This action proposes revised default baseline values for reformulated gasoline and conventional gasoline under EPA's mobile source air toxics (MSAT) program. EPA's final rule, Control of Emissions of Hazardous Air Pollutants From Mobile Sources (66 FR 17230, March 29, 2001), requires that the annual average toxic performance of gasoline must be at least as clean as the average performance of the gasoline produced or imported during the period 1998-2000 (known as the “baseline period”). The baseline performance is determined separately for each refinery and importer, and the rule established default toxics baseline values for refineries that could not develop individual toxics baselines. The default toxics baseline values are based on the national average performance of gasoline during the baseline period. However, at the time of the final rule, gasoline toxics performance data were not yet available for the year 2000. Therefore, the final rule included regulations directing the EPA to revise the default toxics baseline values in the rule to reflect the entire 1998-2000 baseline period once the appropriate data became available. With this action, EPA is proposing to revise the default toxics baseline values for refineries and importers to reflect the national average toxics performance of gasoline during 1998-2000.

The regulations promulgated in the final rule, Control of Emissions of Hazardous Air Pollutants From Mobile Sources,[1] also known as the Mobile Source Air Toxics (MSAT) rule, require that the annual average toxics performance of gasoline produced or imported beginning in 2002 must be at least as clean as the average performance of the gasoline produced or imported during the three-year period 1998-2000 (40 CFR part 80, subpart J). The period 1998-2000 is called the baseline period. The average 1998-2000 toxics performance level, or baseline, is determined separately for each refinery and importer, except for those who comply with the anti-dumping requirements for conventional gasoline [2] on an aggregate basis, in which case the MSAT requirements for conventional gasoline must be met on the same aggregate basis. Toxics performance is determined separately for reformulated gasoline (RFG) and conventional gasoline (CG), in the same manner as the toxics determinations required by the reformulated gasoline [3] and conventional gasoline rules. An MSAT baseline volume is associated with each unique individual MSAT baseline value of a refinery or importer. The MSAT baseline volume reflects the average annual volume of such gasoline produced or imported during the baseline period.
To establish a unique individual MSAT baseline, EPA requires each refiner and importer to submit documentation supporting the determination of the baseline. Most refiners and many importers in business during the baseline period had sufficient data to establish an individual baseline for their refineries. However, a few refiners and importers did not have sufficient refinery production or imports during that period, and thus, based on the criteria specified in §§ 80.855(a) and 80.915(a), cannot establish a unique individual MSAT baseline. Refiners and importers without a unique individual MSAT baseline have the default baseline provided in § 80.855(b)(1) as their individual MSAT baseline. As discussed in the rule, the default baseline is based on the average toxics performance of gasoline produced and imported for use in the United States during the baseline period. At the time Start Printed Page 642of the rulemaking, year 2000 batch data from refiners and importers were not available, so EPA included in the regulations an estimate of the default baseline, as well as a requirement at § 80.855(b)(2) that EPA update this estimate to reflect the gasoline produced during the entire baseline period, including the year 2000. This proposed rule would complete that requirement.
EPA is proposing to update the MSAT default compliance baseline values, or “default baseline values,” in § 80.855(b)(1). For RFG, the proposed revised value is 26.78 percent reduction. For CG, the proposed revised value is 97.38 mg/mile. These revised values include the appropriate compliance margins. These values reflect the average nationwide [4] toxics performance of gasoline produced and imported during the period 1998-2000. The revised default toxics values were calculated using 1998, 1999, and 2000 toxics performance data that refiners and importers submitted to EPA under the RFG and anti-dumping programs. This toxics performance data was submitted for each batch of gasoline produced or imported. Batch toxics performance data most closely represents actual gasoline produced during the baseline period because the toxics performance is calculated from the batch's own set of fuel parameter values. We are also proposing that the revised values would be effective beginning with the 2005 annual compliance period. We believe that this start date provides affected parties sufficient lead time to prepare for the changes proposed today, yet does not further delay any environmental benefits associated with the baseline value revisions.
EPA considered two approaches for determining the revised MSAT default baseline values. Both used data submitted to EPA by refiners and importers under the RFG and anti-dumping programs. The first approach is the “Fuel Parameter” method. The volume-weighted average is calculated for fuel parameters values, each season, and the fuel parameter average is then used to determine the average toxics emissions. This is done separately for RFG and CG, for each baseline year for each refiner or importer. The Phase 2 version of the Complex Model [5] is used to calculate emissions. We then calculated the overall annual average toxics performance values for RFG and CG by volume-weighting the seasonal refiner and importer toxics performance values.
