326 IAC 20-13.1-8 Fugitive dust source requirements

Sec. 8. (a) The owner or operator of a secondary lead smelter shall prepare and at all times operate in accordance with a standard operating procedures manual that describes in detail the measures that will be put in place and implemented to control the fugitive dust emissions from the following: (1) Plant roadways. (2) Plant buildings. (3) Accidental releases. (4) Battery storage areas. (5) Equipment maintenance activities. (6) Material storage areas. (7) Material handling areas. (b) The owner or operator of a secondary lead smelter shall submit the standard operating procedures manual to the department for review and approval in accordance with section 13(b) of this rule and at any time changes are made. (c) The controls specified in the standard operating procedures manual must, at a minimum, include the following requirements: (1) Where a cleaning practice is specified, the owner or operator of a secondary lead smelter shall clean by wet wash or a vacuum equipped with a filter rated by the manufacturer to achieve ninety-nine and ninety-seven hundredths percent (99.97%) capture efficiency for three-tenths (0.3) micron particles in a manner that does not generate fugitive lead dust. (2) The owner or operator of a secondary lead smelter shall pave all areas subject to vehicle traffic and shall clean the pavement twice per day, except on days when natural precipitation makes cleaning unnecessary or when sand or a similar material has been spread on plant roadways to provide traction on ice or snow. Limited access and limited use roadways such as unpaved roads to remote locations on the property may be exempt from this requirement if they are used no more than one (1) round trip per day. (3) The owner or operator of a secondary lead smelter shall initiate cleaning of all affected areas within one (1) hour after detection of any accidental release of lead dust that exceeds ten (10) pounds in accordance with the reportable quantity requirements for lead at 40 CFR 302.4*. (4) The owner or operator of a secondary lead smelter shall inspect any batteries that are not stored in a total enclosure once each week and move any broken batteries to an enclosure within seventy-two (72) hours of identification. The owner or operator of a secondary lead smelter shall clean residue from broken batteries within seventy-two (72) hours of identification. (5) The owner or operator of a secondary lead smelter shall wash each vehicle at each exit of the material storage and handling areas. The vehicle wash shall include washing of tires, undercarriage, and exterior surface of the vehicle followed by vehicle inspection. (6) The owner or operator of a secondary lead smelter shall perform all maintenance activities that could generate lead dust in a manner that minimizes emissions of fugitive dust. This shall include one (1) or more of the following: (A) Performing maintenance inside a total enclosure maintained at negative pressure. (B) Performing maintenance inside a temporary enclosure and use of a vacuum system either equipped with a filter rated by the manufacturer to achieve a capture efficiency of ninety-nine and ninety-seven hundredths percent (99.97%) for three-tenths (0.3) micron particles or routed to an existing control device permitted for this activity. (C) Performing maintenance inside a partial enclosure and use of wet suppression sufficient to prevent dust formation. (D) Decontamination of equipment prior to removal from an enclosure. (E) Immediate repair of ductwork or structure leaks without an enclosure if the time to construct a temporary enclosure would exceed the time to make a temporary or permanent repair, or if construction of an enclosure would cause a higher level of emissions than if an enclosure were not constructed. (F) Activities required for inspection of fabric filters and maintenance of filters that are in need of removal and replacement are not required to be conducted inside of total enclosures. Used fabric filters shall be placed in sealed plastic bags or containers prior to removal from a baghouse. (7) The owner or operator of a secondary lead smelter shall collect and transport all lead-bearing dust within closed conveyor systems or in sealed, leak-proof containers unless the collection and transport activities are contained within a total enclosure. All other lead-bearing material must be contained and covered for transport outside of a total enclosure in a manner that prevents spillage or dust formation. Intact batteries and lead ingot product are exempt from the requirement to be covered for transport. (d) The standard operating procedures manual must specify that records be maintained of all pavement cleaning, vehicle washing, and battery storage inspection activities performed to control fugitive dust emissions. (e) The owner or operator of a secondary lead smelter shall pave all grounds or plant ground cover sufficient to prevent wind-blown dust. The owner or operator of a secondary lead smelter may use dust suppressants on unpaved areas that will not support a ground cover, such as roadway shoulders, steep slopes, and limited access and limited use roadways. (f) As provided in the July 1, 2012, edition of 40 CFR 63.6(g)*, as an alternative to the requirements specified in this section, the owner or operator of a secondary lead smelter can demonstrate to the department that an alternative measure is equivalent or more protective of the environment than a practice described in this section. *These documents are incorporated by reference.
