Environmental Protection Agency (EPA).
The EPA is approving revisions to the Albuquerque/Bernalillo County carbon monoxide (CO) State Implementation Plan (SIP) under the Federal Clean Air Act as Amended in 1990 (the Act). On February 4, 1999, the Governor requested EPA approval of a revision to the CO maintenance plan and motor vehicle emissions budgets covering 1996 to 2006, and the establishment of a CO motor vehicle emissions budget for the year 2010. The EPA initiated the approval process in two rule makings, the first for revisions to the CO maintenance plan and motor vehicle emissions budgets covering 1996 to 2006, and the second action to establish a CO motor vehicle emissions budget for the year 2010. This action is a final approval of both actions; revisions to the CO maintenance plan, and the CO Motor Vehicle Emissions Budget for 1996, 1999, 2002, 2005, 2006, and 2010. These CO Motor Vehicle Emissions Budgets are for transportation conformity purposes.
This rule is effective on May 24, 2000.
Copies of documents relevant to this action are available for public inspection during normal business hours at the following locations. Anyone wanting to examine these documents should make an appointment with the appropriate office at least two working days in advance.

Throughout this document wherever “we,” “us,” or “our” is used, we mean the EPA.
1. What Action Is EPA Taking?
The EPA is promulgating final approval of revisions to the Albuquerque CO maintenance plan. The original plan was approved in 1996 (61 FR 29970). In a document published December 20, 1999, the EPA published a direct final approval of revisions to the CO maintenance plan and related conformity budgets (64 FR 71027), with a companion proposed rule (64 FR 71086). The companion proposed rule was published in the event we received adverse comments, which we did. The direct final rule was withdrawn on February 14, 2000 (65 FR 7290). That document indicated that final action would be forthcoming.
The EPA also proposed approval of a Motor Vehicle Emissions Budget Start Printed Page 33456(MVEB) for 2010 for the CO maintenance area. That notice was published on February 29, 2000, beginning a 30 day public comment period (65 FR 10437). No comments were received on this proposed action.
Today's action is final approval and promulgation of both actions.
2. What Is Being Approved?
First, we are approving revisions to the CO maintenance plan's emission inventory for the nonattainment area. The following table summarizes the emission inventory for Albuquerque.
The EPA is also approving a series of MVEB's for the region, including a MVEB for the year 2010, which is beyond the current 10 year maintenance plan. These approved MVEB's are as follows:
3. How Will These MVEB's Be Used?
These MVEB's will be used for transportation conformity purposes, replacing the budgets in the original maintenance plan. The five year Transportation Improvement Program (TIP) and 20 year transportation plans for the Albuquerque region and corresponding emissions from on-road vehicles cannot surpass the above budgets.
4. When Is EPA's Approval Effective?
This action concerns only approval of the revised maintenance plan and MVEB's. Since December of 1999, the Albuquerque area has been in a conformity lapse, during which time certain transportation projects cannot be approved, accepted, or funded. The EPA is making this action effective upon publication to facilitate the conformity process.
The EPA reminds all parties that this document does not end the conformity lapse. The EPA, FHWA, State, and local planning agencies are working to complete the conformity process. The final conformity determination will be made by the FHWA.
Under the Administrative Procedures Act (APA), 5 U.S.C. 553(d)(3), agency rule makings may take effect before 30 days after the date of publication in the Federal Register if an agency has good cause to mandate an earlier effective date. It's the EPA's position that approving the necessary budgets as soon as possible, in the interest of facilitating the end of the conformity lapse, is cause to support making this action taking effect on publication.
5. What Comments Did EPA Receive to the Direct Final Notice?
Several parties stated that the Albuquerque Environmental Health Department (AEHD) is inverting the conformity process by setting a MVEB budget to fit a transportation plan. One party stated that the AEHD elected to revise the maintenance plan budget when the transportation plans could not conform. The party further stated that there is no data to show that the increase in VMT being incorporated into the budget is due solely to the unexpected growth in population.
The Clean Air Act as Amended in 1990, hereafter referred to as “the Act,” does not prohibit that maintenance areas review and revise their maintenance plans. As long as areas demonstrate continued maintenance, areas may revise them at their discretion, in accordance with the requirements of the Act, EPA's rules, and applicable guidance. Many areas revise them to estimate, more accurately, emissions that have grown at a rate different than the rate assumed in the original maintenance plan. All maintenance plans are revised after eight years, extending them an additional ten years. The AEHD elected to revise several elements of the inventory to make it more accurate. All of the emissions categories were revised as a result of this review.
