INTERIM

ORDER

OF THE BOARD (by J. Anderson):

On March 24, 1980, the Village of Lemont petitioned for vari-

ance from the 15 pCi/l gross alpha particle activity maximum limit

contained in Rule 304(c) of Chapter 6: Public Water Supply. The

90—day decision period was waived. The original Recommendation of

the Agency, filed May 9, 1980, supporting grant of variance, lists

test results from various dates in 1979. Hearing was held

May

16,

1980, at which citizen objectors were heard.

In light of the Agency’s admission in City of Minonk, PCB 80—

136, October 2, 1980, pp.1—2, that the Agency’s radiological test-

ing methodology had an “accuracy problem”, the Board must assume,

unless informed otherwise, that the test results included with the

petition cannot be relied upon. Unreliable results cannot support

the grant of the variance requested, as it is possible that accurate

tests will show that no variance is needed.

If an amended petition containing gross alpha particle activity

test results dated on or after August 22, 1980 is not submitted to

the Board within 45 days of the date of this Order, this petition

will be subject to dismissal.

IT IS SO ORDERED.

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

Board, hereby cer ify that the above Interim Order ~as adopted on
