OPINION AND ORDER OF THE BOARD
(by Mr. Goodman):
Stanadyne/Chicago Division,
a division of Stanadyne,
Inc.,
(Stanadyne)
filed a
petition for variance for its facility in
Beliwood, Illinois on October
20,
1978.
The Illinois Environmen-
tal Protection Agency
(Agency)
filed its recommendation in this
matter on December 14,
1978.
No hearing was held, and the Board
has received no public comment in this case.
Stanadyne owns
and operates a facility located in
Beliwood,
Illinois which manufactures a wide range of precision metal parts
and employs between 1200 and 1300 people.
As part of its produc-
tion process, Stanadyne treats coils of hot rolled and annealed
round bar steel
stock by acid pickling with
a subsequent coating of
lime or “Gilron”,
a proprietary coating agent.
Acid pickling is
accomplished by soaking the coils
in a lO—15
sulfuric acid solu-
tion at elevated temperature.
This process removes the mill scale
and rust from the coils after which they are rinsed in water and
then soaked in either a lime or “Gilron” bath that deposits a pro-
tective and/or lubricating coat on the metal surface.
These coatings
serve to inhibit futher corosion and to facilitate subsequent cold
working.
The acid pickling tanks are served by a mechanical exhaust
system of 29,000 CFM capacity through a 42” diameter exhaust stack
leading to the building exterior.
The lime and “Gilron” solutions
are contained in tanks serviced by a mechanical exhaust fan of
17,500 CFM capacity.

Stanadyne has previously acquired an operating permit from the
Agency with an expiration date of May 11,
1978.
A 1978 application
for renewal of the operating permit by Stanadyne was denied by the
Agency which cited violations of Rules 203(a) and 204(f) (2) (B) of
Chapter
2:
Air Pollution Control Regulations
(Regulations)
as the
reason for denial.
Since Stanadyne does not consume over 1300 tons
per year of sulfuric acid, Rule
204(f) (2) (B) (i)
is applicable to the
process.
This rule limits emissions
to 0.1 lbs/hr.
for facilities
whose usage is less than 1300 tons per year.
Tests for sulfuric
acid mist emissions made at Stanadyne during 1978 indicate an aver-
age emission of 4.375 lbs./hr. from one pickling tank, with total
emissions from the operation being in excess of
8 lbs./hr.
Testing of the particulate emissions
from the lime/Gilron tank
indicated particulate emissions of 1.12 lbs./hr.
The Agency used
the lime slurry make-up of 198 lbs./hr. as the process weight rate
and calculated an emission limitation pursuant to Rule 203(a)
of
the Regulations of
0.7381 lbs./hr.
Although the Board does not
necessarily ratify the Agency’s
method of calculation with respect
to the emission of particulate matter in this case, Stanadyne does
not challenge the result,
and the record does not contain information
sufficient for the Board to make its own determination of the process
weight rate.
In any event,
Stanadyne proposes to bring the operation
into compliance with Rules
203(a)
and 204(f) (2) (B) (i) with the
installation of a wet scrubber to serve the pickling tanks and the
lime/Gilron tank.
Stanadyne includes a proposed compliance time
table as page 13 of their petition.
The proposed compliance time
table indicates
a completion date of March 31,
1979,
and envisions
compliance by April
11,
1979.
In its recommendation the Agency indicates its opinion that
the variance is warranted, but indicates that Stanadyne is about
one month behind its proposed schedule at this time.
In addition,
the Agency states
that the nearest monitor for particulates and
sulfur dioxide is
in Hillside,
Illinois, approximately
2 to
3 miles
from Stanadyne’s facility.
Although not indicative of Stanadyne’s
emissions,
results at the Hillside station were well below the
primary ambient air quality standards for both particulates and
sulfur dioxide.
Considering the hardship on Stanadyne,
should it
be forced to cease its present operation and go to a precoated
purchased stock which would necessarily have to be stored indoors,
and considering the apparent minimal environmental harm caused by
the current emissions, the Board will grant the requested variance
from May 11,
1978 until June 30, 1979 under certain conditions.
This Opinion constitutes the findings of facts and conclusions
of law of the Board
in this matter.
