Sec. 2. (a) Emissions of carbon monoxide shall be limited as follows: (1) Petroleum refining emissions. The source shall not operate a catalyst regeneration petroleum cracking system or a petroleum fluid coker unless the waste gas stream is burned in one (1) of the following: (A) Boiler. (B) Direct-flame afterburner. (2) Ferrous metal smelters. The source shall not operate a grey iron cupola, blast furnace, basic oxygen steel furnace, or other ferrous metal smelting equipment, having a capacity of ten (10) tons per hour or more process weight, unless the waste gas stream is burned in one (1) of the following: (A) Boiler. (B) Direct-flame afterburner. (C) Recuperative incinerator. In instances where carbon monoxide destruction is not required, carbon monoxide emissions shall be released at such elevation that the maximum ground level concentration from a single source shall not exceed twenty percent (20%) of the maximum one (1) hour Indiana ambient air quality value for carbon monoxide. (3) Refuse incineration and refuse burning equipment. The source shall not operate a refuse incinerator or refuse burning equipment unless the waste gas stream is burned in one (1) of the following: (A) Direct-flame afterburner. (B) Secondary chamber. (b) Alternatives to the carbon monoxide control methods specified in subsection (a) may only be used if submitted as an amendment to the state implementation plan (SIP) and approved by U.S. EPA.
