This action approves the State Implementation Plan (SIP) revision to 30 TAC Chapter 101, Section 101.2(b) concerning Multiple Air Contaminant Sources. The SIP revision was submitted by the Governor to EPA on January 10, 1996. The revision to the rule eliminates the 50,000 population limitation and is now applicable statewide to all counties regardless of population. The revision also limits the use of the provision to a property under the control of a single entity which has been or will be divided and placed under the control of separate entities, creating a new property line configuration for properties operated, or intended to be operated, as an integrated plant or plants where individual facilities are owned by separate entities, but all facilities are under the control of a single entity. The approval of these Texas SIP revisions make the revisions federally enforceable.
