Work Practice Standards

§63.7700  What work practice standards must I meet?

	(a)  For each segregated scrap storage area, bin or pile, you must
comply with the certification requirements in paragraph (b) of this
section, or prepare and implement a plan for the selection and
inspection of scrap according to the requirements in paragraph (c) of
this section.  You may have certain scrap subject to paragraph (b) of
this section and other scrap subject to paragraph (c) of this section at
your facility provided the scrap remains segregated until charge
make-up.

	(b)  You must prepare and operate at all times according to a written
certification that the foundry purchases and uses 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, mercury switches, plastics, or
free organic liquids.  For the purpose of this paragraph (b), “free
organic liquids” is defined as material that fails the paint filter
test by EPA Method 9095A, “Paint Filter Liquids Test” (Revision 1,
December 1996), as published in EPA Publication SW-846 “Test Methods
for Evaluating Solid Waste, Physical/Chemical Methods” (incorporated
by reference – see § 63.14).  Any post-consumer engine blocks,
post-consumer oil filters, or oily turnings that are processed and/or
cleaned to the extent practicable such that the materials do not include
lead components, mercury switches, chlorinated plastics, or free organic
liquids can be included in this certification.

	(c)  You must prepare and operate at all times according to a written
plan for the selection and inspection of iron and steel scrap to
minimize, to the extent practicable, the amount of organics and HAP
metals in the charge materials used by the iron and steel foundry.  This
scrap selection and inspection plan is subject to approval by the
Administrator.  You must keep a copy of the plan onsite and readily
available to all plant personnel with materials acquisition or
inspection duties.  You must provide a copy of the material
specifications to each of your scrap vendors.  Each plan must include
the information specified in paragraphs (c)(1) through (3) of this
section.

	(1)  A materials acquisition program to limit organic contaminants
according to the requirements in paragraph (c)(1)(i) or (ii) of this
section, as applicable.

	(i)  For scrap charged to a scrap preheater, electric arc metal melting
furnace, or electric induction metal melting furnaces, specifications
for scrap materials to be depleted (to the extent practicable) of the
presence of used oil filters, chlorinated plastic parts, organic
liquids, and a program to ensure the scrap materials are drained of free
liquids; or

	(ii)  For scrap charged to a cupola metal melting furnace,
specifications for scrap materials to be depleted (to the extent
practicable) of the presence of chlorinated plastic, and a program to
ensure the scrap materials are drained of free liquids.

	(2)  A materials acquisition program specifying that the scrap supplier
remove accessible mercury switches from the trunks and hoods of any
automotive bodies contained in the scrap and remove accessible lead
components such as batteries and wheel weights.  You must either obtain
and maintain onsite a copy of the procedures used by the scrap supplier
for either removing accessible mercury switches or for purchasing
automobile bodies that have had mercury switches removed, as applicable,
or document your attempts to obtain a copy of these procedures from the
scrap suppliers servicing your area.

	(3)  Procedures for visual inspection of a representative portion, but
not less than 10 percent, of all incoming scrap shipments to ensure the
materials meet the specifications.

	(i)  The inspection procedures must identify the location(s) where
inspections are to be performed for each type of shipment.  Inspections
may be performed at the scrap supplier’s facility.  The selected
location(s) must provide a reasonable vantage point, considering worker
safety, for visual inspection.

	(ii)  The inspection procedures must include recordkeeping requirements
that document each visual inspection and the results.

	(iii)  The inspection procedures must include provisions for rejecting
or returning entire or partial scrap shipments that do not meet
specifications and limiting purchases from vendors whose shipments fail
to meet specifications for more than three inspections in one
calendercalendar year.

	(iv)  If inspections are performed at the scrap supplier’s facility,
the inspection procedures must include an explanation of how the
periodic inspections ensure that not less than 10 percent of scrap
purchased from the supplier is subject to inspection.

	(d)  For each furan warm box mold or core making line in a new or
existing iron and steel foundry, you must use a binder chemical
formulation that does not contain methanol as a specific ingredient of
the catalyst formulation as determined by the Material Safety Data
Sheet.  This requirement does not apply to the resin portion of the
binder system.

	(e)  For each scrap preheater at an existing iron and steel foundry,
you must meet either the requirement in paragraph (e)(1) or (2) of this
section.  As an alternative to the requirement in paragraph (e)(1) or
(2) of this section, you must meet the VOHAP emissions limit in
§63.7690(a)(9).

	(1)  You must install, operate, and maintain a gas-fired preheater
where the flame directly contacts the scrap charged; or

	(2)  You must charge only material that is subject to and in compliance
with the scrap certification requirement in paragraph (b) of this
section.

	(f)  For each scrap preheater at a new iron and steel foundry, you must
charge only material that is subject to and in compliance with the scrap
certification requirement in paragraph (b) of this section.  As an
alternative to this  requirement, you must meet the VOHAP emissions
limit in §63.7690(a)(9).

Operation and Maintenance Requirements

§63.7710  What are my operation and maintenance requirements?

	(a)  As required by §63.6(e)(1)(i), you must always operate and
maintain your iron and steel foundry, including air pollution control
and monitoring equipment, in a manner consistent with good air pollution
control practices for minimizing emissions at least to the levels
required by this subpart.

	(b)  You must prepare and operate at all times according to a written
operation and maintenance plan for each capture and collection system
and control device for an emissions source subject to an PM, metal HAP,
TEA, or VOHAP emissions limit in §63.7690(a).  Your operation and
maintenance plan also must include procedures for igniting gases from
mold vents in pouring areas and pouring stations that use a sand mold
system.  This operation and maintenance plan is subject to approval by
the Administrator.  Each plan must contain the elements described in
paragraphs (b)(1) through (6) of this section.

