§ 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.
