and technology exchange in various areas of air pollution control.

C. Judicial Review

     Under section 307(b)(1) of the Clean Air Act (CAA), judicial 
review of these final amendments is available only by filing a petition 
for review in the U.S. Court of Appeals for the District of Columbia 
Circuit by April 7, 2008. Under section 307(d)(7)(B) of the CAA, only 
an objection to these final amendments that was raised with reasonable 
specificity during the period for public comment can be raised during 
judicial review. Moreover, under section 307(b)(2) of the CAA, the 
requirements established by these final amendments may not be 
challenged separately in any civil or criminal proceedings brought by 
EPA to enforce these requirements.

II. Background Information

     The NESHAP for iron and steel foundries (40 CFR part 63, subpart 
EEEEE) establishes emissions limitations and work practice requirements 
for the control of hazardous air pollutants (HAP) from foundry 
operations. The NESHAP implements section 112(d) of the CAA by 
requiring all iron and steel foundries that are major sources of HAP to 
meet standards reflecting application of the maximum achievable control 
technology (MACT). The compliance date for most of the subpart EEEEE 
requirements was April 23, 2007.
    After publication of the NESHAP (69 FR 21906, April 22, 2004), the 
American Foundry Society, the Alliance of Automobile Manufacturers, and 
the Steel Founders' Society of America filed petitions for 
reconsideration of the final rule. The American Foundry Society and the 
Steel Founders' Society of America also filed petitions for review of 
the final rule (Steel Founders' Society of America v. U.S. EPA, No. 04-
1190, DC Cir.) and American Foundry Society v. U.S. EPA, No. 04-1191, 
DC Cir.). The concerns raised by the petitioners regarding the work 
practice standards for scrap management have been resolved by rule 
amendments issued on May 20, 2005 (97 FR 29400). The Steel Founders' 
Society of America petitioned the court for voluntary dismissal of 
their petition for review on March 23, 2006, and the court granted that 
petition on May 2, 2006. Thus, the only challenge to the NESHAP 
remaining before the court is the American Foundry Society petition for 
review, No. 04-1191.
    In accordance with section 113(g) of the CAA, EPA published a 
notice of a proposed settlement agreement between EPA and the 
petitioner (72 FR 1986, January 17, 2007) and provided a 30-day comment 
period which ended on February 16, 2007. The settlement agreement 
became final on March 9, 2007. On April 17, 2007 (72 FR 19150), we 
proposed rule amendments which addressed the need for alternative 
emissions limits for cupolas at existing foundries and clarification of 
other rule requirements as set forth in Attachment A to the settlement 
agreement. The proposed amendments also included corrections to a few 
minor editorial errors.
    These final amendments are materially the same as the proposed 
amendments. EPA expects these final amendments to resolve the remaining 
issues raised by the petitioner.

III. Summary of Final Amendments and Changes Made Since Proposal

     These final amendments include two changes since proposal. The 
first change is in the wording used to describe the emission limit for 
the new compliance option for cupola melting furnaces; instead of 
abbreviating the limit as lb/

[[Page 7212]]

ton of particulate matter (PM) (or total metal HAP), we expressly state 
the limit as pound of PM (or total metal HAP) per ton of metal charged. 
We intend this as a clarification, not as a substantive change from 
what we proposed. We are also correcting a publication error in the 
definition of ``deviation'' as published at 72 FR 19164. All other 
final amendments are exactly as proposed.

A. Emissions Limitations

1. New Compliance Options for Cupola Metal Melting Furnaces
     These final amendments add a new compliance option to Sec.  
73.7690(a)(2) of the NESHAP. The new alternative emissions limits for 
cupola metal melting furnaces at existing iron and steel foundries 
allows the use of control technologies that are designed on a mass 
removal basis rather than an outlet concentration basis. The levels of 
the new alternative emissions limits are the same as proposed: 0.10 
pound of PM per ton of metal charged or 0.008 pound of total HAP per 
ton of metal charged. In response to public comment, we have revised 
the manner in which the emissions limits are stated in the rule for 
clarity. We have also revised associated compliance provisions in 
Sec. Sec.  63.7732(b)(6) and (c)(6), 63.7734(a)(2)(iii) and (iv), and 
63.7743(a)(2)(iii) and (iv) to refer to the new alternative limits in 
terms of pounds of PM per ton (lb/ton) of metal charged or pounds of 
total metal HAP per ton of metal charged instead of lb/ton of PM or lb/
ton of total metal HAP, respectively.
2. Fugitive Emissions Opacity Limit
     These final amendments specify that the opacity limitations apply 
only to buildings that house iron and steel foundry emissions sources. 
If nonfoundry operations are housed in the same building as the foundry 
operations, the foundry must comply with the opacity limits for that 
building.
3. Triethylamine Emissions Limit
     These final amendments replace the reference to test conditions 
(``as determined when scrubbing with fresh acid solution'') with the 
phrase ``according to the performance test procedures in Sec.  
63.7732(g)'' since Sec.  63.7732(g) contains the requirement to conduct 
the test when scrubbing with fresh acid solution.

