OPINION AND ORDER OF THE BOARD (by Dr. Odell)

Joslyn Mfg. and Supply Company filed its Petition for

Variance seeking relief from Rule 203(b) (particulates) of the

Air Pollution Control Regulations for a period of one year

pending installation of control equipment. The record shows

that Petitioner~s operation has never been in compliance; therefore,

pursuant to Rule 203(c), the applicable Rule in this case is

Rule 203(a)

Petitioner operates a zinc galvanizing facility in Franklin

Park, Illinois. After the steel or iron which is to be galvanized

has been degreased, pickled and rinsed it is fluxed in zinc

ammonium chloride and then immersed in a bath of molten zinc.

This plant operates on a three-shift, 6 days per week basis to

produce 8400 lbs,/hr. of galvanized metal. About 670 lbs./hr,

of zinc are used in this operation.

Presently the plant is operating with one 4~~ 8” x 52~

galvanizing kettle. Emissions from this kettle are now vented

directly to the atmosphere at the rate of 22.26 lbs./hr. The

allowable rate under Rule 203(a) is 1.34 lbs./hr. Particulates

emitted from the plant are composed of:

A second galvanizing kettle will he added during 1975.

Emissions from the two kettles will be controlled by installing

enclosures around the kettles and venting the fumes to a bag house.

The project is currently in the engineering design phase. Current

data indicate that the control equipment will cost about $200,000

and, together with the second kettle, will take one year to com-

plete.

Petitioner explains that part of this time is required to

formulate procedures to insure satisfactory operation of the hag

house. Since amrnonium chloride fumes tend to absorb moisture, dry

powdered lime will have to be injected into the gas stream at the

bag house inlet. The bags will also have to be precoated with dry

lime to facilitate periodic cleaning. Petitioner states that the

process has been used successfully at other locations,

Petitioner claims that it could not come into immediate com-

pliance without shutdown of the facility. Such closure would im-

pose an arbitrary and unreasonable hardship on Petitioner, its

employees and customers. Most employees would have difficulty in

finding other employment, Petitioner states that the proposed

control equipment could not be installed immediately regardless of

cost. It is claimed that no harm would be imposed upon the public

from the continued operation of the plant because ammonium chloride

is a non-toxic dust and is not known to be harmful or injurious in

any way. This facility is located in an industrial area with no

residences nearby. The Agency has not received any complaints from

area citizens about this facility.

The Agency believes the one year project completion schedule

is reasonable and recommends granting this variance subject to

certain conditions, The Board agrees that Petitioner appears to

finally be on the road to achieving compliance.

Compliance with Rule 203(a) was required by December 31, 1973.

Petitioner did not submit any evidence to justify this delay of al-

most one year before requesting the variance or seeking to achieve

compliance. Because of this unexplained delay, the Board will not

grant a variance for the full term sought by Petitioner. The

Board grants Petitioner a variance until June 30, 1975.
