				New Source Performance Standards
				42 U.S.C. Sec.

				condition.

				alternative fuel or raw material that the source is designed to accommodate. A
				source shall be considered to be designed to accommodate an alternative fuel or
				raw material if that use could be accomplished under the facility's
				construction specifications prior to the change and that use is allowed under a
				current air quality permit.