Similarly, the Act allows areas to revise their Motor Vehicle Emissions Budget, so long as the area demonstrates they will maintain the standard. The revision submitted to the EPA shows total emissions in the area will remain at or below the emissions quantified in the attainment year. This constitutes an acceptable demonstration of continued attainment of the CO standard. (See the Act section 110, see also the preamble to the conformity rule at 58 FR 62196 on how to revise the budget and see 40 CFR 93.118).
The party alleged that the AEHD incorporated inappropriate assumptions used in the transportation model into the mobile modeling used to support the SIP revision. The party objected to straight-line interpolation of VMT levels as an inappropriate technique to estimate emissions.
The EPA provided for interpolation as an acceptable method of estimating emissions for regulatory purposes in guidance documents for completing SIP's. Specifically, the EPA guided planning agencies to use interpolation to estimate emissions for projected inventories, where it would be too costly and time-consuming to generate Start Printed Page 33457analyses for the interim years within a specified time period. The EPA issued this guidance for VMT growth factors (Procedures for Preparing Emissions Projections, 1991, page 29), and speeds (Procedures for Emission Inventory Preparation, 1992, page 31), and therefore, emissions.
In the case of Albuquerque, the MPO projected VMT for 1995, 2000, 2005, and 2010 using their transportation model, and per EPA guidance, calibrated the model using Highway Performance Measurement System (HPMS)-based factors. Since the maintenance plan was required to begin in 1996 and conclude in 2006, the AEHD used interpolation to determine the appropriate emissions for interim years. This is acceptable under EPA guidance.
The EPA reviewed the other Mobile5a inputs that represent assumptions about local conditions. It is EPA's position that these assumptions are reasonable and represent the best information currently available.
The party stated that the AEHD incorrectly estimated the impact of Big-I construction on vehicle speeds during construction, and VMT on alternative routes due to construction.
The AEHD is not required to quantify and incorporate the impact of construction in their MVEB in the SIP, because the impact of such construction is considered temporary. Emission inventory guidance does not instruct areas to quantify mobile emissions at the level of discrete construction projects.
We would point out that we cannot make an exception for a violation of the standard that could be attributed to temporary traffic conditions related to construction. While the MVEB does not have to include these temporary emissions, we do support the efforts of the AEHD and other agencies to mitigate them during the construction phase to avoid possible violations.
The party alleged that the AEHD used the 2010 roadway network to calculate emissions for the 2006 projections.
The proposed revision does not use the 2010 road network as the basis for determining VMT and then emissions in 2006. The projections for 2006 were based on interpolation between the two years for which the AEHD conducted VMT and emissions analysis using the more direct method of estimation. This method used complete street inventories, as they are expected to be in 2005 and 2010. Interpolation between these years allocates growth in VMT and emissions to each year during the period being studied. This does not mean that the impact of all road improvements scheduled to take place between 2005 and 2010 are being used to calculate emissions in 2006. As mentioned in a previous response, this interpolation technique is acceptable under EPA guidance.
The party stated that the AEHD used travel demand management programs (TDM's) or transportation control measures (TCM's) to reduce VMT used to set the emissions budget, even though the TDM's and TCM's do not have designated sources of funding and are not in the federally approved SIP.
The AEHD did not use any TCM's or TDM's to calculate the base emission inventory, project future inventories, or set the corresponding MVEB's. The AEHD used VMT projections provided to them by the Middle Rio Grand Council of Governments, the authorized MPO in the area. In a letter dated March 26, 1997, the AEHD specifically requested that the MPO not use any VMT reduction programs in the analysis they were to submit. The City's revision package submitted to the EPA included a summary of the VMT calculation methodology written by the MPO, dated September 11, 1997. That summary stated that the MPO did not use any VMT mitigation programs in the VMT estimates that they were providing. These estimates were then used in the inventory process.
The party referred to measures used to mitigate VMT growth in the effort to meet the MVEB. Those measures were not in the SIP revision, but were incorporated into the conformity analysis, as permitted under the transportation conformity rule. The conformity analysis is under review by the EPA. After review and comment by the EPA, FHWA issues its determination on conformity.
The party alleged that population was attributed to areas that will not have road access until after 2020.
