Regulation of Fuels and Fuel Additives: Adjustments to Individual 
Baselines for the Reformulated Gasoline and Anti-Dumping Programs

AGENCY: Environmental Protection Agency (EPA).

ACTION: Final rulemaking.

-----------------------------------------------------------------------

SUMMARY: Under the Clean Air Act (CAA or the Act), as amended in 1990, 
the Environmental Protection Agency (EPA or the Agency) promulgated 
anti-dumping regulations for conventional gasoline, that is, gasoline 
not certified as reformulated gasoline (RFG). These regulations require 
that conventional gasoline not be more polluting than it was in 1990. 
They also include provisions for the development of individual refinery 
baselines. The regulations also include provisions which allow a 
refinery to obtain an adjusted baseline under certain, limited 
circumstances. Today's regulations modify the requirements of one 
baseline adjustment and specify the requirements of two new baseline 
adjustments.
    Specifically, today's rulemaking modifies the requirements for 
obtaining a baseline adjustment due to the production of JP-4 jet fuel 
in 1990. This rule also allows a baseline adjustment for refiners who 
are now unable to acquire extremely sweet crude oil (that is, crude oil 
relatively low in sulfur) that had been available in 1990 and from 
which the gasoline used to develop a 1990 individual baseline was 
obtained. Finally, this rule allows a baseline adjustment for 
refineries which have both extremely low baseline sulfur and olefin 
levels.
    The criteria for obtaining any baseline adjustment are stringent. 
As a result, only those refineries which would experience a severe 
economic burden due to the regulations are allowed the relief provided 
by a baseline adjustment. Since few refineries qualify for these 
adjustments and requiring compliance without a baseline adjustment 
would be of minimal benefit to the environment, the environmental 
impact of allowing the baseline adjustments is negligible.

DATES: This rule will be effective on April 22, 1997.

ADDRESSES: Materials relevant to this final rulemaking (FRM) are 
contained in Public Docket No. A-95-03. Materials relevant to the RFG 
final rule are contained in Public Dockets A-91-02 and A-92-12. These

III. Introduction

    The standards that a refiner must comply with for certain aspects 
of the reformulated and conventional gasoline regulations are based on 
the refiner's individual baseline.1 An individual baseline is the 
set of fuel parameter values, emissions values, and component volumes 
which represent the quality and quantity of the refiner's 1990 
gasoline. (See 40 CFR 80.91.) EPA's regulations establish requirements 
for developing an individual baseline. For special situations, the 
Agency has allowed the baseline fuel parameters, emissions values, and 
component volumes to be adjusted. Such situations have included 
unforeseen downtime of a gasoline blendstock producing unit, non-annual 
maintenance, work-in-progress, and JP-4 jet fuel production.
---------------------------------------------------------------------------

    \1\ In general, the anti-dumping provisions apply to refiners or 
importers of conventional gasoline. The baseline adjustment 
provisions finalized in today's notice, however, are applicable only 
to refiners and their refineries.
---------------------------------------------------------------------------

    This FRM allows baseline adjustments for three situations where 
parties would suffer an extreme economic burden due to the original 
regulations if relief were not granted. Specifically, this rule (1) 
Revises the requirements for a baseline adjustment due to the 
production of JP-4 jet fuel in 1990, (2) provides an adjustment to the 
baseline sulfur values of certain refineries for instances where 
extremely sweet crude oil (which is no longer available) was used in 
1990 gasoline production, and (3) adds a provision for adjusting 
refinery baselines which have very low values for both sulfur and 
olefins.
    In general, for refiners who qualify for one or more of the 
baseline adjustments finalized today, EPA will apply the adjustments to 
gasoline produced in 1996. In the August 1995 Notice of Proposed 
Rulemaking (NPRM) EPA indicated that any adjustments finalized under 
this rulemaking would apply to a refiner's 1995 compliance 
determination. However, EPA cannot retroactively apply a rulemaking, 
even one that provides a measure of regulatory relief. Many refiners 
affected by today's rule received baseline adjustments under the stay 
promulgated at 60 FR 40006 (August 4, 1995). Because these refiners 
have the same adjusted baseline under the stay that they would receive 
as a result of today's action, they are unaffected by whether or not 
today's rule applies to 1995 compliance determinations. For those 
refiners who did not receive an adjusted baseline, EPA will consider 
this rule in its review of 1995 compliance determinations.

IV. JP-4 Baseline Adjustment

A. Introduction

    JP-4 jet fuel, the use of which is being phased out by the U.S. 
Department of Defense, was produced in 1990 by many refiners under 
contract with the Defense Department. Because refineries will most 
likely use the JP-4 blendstock in gasoline, the JP-4 fuel must first be 
processed through a reformer to increase its octane to suitable 
gasoline levels. Due to the high aromatic content of the reformer 
streams, the toxic emissions of the ``new'' gasoline (calculated using 
the Simple and Complex Models) will likely increase relative to the 
gasoline's 1990 values. In addition, it is possible that gasoline 
production will increase (relative to 1990 production) due to movement 
of blendstocks directly and indirectly from JP-4 to gasoline. The 
impact of the increase in aromatic content and/or additional volume due 
to JP-4 phase-out will affect certain refiners more than others.
    The December 1993 regulations 2 already provide for an 
adjustment to a refiner's individual baseline due to production of JP-4 
in 1990 if three criteria are met. These criteria were designed to 
ensure that the original adjustment would result in de minimis 
environmental impact and would remove the extreme burden on the 
refiner.3 First, under the original adjustment, JP-4 baseline 
adjustments are allowed only for refiners who do not or will not in the 
future produce RFG. If a refiner granted such an adjustment 
subsequently produces RFG, its conventional gasoline compliance will be 
subject to its original unadjusted baseline during the current 
averaging period and all subsequent years. Second, a JP-4 baseline 
adjustment is available primarily to qualifying single-refinery 
refiners. A multi-refinery refiner could also receive an adjustment if 
each of its refineries produced JP-4 in 1990 and if each refinery also 
meets the other requirements for obtaining the adjustment. Third, to 
receive an adjustment, the refiner is required to show that a 
significant burden would exist if no baseline adjustment was allowed. 
The original regulations require that the ratio of a refinery's 1990 
JP-4 production to its 1990 gasoline production must equal or exceed 
0.5 in order to be defined as a significant burden on the refiner.

    \3\ Alabama Power Company vs. Costle, 636 F.2d 323-357 (D.C. 
Cir. 1979).
---------------------------------------------------------------------------

    In the August 4, 1995 NPRM (60 FR 40009), EPA proposed modified 
provisions related to JP-4 baseline adjustments. These provisions were 
essentially the same as those contained in a direct final rulemaking 
(DFRM) which was published at 59 FR 36944, July 20, 1994.4 
Specifically, EPA proposed the following three conditions that would 
have to be met by a refiner who petitions for a baseline adjustment due 
to JP-4 production in 1990. The first condition applies to multi-
refinery refiners while the second and third

[[Page 9874]]

conditions apply to all refining companies.
---------------------------------------------------------------------------

    \4\ EPA withdrew this DFRM since EPA received adverse comments 
on the changes specified in the DFRM with regard to JP-4 baseline 
adjustments. As announced in the DFRM, such provisions would take 
effect only if no persons submitted adverse comments or requested an 
opportunity to comment. For more discussion, see the support 
document, ``Regulation of Fuels and Fuel Additives: Standards for 
Reformulated and Conventional Gasoline--Detailed Discussion and 
Analysis'', Air Docket A-95-03.
---------------------------------------------------------------------------

(1) The Qualifying Refiner Must Have Produced JP-4 at One or More of 
Its Refineries in 1990
    The original JP-4 baseline adjustment provisions for multi-refinery 
refiners require that each refinery must have produced JP-4 in 1990. 
This revision would allow a refiner to obtain this baseline adjustment 
even if only one of its refineries produced JP-4 in 1990 (and if the 
refiner and its refineries also meet the other criteria specified for 
this baseline adjustment). EPA believes it may use its discretion to 
provide relief for a multi-refinery refiner even if only one of the 
refiner's refineries produced JP-4 in 1990 (provided that the refiner 
or refinery meets the other requirements required for a JP-4 baseline 
adjustment). If a multi-refinery refiner qualifies for a baseline 
adjustment under this criterion, it must then calculate the adjusted 
baseline of the refinery(ies) which actually produced JP-4 in 1990 and 
determine its anti-dumping compliance on an aggregate basis.
(2) The Qualifying Refiner Must Have a 1990 JP-4 to Gasoline Ratio 
Greater Than or Equal to 0.15 (See Discussion Below Regarding JP-4 
Baseline Adjustment Ratio)
    (a) For each individual refiner, if all of its refineries produced 
JP-4 in 1990, the refiner may comply with the anti-dumping requirements 
on an individual or aggregate basis; or
    (b) On a refiner-wide basis, in which case the refiner must 
determine an individual baseline for each of its refineries but must 
comply with the anti-dumping requirements on an aggregate basis.
(3) The Qualifying Refiner Must Not Produce Reformulated Gasoline (RFG) 
at Any of Its Refineries Now or in the Future
    The comments received on this proposal are discussed below. None of 
the comments provided new information or supportive data. Therefore, 
EPA today finalizes this provision as proposed, for the reasons 
described in the NPRM.

