SUPPLEMENTAL STATEMENT

(by Mr. Dumelle):

The suspended particulate levels quoted by Mr. William

Dallas for the moni~oron his home are quite high

(R.

99)

.

The

reading of

753 ug/m

and other values of 420 and 442 ug/m3 he

reported exceed the Illinois and United States air quality standard

of 260 ug/m3

(for a 24—hour period)

by

190,

62,

and 70

res-

pectively.

We do not know,

on this record, whether air quality standards

will be met everywhere even after the expenditure of the $17,500,000

control program.

The control program proposed ought to go forward

with the utmost speed to achieve maximum relief for all of Granite

City.

But after completion, the area of the Dallas instrument

location especially should be checked to determine

if it is

in

conformance with the air quality standards.

Air quality standards

still govern even

if specific Board emission regulations are met.
