HYON WASTE MANAGEMENT SERVICES, INC.,

)

Petitioner,

v.

) PCB 76—166

ENVIRONMENTAL PROTECTION AGENCY,

Respondent.

CONCURRING OPINION (by Mr. Dumelle):

My reason for concurring is that no satisfactory explanation

appears in the record for the discrepancy between the stack data

submitted by Hyon and the permit limits now being requested by

Hyon.

What the Agency seems to have done in this case was to fully

incorporate into the permit those levels (and the burning rate) of

pollutants found by Hyon in its actual tests. Now Hyon has protested

the resulting permit conditions. But why were the stack tests not

performed at the burning rates testified to by Hyon as being the

minimum

for economic operation? And what would be the concentration

of pollutants in the waste gases at the higher burning rate?

We are dealing here with relatively new technology. It is

a necessary technology since many industrial wastes are best

permanently disposed of by incineration. But we must make certain

that dangerous metals or other substances are not released in

quantities so as to harm persons or the environment.