B. Work Practice Standards

1. Capture and Collection Systems
     These final amendments delete the word ``standard'' from 40 CFR 
63.7690(b)(1) to clarify that capture and collection systems are 
required for emissions sources subject to an emissions limit but not 
for emissions sources subject to work practice standards.
2. Scrap Management
     These final amendments specify that ``chlorinated'' plastics are 
to be removed from the scrap material (instead of all plastic). These 
final amendments also revise the requirement in 40 CFR 63.7700(c)(2) 
for the owner or operator to 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 the 
switches removed. These final amendments include an alternative 
procedure that allows the plant to document their attempts to obtain a 
copy of the procedures from the scrap suppliers servicing their area. 
We note, however, that under 40 CFR 63.7700(c)(2) the materials 
acquisition program must specify that the scrap supplier remove 
accessible mercury switches from the trunks and hoods of any automotive 
bodies contained in the scrap in addition to accessible lead components 
such as batteries and wheel weights. It is incumbent on the foundry 
owner or operator to communicate these specifications to their scrap 
suppliers.
3. Scrap Preheaters
     The existing rule requires the owner or operator to install, 
operate, and maintain a gas-fired preheater according to 40 CFR 
63.7700(e)(1) or charge only certain materials according to 40 CFR 
63.7700(e)(2). These final amendments revise the language of Sec.  
63.7700(e)(1) to clarify that foundries are not required to install 
gas-fired preheaters when not necessary for foundry operations. It was 
not our intent to mandate installation of preheaters, but rather to 
establish requirements for those existing facilities that use scrap 
preheaters in lieu of selecting the option in 40 CFR 63.7700(e)(2). 
Therefore, these final amendments clarify Sec.  63.7700(e)(1) by 
deleting the word ``install''. Instead, these final amendments require 
the owner or operator to operate and maintain a gas-fired preheater 
where the flame directly contacts the scrap charged.

C. Operation and Maintenance Requirements

     These final amendments clarify that the requirement in 40 CFR 
63.7700(e)(2) applies to each capture and collection system and control 
device for an emissions source subject to a PM, metal HAP, 
triethylamine (TEA), or volatile organic hazardous pollutants (VOHAP) 
emissions limit in 40 CFR 63.7690(a).

D. Compliance With Alternative Emissions Limits

    The existing NESHAP establishes PM emissions limits and alternative 
emissions limits expressed in total metal HAP for cupolas and other 
foundry processes. These final amendments clarify our original intent 
to allow foundries to demonstrate compliance with any of the applicable 
alternative emissions limitations that are provided for a specific 
emissions source. When multiple alternative emissions limitations are 
provided for a specific emissions source, iron and steel foundries can 
demonstrate initial compliance with any of the alternative limits; they 
are not required to comply with all of the alternative emissions limits 
at any one time. These final amendments also clarify a facility's 
ability to change their selected compliance alternative and the 
procedures needed to effect that change. However, regarding continuous 
compliance, the facility is expected to continuously comply with the 
alternative emissions limit that was selected as their compliance 
option as demonstrated in their most recent performance test. The 
facility may choose to alter their selected alternative but must 
continue to comply with the previously selected alternative until they 
successfully demonstrate compliance with the new alternative emissions 
limitation.
    We are also finalizing requirements for determining initial 
compliance for cupola melting furnaces at existing iron and steel 
foundries that are subject to the new mass rate emissions limit. The 
final amendments to 40 CFR 63.7732(b) and (c) include new equations for 
determining PM or total metal HAP emissions from cupolas in the lb/ton 
of metal charged format. Other amendments to 40 CFR 63.7732(b) and (c) 
clarify test methods source sampling requirements.
1. Single Performance Test for Control Devices Serving Multiple Units
    Section 63.7734 of the NESHAP requires iron and steel foundries to 
demonstrate initial compliance with PM emissions limits by conducting a 
performance test for each process unit according to the procedures in 
40 CFR 63.7732. One petitioner pointed out that a common emissions 
control system may serve two similar or identical cupolas or serve 
multiple furnaces or process units. According to the petitioner, a 
requirement for separate tests of the control device while the

[[Page 7213]]

