06-6419. National Emission Standards for Hazardous Air Pollutants: Organic Liquids Distribution (Non-Gasoline)

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Final rule; amendments; notice of final action on reconsideration.

SUMMARY:

EPA is promulgating amendments to the national emission standards for hazardous air pollutants for organic liquids distribution (non-gasoline) (OLD NESHAP), which EPA promulgated on February 3, 2004. After promulgation of the final OLD NESHAP, the Administrator received petitions for administrative reconsideration of the promulgated rule, and several petitions for judicial review of the final rule were filed in the United States Court of Appeals for the District of Columbia Circuit. On November 14, 2005, pursuant to a settlement agreement between some of the parties to the litigation, EPA published a notice of proposed amendments to address some of the concerns raised in the petitions and requested comments on the proposed amendments. In this action, EPA is promulgating those amendments, adding additional vapor balancing options, and making technical corrections to the final rule.

DATES:

The final rule amendments are effective on July 28, 2006. The incorporation by reference of certain publications listed in the final rule is approved by the Director of the Federal Register as of July 28, 2006.

I. What Is the Statutory Authority for the Final Rule?

Section 112 of the CAA requires EPA to list categories and subcategories of major sources and area sources of hazardous air pollutants (HAP) and to establish NESHAP for the listed source categories and subcategories. OLD was listed on July 16, 1992 (57 FR 31576). Major sources of HAP are those that have the potential to emit at least 10 tons per year (tpy) of any one HAP or 25 tpy of any combination of HAP.

II. Background

On February 3, 2004 (69 FR 5063), EPA promulgated the OLD NESHAP (40 CFR part 63, subpart EEEE) pursuant to section 112 of the CAA. In response to several petitions for administrative reconsideration of the OLD NESHAP and several petitions for judicial review filed with the United States Court of Appeals for the District of Columbia Circuit and pursuant to a settlement agreement between some of the parties to the litigation, EPA proposed amendments (November 14, 2005, 70 FR 69210) to subpart EEEE. EPA received comments from four entities. The final notice presents EPA's responses to those comments and promulgates amendments to subpart EEEE in response to the petitions and public comments.

As noted in the November 14, 2005, Federal Register notice, EPA will be taking separate action to address an administrative petition for reconsideration and a petition for judicial review concerning wastewater sources that were not addressed in the settlement agreement that gave rise to the November 14, 2005, proposal.

III. What Revisions Were Made as a Result of Comments Received on the Proposed Amendments?

Based on consideration of the comments received on the proposed amendments, EPA is revising the OLD rule provisions addressing vapor balancing for transfer racks by providing an additional, equivalent control option that allows routing of displaced HAP vapors to a storage tank with a common header. In addition, EPA is adding an option to allow vapor balancing back to the transport vehicle for storage tanks when they are being filled with organic liquids. EPA is withdrawing the proposed amendment that would have allowed vapor balancing transfer rack emissions to a process unit because this option is already available through other language. EPA is making additional changes, which are either technical corrections or clarifications.

IV. What Are the Responses to Significant Comments?

EPA received four public comment letters on the proposed amendments. Most of the comments from three of the commenters were supportive of the proposed amendments, and EPA thanks the commenters for that support. The following summarizes the comments that sought changes to the proposed amendments and EPA's response to those comments.

A. Compliance Date Extension for All Storage Tanks

Comment: One commenter noted that 40 CFR 63.2342(b)(2) allows owners and operators of storage tanks with floating roofs up to 10 years or after the next degassing and cleaning activities to comply with the regulations for such storage tanks. The commenter requested that this compliance provision be extended to all storage tanks, because, in their opinion, the emissions produced by emptying and degassing a tank in order to perform the required alterations would exceed the cumulative reduction in emissions occurring in the years following alteration of the tank.

Response: EPA notes that this comment does not pertain to the proposed amendments to subpart EEEE in the November 14, 2005, Federal Register notice. Nevertheless, EPA is responding to this request because it is important to clarify this issue. This provision (40 CFR 63.2342(b)(2)) is only applicable to storage tanks with floating roofs and is not applicable to other types of storage tanks (i.e., fixed roof storage tanks). The compliance date provisions for floating roof tanks are consistent with similar rules such as the Hazardous Organic NESHAP (HON). The rationale for allowing extended compliance time for floating roof tanks (up to 10 years) that must upgrade fittings to comply with this rule was that the incremental reductions associated with upgrading controls generally would not exceed the emissions generated as a result of emptying and degassing. However, this is not the case for fixed roof tanks that are essentially uncontrolled. Further, the commenter did not provide substantive information regarding emission potentials and offsetting cleaning and degassing emission potentials for fixed roof tanks. Thus, the technical basis for the compliance date provision is only applicable to storage tanks with floating roofs and not to storage tanks with fixed roofs. Therefore, EPA is not changing this provision as requested by the commenter.

B. Vapor Balancing

Comment: Two commenters requested that 40 CFR 63.2346(b)(3)(i) and (ii) be revised to allow organic HAP vapors displaced during loading to be vented to another storage tank connected by common header in addition to the tank from which the organic HAP vapor originated or to a process unit, as currently allowed. The commenters stated that this would afford the same flexibility afforded in the HON and the Miscellaneous Organic NESHAP.

Response: EPA agrees that the alternative proposed by the commenters is both appropriate and applicable to the OLD source category. The option provides owners and operators flexibility in meeting the requirements of 40 CFR part 63, subpart EEEE, without sacrificing the level of emission reductions being achieved. Further, making this change would provide consistency between similar emission sources being controlled under similar rules. Therefore, EPA has revised the rule to incorporate this option for vapor balancing for transfer racks.

