Restriction of Emissions of Lead From Specific Lead Smelter-Refinery Installations

PURPOSE: This rule establishes maximum allowable rates of emissions of lead from stacks in specific lead-smelter installations, except where New Source Performance Standards apply (as provided in 10 CSR 10-6.070). It also provides for the operation and maintenance of equipment and procedures specific to controlling lead emissions to the ambient air, both from stacks and from the fugitive emissions that escape stack collection systems at these installations. (1) Applicability. (A) This rule applies to existing installations in Missouri engaged in specific smelting and refining for the production of lead. (B) Operation and Maintenance of Lead Emissions Control Equipment and Procedures. The owner or operator of any specific lead smelter shall operate and maintain all lead emissions control equipment and perform all procedures as required by this rule. (2) Definitions. Definitions of certain terms specified in this rule, other than those specified in this rule section, may be found in 10 CSR 10-6.020. (3) General Provisions. (A) Operational Malfunction. 1. The owner or operator shall maintain a file which identifies the date and time of any significant malfunction of plant process operations or of emission control equipment which results in increased lead emissions. The file also shall contain a description of any corrective action taken, including TABLE 3.

RESOURCES the date and time. 10 CSR 10-6.050 Start-Up, Shutdown, and Malfunction Conditions shall apply. 2. All of these files relating to operational malfunction shall be retained for a minimum of two (2) years and, upon request, shall be made available to the director. (B) Provisions Pertaining to Limitations of Lead Emissions from Specific Installations. Doe Run Resource Recycling Division in Boss, Missouri, shall limit total lead production to one hundred seventy-five thousand (175,000) tons per year. (C) Provisions Pertaining to Limitations of Lead Emissions From Other Than Stacks at All Installations. 1. The owner or operator shall control fugitive emissions of lead from all process and area sources at an installation by measures described in a work practice manual identified in paragraph (3)(C)2. of this rule. It is a violation of this rule to fail to adhere to the requirements of these work practices. 2. Work practice manual. A. The owner or operator shall prepare, submit for approval, and then implement a process and area-specific work practice manual that will apply to locations of fugitive lead emissions at the installation. B. The manual shall be the method of determining compliance with the provisions of this section. Failure to adhere to the work practices in the manual is a violation of this rule. C. Any change to the manual proposed by the owner or operator following the initial approval shall be requested in writing to the director. Any proposed change shall demonstrate that the change in the work practice will not lessen the effectiveness of the fugitive emission reductions for the work practice involved. Written approval by the director is required before any change becomes effective in the manual. D. If the director determines a change in the work practice manual is necessary, the director will notify the owner or operator of that installation. The owner or operator shall revise the manual to reflect these changes and submit the revised manual within thirty (30) days of receipt of notification. These changes shall become effective following written approval of the revised manual by the director. (4) Reporting and Record Keeping. (A) The operator shall keep records and files generated by the work practice manual’s implementation. (B) The work practice manual shall contain the requirement that records of inspections made by the operator of fugitive emissions control equipment such as hoods, air ducts, and exhaust fans be maintained by the operator. (C) The Doe Run Resource Recycling Division, Boss, Missouri, operator shall keep records that demonstrate compliance with the emissions limitations described in subsection (3)(B) using the sampling methods described in subsection (5)(E) of this rule. These records shall be maintained on-site in accordance with record keeping and reporting requirements in subsection (5)(E) of this rule. (D) Records shall be kept for a minimum of two (2) years at the installation and shall be made available upon request of the director for purposes of determining compliance. (5) Test Methods. (A) The method of determining the concentration of visible emissions from stack sources shall be Method 9—Visual Determination of the Opacity of Emissions from Stationary Sources or Method 22—Visual Determination of Fugitive Emissions from Material Sources and Smoke Emissions from Flares as specified in 10 CSR 10-6.030(22). (B) The method of measuring lead in stack gases shall be Method 12—Determination of Inorganic Lead Emissions from Stationary Sources as specified in 10 CSR 10-6.030(22). (C) The method of quantifying the determination of compliance with the emission limitations from stacks in this rule shall be as follows: 1. Three (3) stack samplings shall be planned to be conducted for any one (1) stack within a twenty-four (24)- hour period in accordance with subsection (5)(B) of this rule. If this cannot be done due to weather, operating, or other preventative conditions that develop during the twentyfour (24)-hour period, then the remaining samplings may be conducted in a reasonable time determined by the director following the twenty-four (24)-hour period; 2. Each stack sample shall have a sampling time of at least one (1) hour; 3. The process(es) producing the emissions to that stack being tested shall be operating at a minimum of ninety percent (90%) of capacity of the process(es) for the full duration of the samplings; and 4. The emission rate to be used for compliance determination shall be quantified by using the following formula: Ec = T avg lbs per hour × 24 hours = lbs per 24 hours Where: Ec = 24-hour emission rate extrapolated from stack sampling results used for compliance determination; and T avg = Summation of hourly emission rates of three (3) stack sampling results, divided by three (3) for the average hourly rate. (D) The method of measuring lead in the ambient atmosphere shall be the reference method as specified in 10 CSR 10-6.040(4) (G). (E) The methods for demonstrating compliance at the Doe Run Resource Recycling Division in Boss, Missouri, shall be those specified in 40 CFR 63, subpart X. 40 CFR 63, Subpart X promulgated as of July 1, 2018 is hereby incorporated by reference in this rule, as published by the Office of the Federal Register.
