Applicability and Compliance Dates
§
63.10880 Am I subject to this subpart?
(a) You are subject to this subpart if you own or operate an iron and steel foundry that is an area source of hazardous air pollutant (HAP) emissions.
(b) This subpart applies to each new or existing affected source. The affected source is each iron and steel foundry.
(1) An affected source is existing if you commenced construction or reconstruction of the affected source before September 17, 2007.
(2) An affected source is new if you commenced construction or reconstruction of the affected source on or after September 17, 2007. If an affected source is
not new pursuant to the preceding sentence, it is not new as a result of a change in its compliance obligations pursuant to §63.10881(d).
(c) On and after January 2, 2008, if your iron and steel foundry becomes a major source as defined in §
63.2, you must meet the requirements of 40 CFR part
63, subpart EEEEE.
(d) This subpart does not apply to research and development facilities, as defined in section 112(c)(7) of the Clean Air Act.
(e) You are exempt from the obligation to obtain a permit under 40 CFR part 70 or 40 CFR part 71, provided you are not otherwise required by law to obtain a
permit under 40 CFR 70.3(a) or 40 CFR 71.3(a). Notwithstanding the previous sentence, you must continue to comply with the provisions of this subpart.
(f) If you own or operate an existing affected source, you must determine the initial applicability of the requirements of this subpart to a small foundry or a large
foundry based on your facility's metal melt production for calendar year 2008. If the metal melt production for calendar year 2008 is 20,000 tons or less, your
area source is a small foundry. If your metal melt production for calendar year 2008 is greater than 20,000 tons, your area source is a large foundry. You must
submit a written notification to the Administrator that identifies your area source as a small foundry or a large foundry no later than January 2, 2009.
(g) If you own or operate a new affected source, you must determine the initial applicability of the requirements of this subpart to a small foundry or a large
foundry based on your facility's annual metal melting capacity at startup. If the annual metal melting capacity is 10,000 tons or less, your area source is a
small foundry. If the annual metal melting capacity is greater than 10,000 tons, your area source is a large foundry. You must submit a written notification to
the Administrator that identifies your area source as a small foundry or a large foundry no later than 120 days after startup.
§
63.10881 What are my compliance dates?