B. General Comments on the Proposal

Summary of Comments
    Generally, many commenters felt the original eligibility 
requirements for receiving a JP-4 baseline adjustment are unnecessarily 
restrictive. They felt that EPA's overriding concern should be the 
impact of the baseline adjustments on the environment, and they 
suggested that most refineries meeting the JP-4 criteria operate in 
rural, clean air (i.e., attainment) areas.
    Several commenters opposed the regulation change, stating that it 
would be more equitable for all JP-4 producers to get an adjustment, 
regardless of ratio, aggregation, or RFG production. Commenters stated 
that this position is based on the fact that all JP-4 producers were 
meeting a market demand, and therefore should not be selectively 
penalized. Furthermore, these commenters felt that elimination of post-
1995 demand for JP-4 causes all baselines to be unrepresentative of 
current and future operations. Therefore the JP-4 phase-out and anti-
dumping regulations may have unintended adverse effects on the 
regulated community of former JP-4 suppliers. These commenters 
suggested that a better approach would be to allow an adjustment for 
all JP-4 producers, and allow refiners to rethink aggregation 
decisions. The commenters felt this would ``level the playing field'' 
and simplify the regulations.
Analysis and Conclusion
    EPA's authority to grant exceptions to this requirement of the CAA 
is very limited. EPA does not believe it is appropriate, given the 
applicable facts and this limitation, to allow adjustments for all JP-4 
producers. Exceptions to this requirement of the Act should only be 
allowed for cases of extreme regulatory burden with minimal 
environmental impact, and not all refiners who produced JP-4 in 1990 
are extremely burdened by the requirements of the RFG and anti-dumping 
programs. Today's action slightly broadens the JP-4 baseline adjustment 
criteria, but continues to allow adjustment only where extreme burden 
is demonstrated.

C. Comments on the Proposed Ratio of JP-4 Production to Gasoline 
Production

Summary of Comments
    Some commenters opposed the change in production ratio to 0.15, 
stating that the 0.15 ratio is arbitrary and that EPA has provided no 
evidence of hardship for the three or four refineries which would be 
affected. One commenter felt that if the environmental impacts are 
minimal at 0.15, they would be even less for those below the 0.15 
production ratio. They stated that as little as two percent JP-4 
production can be a significant aspect of refining operations; 
adjusting for production, this low percentage may have little impact on 
the baseline but would provide necessary relief for refiners who have 
experienced increasing levels of benzene and aromatics. Commenters also 
felt that refineries on the ``wrong side'' of the ratio will continue 
to argue for special exemptions; any ratio arbitrarily provides relief 
to some while denying it to others.
    Commenters also stated that it is impossible for the public to 
judge whether a hardship even exists. They felt that the ratio 
criterion is only one of several criteria which should be used to 
determine hardship. They argued that the regulation should not be 
limited to just one criterion, but rather it should include alternative 
tests for hardship. Several alternative criteria for determining 
hardship were suggested by commenters. One commenter suggested that EPA 
should evaluate the financial penalty of noncompliance relative to the 
refiner's size and profit to determine extreme burden. One commenter 
proposed that a straight production volume of 100,000 gallons of JP-4, 
rather than a jet fuel-to-gasoline production ratio, would be a more 
appropriate baseline adjustment criterion. In addition, commenters 
suggested that EPA should consider the historical pattern of JP-4 
production for a refinery, stating that a refinery that produces JP-4 
over a long period will have greater hardship converting that product 
to gasoline.
    Finally, it was suggested that EPA needs to recognize that the 
industry is capital-intensive and that refineries should be encouraged 
to make the necessary capital investments.
Analysis and Conclusion
    As stated before, in addition to minimal environmental impact, 
regulatory burden must also be considered before an exception to the 
regulations can be made, and a baseline adjustment allowed. As 
discussed in the December 1993 Regulatory Impact Analysis (RIA), the 
JP-4 to gasoline production ratio is the best measure found by EPA to 
estimate and quantify this burden. However, based on information 
received by EPA subsequent to the initiation of the RFG program, the 
original 0.5 ratio does not provide the relief intended by the Agency. 
Using industry data, EPA proposed a more appropriate ratio of 0.15, and 
stated that a few more (three or four) refineries could potentially 
benefit from this change in the ratio. Although EPA agrees with 
commenters that other means of showing extreme burden of the 
regulations may exist, EPA has not found any which seem as appropriate 
(particularly with respect to providing a quantitative means of 
establishing burden). Additionally, EPA believes that such alternative 
tests would be difficult to implement at this

[[Page 9875]]

stage in the baseline approval process. Finally, EPA believes that 
limiting this analysis to 1990 situations is most consistent with 
statutory structure.

D. Comments on the Aggregation and RFG Production Restrictions

    In the August 1995 NPRM, EPA proposed that a multi-refinery 
refiner, could qualify for a JP-4 baseline adjustment even if only one 
of its refineries produced JP-4 in 1990. However, that refiner would 
have to determine its compliance on an aggregate basis and could 
produce no RFG at any of its refineries. A detailed discussion of the 
basis of these requirements can be found in the support document for 
this rule, ``Regulation of Fuels and Fuel Additives: Standards for 
Reformulated and Conventional Gasoline-Detailed Discussion and 
Analysis,'' Air Docket A-95-03.
Summary of Comments
    Commenters supporting the proposed modifications to the regulation 
provided several points to support the changes. Primarily, they stated 
that without these changes, it would be impossible for a multi-refinery 
refiner to qualify for an adjustment. Thus, according to commenters, 
the regulation would not provide the relief intended by EPA. Some 
commenters supporting the proposed changes to the regulation endorsed 
the need for change in the aggregation requirements of the JP-4 
adjustment. Commenters felt that such requirements would further 
restrict the business decisions of a multi-refinery refiner.
    Many commenters addressed the RFG production restrictions placed on 
a refiner that receives a JP-4 adjustment. Commenters felt that 
prohibiting RFG production by these refiners may cause a refiner not to 
produce RFG for areas where it is needed. Also, commenters argued that 
some refiners who qualify for the JP-4 adjustment may have already 
produced RFG. These commenters felt that the environmental impact of 
allowing RFG production would be minimal.
    Analysis and Conclusion
    EPA is retaining the proposed requirement that a multi-refinery 
refiner qualifying for a JP-4 baseline adjustment, for which not all of 
its refineries produced JP-4 in 1990, must determine its compliance on 
an aggregate basis. Under the regulations promulgated today, such a 
refiner is able to obtain a JP-4 baseline adjustment because it has 
determined its JP-4 to gasoline ratio on an aggregate basis. EPA 
continues to believe that it is appropriate to thus require such a 
refiner to determine its anti-dumping compliance on an aggregate basis 
as well. A multi-refinery refiner for which each of its refineries 
meets the JP-4 baseline adjustment criteria individually may determine 
its compliance on an aggregate or non-aggregate basis.5
---------------------------------------------------------------------------

    \5\  However, as for all refiners, once the decision to 
determine compliance on an aggregate basis is made, compliance must 
be made on that basis for all future compliance periods.
---------------------------------------------------------------------------

    EPA continues to believe that prohibiting RFG production is a 
critical criteria for this baseline adjustment as it is the best way to 
ensure that no ``dumping'' will occur. EPA does not consider this 
requirement to be unduly restrictive.