The second approach is the “Batch Performance” method. The toxics performance of each batch of CG and RFG is calculated based on each batch's fuel parameters. The batch by batch results are used to calculate the overall volume weighted average toxics performance for CG and RFG for the baseline period. The Batch Performance method is similar to the methodology used to develop the current default baseline values.
The national average 1998-2000 toxics performance determined by the two methods differs, as shown in Table 1. The RFG value determined by the Fuel Parameter method is slightly more stringent than that determined by the Batch Performance method. The RFG value by both methods is more stringent than the value currently in effect, as would be expected by the inclusion of year 2000 data. For the CG analysis, the results were mixed: compared to the value contained in the final rule, the Fuel Parameter method resulted in a more stringent value, and the Batch Performance method in a less stringent value. There are at least two reasons for this variation in the CG results. First, the CG default baseline contained in the final rule was based on batch information available just prior to the final rule (the best available data at the time). However, during the process of approving individual baselines, many errors in the submitted CG data were discovered. The resulting data set upon which the analyses for this proposal were based is a much different data set than that upon which the value contained in the final rule was determined, even apart from the inclusion of year 2000 data. Evaluation of oxygen use under the two methods (Fuel Parameter and Batch) is the second likely cause of discrepancy between this analysis and the final rule analysis. Averaging oxygen use, and accounting for different oxygenates, across all batches is probably less certain than accounting for oxygen use on a per batch basis.

Default Baseline Value** 94.64 93.39 97.38
* “Revised” refers to new values determined from data from the period 1998-2000

The Batch Performance approach for calculating the average toxics performance during 1998-2000 is a more appropriate methodology than the Fuel Parameter approach. The Batch Performance method better reflects and accounts for the actual gasoline (based on composition) that was in the market Start Printed Page 643during 1998-2000. Also, the Batch Performance method most closely resembles how refiners and importers determine compliance—on a batch by batch basis—by analyzing each batch and then determining the average toxics performance of the batches. This batch by batch calculation also avoids introduction of inaccuracy into the averaging process from the non-linear nature of the emissions model. Thus EPA is proposing that the revised MSAT default baseline values be based on the Batch Performance method.
EPA is proposing that the revised MSAT default baseline values proposed today be effective beginning with the 2005 annual compliance period. The CG revised default baseline value requires no consideration of lead time or feasibility as it is less stringent than the current value. The proposed revised RFG default baseline value is slightly more stringent than the current value, and does require lead time and feasibility considerations. While it was evident from our initial rulemaking that there would be an adjustment to the default baseline values, EPA believes it is reasonable to provide an appropriate amount of lead time for affected parties to consider and plan for compliance with the new standards. This primarily affects those parties subject to the default RFG baseline who are planning to produce or import RFG during 2005. EPA does not expect that those parties subject to the RFG default baseline who are not planning to produce or import RFG prior to 2006 will be significantly impacted by the revised value proposed today. Flexibilities provided by the MSAT program, such as deficit and credit carryover, are available to affected parties should they encounter compliance difficulties with the proposed revised standard in 2005.
As discussed, the increase in stringency of the MSAT default RFG standard is not unexpected, as the RFG toxics performance standard increased from 16.5% reduction for 1998 and 1999 to 21.5% reduction in 2000. Refiners and importers subject to the MSAT RFG default baseline could look to the RFG Survey [7] results for the periods 1998, 1999, and 2000 to estimate the likely change in the RFG default baseline value when year 2000 data was included. The year 2000 average RFG toxics performance calculated by the Batch Performance method is very close to the corresponding value estimated using the RFG survey data (29.1 and 30.1 % reduction, respectively). EPA believes the magnitude of the change in the RFG default baseline value is small enough that it can be addressed by small modifications in fuel composition during the course of the year.
Compliance with the gasoline sulfur requirements (§ 80.195) will further assist compliance with the proposed slightly more stringent RFG MSAT default baseline standard. Beginning in 2005, the gasoline sulfur regulations require that a refinery's average sulfur (across all its gasoline) not exceed 30 ppm, with a 300 ppm per-gallon cap in 2005 and an 80 ppm per-gallon cap beginning in 2006. During the MSAT baseline period, RFG sulfur averaged less than 200 ppm. Most affected parties will have to significantly reduce their gasoline pool sulfur levels through production or import of appropriate batches. In the Complex Model, changes in sulfur levels have a directionally consistent impact on toxics performance; a reduction in sulfur reduces toxics emissions, or in the case of RFG, increases the percent reduction in toxics emissions.
Further, EPA believes that delaying the implementation of the revised RFG default baseline reduces the small decrease in RFG toxic emissions that results from the revision proposed today. Thus, EPA believes that implementing the revised default baseline values beginning in 2005 is feasible and appropriate.
