of Environmental Protection Agency.

OPINION AND ORDER OF THE BOARD

(by Mr. Seaman):

Petitioner operates a grey iron foundry located in Rockford,

Winnebago County,

Illinois.

Petitioner requests modification

of orders by the Pollution Control Board in PCB 71-227, 71-330 a~nd

72-338, which required, inter alia,

that Petitioner obtain a

stack test on its baghouse, attached to its cupola, by an

independent testing service.

The order also required Petitioner

to file

a bond in the amount of $160,000 to ensure compliance

with the Board’s order.

Petitioner requests that the Board

waive the stack test requirement and that the bond posted by

Petitioner be returned indicating compliance with the Board

order.

Installation of the baghouse and completion of the entire

cupola emission control system was completed in December,

1972.

Mattison alleges in its petition that there is no physical

method which could be employed for testing the efficiency of the

system installed.

By definition and specific design,

the

Mattison baghouse has no stack or specific emission point.

Accordingly, it is alleged, no sample can be taken without

interferring with the operation of the system itself.

The

Mattison baghouse system is designed for particulate removal in

excess of 99.9 percent and no plume or other visible emission of

any type is produced by the system.

The Agency reports in its Recommendation that one of its

investigators observed the baghouse in operation,

that the

emissions from the baghouse were negligible, and that the baghouse

seemed to be operating efficiently.

Emissions from the cupola with and without the baghouse

as calculated by the Agency using Compilation of Air Pollutant

Emission Factors, AP—42, Table 7—10,

are as follows:

Uncontrolled

With Baghouse

Allowable

Particulates

144.5 lb/hr

1.7 lb/hr

8.7 lb/hr

The Agency further reports that testing of the baghouse

would be difficult.

It is the decision of

this Board that insistence upon the

stack test requirement in this circumstance would impose an

unnecessary hardship.

IT IS THE ORDER of the Pollution Control Board that the

stack test requirement be waived and that the bond posted be

returned to Petitioner.

I, Christan L. Moffett, Clerk of the Illinois Pollution Control

Board, certify that ~he above Opinion and Order was adopted by
