OPINION AND ORDER OF THE BOARD
(by “.C. Flemal):
This matter comes before the Board on a petition for
adjusted standard filed jointly by Quantum Chemical Corporation,
USI Division (Quantum),
and the Illinois Environmental Protection
Agency
(Agency) on August 16,
1993.
The co-petitioners request
an adjusted standard from the air emission controls requirements
of parts of 35
Iii. Adm. Code 218.966 and 218.986 as these would
otherwise apply to the polymer manufacturing and cooling tower
facilities at Quantum’s plant located near Morris,
Illinois.
The Board’s responsibility in this matter arises from the
Environmental Protection Act
(Act)
(415 ILCS 5/1 et seq.).
The
Board
is charged therein to “determine,
define and implement the
environmental control standards applicable in the State of
Illinois” and to “grant
***
an adjusted standard for persons who
can justify such an adjustment”2.
More generally,
the Board’s
responsibility in this matter is based on the system of checks
and balances integral to Illinois environmental governance:
the
Board is charged with the rulemaking and principal adjudicatory
functions,
and the Illinois Environmental Protection Agency
(Agency)
is responsible for carrying out the principal
administrative duties.
Based upon the record before it and upon review of the
factors involved in the consideration of adjusted standards,
the
Board finds that the co-petitioners have demonstrated that grant
of an adjusted standard in the instant matter is warranted.
The
adjusted standard accordingly will be granted.
l
Act at Section 5(b).

Act at Section 28.1(a).
—2—
ADJUSTED STANDARD PROCEDURE
The Act at Section 28.1 provides that a petitioner may
request, and the Board may impose,
an environmental standard that
is:
(a) applicable solely to the petitioner,
and
(b) different
from the standard that would otherwise apply to the petitioner as
the consequence of the operation of a rule of general
applicability.
Such a standard is called an adjusted standard.
The general procedures that govern an adjusted standard
proceeding are found at Section 28.1 of the Act and within the
Board’s procedural rules at 35
Ill.
Adin.
Code Part 106.
Where,
as here,
the regulation of general applicability does
not specify a level of justification required for a petitioner to
qualify for an adjusted standard, the Act at Section 28.1(c)
specifies four demonstrations that must be made by a successful
petitioner:
1)
Factors relating to that petitioner are substantially
and significantly different from the factors relied
upon by the Board in adopting the general regulation
applicable to that petitioner;
2)
The existence of those factor justifies an adjusted
standard;
3)
The.requested standard will not result in
environmental or health effects substantially
and significantly more adverse than the
effects considered by the Board
in adopting
the rule of general applicability; and
4)
The adjusted standard is consistent with any
applicable federal law.
PROCEDURAL HISTORY
This matter has antecedents
in State and Federal programs
designed to reduce ozone in the lower atmosphere through the
control of volatile organic material
(VOM)
emissions.
Among
these programs has been the required application of reasonably
available control technology
(RACT) to certain VOM emission
sources.
PACT regulations developed for the Chicago ozone non—
attainment area occur at 35
Ill.
Adm. Code 218.
More general and
• less stringent regulations applicable within the ozone attainment
areas of the State occur at 35
Ill.
Adm. Code 215.
The Chicago ozone non—attainment area as originally defined
did not include any of Grundy County,
Illinois.
However,
in
response to federal requirements under the Clean Air Act
Amendments of
1990,
the Board in Docket R9l-28 redefined the
—3—
Chicago ozone non—attainment area to in~udeAux Sable Township
in Grundy County.
Quantum’s Morris Plant
is located
in Aux Sable
Township.
The effective date of the redefined non—attainment
area was November 15,
1992.
This
is the first date on which the
Part 218 regulations became applicable to the Morris Plant.
On December 7, l992~Quantum filed
its initial petition for
adjusted standard.
The Agency was not
a co-petitioner.
On
December 21,
1992 Quantum filed an amended petition,
.~hereupon
the Agency requested additional information from Quantum and
moved this Board for an extension of time to file the Agency
recommendation in response to the amended petition.
By order of
February 4,
1992 the Board granted the Agency’s request for
additional time.
On May 17,
1’~93Quantum filed a second amended petition,
again as the sole petitioner.
The Agency again requested an
extension of time for carrying on discussions with Quantw
prior
to filing of its recommendation.
The Agency’s request ~.as
granted by Board order on June 17,
1993.
A third amended petition
(Pet.)
was filed on August 16,
1993, and
is the matter before the Board today.
A principal
feature of the third amended petition is the joining of the
Agency as co-petitioner.
On August 26,
1993 the Board issued an order noting that the
two sections of the Board’s rules from which adjusted standard
was being requested were in the processes of being amended in
Board proceeding P93-94,
and asking the co-petitioners to advise
the Board as to how the amendments would affect the instant
petition.
Co-petitioners filed a response (Response)
on
September 13,
1993 indicating that the amendments do not alter
the instant pleadings except that the requested condition related
to work practices at the cooling towers
(Pet.
at p.
45-46) would
be mooted upon the adoption of 35
Ill.
Adm. Code 218.986(d);
218.986(d) has been adopted by the Board.
~ Pursuant to Section 28.1(f)
of the Act,
a petitioner who
files for an adjusted standard within 20 days of the effective
date of the applicable regulations
is exempt from the regulations
until the Board makes a final determination on the petition.
In
the instant matter that final determination
is made with today’s
order.

