 FIRST NOTICE.

OPINION

AND ORDER

OF THE BOARD

 (by E. Dunham):

On June 15,

 1994, the Illinois Environmental Protection

Agency (Agency) filed this proposal for rule making.

 Section

182(b) (1)

of the Clean Air Act

 (42 USC 7511(b) (1)) requires all

moderate and above ozone nonattaininent areas to achieve a 15

reduction in

1990 emissions of volatile organic material

 (VON) by

1996.

 The Chicago and the Metro-East

St.

Louis areas are

classified as severe and moderate nonattainment areas for ozone

and are subject to the 15

 reduction requirement.

 The proposed

rule represents Part III of the rules proposed in the Agency’s

15

 Rate of Progress Plan (ROP Plan).

 Section 182(b)

(1)

requires

states to submit 15

 ROP Plans within three years of the

enactment of the CAA.

 Illinois submitted its plan on November

15,

 1993.

 On January 21,

 1994, the USEPA found the submitted

plan to be incomplete because

it

was not accompanied by fully

adopted rules.

 Illinois is currently on notice that

it

has 18

months to adopt the necessary rules before sanctions are imposed

under Section 179(a)

 of the

CAA

 (42 USC §7509(a)).

The Board’s responsibility in this matter arises from the

Environmental Protection Act (Act).

(4i~ILCS

5/1 et

seq.

(1992).)

 The Board is charged by the ~

 to “determine,

 define,

and implement the environmental controi _tandards applicable in

the state of Illinois.”

 (415 ILCS 5/5(b)

 (1992).)

 More

generally, the Board’s rule making charge is based on the system

of checks and balances integral to the Illinois environmental

system:

 the Board has responsibility for the rulemaking and

principal adjudicatory functions, while the Agency is responsible

for carrying out the principal administrative duties.

The

Agency’s duties include administering the regulations that are

proposed for adoption in this rulemaking.

This proposal was filed pursuant to Section 28.5 of the

Environmental Protection Act (Act).

 (415

ILCS5/28.5

 (1992).)

Pursuant

 to the provisions of that section the Board is required

to proceed within the set time frames toward the adoption of the

regulation.

 The Board has no discretion to adjust these time

frames under any circumstances.

 Today the Board acts to send

this proposal to first notice under the Illinois Administrative

Procedure Act without commenting

on

the merits of the proposal.

The following schedule indicates the deadlines by which the Board

must act as provided in Section 28.5.

First Notice

 on or before June 29,

1994

First Hearing

 on or before August 9,

1994

Second

Hearing

before

September

1994

Third

Hearing

Second

Notice

(if 3rd hearing cancelled)

 on or before October 21,

1994

(if 3rd hearing held)

 on or before November

10,

1994

Final Adoption or Filing

 21 days after receipt of JCAR

certification of no objection

The Board notes that the above dates are the deadlines as

 established by Section 28.5 and do not represent actual hearing

dates or filing dates.

While

 the schedule includes a second and

third hearing, these hearings may be cancelled if unnecessary.

The Board will proceed in this matter as prescribed in Section

28.5 and discussed in the Board’s resolution.

 (See RES 92—2

(October 29,

 1992 and December 3,

 1992).)

The Agency has filed a “Motion for Waiver of Certain

Requirements” with the proposal.

 The Agency requests waiver of

the following requirements: that the Agency submit the original

and nine copies of the original and nine copies of the entire

regulatory proposal, that the Agency submit an entire copy of the

proposal to the Attorney General and the Department of Energy and

Natural Resources

(DENR),

 and that the Agency submit copies of

all documents on which it relied.

 The Agency requests that it be

permitted to file an original plus five complete copies of the

proposal and four partial copies.

 A partial copy does not

include the supporting exhibits.

 The Attorney General and DENR

have agreed with the Agency that a complete copy of the proposal

need not be served on them.

 The Agency has provided the Board

with one copy of some of the documents on which it relied and

notes that the other documents are readily accessible or already

in the Board’s possession.

 The Board grants the Agency’s motion.

In the interest of administrative economy, the Board directs

 the hearing officer to verify that persons on the notice list in

this proceeding wish to continue to receive mailings in this

proceeding.

ORDER

The Board directs the Clerk to cause publication of the

following amendments

 in the Illinois Register for first notice1:

For mailing purposes, the Board has omitted from the

order those portions of the tables of contents, amounting to

almost 20 pages, that are not proposed to be changed in this

RACT implementation:

a)

 Determination of VOM destruction efficiency for evaluating

compliance with the 98 weight percent VON reduction or 20

ppmv emission limit specified in Sections 215.520 219.520

through 215.527 219.527 of this Part and

b)

 Determination of offgas flowrate, hourly emissions and

stream net heating value for calculating TRE.

All reference methods identified in this Appendix refer to the

reference methods specified at 40 CFR 60, Appendix A,

incorporated by reference in Section 215.105 219.112 of this

Part.

