The provisions o this subpart are ap- hc&ble to those sources specified in Bl.22. S 61.21 Definitions. Terms used in this subpart are defined In the act, in subpart A of this part, or in this section as follows: (a) "Asbestos" means actinolite. amosite, anthophyliile, chrysotilc, crocidolite, tremolite. (b) "Asbestos material" means as bestos or any material containing as bestos. (c) "Particulate asbestos material" means finely divided panicles of asbestos material. id) "Asbestos tailings" means any solid waste product of asbestos mining or milling operations which contains as bestos. <e> "Outside air" means the air out side buildings and structures. if) "Visible emissions" means any emissions which arc visually detectable without the aid of instruments and which contain particulate asbestos material. 61.22 Emission standard. la) Asbestos mills: There shall be no visible emissions to the outside air from any asbestos mill except as provided in paragraph If) of this section. Outside storage of asbestos materials is not con sidered a part of an asbestos mill. <b) Roadways: The surfacing of road ways with asbestos tailings is prohibited, except for temporary roadways on an of asbestos ore deposits. The deposl- Cof asbestos tailings on roadways covwith snow or ice is considered "sur facing.'' <c> Manufacturing: There shall be no visible emissions to the outside air, ex cept as provided hi paragraph If') of this section, from any building or struc ture in which *he following operations are conducted or directly from any of the following operations if they are con ducted outside of buildings or structures. (1) The manufacture of cloth, cord, wicks, tubing, tape, twine, rope, thread, yarn, roving, lap, or other textile ma terials. i2) The manufacture of cement prod ucts. (3) The manufacture of fireproofing and insulating materials. (4) The manufacture of friction products. 15) The manufacture of paper, mill board. and felt. ' (6) The manufacture of floor tile. 17) The manufacture of paints, coat ings. caulks, adhesives, sealants. 18) The manufacture of plastics and rubber materials. 19) The manufacture of chlorine. <d> Demolition: Any owner or opera tor of a demolition operation who intends to demolish any institutional, commer cial, or Industrial building (including apartment buildings having more than four dwelling units), structure, facility, installation, or portion thereof which contains any boiler, pipe, or load-sup porting structural member that is insu lated or fireproofed wuh friable asbestos material shall comply with the require ments set forth in this paragraph. (1) Notice of intention to demolish shall be provided to the Administrator at least 20 days prior to commencement of such demolition or anytime prior to commencement of demolition subject to paragraph id) (4) of this section. Such notice shall include the following information: (ii Name of owner cr operator. (ii) Address of owner or operator. in) Description of the building, struc ture, facility, or installation to be de molished, liv) Address or location of the build ing, structure, facility or installation. (v) Scheduled starting and completion dates of demolition. ui) Method of demolition to be em ployed. (vii) Procedures to be employed to meet the requirements ol this paragraph. O Tne lol owing procedures shall be used to prevent emissions of particulate asbestos material to outside air: (1) Friable asbestos materials, used to insulate or fireproof any boiler, pipe, or load-supporting structural member, shall be wetted and removed from any build ing, structure, facility, or installation subject to this paragraph before wreck ing of load-supporting structural mem bers Is commenced. The friable asbestos debris shall be wetted adequately to in sure that such debris remains wet during all stages of demolition and related han dling operations. Ill) No pipe or load-supporting struc tural member that is covered with fri able asbestos Insulating or fireproofing material shall be dropped or thrown to the ground from any building, structure, facility, or installation subject to this paragraph, but shall be carefully low ered or taken to ground level. (ill) No friable asbestos debris shall be dropped or thrown to the ground from any building, structure, facility, or in stallation subject to this paragraph or from any floor to any floor below. For buildings, structures, facilities, or in stallations. 50 feet or greater in height, friable asbestos debris shall be trans ported to the ground via dust-tight chutes or containers, (3) Sources subject to this paragraph are exempt from the requirements of }{ 61.05(a). 