ILLINOIS POLLUTION CONTROL BOARD

MT. CARMEL PUBLIC UTILITY 
CO.,
Petitioner,

ENVIRONMENTAL PROTECTION 
AGENCY,
Respondent.
OPINION AND ORDER OF TH~BOARD 
(by 
Mr. Goodman):
This matter comes before the Pollution Control Board
(Board) upon the Supplemental Petition of Mt. Carmel 
Public
Utility Co. (Nt~Cannel) 
to 
extend a variance from Rule 2-
2,53 
of the Rules and Regulations Governing the Control 
of
Air Pollution and from Rule 203(g) (1) (B) of the Board~s 
Air
Regulations until December 31, 1975.
On May 8, 1975, the Board issued an Interim Opinion 
and
Order in which it was found that Mt. Cannel had pursued 
its
plan of compliance in good faith 
“.   
.to normally warrant the
grant of a variance until the controls are installed, or
until an additional allocation is obtained.” However, the
Board was precluded from granting the variance beyond July 31,
1975, without a showing that the variance will not 
jeopardize
the attainment of National Ambient Air Quality Standards.
Therefore, Mt. Carmel was ordered to supply the Board with
ambient air quality data with respect to particulates.
On August 21, 1975, Mt. Cannel filed its amended petition,
herein. Said petition contains data related to the Ambient
Air Quality with respect to particulate in the Mt. Cannel
area. While no data was available from the Environmental
Protection Agency, Petitioner used information from 
Commercial
Testing and Engineering Company. According 
to this data,
based on sampling in 1970, only one test site of 
six exceeded
the geometric mean of 
75 
ugms/m3, the Primary Ambient 
Air
Quality Standard for particulate. This site was the 
Peti—
tioner~s coal pile. Since 1970, Petitioner 
has reduced the
coal it consumes by approximately 
57, The Board holds that
Mt. Carmel has shown that its area meets the National 
Primary
Ambient Air Quality Standard related 
to particulate.
Due to a change in circumstances, 
Mt. Cannel amended
its prayer for relief asking that the Board approve 
the
progress made by Petitioner ~ that it be allowed to 
continue
use of Boiler No. 4 as a coal~firedboiler until 
October 31,
1975, or until such earlier time as its 138 KV transmission
—2—
line is 
tie&-in to the CIPS at Albion,  at which time Boiler
No. 4 will be 
retired  
from service,
It 
seems 
that Boiler No. I was taken out of service in
July. 1975, 
due 
to corrosion of both lower headers.  
When
the healer is 
returned to service, a new 
dust 
collector,  new
induced draft 
fan and necessary duct work will have been
compLeted and 
it will meet the particulate  emission regula-
tions of 
the 
Board.
Tue 
construction of Mt. Carrae1~s138 
KU 
transmission
line was completed 
to the Albion substation on July 28,
~973, 
However, CIPS would not tie-in the line until the
peak 
season 
was over. Mt. Carmel believes that this will
occur no 
later than October 31, 1975.
The 
Board 
approves of the progress Petitioner has made
and 
will 
grant the requested variance.
Tnas 
Opinion constitutes the findings of fact and
conclusions 
of law of the Board in this matter.
ORDER
::t 
is 
the Order of 
the Pollution Control Board that Mt.
Carmel 
Public 
Utility

Regulations Governing 
the 
Control of Air
Pollution  and 
Rule 203(g) (1) (B) of the Air Regulations for
its No. 4  boiler until 
October 31, 1975, 
or until  
the 138 KV
interconnection line 
with Central 
Illinois Public 
Service
Company at Albion, Illinois, 
is completed, whichever shall
farat occur.
