                                 A BILL TO BE ENTITLED
                                        AN ACT
    1-1  relating to the modification of an existing facility under the
    1-2  Texas Clean Air Act.
    1-3        BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF TEXAS:
    1-4        SECTION 1.  Subdivision (9), Section 382.003, Health and
    1-5  Safety Code, is amended to read as follows:
    1-6              (9)  "Modification of existing facility" means any
    1-7  physical change in, or change in the method of operation of, a
    1-8  facility <stationary source> in a manner that increases the amount
    1-9  of any air contaminant <pollutant> emitted by the facility <source>
   1-10  into the atmosphere or that results in the emission of any air
   1-11  contaminant <pollutant> not previously emitted.  The term does not
   1-12  include:
   1-13                    (A)  insignificant increases in the amount of any
   1-14  air contaminant <pollutant> emitted that is authorized by one or
   1-15  more board exemptions;
   1-16                    (B)  insignificant increases at a permitted
   1-17  facility;
   1-18                    (C)  maintenance or replacement of equipment
   1-19  components that do not increase or tend to increase the amount or
   1-20  change the characteristics of the air contaminants emitted into the
   1-21  atmosphere; <or>
   1-22                    (D)  an increase in the annual hours of operation
   1-23  unless the existing facility has received a preconstruction permit
   1-24  or has been exempted, pursuant to Section 382.057, from
    2-1  preconstruction permit requirements;
    2-2                    (E)  a physical change in, or change in the
    2-3  method of operation of, a facility that does not result in a net
    2-4  increase in allowable emissions of any air contaminant and that
    2-5  does not result in the emission of any air contaminant not
    2-6  previously emitted, provided that the facility:
    2-7                          (i)  has received a preconstruction permit
    2-8  or has been exempted pursuant to Section 382.057 from
    2-9  preconstruction permit requirements no earlier than 120 months
   2-10  before the change will occur; or
   2-11                          (ii)  uses, regardless of whether the
   2-12  facility has received a permit, an air pollution control method
   2-13  that is at least as effective as the best available control
   2-14  technology, considering technical practicability and economic
   2-15  reasonableness, that the board required or would have required for
   2-16  a facility of the same class or type as a condition of issuing a
   2-17  permit or permit amendment 120 months before the change will occur;
   2-18                    (F)  a physical change in, or change in the
   2-19  method of operation of, a facility where the change is within the
   2-20  scope of a flexible permit; or
   2-21                    (G)  a change in the method of operation of a
   2-22  natural gas processing, treating, or compression facility connected
   2-23  to or part of a natural gas gathering or transmission pipeline
   2-24  which does not result in an annual emission rate of a pollutant in
   2-25  excess of the volume emitted at the maximum designed capacity,
   2-26  provided that the facility is one for which:
   2-27                          (i)  construction or operation started on
    3-1  or before September 1, 1971, and at which either no modification
    3-2  has occurred after September 1, 1971, or at which modifications
    3-3  have occurred only pursuant to standard exemptions; or
    3-4                          (ii)  construction started after
    3-5  September 1, 1971, and before March 1, 1972, and which registered
    3-6  in accordance with Section 382.060 as that section existed prior to
    3-7  September 1, 1991.
    3-8        SECTION 2.  Section 382.0512, Health and Safety Code, is
    3-9  amended to read as follows:
   3-10        Sec. 382.0512.  MODIFICATION OF EXISTING FACILITY.
   3-11  (a)  Except as provided in Subsection (b), in <In> determining
   3-12  whether a proposed change at an existing facility is a
   3-13  modification, the board may not consider the effect on emissions
   3-14  of:
   3-15              (1)  any air pollution control method applied to a
   3-16  source; or
   3-17              (2)  any decreases in emissions from other sources.
   3-18        (b)  In determining whether a proposed change at an existing
   3-19  facility results in a net increase in allowable emissions under
   3-20  Section 382.003(9)(E), the board shall consider the effect on
   3-21  emissions of:
   3-22              (1)  any air pollution control method applied to the
   3-23  facility;
   3-24              (2)  any decreases in allowable emissions from other
   3-25  facilities that have received a preconstruction permit no earlier
   3-26  than 120 months before the change will occur; and
   3-27              (3)  any decreases in actual emissions from other
    4-1  facilities that meet the criteria of Section 382.003(9)(E)(i) or
    4-2  (ii).
    4-3        (c)  Nothing in this section shall be construed to limit the
    4-4  application of other state or federal requirements, nor shall this
    4-5  limit the board's authority under Subchapter D.
    4-6        SECTION 3.  Section 382.0518, Health and Safety Code, is
    4-7  amended by adding Subsection (h) to read as follows:
    4-8        (h)  A reference to a permit in this section includes an
    4-9  amendment to a permit.
   4-10        SECTION 4.  This Act takes effect September 1, 1995.
   4-11        SECTION 5.  The importance of this legislation and the
   4-12  crowded condition of the calendars in both houses create an
   4-13  emergency and an imperative public necessity that the
   4-14  constitutional rule requiring bills to be read on three several
   4-15  days in each house be suspended, and this rule is hereby suspended.
