PART 61_NATIONAL EMISSION STANDARDS FOR HAZARDOUS AIR POLLUTANTS
--Table of Contents
 
            Subpart M_National Emission Standard for Asbestos
 
Sec. 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.
    (b) Standard. Each owner or operator of any of the fabricating 
operations to which this section applies shall either:
    (1) Discharge no visible emissions to the outside air from any of 
the operations or from any building or structure in which they are 
conducted or from any other fugitive sources; or
    (2) Use the methods specified by Sec. 61.152 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 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.
    (6) Furnish upon request and make available at the affected facility 
during normal business hours for inspection by the Administrator, all 
records required under this section.
    (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.