emissions sources are operating is redundant and imposes unnecessary 
costs because the control device should perform the same on each 
identical furnace. These final amendments resolve the petitioner's 
concern by adding a new provision to the performance test requirements. 
As proposed, the final amendment requires foundries to submit a site-
specific test plan for the situation described by the petitioner or 
other situations not expressly considered in 40 CFR 63.7734. The site-
specific test plan, which is subject to approval by the Administrator, 
will explain the procedures that would be followed during the test, 
such as operation of the unit or units at the maximum operating 
condition of the control system. The Administrator or delegated 
authority will determine on a case-by-case basis if one representative 
furnace/control device configuration may be tested.
2. Sampling Procedure for Electric Arc Furnaces, Electric Induction 
Furnaces, and Scrap Preheaters
    As proposed, we are clarifying the sampling instructions in 40 CFR 
63.7732(c)(4) and (5) to state that the initial compliance 
demonstrations for electric arc metal melting furnaces, electric 
induction metal melting furnaces, and scrap preheaters must be 
conducted under normal production conditions. These final amendments 
require sampling during normal operating conditions, which may include 
charging, melting, alloying, refining, slagging, and tapping (for a 
furnace) or charging, heating, and discharging (for a scrap preheater).
3. Minimum Sampling Volume for Total Metal HAP
    As proposed, these final amendments remove the requirement in 40 
CFR 63.7732(c)(2) for a minimum sample volume for test runs by EPA 
Method 29 (40 CFR part 60, appendix A) because the method already 
includes such a requirement.
4. Opacity Test
    Section 63.7732(d) of the existing NESHAP establishes the 
requirements for opacity tests. These final amendments instruct the 
certified observer how to take opacity readings by Method 9 (40 CFR 
part 60, appendix A) for a building that has many openings. As 
proposed, these final amendments allow the observer to take readings 
from a limited number of openings or vents that appear to have the 
highest opacities instead of making observations for each opening or 
vent from the building or structure. Alternatively, a single 
observation for the entire building is allowed if the fugitive release 
points afford such an observation. These final amendments also revise 
the language of 40 CFR 63.7732(d)(2) to clarify that opacity tests are 
to be conducted during PM performance tests, but that PM performance 
tests are not required to occur during the semiannual opacity tests.
5. Alternative Test Method
    Section 63.7732(g)(v) of the existing NESHAP requires the use of 
EPA Method 18 (40 CFR part 60, appendix A) to determine the TEA 
concentration of gases from the TEA cold box mold or core-making line. 
As proposed, these final amendments allow NIOSH Method 2010, ``Amines, 
Aliphatic'' (incorporated by reference--see Sec.  63.14) as an 
alternative to EPA Method 18 (40 CFR part 60, appendix A) provided the 
performance requirements outlined in section 13.1 of EPA Method 18 are 
satisfied. Method 2010 is included in the NIOSH Manual of Analytical 
Methods (4th edition, NIOSH Publication 94-113, August 1994). The 
manual is available from the Government Printing Office and the 
National Technical Information Service (NTIS), NTIS publication No. 
PB95154191. The NIOSH method may also be found on the NIOSH Web site at 
the following address: http://www.cdc.gov/niosh/nmam/method-4000.html.

6. Procedures for Establishing Operating Limits
    As proposed, these final amendments clarify the procedures for 
establishing control device operating limits in 40 CFR 63.7733(b) 
through (d) by deleting the reference to the 3-hour average from the 
test procedures. These final amendments specify that the owner or 
operator is to compute and record the average operating parameter value 
for each valid sampling run in which the applicable limit is met.
7. Repeat Performance Tests
    As proposed, these final amendments revise the requirements for 
repeat performance in 40 CFR 63.7731(a) to clarify that demonstrating 
compliance by one method does not preclude a plant from demonstrating 
compliance using an alternative method at a later date. A plant may 
elect to demonstrate compliance with an alternative emissions limit 
during the repeat performance tests conducted at least every 5 years. 
Furthermore, a plant may elect to conduct a performance test earlier 
than 5 years in order to change an operating limit or to demonstrate 
compliance with a different alternative emissions limit. A test 
conducted for the purpose of changing operating limits is subject to 
notification requirements in 40 CFR 63.7750(d).

E. Monitoring Requirements

1. Baghouse Monitoring Requirements
    Section 63.7740(b) of the existing NESHAP requires a bag leak 
detection system for each negative pressure baghouse and for each 
positive pressure baghouse equipped with a stack where the baghouse is 
applied to meet any PM or total metal HAP emissions limitation in 
subpart EEEEE. This provision also requires inspection of each baghouse 
according to the requirements in 40 CFR 63.7740(b)(1) through (8). As 
proposed, these final amendments include monitoring requirements for 
the visual inspection of positive pressure baghouses that are not 
equipped with a stack. As proposed, these final amendments to 40 CFR 
63.7740(b) clarify the text to ensure that the requirements in this 
paragraph for installing and using a bag leak detection system apply 
only to negative pressure baghouses and positive pressure baghouses 
equipped with a stack. The inspection requirements are separated and 
placed in a new paragraph (c) and clarified to state that the 
inspection requirements apply to each baghouse regardless of type. 
These final amendments to 40 CFR 63.7740 also renumber the paragraphs 
which follow new paragraph (c). Similar clarifications are made to the 
requirements for demonstrating continuous compliance in 40 CFR 
63.7743(c).
2. Demonstration of Initial Compliance With Bag Leak Detection System 
Operation and Maintenance Requirements
    Section 63.7736(c) of the existing NESHAP instructs the owner or 
operator how to demonstrate initial compliance with the requirements 
for bag leak detection systems. Under 40 CFR 63.7736(c)(1), the owner 
or operator must submit the bag leak detection system monitoring plan 
to the Administrator for approval according to the requirements in 40 
CFR 63.7710(b). As proposed, these final amendments to 40 CFR 
63.7736(c)(1) revise this provision to clarify that submission of the 
monitoring plan independent of the operation and maintenance plan is 
not necessary. Our intent is to include the bag leak detection system 
information in the operation and maintenance plan to streamline the 
approval process and avoid the administrative costs associated with a 
separate submission.