Today's proposed action would also correct, for calendar years 2002, 2003, and 2004, the RFG default MSAT value listed in the March 29, 2001, final rule. In that action, the compliance margin was incorrectly applied to the RFG average toxics reduction estimated for the period 1998-1999. We continue to believe that this compliance margin is appropriate based on the reasoning provided in the 2001 final rule. Thus, in addition to proposing the default toxics baseline that would apply beginning in 2005, today's action would also correct the RFG default toxics baseline applicable to 2002, 2003 and 2004, gasoline, by appropriately applying the compliance margin to the RFG average toxics reduction estimated in the 2001 final rule. Subtracting the 0.7 compliance margin from the 26.01% reduction performance estimate produces an RFG default baseline of 25.31% reduction.[8] Accordingly, for the 2002, 2003, and 2004, compliance periods, the default toxics baseline for RFG is a 25.31% reduction.
EPA included a discussion of the environmental and economic impacts of the MSAT rule in the March 2001 preamble to the rule. Today's proposal to update the default baseline values would not significantly change the environmental or economic analyses discussed in the final MSAT rule. However, EPA expects that there are likely minor impacts. First, because the proposed RFG default baseline value becomes slightly more stringent, there may be some cost to affected parties to comply with this revised value over the current value. However, as discussed above, it was very clear from the final rule that the default values would be revised. Because of the increase in the RFG toxics performance standard in 2000, and the fact that the reason for the revision to the MSAT default baseline was primarily to include year 2000 data, one could reasonably expect that the revised RFG value would be more stringent than that included in the final MSAT rule. With this slight increase in stringency will likely come a small increase in environmental benefits compared to the current standard. However, it is difficult to estimate the full impact (both economic and environmental) since most of those subject to the MSAT default RFG baseline do not import or produce RFG on a regular basis or do not produce significant quantities of RFG or may never produce RFG. Based on 2003 compliance reports, we estimate that about 40% of the RFG suppliers (refiners and importers) are subject to the MSAT default baseline, and none of those are considered small refiners or importers. Additionally, we estimate that these entities supplied less than 10 percent of the RFG volume.
The change in the CG default baseline value may result in an increase in emissions compared to the current standard. Given the discrepancy in CG data quality between the data used in the baseline calculation in the final rule and in this proposal, it is difficult to fully determine the environmental impact of this change. Most of those subject to the CG default baseline are Start Printed Page 644importers or blenders who do not produce or import large quantities of CG and/or who produce or import on an irregular basis. The bulk of the CG volume is subject to an individual MSAT standard. Thus, for the total pool of CG, the environmental effect of this change in the default baseline is likely to be small.

If you would like to present testimony at a public hearing, we ask that you notify the contact person listed above at least ten days beforehand. You should estimate the time you will need for your presentation and identify any needed audio/visual equipment. We suggest that you bring copies of your statement or other material for the EPA panel and the audience. It would also be helpful if you send us a copy of your statement or other materials before the hearing.
We will arrange for a written transcript of the hearing and keep the official record of the hearing open for 30 days to allow for the public to supplement the record. You may make arrangements for copies of the transcript directly with the court reporter.
Because the amendments in this proposed rule would not change the information collection requirements of the underlying MSAT rule, this action does not impose an information collection burden under the provisions of the Paperwork Reduction Act, 44 U.S.C. 3501 et seq. 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.
We have determined that approximately 25 refiners and importers meet the NAICS criteria described above and are subject to the MSAT default baseline for their reformulated gasoline. None of these entities produced or imported RFG during the MSAT baseline period or since then. Based on our knowledge of these refiners and importers, in fact, we would not expect any of them to produce or import RFG in the near future. Thus, we do not expect the revised RFG MSAT default value to adversely impact these small entities compared to the current RFG MSAT default value. In the event these refiners and importers choose to produce or import RFG, they will have had sufficient notice of the standard. Additionally, because the toxics determination is a function of many fuel parameters, as well as the volumes of the batches, the slight increase in stringency of the RFG MSAT default value should not pose a significant burden toward achieving compliance.
Although this proposed rule would not have a significant economic impact on a substantial number of small entities, the impact of this proposed rule will be reduced for small entities by various provisions in the MSAT rule. The MSAT rule contains deficit and credit carryforward provisions which provide compliance flexibility to regulated entities. Under these provisions, refiners and importers are allowed to carry a toxics deficit (indicating noncompliance with their MSAT standard) forward for one year, using credits generated in the prior or post years to make up the deficit. The underlying rule also includes a compliance margin to account for Start Printed Page 645ordinary variations in fuel quality. Because RFG toxics performance is a function of many fuel parameters, as well as the volumes of the batches, the slight increase (about 6%) in the stringency of the RFG MSAT default value should not pose a significant burden toward achieving compliance. Beginning in 2005, the requirement that a refiner's or importer's average gasoline sulfur level not exceed 30 ppm should provide additional assistance to regulated entities in complying with the MSAT requirements, since sulfur reductions also decrease toxics emissions, as determined by the Complex Model.
