Machining, grinding and sanding equipment emit air contaminants including particulate matter and toxic air contaminants. This equipment requires a permit from the District unless it is exempt according to District Rule 11.
The most common type of machining, grinding and sanding equipment permitted by the District includes processing of fiberglass or other material that contains toxic air contaminants. Often this is conducted within a booth or room and emissions are controlled by venting air with entrained particulate through a filter or other dust collection device.