[[Page 7214]]

In addition, having one integrated plan will provide a centralized 
reference tool for control device operation and maintenance 
requirements.
3. Installation, Operation, and Maintenance Requirements for Monitors
    As proposed, these final amendments revise the requirements for 
operation and maintenance of continuous parameter monitoring systems to 
more clearly describe the inspection requirements. Under the operation 
and maintenance requirements for flow measurement devices in 40 CFR 
63.7741(a)(1)(iv), the owner or operator must perform monthly 
inspections of all flow sensor components for integrity, all electrical 
connections for continuity, and all mechanical connections for leakage. 
These final amendments change this provision to require a monthly 
visual inspection of all components, including all electrical and 
mechanical connections for proper functioning. The same changes are 
made to the monthly inspection requirements for other types of 
monitoring devices in Sec. Sec.  63.7741(a)(2)(vi), (c)(1)(vi), 
(c)(2)(iv), (d)(8), and (e)(2)(iv).
    As proposed, these final amendments also revise the requirement for 
pressure measurement devices in 40 CFR 63.7741(a)(2)(iii) and 40 CFR 
63.7741(c)(1)(iv) for a ``daily check of the pressure tap for 
pluggage.'' We are requiring a daily check for pluggage when using a 
regular pressure tap and a monthly check when using a non-clogging 
pressure tap. These final amendments also clarify the requirements for 
pressure measurement devices in 40 CFR 63.7741(a)(2)(iv) and 40 CFR 
63.7741(c)(1)(iv) to allow the use of a manometer or equivalent device 
for calibrations.

F. Recordkeeping and Reporting Requirements

    As proposed, these final amendments clarify two of the 
recordkeeping requirements in 40 CFR 63.7752(a)(4). The requirement for 
the annual quantity of chemical binder or coating materials used to 
make molds and cores is revised to require the annual quantity of 
chemical binder or coating materials used to coat or make molds and 
cores. (We inadvertently omitted the word ``coat'' from the original 
rule language.) The final requirement for records of the annual 
quantity of HAP used states that records are required of the annual 
quantity of HAP used in these chemical binder or coating materials at 
the foundry, as calculated from the recorded quantities and chemical 
compositions (from Material Data Safety Sheet or other documentation). 
This final amendment clarifies that the HAP records requirement is 
specific to the chemicals used in the mold and core-making and coating 
operations and not to other HAP materials used at the foundry such as 
solvents used to clean or degrease equipment.
    These final amendments to the reporting requirements allow 
foundries to report the results of the semiannual opacity tests within 
the semiannual reports rather than having to submit these semiannual 
documents separately. Other final amendments to the reporting 
requirements clarify the requirements for an immediate startup, 
shutdown, and malfunction report by adding the same language used in 40 
CFR 63.10(d)(5)(ii). These final amendments require an immediate report 
if a foundry has a startup, shutdown, or malfunction and exceeds any 
applicable emissions limitation in 40 CFR 63.7690.

G. Definitions

    We are amending the definition of the term ``Deviation'' in 40 CFR 
63.7765 to clarify that the enforcement authority determines if a 
deviation is a violation. The proposed amendment appeared at 72 FR 
19164: however, due to a publication error, the new language was added 
after the first sentence of the original definition, rather than at the 
end. In these final amendments, we are correcting the placement of the 
new language.
    As proposed, we are adding definitions of the terms ``off blast'' 
and ``on blast'' to 40 CFR 63.7765. The term ``off blast'' is defined 
as those periods of cupola operation when the cupola is not actively 
being used to produce molten metal. Off-blast conditions include cupola 
startup procedures as defined in the startup, shutdown, and malfunction 
plan. Off-blast conditions also include idling conditions when the 
blast air is turned off or down to the point that the cupola does not 
produce additional molten metal. The term ``on blast'' means those 
periods of cupola operation when combustion (blast) air is introduced 
to the cupola furnace and the furnace is capable of producing molten 
metal. On blast conditions are characterized by both blast air 
introduction and molten metal production.
    As proposed, these final amendments revise the definition of 
``total metal HAP'' to specify the analytes to be included and how non-
detect values are to be used in calculating the total metal HAP 
quantity. The definition of ``total metal HAP'' is the sum of the 
concentrations of antimony, arsenic, beryllium, cadmium, chromium, 
cobalt, lead, manganese, mercury, nickel, and selenium as measured by 
EPA Method 29 (40 CFR part 60, appendix A). Only the measured 
concentration of the listed analytes that are present at concentrations 
exceeding one-half of the quantification limit of the analytical method 
are used in the sum. If any of the analytes are not detected or are 
detected at concentrations less than one-half the quantification limit 
of the analytical method, the concentration of those analytes is 
assumed to be zero for the purposes of calculating the total metal HAP 
for this subpart.
    As proposed, we are also clarifying the definition of ``scrap 
preheater'' to differentiate scrap dryers that are used solely to 
remove moisture from the scrap metal from scrap preheaters. The revised 
definition of ``scrap preheater'' states that scrap dryers, which are 
used solely to remove water from metal scrap that does not contain any 
volatile impurities or other tramp materials, are not considered to be 
scrap preheaters for purposes of this subpart.

H. Applicability

    As proposed, we are revising the applicability provisions in 40 CFR 
63.7681 to reference the definition of ``major source'' in 40 CFR 63.2. 
This amendment clarifies that when we refer to a ``major source'' of 
hazardous air pollutants in 40 CFR 63.7681, we are referring to the 
definition of major source in 40 CFR 63.2, and not, for example, to the 
definition of major source in 40 CFR 51.166.

I. Editorial Corrections

    As proposed, we are correcting a grammatical error in 40 CFR 
63.7710(b), which should refer to an emissions source subject to a 
(rather than ``an'') PM, metal HAP, TEA, or VOHAP emissions limit in 40 
CFR 63.7690(a). A comma is added to 40 CFR 63.7734(a)(11). The words 
``as possible'' are added to 40 CFR 63.7741(a)(2)(i). The final 
amendments also correct a misspelling of the word ``calendar'' in 40 
CFR 63.7700(c)(3)(iii).

