Section 19-0909. Interim control target

1. a. In the absence of a controlling federal statute or program which
  the commissioner determines is consistent with the purpose and intent of
  this  title,  the  department  shall  promulgate,  no later than January
  first, nineteen hundred eighty-six, an interim control  target  for  the
  control  of sulfate deposition at each sensitive receptor area where the
  environmental threshold value is exceeded,  and  rules  and  regulations
  necessary to implement such targets.
    b.  Any  such  interim  control  target  promulgated  pursuant to this
  section  shall  take  effect  on   January   first,   nineteen   hundred
  eighty-eight,  and  all  facilities  and  stationary sources shall be in
  compliance with the interim control target by such date.
    c. In connection with the promulgation of an interim  control  target,
  the  department  shall prepare an analysis of the economic impact of the
  implementation of such target.
    2. The department shall not require or prohibit any particular control
  technique to achieve any such interim control target,  but  shall  allow
  the  use  of  any  or  all  reasonable  sulfur  dioxide emission control
  techniques, including but not limited to:
    a. The substitution of lower sulfur content fossil fuels.
    b. One or more combinations of blending various sulfur content  fossil
  fuels.
    c. The precombustion cleaning of coal.
    d.  The  conversion  or modification of an existing boiler to a boiler
  capable of burning a lower-sulfur content coal.
    e. The use of  best  available  control  technology  at  the  time  of
  construction, reconstruction or substantial addition to or alteration of
  a facility or stationary source.
    f. The installation of flue gas desulfurization equipment.
    g. The installation of fluidized bed boilers.
    h.  For  persons operating multiple boilers, the coordinated operation
  of these boilers to minimize the discharge of sulfur dioxide from them.
    i. The use of least emissions dispatch.
    j. The decommissioning of a facility or stationary source.
    k. The purchasing of electricity or steam from another person,  so  as
  to  lessen  the  operation  of a facility or stationary source, provided
  such purchase does not contribute to a net increase in  acid  deposition
  in sensitive receptor areas.
    l.  The  implementation  of energy conservation measures to lessen the
  amount of operation of a facility or stationary source.
