\1\ North American Industry Classification System (NAICS) code.
Representative industrial codes at which site remediation activities
have been or are currently conducted at some but not all facilities
under a given code. The list is not necessarily comprehensive as to
the types of facilities at which a site remediation cleanup may
potentially be required either now or in the future.
This table is not intended to be exhaustive, but rather provides a
guide for readers regarding entities likely to be regulated by this
action. This table lists the types of entities that we are now aware
could potentially be regulated by this action.
A comprehensive list of NAICS codes cannot be compiled for
businesses or facilities potentially regulated by the rule due to the
nature of activities regulated by the source category. The industrial
code alone for a given facility does not determine whether the facility
is or is not potentially subject to this final rule. This final rule
may be applicable to any type of business or facility at which a site
remediation is conducted to clean up media contaminated with organic
hazardous air pollutant (HAP) and other hazardous material. Thus, for
many businesses and facilities subject to the rule, the regulated
sources (i.e., the site remediation activities) are not the predominant
activity, process, operation, or service conducted at the facility. In
these cases, the industrial code indicates a primary product produced
or service provided at the facility rather than the presence of a site
remediation at the facility. For example, NAICS code classifications
where site remediation activities are currently being performed at some
but not all facilities include, but are not limited to, petroleum
refineries (NAICS code 32411), industrial organic chemical
manufacturing (NAICS code 3251xx), and plastic materials and synthetics
manufacturing (NAICS code 3252xx).
However, we are also aware of site remediation activities
potentially subject to the rule being performed at facilities listed
under NAICS codes for refuse systems, waste management, business
services, miscellaneous services, and nonclassifiable.
To determine whether your facility is regulated by the action, you
should carefully examine the applicability criteria in the 40 CFR part
63, subpart GGGGG-National Emissions Standards for Hazardous Air
Pollutants: Site Remediation. If you have questions regarding the
applicability of this action to a particular entity, consult the person
listed in the preceding FOR FURTHER INFORMATION CONTACT section.

Columbia Circuit by January 29, 2007. Under section 307(d)(7)(B) of the
CAA, only an objection to the final rule 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

I. Background
On October 8, 2003 (68 FR 58172), we issued a NESHAP for site
remediation activities (40 CFR part 63, subpart GGGGG). This NESHAP
implements section 112(d) of the CAA by requiring owners and operators
of facilities that are major sources of HAP emissions and where a site
remediation is conducted, that meets the definitions and conditions
specified in this rule, to comply with emission standards and work
practices for control of HAP reflecting application of the maximum
achievable control technology.
After promulgation of subpart 40 CFR part 63, GGGGG, we received
questions about our intent and interpretation of specific provisions in
the rule. To clarify these issues, we decided that technical amendments
to the rule are appropriate. We proposed on May 1, 2006, (71 FR 25531)
amendments to subpart GGGGG to clarify certain provisions of the rule
and to correct unintentional technical omissions and terminology,
typographical, printing, and grammatical errors that we have identified
since promulgation of the original rule. A 60-day period, which ended
on June 30, 2006, was provided to accept public comments on the
proposed amendments to subpart GGGGG. We received comments on the
proposed amendments from 12 commenters.
A petition for reconsideration for 40 CFR part, subpart GGGGG was
filed by the Sierra Club on December 8, 2003. The amendments to subpart
GGGGG promulgated by this action do not address any issues cited in the
Sierra Club's petition. We are still reviewing the items for
reconsideration and will address them in a future notice.
II. Final Amendments to Rule
We are amending 40 CFR part 63, subpart GGGGG to clarify our intent
for applying and implementing specific rule requirements and to correct
unintentional technical omissions and editorial errors. This action
promulgates our proposed regulatory language for the amendments to
subpart GGGGG except
[[Page 69013]]
for those provisions, as noted below, for which modifications were made
to the regulatory language for the final amendments in response to
specific public comments. Our original projections for the subpart
GGGGG compliance costs, environmental benefits, burden on industry, or
the number of affected facilities are not changed by these final
amendments.