(2) If your facility is initially classified as a large foundry (or your small foundry subsequently becomes a large foundry), you must comply with the
requirements for a large foundry for at least 3 years before reclassifying your facility as a small foundry. After 3 years, you may reclassify your facility as a
small foundry provided your most recent annual metal melt capacity is 10,000 tons or less. If you reclassify your large foundry as a small foundry, you must
notify the Administrator within 30 days and comply with the requirements for a small foundry no later than the date your melting equipment was removed or
taken out of service, if applicable, or the date of issuance for your revised State or Federal operating permit.
Pollution Prevention Management Practices for New and Existing Affected Sources
§
63.10885 What are my management practices for metallic scrap and mercury
switches?
(a)
Metallic scrap management program.
For each segregated metallic scrap storage area, bin or pile, you must comply with the materials acquisition
requirements in paragraph (a)(1) or (2) of this section. You must keep a copy of the material specifications onsite and readily available to all personnel with
material acquisition duties, and provide a copy to each of your scrap providers. You may have certain scrap subject to paragraph (a)(1) of this section and
other scrap subject to paragraph (a)(2) of this section at your facility provided the metallic scrap remains segregated until charge make-up.
(1)
Restricted metallic scrap.
You must prepare and operate at all times according to written material specifications for the purchase and use of only metal
ingots, pig iron, slitter, or other materials that do not include post-consumer automotive body scrap, post-consumer engine blocks, post-consumer oil filters,
oily turnings, lead components, chlorinated plastics, or free liquids. For the purpose of this subpart, “free liquids” is def
ined as material that fails the paint filter
test by EPA Method 9095B, “Paint Filter Liquids Test” (revision 2), November 2004 (incorporated by reference—
see §
63.14). The requirements for no free
liquids do not apply if the owner or operator can demonstrate that the free liquid is water that resulted from scrap exposure to rain.
(2)
General iron and steel scrap.
You must prepare and operate at all times according to written material specifications for the purchase and use of only iron
and steel scrap that has been depleted (to the extent practicable) of organics and HAP metals in the charge materials used by the iron and steel foundry. The
materials specifications must include at minimum the information specified in paragraph (a)(2)(i) or (ii) of this section.
(i) Except as provided in paragraph (a)(2)(ii) of this section, specifications for metallic scrap materials charged to a scrap preheater or metal melting furnace to
be depleted (to the extent practicable) of the presence of used oil filters, chlorinated plastic parts, accessible lead- containing components (such as batteries
and wheel weights), and a program to ensure the scrap materials are drained of free liquids.
(ii) For scrap charged to a cupola metal melting furnace that is equipped with an afterburner, specifications for metallic scrap materials to be depleted (to the
extent practicable) of the presence of chlorinated plastics, accessible lead- containing components (such as batteries and wheel weights), and a program to
ensure the scrap materials are drained of free liquids.
(b)
Mercury requirements.
For scrap containing motor vehicle scrap, you must procure the scrap pursuant to one of the compliance options in paragraphs
(b)(1), (2), or (3) of this section for each scrap provider, contract, or shipment. For scrap that does not contain motor vehicle scrap, you must procure the scrap
pursuant to the requirements in paragraph (b)(4) of this section for each scrap provider, contract, or shipment. You may have one scrap provider, contract, or
shipment subject to one compliance provision and others subject to another compliance provision.
(1)
Site-specific plan for mercury switches.
You must comply with the requirements in paragraphs (b)(1)(i) through (v) of this section.
(i) You must include a requirement in your scrap specifications for removal of mercury switches from vehicle bodies used to make the scrap.
(ii) You must prepare and operate according to a plan demonstrating how your facility will implement the scrap specification in paragraph (b)(1)(i) of this
section for removal of mercury switches. You must submit the plan to the Administrator for approval. You must operate according to the plan as submitted
during the review and approval process, operate according to the approved plan at all times after approval, and address any deficiency identified by the
Administrator or delegated authority within 60 days following disapproval of a plan. You may request approval to revise the plan and may operate according to
the revised plan unless and until the revision is disapproved by the Administrator or delegated authority. The Administrator or delegated authority may change
the approval status of the plan upon 90-days written notice based upon the semiannual report or other information. The plan must include:
(A) A means of communicating to scrap purchasers and scrap providers the need to obtain or provide motor vehicle scrap from which mercury switches have
been removed and the need to ensure the proper management of the mercury switches removed from the scrap as required under the rules implementing
subtitle C of the Resource Conservation and Recovery Act (RCRA) (40 CFR parts 261 through 265 and 268). The plan must include documentation of
direction to appropriate staff to communicate to suppliers throughout the scrap supply chain the need to promote the removal of mercury switches from
end-of-life vehicles. Upon the request of the Administrator or delegated authority, you must provide examples of materials that are used for outreach to
suppliers, such as letters, contract language, policies for purchasing agents, and scrap inspection protocols;
(B) Provisions for obtaining assurance from scrap providers motor vehicle scrap provided to the facility meet the scrap specification;
(C) Provisions for periodic inspections or other means of corroboration to ensure that scrap providers and dismantlers are implementing appropriate steps to
minimize the presence of mercury switches in motor vehicle scrap and that the mercury switches removed are being properly managed, including the
minimum frequency such means of corroboration will be implemented; and
(D) Provisions for taking corrective actions (i.e., actions resulting in scrap providers removing a higher percentage of mercury switches or other
mercury-containing components) if needed, based on the results of procedures implemented in paragraph (b)(1)(ii)(C) of this section).
(iii) You must require each motor vehicle scrap provider to provide an estimate of the number of mercury switches removed from motor vehicle scrap sent to
the facility during the previous year and the basis for the estimate. The Administrator may request documentation or additional information at any time.
(iv) You must establish a goal for each scrap supplier to remove at least 80 percent of the mercury switches. Although a site-specific plan approved under
paragraph (b)(1) of this section may require only the removal of convenience light switch mechanisms, the Administrator will credit all documented and
verifiable mercury-containing components removed from motor vehicle scrap (such as sensors in anti-locking brake systems, security systems, active ride
control, and other applications) when evaluating progress towards the 80 percent goal.
(v) For each scrap provider, you must submit semiannual progress reports to the Administrator that provide the number of mercury switches removed or the
weight of mercury recovered from the switches, the estimated number of vehicles processed, an estimate of the percent of mercury switches removed, and
certification that the removed mercury switches were recycled at RCRA-permitted facilities or otherwise properly managed pursuant to RCRA subtitle C
regulations referenced in paragraph (b)(1)(ii)(A) of this section. This information can be submitted in aggregate form and does not have to be submitted for
each shipment. The Administrator may change the approval status of a site-specific plan following 90-days notice based on the progress reports or other
information.
(2)
Option for approved mercury programs.
You must certify in your notification of compliance status that you participate in and purchase motor vehicle scrap
only from scrap providers who participate in a program for removal of mercury switches that has been approved by the Administrator based on the criteria in
paragraphs (b)(2)(i) through (iii) of this section. If you purchase motor vehicle scrap from a broker, you must certify that all scrap received from that broker was
obtained from other scrap providers who participate in a program for the removal of mercury switches that has been approved by the Administrator based on
the criteria in paragraphs (b)(2)(i) through (iii) of this section. The National Mercury Switch Recovery Program and the State of Maine Mercury Switch
Removal Program are EPA-approved programs under paragraph (b)(2) of this section unless and until the Administrator disapproves the program (in part or
in whole) under paragraph (b)(2)(iii) of this section.
(i) The program includes outreach that informs the dismantlers of the need for removal of mercury switches and provides training and guidance for removing
mercury switches;
(ii) The program has a goal to remove at least 80 percent of mercury switches from motor vehicle scrap the scrap provider processes. Although a program
approved under paragraph (b)(2) of this section may require only the removal of convenience light switch mechanisms, the Administrator will credit all
documented and verifiable mercury-containing components removed from motor vehicle scrap (such as sensors in anti- locking brake systems, security
systems, active ride control, and other applications) when evaluating progress towards the 80 percent goal; and
(iii) The program sponsor agrees to submit progress reports to the Administrator no less frequently than once every year that provide the number of mercury
switches removed or the weight of mercury recovered from the switches, the estimated number of vehicles processed, an estimate of the percent of mercury
switches recovered, and certification that the recovered mercury switches were recycled at facilities with permits as required under the rules implementing
subtitle C of RCRA (40 CFR parts 261 through 265 and 268). The progress reports must be based on a database that includes data for each program
participant; however, data may be aggregated at the State level for progress reports that will be publicly available. The Administrator may change the
approval status of a program or portion of a program (e.g., at the State level) following 90-days notice based on the progress reports or on other information.
(iv) You must develop and maintain onsite a plan demonstrating the manner through which your facility is participating in the EPA-approved program.
(A) The plan must include facility-specific implementation elements, corporate-wide policies, and/or efforts coordinated by a trade association as appropriate
for each facility.
(B) You must provide in the plan documentation of direction to appropriate staff to communicate to suppliers throughout the scrap supply chain the need to
promote the removal or mercury switches from end-of-life vehicles. Upon the request of the Administrator or delegated authority, you must provide examples
of materials that are used for outreach to suppliers, such as letters, contract language, policies for purchasing agents, and scrap inspection protocols.
(C) You must conduct periodic inspections or other means of corroboration to ensure that scrap providers are aware of the need for and are implementing
appropriate steps to minimize the presence of mercury in scrap from end-of-life vehicles.
(3)
Option for specialty metal scrap.
You must certify in your notification of compliance status and maintain records of documentation that the only materials
from motor vehicles in the scrap are materials recovered for their specialty alloy (including, but not limited to, chromium, nickel, molybdenum, or other alloys)
content (such as certain exhaust systems) and, based on the nature of the scrap and purchase specifications, that the type of scrap is not reasonably
expected to contain mercury switches.
(4)
Scrap that does not contain motor vehicle scrap.
For scrap not subject to the requirements in paragraphs (b)(1) through (3) of this section, you must certify
in your notification of compliance status and maintain records of documentation that this scrap does not contain motor vehicle scrap.
§
63.10886 What are my management practices for binder formulations?

