An air quality permit, with conditions, is hereby granted to Luzenac America, Inc. Three Forks Mill
(Luzenac), pursuant to Sections 75-2-204 and 211 of the Montana Code Annotated (MCA), as amended,
and Administrative Rules of Montana (ARM) 17.8.740, et seq., as amended, for the following:

SECTION I:
Permitted Facilities

A.

Plant Location/Permitted Facility

The talc processing plant, including milling, refining, and packaging of talc, is located in
Section 36, Township 2 North, Range 1 East, Gallatin County, Montana. A complete list of
permitted equipment is included in Section I.A. of the permit analysis to this permit.

B.

Current Permit Action

On November 13, 2007, the Department of Environmental Quality (Department) received a
de minimis notification for Luzenac from Rio Tinto Minerals. The notification was for a
project involving the addition of a Jet Mill and an associated natural gas boiler and super
heater. The Jet Mill is subject to 40 CFR 60, Subpart OOO and the boiler is subject to 40
CFR 60, Subpart Dc. In addition, on December 21, 2007, the Department received
notification from Rio Tinto that the Pallet conveyor airwall had been relocated and the name
changed to the Warehouse product airwall. Permit #2282-14 was updated to reflect these
changes.

SECTION II: Conditions and Limitations

A.

Emission Control Requirements

1.

Stack emissions from each grinding mill, screening operation, bucket elevator, belt
conveyor, bagging operation, and storage bin constructed after August 31, 1983, are
limited to 0.05 grams per dry standard cubic meter (g/dscm) (0.022 grains per dry
standard cubic foot (gr/dscf)) of particulate and 7% opacity. This includes, but is not
limited to, the following equipment (40 CFR 60, Subpart OOO and ARM 17.8.340).
