Before December 10, 1993, the following facilities at U.S. Steel-Gary Works shall have a continuous emission monitor for opacity installed and operating: (1) Coke battery underfire stacks at U.S. Steel-Gary Works. (2) Numbers 2 and 3 precarbon building preheating and drying line exhaust gas precipitators (six (6) units). One (1) opacity continuous emission monitor shall be installed before December 10, 1993. The remaining five (5) opacity continuous emission monitors shall be installed before December 31, 1994. Based on an evaluation of the technical feasibility of operation of the first monitor on one (1) line, U.S. Steel-Gary Works may petition for a: (A) one (1) year extension of the requirement to install the remaining five (5) monitors; or (B) waiver for installation and operation of the six (6) opacity continuous emission monitors. U.S. Steel-Gary Works shall include information on the moisture content of the gases and their effect on accurate opacity measurements as part of any such petition.