	(1)  Monthly inspections of the equipment that is important to the
performance of the total capture system (i.e., pressure sensors,
dampers, and damper switches).  This inspection must include
observations of the physical appearance of the equipment (e.g., presence
of holes in the ductwork or hoods, flow constrictions caused by dents or
accumulated dust in the ductwork, and fan erosion).  The operation and
maintenance plan must also include requirements to repair the defect or
deficiency as soon as practicable.

	(2)  Operating limits for each capture system for an emissions source
subject to an emissions limit or standard for VOHAP or TEA in
§63.7690(a)(8) through (11).  You must establish the operating
according to the requirements in paragraphs (b)(2)(i) through (iii) of
this section.

	(i)  Select operating limit parameters appropriate for the capture
system design that are representative and reliable indicators of the
performance of the capture system.  At a minimum, you must use
appropriate operating limit parameters that indicate the level of the
ventilation draft and damper position settings for the capture system
when operating to collect emissions, including revised settings for
seasonal variations.  Appropriate operating limit parameters for
ventilation draft include, but are not limited to:  volumetric flow rate
through each separately ducted hood, total volumetric flow rate at the
inlet to the control device to which the capture system is vented, fan
motor amperage, or static pressure.  Any parameter for damper position
setting may be used that indicates the duct damper position related to
the fully open setting.

	(ii)  For each operating limit parameter selected in paragraph
(b)(2)(i) of this section, designate the value or setting for the
parameter at which the capture system operates during the process
operation.  If your operation allows for more than one process to be
operating simultaneously, designate the value or setting for the
parameter at which the capture system operates during each possible
configuration that you may operate (i.e., the operating limits with one
furnace melting, two melting, as applicable to your plant).

	(iii)  Include documentation in your plan to support your selection of
the operating limits established for your capture system.  This
documentation must include a description of the capture system design, a
description of the capture system operating during production, a
description of each selected operating limit parameter, a rationale for
why you chose the parameter, a description of the method used to monitor
the parameter according to the requirements of §63.7740(a), and the
data used to set the value or setting for the parameter for each of your
process configurations.

	(3)  Preventative maintenance plan for each control device, including a
preventative maintenance schedule that is consistent with the
manufacturer’s instructions for routine and long-term maintenance.

	(4)  A site-specific monitoring plan for each bag leak detection
system.  For each bag leak detection system that operates on the
triboelectric effect, the monitoring plan must be consistent with the
recommendations contained in the U.S. Environmental Protection Agency
guidance document “Fabric Filter Bag Leak Detection Guidance”
(EPA-454/R-98-015).  This baghouse monitoring plan is subject to
approval by the Administrator.  The owner or operator shall operate and
maintain the bag leak detection system according to the site-specific
monitoring plan at all times.  The plan must address all of the items
identified in paragraphs (b)(4)(i) through (v) of this section.

	(i)  Installation of the bag leak detection system.

	(ii)  Initial and periodic adjustment of the bag leak detection system
including how the alarm set-point will be established.

	(iii)  Operation of the bag leak detection system including quality
assurance procedures.

	(iv)  How the bag leak detection system will be maintained including a
routine maintenance schedule and spare parts inventory list.

	(v)  How the bag leak detection system output will be recorded and
stored.

	(5)  Corrective action plan for each baghouse.  The plan must include
the requirement that, in the event 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 the corrective action as soon as practicable.  Corrective
actions taken may include, but are not limited to:

	(i)  Inspecting the baghouse 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.

	(iii)  Replacing defective bags or filter media or otherwise repairing
the control device.

	(iv)  Sealing off a defective baghouse compartment.

	(v)  Cleaning the bag leak detection system probe or otherwise
repairing the bag leak detection system.

	(vi)  Making process changes.

	(vii)  Shutting down the process producing the PM emissions.

	(6)  Procedures for providing an ignition source to mold vents of sand
mold systems in each pouring area and pouring station unless you
determine the mold vent gases either are not ignitable, ignite
automatically, or cannot be ignited due to accessibility or safety
issues.  You must document and maintain records of this determination.
The determination of ignitability, accessibility, and safety may
encompass multiple casting patterns provided the castings utilize
similar sand-to-metal ratios, binder formulations, and coating
materials.  The determination of ignitability must be based on
observations of the mold vents within 5 minutes of pouring, and the
flame must be present for at least 15 seconds for the mold vent to be
considered ignited.  For the purpose of this determination:

	(i)  Mold vents that ignite more than 75 percent of the time without
the presence of an auxiliary ignition source are considered to ignite
automatically; and

	(ii)  Mold vents that do not ignite automatically and cannot be ignited
in the presence of an auxiliary ignition source more than 25 percent of
the time are considered to be not ignitable.

General Compliance Requirements

§63.7720  What are my general requirements for complying with this
subpart?

	(a)  You must be in compliance with the emissions limitations, work
practice standards, and operation and maintenance requirements in this
subpart at all times, except during periods of startup, shutdown, or
malfunction.

	(b)  During the period between the compliance date specified for your
iron and steel foundry in §63.7683 and the date when applicable

	(a)  As required by §63.7(a)(2), you must conduct a performance test
no later than 180 calendar days after the compliance date that is
specified in §63.7683 for your iron and steel foundry to demonstrate
initial compliance with each emissions limitation in §63.7690 that
applies to you.

	(b)  For each work practice standard in §63.7700 and each operation
and maintenance requirement in §63.7710 that applies to you where
initial compliance is not demonstrated using a performance test, you
must demonstrate initial compliance no later than 30 calendar days after
the compliance date that is specified for your iron and steel foundry in
§63.7683.

	(c)  If you commenced construction or reconstruction between December
