Current through Register Vol. 43, No. 1, October 31, 2024
Section 335-3-4-.15 - Secondary Lead Smelters(1) All blast (cupola) or reverberatory furnaces at a secondary lead smelter must be equipped with a capture system for fugitive emissions from the tapping and charging operations with the exception of a reverberatory furnace lead tap. Such capture systems, including hoods, ducts, and fans, shall be designed, operated and maintained to achieve maximum reasonable capture and shall be vented to a control device with at least 99.5 percent collection efficiency.(2) All alloying kettles or pots at a secondary lead smelter must be equipped with a vented cover that will be in place at all times the kettle contains molten lead except when access is necessary for casting or refining operations. The capture system, including covers, ducts, and fans, shall be designed, operated and maintained to achieve maximum reasonable capture and shall be vented to a control system with at least 90 percent collection efficiency.(3) No owner or operator of a secondary lead smelter shall discharge or cause the discharge into the atmosphere from a blast (cupola) or reverberatory furnace primary exhaust stack any gases which contain particulate matter in excess of 50.0 mg/dscm (0.022 gr/dscf).(4) Owners and operators of a secondary lead plant shall minimize fugitive dust at the plant by good housekeeping practices that will include: frequent sweeping of the plant and grounds; shielding the handling of flue dust from the wind; and enclosing, sheltering or otherwise treating all flue dust storage piles to prevent wind erosion.(5)Compliance. Affected facilities shall be in compliance with the provisions of paragraphs (1) through (4) of this Rule at the earliest possible date, but no later than October 31, 1982.(6) This paragraph applies to existing secondary lead smelters located in Pike County. (a) Visible emissions escaping the capture system for the charging door shall not exceed 10% opacity when charging the blast furnace as determined by 40 CFR 60, Appendix A, Method 9 excluding Section 2.5. Visible emissions escaping the capture system for the closed charging door on the blast furnace shall not exceed 5% opacity during furnace operation as determined by 40 CFR 60, Appendix A, Method 9 excluding Section 2.5.(b) Visible emissions escaping the capture system for the slag tap and lead tap on blast furnaces shall not exceed 1% opacity as determined by 40 CFR 60, Appendix A, Method 9.(c) All lead bearing material (excluding the material from the battery breaking operation, material stored in closed containers, and other material which has been excluded in writing, by the Director) will be unloaded and stored in enclosed buildings. These buildings shall have no openings directly to the atmosphere except doors which may be opened only during egress or ingress or while material is being added or removed from the buildings. The buildings will be constructed such that stored material is transported to the smelter building without leaving an enclosed area.(d) All paved areas external to buildings on which raw materials are handled will be clearly marked and kept wet by watering devices so that no visible emissions are observed emanating from the paved areas. All vehicles leaving the areas so designated by this Rule shall have their wheels and undercarriages washed immediately prior to leaving the area. Records must be kept of all vehicles leaving the area. Said records shall be maintained for a minimum of two years following date of recorded information.(e) Paved areas not designated as necessitating wetting by subparagraph (d) of this paragraph above shall be vacuum swept twice daily except under specific conditions as approved by the Director. Records must be kept documenting when sweeping is done and any reason for not sweeping (such as equipment breakdown, inclement weather conditions). Said records shall be maintained for a minimum of two years following date of recorded information.(f) Unpaved areas will be planted with grass or other ground cover or treated with lignosulfonate or equivalent surfactant on a schedule approved in writing by the Director. An evergreen vegetation boundary approved by the Director shall be planted and maintained on the northwest and north side of the plant.(g)Compliance. 1. Except as provided under subparagraph (g)2. of this paragraph, affected facilities shall be in compliance with this paragraph within twelve (12) months of adoption.2. Nothing in this Rule shall prevent the owner or operator of an affected facility from submitting to the Director a proposed alternative compliance schedule provided: (i) the proposed alternative schedule is submitted within two (2) months of adoption; and(ii) the proposed alternative schedule contains increments of progress; and(iii) sufficient documentation and certification from appropriate suppliers, contractors, manufacturers, or fabricators are submitted by the owner or operator of the affected source to justify the dates proposed for the increments of progress; and(iv) all alternative compliance schedules proposed or promulgated under this Rule shall provide for compliance of the source with this Rule as expeditiously as practicable, but no later than December 31, 1987.
