OAR 340-248-0210: Emission Standards and Procedural Requirements: Asbestos Requirements for Mills, Roadways and Parking lots, and Manufacturing Operations

(1) Emission standard for asbestos mills. No person may cause or allow to be discharged into the atmosphere visible emissions, including fugitive emissions, from any asbestos milling operation except as provided under OAR 340-248-0275(2) Air Cleaning. For purposes of this rule, the presence of uncombined water in the emission plume is not a violation of the visible emission requirement. Outside storage of asbestos materials is not part of an asbestos mill operation. The owner or operator of an asbestos mill must meet the following requirements: (a) Monitor each potential source of asbestos emissions from a part of the mill 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 operations. The monitoring must be by visual observation of at least 15 seconds duration per source of emissions. (b) Inspect each air cleaning device at least once each week for proper operation and for changes that signal the potential for malfunction 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, submit to DEQ, revise as necessary, and implement a written maintenance plan to include, at a minimum, a maintenance schedule and recordkeeping plan. (c) Maintain records of the results of visible emissions monitoring and air cleaning device inspections using a format approved by DEQ and including the following information: (A) Date and time of each inspection; (B) Presence or absence of visible emissions; (C) Condition of fabric filters, including presence of tears, holes, and abrasions; (D) Presence of dust deposits on clean side of fabric filters; (E) Brief description of corrective actions taken, including date and time; and (F) Daily hours of operation for each air cleaning device. (d) Furnish upon request, and make available at the affected facility during normal business hours for inspection by DEQ, all records this section requires. (e) Retain a copy of all monitoring and inspection records for at least two years. (f) Submit a copy of visible emission monitoring records to DEQ quarterly. The quarterly reports must be postmarked by the 30th day following the end of the calendar quarter. (g) Asbestos-containing waste material produced by an asbestos milling operation must be disposed of according to OAR 340-248-0280. (2) Roadways and Parking Lots. No person may construct or maintain, or allow to be constructed or maintained a roadway with asbestos tailings or asbestos-containing waste material on that roadway, unless (for asbestos tailings): (a) It is a temporary roadway on an area of asbestos ore deposits (asbestos mine); (b) It is a temporary roadway at an active asbestos mill site and is encapsulated with a resinous or bituminous binder. The encapsulated road surface must be maintained at least once per calendar year or within 12 months of road construction to prevent dust emissions; or (c) It is encapsulated in asphalt concrete meeting the specifications contained in Section 401 of Standard Specifications for Construction of Roads and Bridges on Federal Highway Projects, FP-85, 1985 , or their equivalent. (3) Manufacturing. No person may cause or allow to be discharged into the atmosphere visible emissions, except as provided in OAR 340-248-0275(2), from a building or structure in which manufacturing operations utilizing commercial asbestos are conducted, or directly from such manufacturing operations if they are conducted outside buildings or structures, or from other fugitive emissions. All asbestos-containing waste material a manufacturing operation produces must be disposed of according to OAR 340-248-0280. Visible emissions from boilers or other points not producing emissions directly from the manufacturing operation and having no possible asbestos material in the exhaust gases are not a violation of this rule. The presence of uncombined water in the exhaust plume is not a violation of the visible emission requirements: (a) Applicability. Manufacturing operations subject to this rule are as follows: (A) Manufacturing cloth, cord, wicks, tubing, tape, twine, rope, thread, yarn, roving, lap, or other textile materials; (B) Manufacturing cement products; (C) Manufacturing fire proofing and insulating materials; (D) Manufacturing friction products; (E) Manufacturing paper, millboard, and felt; (F) Manufacturing floor tile; (G) Manufacturing paints, coatings, caulks, adhesives, or sealants; (H) Manufacturing plastics and rubber materials; (I) Manufacturing chlorine, using asbestos diaphragm technology; (J) Manufacturing shotgun shell wads; (K) Manufacturing asphalt concrete; and (L) Other manufacturing operation that results or may result in the release of asbestos material to the ambient air. (b) The owner or operator of the manufacturing operation must monitor each potential source of asbestos emissions from a part of the manufacturing facility, including air cleaning devices, process equipment, and buildings housing material processing and handling equipment. Monitoring must be done at least once each day during daylight hours for visible emissions to the outside air during periods of operation and be by visual observation of at least 15 seconds duration per source of emissions. (c) The owner or operator of the manufacturing operation must 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, submit to DEQ, revise as necessary, and implement a written maintenance plan to include, at a minimum, a maintenance schedule and recordkeeping plan. (d) The owner or operator of a manufacturing operation must maintain records of the results of visible emission monitoring and air cleaning device inspections using a format DEQ approves and including the following information: (A) Date and time of each inspection; (B) Presence or absence of visible emissions; (C) Condition of fabric filters, including presence of tears, holes and abrasions; (D) Presence of dust deposits on clean side of fabric filters; (E) Brief description of corrective actions taken, including date and time; and (F) Daily hours of operation for each air cleaning device. (e) The owner or operator of a manufacturing operation must furnish upon request, and make available at the affected facility during normal business hours for inspection by DEQ, all records this section requires. (f) The owner or operator of a manufacturing operation must retain a copy of all monitoring and inspection records for at least two years. (g) The owner or operator of a manufacturing operation must submit quarterly a copy of the visible emission monitoring records to DEQ if visible emissions occurred during the report period. Quarterly reports must be postmarked by the 30th day following the end of the calendar quarter. (h) Asbestos-containing waste material produced by any asbestos manufacturing operation must be disposed of according to OAR 340-248-0280.
