SUPPLEMENTARY INFORMATION:

Regulated Entities. The regulated categories and entities affected by the NESHAP include:

Category	NAICS 1	Examples of regulated entities
Industry	325211 325192 325188 32411 49311 49319 48611 42269 42271	Site remediation activities at businesses at which materials containing organic HAP currently are or have been in the past stored, processed, treated, or otherwise managed at the facility. These facilities include: organic liquid storage terminals, petroleum refineries, chemical manufacturing facilities, and other manufacturing facilities with co-located site remediation activities.
Federal Government		Federal agency facilities that conduct site remediation activities to clean up materials contaminated with organic HAP.
State/ Local/ Tribal Government		Tribal governments that conduct site remediation activities to clean up materials contaminated with organic HAP.
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.

Worldwide Web (WWW). In addition to being available in the docket, an electronic copy of this final action will also be available on the Worldwide Web through the Technology Transfer Network (TTN). Following signature, a copy of this final rule will be posted on the TTN's policy and guidance page for newly proposed or promulgated rules at the following address: http://www.epa.gov/​ttn/​oarpg/​. The TTN provides information and technology exchange in various areas of air pollution control.

Judicial Review. Under section 307(b)(1) of the Clean Air Act (CAA), judicial review of the final rule is available only by filing a petition for review in the U.S. Court of Appeals for the District of 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 CAA, the requirements established by the final rule may not be challenged separately in any civil or criminal proceedings brought by EPA to enforce these requirements.

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 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 § 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 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 §§ 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 [phone].

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, 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 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.

List of Subjects in 40 CFR Part 63

• Environmental protection
• Air pollution control
• Hazardous substances
• Reporting and recordkeeping requirements

Dated: November 22, 2006.

Stephen L. Johnson,

Administrator.

For the reasons stated in the preamble, title 40, chapter I, part 63, of the Code of the Federal Regulations is amended as follows:

PART 63—[AMENDED]

1. The authority citation for part 63 continues to read as follows:

Authority: 42 U.S.C. 7401, et seq.

Subpart GGGGG—[Amended]

2. Section 63.7881 is amended by revising paragraphs (a)(3) and (c) to read as follows:

§ 63.7881

Am I subject to this subpart?

(a) * * *

(3) Your facility is a major source of HAP as defined in § 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 § 63.761, only the HAP emissions from the glycol dehydration units and storage vessels with the potential for flash emissions (both as defined in § 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 § 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.

§ 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 § 63.7882, you must meet the standards specified in §§ 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 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 § 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 § 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.

(2) You determine that the average total VOHAP concentration, as defined in § 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 § 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.

How do I determine the average VOHAP concentration of my remediation material?

(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 (C̄) 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:

Where:

C̄ = 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).

Q_i = Mass quantity of material stream represented by C_i, kilograms per hour (kg/hr).

Q_T = Total mass quantity of all material during the averaging period, kg/hr.

C_i = 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 the procedures in paragraphs (c)(1) through (3) of this section.

* * * * *

22. Section 63.7950 is amended by revising paragraph (c) to read as follows:

§ 63.7950

§ 63.7957

What definitions apply to this subpart?

* * * * *

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

(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).
