A.Fuel Burning Equipment Other than Reciprocating EnginesThe unit operator may elect to comply with the following work practice standards during periods of startup, shutdown, malfunction, and certain equipment maintenance in lieu of the visible emission standards in Sections 3(A)(1)(a), (1)(b), (4)(b), (5)(a), and (6); Section 3(B)(1); Section 3(D)(1); and Sections 3(E)(1) and (2). If multiple units exhaust to a common stack, the following work practice standards shall apply to all units that exhaust to the common stack.
(1) The unit operator shall maintain a log (written or electronic) of the date, time, and duration of all startups, shutdowns, malfunctions, or equipment maintenance of any unit or its associated air pollution control equipment which result in the operator electing to comply with this section. (2) The unit operator shall develop and implement a written startup and shutdown plan.(3) The duration of unit startups, shutdowns, malfunctions, or equipment maintenance shall each not exceed one hour per occurrence, unless otherwise defined and provided for in the facility's air emission license.(4) The unit, including any associated air pollution control equipment, shall be operated at all times in a manner consistent with safety and good air pollution control practices for minimizing emissions. Determination of whether such operation and maintenance procedures are being used will be based on information available to the Department that may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the unit. B.Stationary Reciprocating EnginesThe unit operator may elect to comply with the following work practice standards during periods of startup in lieu of the visible emission standards in Sections 3(A)(4)(a).
(1) The unit operator shall maintain a log (written or electronic) of the date, time, and duration of all unit startups which result in the operator electing to comply with this section.(2) The unit shall be operated in accordance with the manufacturer's emission-related operating instructions. (3) The unit operator shall minimize the engine's time spent at idle and minimize the engine's startup time to a period needed for appropriate and safe loading of the engine, not to exceed 30 minutes, after which time the non-startup emission limitations shall apply. (4) The unit, including any associated air pollution control equipment, shall be operated at all times in a manner consistent with safety and good air pollution control practices for minimizing emissions. Determination of whether such operation and maintenance procedures are being used will be based on information available to the Department that may include, but is not limited to, monitoring results, review of operation and maintenance procedures, review of operation and maintenance records, and inspection of the unit. C.Alternative Work Practice StandardsAs an alternative to the work practice standards in section 4(A) above, sources may amend their air emission license to establish specific work practice standards for startup, shutdown, malfunction, and equipment maintenance.