IV. Summary of Comments and Responses

A. Language of Proposed Alternative Emissions Limits

    Comment: One commenter expressed support for the proposed 
alternative standards for PM or total metal HAP and conforming 
amendments. However, the commenter believed that the wording of the 
proposed limit for total metal HAP is ambiguous even though the meaning 
is clear in context. According to the commenter, the proposed limit for 
total metal HAP (0.008 lb/ton of total metal

[[Page 7215]]

HAP) could be construed to mean that the standard is 0.008 pounds of 
some unspecified substance per ton of total metal HAP emitted. The 
commenter recommended that EPA clarify the language to read ``0.008 
pounds of total metal HAP per ton (lb/ton) of metal charged'' which 
would be consistent with the language in Sec.  63.7690(a)(ii) for the 
proposed alternative PM limit.
    Response: Section 63.7690(a)(2)(ii) of the proposed amendments 
establishes the alternative limit for PM as 0.10 pound of PM per ton 
(lb/ton) of metal charged; the lb/ton abbreviation is then used in 
Sec.  63.7690(a)(2)(iv) for the total metal HAP limit. While we agree 
with the commenter that the meaning is clear in context, we have 
revised the language for the total metal HAP limit to read according to 
the commenter's suggestion. For additional clarity, we have revised the 
wording of both limits when they appear in conforming amendments to 
read ``pound of PM per ton (lb/ton) of metal charged'' and ``pound of 
total metal HAP per ton (lb/ton) of metal charged.''

B. Mercury Emissions Limit

    Comment: One commenter recommended that EPA adopt stand-alone 
mercury emissions standards similar to those in New Jersey.\1\ The 
commenter explained that the rule requires iron and steel melters (at 
both foundries and steel production plants) to meet a mercury emissions 
limit of 35 milligrams per ton (mg/ton) of steel produced or, in the 
alternative, reduce mercury emissions by 75 percent using a mercury 
control apparatus. The emission limit, which becomes effective in 
January 2010, can be achieved through source separation measures and, 
if necessary, additional exhaust controls. According to the commenter, 
the emissions limit determines the success of the source separation 
program and the need for add-on mercury control measures on the melter 
exhaust. The commenter stated that one foundry had recently installed 
an activated carbon injection system for mercury control and a baghouse 
serving the cupola and that test results show greater than 90 percent 
mercury control and emissions less than 3 mg/ton. According to the 
commenter, other facilities with existing fabric filter control are 
testing carbon injection and have reported compliance with the mercury 
emissions limit but have not submitted formal test results.
---------------------------------------------------------------------------

    \1\ The State of New Jersey Department of Environmental 
Protection mercury regulations for iron and steel scrap melting 
specify that mercury emissions from each melter shall not exceed 35 
megagrams per ton of steel produced. Alternatively, mercury 
emissions as measured at the exit of the mercury control apparatus 
must be reduced by at least 75 percent (N.J.A.C. 7:27-27.6). These 
rules have been upheld by the Appellate Division of the State 
Superior Court.
---------------------------------------------------------------------------

    Response: As described in the preamble to the final NESHAP for Iron 
and Steel Foundries (69 FR 21906, April 22, 2004), the control systems 
used at iron and steel foundries at the time the NESHAP was developed 
were not effective in reducing mercury emissions. The pollution 
prevention measure of removing mercury switches from automotive scrap 
was determined to be a cost-effective ``beyond the MACT floor'' 
requirement and was included as a requirement in the final NESHAP as 
part of the scrap selection and inspection program. The final NESHAP 
was projected to reduce mercury emissions by 2,800 pounds per year at a 
cost of $3.6 million per year (which includes increased cost of scrap 
for removing the mercury switches). We recognize that there are other 
mercury-containing devices in automotive scrap so that the pollution 
prevention program required by the final NESHAP does not eliminate all 
mercury from the scrap. At the time the NESHAP was developed, we 
considered requirements for more stringent mercury reduction 
requirements, either through additional scrap inspection and selection 
inspection requirements specific to other mercury-containing devices or 
through innovative mercury controls. Based on the small quantities of 
mercury in these other devices, these options were determined to be 
cost-ineffective.
    A re-evalulation of the MACT floor for the Iron and Steel NESHAP in 
light of new control systems added to iron and steel foundries since 
the NESHAP was first promulgated is outside the scope of the current 
package of amendments. We did not include or take comment on a separate 
mercury limit in our April 17, 2007 Notice of Proposed Rulemaking. 
Therefore, we are not including specific emission limits for mercury in 
the final amendments. A technology review of the MACT standards is 
required by the CAA eight years after promulgation. These newly 
installed mercury controls will be considered in detail during this 
technology review.