Final order of the Board issued September
9,
1993.
—4—
A hearing premised on the second amended petition was
originally set and noticed for June 30,
1993.
Continuance of
this hearing was granted until September 9,
1993 in the Board’s
order of June
17,
1993.
The September
9 hearing was held in
Morris,
Illinois.
No members of the public attended.
FACILITY DESCRIPTION
Quantum’s Morris Plant is located approximately six miles
east of the City of Morris.
The area
is rural and is zoned for
heavy industry.
(Pet.
at
p.
9.)
The Morris Plant is an integrated petroleum manufacturing
complex that includes manufacturing operations classified as
organic chemical manufacturing (SIC 2869)
and polymer
manufacturing
(SIC 2821).
Approximately 700 people are employed
at the plant.
(Pet.
at
p.
9.)
Quantum acquired the Morris Plant on November 5,
1986 when
it acquired the issued and outstanding capital stock of Enron
Chemical Company, owner of the plant.
Enron Chemical Company was
then renamed to USI Chemical Co.,
Inc., which was eventually
merged into Quantum’s USI Division.
(Pet.
at
p.
9.)
The instant petition is confined to VOM emission sources
related to two activities at the Morris Plant: polymer
manufacture and cooling.
In the polymer manufacturing process, plastic resins are
synthesized in closed reactor units from feed stocks of ethane,
propane, and butane
(Tr. at 16).
The resins are formed into
pellets following manufacture,
and the pellets are stored and
transferred to rail cars and trucks for distribution.
(Pet.
at
p.10.)
Co—petitioners observe that:
During the synthesis process, some of the
hydrocarbon gases are entrained within the polymer
resin.
These entrained gases are evolved during the
storage and transfer of the polymer pellets.
The
entrained gases (primarily ethylene and propylene)
are
emitted to the atmosphere with the conveying air at
numerous diverse exhaust points
(i.e.,
storage bins,
storage silos, rail car loading systems,
and truck
loading systems)
***
(Pet.
at p.
11.)
Among facilities at the Morris Plant are three at which
polymer manufacturing occurs and for which an adjusted standard
is sought:
the Low Density Polyethylene
(LDPE)
Plant,
the Linear
—5—
Low Density Polyethylene
(LLDPE)
Plant,
and the Polypropylene
Plant.
Each plant has multiple VOM emission sources.
The Morris Plant also includes six cooling towers.
Five of
these are non-contact cooling towers5 that under normal operating
conditions have no VON emissions.
Process water
is used in the
sixth tower, the ethylene oxide/ethylene glycol
(EO/EG)
cooling
tower.
In the EO/EG Plant ethylene
is reacted with oxygen to
form ethylene oxide, which in turn may be hydrated to form
ethylene glycol.
(Tr.
at 16-17.)
The EO/EG cooling tower has
VOM emissions under normal operating conditions.
RULE OF GENERAL APPLICABILITY
Co—petitioners seek alternate application of regulations
found within two sections of the Board’s PACT rules.
These are
Sections 218.966 and 218.986, which occur respectively within
subparts addressing Miscellaneous Organic Chemical Manufacturing
Processes
(35 Ill. Adm. Code:Subpart PR)
and Other Emission
Sources
(35
Ill. Adm.
•Code: Subpart TT).
The request for adjusted standard from Section 218.966 deals
sOlely with the requirements found at subsections
(a)
and
(b)6,
which require a reduction in uncontrolled VOM emissions of at
least 81 percent or an alternative control plan.
The specific
text of the two pertinent subsections
is as follows:
Section 218.966
Control Requirements
Every owner or operator of
a miscellaneous organic
chemical manufacturing process emission unit subject to
this Subpart shall comply with the requirements of
subsection
(a)
or
(b)
below.
a)
Emission capture and control techniques which
achieve an overall reduction in uncontrolled
VOM emissions of at least 81 percent from
•
each emission unit,
or
~ The non—contact cooling water towers
at
issue are the
Ethylene Plant Cooling Tower,
the LDPE Plant Cooling Tower, the
Polypropylene Plant Cooling Tower, the Utilities Cooling Tower,
and the Air Separation Plant Cooling Tower.