EPA has determined that this proposed rule does not contain a federal mandate that may result in expenditures of $100 million or more for State, local, and tribal governments, in the aggregate, or the private sector in any one year. Today's action would simply modify the original rule in a limited manner, and would not significantly change the original rule. Thus, today's proposed rule is not subject to the requirements of sections 202 and 205 of the UMRA.
EPA has also determined that this proposed rule contains no regulatory requirements that might significantly or uniquely affect small governments, because it would be applicable only to parties which produce or import gasoline.
This proposed rule does not have federalism implications. It 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 rule would amend existing regulatory provisions applicable only to producers and importers of gasoline and would not alter State authority to regulate these entities. The amendments will impose no direct costs on State or local governments. Thus, Executive Order 13132 does not apply to this proposed rule.
This proposed rule does not have tribal implications. It 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. The rule would amend existing regulatory provisions applicable only to producers and importers of gasoline and will impose no direct costs on State or local governments. Thus, Executive Order 13175 does not apply to this proposed rule.
This proposed rule is not subject to Executive Order 13045 because it is not economically significant as defined in Executive Order 12866. Nevertheless, as we explained in the preamble to the final MSAT rule in March 2001, we believe it is important to develop a better understanding of the effects on public health, including children's health. EPA is considering children's health issues in our Technical Analysis Plan.
This proposed rule is not subject to Executive Order 13211, “Actions Concerning Regulations That Significantly Affect Energy Supply, Start Printed Page 646Distribution, or Use'(66 FR 28355 (May 22, 2001)) because it is not a significant regulatory action under Executive Order 12866.
This proposed action does not involved technical standards. Therefore, EPA did not consider the use of any voluntary consensus standards.
The statutory authority for the fuels controls in today's proposed rule can be found in sections 202 and 211(c) of the Clean Air Act (CAA), as amended. Support for any procedural and enforcement-related aspects of the fuel controls in today's proposed rule, including recordkeeping requirements, comes from sections 114(a) and 301(a) of the CAA.
For the reasons set forth in the preamble, 40 CFR part 80 is proposed to be amended as set forth below:
2. Section 80.855 is amended by revising paragraphs (b)(1)(i) and (b)(1)(ii) to read as follows:
(i) For conventional gasoline, prior to January 1, 2005, 94.64 mg/mile; starting January 1, 2005, 97.38 mg/mile.
(ii) For reformulated gasoline, prior to January 1, 2005, 25.31 percent reduction from statutory baseline; starting January 1, 2005, 26.78 percent reduction from statutory baseline.

2. 40 CFR part 80, subpart E.
3. 40 CFR part 80, subpart D.
4. Excluding gasoline used in California and in other specified situations. See 40 CFR 80.820.
5. 40 CFR 80.45.
6. The 2001 final rule, at 80.915(h), listed the compliance margin for reformulated gasoline as −0.75. However, when EPA calculated the default baseline for RFG, it incorrectl7y added a value of 0.7 to the estimated average 1998-1999 gasoline toxics performance of 26.01% reduction (instead of subtracting 0.7). See MSAT Technical Support Document at p.157. Therefore, EPA incorrectly listed the default baseline value for RFG in the March 29, 2001 final rule as a 26.71% reduction (25.01 + 0.7), The correct estimated value for inclusion in the final MSAT rule should have been a 25.31% reduction (26.01 − 0.7). As discussed below, today's action corrects this mistake for the 2002-2004 compliance year. The average reformulated gasoline toxics performance calculated using data from the baseline period 1998 through 200 is a 27.48% reduction. Applying the compliance margin to this value results in a reformulated gasoline default compliance baseline value of 26.78% reduction (27.48 − 0.7).
7. The RFG Survey Association is an association of refiners, importers and blenders that performs surveys, or sampling, of reformulated gasoline at the retail level. This sampling is required under the reformulated gasoline regulations. These surveys collect and analyze samples from retail gasoline stations in the major cities where RFG is required. Each individual survey is conducted during a one-week period. Currently, over 150 surveys are conducted each year in federal RFG ares, with a total of more than 10,000 samples collected and analyzed. On the EPA website, EPA publishes estimates of the average toxics performance of gasoline in a given survey area based on the survey information.