This final rule promulgated by this action reflects our full
consideration of all the comments we received on the amendment
proposal. Our responses to all of the substantive public comments on
the proposal are presented in a comment summary and response document
available in Docket ID No. EPA-HQ-OAR-2002-0021 and at http://www.epa.gov/ttn/atw/siterm/sitermpg.html.
A. Applicability Determination for Remediation Activities at Certain
Oil and Natural Gas Production Facilities
The major source determination requirements used for determining
the applicability of 40 CFR part 63, subpart GGGGG are amended for
certain facilities involved with oil and natural gas production to be
consistent with special directives for these facilities in CAA section
112(n)(4)(A). As discussed in the preamble for the proposed amendments
(71 FR 25536), in the Oil and Natural Gas Production NESHAP (40 CFR
part 63, subpart HH) we address the provisions of CAA section
112(n)(4)(A) by limiting the emission points that are aggregated for
the major source status determination of a production field facility to
only the glycol dehydration units and storage vessels with flash
emission potential, as defined in the rule (see 40 CFR 63.761).
Consistent with our approach used for subpart HH, we are amending
subpart GGGGG to specify that for a major source status determination
of a production field facility, only the HAP emissions from the glycol
dehydration units and storage vessels with the potential for flash
emissions, as defined in subpart HH, are to be aggregated with the HAP
emissions from the site remediation activities at the facility.
Several commenters on the proposed amendments stated that in
compliance with the CAA section 112(n)(4) statutory directives, EPA
should provide a similar applicability provision in 40 CFR part 63,
subpart GGGGG for natural gas transmission and storage facilities
consistent with the major source definition in the Natural Gas
Transmission and Storage Facilities NESHAP (40 CFR part 63, subpart
HHH). We agree that such a provision is appropriate, and are amending
subpart GGGGG to specify that for natural gas transmission and storage
facilities, HAP emissions are to be aggregated according to the
definition of major source in Sec. 63.1271 for a major source
determination.
B. 1 Megagram (Mg) Site Remediation Applicability Exemption
The final amendments clarify the 40 CFR part 63, subpart GGGGG
language with respect to how the 1 Mg applicability exemption is to be
applied at a facility. Under this applicability exemption, site
remediation activities conducted at your facility are not subject to
the requirements of subpart GGGGG (except for certain recordkeeping
requirements) if you determine that the total quantity of the HAP that
is contained in the remediation material excavated, extracted, pumped,
or otherwise removed during all of the site remediations conducted at
your facility is less than 1 Mg annually. This final rule language for
the exemption provisions does not change how the 1 Mg limit is applied
nor change the documentation requirements for the exemption, but adds
clarifying language stating that the 1 Mg limit applies on a facility-
wide, annual basis and that there is no restriction to the number of
site remediations that can be conducted under the exemption. Also, in
response to public comments on the proposed regulatory language, the
term ``annual'' was substituted for ``calendar year'', and language was
added to the final rule stating that a Title V permit does not have to
be reopened or revised solely to include the recordkeeping requirement
required for the 1 Mg exemption. However, the recordkeeping requirement
must be included in the facility's Title V permit the next time the
permit is renewed, reopened, or revised for another reason.
C. Short-Term Site Remediation Exemption (30-Day)
Subpart GGGGG of 40 CFR part 63 is amended to clarify the rule
language with respect to our intent for application of the 30-day site
remediation exemption, including those situations when the remediation
material is transferred off-site. Under this exemption, site
remediations at your facility with affected sources subject to
regulation under subpart GGGGG that can be completed within 30 days are
exempted from having to meet the air emission control requirements
specified in this final rule. The final rule language explicitly
defines the beginning and end of the 30-day period for the purpose of
qualifying for the exemption.
The first day of the 30-day exemption period is defined as the day
on which you initiate any action that removes, destroys, degrades,
transforms, immobilizes, or otherwise manages the remediation
materials. Certain activities that you perform to prepare for the
actual cleanup of the contaminated media are not counted as part of the
30-day period. The period of time (i.e., number days) that you are
required to perform the following activities are not counted as part of
the 30-day interval that cannot be exceeded in order to qualify for the
exemption provided that these activities are completed before the
actual site cleanup begins: Activities to characterize the type and
extent of the contamination by collecting and analyzing samples;
activities to obtain permits from Federal, State, or local authorities
to conduct the site remediation; activities to schedule workers and
necessary equipment; and activities to arrange for contractor or third
party assistance in performing the site remediation.
The last day of the 30-day exemption period is defined as the day
on which all of the remediation materials generated by the cleanup have
been treated or disposed of in a manner such that the organic HAP in
the material no longer have a reasonable potential for volatilizing and
being released to the atmosphere (e.g., placed in a landfill). The
exemption does not apply to a site remediation where the only
activities completed during the 30-day period are excavating, pumping,
or otherwise removing the remediation material from the contaminated
area, and then storing this material on-site (e.g., in waste piles,
tanks, or containers) to be treated or disposed at some later date
after the end of the 30-day period. In this case, the processes and
equipment used for site remediation need to meet the applicable air
emission control requirement in 40 CFR part 63, subpart GGGGG (unless
the site remediation qualifies for another exemption allowed under the
rule).
It was our intent that this exemption be used for those short-term
site remediations for which all of the remediation materials generated
by the cleanup are treated or disposed within the 30-day period to meet
the requirement that the organic HAP constituents in the materials no
longer have a reasonable potential for volatilizing and subsequent
release to the atmosphere. However, we recognize that in some
situations where the remediation materials are shipped off-site for
treatment or disposal, unexpected special circumstances
[[Page 69014]]
beyond the direct control of the facility owner or operator may not
allow the final treatment or disposal of the remediation material sent
to the off-site location to be completed within the 30-day period
required to qualify for the exemption. To address these situations,
this final rule includes a provision allowing you to qualify for the
exemption provided that all of the remediation material generated by
your cleanup is transferred off-site within the 30-day exemption period
according to the existing requirements specified in section 63.7936 of
subpart GGGGG for remediation material transferred to another party or
shipped to another facility. The requirements in section 63.7936 apply
to the off-site transfer of remediation materials that have an average
total average volatile organic HAP (VOHAP) concentration equal to or
greater than 10 parts per million by weight (ppmw), and provide the
owner or operator of the affected facility from which the remediation
material is transferred with several compliance options. This final
rule adds the requirement that you must include in the applicable
shipping documentation used to transfer the remediation material off-
site, in addition to any notifications and certifications required
under section 63.7936, a statement that the shipped material was
generated by a site remediation activity subject to the conditions
specified for the 30-day exemption. The statement must include the date
on which you initiated the site remediation activity generating the
shipped remediation materials and the date 30 calendar days following
your initiation date.
D. Point of Determination of Remediation Material VOHAP Concentration
Subpart GGGGG of 40 CFR part 63 applies the air emission control
requirements for remediation material management units (i.e., tanks,
surface impoundments, containers, oil/water separators, organic/water
separators and transfer systems) to those units that manage remediation
material with an average VOHAP concentration equal to or greater than
500 ppmw. The final rule revises the applicable regulatory language in
subpart GGGGG referring to the point at which the facility owner or
operator determines the average VOHAP concentration of a remediation
material. The final rule implements our original intended VOHAP
determination procedure by reinstating the regulatory language and
terminology we originally proposed for rule, and removing the term
``point-of-extraction'' from the rule.
Under the amended 40 CFR part 63, subpart GGGGG, you are required
to determine the average total VOHAP concentration of the remediation
material at a point prior to or within a remediation material
management unit. Thus, once the VOHAP concentration for a remediation
material has been determined to be less than 500 ppmw, all remediation
material management units downstream from the point of determination
that manage this material are no longer required to meet the air
emission control requirements in subpart GGGGG unless a remediation
process is used that concentrates all, or part of, the remediation
material being managed in the unit such that the VOHAP concentration of
the material increases to 500 ppmw or more. The amended regulatory
language also clarifies that any free product returned to a
manufacturing process is no longer subject to the air emission control
requirements in subpart GGGGG.
E. Requirements for Equipment Leaks
The final rule adds a compliance option to 40 CFR part 63, subpart
GGGGG, air emission control requirements for those affected equipment
leak sources already using air pollution controls or work practices to
comply with another subpart under 40 CFR part 61 or 40 CFR part 63.
Under this option, the affected source is in compliance with subpart
GGGGG if the HAP emissions from the affected equipment leak source are
controlled in compliance with the applicable standards specified in the
other subpart in part 61 or 63 that the affected source is subject.
This final rule extends the same compliance option that subpart GGGGG
already allows for process vents and remediation material management
units to equipment leak sources.
If you choose to comply with this option, you must comply with all
of the applicable emissions limitations and work practice standards
under the other subpart (e.g., you implement leak detection and control
measures to reduce HAP emissions as specified by the applicable
subpart). This provision does not apply to any exemption of the
affected source from the emissions limitations and work practice
standards allowed by the other applicable subpart.
F. Other Rule Corrections
For purposes of implementing the requirements of subpart GGGGG,
Table 1 in the rule lists the specific organic chemical compounds,
isomers, and mixtures that are HAP. The final rule updates this table
to be consistent with EPA's current HAP list. The final rule removes
from Table 1 the listings for 1,1-dimethyl hydrazine and methyl ethyl
ketone. Both of these organic chemical compounds have been delisted as
HAP.
Provisions in 40 CFR part 63, subpart GGGGG related to startup,
shutdown, and malfunction plan requirements have been revised, as
appropriate, to be consistent with the amendments to the General
Provisions under subpart A to 40 CFR part 63 that we promulgated on
April 20, 2006 (71 FR 20446).
The final rule includes changes to the cross-reference citations in
Sec. Sec. 63.7938(b)(2), 63.7938(d)(2), 63.7938(d)(3), 63.7941(h),
63.7950(c), 63.7884(b)(2), and Table 3 of the rule to cite the correct
provision in 40 CFR part 63, subpart GGGGG that we had intended to be
referenced. Also, the final amendments correct terminology,
typographical, and grammatical errors in specific provisions of subpart
GGGGG that have been identified since the rule was originally
promulgated. The final rule replaces the rule language with the correct
cross-reference citation, term, or wording, but do not change any of
the technical or administrative requirements of the rule.
III. 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, 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.
The final rule results in no changes to the information collection
requirements of the existing rule. OMB has previously approved the
information collection requirements contained in 40 CFR part 63,
subpart GGGGG, under the provisions of the Paperwork Reduction Act, 44
U.S.C. 3501 et seq., and has assigned OMB control number 2060-0534, EPA
ICR number 2062.02. A copy of the OMB approved Information Collection
Request (ICR) may be obtained from Susan Auby; Collection Strategies
Division; U.S. EPA (2822T); 1200 Pennsylvania Ave., NW.; Washington, DC
20460 or by calling (202) 566-1672.
Burden means the total time, effort, or financial resources
expended by persons to generate, maintain, retain, or disclose or
provide information to or for a Federal agency. This includes the time
needed to review instructions; develop,
[[Page 69015]]
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 will
not have a significant economic impact on a substantial number of small
entities. Small entities include small businesses, small organizations,
and small governmental jurisdictions.
For the purposes of assessing the impacts of the final rule on
small entities, small entity is defined as: (1) A small business as
defined by the Small Business Administration at 13 CFR 121.201; (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 the final rule on small
entities, I certify that this action will not have a significant
economic impact on a substantial number of small entities. The small
entities that may be directly regulated by the rule include small
businesses and small governmental jurisdictions. We have determined
that there is little or no impact on any affected small entities
because the final rule amends existing regulations to clarify specific
provisions and to correct technical omissions and editorial errors.