In Omnibus Cleanup of VOM PACT Rules
(see preceding
footnote)
the Board adopted a new subsection 218.966(c)
pertaining to leaks.
Quantum asserts that it does not need and
does not request relief from subsection
(c).
(Response at ¶3.)

(Board Note:
For the purpose of this
provision,
an emission unit is any part or
activity at a source of
a type that by itself
is subject to control requirements in other
Subparts of this Part or 40 CFR 60,

a wastewater system, or other
equipment,
or is otherwise any part or
activity at a source.)
b)
An alternative control plan which has been
approved by the Agency and the USEPA in a
federally enforceable permit or as a SIP
revision.
The request for adjusted standard from Section 218.986 deals
solely with the requirements found at subsections
(a),
(b), and
(c)7,
which require an 81 percent reduction in uncontrolled VOM
emissions,
an independent requirement for coating lines, or an
alternative control plan.
The specific text of the three
pertinent subsections is as follows:

For coating lines,
the daily-weighted average
VOM content shall not exceed 0.42 kg VON/i
(3.5 lbs VOM/gal)
of coating (minus water and
any compounds which are specifically exempted
from the definition of VOM)
as applied during
any day.
Owners and operators complying with
this Section are not required to comply with
Section 218.301 of this Part, or
C)
An alternative control plan which has been
approved by the Agency and the USEPA in a
federally enforceable permit or as a SIP
revision.
EMISSION SOURCES/COMPLIANCE EFFORTS
Quantum has undertaken various initiatives to modify its
Part 215 VON emissions program to comply with the general Part
218 regulations.
Principal focus has been on those potential
emission sources where VOM concentrations are sufficiently high
that control technologies are effective in reducing or
eliminating the emissions.
Among examples are controls on the
wax blow-down system at the LDPE Plant that are intended to
reduce VOM emissions by over 450 tons per year
(Tr. at 18), and
installation of closed loop sampling in the EO/EG Plant that is
expected to reduce VON emission by approximately 50 tons per year
(Tr.
at 20).
Quantum intends to continue these initiatives, and
they are not subject to the adjusted standard considered today.
However, there are a number of potential emissions sources
within the Quantum operation where VOM exists
in large air
streams.
These low—concentration sources are difficult to
control.
(Tr.
at 21.)
Quantum contends, and the Agency agrees,
that there are ,no technically or economically feasible control
methods for these sources beyond those currently employed.
(u.)
Co—petitioners contend, therefore, that current practices
constitute PACT.
The low—concentration emission sources at issue occur within
the finishing and storage units of the polymer plants and within
the cooling tower operations.
The former include elements of the
pneumatic conveying system, the storage silos, and the rail car
and truck loading units.
(Tr. at 21.)
The full set of low-
concentration emission sources for which adjusted standard is
requested is listed in Exhibits A and A1~ The list is today
repeated
in conditions
(A)
and
(B)
of the order accompanying
today’s action.
—8—
The largest single source among these,
accounting for 80
of
all the VON emissions at issue,
are the blender units at the LDPE
Plant.
(Tr.
at 36, 45.)
These typically emit concentrations of
ethylene at less than two hundred parts per million
(0.02)
by
weight.
(Tr.
at 36.)
However,
the air volumes are large at
approximately 70 thousand cubic feet per minute.
(a.)
Collectively, these sources are estimated to produce
emissions at the rate of 263 tons per year
(Pet.
at 13)
or 0.72
tons per day.
(Tr. at 25.)
Individual sources have emissions
based on actual field tests and measures in tons per year as

13):

