On page 2 of SB 1591, add a new subsection (f) to read as
follows:
      (f)  Any facility that emits air pollutants that was in
existence on or before September 1, 1971 and is operating without a
construction permit issued by the commission is not eligible for
the type of exemption which the commission is authorized to grant
under Subsection (a) of this section unless the proposed
alternative method of pollution control will result in a decrease
in actual air emissions from that facility.