E. Comments Regarding the Effect of JP-4 Production on Refinery 
Operation

Summary of Comments
    Several commenters, including both those supporting the regulation 
changes and those opposing them, stated that EPA should give full 
consideration to the effects of JP-4 production on refinery operations. 
These commenters pointed out that 1990 JP-4 production can limit 
gasoline production at a refinery, and that premium gasoline, the most 
profitable gasoline to produce, is most affected by baseline 
limitations. Commenters stated that JP-4 production limited small 
refiners with low conversion configurations who could not fractionate 
excess gasoline into distillate.
Analysis and Conclusion
    EPA recognizes that there are difficulties in the conversion of 
refinery operations from JP-4 production to gasoline production, and 
that production volumes may also be limited. EPA also recognizes that 
the burden of the conversion and compliance with the RFG and anti-
dumping requirements differs from refiner to refiner. However, as 
stated previously, EPA's authority in allowing exceptions to the 
regulations in the form of baseline adjustments is limited. 
Environmental impact and regulatory burden are the only factors EPA 
considered in determining what type of baseline adjustment, if any, 
should be allowed. EPA believes that the most appropriate measure of 
the regulatory burden in this context is the JP-4 to gasoline ratio, 
discussed above.

V. Crude Oil Quality Baseline Adjustment

A. Introduction

    Crude sulfur content is increasing nationwide.6 The ability of 
refiners to deal with this change varies. EPA is aware that the quality 
of the crude oil (with regard to sulfur content) available to refiners 
in PADD IV has been deteriorating faster than crude oil in other 
regions of the U.S. since 1990.7 In addition, refiners in this 
region do not have access to foreign crude oil imports other than those 
from Canada. Thus, the quality of crude oil available to these 
refiners, from conventional or alternative sources, is limited. Prior 
to promulgation of the December 1993 final rule, EPA was not aware that 
the deterioration of crude oil available to certain refiners (in regard 
to increasing sulfur content) might force them to cease operation since 
the burden of compliance might be prohibitively expensive.
---------------------------------------------------------------------------

    \6\ E.J. Swain, ``U.S. crude slate continues to get heavier, 
higher in sulfur,'' Oil & Gas Journal, p. 37, January 9, 1995.
    \7\ Ibid.
---------------------------------------------------------------------------

    The anti-dumping requirements contained in the December 1993 
regulations generally do not allow baseline adjustments for changing 
crude oil quality or availability. However, as discussed in the 
preamble to the December 1993 final rule, EPA recognized that a 
refiner's ability to comply with its individual baseline can be 
difficult due to changes in crude oil supplies, markets, and fuel 
specifications. As with the work-in-progress baseline adjustment (40 
CFR 80.91) and the original JP-4 baseline adjustment (40 CFR 80.91), 
EPA believes it is appropriate to provide baseline adjustments in 
situations where the anti-dumping regulatory burden is extremely 
onerous and where requiring compliance would yield little or no 
environmental benefit. Thus, EPA is finalizing such a baseline 
adjustment where a dramatic increase in crude sulfur content has 
occurred which could severely affect the anti-dumping compliance of 
refiners with extremely low baseline sulfur levels.
    EPA expects a minimal environmental impact from allowing the low-
sulfur crude baseline adjustment (based on the criteria finalized 
today) for two reasons. First, only a few refineries are expected to 
qualify for the adjustment and second, the total production volume of 
these refineries is marginal.

[[Page 9876]]

B. General Comments on the Proposal

Summary of Comments
    Several commenters felt that EPA was unjustified in granting a 
small number of refiners special treatment for what is a ``fact of 
life'' for all refiners. They felt this proposal appears to satisfy 
certain refiners at the expense of others. Some commenters claimed that 
since sour crude oil is typically less expensive than sweet crude oil, 
refiners can invest in the appropriate level of desulfurization 
capacity to refine the crude into a competitive crude slate. On the 
other hand, one commenter asserted that it is not appropriate to grant 
a waiver to purchase sour crude oil supplies, and then allow the 
production of gasoline which would not meet the anti-dumping standards.
    Other commenters opposing the proposal felt that, although it is 
very restrictive, they could not support concessions for only a few 
regulated parties. They contended that EPA should force a capital 
solution by the affected refiners, and not allow the adjustment.
Analysis and Conclusion
    In finalizing the low-sulfur crude baseline adjustment, EPA is 
using the authority granted to it by Congress to allow limited 
exceptions under narrow circumstances. As with the other baseline 
adjustments mentioned above, the appropriate criteria for obtaining an 
adjustment are designed to be stringent in order to provide relief only 
in cases of extreme burden and to maintain the environmental benefits 
of the (anti-dumping) program. EPA is not allowing adjustments for all 
refiners who have experienced increasing crude sulfur levels since 1990 
or for refiners who will experience such increases in the future. Thus, 
the existing provisions in part 40, section 80.91 of the regulations 
still apply, i.e., no adjustments for crude oil quality or availability 
changes are allowed unless the criteria finalized today are met.

C. Comments on Crude Oil Quality Changes Since 1990

    In the NPRM, EPA requested comments on inherent crude oil 
properties, other than sulfur, which have significantly deteriorated 
since 1990 and which directly and significantly affect the values of 
any fuel parameters for which an individual baseline value must be 
determined. In addition, EPA requested comments on future crude oil 
trends (i.e. whether crude sulfur content will continue to increase or 
stabilize), specifically on a regional or PADD basis.
Summary of Comments
    No commenter specified crude oil properties, other than sulfur, 
which have significantly deteriorated since 1990 and which directly and 
significantly affect the values of any fuel parameters for which an 
individual baseline value must be determined. Additionally, no 
commenter discussed future crude oil property trends. Commenters did 
discuss the RFG and anti-dumping programs, specifically with regard to 
individual baselines, as indicated below.
    One commenter in support of a baseline adjustment commented that 
the existing anti-dumping regulations have the unintended consequence 
of placing a disproportionately heavy burden on producers of clean 
gasoline which ultimately could lead to a deterioration of air quality. 
Specifically, the commenter stated that refiners who produced clean 
gasoline in 1990 are held to stricter standards than those who produced 
dirtier gasoline in 1990. Furthermore, the difficulties of the more 
stringent standards become more acute when the quality of a refiner's 
gasoline is affected by circumstances beyond the refiner's control.
    Another commenter indicated that driving the cleanest refiners out 
of business was not an intended effect of the RFG and anti-dumping 
programs, and would not promote protection of public health or the 
environment. This commenter felt the regulations should recognize the 
needs of the cleanest refiners and afford them the opportunity for 
continued operation, by allowing a low sulfur crude adjustment. The 
commenter stated that despite increased sulfur content, clean refiners 
would still produce very clean gasoline. Furthermore, the commenter 
indicated that without an appropriate and sufficient baseline 
adjustment, clean refiners may have to cease operation which could 
subsequently lead to fewer clean refineries in the petroleum industry.
    In regard to standard pipeline procedures, one commenter felt that 
certain crude oil properties were beyond the control of downstream 
refiners. Therefore, the commenter stated that refiners should be 
allowed to adjust baselines annually. As an example, the commenter 
stated that perhaps such an adjustment would be based on the naphtha 
fraction of the crude oil received from the Alaska North Slope.
Analysis and Conclusion
    EPA disagrees with the comment that refiners who produced 
relatively cleaner gasoline in 1990 are held to a stricter standard 
than those who produced relatively dirtier gasoline in 1990. The same 
basic standard applies to all refiners with an individual baseline, 
that is, they must produce gasoline as clean as the gasoline they 
produced in 1990.
    As indicated above, the original regulations generally do not allow 
baseline adjustments for changing crude oil quality or availability. 
However, during the review and approval of baselines, EPA was informed 
that the depleted supply of very sweet crude oil which had been 
processed in 1990 could force one or more refiners to cease gasoline 
production. If a refiner processed a very sweet crude (e.g., less than 
500 ppm) in 1990, its baseline sulfur level could be 50 ppm or lower. 
Because of increasing sulfur content in the crude oil supply, if that 
refiner currently processes relatively sweet crude oil (e.g., less than 
1200 ppm sulfur), it would likely be unable to comply with its 
individual baseline without severe economic burden due to its extremely 
low baseline sulfur level. It may also be extremely expensive for 
refiners to add refinery units in order to ensure compliance. For 
example, gasoline sulfur may be lowered by hydro-desulfurization of 
gasoline components and/or by charging the gasoline to blendstock 
producing units. This option is expensive and could require the 
installation of considerable new refining equipment. It could also 
require extensive volumes of hydrogen, which may be hard to produce 
within a given refinery. Thus, compliance options for such a refiner 
might be prohibitively expensive.
    In response to the comment on standard pipeline procedures, the 
purpose of the low-sulfur crude baseline adjustment is to provide 
refiners limited relief in situations where the anti-dumping regulatory 
burden is extremely onerous and where requiring compliance would yield 
little or no environmental benefit. Although a few refiners will be 
granted the low-sulfur crude baseline adjustment, these refiners must 
realize that they (like all other refiners) will be responsible for 
future adaptations to changing crude sulfur levels. Baseline 
adjustments are intended to reduce, not eliminate, the burden 
associated with regulatory compliance. If the burden were completely 
eliminated, then the required criteria would no longer be met and the 
goals of the anti-dumping program would no longer be fulfilled.

D. Comments on the Proposed Criteria for a Baseline Adjustment

    In the NPRM, EPA proposed seven criteria that a refiner would have 
to meet to qualify for the low-sulfur crude baseline adjustment. 
Comments on these criteria are discussed below.

Criterion 1: The refinery produces no reformulated gasoline.

    The anti-dumping requirements, in general, apply to all 
conventional gasoline whether or not RFG is produced. Under this 
adjustment, however, no dumping will result from RFG production. If a 
refiner who receives this baseline adjustment subsequently produces 
RFG, the refiner's conventional gasoline compliance will be subject to 
its original unadjusted baseline during the current averaging period 
and in all subsequent years. However, in the NPRM, EPA also proposed 
that the eligibility of any refinery of a multi-refinery company for 
this baseline adjustment is not dependent on the RFG production of the 
refining company's other refineries.
Summary of Comments
    Some commenters stated that if a baseline adjustment were made, the 
prohibition of RFG production would be unnecessary and overly 
restrictive. Commenters added that restrictions on baseline adjustment 
qualification may limit a refiner's ability to adapt to future, 
unforeseen market changes. Commenters stated that this restriction 
would have an adverse impact on cleaner operations by limiting 
flexibility and competition, and could lead to a future shortage of 
RFG. It was pointed out that many refiners would be prevented from 
producing RFG if they were forced to revert back to their unadjusted 
baselines. Commenters argued that, if refiners were forced to choose 
between RFG and conventional fuel production based on artificial 
factors rather than a response to market demand, refiners with higher 
sulfur baselines would be able to compete in both markets 
simultaneously with less competition. Therefore, the commenters 
suggested that EPA should allow the baseline adjustment for refiners 
that meet the other proposed criteria, regardless of their RFG 
production.
Analysis and Conclusion
    EPA considered the above comments in its decision, but maintains 
that a refiner must not produce RFG to qualify for a baseline 
adjustment. EPA believes that refiners who were able to adjust refinery 
operations (through capital investment or process modifications) to 
produce RFG should be able to accommodate increases in crude sulfur 
content. In addition, the Agency believes that prohibiting RFG 
production is the best way to ensure that ``no dumping'' will occur. 
EPA does not believe that this requirement is unduly restrictive. 
Therefore, EPA is finalizing the proposed criterion that a refiner must 
not produce RFG to qualify for this baseline adjustment.

Criterion 2: A refiner has an unadjusted baseline sulfur value less 
than or equal to 50 ppm.

    EPA believes that requiring a threshold sulfur content of 50 ppm is 
appropriate because higher baseline levels would indicate that the 
refiner's 1990 crude slate was not extremely low in sulfur. In 
addition, a refiner with a higher baseline sulfur level should have 
sufficient leeway, e.g., types of crude oil supplies used or available 
and processing flexibility, to comply with its individual baseline. In 
the NPRM, EPA requested comments on the appropriateness of requiring a 
threshold sulfur content, and on the suitability of 50 ppm or another 
concentration as a threshold level.
Summary of Comments
    Most commenters opposing the baseline adjustment were concerned 
that such an adjustment would not result in equal treatment for all, 
and would give some refiners an unfair advantage. These commenters 
contended that the rule should not be applied to only those with sulfur 
levels below 50 ppm or any other number, because increased crude sulfur 
impacts every refiner regardless of its baseline. Commenters added that 
all refiners are faced with changing crude oil quality; refiners must 
consider these changes when planning future capital investments and 
product slates. Furthermore, many commenters asserted that there is no 
basis for the 50 ppm threshold proposed by EPA. They indicated that 
this level should be significantly raised or eliminated. In addition, 
one commenter argued that requests for adjustment could go beyond crude 
sulfur content, though the commenter did not specify which other crude 
oil parameters could be investigated. Finally, commenters contended 
that this rule could be challenged based on the competitive advantage 
gained by exempt parties.
Analysis and Conclusion
    As with any baseline adjustment, EPA's authority to allow 
adjustments is limited. As stated previously, exceptions to this 
requirement of the Act will only be allowed for cases of extreme 
economic burden with minimal environmental impact. Not all refiners who 
have experienced increases in crude oil sulfur levels are unduly 
burdened. In order to quantify this burden, and for the reasons stated 
earlier, EPA proposed a 50 ppm threshold value for the crude oil sulfur 
content of a refiner's unadjusted baseline. Because commenters did not 
suggest another threshold value and EPA is not aware of another value 
that would be more appropriate, the Agency is finalizing an unadjusted 
baseline sulfur level of 50 ppm. Refiners must comply with this sulfur 
criterion to qualify for a low-sulfur crude baseline adjustment.

Criterion 3: The affected refinery of a multi-refinery refiner may not 
be aggregated with the refiner's other refineries for compliance 
purposes.

    EPA proposed that this baseline adjustment would be available to 
refineries of both single-refinery and multi-refinery companies. 
However, EPA also proposed that the affected refinery of a multi-
refinery refining company may not be aggregated with the company's 
other refineries for compliance purposes. If a refinery that is granted 
a low-sulfur crude baseline adjustment is subsequently included in an 
aggregate baseline, its conventional gasoline compliance will be 
subject to its original unadjusted baseline during the current 
averaging period and in all subsequent years. Therefore, to qualify for 
a low-sulfur crude baseline adjustment, the affected refinery of a 
multi-refinery company may not be aggregated with the refining 
company's other refineries for compliance purposes.
Summary of Comments
    Commenters opposing the baseline adjustment proposal suggested that 
EPA should not tie eligibility for the adjustment to aggregation. If 
there is a need for adjustment, it should affect the refinery only, 
without the need to revert back to the unadjusted baseline.
Analysis and Conclusion
    EPA agrees that allowing refiners to comply with the anti-dumping 
requirements on an aggregate basis provides flexibility. However, the 
Agency still believes that refiners should not be able to aggregate and 
also receive a low-sulfur crude baseline adjustment for one of its 
refineries. Because the ability to aggregate is limited to multi-
refinery refiners, such refiners have more flexibility than single 
refiners in regard to baseline compliance. Thus, they already have

[[Page 9878]]

some means of reducing the effect of increasing crude sulfur on their 
compliance. EPA believes it would be inappropriate, and possibly anti-
competitive, to allow a refinery receiving this baseline adjustment to 
also be included in an aggregate baseline.

Criterion 4: The installation of the refinery units necessary to 
process higher sulfur crude oil supplies to comply with the refinery's 
actual (i.e., unadjusted) baseline would cost $10 million or be greater 
than or equal to 10 percent of the depreciated book value of the 
refinery as of January 1, 1995.

    The purpose of this provision is to ensure that baseline 
adjustments are limited to cases of extreme burden or economic 
hardship. (This is the same requirement for economic burden that must 
be met by a refiner seeking a work-in-progress baseline adjustment.) 
EPA requested comments on this criterion and whether the specified 
values of $10 million or 10 percent are adequate given the type of unit 
(e.g., hydrotreater) that a refiner would have to install in order to 
comply. EPA also requested comments on (1) the economic burden, if any, 
of producing and selling gasoline blendstocks in lieu of finished 
gasoline, and (2) the economic burden of complying with an unadjusted 
baseline under the circumstances described above by modifying refinery 
operations in ways other than installing major refinery units.
Summary of Comments
    Most commenters supported the proposed criterion of $10 million or 
10 percent and stated that this criterion is fair and appropriate. One 
commenter stated that refining equipment is expensive and it is not 
difficult for a refiner to spend $10 million. Furthermore, the 
commenter indicated that the 10 percent depreciation value was not a 
significant hurdle either.
    Commenters also expressed concern that if this adjustment were not 
allowed, refiners would be forced by the regulation to produce 
blendstocks in lieu of gasoline. They stated that the discounts 
refiners would be forced to give for at least some of those blendstocks 
would be too great to remain viable; refiners could not profitably 
produce blendstocks in lieu of gasoline. The commenters contended that 
the decision to produce gasoline is dictated by refinery design and 
marketing. One commenter added that restricting the ability to freely 
choose the most profitable product mix would be an economic 
disadvantage.
    In response to the second request, nearly all commenters agreed 
that increases in crude sulfur directly (but not linearly) lead to 
increases in gasoline sulfur, unless major structural and operational 
modifications are made to the refinery (assuming the necessary 
equipment is not already in place.) Whether and how EPA should address 
this situation, though, is a point of contention.
    One commenter, however, stated that changes in crude sulfur are a 
poor indicator of gasoline sulfur levels. This commenter suggested that 
it would be more appropriate to consider catalytic cracking unit 
(catcracker) feed sulfur. This suggestion applies to refineries without 
vacuum units, which catcrack reduced crude. Catcracker sulfur can only 
be reduced by either lowering the distillation end point or 
hydrotreating the feed or the blendstock. The commenter also stated, 
though, that lowering the end point artificially forces a refiner to 
operate at less than optimum conditions. Furthermore, hydrotreating the 
blendstock stream is impractical since it reduces the octane value of 
the blendstock and forces higher reformer severity. The commenter added 
that feed stream hydrotreatment is expensive.
Analysis and Conclusion
    EPA agrees that a refiner could be subject to an extreme economic 
burden if it were forced to produce blendstocks in lieu of gasoline or 
to significantly modify refinery operations in order to comply with the 
anti-dumping regulations (although some refiners may produce 
blendstocks or modify operations at a high cost for other reasons). As 
a result, EPA believes that limited relief from these potential burdens 
is necessary and can be provided through a low-sulfur crude baseline 
adjustment which the Agency is finalizing today.
    EPA agrees that it may not be difficult for a refiner who meets the 
other criteria specified for this baseline adjustment to spend $10 
million to reduce sulfur in order to comply with the anti-dumping 
requirements. Nonetheless, EPA believes this economic criteria is 
essential for showing extreme economic burden, and thus is retaining 
this provision as proposed.
    EPA generally agrees with the comment that changes in crude sulfur 
are a poor indicator of gasoline sulfur levels. However, given the 
other criteria that a refiner must meet to obtain this baseline 
adjustment, particularly the low threshold values for baseline gasoline 
sulfur and crude sulfur changes, EPA believes that it is appropriate to 
consider the influence of extremely low crude sulfur levels on 
extremely low baseline sulfur levels. As will be discussed below, EPA 
is not basing the actual adjustment on the relationship between crude 
sulfur and baseline sulfur levels.

Criterion 5: The refiner has access to a geographically-limited crude 
oil supply.

    EPA proposed that a refiner must show that it could not reasonably 
or economically obtain crude oil from an alternative source that could 
be refined into conventional gasoline in compliance with the refiner's 
unadjusted baseline. EPA requested comment on this proposed provision 
and on criteria that should be used to evaluate ``reasonably and 
economically available''.
Summary of Comments
    Small refiners with restricted operational flexibility and limited 
financial access supported the proposal. They felt that without more 
than the 125 percent flexibility given in the original regulation 
(i.e., simple model anti-dumping compliance for sulfur), crude sulfur 
increases would force very clean small refiners with low baselines out 
of business. One commenter stated that refiners in the Rocky Mountains 
have traditionally relied on very sweet crude oil supplies which have 
historically been available in the area. However, the sulfur content of 
Rocky Mountain crude oil has increased at a greater rate than that of 
crude oil in the rest of the country. This commenter stated that these 
refiners realistically only have access, due to geography and 
economics, to crude oil supplies imported at the Canadian border.
    One commenter suggested that EPA should provide examples of 
refiners meeting this requirement (e.g., all single-refinery refiners 
in land-locked states). This commenter also suggested additional 
criteria EPA could consider in allowing this adjustment, such as the 
distance from a particular refinery to alternative sources of low 
sulfur crude supplies, the size of the refinery, the ability of the 
refiner to access and transport such crude oil supplies, and the extent 
to which the viability of the refiner is threatened by the cost of 
obtaining alternative crude oil supplies. Another criterion that was 
suggested would be the increase in the average sulfur content of the 
crude slate used for gasoline production between 1990 and 1994.
Analysis and Conclusion
    Although EPA agrees with the importance of evaluating the

[[Page 9879]]

information described in the above suggestion, it does not believe it 
is necessary to impose additional specific criteria for determining who 
should qualify for a low-sulfur crude baseline adjustment. EPA will 
consider these factors in determining whether a refinery meets this 
criterion and will evaluate petitions for this low-sulfur crude 
baseline adjustment on a case-by case basis. EPA is finalizing this 
provision as proposed.

Criterion 6: The refiner has experienced an average crude sulfur 
increase greater than or equal to 25 percent since 1990.

    EPA proposed that the highest annual-average crude sulfur slate 
used during the period 1991-1994, inclusive, be compared to the 1990 
sulfur level to determine if the ``25 percent'' criterion is met. 
Comments were requested concerning the level of difference between 1990 
and post-1990 crude sulfur contents that should exist in order to 
obtain an adjustment, and whether 1991-1994 is an appropriate 
comparison period or whether some other comparison should be 
established. The Agency also requested comments as to whether it would 
be appropriate, and feasible, to distinguish crude oil supplies used 
solely for gasoline production from crude oil supplies used to produce 
other refinery products. If such distinction were possible, EPA 
believes it would be appropriate to base all calculations (pertaining 
to this adjustment) only on the volumes of each crude used to produce 
gasoline.
Summary of Comments
    Opponents to the proposal were concerned that this adjustment 
rewards refiners that purchased higher sulfur crude oil supplies after 
1990. They indicated that the trend toward sour crude oil supplies was 
recognized during the Regulatory Negotiation, and that the annual 
averaging and 125 percent compliance provisions for conventional 
gasoline were created to address the situation. These commenters felt 
that if the 125 percent compliance level is not sufficient, it should 
be changed for all parties.
    Some commenters supporting this baseline adjustment indicated that 
it is feasible to distinguish crude oil supplies used solely for 
gasoline production from crude oil supplies used to produce other 
refinery products, and that it would be appropriate to evaluate this 
criterion based only on the crude used for gasoline production.
Analysis and Conclusion
    Although the trend toward sour crude oil supplies was recognized in 
the Regulatory Negotiation, the quality of the crude oil available to 
refiners in PADD IV has been deteriorating faster than the rest of the 
U.S. since 1990. As a result, some refiners with very clean baselines 
have found it very difficult to comply with the anti-dumping 
regulations. EPA is finalizing the low-sulfur crude baseline adjustment 
for those refiners who qualify for the adjustment based on the criteria 
finalized today. However, EPA believes that the criteria are 
necessarily stringent so that only those refiners who are extremely 
burdened will qualify. In addition, EPA believes that because the 
program is so restrictive, the environmental impact of the adjustment 
will be minimal and will not negate the benefits of the anti-dumping 
program.
    Commenters supported EPA's belief (as stated in the NPRM) that it 
is appropriate and feasible to base the low-sulfur crude baseline 
adjustment only on crude used for gasoline production. EPA is 
finalizing this criterion as proposed, with a correction to the 
regulations (contained in the proposal) which reflects the Agency's 
intent in both the proposal and today's final rule, as follows. In the 
proposed regulations, one aspect of the equation associated with this 
criterion was incorrectly defined, namely, the definition of the 
variable ``CSHI''. In the proposed regulations, ``CSHI'' was defined as 
the ``highest annual average crude slate per paragraph (e)(8)(ii)(B) of 
this section.'' Paragraph (e)(8)(ii)(B) of that section referenced the 
``* * * highest crude sulfur level (ppm) of the crude slate utilized in 
the production of gasoline in the refinery in 1994 * * *.'' Thus, the 
definition of ``CSHI'' in the proposed regulations was not consistent 
with the discussion contained in the proposal preamble (60 FR 40012. 
August 4, 1995) which referenced the years 1991-1994, as does today's 
regulation. Today's regulation corrects this error to reflect the 
Agency's intent in both the NPRM and today's final rulemaking 
preambles.

Criterion 7: Gasoline sulfur changes are directly and solely 
attributable to the crude sulfur change, and not due to alterations in 
refinery operation nor choice of products.

    No comments were received on this proposed criterion. EPA is thus 
finalizing this requirement.

E. Comments on the Proposed Options for a Baseline Adjustment

    EPA requested comments on the options proposed for determining the 
adjusted baseline sulfur level if a refiner meets the proposed criteria 
and is approved for a baseline adjustment. These options are summarized 
below. EPA also requested comments on its view that a refiner should 
not be exempt from its other anti-dumping compliance baselines, i.e., 
all other simple model requirements as well as exhaust benzene and 
exhaust toxics emissions under the complex model since those emissions 
are minimally affected by sulfur. See the support document for this 
rule for more discussion related to the various proposed options. 
(``Regulation of Fuels and Fuel Additives: Standards for Reformulated 
and Conventional Gasoline--Detailed Discussion and Analysis'', Air 
Docket A-95-03.)
    Option 1: EPA proposed that the adjusted baseline sulfur value be 
related to the ratio of the sulfur content of the highest sulfur crude 
utilized in 1994 to the average sulfur content of the crude slate 
utilized in 1990. Under this option, if a refiner used two crude oil 
supplies in its gasoline production in 1994 with sulfur levels of 1000 
ppm and 2100 ppm, the higher sulfur crude would be used in the 
determination of the adjusted baseline sulfur value. If, for example, 
the 1990 average crude sulfur content was 500 ppm (resulting in a 
baseline sulfur value of approximately 20 ppm), the adjusted baseline 
sulfur value would be 84 ppm {20 ppm  x  (2100/500)}. EPA specifically 
requested comments on whether the highest sulfur crude from 1991-1994 
should be used rather than just considering 1994.
    Option 2: EPA proposed that the adjusted baseline sulfur value be 
related to the ratio of the highest average sulfur content of the crude 
slate used in 1991, 1992, 1993 or 1994 to the average sulfur content of 
the crude slate used in 1990. Incorporating the 1990 baseline and crude 
sulfur levels from Option 1, and average crude sulfur contents of 1000, 
1100, 1400, and 1300 ppm for years 1991, 1992, 1993 and 1994, 
respectively, the adjusted baseline sulfur value would be 56 ppm, i.e., 
20 ppm x (1400/500).
    Option 3: EPA proposed that an adjusted baseline sulfur value be 
determined for each year through 1999. Beginning January 1, 2000, the 
adjusted baseline sulfur value would be the same as it was in 1999. EPA 
proposed that the annual adjusted value be determined over the four 
years prior to the year before the new value takes effect, except for 
1995 and 1996 which would be determined as specified in Option 1 above 
(and for which the adjusted baseline sulfur value would be the same). 
EPA also proposed that if less than a 25 percent difference occurs 
between the 1990 average crude sulfur level and the average crude 
sulfur level over a four-year period, the refiner would receive no 
additional

[[Page 9880]]

adjustments, and its most recent adjusted baseline sulfur value would 
become its permanent baseline sulfur value at that point. For example, 
the standard for 1997 would be based on the ratio of the average sulfur 
content of the crude oil used in 1992, 1993, 1994 or 1995 to the 
average sulfur content of the crude slate used in 1990. EPA proposed 
that the resulting adjusted baseline sulfur value be submitted to the 
Agency for evaluation and approval by June 1 of the year preceding the 
year for which it would be the standard. In the example given, the 
adjusted baseline value (and all supporting information) would have to 
be submitted by June 1, 1996.
    Option 4: For this option, EPA proposed requirements similar to 
those presented for Option 3 except that adjustments would only be 
allowed through 1997, i.e., the simple model years. Beginning in 1998, 
the adjusted baseline sulfur value would be equal to the value in 1997.
    Option 5: EPA proposed that the adjusted baseline sulfur value be 
the unadjusted baseline sulfur value plus 50 ppm. EPA specifically 
solicited comments on the appropriateness of using 100 ppm or 150 ppm 
instead of 50 ppm.
    In order to show that increasing gasoline sulfur is due solely to 
increasing crude sulfur, EPA also requested comments as to whether 
changes in refinery configuration or refinery operation should be 
prohibited.
Summary of Comments
    Commenters suggested that if a one-time baseline adjustment is 
granted, refiners should be given the opportunity to estimate the 
compliance burden over a five to ten year period. According to 
commenters this concession would accommodate someone who meets the 
requirements in the short term, but who would require more substantial 
investment to implement a long term solution. Another commenter felt a 
one-time adjustment would only benefit the refiner if it were large 
enough to provide relief for the foreseeable future. Commenters 
indicated that the EPA proposals did not provide adequate time for 
adjustment. Furthermore, one commenter argued that proposing a one-time 
adjustment for a dynamic situation (changing crude oil sulfur) is 
illogical. The commenter explained that other adjustments allowed by 
the regulation, such as the work-in-progress, were for temporary 
events.
    Of the options presented in the NPRM, most commenters who supported 
any adjustment felt that Option 1 was too restrictive and would offer 
little relief. They preferred Option 5 as the simplest and most 
flexible approach. One commenter stated that Options 1 and 2 were 
inappropriate since they include the assumption that crude sulfur and 
gasoline sulfur increase at a constant ratio, which is not correct. The 
commenter added that the sulfur content of gasoline depends on several 
factors such as the crude oil composition, refinery operation, and the 
type of gasoline produced. This commenter contended that Options 3 and 
4 were also inappropriate, although Option 3 was preferable to Option 4 
because of the additional time provided for obtaining a final 
adjustment. This commenter supported continuing relief, but did not 
support a limit beginning in 1997 or 1999. The commenter considered 
Option 5 to be the most appropriate option for making a sulfur 
adjustment, if the added amount was 150 ppm. This commenter also 
expressed concern regarding the low repeatability of tests for sulfur 
below 100 ppm. The commenter claimed that EPA appears to recognize the 
low repeatability by defining a negligible quantity limit of 30 ppm. 
Finally, this commenter proposed that EPA provide another opportunity 
for adjustment in five years, if crude sulfur levels continue to 
increase at faster rates than anticipated.
    One commenter felt that if a refiner does not produce RFG, does not 
aggregate, has a limited crude supply, and meets the ``financial 
hurdles'', there is no need for arbitrary numbers, and such refiners 
should be given the statutory baseline of 338 ppm.
    In addition to these concerns, other commenters opposed the 
continuation of the adjustment beyond the simple model time frame. They 
stated the complex model provides enough flexibility for refiners, and 
that EPA has neither the expertise to evaluate non-sulfur control 
options for complying with NOX requirements nor the ability to 
shift from the simple model to the complex model for exhaust benzene. 
Commenters also stated that the simple model sulfur cap can be avoided 
by using the complex model. One commenter suggested that if EPA feels 
that more flexibility is needed, it could allow separate use of the 
simple and complex models for conventional fuel and RFG sulfur, 
olefins, and T90. This approach would provide industry-wide flexibility 
and would minimize the need to provide special relief to a limited 
number of refiners.
    EPA also received a suggested option from a commenter who proposed 
that a refiner should be able to produce conventional gasoline which 
does not meet, on average, the requirements of its individual baseline 
if the refiner could show that deviation from its baseline was directly 
and solely attributable to crude sulfur change, and not due to 
alterations in refinery operation or choice of products. The suggested 
option also contained other requirements, which are essentially those 
finalized today by EPA, that are necessary for determining baseline 
adjustment eligibility.
Analysis and Conclusion
    All five proposed options would determine the adjusted baseline 
sulfur value prior to the period of production, thus treating an 
affected refiner like all other refiners. Although today's rule 
provides some relief for refiners who are unduly burdened by baseline 
compliance, these refiners may have to modify refinery operations in 
the future to accommodate increasing crude sulfur levels. In the 
future, however, refinery modifications will likely be required of most 
refiners, without the benefit of a baseline adjustment.
    After careful analysis of the proposed options, sulfur distribution 
data, and comments, EPA is finalizing essentially Option 5 in today's 
rule. Under this option, a refiner's one-time adjusted baseline sulfur 
value will be equal to the refiners unadjusted baseline sulfur value 
plus 100 ppm. EPA believes that a 100 ppm sulfur adjustment is 
appropriate for the following reasons. First, 50 ppm, as suggested in 
the NPRM, is too low. Upon further consideration, especially regarding 
the criteria which must be met in order to obtain this adjustment, EPA 
believes that a sulfur adjustment of 50 ppm would not provide 
sufficient relief. Refiners who are severely burdened by the anti-
dumping regulations, and who meet the criteria, will likely need more 
than a 50 ppm baseline adjustment in order to reduce the extreme burden 
of the regulations. Second, a baseline adjustment value of 150 ppm 
sulfur is too high. Although this value was proposed in the NPRM, the 
Agency believes that an adjustment of this magnitude would negate the 
intentions of this regulation (which is to provide reasonable relief 
for extremely burdened refiners) and the goals of the anti-dumping 
program. If an adjustment of 150 ppm sulfur was permitted, several 
refiners not qualifying for the adjustment (due to the 50 ppm threshold 
required in Criterion 2) would have lower baseline sulfur values than 
some refiners who do qualify for the adjustment. Finally, EPA believes 
that a sulfur adjustment of 100 ppm will provide adequate relief for 
qualifying refiners while maintaining the

[[Page 9881]]

environmental benefits of the anti-dumping program.
    Based on the above decision, 150 ppm is the maximum adjusted 
baseline sulfur value that a refiner could be granted under today's 
final rule (50 ppm threshold + 100 ppm additional sulfur = 150 ppm 
maximum adjusted baseline value for sulfur). The Agency believes that 
this option will provide refiners maximum flexibility with minimal 
anti-competitive effects.
    Regarding the comment that EPA should provide another opportunity 
for adjustment in five years if crude sulfur levels continue to 
increase at faster rates than expected, EPA believes this action would 
be inappropriate. Baseline adjustments are intended to provide relief 
where the burden is extreme. EPA expects that the refining industry 
will develop means of dealing with increasing crude sulfur levels. The 
cost of such means may be high, but given the lead time, and the 
industry's knowledge of crude oil exploration and production, it is 
unlikely that a well-prepared refiner would be extremely burdened by 
future high sulfur levels.
    As with other baseline adjustments, refiners receiving this 
baseline adjustment will retain the adjustment even after the Simple 
Model years, i.e., after 1997. Although the Complex Model does provide 
more compliance flexibility than the Simple Model, EPA, via the 
baseline adjustments, is providing relief for compliance with anti-
dumping requirements as a whole, and not just the Simple or Complex 
Model requirements. In some cases, even the Complex Model does not 
provide enough flexibility such that an extreme burden (when evaluated 
under the Simple Model) is reduced. EPA also disagrees with commenters 
who suggested that EPA allow compliance to be determined under one 
model for conventional gasoline and under the other model for RFG. The 
reasons for requiring the use of the same models for both conventional 
and RFG were discussed at length in the December 1993 final rule. 
Additionally, as stated several times previously, EPA does not have 
authority and does not believe it is appropriate to provide a broad, 
i.e., industry-wide, adjustment program.
    EPA considered the suggested option, but is not finalizing it due 
to some concerns about the concept and detail of the option. This 
option would exempt a qualifying refiner from complying with its anti-
dumping compliance baseline if the refiner can show, at the end of the 
compliance period, that deviation from its baseline was directly and 
solely attributable to crude sulfur change. Thus, unlike all other 
refiners, a qualifying refiner would have no clearly defined standard 
prior to year of production. Furthermore, if EPA was not satisfied that 
deviation from its baseline was directly and solely attributable to 
crude sulfur change, the refiner would have to determine compliance 
relative to its unadjusted baseline and would likely be out of 
compliance.

VI. Low Sulfur, Low Olefin Baseline Adjustment

A. Introduction

    Certain very clean individual baselines, i.e., those with extremely 
low values for one or more fuel parameters, can make compliance for 
refiners extremely difficult or impossible due to (1) limited 
maneuverability about the clean baseline and (2) limited flexibility 
with regard to annual averaging. During the review and approval of 
individual baselines, EPA was informed that extremely low baseline 
sulfur and olefin values could force a refiner to cease gasoline 
production. In addition, refiners with very clean baselines presumably 
produce the least polluting gasoline. It would be environmentally 
harmful if these refiners ceased production and their volumes were then 
produced by refiners with relatively dirtier baselines.
    EPA believes it is appropriate to provide limited relief in the 
form of a baseline adjustment in those few cases where the regulatory 
burden is extremely onerous and where requiring compliance would yield 
little or no environmental benefit.

B. General Comments on the Proposal

    To provide some relief for those refiners who are severely burdened 
by the combination of extremely low sulfur and olefin levels, EPA 
proposed a baseline adjustment which set the annual average sulfur and 
olefin values to 30 ppm and 1.0 volume percent (vol%), respectively. To 
receive this adjustment, EPA proposed that a refiner must meet the 
following criteria:
    (1) Have an individual baseline sulfur level less than or equal to 
30 ppm and an individual olefin level less than or equal to 1.0 vol%;
    (2) Show that installation of the refinery units necessary for 
compliance with an unadjusted baseline would cost $10 million or be at 
least 10 percent of the depreciated book value of the refinery as of 
January 1, 1995.
    Additionally, EPA proposed that such an adjustment would be 
available to both single-refinery and multi-refinery refining 
companies. However, the affected refinery of a multi-refinery company 
would not be allowed to be aggregated with the company's other 
refineries for compliance purposes. If at any time a given refinery's 
baseline is aggregated with another refinery's baseline for compliance 
purposes, EPA proposed that the applicable individual baselines will 
revert to the unadjusted baselines.
    EPA also proposed that the summer and winter individual baseline 
values for sulfur and olefins be set to 30 ppm and 1.0 vol%, 
respectively.
Summary and Analysis of Comments
    Several commenters supported this proposed adjustment and EPA's 
statement that no environmental impacts would occur due to this rule. 
Additionally, many commenters cited problems with the accuracy of 
laboratory test methods at very low sulfur and olefin levels as further 
justification for this baseline adjustment. Commenters stated that 
errors in lab analysis, sample contamination, or product commingling 
can incorrectly result in fuel parameter values which are greater than 
the baseline values when those baseline values are extremely low. EPA 
agrees that this baseline adjustment will provide flexibility for 
qualifying refiners and will reduce the complications associated with 
testing low sulfur and olefin levels.
    While the majority of commenters supported this proposal, many of 
them suggested changes in the criteria for the adjustment. One 
commenter suggested that EPA remove the aggregation requirement. This 
commenter stated that a conflict arises when a refiner also qualifies 
for a JP-4 baseline adjustment (under the JP-4 baseline adjustments, in 
certain instances, a qualifying multi-refinery refiner must determine 
its anti-dumping compliance on an aggregate basis). EPA agrees with 
this comment. EPA proposed the aggregation requirement because it 
believed that, as for certain other baseline adjustments, it would be 
inappropriate to provide a baseline adjustment and to also allow a 
refinery receiving such an adjustment to be included in an aggregate 
baseline for compliance purposes. Refiners who can comply with the 
reformulated and anti-dumping regulations on an aggregate basis (i.e., 
multi-refinery refiners) already have a degree of flexibility over 
single-refinery refiners, and EPA believed that allowing a refinery 
both a baseline adjustment and the ability to be included in an 
aggregate baseline might provide a competitive advantage to certain 
refiners. However, EPA did not intend that one baseline adjustment 
would eliminate use of another baseline

[[Page 9882]]

adjustment, and believes that this particular adjustment (because of 
the extremely low sulfur and olefin levels involved), when coupled with 
the ability to aggregate, would not create a significant competitive 
advantage. Thus, EPA is not finalizing the requirement that refiners 
who receive this low sulfur/low olefin adjustment must revert to the 
unadjusted baseline if that refinery is included in an aggregate 
baseline.
    Several commenters suggested removing the economic criterion. 
Commenters stated that requiring large capital expenditures as a 
condition for this adjustment is unfair and devalues the investment in 
all such refineries. Commenters felt that refinery modifications would 
not guarantee compliance with an ultra-clean baseline. Commenters 
stated that even the allowed 125 percent of such ultra-low values could 
be less than the reproducibility and could approach the lower limit of 
the test method. Additionally, commenters said that subtle changes in 
the crude slate could affect compliance for these refiners.
    EPA agrees that for extremely low sulfur or olefin values, it may 
be almost impossible to install additional equipment or take other 
actions to ensure compliance with 100 percent or even 125 percent of 
the baseline values. In such cases, the burden would most likely exceed 
$10 million or 10 percent of the depreciated refinery value as proposed 
in the NPRM. To require demonstration of this would be of little 
additional value. Thus, EPA is not finalizing that provision of this 
baseline adjustment.
    EPA proposed two options for assigning seasonal adjusted sulfur and 
olefins values for summer and winter. The first option was to set these 
values to 30 ppm and 1.0 vol%, respectively, as for the annual average 
values. The other option was to use the refiner's own ratio of summer 
and winter values to determine the seasonal values. Few commenters 
indicated a preference for assigning seasonal baseline sulfur and 
olefin levels. EPA is thus promulgating its first option, that is, 
values of 30 ppm sulfur and 1.0 vol% olefins for both the annual 
average and seasonal values. EPA believes this choice is appropriate 
since, under this rule, baseline values for these two fuel parameters 
are different from the actual unadjusted baseline values of qualifying 
refiners. Additionally, based on comments mentioned earlier, testing of 
extremely low sulfur and low olefin values could have resulted in 
inaccurate unadjusted baseline values. Thus any ratio calculated from 
those values would also be inaccurate.
    One commenter felt that refiners should be allowed to use the 30 
ppm sulfur and 1.0 vol% olefin levels as threshold values which would 
also curtail testing of these trace parameters. This rule is only 
concerned with baseline development, for which all testing has been 
completed, and does not address compliance issues.