Quantum observes that the particular type of polymer
manufacturing employed at its Morris Plant was not considered
during the promulgation of Part 218 or in the regulations which
preceded Part 218
(Tr. at 26), and was not reviewed by the United
States Environmental Protection Agency
(USEPA)
in preparation of
the Control Technology Guideline
(CTG)8 upon which
PACT
for the
polymer manufacturing industry was based
(Exh.
D at 5-1).
However, Quantum observes that the USEPA did review the specific
manufacturing processes employed at the Morris Plant in
developing the New Source Performance Standards
(NSPS).
The NSPS
exempt emission sources from controls where VON concentrations
are less than 0.001
(0.1)
by weight.
(Exh.
D.
at 5—2; Tr. at
22; see also 40 CFR 60.560(g).)
The emissions sources for which
•Quantum requests adjusted standard all have VOM concentrations
below 0.001
by weight.
(Tr.
at 37.)
While Quantum allows that
8
“Control of Volatile Organic Emissions From the
Manufacture of High-Density Polyethylene, Polypropylene, and
Polystyrene Resins”, EPA—450/3-83—008.
—9—
“the New Source Performance Standards are not necessarily the
same as
PACT”,
it observes that the NSPS do “give a good
indication of what kind of practical control technology is
available for these sorts of sources”.
(Tr. at 22—23.)
Moreover,
no emission control would be required for the emission
sources at issue under NSPS
if the sources were constructed
today.
(Exh.
D at 5-3.)
Quantw~has commissioned a study to review possible control
strategies and costs for the low-concentration emission sources.
The full report of this study, which considered nine possible
control technologies,
is present in the record as Exhibit D9.
Three of the possible control technologies, carbon
adsorption,
absorption, and condensation, were found to be
technically infeasible due to low adsorption capacity,
ineffective absorbants,
and condensation difficulties.
(Exh. D
at 6—26;
Tr. at ~8—39.)
The remaining six control technologies all were found to be
“economically infeasible”.
The technologies include thermal
incineration, catalytic incineration, regenerative thermal
incineration,
flaring, and use of a low pressure product
separator or degassing extruder.
For control of just the
emissions from the blenders of the LDPE Plant,
annualized costs
•range between $549,080 for the low pressure product separator to
$37,775,500 for flaring.
(Pet.
at
p.
30;
Exh.
D. at 6—2; Tr. at
39—44.)
Costs for a ton of VOM removed per year range from
$7,270 for regenerative incineration to $183,110 for flaring.
(u.)
Destruction efficiency ranges from a low of 22
for the
low pressure product separator to 98
for incineration.
(u.)
Each of the incineration technologies emits significant
amounts of NOx.
(Pet.
at p.
31.)
Since NOx also contributes to
ozone formation,
these technologies negate part of the desired
benefit.
(Exh.
D at 7-2.)
The incineration technologies also
produce carbon monoxide.
(Pet.
at p.
31.)
•
Co—petitioners contend that under normal operations there
should be no VON emissions from any of the non—contact cooling
towers.
In the case of the EO/EG cooling tower,
the VON
emissions are contended to be negligible due to the high
