|(a) Except as provided under §116.1510(b), (c), or (d) of this title (relating to Applicability and Exemption Requirements), each best available retrofit technology (BART)-eligible source shall conduct an analysis of emissions control alternatives for all visibility-impairing pollutants. This analysis must include the identification of all available, technically feasible retrofit technologies, and for each technology identified, an analysis of the cost of compliance, the energy and non-air quality environmental impacts, the degree of visibility improvement in affected Class I areas resulting from the use of the control technology, the remaining useful life of the source, and any existing control technology present at the source. Based on this analysis, the owner or operator shall identify an emission control strategy as the prospective BART control strategy for the source. The determination of BART must be made according to 40 Code of Federal Regulations Part 51, Appendix Y, as effective September 6, 2005. (b) As part of the BART analysis required in subsection (a) of this section, the owner or operator shall include detailed information documenting the projected hourly and annual emission limits for the selected BART control strategy. (c) The owner or operator of each BART-eligible source shall submit a completed BART analysis to the commission's Air Permits Division under seal of a Texas licensed professional engineer. The completed BART analysis must be received by the commission's Air Permits Division no later than April 30, 2007.