VON DESTRUCTION EFFICIENCY DETERMINATION

The following reference methods and procedures are required for

determining compliance with the percent destruction efficiency

specified in Sections 215.520 219.520 through 215.527 219.527 of

this Part.

a)

 Reference Method

 1 or 1A for selection of the sampling site.

The control device inlet sampling site for determination of

vent stream molar composition or total organic compound

destruction efficiency shall be prior to the inlet of any

control device and after all recovery devices.

b)

 Reference Methods

2,

 2A, 2C or 2D for dete~.r!~inationof the

volumetric flowrate.

c)

 Reference Method

 3 to measure oxygen concentration of the

air dilution correction.

 The emission sample shall be

corrected to

 3 percent oxygen.

49

d)

 Reference Method 25

 (a) to determine the concentration of

total organic compounds (minus methane and ethane)

 in the

control device outlet and total organic compound reduction

efficiency of the control device.

TRE DETERMINATION

The following reference methods and procedures are required for

determining the offgas flowrate, hourly emissions, and the net

heating value of the gas combusted to calculate the vent stream

TRE.

a)

 Reference Method 1 or 1A for selection of the sampling site.

The sampling site for the vent stream flowrate and molar

composition determination prescribed in

 (b) and

(c)

 shall be

prior to the inlet of any combustion device, prior to any

post-reactor dilution of the stream with air and prior to

 any post-reactor introduction of halogenated compounds into

the vent stream.

 Subject to the preceding restrictions on

the sampling site,

 it shall be after the final recovery

device.

 If any gas stream other than the air oxidation vent

stream is normally conducted through the recovery system of

the affected facility, such stream shall be rerouted or

turned off while the vent stream is sampled, but shall be

routed normally prior to the measuring of the initial value

of the monitored parameters for determining compliance with

the recommended RACT.

 If the air oxidation vent stream is

normally routed through any equipment which is not a part of

the air oxidation process as defined in 35 Ill. Adm. Code

211.122 211.350 of this Part,

 such equipment shall be

bypassed by the vent stream while the vent stream is

sampled, but shall not be bypassed during the measurement of

the initial value of the monitored parameters for

determining compliance with Subpart V.

b)

 The molar composition of the vent stream shall be determined

using the following methods:

1)

 Reference Method 18 to measure the concentration of all

organics, including those containing halogens, unless a

significant portion of the compounds of interest are

polymeric (high molecular weight), can polymerize

before analysis or have low vapor pressures,

 in which

case Reference Method 25(a)

 shall be used.

2)

 ASTM D1946-67

 (reapproved 1977),

 incorporated by

reference in Section 215.105 219.112 of this Part, to

measure the concentration of carbon monoxide and

hydrogen.

3)

 Reference Method

 4 to measure the content of water

vapor,

 if necessary.

50

c)

 The volumetric flowrate shall be determined using Reference

Method

 2, 2A,

 2C or 2D,

 as appropriate.

1)

 The net heating value of the vent stream shall be calculated

using the following equation:

n

H=K

E

 CiHi

i=1

Where:

H

 Net heating value of the sample, NJ/scm, where the

net enthalpy per mole of offgas is based on

combustion at 25°Cand 760 mm Hg, but the standard

temperature for determining the volume

corresponding to one mole is 20°C,as in tfle

definition of F

 (vent stream flowrate) below.

K

 Constant,

 1.740 x 10~(1/ppm)

 (mole/scm)

 (MJ/kcal)

where standard temperature for mole/scm is 20°C.

Ci

 Concentration of sample component i, reported on a

wet basis,

 in ppm, as measured by Reference Method

18 or ASTM D1946—67

 (reapproved 1977),

incorporated by reference in Section 215.105

219.112 of this Part.

Hi

 Net heat of combustion of sample component i,

kcal/mole based on combustion at 25°Cand 760 mm

Hg.

 If published values are not available or

cannot be calculated, the heats of combustion of

vent stream components are required to be

determined using ASTM D2382-76,

 incorporated by

reference in Section 215.105 219.112 of this Part.

e)

 The emission rate of total organic compounds in the process

vent stream shall be calculated using the following

equation:

n

E=K

F

E

 CiMi

i=l

Where:

E

 Emission rate of total organic compounds (minus

methane and ethane)

 in the sample in kg/hr;

K

 Constant 2.494 x 1O~(1/ppm)

 (mole/scm)

 (kg/g)

(min/hr), where standard temperature for

(mole/scm)

 is 20°C;

Mi

 Molecular weight of sample component i

 (g/mole);

51

F

 Vent stream flowrate (scm/mm), at a standard

temperature of 20°C.

f)

 The total vent stream concentration (by volume) of compounds

containing halogens (ppmv, by compound) shall be summed from

the individual concentrations of compounds containing

halogens which were measured by Reference Method 18.