C. Information on Mercury Switch Removal From Scrap Suppliers

    Comment: One commenter stated that EPA should not revise Sec.  
63.7700(b)(2) to eliminate the requirement that facilities buy scrap 
only from suppliers willing to provide a copy of their procedures for 
ensuring that mercury switches are removed from automobile bodies that 
they supply. The commenter believed that no supplier will do this 
unless foundries require it because suppliers that do provide a copy of 
their procedures will be at a disadvantage to suppliers that either do 
not remove the mercury switches or are unwilling to document their 
removal procedures. According to the commenter, under the proposed 
amendments, suppliers would not be penalized as they are under the 
existing rule.
    The commenter stated that this proposed amendment increases mercury 
emissions and that EPA did not provide an estimate of the health, 
environmental, and economic impacts of the increase. The commenter also 
claimed that because of limitations currently enforced on some sources, 
the proposed amendment reduces the stringency of the rule below the 
MACT floor for new sources and possibly for existing sources. According 
to the commenter, the proposed amendment is inconsistent with the CAA.
    Response: The amendment does not absolve the iron and steel foundry 
from the responsibility to use automotive scrap that has had accessible 
mercury switches removed. In previous amendments to the NESHAP (70 FR 
29400, May 20, 2005), we included provisions for foundries to perform 
inspections at the scrap supplier. Thus, the foundry should be able to 
verify whether the supplier in fact removes accessible mercury 
switches. The reason for the amendment is to clarify that EPA is not 
imposing a regulatory burden on the scrap supplier through this rule. 
EPA is not requiring scrap suppliers to provide the foundry with 
written procedures for ensuring the mercury switches are removed. 
Nevertheless, because we require foundries to purchase only automotive 
scrap that has had accessible mercury switches removed from the trunks 
and hoods of automobile bodies, a foundry is much more likely to do 
business with a scrap supplier that supplies written procedures than 
with one that does not. It is incumbent on the foundry to document 
their attempt to obtain written procedures and to ensure, through site 
inspections or other means, that any automotive scrap that they 
purchase from their suppliers has had accessible mercury switches 
removed from the trunks and hoods.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

    This action is not a ``significant regulatory action'' under the 
terms of Executive Order 12866 (58 FR 51735,

[[Page 7216]]

October 4, 1993) and is therefore not subject to review under the 
Executive Order.

B. Paperwork Reduction Act

    This action does not impose any new information collection burden. 
These final amendments add a new compliance alternative, allow a new 
alternative test method, and clarify requirements in the existing rule. 
One amendment to the baghouse monitoring requirements clarifies our 
original intent to require inspections of positive pressure baghouses 
not equipped with a stack. No new burden is associated with this 
requirement because the burden was included in the approved information 
collection request (ICR) for the existing rule. However, the Office of 
Management and Budget (OMB) has previously approved the information 
collection requirements contained in the existing regulation (40 CFR 
part 63, subpart EEEEE) under the provisions of the Paperwork Reduction 
Act, 44 U.S.C. 3501, et seq. and has assigned OMB control number 2060-
0543, EPA ICR number 2096.03. A copy of the OMB-approved ICR may be 
obtained from Susan Auby, Collection Strategies Division, U.S. EPA 
(2822T), 1200 Pennsylvania Ave., NW., Washington, DC 20460, by e-mail 
at auby.susan@epa.gov, or by calling (202) 566-1672.
    Burden means the total time, effort, or financial resources 
expended by persons to generate, maintain, retain, disclose, or provide 
information to or for a Federal agency. This includes the time needed 
to review instructions; develop, acquire, install, and utilize 
technology and systems for the purposes of collecting, validating, and 
verifying information, processing and maintaining information, and 
disclosing and providing information; adjust the existing ways to 
comply with any previously applicable instructions and requirements; 
train personnel to be able to respond to a collection of information; 
search data sources; complete and review the collection of information; 
and transmit or otherwise disclose the information.
    An agency may not conduct or sponsor, and a person is not required 
to respond to, a collection of information unless it displays a 
currently valid OMB control number. The OMB control numbers for EPA's 
regulations in 40 CFR part 63 are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

    The Regulatory Flexibility Act generally requires an agency to 
prepare a regulatory flexibility analysis of any rule subject to notice 
and comment rulemaking requirements under the Administrative Procedure 
Act or any other statute unless the agency certifies that the rule 
would not have a significant economic impact on a substantial number of 
small entities. Small entities include small businesses, small not-for-
profit enterprises, and small governmental jurisdictions.
    For the purposes of assessing the impacts of these final amendments 
on small entities, small entity is defined as: (1) A small business 
that meets the Small Business Administration size standards for small 
businesses found at 13 CFR 121.201 (less than 500 employees for NAICS 
codes 331511, 331512, and 331513); (2) a small governmental 
jurisdiction that is a government of a city, county, town, school 
district, or special district with a population of less than 50,000; 
and (3) a small organization that is any not-for-profit enterprise 
which is independently owned and operated and is not dominant in its 
field.
    After considering the economic impacts of these final amendments on 
small entities, I certify that this action will not have a significant 
economic impact on a substantial number of small entities. In 
determining whether a rule has a significant economic impact on a 
substantial number of small entities, the impact of concern is any 
significant adverse economic impact on small entities, since the 
primary purpose of the regulatory flexibility analyses is to identify 
and address regulatory alternatives ``which minimize any significant 
economic impact of the rule on small entities.'' 5 U.S.C. 603 and 604. 
Thus, an agency may certify that a rule will not have a significant 
economic impact on a substantial number of small entities if the rule 
relieves regulatory burden, or otherwise has a positive economic effect 
on all of the small entities subject to the rule.
    There would not be any adverse impacts on any source (including any 
small entity) as a result of the final amendments because the final 
amendments do not create any new requirements or burdens that were not 
already included in the economic impact assessment for the existing 
rule. These final amendments relieve regulatory burden for all entities 
as a result of the operational flexibility afforded by the alternative 
compliance option, alternative test method, and provisions allowing 
plants to combine multiple reports into a single submission. We have 
therefore concluded that these final amendments will relieve regulatory 
burden for all affected small entities.