The EPA would remind the party that the action is for approval of the maintenance plan to 2006, and the MVEB to 2010. The EPA reviewed maps available to the general public (“tiger” maps generated on April 28, 2000, from http://www.census.gov) at the U.S. Census Bureau web site of the referenced areas, and found road access to these areas.
The party stated that the road improvements from the Big I project would induce changes in trip patterns, traffic patterns, and speed that were not adequately captured in the modeling.
The model used by the MPO is appropriate and able to represent these changes. It is EPA's position that the MPO followed appropriate guidance in using the model to project changes in VMT and speed that result from transportation system improvements, the kind of changes in VMT the model was designed to measure.
The party alleged that compliance with the Inspection and Maintenance (I/M) program and anti-tampering enforcement rates were too high. The party said that a 95 percent compliance rate was too high, and the AEHD should have used 90 percent compliance.
The AEHD based their assumption on the national default rate, 96 percent, for approved I/M programs. The AEHD reduced the compliance rate from 96 to 95 percent to be slightly more conservative than the national compliance factor. The EPA receives and reviews periodic summary reports for the program, and finds the assumption reasonable.
The party stated that the AEHD used national default fleet mix and national default mileage accrual rates, when they should have developed their own fleet mix and mileage rates from the I/M program.
Agencies using the Mobile model may use EPA's national default values for these model inputs (See Mobile 5 Users manual). Although the EPA acknowledges that data generated locally is likely to reflect local conditions more accurately, this is at the discretion of the planning agencies. EPA's default values are acceptable for areas that elect not to develop their own, until the EPA can update the model and related default values.Start Printed Page 33458
The party objected to setting urban and rural local road speeds to a constant 25 and 20 miles per hour.
The modeling does reflect that the MPO set traffic speed on all urban local roads to an average of 25 miles per hour, and traffic on rural local roads to average 20 miles per hour. An assumption had to be made because the HPMS does not provide data on local roads. For all other road categories, the model employs actual field data to calibrate speeds. The assumption of 20 and 25 miles per hour on local roads was reasonable, and resulted in higher emission factors than such factors for any other road class. The proportion of all traffic on local roads was about ten percent. Local planning agencies are left to make reasonable judgments to estimate speed on these roads. In EPA's opinion, these are reasonable assumptions.
The EPA further analyzed this issue by comparing the VMT and speed data used in the SIP to the data used in the transportation plans now under conformity review. The MPO used the same projected VMT and speed estimates for this SIP, and the corresponding transportation plan and TIP. Since the MPO used identical numbers for both analyses, the impact of the traffic speed assumption vis-a-vis another assumption is minimal.
The party alleges that the AEHD modeled lower speeds and lower emissions by using a speed enforcement program, without documentation to support including such a program.
The projected speeds used to compute the emissions in the SIP revision decreased slightly over time. The EPA reviewed the emission projections in detail and concluded that lower speeds are more a product of increased VMT. Speed estimates on such roadway segments are the product of the transportation model. As pointed out above, the Albuquerque MPO appropriately employed an endorsed model that, under an assumption of continued VMT growth, would induce lower speeds in future years.
The Party contends that the Albuquerque vehicle fleet is not as clean as the national average. The party also stated that the model runs did not differentiate the fleet mix by roadway class.
Under EPA guidance, the AEHD can rely on national default values for vehicle fleet mix and vehicle mileage accrual rates. When the model uses defaults for the mix and mileage rates, the fleet mix by roadway class also becomes an implicit default variable. (Mobile 5 Users Guide, sec. 2.2.2, and 2.2.3).
The Party contends that the goal for decreasing reliance on the Single Occupant Vehicle (SOV) was relaxed from the 2015 plan to the 2020 plan.
Beyond a demonstration of continued maintenance, the issue is not germane to this action. Local agencies have the discretion to elect how they will maintain the standard. The EPA encourages areas to take actions to reduce reliance on the SOV. However, AEHD's revision demonstrates continued attainment with credible analysis, which meets the requirements of the Act.
The Party contends that the 1.4 billion dollars needed to implement the 2020 Plan has not been secured, because the Regional Transit Authority was not granted taxing authority. The Party claims that a line item of $100 million dollars in the 2000 to 2005 plan to purchase busses was deleted, but remained in the first five years of the 2020 plan.
The comment is not germane to this SIP action, because transit improvements were not employed in generating the VMT projections used by the AEHD to project emissions for the inventory and MVEB. The issues of fiscal constraint are beyond the scope of this SIP approval action and should be addressed in the transportation conformity process.
