Current through Register Vol. 49, No. 6, March 15, 2024
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 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.
1. Doe Run Resource Recycling Division in
Boss, Missouri, shall limit main stack lead emissions into the atmosphere to
0.000087 grains of lead per dry standard cubic foot of air. This installation
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 twenty-four (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 x 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. Copies can be obtained from the U.S. Publishing
Office Bookstore, 710 N. Capitol Street N W, Washington, DC 20401. This rule
does not incorporate any subsequent amendments or additions.