solubility and low vapor pressure
(less than
1 mm Hg at ambient
temperatures)
of ethylene glycol.
(Pet.
at 15.)
Co-petitioners
further observe that under normal operating conditions daily
water samples have shown ethylene oxide concentration of about
1
~ “Economic Analysis and Technology Review for Control of
VON Emissions from Polyolefin Finishing and Storage Units”,
prepared by Pilko and Associates,
Inc.
—
10
—
ppm, which corresponds to 3.4 tons per year of emissions.
(Pet.
at 16.)
HEALTH
AND
ENVIRONMENTAL
EFFECTS
Co-petitioners
contend
that
grant
of
the
requested
adjusted
standard
would
not
produce
significant
adverse
health
or
environmental effects.
Quantum observes that the major component
of its VON emissions
is ethylene’°.
(Tr. at 24.)
Although
ethylene is flammable,
it is non-toxic and is approved by the
Federal Food and Drug Administration as an indirect food additive
and for use in treating fruits and vegetables to promote
ripening.
(Pet.
at 39; Tr. at 24.)
The concentrations at which
ethylene
is emitted are far below the flammability limit.
(Pet.
at 39.)
Co—petitioners therefore expect no direct adverse health
or environmental effects from the emitted ethylene.
Ethylene does contribute to ozone formation in the lower
atmosphere and thereby does have indirect adverse health effects.
Quantum contends, however,
that its emissions are small compared
to the total VON emissions in the Chicago ozone non—attainment
area,
and hence that the emissions have no measurable impact on
the ozone levels
in the Chicago area
(Tr.
at 25) and constitute
“a negligible contribution to the VON burden” in the Chicago area
(Pet.
at
p.
38.)
PROPOSED AMENDMENT TO SECTION 218.103(b)
The Board notes that the co-petitioners also request that 35
Ill. Adm. Code 218.103(b)
be amended to specifically identify
Quantum (see Pet. at p.36 and Exh.
E).
The following amendment
is proposed:
*
*
*
b)
The provisions of the Part shall not apply to
Viskase Corporation; Allsteel,
Incorporated;
Stepan Company; e~Ford Motor Company; or quantum
Chemical Corporation to the extent such source has
obtained an adjusted standard from the Board or an
exclusion from the General Assembly for any
Subpart of this Part or of 35
Ill.
Adm. Code 215.
However, the Board cannot make this amendment in the instant
adjusted standard proceeding.
Since the amendment would change
the text of an existing regulation,
the amendment would
constitute a rulemaking,
and rulemaking must be conducted in
~ Other VON emissions are propylene and “very small amounts
of vinyl acetate, butenes, and hexenes”.
(Pet.
at
12;
Exh.
I.)
—

—
accordance with the
•egulatory procedures of Title VII of the
Act.
The Board notes that today’s grant of adjusted standard is
not dependent upon the existence of the requested amendment to
Section 218.103(b),
nor is the requested amendment necessary for
the Board to grant the adjusted standard.
CONCLUSION
Based upon its consideration of the record presented in this
action, the Board finds that the co—petitioners have provided the
justification required pursuant to Section 28.1 of the Act for an
adjusted standard to be granted with conditions.
This opinion constitutes the Board’s findings of fact and
conclusions of law in this matter.