The Party alleges that building additional road capacity produces more VMT, but that the model is inadequate to capture this. The party contends that the model predicts lower emissions as a result of road expansion, when the model should predict more emissions.
The MPO used an endorsed transportation model, currently the best tool available to planning agencies. All areas that employ models must show that their model predicts, with reasonable accuracy, the impact of transportation improvements. This process, called calibration and validation, was performed in order for the modeling results to be acceptable. The EPA encourages the party to bring their concerns into the conformity process through the established public participation process.
The Party states that they regularly commute by bicycle, and observes fewer bicycles on the road despite the increase in facilities. The party says this observation contradicts the assumption of the MPO that increased bicycle ridership will reduce VMT.
The assumption of increased bicycle ridership was not used to estimate VMT, and therefore did not affect emissions in the SIP MVEB.
The Party asked if recent ozone readings presage nonattainment of ozone, that would result through a greater allowance for CO emissions.
The AEHD is not required to demonstrate maintenance of the ozone standard in order to revise their CO maintenance plan in the CO SIP. The concept of conformity was created in the Act to insure that the growth of VMT and on-road emissions did not interfere with attainment and maintenance of national standards. Any actions that AEHD or EPA might take to continue ozone maintenance must be under the legal framework established for control of ozone precursors. Currently there is no monitoring data that indicate ozone violations. If evidence ever shows there are violations, the EPA can issue a SIP call for the area to submit an ozone SIP. An EPA SIP call and/or a designation to ozone nonattainment would, in fact, compel the area to perform conformity analysis for ozone precursors.
The EPA is acting on a revision to the CO SIP, which meets the requirements for such a revision.
The Party asked what would prevent the AEHD from asking for another revision to the MVEB, in three or four years?
The AEHD could request another revision to the MVEB at a later date. The AEHD must extend the initial maintenance plan an additional ten Start Printed Page 33459years before the initial maintenance plan expires in 2006. However, basin-wide emissions must remain below 389 tons per day as established in the maintenance plan.
The Party asks that the EPA issue a conditional approval, with the condition that the transportation model be improved. The Party also requested that approval be conditioned on a commitment from the MPO to a balanced transportation system.
The EPA's review and approval is based on whether the Albuquerque area can maintain the CO standard and prevent violations of the CO standard with a revised MVEB (see section 110 of the Act). It's EPA's opinion that AEHD successfully demonstrated that Albuquerque will continue to maintain the CO standard with a revised MVEB.
6. What Comments Did EPA Receive to the February 28, 2000, Proposed Rule?
The EPA received no comments to that proposed rule.
7. Will Albuquerque have to Revise the Inventory and MVEB's Again?
Albuquerque must revise the maintenance plan again by 2004, to extend the maintenance plan an additional 10 years from the final year of the current plan, 2006. This will cover the years from 2006 to 2016. This may result in changes to the 2006, and 2010 budgets established today. Regardless, the area must remain below the total level of CO emissions established in the maintenance plan to demonstrate continued attainment of the standard.
II. Final Action
The EPA is approving revisions to the Albuquerque/ Bernalillo County carbon monoxide (CO) State Implementation Plan (SIP). This action is a final approval of revisions to each of the categories of the CO emissions inventory, the basin-wide total of CO emissions for the area, and the CO Motor Vehicle Emissions Budgets for 1996, 1999, 2002, 2005, 2006, and 2010. The CO Motor Vehicle Emissions Budgets must be used for transportation conformity purposes once this approval is effective.
III. Administrative Requirements
A. Executive Order 12866
The Office of Management and Budget (OMB) has exempted this regulatory action from Executive Order 12866, entitled “Regulatory Planning and Review.”
Executive 13132, entitled “Federalism” (64 FR 43255, August 10, 1999) revokes and replaces Executive Order 12612, “Federalism,” and Executive Order 12875, “Enhancing the Intergovernmental Partnership.” Executive Order 13132 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.” Under Executive Order 13132, EPA may not issue a regulation that has federalism implications, that imposes substantial direct compliance costs, and that is not required by statute, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by State and local governments, or EPA consults with State and local officials early in the process of developing the proposed regulation. The EPA also may not issue a regulation that has federalism implications and that preempts State law unless the Agency consults with State and local officials early in the process of developing the proposed regulation.
