This action proposes amendments in addition to those proposed on November 25, 2011, and April 15, 2013, for the Mineral Wool Production and Wool Fiberglass Manufacturing source categories. This action addresses comments received on previous proposals, explains changes to previously proposed limits for sources in these industries and clarifies our use of the upper prediction limit (UPL) in setting MACT floors. The Environmental Protection Agency (EPA) is taking comments on only aspects of the proposed rules that are discussed in this document. When finalized, these proposed standards would increase the level of environmental protection.