D. Unfunded Mandates Reform Act

    Title II of the Unfunded Mandates Reform Act of 1995 (UMRA), Public 
Law 104-4, establishes requirements for Federal agencies to assess the 
effects of their regulatory actions on State, local, and tribal 
governments and the private sector. Under section 202 of the UMRA, EPA 
generally must prepare a written statement, including a cost-benefit 
analysis, for proposed and final rules with ``Federal mandates'' that 
may result in expenditures by State, local, and tribal governments, in 
the aggregate, or by the private sector, of $100 million or more in any 
one year. Before promulgating an EPA rule for which a written statement 
is needed, section 205 of the UMRA generally requires EPA to identify 
and consider a reasonable number of regulatory alternatives and adopt 
the least costly, most cost-effective, or least burdensome alternative 
that achieves the objectives of the rule. The provisions of section 205 
do not apply when they are inconsistent with applicable law. Moreover, 
section 205 allows EPA to adopt an alternative other than the least 
costly, most cost-effective, or least burdensome alternative if the 
Administrator publishes with the final rule an explanation why that 
alternative was not adopted. Before EPA establishes any regulatory 
requirements that may significantly or uniquely affect small 
governments, including tribal governments, it must have developed under 
section 203 of the UMRA a small government agency plan. The plan must 
provide for notifying potentially affected small governments, enabling 
officials of affected small governments to have meaningful and timely 
input in the development of EPA regulatory proposals with significant 
Federal intergovernmental mandates, and informing, educating, and 
advising small governments on compliance with the regulatory 
requirements.
    EPA has determined that these final amendments do not contain a 
Federal mandate that may result in expenditures of $100 million or more 
for State, local, and tribal governments, in the aggregate, or the 
private sector in any one year. The final amendments are expected to 
result in an overall reduction in expenditures for the private sector 
and are not expected to impact State, local, or tribal governments. 
Thus, the final amendments are not subject to the requirements of 
sections 202 and 205 of the UMRA. EPA has determined that these final 
amendments contain no regulatory requirements that might significantly 
or uniquely affect small governments. These final amendments

[[Page 7217]]

contain no requirements that apply to such governments, and impose no 
obligations upon them.

E. Executive Order 13132: Federalism

    Executive Order 13132 (64 FR 43255, August 10, 1999) requires EPA 
to develop an accountable process to ensure ``meaningful and timely 
input by State and local officials in the development of regulatory 
policies that have federalism implications.'' ``Policies that have 
federalism implications'' are defined in the Executive Order to include 
regulations that have ``substantial direct effects on the States, on 
the relationship between the national government and the States, or on 
the distribution of power and responsibilities among the various levels 
of government.''
    These final amendments do not have federalism implications. They 
will not have substantial direct effects on the States, on the 
relationship between the national government and the States, or on the 
distribution of power and responsibilities among the various levels of 
government, as specified in Executive Order 13132. These final 
amendments do not impose any requirements on State and local 
governments. Thus, Executive Order 13132 does not apply to these final 
amendments.

F. Executive Order 13175: Consultation and Coordination With Indian 
Tribal Governments

    Executive Order 13175 (65 FR 67249, November 6, 2000), requires EPA 
to develop an accountable process to ensure ``meaningful and timely 
input by tribal officials in the development of regulatory policies 
that have tribal implications.'' These final amendments do not have 
tribal implications, as specified in Executive Order 13175. These final 
amendments impose no requirements on tribal governments. Thus, 
Executive Order 13175 does not apply to these final amendments.

G. Executive Order 13045: Protection of Children From Environmental 
Health and Safety Risks

    Executive Order 13045, ``Protection of Children from Environmental 
Health Risks and Safety Risks'' (62 FR 19885, April 23, 1997) applies 
to any rule that: (1) Is determined to be ``economically significant'' 
as defined under Executive Order 12866, and (2) concerns an 
environmental health or safety risk that EPA has reason to believe may 
have a disproportionate effect on children. If the regulatory action 
meets both criteria, EPA must evaluate the environmental health or 
safety effects of the planned rule on children, and explain why the 
planned regulation is preferable to other potentially effective and 
reasonably feasible alternatives considered by the Agency.
    EPA interprets Executive Order 13045 as applying only to those 
regulatory actions that are based on health or safety risks, such that 
the analysis required under section 5-501 of the Executive Order has 
the potential to influence the regulation. These final amendments are 
not subject to Executive Order 13045 because they are based on 
technology performance and not on health or safety risks.

H. Executive Order 13211: Actions That Significantly Affect Energy 
Supply, Distribution, or Use

    These final amendments are not subject to Executive Order 13211, 
``Actions Concerning Regulations That Significantly Affect Energy 
Supply, Distribution, or Use'' (66 FR 28355, May 22, 2001) because they 
are not a significant regulatory action under Executive Order 12866.

