ORDER OF THE BOARD

(by J,D,

Dumelle):

On June 10,

1983 the Board entered an Order in this

matter

proposing Rule 313 of Chapter 2:

Air Pollution which would

establish an ambient air standard for lead and the measurement

method

to be used for determining conformance

with that

standard.

Hearings were held on October 22, 1982 in Bloomington and

October 26, 1982 in Chicago to consider that proposal.

On December 27,

1982 the Illinois Environmental Protection

Agency (Agency) filed a motion to amend proposed Rule 313(b)

to allow the use

of

an alternate measurement method

in that

one

such

alternate method had already been approved by the United

States Environmental Protection Agency (USEPA).

The Agency~s

proposed language would allow any alternative methods to be

used

so long as those methods have

been approved by USEPA pursuant

to

procedures referenced in 43 Fed, Reg.

46258

as amended.

On February 18,

1983 the

Department of

Energy and Natural

Resources filed a negative

declaration with the Board

indicating

that this proposal

is of such a nature that

no

economic

impact

study is necessary to consider it,

That action was ratified

by

the Economic and Technical Advisory Committee on February 18,

1983,

Therefore, no further hearings are mandated,

The Board finds that the Agency~sproposed amendment is

meritorious

and

Measurement Method.

For determining conformance

with the ambient air quality standards for lead
