APPENDIX A Rule into Section Table
AUTHORITY: Implementing Section 39(a) and of the Environmental Protection Act (Ill. Rev. Stat. 1983, ch. 111 1/2, par. 1039(a))and authorized by Section 4 of the Environmental Protection Act (Ill. Rev. Stat. 1983, ch. 111 1/2, par. and 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.
| Section 266.110 | ||
| Allowable Emission Rate for Small Operations | ||
For process weight rates of less than 100 pounds per hour (45.35 kg/hr), the allowable emissions rate is 0.55 pounds per hour (0.25 kg/hr).
| Section 266.115 | ||
| Process Weight Rate for Surface Preparation and Finishing Operations | ||
The substrate is not included in calculating the process weight rate for any surface operation.
| a) | ||
| The process weight rate for painting operations is calculated by using the weight of the paint and solvent used. | ||
| b) | ||
| The process weight rate for hot or cold dip operations is calculated by using the weight of the material desposited or of the make-up material added to the bath. | ||
| c) | ||
| The process weight rate for plating operations is calculated by using the weight of the material added to the bath, including solvents. If the solvent is water, the water is included in the weight. | ||
| d) | ||
| The process weight rate for lubricating operations is calculated by using the weight of the lubricating material. | ||
| e) | ||
| The process weight rate for degreasing operations is calculated by using the weight of the degreasing material added to the bath. | ||
| f) | ||
| The process weight rate for nail galvanizing by the tumbling method is caluclated by using the weight of zinc powder and flux added to the nails. | ||
| Section 266.120 | ||
| Process Weight Rate for Conveying Operations | ||
Items of equipment used to classify or to separate materials in conveying operations are considered emission sources, not control equipment.
| a) | ||
| The process weight rate for conveying operations using fluid conveyors is calculated by using the weight of material being conveyed; water, air or other transport media is not included. | ||
| b) | ||
| The process weight rate for conveying operations using belts, screws, etc., is calculated by using the weight of the material being conveyed. | ||
| Section 266.125 | ||
| Process Weight Rate for Heating or Heat Treating | ||
The process weight rate for heating or heat treating is calculated by using the weight of the material to be heated or treated.
| Section 266.130 | ||
| Process Weight Rate for Smokehouses | ||
The process weight rate for smokehouses is calculated by using the weight of the material burned or of the liquid smoke used.
| Section 266.135 | ||
| Process Weight Rate for Catalytic Reactions, Calcining, or Other Chemical Operations | ||
The process weight rate for catalytic reactions, calcining, or other chemical operations is caluclated by using the weight of the material added to the process. The oxygen, which chemically combines (theoretically), is allowed.
| Section 266.140 | ||
| Process Weight Rate for Fluxing | ||
The process weight rate for fluxing is calculated by using the weight of the flux used or the make-up flux added to the bath.
| Section 266.145 | ||
| Process Weight Rate for Inoculation, Demagging, Degassing | ||
The process weight rate for inoculation, demagging, degassing and related operations is calculated by using the weight of the material added to the bath.
| Section 266.150 | ||
| Process Weight Rate for Stripping Operations | ||
| a) | ||
| The process weight rate for chemical stripping operations is calculated by using the weight of the material stripped plus the weight of the chemicals added to the bath or expended during the operation. | ||
| b) | ||
| The process weight rate for salt stripping operations is calculated by using the weight of the material stripped plus the salts added to the bath. | ||
| Section 266.155 | ||
| Process Weight Rate for Shakeout Operations | ||
The process weight rate for shakeout operations is calculated by using the weight of the sand and other materials freed from the casting.
| Section 266.160 | ||
| Process Weight Rate for Drying Operations | ||
The process weight rate for drying operations is calculated by using the weight of the material to be dried, as weighed entering the dryer.
| Section 266.165 | ||
| Process Weight Rate for Concrete Batch Plants | ||
The process weight rate for concrete batch plants is calculated by using the weight of the cement, aggregate and water as added at the batch plant.
| Section 266.170 | ||
| Process Weight Rate for Cement Silos | ||
The process weight rate for cement silos is calculated by using the weight of the maximum amount of cement transferred in any one-hour period.
| Section 266.175 | ||
| Process Weight Rate for Arc Welding | ||
The process weight rate for arc welding is calculated by using the weight of the welding rod and flux consumed.
| Section 266.180 | ||
| Process Weight Rate for Quenching | ||
The process weight rate for quenching is calculated by using the weight of the quench material added to the bath.
| Section 266.185 | ||
| Process Weight Rate for Scarfing Operations | ||
The process weight rate for scarfing operations is calculated by using the weight of all material removed by scarfing.
| Section 266.190 | ||
| Operations to Which Process Weight Rate Rule Does Not Apply | ||
| a) | ||
| The process weight rate rule does not apply to pickling operations. The applicable sulfuric acid mist regulations shall be used to determine allowable particulate emissions. | ||
| b) | ||
| The process weight rate rule does not apply to thermal stripping operations. The applicable incinerator regulations shall be used to determine allowable particulate emissions. | ||
| c) | ||
| The process weight rate rule does not apply to thermal wire reclaiming. The applicable incinerator regulations shall be used to determine allowable particulate emissions. | ||
