PROPOSED RULE.

SECOND NOTICE.

ORDER OF THE

BOARD

(by M.

Nardulli):

This matter comes before the Board on a Petition for Site—

Specific Rule Change filed on behalf of the Reilly Chemical

Corporation’s Granite City Facility.

The petition was filed with

the Board on March

8,

1988.

Presently,

the concentration of

mercury

in the wastewater discharge from the Reilly Chemical

Corporation’s Granite City facility

is governed by the effluent

standards

for mercury

in

35 Ill. Mm.

Code Section 307.1102.

Section 307.1102(a)

limits the concentration of mercury

in any

discharge

to a publicly owned,

or publicly regulated,

sewer

system to 0.0005 milligrams per liter,

subject

to the averaging

rule contained

in

35 Ill. Adm.

Code

304.104(a).

The existing

exceptions

to the standard established by Section 307.1102(a) are

laid out

in the subsequent paragraphs

of

Section 307.1102.

The

Petitioner petitions the Board

to further amend

35

Ill. Adm. Code

Section 307.1102.

On April

27, 1989,

the Board proposed the requested

rule for

Second First Notice.

The proposed rule was published

in the

Illinois Register on May 19,

1989

(Volume #13,

Issue

#20,

p.

7530).

The Board’s

rational for proposing the rule

is set

forth

in its opinion

in R88—9 of April

27,

1989.

Three public comments were received by the Board during

First Notice,

two were from the Department

of Commerce and

Community Affairs stating

that this proposed rule will have

no

effect on small business.

The other was from the Administrative

Code Division of the Secretary of State’s Office.

The

recommendations of

the Administrative Code Division have been

adopted

in the amendments

for Second Notice.

The Board finds

no

reason to otherwise

alter

its proposal.

Thus,

the Board hereby

proposes the following amendments

for

Second Notice and directs

the Clerk of the Board

to file these amendments with ~he Joint

Committee on Administrative Rules.

Section 307.1102

Mercury

a)

Except as provided below,

no person shall cause or allow

the concentration of mercury in any discharge to a

publicly owned or publicly regulated sewer system to

exceed

the following level,

subject

to the averaging

rule contained

in

35

Ill. Adm.

Code 304.104(a):

CONSTITUENT

NUMBER

mg/i

Mercury

71900

0.0005

b)

It shall

be an exception to subsection

(a)

if the

discharge

is to a publicly owned or publicly regulated

sewer system which

is

required to meet a limitation less

stringent than the 0.0005 mg/i mercury concentration

in

which case the discharge limitation shall be the

sanie

as

that

applicable

to

the

publicly

owned

or

regulated

sewer

system

to

which

it

discharges.

c)

It

shall

be

an

exception

to

subsection

(a)

if

all

the

following conditions are met:

1)

The discharger does not use mercury;

or, the

discharger

uses mercury and this use cannot be

eliminated;

or,

the discharger uses mercury only in

chemical analysis or

in laboratory or other

equipment and takes

reasonable care to avoid

contamination

of

wastewater;

and,

2)

The discharge mercury concentration

is less

than

0.003

mg/l,

as

determined

by

application

of

tne

averaging

rules

of

35

Ill.

Mm.

Code

304.104(a);

and,

3)

The discharger

is providing

the best degree of

treatment consistent with technological

101—218

feasibility, economic reasonableness and sound

engineering judgment.

This may include no

treatment

for mercury; and,

4)

The discharger has an inspection and maintenance

program likely to reduce or

to prevent an

increase

in the level of mercury discharges.

d)

The discharge of wastes from medicinal or therapeutic

use of mercury, exclusive of

laboratory use,

shall

be

exempt from the limitations of subsection

(a)

if all the

following conditions are met:

1)

The total plant discharge

is less than 227

g

(one

half pound)

as

Hg

in any year;

2)

This discharge

is

to

a public sewer

system; and

3)

The discharge does not,

alone or

in conjunction

with other sources, cause

the effluent from the

sewer system or

treatment plant to exceed 0.0005

mg/i of mercury.

e)

No person shall cause or allow any discharge of mercury

to a publicly owned or publicly regulated sewer

system

which, alone or

in combination with other sources,

causes a violation

by the sewer

treatment plant

discharge of the water quality standard of

Adm.

Code 302 for mercury applicable

in the receiving stream.

f)

For purposes of permit issuance the Agency may consider

required to assure

continued application of the exception.

When subsection

(b)

or

(c)

applies,

the Agency may

impose an effluent

limitation

in the permit which allows the discharge of

a

concentration of mercury greater than 0.0005 mg/i but

not more than 0.003 mg/i.

~j

The mercury standards

of

Section307.llO2 shall not apply

to any coal tar refinery located

in Granite City which

discharges

to any publicly—owned treatment works which

receives such a manufacturing facilities wastewater.

The amount of merc~irydischarged

by any such

manufacturing facility shall

not exceed a monthly

average of 0.025 mg/i nor

a maximum of 0.035 mg/i,

or

7.5 grams per day,

subject

to the Board’s averaging

rules

during

any

one

day.

IT

IS SO ORDERED.