pounds of PM or total metal HAP per ton of metal melted from the group of all metal melting furnaces at your foundry. You must calculate and record the
weighted average pounds per ton emissions rate for the group of all metal melting furnaces at the foundry determined from the performance test procedures
in §
63.10898(d) and (e).
§
63.10898 What are my performance test requirements?
(a) You must conduct a performance test to demonstrate initial compliance with the applicable emissions limits for each metal melting furnace or group of all
metal melting furnaces that is subject to an emissions limit in §
63.10895(c) and for each building or structure housing foundry operations that is subject to the
opacity limit for fugitive emissions in §
63.10895(e). You must conduct the test within 180 days of your compliance date and report the results in your
notification of compliance status.
(1) If you own or operate an existing iron and steel foundry, you may choose to submit the results of a prior performance test for PM or total metal HAP that
demonstrates compliance with the applicable emissions limit for a metal melting furnace or group of all metal melting furnaces provided the test was
conducted within the last 5 years using the methods and procedures specified in this subpart and either no process changes have been made since the test,
or you can demonstrate that the results of the performance test, with or without adjustments, reliably demonstrate compliance with the applicable emissions
limit despite such process changes.
(2) If you own or operate an existing iron and steel foundry and you choose to submit the results of a prior performance test according to paragraph (a)(1) of
this section, you must submit a written notification to the Administrator of your intent to use the previous test data no later than 60 days after your compliance
date. The notification must contain a full copy of the performance test and contain information to demonstrate, if applicable, that either no process changes
have been made since the test, or that the results of the performance test, with or without adjustments, reliably demonstrate compliance despite such process
changes.
(3) If you have an electric induction furnace equipped with an emissions control device at an existing foundry, you may use the test results from another
electric induction furnace to demonstrate compliance with the applicable PM or total metal HAP emissions limit in §
63.10895(c) provided the furnaces are
similar with respect to the type of emission control device that is used, the composition of the scrap charged, furnace size, and furnace melting temperature.
(4) If you have an uncontrolled electric induction furnace at an existing foundry, you may use the test results from another electric induction furnace to
demonstrate compliance with the applicable PM or total metal HAP emissions limit in §
63.10895(c) provided the test results are prior to any control device and
the electric induction furnaces are similar with respect to the composition of the scrap charged, furnace size, and furnace melting temperature.
(5) For electric induction furnaces that do not have emission capture systems, you may install a temporary enclosure for the purpose of representative
sampling of emissions. A permanent enclosure and capture system is not required for the purpose of the performance test.
(b) You must conduct subsequent performance tests to demonstrate compliance with all applicable PM or total metal HAP emissions limits in §
63.10895(c) for
a metal melting furnace or group of all metal melting furnaces no less frequently than every 5 years and each time you elect to change an operating limit or
make a process change likely to increase HAP emissions.
(c) You must conduct each performance test according to the requirements in §
63.7(e)(1), Table 1 to this subpart, and paragraphs (d) through (g) of this
section.
(d) To determine compliance with the applicable PM or total metal HAP emissions limit in §
63.10895(c) for a metal melting furnace in a lb/ton of metal charged
format, compute the process-weighted mass emissions (E
p
) for each test run using Equation 1 of this section:

Where:

E
p
= Process- weighted mass emissions rate of PM or total metal HAP, pounds of PM or total
metal HAP per ton (lb/ton) of metal charged;
C = Concentration of PM or total metal HAP measured during performance test run, grains per
dry standard cubic foot (gr/dscf);
Q = Volumetric flow rate of exhaust gas, dry standard cubic feet per hour (dscf/hr);
T = Total time during a test run that a sample is withdrawn from the stack during melt
production cycle, hr;
P = Total amount of metal charged during the test run, tons; and
K = Conversion factor, 7,000 grains per pound.
(e) To determine compliance with the applicable emissions limit in §
63.10895(c) for a group of all metal melting furnaces using emissions averaging,
(1) Determine and record the monthly average charge rate for each metal melting furnace at your iron and steel foundry for the previous calendar month; and
(2) Compute the mass-weighted PM or total metal HAP using Equation 2 of this section.

Where:

E
C
= The mass-weighted PM or total metal HAP emissions for the group of all metal melting
furnaces at the foundry, pounds of PM or total metal HAP per ton of metal charged;
E
pi
= Process-weighted mass emissions of PM or total metal HAP for individual emission unit i
as determined from the performance test and calculated using Equation 1 of this section,
pounds of PM or total metal HAP per ton of metal charged;
T
ti
= Total tons of metal charged for individual emission unit i for the calendar month prior to the
performance test, tons; and
n = The total number of metal melting furnaces at the iron and steel foundry.
(3) For an uncontrolled electric induction furnace that is not equipped with a capture system and has not been previously tested for PM or total metal HAP,
you may assume an emissions factor of 2 pounds per ton of PM or 0.13 pounds of total metal HAP per ton of metal melted in Equation 2 of this section instead
of a measured test value. If the uncontrolled electric induction furnace is equipped with a capture system, you must use a measured test value.
(f) To determine compliance with the applicable PM or total metal HAP emissions limit for a metal melting furnace in §
63.10895(c) when emissions from one
or more regulated furnaces are combined with other non-regulated emissions sources, you may demonstrate compliance using the procedures in paragraphs
(f)(1) through (3) of this section.
(1) Determine the PM or total metal HAP process-weighted mass emissions for each of the regulated streams prior to the combination with other exhaust
streams or control device.
(2) Measure the flow rate and PM or total metal HAP concentration of the combined exhaust stream both before and after the control device and calculate the
mass removal efficiency of the control device using Equation 3 of this section.

Where:

E
i
= Mass emissions rate of PM or total metal HAP at the control device inlet, lb/hr;
E
o
= Mass emissions rate of PM or total metal HAP at the control device outlet, lb/hr.
(3) Meet the applicable emissions limit based on the calculated PM or total metal HAP process-weighted mass emissions for the regulated emissions source
using Equation 4 of this section:
