Final rule; amendments.
On April 8, 1987, the EPA promulgated the Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984. On March 27, 2000, the EPA issued a memorandum which stated that process tanks are “storage vessels” under the definition in the Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984. On May 26, 2000, the American Forest and Paper Association (AF&PA) filed a petition for judicial review of the March 27, 2000 memorandum. In this action, we are promulgating final rule amendments which were proposed pursuant to a settlement agreement with the American Forest and Paper Association (AF&PA) regarding their petition for judicial review of the March 27, 2000 memorandum. The final rule amendments will exempt certain storage vessels by capacity and vapor pressure, exempt process tanks, and add the process tank definition. The EPA is also amending the performance standards to exempt storage vessels that are subject to the National Emission Standards for Hazardous Air Pollutants: Solvent Extraction for Vegetable Oil Production.

I. What Is the Background for This Action?
The EPA proposed the 40 CFR part 60, subpart Kb, rules on July 23, 1984 (49 FR 29698) and promulgated them on April 8, 1987 (52 FR 11420). The performance standards implement section 111 of the CAA and are based on the Administrator's determination that volatile organic liquid (VOL) storage vessels cause or contribute significantly to air pollution which may reasonably be anticipated to endanger public health or welfare.
On March 27, 2000, the EPA issued a memorandum which stated that process tanks are “storage vessels” under the definition in the Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984.
On May 26, 2000, the AF&PA filed a petition for judicial review of the March 27, 2000 memorandum. The petitioner felt that the EPA had inappropriately expanded the scope of “storage vessels” with the interpretation in the 2000 memorandum. On August 23, 2001 (66 FR 44342), AF&PA and the EPA signed a settlement agreement that EPA would propose to amend subpart Kb to exclude from its applicability storage vessels that have a capacity less than 75 cubic meters (m3) or that contain a liquid with a maximum true vapor pressure below 3.5 kilopascals (kPa), and take final action on that proposal within a reasonable time.
On February 24, 2003 (68 FR 8574), we proposed amendments to subpart Kb pursuant to the agreement with AF&PA, as well as concerns raised by parties other than the petitioner. One party commented that in addition to the proposed amendments required by the settlement agreement, the EPA should exempt process tanks from subpart Kb. Another party commented that the regulatory overlap between subpart Kb and the National Emission Standards for Hazardous Air Pollutants: Solvent Extraction for Vegetable Oil Production (40 CFR part 63, subpart GGGG) should be addressed. Today's final rule amendments address the issues raised by AF&PA and other parties.
II. What Standards Are We Amending and How Does This Action Relate to the Overall Scope of the Subpart Kb Rule?
We are amending various provisions in 40 CFR part 60, subpart Kb, Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced After July 23, 1984. For further details, please refer to the February 24, 2003 proposed rule amendments (68 FR 8574). In doing so, we are indicating by necessary implication that subpart Kb applies to all industries where volatile organic liquid (as defined in § 60.111b(k)) is stored, and thus applies to other industries in addition to the petroleum and synthetic organic chemical manufacturing industries.
Exemption of Certain Storage Vessels by Capacity and Vapor Pressure. Today's action amends the final rule by eliminating recordkeeping requirements for storage vessels with a capacity less than 75 m3, for storage vessels with a capacity between 75 and 151 m3 storing liquid with vapor pressure less than 15 kPa, and for storage vessels with a capacity equal to or greater than 151 m3 storing liquid with vapor pressure less than 3.5 kPa. Put another way, the EPA is exempting from subpart Kb those storage vessels presently subject to recordkeeping requirements only.
Exemption of Process Tanks. The EPA is amending the final rule to exempt process tanks from subpart Kb. The EPA considered whether it was justified to amend subpart Kb to include process tanks within its scope, which would apply to new sources, that is, only to those process tanks for which construction, reconstruction, or modification commenced after the date of proposal of the action (see CAA sections 111(a)(2) and (b)(1)(B)).
Exemption of Storage Vessels Subject to the Vegetable Oil National Emission Standards for Hazardous Air Pollutants (NESHAP). The EPA contends that the overall emissions to the environment will not increase by exempting storage Start Printed Page 59330vessels from subpart Kb that are subject to the Vegetable Oil Production NESHAP, and that such exemption essentially amounts to avoiding duplicative regulation. The EPA is, therefore, exempting from subpart Kb all storage vessels that are subject to the Vegetable Oil Production NESHAP.
III. What Were the Comments Received on the Proposed Amendments?
Summary of Public Comments and Responses
This section of the preamble is a summary of the major public comments received in response to the proposed rule amendments, and changes resulting from the comments. A full report of all comments received and responses to the comments are in the “Standards of Performance for Volatile Organic Liquid Storage Vessels (Including Petroleum Liquid Storage Vessels) for Which Construction, Reconstruction, or Modification Commenced after July 23, 1984—Public Comments and Responses.” The document may be found in Docket ID No. OAR-2002-0046.
Comment: Two commenters recommended revising the definition of “process tank” to clarify that a vessel used within a process before material is transferred to a by-product storage vessel is considered to be a process tank. The commenters also recommended that the definition be revised to include tanks used to collect and recirculate solvents. One commenter suggested the EPA clarify that flare knockout vessels and vessels used for surge control for wastewater and/or sludge are process tanks. Another commenter requested the EPA clarify that pipeline emergency breakout tanks are process tanks, and another commenter requested the EPA clarify that vessels used for fermentation, distillation, mixing and blending, condensing, filtering, and extraction are process tanks.
Response: The EPA agrees that a vessel used within a process before material is transferred to a by-product storage vessel is considered to be a process tank. The definition of “process tank” in the final rule amendments reflects this view. The EPA considers vessels that receive and accumulate solvent or raw material from recovery processes to be storage vessels, not process tanks. Such vessels serve the same function as virgin solvent and raw material storage vessels, and some are located in tank farms with other storage vessels. The definition in the final rule amendments clarifies that “process tank” does not include such vessels. However, the definition also clarifies that vessels used within solvent and raw material recovery processes (that are not used for the ultimate storage of recovered liquids) are process tanks. The EPA agrees that flare knockout vessels and vessels used for surge control for wastewater and/or sludge are process tanks. The EPA also agrees that vessels used as described by one commenter (fermentation, distillation, etc.) are process tanks, and that the proposed definition of “process tank” would be interpreted to include such vessels. Finally, the EPA agrees that vessels used for pipeline surge control (not storage) are considered to be process tanks.
Comment: Several commenters recommended raising the proposed vapor pressure applicability criteria to the levels at which control is required. One of the commenters stated that the EPA's rationale for the proposed levels would also support raising the criteria to the levels at which control is required.
Response: The EPA disagrees that the rationale for the proposed applicability criteria also supports raising the levels to those at which control is required. The proposed applicability criteria would exempt tanks storing liquids with a vapor pressure significantly lower than the vapor pressure criteria for control. Regarding the vapor pressure at which recordkeeping of the stored liquid is required, the preamble to the 1987 final subpart Kb (49 FR 29711) states, “These vapor pressures should be high enough so that records would not be kept on liquids that could not, under reasonable circumstances, reach the maximum true vapor pressure cutoffs, but low enough so that records would be kept on most liquids that could reach the maximum true vapor pressure cutoffs.” This remains the EPA's position, and the EPA has, therefore, retained revised the applicability criteria as proposed.
Comment: One commenter urged the EPA to state that it will not seek to enforce subpart Kb for process tanks that have been constructed, reconstructed or modified after July 23, 1984 and before the date of the proposed amendments to subpart Kb.
Response: The EPA stated in the preamble to the proposed rule amendments that the 1998 interpretation of subpart Kb was definitive (in the sense that it was intended to set out the EPA's view and was written by an entity within the EPA with authority to do so) and, as such, can only be changed after notice-and-comment rulemaking. The EPA also stated that it would not be worthwhile to now propose to include process tanks under subpart Kb, and that the Agency was thus proposing to amend subpart Kb to exempt process tanks to codify the 1998 position. Therefore, the EPA will not be taking any enforcement action regarding the tanks described by the commenter.
Comment: One commenter urged the EPA to clarify its “enforcement posture” with respect to storage tanks in facilities other than the chemical and petroleum industries. The commenter stated several reasons for subpart Kb not applying outside the chemical and petroleum industries. The commenter stated that storage tanks outside the chemical and petroleum industries were not considered when determining the economic impacts of the proposed standards. The commenter also stated that the information collection request (ICR) for the standards was limited to the chemical and petroleum industries.
Response: The EPA stated in the preamble to the proposed rule why the text of the rule indicates that the rule's scope is not limited to the chemical and petroleum industries. The EPA also described the process by which a source category on the CAA section 111 priority list for regulation was revised (concurrently with the promulgation of subpart Kb) to include all volatile organic liquid storage. The priority list had previously included storage vessel source categories only for the petroleum industry and the synthetic chemical manufacturing industry, confirming what is already clear from the proposed rule's text—it applies to industries other than chemical and petroleum.
The commenter is correct that the economic analysis for subpart Kb did not include storage vessels in industries other than the chemical and petroleum industries. However, in the background information document for the proposed subpart Kb (EPA-450/3-81-003a), the amount of storage in industries outside the chemical and petroleum industries was estimated to be small enough (relative to storage in those industries) to be disregarded in the analysis.
The commenter is also correct that the supporting statement for the ICR for subpart Kb lists only the chemical and petroleum industries as respondents. Again, the EPA estimated that these industries contain the overwhelming majority of volatile organic liquid storage vessels. The list of respondents in the ICR supporting statement does not determine the applicability of subpart Kb; 40 CFR 60.110b determines applicability. Subpart Kb has such broad applicability that an exhaustive list of respondents would be difficult to develop. The Office of Management and Start Printed Page 59331Budget approved the current ICR for subpart Kb under terms which state that the EPA must submit a revised ICR, pursuant to the Paperwork Reduction Act and 5 CFR part 1320. The EPA intends to develop this expanded list during the next ICR renewal for subpart Kb.
In conclusion, the EPA interprets subpart Kb to apply to volatile organic liquid storage vessels, regardless of industry.
IV. Statutory and Executive Order Reviews
A. Executive Order 12866: Regulatory Planning and Review
Under Executive Order 12866 (58 FR 51735, October 4, 1993), the Agency 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 entitlements, 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.
It has been determined that the final rule amendments are not a “significant regulatory action” under the terms of Executive Order 12866 and are, therefore, not subject to OMB review.
B. Paperwork Reduction Act
This action does not impose any new information collection burden. This action exempts certain sources from 40 CFR part 60, subpart Kb. Therefore, it is likely that this action could only reduce the information collection burden. The OMB has previously approved the information collection requirements contained in the existing regulations under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq., and has assigned OMB control number 2060-0074 (EPA ICR No. 1132.06).
Copies of the ICR document(s) may be obtained from Susan Auby, by mail at the Office of Environmental Information, Collection Strategies Division; U.S. EPA (2822T); 1200 Pennsylvania Avenue, NW., Washington, DC 20460, by email at email@example.com, or by calling (202) 566-1672. A copy may also be downloaded off the internet at http://www.epa.gov/icr. Include the ICR or OMB number in any correspondence.
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 are listed in 40 CFR part 9 and 48 CFR chapter 15.
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 purposes of assessing the impacts of today's final rule amendments on small entities, a small entity is defined as: (1) A small business in the North American Industrial Classification System (NAICS) code 324 or 325 that has up to 500 employees; (2) a small business in NAICS code 424710 that has up to 100 employees; (3) 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 (4) 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 today's final rule amendments on small entities, I certify that this action will not have a significant economic impact on a substantial number of small entities. The EPA has determined that none of the small entities will experience a significant impact because the final rule amendments impose no additional regulatory requirements on owners or operators of affected sources. In fact, the final rule amendments should decrease the impacts on small businesses because they exempt some sources from regulation.
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, the EPA generally must prepare a written statement, including a cost-benefit analysis, for proposed and final rules with “Federal mandates” that may result in expenditures by State, local, and tribal governments, in the aggregate, or by the private sector, of $100 million or more in any 1 year. Before promulgating an EPA rule for which a written statement is needed, section 205 of the UMRA generally requires the 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 the 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 the 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 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.
The EPA has determined that the final rule amendments do not contain a Federal mandate that may result in Start Printed Page 59332expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any 1 year. The final rule amendments exempt certain sources from regulation. Thus, today's final rule amendments are not subject to the requirements of sections 202 and 205 of the UMRA.
E. Executive Order 13132: Federalism
Executive Order 13132 (64 FR 43255, August 10, 1999) requires the 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 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 amendments exempt certain sources from regulation. The final rule amendments impose no additional burden on sources, and the emissions reductions lost because of the exemptions are not significant. Thus, Executive Order 13132 does not apply to the final rule amendments.
In the spirit of Executive Order 13132 and consistent with EPA policy to promote communications between the EPA and State and local governments, the EPA specifically solicited comment on the proposed rule amendments from State and local officials.
F. Executive Order 13175: Consultation and Coordination With Indian Tribal Governments
Executive Order 13175 (65 FR 67249, November 9, 2000) requires the 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. The final rule amendments exempt certain sources from regulation. The final rule amendments impose no additional burden on sources, and the emissions reductions lost because of the exemptions are not significant. Thus, Executive Order 13175 does not apply to the final rule amendments.
The EPA specifically solicited additional comment on the proposed rule amendments from tribal officials.
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 the EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, the EPA must evaluate the environmental health or safety effects of the planned rule on children, and explain why the planned regulation is preferable to other potentially effective and reasonably feasible alternatives considered by the EPA.
The 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. Today's final rule amendments are not subject to Executive Order 13045 because they are based on technology performance, not health or safety risks. Furthermore, the final rule amendments have been determined not to be “economically significant” as defined under Executive Order 12866.
H. Executive Order 13211: Actions That Significantly Affect Energy Supply, Distribution, or Use
I. National Technology Transfer and Advancement Act
Section 12(d) of the National Technology Transfer and Advancement Act of 1995 (NTTAA), Public Law 104-113, 12(d) (15 U.S.C. 272 note), directs the EPA to use voluntary consensus standards in its regulatory activities unless to do so would be inconsistent with applicable law or otherwise impractical. Voluntary consensus standards are technical standards (e.g., materials specifications, test methods, sampling procedures, and business practices) that are developed or adopted by voluntary consensus standards bodies. The NTTAA directs the EPA to provide Congress, through OMB, explanations when the Agency decides not to use available and applicable voluntary consensus standards.
The final rule amendments do not involve technical standards. Therefore, the EPA is not considering the use of any voluntary consensus standards.
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. The EPA will submit a report containing this rule 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 rule 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 October 15, 2003.Start List of Subjects