In addition, other rules (e.g., see 40 CFR 63.119(g) of the HON) allow an owner or operator to route emissions from the filing of storage tanks back to the transport vehicle from which the organic liquid originates. EPA has determined that, like vapor balancing through a common header, the inclusion of this vapor balancing option for storage tanks when they are being filled provides both consistency between the OLD rule and other similar subparts and flexibility to owners and operators without sacrificing emission reduction. Further, because some of the transport vehicles to which vapors are returned are refilled offsite, EPA has included requirements for such offsite facilities. Therefore, EPA has added this provision, along with the necessary requirements for initial and continuous compliance and for keeping records.

Finally, EPA is withdrawing the proposed amendment that would have allowed vapor balancing transfer rack emissions back to a process unit. In the final rule, transfer racks may be routed back to a process (see 40 CFR 63.2346(b)(2)). As part of the proposed amendments (see 40 CFR 63.2346(b)(3)(i) and 40 CFR 63.2346(b)(3)(ii)), vapor balancing these emissions back to a process unit was proposed. Upon further consideration, both options essentially describe one single practice, and therefore, EPA recognizes that it is not necessary for the final rule to contain both options; that 40 CFR 63.2346(b)(2) of the final rule is sufficient. Therefore, EPA is withdrawing the proposed vapor balancing of transfer racks back to a process unit. No changes have been made concerning the use of vapor balancing transfer rack emissions back to the storage tank from which the liquid originated.

We also would like to address the provisions of 40 CFR 63.2378(d), which allow emissions bypasses of fuel gas systems or the process for up to 240 hours per year. These provisions allow bypassing that is necessary for valid safety or operational reasons but are only applicable if emissions are routinely physically vented to fuel gas systems or the process. This means that the owner or operator can not use the language of 40 CFR 63.2378(d) to exempt a transfer rack that is used for less than 240 hours per year from control requirements.

C. Recordkeeping and Reporting for Emissions Sources That Do Not Require Control

Comment: One commenter requested that the recordkeeping requirements proposed in 40 CFR 63.2343(a) for tanks under 5,000 gallons capacity and for transfer racks that only unload organic liquids be eliminated in their entirety. The commenter stated that such recordkeeping and reporting requirements for these sources impose unnecessary administrative requirements on facilities. The commenter fails to see the benefit in keeping records for tanks that physically cannot change in size or for unloading racks that only unload certain materials.

Response: Addressing storage tanks first, EPA points out that owners and operators of facilities subject to 40 CFR part 63, subpart EEEE will have to make a determination as to which storage tanks are storing organic liquids subject to subpart EEEE and which are not. If a storage tank is storing an organic liquid subject to subpart EEEE, the tank is subject to subpart EEEE. For storage tanks subject to subpart EEEE, the owner or operator would then identify the capacity of each tank in order to identify those that are less than 5,000 gallons in capacity and which do not require control. Proposed 40 CFR 63.2343(a) only applies to those tanks that are storing an organic liquid subject to subpart EEEE and with capacities of less than 5,000 gallons. This applicability is stated clearly in proposed 40 CFR 63.2343(a) (emphasis added):

(a) For each storage tank subject to this subpart having a capacity of less than 18.9 cubic meters (5,000 gallons) and for each transfer rack subject to this subpart that only unloads organic liquids (i.e., no organic liquids are loaded at any of the transfer racks), you must keep documentation that verifies that each storage tank and transfer rack identified in paragraph (a) of this section is not required to be controlled.

Proposed 40 CFR 63.2343(a) requires only that the owner or operator keep a record of the size determination; that is, by virtue of having a capacity of less than 5,000 gallons, the storage tank is not required to be controlled. The proposed paragraph does not apply to: (1) Storage tanks storing a liquid that is not an organic liquid and (2) storage tanks storing an organic liquid that is not subject to 40 CFR part 63, subpart EEEE.

As correctly pointed out by the commenter, storage tanks do not change in size. Therefore, there would be no further effort required on the part of the owner or operator to document that the storage tank is not subject to control; that is, the original determination is sufficient.

Proposed 40 CFR 63.2343(a) also required that the documentation by kept up-to-date:

The documentation must be kept up-to-date (i.e., all such emission sources at a facility are identified in the documentation regardless of when the documentation was last compiled) and must be in a form suitable and readily available for expeditious inspection and review according to § 63.10(b)(1), including records stored in electronic form in a separate location.

EPA points out that in explaining what is meant by “up-to-date,” the phrase “all such emission sources at a facility” is used. Within the context of the entire paragraph, this phrase unambiguously refers back to those storage tanks for which the documentation under 40 CFR 63.2343(a)(1) is being requested; that is, storage tanks subject to 40 CFR part 63, subpart EEEE, which are storage tanks storing organic liquids subject to subpart EEEE. EPA does not believe it necessary to revise the regulatory text to further clarify the phrase “all such emission sources at a facility.” This phrase does not apply to either storage tanks storing liquids that are not organic liquids or to storage tanks storing organic liquids that are not subject to subpart EEEE. To better identify the type of documentation that is acceptable, EPA has revised 40 CFR 63.2343(a) to allow the use of piping and instrumentation diagrams (P&ID) to identify tanks (and transfer racks) subject to 40 CFR 63.2343(a).

EPA reemphasizes that proposed 40 CFR 63.2343(a) only applies to storage tanks storing an organic liquid subject to 40 CFR part 63, subpart EEEE. If a facility has storage tanks of less than 5,000 gallon capacity, but those storage tanks do not store organic liquids (as defined in subpart EEEE), then there are no recordkeeping requirements for those tanks under 40 CFR 63.2343(a)(1) or under any other part of subpart EEEE. Furthermore, there are no recordkeeping requirements under subpart EEEE for storage tanks of any size that either do not store and organic liquid or for storage tanks storing organic liquids that are not subject to subpart EEEE.