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 to the private sector, of $100 million or more in any
1 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 the final rule does 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 to the
private sector in any 1 year. Thus, the final rule is not subject to
the requirements of sections 202 and 205 of the UMRA. In addition, EPA
has determined that the final rule contains no regulatory requirements
that might significantly or uniquely affect small governments, because
they contain no requirements that apply to such governments or impose
obligations upon them.
E. Executive Order 13132: Federalism
Executive Order 13132, entitled ``Federalism'' (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.''
The final rule does not have federalism implications. The final
rule does 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. The final rule does
not add any new requirements to the current rule, they only clarify our
intent and correct errors. Thus, Executive Order 13132 does not apply
to the final amendments.
F. Executive Order 13175: Consultation and Coordination With Indian
Tribal Governments
Executive Order 13175, entitled ``Consultation and Coordination
with Indian Tribal Governments'' (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.'' The final rule does not have
tribal implications, as specified in Executive Order 13175. This action
does not have substantial direct effects on tribal governments, on the
relationship between the Federal government and Indian tribes, or on
the distribution of power and responsibilities between the Federal
government and Indian tribes. Thus, Executive Order 13175 does not
apply to the final rule.
G. Executive Order 13045: Protection of Children From Environmental
Health and Safety Risks
Executive Order 13045 (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 EPA.
EPA interprets Executive Order 13045 as applying only to those
regulatory
[[Page 69016]]
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. The final rule is not subject to
the Executive Order because they are based on control technology and
not on health or safety risks.
H. Executive Order 13211: Actions That Significantly Affect Energy
Supply, Distribution, or Use
This action is not a ``significant energy action'' as defined in
Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use'' (66 FR
28355, May 22, 2001) because it is not likely to have a significant
adverse effect on the supply, distribution, or use of energy because it
only clarifies our intent and corrects errors in the existing rule.
Further, we have concluded that the final rule is not likely to have
any adverse energy effects.
I. National Technology Transfer Advancement Act
Section 12(d) of the National Technology Transfer and Advancement
Act of 1995 (NTTAA), Public Law No. 104-113, 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
one or more VCS bodies. The NTTAA directs EPA to provide Congress,
through OMB, explanations when the Agency does not use available and
applicable VCS.
This action does not involve any new technical standards or the
incorporation by reference of existing technical standards. Therefore,
the consideration of VCS is not relevant to this action.
J. 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 the Congress and to the Comptroller
General of the United States. EPA will submit a report containing the
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 are
effective on November 29, 2006.

2. Section 63.7881 is amended by revising paragraphs (a)(3) and (c) to
read as follows:
Sec. 63.7881 Am I subject to this subpart?
(a) * * *
(3) Your facility is a major source of HAP as defined in Sec.
63.2, except as specified in paragraph (a)(3)(i) or (ii) of this
section. A major source emits or has the potential to emit any single
HAP at the rate of 10 tons (9.07 megagrams) or more per year or any
combination of HAP at a rate of 25 tons (22.68 megagrams) or more per
year.
(i) For production field facilities, as defined in Sec. 63.761,
only the HAP emissions from the glycol dehydration units and storage
vessels with the potential for flash emissions (both as defined in
Sec. 63.761) shall be aggregated with the HAP emissions from the site
remediation activities at the facility for a major source
determination.
(ii) For natural gas transmission and storage facilities, HAP
emissions shall be aggregated in accordance with the definition of
major source in Sec. 63.1271 for a major source determination.
* * * * *
(c) Your site remediation activities are not subject to the
requirements of this subpart, except for the recordkeeping requirements
in this paragraph, provided that you meet the requirements specified in
paragraphs (c)(1) through (c)(3) of this section.
(1) You determine that the total quantity of the HAP listed in
Table 1 to this subpart that is contained in the remediation material
excavated, extracted, pumped, or otherwise removed during all of the
site remediations conducted at your facility is less than 1 megagram
(Mg) annually. This exemption applies the 1 Mg limit on a facility-
wide, annual basis, and there is no restriction to the number of site
remediations that can be conducted during this period.
