The definition is as follows: NR 460.02(31g)(a)(a) “Source reduction” is any practice that does both of the following: NR 460.02(31g)(a)1.1. Reduces the amount of any hazardous substance, pollutant or contaminant entering any waste stream or otherwise released into the environment, including fugitive emissions, prior to recycling, treatment or disposal. NR 460.02(31g)(a)2.2. Reduces the hazards to public health and the environment associated with the release of the substances, pollutants or contaminants. NR 460.02(31g)(b)(b) The term “source reduction” includes equipment or technology modifications, process or procedure modifications, reformulation or redesign of products, substitution of raw materials, and improvements in housekeeping, maintenance, training or inventory control. NR 460.02(31g)(c)(c) The term “source reduction” does not include any practice that alters the physical, chemical or biological characteristics or the volume of a hazardous substance, pollutant or contaminant through a process or activity which itself is not integral to and necessary for the production of a product or the providing of a service. NR 460.02(32)(32) “Reconstruction”, unless otherwise defined in a relevant standard, means the replacement of components of an affected or a previously nonaffected source to such an extent that all of the following apply: NR 460.02(32)(a)(a) The fixed capital cost of the new components exceeds 50% of the fixed capital cost that would be required to construct a comparable new MACT source.