This final rule 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, because it merely approves a State rule implementing a Federal standard, and does not alter the relationship or the distribution of power and responsibilities established in the Act. Thus, the requirements of section 6 of the Executive Order do not apply to this rule.
Executive Order 13045, entitled “Protection of Children from Environmental Health Risks and Safety Risks” (62 FR 19885, April 23, 1997), applies to any rule that: (1) Is determined to be “economically significant” as defined under Executive Order 12866, and (2) concerns an environmental health or safety risk that EPA has reason to believe may have a disproportionate effect on children. If the regulatory action meets both criteria, 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.
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 Order has the potential to influence the regulation. This final rule is not subject to Executive Order 13045 because it approves a State program.
Under Executive Order 13084, EPA may not issue a regulation that is not required by statute, that significantly or uniquely affects the communities of Indian tribal governments, and that imposes substantial direct compliance costs on those communities, unless the Federal government provides the funds necessary to pay the direct compliance costs incurred by the tribal governments, or EPA consults with those governments. If EPA complies by consulting, Executive Order 13084 requires EPA to provide to the OMB, in a separately identified section of the preamble to the rule, a description of the extent of EPA's prior consultation with representatives of affected tribal governments, a summary of the nature of their concerns, and a statement supporting the need to issue the regulation. In addition, Executive Order 13084 requires EPA to develop an effective process permitting elected officials and other representatives of Indian tribal governments “to provide meaningful and timely input in the development of regulatory policies on matters that significantly or uniquely affect their communities.”
Today's rule does not significantly or uniquely affect the communities of Indian tribal governments. This action does not involve or impose any requirements that affect Indian tribes. Accordingly, the requirements of section 3(b) of Executive Order 13084 do not apply to this rule.
E. Regulatory Flexibility Act
The Regulatory Flexibility Act, 5 U.S.C. 600 et seq., generally requires an agency to conduct a regulatory flexibility analysis of any rule subject to notice and comment rule making requirements unless the agency certifies that the rule will not have a significant Start Printed Page 33460economic impact on a substantial number of small entities. Small entities include small businesses, small not-for-profit enterprises, and small governmental jurisdictions. This final rule will not have a significant impact on a substantial number of small entities because SIP approvals under section 110 and subchapter I, part D of the Act do not create any new requirements but simply approve requirements that the State is already imposing. Therefore, because the Federal SIP approval does not create any new requirements, I certify that this action will not have a significant economic impact on a substantial number of small entities. Moreover, due to the nature of the Federal-State relationship under the Act, preparation of a flexibility analysis would constitute Federal inquiry into the economic reasonableness of state action. The Act forbids EPA to base its actions concerning SIPs on such grounds. See Union Electric Co., v. U.S. EPA, 427 U.S. 246, 255-66 (1976); 42 U.S.C. 7410(a)(2).
F. Unfunded Mandates
Under section 202 of the Unfunded Mandates Reform Act of 1995, signed into law on March 22, 1995, EPA must prepare a budgetary impact statement to accompany any proposed or final rule that includes a Federal mandate that may result in estimated annual costs to State, local, or tribal governments in the aggregate; or to private sector, of $100 million or more. Under section 205, EPA must select the most cost-effective and least burdensome alternative that achieves the objectives of the rule and is consistent with statutory requirements. Section 203 requires EPA to establish a plan for informing and advising any small governments that may be significantly or uniquely impacted by the rule.
The EPA has determined that the approval action promulgated does not include a Federal mandate that may result in estimated annual costs of $100 million or more to either State, local, or tribal governments in the aggregate, or to the private sector. This Federal action approves pre-existing requirements under State or local law, and imposes no new requirements. Accordingly, no additional costs to State, local, or tribal governments, or to the private sector, result from this action.
G. Submission to Congress and the Comptroller General
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.
A major rule can not 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). This rule will be effective May 24, 2000.
H. Petitions for Judicial Review
Under section 307(b)(1) of the Act, petitions for judicial review of this action must be filed in the United States Court of Appeals for the appropriate circuit by July 24, 2000. Filing a petition for reconsideration by the Administrator of this final rule does not affect the finality of this rule for the purposes of judicial review nor does it extend the time within which a petition for judicial review may be filed, and shall not postpone the effectiveness of such rule or action. This action may not be challenged later in proceedings to enforce its requirements. See section 307(b)(2).Start List of Subjects