C. Provisions of the Final Rule

    To obtain this baseline adjustment, a refinery must have a baseline 
sulfur value less than or equal to 30 ppm and a baseline olefin value 
less than or equal to 1.0 vol%. A refinery that meets this criteria 
will have an adjusted baseline sulfur value of 30 ppm and an adjusted 
baseline olefin value of 1.0 vol% as its summer, winter and annual 
average values. Although for most baseline adjustments refiners are 
required to petition EPA for the adjustment, in this case, since 
baselines are already established, it is more efficient for EPA to 
determine which refineries qualify for this baseline adjustment, rather 
than require such refineries to petition EPA. Thus, refiners with 
refineries that qualify for this adjustment will receive notification 
from EPA in a timely manner.

VII. Environmental and Economic Impacts

    EPA expects a negligible environmental impact from allowing 
baseline adjustments under the criteria of this rule because (1) only a 
few refiners are expected to qualify for the adjustments (about 16), 
and (2) the total gasoline production of the qualifying refiners is 
small (less than three percent of annual gasoline production).
    To quantitatively illustrate this negligible impact, EPA used the 
Complex Model (an emissions model that indicates changes in in-use 
motor vehicle emissions based on changes in one or more of the gasoline 
fuel parameters evaluated by the model) to determine the adjustments' 
effects on harmful exhaust toxics and NOX emissions. Results from 
the model indicate less than a one percent increase in exhaust toxics 
emissions due to these three baseline adjustments (primarily due to the 
JP-4 adjustment), and less than a 0.1 percent increase in NOX 
emissions (primarily due to the low sulfur crude and low sulfur/low 
olefins adjustments). The low sulfur crude and low sulfur/low olefins 
baseline adjustments have almost no impact on exhaust toxics emissions, 
and the JP-4 baseline adjustment will likely yield a decrease in annual 
NOX emissions. Refineries affected by this rule are geographically 
dispersed throughout the United States, mostly in ozone attainment 
areas.
    The economic impacts of this rule are generally beneficial to 
affected refiners due to the additional flexibility provided by this 
action. Minimal anti-competitive effects are expected.
    A more comprehensive description of the environmental and economic 
impacts of the RFG program is described in the Regulatory Impact 
Analysis (RIA) supporting the December 1993 rule. This RIA is available 
in Public Docket A-92-12 located at Room M-1500, Waterside Mall (ground 
floor), U.S. Environmental Protection Agency, 401 M Street S.W., 
Washington, D.C. 20460.

VIII. Administrative Requirements

A. Administrative Designation

    Pursuant to Executive Order 12866, (58 FR 51735, October 4, 1993) 
the Agency must determine whether this regulatory action is 
``significant'' and therefore subject to OMB review and the 
requirements of the Executive Order. The 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, it has been 
determined that this FRM is not a ``significant regulatory action.''

B. Impact on Small Entities

    EPA has determined that this rule will not have a significant 
economic impact on a substantial number of small entities, and that it 
is therefore not necessary to prepare a regulatory flexibility analysis 
in conjunction with this final rule. Because today's rule provides for 
less stringent requirements than the December 1993 regulations for 
qualifying refiners, small entities which qualify for one or more of 
the baseline adjustments contained herein will find

[[Page 9883]]

it easier to comply with the requirements of the RFG and anti-dumping 
programs.

C. Paperwork Reduction Act

    The Paperwork Reduction Act of 1980, 44 U.S.C. 3501 et seq., and 
implementing regulations, 5 CFR Part 1320, do not apply to this action 
as it does not involve the collection of information as defined 
therein.

D. Unfunded Mandates Act

    Under section 202 of the Unfunded Mandates Reform Act of 1995 
(``Unfunded Mandates Act''), 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 
expenditure by State, local, and tribal governments, in the aggregate; 
or by the 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.
    EPA has determined that today's action does not include a Federal 
mandate that may result in estimated costs of $100 million or more to 
either State, local or tribal governments in the aggregate, or to the 
private sector. This action has the net effect of reducing burden of 
the RFG program on regulated entities. Therefore, the requirements of 
the Unfunded Mandates Act do not apply to this action.

E. Submission to Congress and the General Accounting Office

    Under 5 U.S.C. 801(a)(1)(A) as added by the Small Business 
Regulatory Enforcement Fairness Act of 1996, EPA submitted 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 
General Accounting Office prior to publication of the rule in today's 
Federal Register. This rule is not a ``major rule'' as defined by 5 
U.S.C. 804(2).

IX. Statutory Authority

    The statutory authority for the action promulgated today is granted 
to EPA by sections 211 (c) and (k) and 301 of the Clean Air Act, as 
amended; 42 U.S.C. 7545 (c) and (k), and 7601.

    1. The authority citation for part 80 continues to read as follows:

    Authority: Sections 114, 211 and 301 of the Clean Air Act as 
amended (42 U.S.C. 7414, 7545 and 7601).

    2. Section 80.91 is amended by revising paragraph (e)(7)(i); 
removing paragraph (e)(7)(iv) and by adding paragraphs (e)(8) and 
(e)(9) to read as follows:


Sec. 80.91  Individual baseline determination.

* * * * *
    (e) * * *
    (7) * * *
    (i) Baseline adjustments may be allowed, upon petition and approval 
(per Sec. 80.93), if a refinery produced JP-4 jet fuel in 1990 and all 
of the following requirements are also met:
    (A) Refinery type.
    (1) The refinery is the only refinery of a refiner such that it 
cannot form an aggregate baseline with another refinery (per 
Sec. 80.101(h)); or
    (2) The refinery is one refinery of a multi-refinery refiner for 
which all of the refiner's refineries produced JP-4 in 1990; or
    (3) The refinery is one refinery of a multi-refinery refiner for 
which not all of the refiner's refineries produced JP-4 in 1990.
    (B) No refinery of a given refiner produces reformulated gasoline. 
If any refinery of the refiner produces reformulated gasoline at any 
time in a calendar year, the compliance baselines of all the refiner's 
refineries receiving a baseline adjustment per this paragraph (e)(7) 
shall revert to the unadjusted baselines of each respective refinery 
for that year and all subsequent years.
    (C) 1990 JP-4 to gasoline ratio.
    (1) For a refiner per paragraph (e)(7)(i)(A)(1) of this section, 
the ratio of its refinery's 1990 JP-4 production to its 1990 gasoline 
production must be greater than or equal to 0.15.
    (2) For a refiner per paragraph (e)(7)(i)(A)(2) of this section, 
the ratio of each of its refinery's 1990 JP-4 production to its 1990 
gasoline production must be greater than or equal to 0.15.
    (3) For a refiner per paragraph (e)(7)(i)(A)(3) of this section, 
the ratio of the refiner's 1990 JP-4 production to its 1990 gasoline 
production must be greater than or equal to 0.15, when determined 
across all of its refineries. Such a refiner must comply with its anti-
dumping requirements on an aggregate basis, per Sec. 80.101(h), across 
all of its refineries.

    (8) Baseline adjustments due to increasing crude sulfur content.
    (i) Baseline adjustments may be allowed, upon petition and approval 
(per Sec. 80.93), if a refinery meets all of the following 
requirements:
    (A) The refinery does not produce reformulated gasoline. If the 
refinery produces reformulated gasoline at any time in a calendar year, 
its compliance baseline shall revert to its unadjusted baseline for 
that year and all subsequent years;
    (B) Has an unadjusted baseline sulfur value which is less than or 
equal to 50 parts per million (ppm);
    (C) Is not aggregated with one or more other refineries (per 
Sec. 80.101(h)). If a refinery which received an adjustment per this 
paragraph (e)(8) subsequently is included in an aggregate baseline, its 
compliance baseline shall revert to its unadjusted baseline for that 
year and all subsequent years;
    (D) Can show that installation of the refinery units necessary to 
process higher sulfur crude oil supplies to comply with the refinery's 
unadjusted baseline would cost at least $10 million or be greater than

of January 1, 1995;
    (E) Can show that it could not reasonably or economically obtain 
crude oil from an alternative source that would permit it to produce 
conventional gasoline which would comply with its unadjusted baseline;