EPA further points out that 40 CFR 63.10(b)(3) of subpart A (the General Provisions) does not impose any recordkeeping requirements under the OLD maximum achievable control technology (MACT) for storage tanks that are not storing organic liquids and, therefore, not part of the OLD source category. The determination of applicability of 40 CFR 63.10(b)(3) applies to stationary sources that are part of the source category, but that are not subject to the relevant standard, in this case 40 CFR part 63, subpart EEEE, based on either the source's potential to emit or a specific exclusion in the subpart. In the case of the commenter, their OLD operation is located at a major source of HAP and there are no exclusions in subpart EEEE applicable to it; therefore, their OLD operation is an affected source subject to subpart EEEE. Once this determination is made, there is no applicability of 40 CFR 63.10(b)(3) to the OLD affected source.

For other storage tanks located at their plant site that do not store organic liquids and, therefore, are not part of the OLD affected source, 40 CFR 63.10(b)(3) imposes no recordkeeping requirements, for the purposes of the OLD rule, on those storage tanks or the source to which they belong.

EPA clarified this in the preamble to the March 23, 2001, proposed amendments to the General Provisions at 66 FR 16330. We state

The current General Provisions include a requirement at 63.10(b)(3) for a source both to determine applicability and to keep a record of their determination if the source determines that it is not an affected source for a relevant standard. [A]n unintended interpretation of the General Provisions could be to require owners and operators of any source, including facilities not in the source category being regulated, to perform applicability determinations each time any NESHAP are promulgated. It was not our intent that the General Provisions require owners and operators to make a determination that they are not subject to every NESHAP that is issued.

For transfer racks, a situation similar to storage tanks exists. Only transfer racks loading or unloading organic liquids that are subject to 40 CFR part 63, subpart EEEE are affected; loading racks that load or unload only non-organic liquids (or organic liquids not subject to subpart EEEE) are not affected. For those racks that only unload organic liquids subject to subpart EEEE, owners and operators must make the initial determination that the rack only unloads such organic liquids, and then must keep a record of that determination. As long as such racks do not begin to load organic liquids subject to subpart EEEE, no further effort, beyond keeping the record readily available and up-to-date, is required on the part of the owner or operator to document that the transfer rack only unloads organic liquids subject to subpart EEEE.

Finally, EPA believes that maintaining these basic determinations in the form of a record, both for storage tanks with capacities of less than 5,000 gallons and for transfer racks that only unload organic liquids, will facilitate the time and effort an inspector would expend during an inspection of a facility and the time and effort the source would expend recreating these determinations each time they were asked.

For these reasons, EPA has not revised the proposed rule language associated with these storage tanks and transfer racks, except for the allowance of P&ID to identify such storage tanks and transfer racks.

Comment: One commenter requested that the recordkeeping and reporting requirements proposed in 40 CFR 63.2343 for storage tanks with capacities equal to or greater than 5,000 gallons that do not require control be eliminated. The commenter stated that such requirements impose an administrative burden with no environmental benefit. The commenter suggested that the more appropriate way to address these tanks is to require the owner or operator of such tanks to notify the State permitting authority at the point in time when such tanks trigger control requirements under Table 2 of 40 CFR part 63, subpart EEEE. The commenter recommended that EPA apply the same approach used in the Engine Testing MACT (40 CFR 63.9290). In the Engine Testing MACT, a source that is exclusively used for testing internal combustion engines of less than 25 horsepower is required only to submit an initial notification, meeting the requirements in the General Provisions. The initial notification for these sources also must state that the source has no additional requirements, including a brief explanation of the basis of the exclusion. No other reporting, recordkeeping, or notification requirements, including submission of startup, shutdown, and malfunction plans and compliance demonstrations, apply to sources that do not have to comply with emission limitations. According to the commenter, EPA should apply this same approach to sources that are not subject to controls under subpart EEEE.

Response: As noted in the previous response, the requirements in proposed 40 CFR 63.2343(b) only apply to storage tanks storing organic liquids subject to 40 CFR part 63, subpart EEEE. Further, an owner or operator would have to make an initial determination as to whether these larger storage tanks contain organic liquids with vapor pressures that trigger the control requirements. As long as the liquid in the tank did not change, no further action is required on the part of the owner or operator, beyond keeping the record readily available and up-to-date. If the owner or operator changes the liquids stored in such tanks, however, the owner or operator is required to make a determination as to whether or not the vapor pressure of the new liquid being stored is sufficient to require control and maintain a record of that determination, even if control is still not required.

EPA continues to believe that keeping a record of such information is important to allow an inspector to determine compliance with the OLD rule. Therefore, EPA has not revised this requirement in the final rule.

D. Technical Corrections and Clarifying Changes

EPA is making the following technical corrections and clarifications to the final rule:

1. The cross-reference to 40 CFR 63.2382(b) found in 40 CFR 63.2370(c) is incorrect. The correct cross-reference is 40 CFR 63.2382(d).

2. Item 1.b in Table 5 to 40 CFR part 63, subpart EEEE references the emission limit of “at least 95 weight percent.” This limit is applicable to storage tanks only. The applicable limit for transfer racks (both low throughput and high throughput racks) is “at least 98 weight percent.” EPA has revised the final rule to reflect accordingly.

3. In table 12 to 40 CFR part 63, subpart EEEE, 40 CFR 63.6(h)(1) through (7) are indicated as being not applicable to subpart EEEE, while 40 CFR 63.6(h)(8) and CFR 63.6(h)(9) are indicated as being applicable. 40 CFR 63.6(h) applies to opacity and visible emission standards. Upon closer examination of this apparent inconsistency, EPA has determined that all of 40 CFR 63.6(h) is not applicable, except to the extent that Method 22 observations are required as part of a flare compliance assessment. Therefore, EPA has revised the applicability of 40 CFR 63.6(h) to read as follows:

“No; except only as it applies to flares for which Method 22 observations are required as part of a flare compliance assessment.”

4. We are deleting methyl ethyl ketone (MEK) from Table 1 because MEK has been delisted by the Agency as a HAP.

5. We are correcting the cross-reference in 40 CFR 63.2346(a) for storage tanks meeting the tank capacity and liquid vapor pressure criteria for control in Table 2, item 6. The final rule referenced compliance with paragraph (a)(1) when it should have referenced compliance with either paragraphs (a)(1) or (a)(2).

6. We are revising the phrasing in 40 CFR 63.2354(a)(3) to clarify that performance evaluations for continuous monitoring systems (CMS) are only currently required for continuous emission monitoring systems. The requirements of 40 CFR 63.8 only apply if there are promulgated performance specifications for CMS, including continuous parameter monitoring systems. Currently, there are no performance specifications for the continuous parameter monitoring systems that are identified in 40 CFR part 63, subpart SS, which this subpart references. However, performance specifications for parameter monitoring systems are expected to be proposed in the future. When developing these performance specifications, the Agency will consider their application to OLD and other similar rules. For consistency, we have also clarified the applicability of CMS provisions contained in the General Provisions, 40 CFR 63.8(c)(6)-(8), (d), and (f).

7. We have added a new paragraph, 40 CFR 63.2396(e)(2), to clarify the relationship between the recordkeeping and reporting requirements of this subpart and the recordkeeping and reporting requirements for equipment leak components associated with unloading racks under other subparts. The new paragraph clarifies that such equipment leak components must be in compliance with this subpart EEEE. However, if the recordkeeping and reporting requirements of the other 40 CFR part 63 subpart are equivalent to those required by this subpart EEEE, the owner or operator may elect to continue to comply with the recordkeeping and reporting requirements under which they are currently being controlled and be considered in compliance with this subpart EEEE. This new paragraph parallels the similar relationship in the final rule provided for monitoring, recordkeeping, and reporting for control devices.

8. We have revised the definition of “annual average true vapor pressure” to clarify that the vapor pressure is to be based on organic HAP that are listed in Table 1 to this subpart EEEE.

9. We have corrected an incorrect cross-reference in the second column of Item 8 in Table 3 of this subpart EEEE. The incorrect cross-reference, 40 CFR 63.2366(c), does not exist. The correct cross-reference is 40 CFR 63.2366(b).

10. We corrected the last column of item 1.b in Table 5 and the third column of items 1 and 2 of Table 6 of this subpart EEEE by adding the phrase “for nonflare combustion devices” to the option of 20 parts per million by volume exhaust concentration. This phrase was inadvertently omitted and makes these items consistent with item 1.a.i.(5)(A)(ii) in Table 5 of this subpart EEEE.

11. We are making the description in item 2 in Table 11 of this subpart EEEE consistent with the General Provisions’ language that requires an immediate notification when an exceedance of an applicable emission standard occurs during a startup, shutdown, or malfunction episode. The language in the rule as promulgated did not reference the exceedance of an applicable emission standard for determining when an immediate notification was required.

12. We are correcting in Table 12 of this subpart EEEE how 40 CFR 63.9(j) applies to this subpart EEEE. The types of changes that 40 CFR 63.9(j) requires to be reported are covered in subpart EEEE in 40 CFR 63.2386(c) and (d). In these paragraphs, these changes would be submitted with the next compliance report. Thus, the requirement to submit these changes within 15 days after the change is not applicable to this subpart EEEE. The change in Table 12 reflects this.

13. We are revising § 63.2350(c) to be consistent with 40 CFR 63.6(e)(3), which requires the development of a startup, shutdown, and malfunction plan. The revised language, therefore, drops the phrase “and implement.” An owner or operator is still required, under 40 CFR 63.6(e)(1), to minimize emissions during a period of startup, shutdown, or malfunction; thus there is no change in the stringency of the final rule.

V. Statutory and Executive Order Reviews

A. Executive Order 12866: Regulatory Planning and Review

Under Executive Order 12866 (58 FR 51735, October 4, 1993), EPA must determine whether the regulatory action is “significant” and, therefore, subject to Office of Management and Budget (OMB) review and the requirements of the Executive Order. The Executive Order defines “significant regulatory action” as one that is likely to result in a rule that may:

(1) Have an annual effect on the economy of $100 million or more or adversely affect in a material way the economy, a sector of the economy, productivity, competition, jobs, the environment, public health or safety, or State, local, or tribal governments or communities;

(2) Create a serious inconsistency or otherwise interfere with an action taken or planned by another agency;

(3) Materially alter the budgetary impact of entitlement, grants, user fees, or loan programs or the rights and obligations of recipients thereof; or

(4) Raise novel legal or policy issues arising out of legal mandates, the President's priorities, or the principles set forth in the Executive Order.

Pursuant to the terms of Executive Order 12866, OMB has notified EPA that it considers this a “significant regulatory action” within the meaning of the Executive Order. EPA has submitted this action to OMB for review. Changes made in response to OMB suggestions or recommendations will be documented in the public record.

B. Paperwork Reduction Act

This action does not impose any new information collection burden. The final rule required owners and operators to list sources not subject to control in the first and subsequent compliance reports and to keep appropriate documentation. The final rule applied these requirements across-the-board for all emission sources not requiring control and, in general, was not specific as to what recordkeeping is required. Under the final rule amendments, we clarify how these provisions would apply to those emission sources for which control would never be required and to those emission sources for which control could be required, but is not currently required. In addition, we identify the specific circumstances under which listing in subsequent compliance reports would be required for sources for which control is not required rather than requiring all previously identified sources to be re-listed. Further, we narrow the applicability of certain sections of the General Provisions for sources for which control is not required because the proposed amendments make such application of those sections in the General Provisions unnecessary. Thus, in sum, the final rule amendments are not adding new information collection burden. However, OMB has previously approved the information collection requirements contained in the existing regulations at 40 CFR part 63, subpart EEEE under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501, et seq., and has assigned OMB control number 2060-0539, EPA Information Collection Request (ICR) number 1963.02. 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 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 are listed in 40 CFR part 9.

C. Regulatory Flexibility Act

EPA has determined that it is not necessary to prepare a regulatory flexibility analysis in connection with the final rule amendments.

For purposes of assessing the impacts of the final rule amendments on small entities, small entity is defined as: (1) A small business as defined by the Small Business Administration's regulations 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 amendments on small entities, EPA has concluded 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 proposed rule on small entities.” 5 U.S.C. 603 and 604. Thus, an agency may conclude 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.

The final rule amendments will not impose any new requirements on small entities, and will reduce some of the burden established under the promulgated rule. The final rule amendments will relieve regulatory burden by, for example, exempting all emission sources in the affected source not requiring control under the OLD NESHAP from notification, recordkeeping, and reporting requirements, except as otherwise specified for all affected small entities; excluding from the affected source storage tanks, transfer racks, transport vehicles, containers, and equipment leak components when used in special operations and to conduct maintenance activities; and allowing owners or operators of existing sources to request a compliance extension of up to 1 year if the additional time is necessary for the installation of controls. We have therefore concluded that today's final rule 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 to 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 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 1 year. Thus, the final rule amendments are not subject to the requirements of section 202 and 205 of the UMRA. In addition, the final rule amendments contain 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. Therefore, the final rule amendments are not subject to the requirements of section 203 of the UMRA.

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” is 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 amendments do not have federalism implications. They will not have new 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. They correct typographical errors, clarify provisions, or eliminate unnecessary recordkeeping and reporting requirements for emission sources for which there are no control requirements. These changes do not modify existing or create new responsibilities among EPA Regional Offices, States, or local enforcement agencies. Thus, Executive Order 13132 does not apply to the final rule amendments.

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

Executive Order 13175 (65 FR 67249, November 9, 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 amendments do not have tribal implications as specified in Executive Order 13175. They will 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, as specified in Executive Order 13175. Thus, Executive Order 13175 does not apply to the final rule amendments.

G. Executive Order 13045: Protection of Children From Environmental Health Risks 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, the Agency 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. The final rule amendments are not subject to Executive Order 13045 because it is based on technology performance and not on health or safety risks.

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

The final rule amendments are 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 they are not likely to have a significant adverse effect on the supply, distribution, or use of energy. Further, we have concluded that this rule is not likely to have any adverse energy effects.

I. National Technology Transfer and Advancement Act

As noted in the proposed rule, Section 12(d) of the National Technology Transfer and Advancement Act (NTTAA) of 1995, Public Law 104-113, 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. 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 decides not to use available and applicable VCS.

The final rule amendments involve a technical standard. EPA has decided to use ASTM D6420-99 (reapproved 2004), Standard Test Method for Determination of Gaseous Organic Compounds by Direct Interface Gas Chromatography-Mass Spectrometry, as an alternative to Method 18. This method allows the use of ASTM D6420-99 (Reapproved 2004) as an alternative to Method 18 to determine compliance with the organic HAP or total organic compounds emission limit under certain circumstances.

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 rule amendments and other required information to the United States Senate, the United States House of Representatives, and the Comptroller General of the United States prior to publication of the final rule 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). The final rule will be effective on July 28, 2006.

§ 63.2342

When do I have to comply with this subpart?

(a) If you have a new or reconstructed affected source, you must comply with this subpart according to the schedule identified in paragraph (a)(1), (a)(2), or (a)(3) of this section, as applicable.

* * * * *

(3) If, after startup of a new affected source, the total actual annual facility-level organic liquid loading volume at that source exceeds the criteria for control in Table 2 to this subpart, items 9 and 10, the owner or operator must comply with the transfer rack requirements specified in § 63.2346(b) immediately; that is, be in compliance the first day of the period following the end of the 3-year period triggering the control criteria.

(b)(1) If you have an existing affected source, you must comply with the emission limitations, operating limits, and work practice standards for existing affected sources no later than February 5, 2007, except as provided in paragraphs (b)(2) and (3) of this section.

* * * * *

(3)(i) If an addition or change other than reconstruction as defined in § 63.2 is made to an existing affected facility that causes the total actual annual facility-level organic liquid loading volume to exceed the criteria for control in Table 2 to this subpart, items 7 and 8, the owner or operator must comply with the transfer rack requirements specified in § 63.2346(b) immediately; that is, be in compliance the first day of the period following the end of the 3-year period triggering the control criteria.

(ii) If the owner or operator believes that compliance with the transfer rack emission limits cannot be achieved immediately, as specified in paragraph (b)(3)(i) of this section, the owner or operator may submit a request for a compliance extension, as specified in paragraphs (b)(3)(ii)(A) through (I) of this section. Subject to paragraph (b)(3)(ii)(B) of this section, until an extension of compliance has been granted by the Administrator (or a State with an approved permit program) under this paragraph (b)(3)(ii), the owner or operator of the transfer rack subject to the requirements of this section shall comply with all applicable requirements of this subpart. Advice on requesting an extension of compliance may be obtained from the Administrator (or the State with an approved permit program).

(A) Submittal. The owner or operator shall submit a request for a compliance extension to the Administrator (or a State, when the State has an approved 40 CFR part 70 permit program and the source is required to obtain a 40 CFR part 70 permit under that program, or a State, when the State has been delegated the authority to implement and enforce the emission standard for that source) seeking an extension allowing the source up to 1 additional year to comply with the transfer rack standard, if such additional period is necessary for the installation of controls. The owner or operator of the affected source who has requested an extension of compliance under this paragraph (b)(3)(ii)(A) and who is otherwise required to obtain a title V permit shall apply for such permit, or apply to have the source's title V permit revised to incorporate the conditions of the extension of compliance. The conditions of an extension of compliance granted under this paragraph (b)(3)(ii)(A) will be incorporated into the affected source's title V permit according to the provisions of 40 CFR part 70 or Federal title V regulations in this chapter (42 U.S.C. 7661), whichever are applicable.

(B) When to submit. (1) Any request submitted under paragraph (b)(3)(ii)(A) of this section must be submitted in writing to the appropriate authority no later than 120 days prior to the affected source's compliance date (as specified in paragraph (b)(3)(i) of this section), except as provided for in paragraph (b)(3)(ii)(B)(2) of this section. Nonfrivolous requests submitted under this paragraph (b)(3)(ii)(B)(1) will stay the applicability of the rule as to the emission points in question until such time as the request is granted or denied. A denial will be effective as of the date of denial.

(2) An owner or operator may submit a compliance extension request after the date specified in paragraph (b)(3)(ii)(B)(1) of this section provided the need for the compliance extension arose after that date, and before the otherwise applicable compliance date and the need arose due to circumstances beyond reasonable control of the owner or operator. This request must include, in addition to the information required in paragraph (b)(3)(ii)(C) of this section, a statement of the reasons additional time is needed and the date when the owner or operator first learned of the problems. Nonfrivolous requests submitted under this paragraph (b)(3)(ii)(B)(2) will stay the applicability of the rule as to the emission points in question until such time as the request is granted or denied. A denial will be effective as of the original compliance date.

(C) Information required. The request for a compliance extension under paragraph (b)(3)(ii)(A) of this section shall include the following information:

(1) The name and address of the owner or operator and the address of the existing source if it differs from the address of the owner or operator;

(2) The name, address, and telephone number of a contact person for further information;

(3) An identification of the organic liquid distribution operation and of the specific equipment for which additional compliance time is required;

(4) A description of the controls to be installed to comply with the standard;

(5) Justification for the length of time being requested; and

(6) A compliance schedule, including the date by which each step toward compliance will be reached. At a minimum, the list of dates shall include:

(i) The date by which on-site construction, installation of emission control equipment, or a process change is planned to be initiated;

(ii) The date by which on-site construction, installation of emission control equipment, or a process change is to be completed; and

(iii) The date by which final compliance is to be achieved.

(D) Approval of request for extension of compliance. Based on the information provided in any request made under paragraph (b)(3)(ii)(C) of this section, or other information, the Administrator (or the State with an approved permit program) may grant an extension of compliance with the transfer rack emission standard, as specified in paragraph (b)(3)(ii) of this section. The extension will be in writing and will—

(1) Identify each affected source covered by the extension;

(2) Specify the termination date of the extension;

(3) Specify the dates by which steps toward compliance are to be taken, if appropriate;

(4) Specify other applicable requirements to which the compliance extension applies (e.g., performance tests);

(5) Specify the contents of the progress reports to be submitted and the dates by which such reports are to be submitted, if required pursuant to paragraph (b)(3)(ii)(E) of this section.

(6) Under paragraph (b)(3)(ii) of this section, specify any additional conditions that the Administrator (or the State) deems necessary to assure installation of the necessary controls and protection of the health of persons during the extension period.

(E) Progress reports. The owner or operator of an existing source that has been granted an extension of compliance under paragraph (b)(3)(ii)(D) of this section may be required to submit to the Administrator (or the State with an approved permit program) progress reports indicating whether the steps toward compliance outlined in the compliance schedule have been reached.

(F) Notification of approval or intention to deny.

(1) The Administrator (or the State with an approved permit program) will notify the owner or operator in writing of approval or intention to deny approval of a request for an extension of compliance within 30 calendar days after receipt of sufficient information to evaluate a request submitted under paragraph (b)(3)(ii) of this section. The Administrator (or the State) will notify the owner or operator in writing of the status of his/her application; that is, whether the application contains sufficient information to make a determination, within 30 calendar days after receipt of the original application and within 30 calendar days after receipt of any supplementary information that is submitted. The 30-day approval or denial period will begin after the owner or operator has been notified in writing that his/her application is complete. Failure by the Administrator to act within 30 calendar days to approve or disapprove a request submitted under paragraph (b)(3)(ii) of this section does not constitute automatic approval of the request.

(2) When notifying the owner or operator that his/her application is not complete, the Administrator will specify the information needed to complete the application and provide notice of opportunity for the applicant to present, in writing, within 30 calendar days after he/she is notified of the incomplete application, additional information or arguments to the Administrator to enable further action on the application.

(3) Before denying any request for an extension of compliance, the Administrator (or the State with an approved permit program) will notify the owner or operator in writing of the Administrator's (or the State's) intention to issue the denial, together with:

(i) Notice of the information and findings on which the intended denial is based; and

(ii) Notice of opportunity for the owner or operator to present in writing, within 15 calendar days after he/she is notified of the intended denial, additional information or arguments to the Administrator (or the State) before further action on the request.

(4) The Administrator's final determination to deny any request for an extension will be in writing and will set forth the specific grounds on which the denial is based. The final determination will be made within 30 calendar days after presentation of additional information or argument (if the application is complete), or within 30 calendar days after the final date specified for the presentation if no presentation is made.

(G) Termination of extension of compliance. The Administrator (or the State with an approved permit program) may terminate an extension of compliance at an earlier date than specified if any specification under paragraph (b)(3)(ii)(D)(3) or paragraph (b)(3)(ii)(D)(4) of this section is not met. Upon a determination to terminate, the Administrator will notify, in writing, the owner or operator of the Administrator's determination to terminate, together with:

(1) Notice of the reason for termination; and

(2) Notice of opportunity for the owner or operator to present in writing, within 15 calendar days after he/she is notified of the determination to terminate, additional information or arguments to the Administrator before further action on the termination.

(3) A final determination to terminate an extension of compliance will be in writing and will set forth the specific grounds on which the termination is based. The final determination will be made within 30 calendar days after presentation of additional information or arguments, or within 30 calendar days after the final date specified for the presentation if no presentation is made.

(H) The granting of an extension under this section shall not abrogate the Administrator's authority under section 114 of the CAA.

(I) Limitation on use of compliance extension. The owner or operator may request an extension of compliance under the provisions specified in paragraph (b)(3)(ii) of this section only once for each facility.

* * * * *

(d) You must meet the notification requirements in §§ 63.2343 and 63.2382(a), as applicable, according to the schedules in § 63.2382(a) and (b)(1) through (3) and in subpart A of this part. Some of these notifications must be submitted before the compliance dates for the emission limitations, operating limits, and work practice standards in this subpart.

5. Section 63.2343 is added to subpart EEEE to read as follows:

§ 63.2343

What are my requirements for emission sources not requiring control?

This section establishes the notification, recordkeeping, and reporting requirements for emission sources identified in § 63.2338 that do not require control under this subpart (i.e., under paragraphs (a) through (e) of § 63.2346). Such emission sources are not subject to any other notification, recordkeeping, or reporting sections in this subpart, including § 63.2350(c), except as indicated in paragraphs (a) through (d) of this section.

(a) For each storage tank subject to this subpart having a capacity of less than 18.9 cubic meters (5,000 gallons) and for each transfer rack subject to this subpart that only unloads organic liquids (i.e., no organic liquids are loaded at any of the transfer racks), you must keep documentation that verifies that each storage tank and transfer rack identified in paragraph (a) of this section is not required to be controlled. The documentation must be kept up-to-date (i.e., all such emission sources at a facility are identified in the documentation regardless of when the documentation was last compiled) and must be in a form suitable and readily available for expeditious inspection and review according to § 63.10(b)(1), including records stored in electronic form in a separate location. The documentation may consist of identification of the tanks and transfer racks identified in paragraph (a) of this section on a plant site plan or process and instrumentation diagram (P&ID).

(b) For each storage tank subject to this subpart having a capacity of 18.9 cubic meters (5,000 gallons) or more that is not subject to control based on the criteria specified in Table 2 to this subpart, items 1 through 6, you must comply with the requirements specified in paragraphs (b)(1) through (3) of this section.

(1)(i) You must submit the information in § 63.2386(c)(1), (2), (3), and (10)(i) in either the Notification of Compliance Status, according to the schedule specified in Table 12 to this subpart, or in your first Compliance report, according to the schedule specified in § 63.2386(b), whichever occurs first.

(ii)(A) If you submit your first Compliance report before your Notification of Compliance Status, the Notification of Compliance Status must contain the information specified in § 63.2386(d)(3) and (4) if any of the changes identified in paragraph (d) of this section have occurred since the filing of the first Compliance report. If none of the changes identified in paragraph (d) of this section have occurred since the filing of the first Compliance report, you do not need to report the information specified in § 63.2386(c)(10)(i) when you submit your Notification of Compliance Status.

(B) If you submit your Notification of Compliance Status before your first Compliance report, your first Compliance report must contain the information specified in § 63.2386(d)(3) and (4) if any of the changes specified in paragraph (d) of this section have occurred since the filing of the Notification of Compliance Status.

(iii) If you are already submitting a Notification of Compliance Status or a first Compliance report under § 63.2386(c), you do not need to submit a separate Notification of Compliance Status or first Compliance report for each storage tank that meets the conditions identified in paragraph (b) of this section (i.e., a single Notification of Compliance Status or first Compliance report should be submitted).

(2)(i) You must submit a subsequent Compliance report according to the schedule in § 63.2386(b) whenever any of the events in paragraph (d) of this section occur, as applicable.

(ii) Your subsequent Compliance reports must contain the information in § 63.2386(c)(1), (2), (3) and, as applicable, in § 63.2386(d)(3) and (4). If you are already submitting a subsequent Compliance report under § 63.2386(d), you do not need to submit a separate subsequent Compliance report for each storage tank that meets the conditions identified in paragraph (b) of this section (i.e., a single subsequent Compliance report should be submitted).

(3) For each storage tank that meets the conditions identified in paragraph (b) of this section, you must keep documentation, including a record of the annual average true vapor pressure of the total Table 1 organic HAP in the stored organic liquid, that verifies the storage tank is not required to be controlled under this subpart. The documentation must be kept up-to-date and must be in a form suitable and readily available for expeditious inspection and review according to § 63.10(b)(1), including records stored in electronic form in a separate location.

(c) For each transfer rack subject to this subpart that loads organic liquids but is not subject to control based on the criteria specified in Table 2 to this subpart, items 7 through 10, you must comply with the requirements specified in paragraphs (c)(1) through (3) of this section.

(1)(i) You must submit the information in § 63.2386(c)(1), (2), (3), and (10)(i) in either the Notification of Compliance Status, according to the schedule specified in Table 12 to this subpart, or a first Compliance report, according to the schedule specified in § 63.2386(b), whichever occurs first.

(ii)(A) If you submit your first Compliance report before your Notification of Compliance Status, the Notification of Compliance Status must contain the information specified in § 63.2386(d)(3) and (4) if any of the changes identified in paragraph (d) of this section have occurred since the filing of the first Compliance report. If none of the changes identified in paragraph (d) of this section have occurred since the filing of the first Compliance report, you do not need to report the information specified in § 63.2386(c)(10)(i) when you submit your Notification of Compliance Status.

(B) If you submit your Notification of Compliance Status before your first Compliance report, your first Compliance report must contain the information specified in § 63.2386(d)(3) and (4) if any of the changes specified in paragraph (d) of this section have occurred since the filing of the Notification of Compliance Status.

