ILLINOIS ENVIRONMENTAL

PROTECTION AGENCY,

Respondent.

ORDER OF THE BOARD

(by

 1. Anderson):

This petition, filed April 19,

 1985,

 requests variance from

the

 5 pCi/i

 combined radium standard of

35

 Ill. Adm. Code

604.301(a).

As

 the petition waives hearing and appears

 to provide

adequate information

 in support of the request,

 the petition will

be forwarded to the Agency

for

 its Recommendation.

The Board notes,

 however, that

 in its experience

 a community

in violation of

the

 radium standard

 is often

 in Violation of

the

15 pCi/i

 gross alpha particle activity limitation of

35

 Iii. Adm.

Code 604.301(a);

 the monitoring

 for radium is triggered by

exceedance of the gross

 alpha standard pursuant

 to Section

605.106.

 In the event

 that such

 is the case,

 the City would

be

advised to make

 an early amendment to

 its petition (accompanied

by monitoring data)

 requesting relief from the gross

 alpha

standard,

 so as

 to allow the Board

 to consider

 in one proceeding

all parameters

 for which

 the City may need variance

 to continue

operation of

 its water

 supply.

IT

 IS SO ORDERED.