(2) You must prepare and maintain at your facility written
documentation to support your determination that the total HAP quantity
in your remediation materials for the year is less than 1 Mg. The
documentation must include a description of your methodology and data
used for determining the total HAP content of the remediation material.
(3) Your Title V permit does not have to be reopened or revised
solely to include the recordkeeping requirement specified in paragraph
(c)(2) of this section. However, the requirement must be included in
your permit the next time the permit is renewed, reopened, or revised
for another reason.

3. Section 63.7884 is revised to read as follows:
Sec. 63.7884 What are the general standards I must meet for each site
remediation with affected sources?
(a) For each site remediation with an affected source designated
under Sec. 63.7882, you must meet the standards specified in
Sec. Sec. 63.7885 through 63.7955, as applicable to your affected
source, unless your site remediation meets the requirements for an
exemption under paragraph (b) of this section.
(b) A site remediation that is completed within 30 consecutive
calendar days according to the conditions in paragraphs (b)(1) through
(3) of this section is not subject to the standards under paragraph (a)
of this section. This exemption cannot be used for a site remediation
involving the staged or intermittent cleanup of remediation material
whereby the remediation activities at the site are started, stopped,
and then re-started in a series of intervals, with durations less than
30-days per interval, when the time period from the beginning of the
first interval to the end of the last interval exceeds 30 days.
(1) The 30 consecutive calendar day period for a site remediation
that qualifies for this exemption is determined according to actions
taken by you as defined in paragraphs (b)(1)(i) through (iii) of this
section.
(i) The first day of the 30-day period is defined as the day on
which you initiate any action that removes, destroys, degrades,
transforms, immobilizes, or otherwise manages the
[[Page 69017]]
remediation materials. The following activities, when completed before
beginning this initial action, are not counted as part of the 30-day
period: Activities to characterize the type and extent of the
contamination by collecting and analyzing samples; activities to obtain
permits from Federal, State, or local authorities to conduct the site
remediation; activities to schedule workers and necessary equipment;
and activities to arrange for contractor or third party assistance in
performing the site remediation.
(ii) The last day of the 30-day period is defined as the day on
which treatment or disposal of all of the remediation materials
generated by the cleanup is completed such that the organic
constituents in these materials no longer have a reasonable potential
for volatilizing and being released to the atmosphere.
(iii) If treatment or disposal of the remediation materials is
conducted at an off-site facility where the final treatment or disposal
of the material cannot, or may not, be completed within the 30-day
exemption period, then the shipment of all of the remediation material
generated from your cleanup that is transferred to another party, or
shipped to another facility, within the 30-day period, must be
performed according to the applicable requirements specified in Sec.
63.7936.
(2) For the purpose of complying with paragraph (b)(1) of this
section, if you ship or otherwise transfer the remediation material
off-site you must include in the applicable shipping documentation, in
addition to any notifications and certifications required under Sec.
63.7936, a statement that the shipped material was generated by a site
remediation activity subject to the conditions of this exemption. The
statement must include the date on which you initiated the site
remediation activity generating the shipped remediation materials, as
specified in paragraph (b)(1)(i) of this section, and the date 30
calendar days following your initiation date.
(3) You must prepare and maintain at your facility written
documentation describing the exempted site remediation, and listing the
initiation and completion dates for the site remediation.

(b) * * *
(2) You determine that the average total VOHAP concentration, as
defined in Sec. 63.7957, of the remediation material managed in the
remediation material management unit material is less than 500 ppmw.
You must follow the requirements in Sec. 63.7943 to demonstrate that
the VOHAP concentration of the remediation material is less than 500
ppmw. Once the VOHAP concentration for a remediation material has been
determined to be less than 500 ppmw, all remediation material
management units downstream from the point of determination managing
this material meet the requirements of this paragraph unless a
remediation process is used that concentrates all, or part of, the
remediation material being managed in the unit such that the VOHAP
concentration of the material could increase. Any free product returned
to the manufacturing process (e.g., recovered oil returned to a storage
tank at a refinery) is no longer subject to this subpart.