(iii) If you are already submitting a Notification of Compliance Status or a first Compliance report under § 63.2386(c), you do not need to submit a separate Notification of Compliance Status or first Compliance report for each transfer rack that meets the conditions identified in paragraph (b) of this section (i.e., a single Notification of Compliance Status or first Compliance report should be submitted).

(2)(i) You must submit a subsequent Compliance report according to the schedule in § 63.2386(b) whenever any of the events in paragraph (d) of this section occur, as applicable.

(ii) Your subsequent Compliance reports must contain the information in § 63.2386(c)(1), (2), (3) and, as applicable, in § 63.2386(d)(3) and (4). If you are already submitting a subsequent Compliance report under § 63.2386(d), you do not need to submit a separate subsequent Compliance report for each transfer rack that meets the conditions identified in paragraph (c) of this section (i.e., a single subsequent Compliance report should be submitted).

(3) For each transfer rack that meets the conditions identified in paragraph (c) of this section, you must keep documentation, including the records specified in § 63.2390(d), that verifies the transfer rack is not required to be controlled under this subpart. The documentation must be kept up-to-date and must be in a form suitable and readily available for expeditious inspection and review according to § 63.10(b)(1), including records stored in electronic form in a separate location.

In conducting the performance test, analyze samples collected as specified in EPA Method 18 at the outlet of the control device. Quantify the control device outlet emission concentration for the same organic HAP identified as present in the inlet or uncontrolled gas stream.

(ii) You may use ASTM D6420-99 (Reapproved 2004), Standard Test Method for Determination of Gaseous Organic Compounds by Direct Interface Gas Chromatography-Mass Spectrometry (incorporated by reference, see § 63.14), as an alternative to EPA Method 18 if the target concentration is between 150 parts per billion by volume and 100 ppmv and either of the conditions specified in paragraph (b)(2)(ii)(A) or (B) of this section exists. For target compounds not listed in Section 1.1 of ASTM D6420-99 (Reapproved 2004) and not amenable to detection by mass spectrometry, you may not use ASTM D6420-99 (Reapproved 2004).

(A) The target compounds are those listed in Section 1.1 of ASTM D6420-99 (Reapproved 2004), Standard Test Method for Determination of Gaseous Organic Compounds by Direct Interface Gas Chromatography-Mass Spectrometry (incorporated by reference, see § 63.14),; or

Total actual annual facility-level organic liquid loading volume means the total facility-level actual volume of organic liquid loaded for transport within or out of the facility through transfer racks that are part of the affected source into transport vehicles (for existing affected sources) or into transport vehicles and containers (for new affected sources) based on a 3-year rolling average, calculated annually.

(1) For existing affected sources, each 3-year rolling average is based on actual facility-level loading volume during each calendar year (January 1 through December 31) in the 3-year period. For calendar year 2004 only (the first year of the initial 3-year rolling average), if an owner or operator of an affected source does not have actual loading volume data for the time period from January 1, 2004, through February 2, 2004 (the time period prior to the effective date of the OLD NESHAP), the owner or operator shall compute a facility-level loading volume for this time period as follows: At the end of the 2004 calendar year, the owner or operator shall calculate a daily average facility-level loading volume (based on the actual loading volume for February 3, 2004, through December 31, 2004) and use that daily average to estimate the facility-level loading volume for the period of time from January 1, 2004, through February 2, 2004. The owner or operator shall then sum the estimated facility-level loading volume from January 1, 2004, through February 2, 2004, and the actual facility-level loading volume from February 3, 2004, through December 31, 2004, to calculate the annual facility-level loading volume for calendar year 2004.

(2)(i) For new affected sources, the 3-year rolling average is calculated as an average of three 12-month periods. An owner or operator must select as the beginning calculation date with which to start the calculations as either the initial startup date of the new affected source or the first day of the calendar month following the month in which startup occurs. Once selected, the date with which the calculations begin cannot be changed.

(ii) The initial 3-year rolling average is based on the projected maximum facility-level annual loading volume for each of the 3 years following the selected beginning calculation date. The second 3-year rolling average is based on actual facility-level loading volume for the first year of operation plus a new projected maximum facility-level annual loading volume for second and third years following the selected beginning calculation date. The third 3-year rolling average is based on actual facility-level loading volume for the first 2 years of operation plus a new projected maximum annual facility-level loading volume for the third year following the beginning calculation date. Subsequent 3-year rolling averages are based on actual facility-level loading volume for each year in the 3-year rolling average.

Transfer rack means a single system used to load organic liquids into, or unload organic liquids out of, transport vehicles or containers. It includes all loading and unloading arms, pumps, meters, shutoff valves, relief valves, and other piping and equipment necessary for the transfer operation. Transfer equipment and operations that are physically separate (i.e., do not share common piping, valves, and other equipment) are considered to be separate transfer racks.

* * * * *

Vapor balancing system means: (1) A piping system that collects organic HAP vapors displaced from transport vehicles or containers during loading and routes the collected vapors to the storage tank from which the liquid being loaded originated or to another storage tank connected to a common header. For containers, the piping system must route the displaced vapors directly to the appropriate storage tank or to another storage tank connected to a common header in order to qualify as a vapor balancing system; or (2) a piping system that collects organic HAP vapors displaced from the loading of a storage tank and routes the collected vapors to the transport vehicle from which the storage tank is filled.

Vapor collection system means any equipment located at the source (i.e., at the OLD operation) that is not open to the atmosphere; that is composed of piping, connections, and, if necessary, flow-inducing devices; and that is used for:

(1) Containing and conveying vapors displaced during the loading of transport vehicles to a control device;

(2) Containing and directly conveying vapors displaced during the loading of containers; or

(3) Vapor balancing. This does not include any of the vapor collection equipment that is installed on the transport vehicle.
