M. O. VARNER M1IU4V AMERICAN SMELTING AND REFINING COMPANY DEPARTMENT OF ENVIRONMENTAL SCIENCES 3422 SOUTH - 700 WOT, SALT LAKE CITY, UTAH Will October 31, 1974 Mr. M. 0. Varner Building Proposed Amendments to National Emission Standards for Asbestos I have attached copies of the October 25, 1974, Federal Register which contains proposed amendments for hazardous air pollutants, ~ ' including asbestos. The proposed amendments appear to have an impact on ASARCO operations. 1: There are a number of requirements that apply to the demolition or renovation of a tank, furnace, or structural member that is insulated or fire-proofed with "friable* asbestos material. The proposed requirements are: a: Written notice of intention to demolish or renovate. b: Control procedures to prevent emissions of particulate asbes tos material to outside air. c: A prohibition on visible emissions. d: Proper waste disposal of the asbestos-containing materials. 2: A ban on molded insulating and wet-applied insulating materials (which are "friable*after drying) containing commercial asbestos. The insulating cement or "lagging" used at the various smelters would appear to fall within this category. 3: A requirement of no visible emissions to the outside air from the collection, processing, packaging, transporting, or deposition of asbestos-containing waste which is generated by asbestos fabri cating sources. This requirement may affect the proposed (or installed) local ventilation systems at various carpentry shops, such as Tacoma, Corpus Christ!, and Globe, where transits and other asbestos-containing materials are used. * "4 ASARCO ELP 0000709 . 2 4: A number of requirements for waste disposal sites where asbestoscontaining waste has been deposited, including warning signs, fencing, use of dust suppression agents, a cover of compacted material. These requirements have an obvious application to the open dump at the CAPCO Van Buren property. Comments on these proposed amendments should be submitted to the EPA no later than December S, 1974.

In accordance with ASSSSTOS Manufacturing, It is the Administra tor's judgment that the manufacture at shotgun shells and the manufacture of asphalt concrete are major sources of as bestos which should be added to the Uat' of nine manufacturing operations cov ered by the promulgated asbestos stand ard. The asbestos emissions from the two additional manufacturing operations will be limited to the some extent as those of the other nino manufacturing opera tions: Visible emissions to the outside air are prohibited, but an option of using specified air-cleaning methods Is pro vided. free products arc now available for the complcto range of temperature require ments.
