Mr. Irelan testified about the background of Grace’s
facility as well as Grace’s efforts to meet the requirements 35 Ill. Adm. Code 218, Subpart QQ
through the construction and installation of a catalytic oxidizer. Tr. Exh. 1-B at 3-9. Mr. Irelan
testified that, pursuant to the Agency’s recommendation, Grace filed the instant joint proposal for
site-specific rulemaking. Tr. Exh. 1-B at 13. Mr. Irelan stated that denial of the proposal would
force Grace to shut down its solvent process in Chicago, and would result in approximately 100
displaced employees.
Mr. Abbott testified on the feasibility and safety issues involved in this matter, the
technical data on the oxidizer explosion occurring at the facility, Grace’s VOM emissions, as well
as Grace’s efforts to comply with Subpart QQ. Mr. Abbott testified that the results of the
investigation into the oxidizer explosion indicate that the explosion was caused by a brief spike in
emissions resulting from solvent emitted over a one second time interval from the mixer. Tr. Exh.
1-C at 10. Mr. Abbott testified that neither Grace nor the experts brought in after the explosion,
could identify any mechanism that would detect and reliably respond to solvent emission peaks
that occur over intervals on the order of one second. Tr. Exh. 1-C at 11. Mr. Abbott further
testified that, for the purposes of the control requirements of Subpart QQ, no reasonably available
add-on control technology exists for Grace’s facility. Mr. Abbott also stated that there is no
impact to the land, water, or water supplies from the VOM emissions from Grace’s mixers. Tr.
Exh. 1-C at 16.
Mr. Wells’ testimony concerned a study prepared by one of Grace’s experts regarding the
different options available for control devices at the facility. Mr. Wells testified that the analysis
failed to identify feasible and cost-effective measures to reduce VOM emissions as required by
Subpart QQ, and that, therefore, no control is RACT. Tr. Exh. 1-D at 10.
Mr. Mattison’s testimony concerned the oxidizer explosion, and the joint efforts of the
Agency and Grace to determine whether continued operation of the oxidizer is feasible. Mr.
Mattison testified that the Agency agreed with the findings of Grace’s study that no add-on
controls under Subpart QQ were appropriate for Grace’s solvation mixers at the facility. Tr. Exh.
2-B at 2.
Mr. Yarrington testified on Grace’s current variance, and the proponents determination
that it is not possible to safely operate the Grace’s control device. Mr. Yarrington testified that
upon review of the information in this matter, no add-on control is RACT for the solvation
process at Grace. Mr. Yarrington also testified that the Agency is not opposed to the granting of
a site-specific rule change under Subpart QQ to Grace. Tr. Exh. 2-A at 2.
No substantive changes to the proposal have been requested. In response to comments
from JCAR and the Board’s internal review, the Board has made the following non-substantive
change to the first notice proposal:
•
A technical correction in the source note for Section 218.940.
4
•
A spelling correction in Section 218.940 (g).
CONCLUSION
Based upon the record, the Board finds that adoption of the proposed rule for second
notice is warranted. The Board also finds that the proposed rule will not have an adverse
economic impact on the people of the State of Illinois. See 415 ILCS 5/27 (a),(b) (1998).
ORDER
The Board hereby proposes for second notice the following amendments to 35 Ill. Adm.
Code 218. The Clerk of the Board is directed to submit this proposed rule to the Joint
Committee on Administrative Rules.