61.07, and 61.09. (4) Any owner or operator of a demoli tion operation who intends to demolish a building, structure, facility, or installa tion to which tne provisions of this para graph would be applicable but which has been declared by proper St.ve or local authority to be structurally unsound and which is in danger of imminent collapse is exempt from the requirements of this paragraph other than the reporting re quirements specified by paragraph id) (1) of this section and the wet'mg of friable asbestos debris as spccn.ed oy paragraph (d> (3) (i) of this section. (e) Spraying: There shall be no *. :s;ble emissions to the outside air from the spray-on application of materials con taining more than 1 percent nsoestos. on a dry weight basis, used to insulate or fireproof equipment and machinerv ex cept as provided in paragraph 1 f' of this section. Spray-on materials u ed to insu late or fireproof buildings, structures, pipes, and conduits shall contain less than 1 percent asbestos on a Jry we,ght basis. (1) Sources subject to this paragraph are exempt from the requuemenrs of 61.05<a), 61.07. and 3 61.09. (2) Any owner or operator w ho intends to spray asbestos materials to insulate or fireproof buildings, structures, ru^cs. con duits, equipment, and inach.i.cty shall report such intention to the acmm.jtra- tor at least 20 days prior to the com mencement of the spraying operation. Such report shall include tne following information: pp OffTOn (i) Name of own*Jk0PM JU (ii) Address of owiTer or operator. (ill) Location of spraving operation, (iv) Procedures to be followed to meet the requirements of this par .graph. (f) Rather than meet the ruble- emission requirements of pa'. . r.-.pns a), (c). and (c) of this section. wr."r or operator may elect to use t..; r v mods specified by 5 61.23 to clean cm ...,:ons containing particulate asbeif :m'.-trial before such emissions escape to, or are vented to, the outside air.  61.23 Air-clcaning. If air-clqanlng is elected, as permit ted by S 6122(f). the requirements of this section must be met. (a) Fabric Alter collection devices must be used, except as noted in para graphs (b) and (c) of this section. Such devices must be operated at a pressure drop of no more than 4 inches water gage, as measured across the filter fabric. The airflow permeability, as determined by ASTM method D737-69, must not exceed 30 ft'/min/ft1 for woven fabrics or 35 ft"/min/ft: for felted fabrics, except that 40 ft'/min/ft* for woven and 45 ft1/ min/ft* for felted fabrics is allowed for filtering air from asbestos ore dryers. Each square yard of felted fabric must weigh at least 14 ounces and be at least one-sixteenth inch thick throughout. Synthetic fabrics must not contain fill yarn other than that which is spun. <b) If the use of fabric filters creates a fire or explosion hazard, the adminis trator may authorize the use of wet col lectors designed to operate with a unit contacting energy of at least 40 inches water gage pressure. (c) The administrator may authorize the use of filtering equipment other than that described in paragraphs (a) and (b) of this section if the owner or operator demonstrates to the satisfaction of the administrator that the filtering of par ticulate asbestos material is equivalent to that of the described equipment. (d) All air-cleaning equipment au thorized by this section must be properly installed, used, operated, and maintained. Bypass devices may be used only during upset or emergency conditions and then only for so long as it takes to shut down the operation generating the particulate asbestos material. 61.24 Hpporling. The owner or operator of any existing source to which this subpart is applicable shall, within 90 days after the effective date, provide the following information to the administrator: (a) A description of the emission con trol equipment used for each process: (b) If a fabric filter device is used to control emissions, the pressure drop across the fabric filter in inches water gage. (1) If the fabric filter device utilizes a woven fabric, the airflow permeability in ft'/min/ft-; and, if the fabric is syn thetic, indicate whether the fill yarn is spun or not spun. (2) If the fabric filter device utilizes a felted fabric, the density in oz/yd\ the minimum thickness In inches, and the airflow permeability m ftVmin/ft1. <c) Such information shall accompany the information required by 61.10. The appropriate form is contained in appen dix A to this part.
