KRS 224.20-142: Bases for carbon dioxide emission reduction performance standards for

existing coal-fired electric generating units.

Except for adjustments of the performance standard on a case -by-case basis under KRS

224.20-144, the performance standard that shal l be established for existing coal -fired

electric generating units shall be based on the following:

(1) The best system of emission reduction which has been adequately demonstrated for

coal-fired electric generating units subject to the performance standar d. Best system

of emission reduction shall take into account the cost of:

(a) Achieving the emission reduction;

(b) Impacting non-air-quality health and the environment; and

(c) Maintaining energy requirements needed to serve the load on the electric

generating unit;

(2) Reductions in emissions of carbon dioxide that can reasonably be achieved through

measures undertaken at each coal-fired electric generating unit; and

(3) Efficiency and other measures that can be undertaken at each coal -fired electric

generating unit to reduce its carbon dioxide emissions without doing the following:

(a) Switching from coal to other fuels;

(b) Co-firing other fuels with coal; or

(c) Limiting the utilization of the electric generating unit.
