Alabama Administrative Code › Title 335 - ALABAMA DEPARTMENT OF ENVIRONMENTAL MANAGEMENT › AIR DIVISION - AIR POLLUTION CONTROL PROGRAM › Chapter 335-3-4 - CONTROL OF PARTICULATE EMISSIONS › Section 335-3-4-.15 - Secondary Lead Smelters

Current through Register Vol. 42, No. 9, June 28, 2024
(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.
