ORDER OF THE BOARD

 (by G.

 T. Girard):

On September 23,

 1994, the Board received a joint motion to

reconsider the second notice opinion and order issued on

September 15,

 1994.

 The joint motion was filed by the Illinois

Environmental Protection Agency (Agency)

 and the Illinois

Environmental Regulatory Group

 (IERG).

 The motion asked that the

Board reconsider striking the phrase “barge loading facility”

from Sections 218.920(g),

 218.940(g),

 218.960(g),

 218.980(f),

219.920(f), 219.940(f),

 219.960(f)

 and 219.980(e).

 The motion to

reconsider is granted.

The proposal, as originally filed, suggested that “barge

loading facility” be struck from those sections and the Board

retained that change at second notice.

 The Agency and IERG point

out that the Agency’s comment

 (P.C.

6)

 on this matter was

“ambiguous and led to confusion”; however, the intent of the

comment was that “barge loading facility” remain in the rule.

The motion explains that deletion of the phrase will affect

facilities which the Agency did not intend to become subject to

the control requirements.

 (Hot.

 at 2.)

 The motion also points

to comments made at hearing by the Agency and to IERG’s comment

(P.C.

5)

 in support of the retention of the phrase “barge loading

facility”.

(u.)

The Board will amend the second notice to show retention of

“barge loading facility”

 in Sections 218.920(g),

 218.940(g),

218.960(g), 218.980(f),

 219.920(f),

 219.940(f),

 219.960(f) and

219.980(e).

 The Board agrees that the record may have been

ambiguous given the testimony of IERG at the second hearing as

well as the comments filed.

 The motion now makes clear the

intent of IERG and the Agency.

 Therefore, the Board will proceed

to second notice with the retention of “barge loading facility”

in Sections 218.920(g), 218.940(g),

 218.960(g), 218.980(f),

219.920(f),

 219.940(f), 219.960(f)

 and 219.980(e).

The Board hereby amends Sections 218.920(g), 218.940(g),

218.960(g), 218.980(f),

 219.920(f),

was ever subject to the control requirements of Section

219.946 of this Part.

 No limits under this Subpart shall apply to emission

units with emissions of VON to the atmosphere less than
