Each owner or operator of any of the fabricating operations to which this rule applies shall either:
(2) Use the methods specified by Rule 361.152 to clean emissions containing particulate asbestos material before they escape to, or are vented to, the outside air.
(3) Monitor each potential source of asbestos emissions from any part of the fabricating facility, including air cleaning devices, process equipment, and buildings that house equipment for material processing and handling, at least once each day, during daylight hours, for visible emissions to the outside air during periods of operation. The monitoring shall be by visual observation of at least 15 seconds duration per source of emissions.
(4) Inspect each air cleaning device at least once each week for proper operation and for changes that signal the potential for malfunctions, including, to the the maximum extent possible without dismantling other than opening the device, the presence of tears, holes, and abrasions in filter bags and for dust deposits on the clean side of bags. For air cleaning devices that cannot be inspected on a weekly basis according to this paragraph, submit to the Control Officer, and revise as necessary, a written maintenance plan to include, at a minimum, the following:
(ii) Recordkeeping plan.
(ii) Presence or absence of visible emissions.
(iii) Condition of fabric filters, including presence of any tears, holes and abrasions.
(iv) Presence of dust deposits on clean side of fabric filters.

(vi) Daily hours of operation for each air cleaning device.
(7) Retain a copy of all monitoring and inspection records for at least two years.
