AUTHORITY: Implementing Section 39(a) of the Environmental Protection Act (Ill. Rev. Stat. 1983, ch. 111½, par. 1039(a)) and authorized by Section 4 of the Environmental Protection Act (Ill. Rev. Stat. 1983, ch. 111½, par. 1004).
SOURCE: Filed and effective December 29, 1977; codified at 8 Ill. Reg. 17882.
Section 266.100 Introduction
Particulate emission standards and limitations for new process emission sources are contained in 35 Ill. Adm. Code 212.321 and for sources existing as of April 14, 1972 at 35 Ill. Adm. Code 212.322. To determine whether source emissions exceed the allowable emission rates under either of these sections, the process weight rate must be known.
Section 266.105 Definition of Process Weight Rate
Process weight rate is defined at 35 Ill. Adm. Code 211.122 as follows:
The actual weight or engineering approximation thereof of all materials except liquid and gaseous fuels and combustion air, introduced into any process per hour. For a cyclical or batch operation, the process weight rate shall be determined by dividing such actual weight or engineering approximation thereof by the number of hours of operation excluding any time during which the equipment is idle. For continuous processes, the process weight rate shall be determined by dividing such actual weight or engineering approximation thereof by the number of hours in one complete operation, excluding any time during which the equipment is idle.
