Pollution Prevention Management Practices

Sec.  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 vendors. 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 defined as material that fails the paint filter
test by EPA Method 9095B, ``Paint Filter Liquids Test'' (Revision 2,
November 2004), as published in EPA Publication SW-846 ``Test Methods
for Evaluating Solid Waste, Physical/Chemical Methods'' (incorporated
by reference--see Sec.  63.14). The requirements of this paragraph
(a)(1) do not apply to the routine recycling of baghouse bags or other
internal process or maintenance materials in the furnace.
    (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) For scrap charged to a scrap preheater or metal melting furnace
that is not equipped with an afterburner, metallic scrap materials must
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 free liquids.
    (ii) For scrap charged to a cupola metal melting furnace that is
equipped with an afterburner, metallic scrap materials must be depleted
(to the extent practicable) of the presence of chlorinated plastics,
accessible lead-containing components (such as batteries and wheel
weights), and free liquids.
    (b) Mercury requirements. For each scrap provider, contract, or
shipment, you must procure all motor vehicle scrap pursuant to one of
the alternatives in paragraphs (b)(1), (2), or (3) of this section. You
may have one scrap provider, contract, or shipment subject to one
alternative and others subject to another alternative.
    (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. The Administrator
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
disposal of the mercury switches removed as required by the Resource
Conservation and Recovery Act (RCRA);
    (B) Provisions for obtaining assurance from scrap providers that
motor vehicle scrap provided to the facility meets the scrap
specification;
    (C) Provisions for periodic inspection, site visits, 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 they are properly disposing of
the mercury switches removed, including the minimum frequency such
means of corroboration will be implemented; and
    (D) Provisions for taking corrective actions 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 the removal of 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) 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 number of
vehicles processed, an estimate of the percent of mercury switches
recovered, and certification that the recovered mercury switches were
recycled at RCRA-permitted facilities. 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) Alternative 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.
    (i) There is an outreach program 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 for the removal of at least 80 percent
of mercury switches. 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 number of vehicles
processed, an estimate of the percent of mercury switches recovered,
and certification that the recovered mercury switches were recycled at
RCRA-permitted facilities. The Administrator may change the approval
status of a program following 90-days notice based on the progress
report or other information.
    (3) Alternative for specialty metal scrap. You must certify in your
notification of compliance status 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.

Sec.  63.10886  What are my management practices for binder
formulations?

    For each furfuryl alcohol warm box mold or core making line at a
new or existing iron and steel foundry, you must use a binder chemical
formulation that does not use methanol as a specific ingredient of the
catalyst formulation. This requirement does not apply to the resin

paragraph (d)(3) of this section.
    (3) In the event that a bag leak detection system alarm is
triggered, you must initiate corrective action to determine the cause
of the alarm within 1 hour of the alarm, initiate corrective action to
correct the cause of the problem within 24 hours of the alarm, and
complete corrective action as soon as practicable, but no later than 10
calendar days from the date of the alarm. You must record the date and
time of each valid alarm, the time you initiated corrective action, the
correction action taken, and the date on which corrective action was
completed. Corrective actions may include, but are not limited to:
    (i) Inspecting the bag house for air leaks, torn or broken bags or
filter media, or any other condition that may cause an increase in
emissions.
    (ii) Sealing off defective bags or filter media.

limitation (including operating limit), you must restore operation of
the emissions source (including the control device and associated
capture system) to its normal or usual manner or operation as
expeditiously as practicable in accordance with good air pollution
control practices for minimizing emissions. The response shall include
minimizing the period of any startup, shutdown or malfunction and
taking any necessary corrective actions to restore normal operation and
prevent the likely recurrence of the exceedance. You must record the
date and time correction action was initiated, the correction action
taken, and the date corrective action was completed.
    (h) If you choose to comply with an emissions limit in Sec.
63.10895(b) using emissions averaging, you must calculate and record
for each calendar month the 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 Sec.
63.10898(d) and (e).
    (i) Except for, as applicable, monitoring malfunctions, associated
repairs, and required quality assurance or control activities
(including, as applicable, calibration checks and required zero and
span adjustments), you must conduct all continuous monitoring (or must
collect data at all required intervals) at all times that the emissions
source is operating. Data recorded during monitoring malfunctions,
associated repairs, and required quality assurance or quality control
activities shall not be used for the purposes of this subpart,
including data averages and calculations, or fulfilling a minimum data
availability requirement, if applicable. You must use all the data
collected during all other periods in assessing the operation of the
control device and associated control system. A monitoring malfunction
is any sudden, infrequent, and not reasonably preventable failure of
the monitoring to provide valid data. Monitoring failures that are
caused in part by poor maintenance or careless operation are not

Sec.  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 Sec.  63.10895(b) and for each building or structure
housing foundry operations that is subject to the opacity limit for
fugitive emissions in Sec.  63.10895(d). 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 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.
    (b) You must conduct subsequent performance tests to demonstrate
compliance with the applicable emissions limit Sec.  63.10895(b) 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 Sec.  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 Sec.  63.10895(b) for a metal melting furnace in
a lb/ton of metal charged format, compute the process-weighted mass
emissions (Ep) for each test run using Equation 1 of this
section:

Where:

Ep = Process-weighted mass emissions of PM or total metal
HAP, lb/ton;
C = Concentration of PM or total metal HAP, gr/dscf;
Q = Volumetric flow rate of stack gas, 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
Sec.  63.10895(b) 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.
[GRAPHIC] [TIFF OMITTED] TP17SE07.001

Where:

EC = The mass-weighted PM or total metal HAP emissions
for the group of all metal melting furnaces at the foundry, lb/ton;
Epi = 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,
lb/ton;
Tti = 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, you may assume an emissions factor of 3
pounds per ton of PM or 0.2 pounds per ton 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 Sec.  63.10895(b)
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.
[GRAPHIC] [TIFF OMITTED] TP17SE07.002

Where:

Ei = Mass emissions rate of PM or total metal HAP at the
control device inlet, lb/hr;
Eo = 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:
[GRAPHIC] [TIFF OMITTED] TP17SE07.003

Where:

Ep1released = Calculated process-weighted mass emissions
of PM (or total metal HAP) predicted to be released to the
atmosphere from the regulated emissions source, lb/ton; and
Ep1i = Process-weighted mass emissions of PM (or total
metal HAP) in the uncontrolled regulated exhaust stream, lb/ton.

    (g) To determine compliance with an emissions limit for situations
when multiple sources are controlled by a single control device, but
only one source operates at a time or other situations that are not
expressly considered in paragraphs (d) through (f) of this section, you
must submit a site-

specific test plan to the Administrator for approval according to the
requirements in Sec.  63.7(c)(2) and (3).
    (h) You must conduct each opacity test for fugitive emissions
according to the requirements in Sec.  63.6(h)(5) and Table 1 to this
subpart.
    (i) You must conduct subsequent performance tests to demonstrate
compliance with the opacity limit in Sec.  63.10895(d) no less
frequently than every 6 months and each time you make a process change
likely to increase fugitive emissions.
    (j) In your performance test report, you must certify that the
capture system operated normally during the performance test.
    (k) You must establish operating limits during the initial
performance test according to the requirements in Table 2 of this
