40 CFR 61.147 - Standard for fabricating.
(a)Applicability. This section applies to the following fabricating operations using commercial asbestos:
(1) The fabrication of cement building products.
(2) The fabrication of friction products, except those operations that primarily install asbestos friction materials on motor vehicles.
(3) The fabrication of cement or silicate board for ventilation hoods; ovens; electrical panels; laboratory furniture, bulkheads, partitions, and ceilings for marine construction; and flow control devices for the molten metal industry.
(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 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 Administrator, and revise as necessary, a written maintenance plan to include, at a minimum, the following:
(i) Maintenance schedule.
(ii) Recordkeeping plan.
(5) Maintain records of the results of visible emission monitoring and air cleaning device inspections using a format similar to that shown in Figures 1 and 2 and include the following:
(i) Date and time of each inspection.
(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.
(v) Brief description of corrective actions taken, including date and time.
(vi) Daily hours of operation for each air cleaning device.
(7) Retain a copy of all monitoring and inspection records for at least 2 years.
(8) Submit semiannually a copy of the visible emission monitoring records to the Administrator if visible emission occurred during the report period. Semiannual reports shall be postmarked by the 30th day following the end of the six-month period.