I. National Technology Transfer Advancement Act

    As noted in the proposed rule, Section 12(d) of the National 
Technology Transfer and Advancement Act (NTTAA) of 1995 (Pub. L. 104-
113, Section 12(d), 15 U.S.C. 272 note) directs EPA to use voluntary 
consensus standards (VCS) in its regulatory activities, unless to do so 
would be inconsistent with applicable law or otherwise impractical. The 
VCS are technical standards (e.g., materials specifications, test 
methods, sampling procedures, and business practices) that are 
developed or adopted by VCS bodies. The NTTAA directs EPA to provide 
Congress, through OMB, explanations when the Agency does not use 
available and applicable VCS.
    These final amendments involve technical standards. Therefore the 
Agency conducted a search to identify potential VCS in addition to the 
EPA and alternative method. However, we identified no such standards 
and none were brought to our attention in comments. Therefore EPA has 
decided to use an alternative methodology, the NIOSH Method 2010, 
``Amines, Aliphatic'' (incorporated by reference in Sec.  63.14) for 
EPA Method 18 (40 CFR part 60, appendix A) to determine the TEA 
concentration of gases from the TEA cold box mold or core making line 
provided the performance requirements outlined in section 13.1 of EPA 
Method 18 are satisfied.
    For the methods required or referenced by these final amendments, a 
source may apply to EPA for permission to use alternative test methods 
or alternative monitoring requirements in place of any required testing 
methods, performance specifications, or procedures under Sec. Sec.  
63.7(f) and 63.8(f) of subpart A of the General Provisions.

J. Executive Order 12898: Federal Actions To Address Environmental 
Justice in Minority Populations and Low-Income Populations

    Executive Order 12898 (59 FR 7629, February 16, 1994) establishes 
Federal executive policy on environmental justice. Its main provision 
directs Federal agencies, to the greatest extent practicable and 
permitted by law, to make environmental justice part of their mission 
by identifying and addressing, as appropriate, disproportionately high 
and adverse human health or environmental effects of their programs, 
policies, and activities on minority populations and low-income 
populations in the United States.
    EPA has determined that these final amendments will not have 
disproportionately high and adverse human health or environmental 
effects on minority or low-income populations because they do not 
affect the level of protection provided to human health or the 
environment. These final amendments do not relax the control measures 
on sources regulated by the rule and therefore will not cause emissions 
increases from these sources.

K. Congressional Review Act

    The Congressional Review Act, 5 U.S.C. 801, et seq., as added by 
the Small Business Regulatory Enforcement Fairness Act of 1996, 
generally provides that before a rule may take effect the agency 
promulgating the rule must submit a rule report, which includes a copy 
of the rule, to each House of Congress and to the Comptroller General 
of the United States. EPA will submit a report containing these final 
amendments and other required information to the U.S. Senate, the U.S. 
House of Representatives, and the Comptroller General of the United 
States prior to publication of the final amendments in the Federal 
Register. A major rule cannot take effect until 60 days after it is 
published in the Federal Register. This action is not a ``major rule'' 
as defined by 5 U.S.C. 804(2). These final amendments will be effective 
on February 7, 2008.

    Deviation means any instance in which an affected source or an 
owner or operator of such an affected source:
    (1) Fails to meet any requirement or obligation established by this 
subpart

[[Page 7223]]

including, but not limited to, any emissions limitation (including 
operating limits), work practice standard, or operation and maintenance 
requirement;
    (2) Fails to meet any term or condition that is adopted to 
implement an applicable requirement in this subpart and that is 
included in the operating permit for any iron and steel foundry 
required to obtain such a permit; or
    (3) Fails to meet any emissions limitation (including operating 
limits) or work practice standard in this subpart during startup, 
shutdown, or malfunction, regardless of whether or not such failure is 
permitted by this subpart.
    A deviation is not always a violation. The determination of whether 
a deviation constitutes a violation of the standard is up to the 
discretion of the entity responsible for enforcement of the standards.
* * * * *
    Off blast means those periods of cupola operation when the cupola 
is not actively being used to produce molten metal. Off blast 
conditions include cupola startup when air is introduced to the cupola 
to preheat the sand bed and other cupola startup procedures as defined 
in the startup, shutdown, and malfunction plan. Off blast conditions 
also include idling conditions when the blast air is turned off or down 
to the point that the cupola does not produce additional molten metal.
    On blast means those periods of cupola operation when combustion 
(blast) air is introduced to the cupola furnace and the furnace is 
capable of producing molten metal. On blast conditions are 
characterized by both blast air introduction and molten metal 
production.
    Scrap preheater means a vessel or other piece of equipment in which 
metal scrap that is to be used as melting furnace feed is heated to a 
temperature high enough to eliminate volatile impurities or other tramp 
materials by direct flame heating or similar means of heating. Scrap 
dryers, which solely remove moisture from metal scrap, are not 
considered to be scrap preheaters for purposes of this subpart.
    Total metal HAP means, for the purposes of this subpart, the sum of 
the concentrations of antimony, arsenic, beryllium, cadmium, chromium, 
cobalt, lead, manganese, mercury, nickel, and selenium as measured by 
EPA Method 29 (40 CFR part 60, appendix A). Only the measured 
concentration of the listed analytes that are present at concentrations 
exceeding one-half the quantitation limit of the analytical method are 
to be used in the sum. If any of the analytes are not detected or are 
detected at concentrations less than one-half the quantitation limit of 
the analytical method, the concentration of those analytes will be 
assumed to be zero for the purposes of calculating the total metal HAP 
for this subpart.