equipment component that is part of the affected source by implementing
leak detection and control measures according to the standards
specified in Sec. Sec. 63.7920 through 63.7922 unless you elect to
meet the requirements in paragraph (b) of this section.
(b) If the affected equipment leak source is also subject to
another subpart in 40 CFR part 61 or 40 CFR part 63, you may control
emissions of the HAP listed in Table 1 to this subpart from the
affected equipment leak source in compliance with the standards
specified in the other applicable subpart. This means you are complying
with all applicable emissions limitations and work practice standards
under the other subpart (e.g., you implement leak detection and control
measures to reduce HAP emissions as specified by the applicable
subpart). This provision does not apply to any exemption of the
affected source from the emissions limitations and work practice
standards allowed by the other applicable subpart.

(a) General requirements. You must determine the average total
VOHAP concentration of a remediation material using either direct
measurement as specified in paragraph (b) of this section or by
knowledge as specified in paragraph (c) of this section. These methods
may be used to determine the average VOHAP concentration of any
material listed in (a)(1) through (3) of this section.
(1) A single remediation material stream; or
(2) Two or more remediation material streams that are combined
prior to, or within, a remediation material management unit or
treatment process; or
(3) Remediation material that is combined with one or more non-
remediation material streams prior to, or within, a remediation
material management unit or treatment process.
(b) Direct measurement. To determine the average total VOHAP
concentration of a remediation material using direct measurement, you
must use the procedures in paragraphs (b)(1) through (3) of this
section.
(1) Sampling. Samples of each material stream must be collected
from the container, pipeline, or other device used to deliver each
material stream prior to entering the remediation material management
unit or treatment process in a manner such that volatilization of
organics contained in the sample is minimized and an adequately
representative sample is collected and maintained for analysis by the
selected method.
* * * * *
(3) Calculations. The average total VOHAP concentration (C) on a
mass-weighted basis must be calculated by using the results for all
samples analyzed according to paragraph (b)(2) of this section and
Equation 1 of this section as follows:
[GRAPHIC] [TIFF OMITTED] TR29NO06.007
Where:
C = Average VOHAP concentration of the material on a mass-weighted
basis, ppmw.
i = Individual sample ``i'' of the material.
n = Total number of samples of the material collected (at least 4
per stream) for the averaging period (not to exceed 1 year).
Qi = Mass quantity of material stream represented by
Ci, kilograms per hour (kg/hr).
QT = Total mass quantity of all material during the
averaging period, kg/hr.
Ci = Measured VOHAP concentration of sample ``i'' as
determined according to the requirements of paragraph (b)(2) of this
section, ppmw.
(c) Knowledge of the material. To determine the average total VOHAP
concentration of a remediation material using knowledge, you must use

* * * * *
Deviation means any instance in which an affected source subject to
this subpart, or an owner or operator of such a source:
(1) Fails to meet any requirement or obligation established by this
subpart, including but not limited to any emissions limitation
(including any operating limit), or work practice standard;
(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 affected source required to
obtain such a permit; or
[[Page 69020]]
(3) Fails to meet any emissions limitation, (including any
operating limit), or work practice standard in this subpart during
startup, shutdown, or malfunction, regardless of whether or not such
failure is permitted by this subpart.
* * * * *
Transfer system means a stationary system for which the predominant
function is to convey liquids or solid materials from one point to
another point within a waste management operation or recovery
operation. For the purpose of this subpart, the conveyance of material
using a container (as defined for this subpart) or a self-propelled
vehicle (e.g., a front-end loader) is not a transfer system. Examples
of a transfer system include but are not limited to a pipeline, an
individual drain system, a gravity-operated conveyor (such as a chute),
and a mechanically-powered conveyor (such as a belt or screw conveyor).
