RSA 125-C:10-b Best Available Control Technology Required.

I. For the purposes of this section:
(a) "Best available control technology" means an emission limitation based on the maximum degree of reduction for each air contaminant that would be emitted from any device that the department, on a case-by-case basis, taking into account energy, environmental, public health, and economic impacts and other costs, determines is achievable for such device through application of production processes or available equipment, methods, systems, and techniques, including fuel cleaning or treatment or innovative fuel combustion techniques for control of such air contaminant.
(b) "Exempt fuel" means coal, natural gas, landfill gas, digester or bio gas, untreated wood, virgin petroleum products, biodiesel, as defined by RSA 362-A:1-a, I-b, or an
