Cyclones are a type of Air Pollution Control Equipment (APC) that capture and separate emissions using centripetal force. Unlike baghouses, cyclones do not have fabric or filters, but rather separate large particles from small particles using a vortex force. Cyclones are often used in woodworking shops to remove dust from air, but cyclone technology can also be used to remove particles from gas or liquid media.
All Operations if they have the potential to emit 2 or more pounds per day, pursuant to Rule 201, section 122.
Woodworking operations venting a sanding process if the exhaust flow rate is greater than or equal to 750 cfm³.
Woodworking operations venting a non-sanding processes (sawing, carving, drilling, routing, etc.) vented to a cyclone require a permit if the exhaust flow rate 6,075 cfm³.
Woodworking operations venting a combined processes vented to a common cyclone require a permit if exhaust flow rate 3,400 cfm³.
For modifications of permitted equipment resulting in an increase in rating, the fee is assessed in accordance with fee schedule 1 (see Rule 301, section 308.2) based on the incremental increase in rating.
For modifications resulting in no increase in rating, the fee shall be based on Rule 301 section 306.2.
