(a) Baseline definition. (1) The "baseline" or "individual baseline"
of a refinery, refiner or importer, as applicable, shall consist of:
(i) An estimate of the quality, composition and volume of its 1990 gasoline,
or allowable substitute, based on the requirements specified in §§80.91 through
80.93; and
(ii) Its baseline emissions values calculated per paragraph (f) of this
section.
(2)(i) The quality and composition of the 1990 gasoline of a refinery,
refiner or importer, as applicable, shall be the set of values of the following
fuel parameters: benzene content; aromatic content; olefin content; sulfur
content; distillation temperature at 50 and 90 percent by volume evaporated;
percent evaporated at 200 °F and 300 °F; oxygen content; RVP.
(ii) A refiner, per paragraph (b)(3)(i) of this section, shall also determine
the API gravity of its 1990 gasoline.
(3) The methodology outlined in this section shall be followed in determining
a baseline value for each fuel parameter listed in paragraph (a)(2) of this
section.
(b) Requirements for refiners, blenders and importers -- (1)
Requirements for producers of gasoline and gasoline blendstocks. (i) A
refinery engaged in the production of gasoline blendstocks from crude oil and/or
crude oil derivatives, and the subsequent mixing of those blendstocks to form
gasoline, shall have its baseline fuel parameter values determined from Method
1, 2 and/or 3-type data as described in paragraph (c) of this section, provided
the refinery was in operation for at least 6 months in 1990.
(ii) A refinery which was in operation for at least 6 months in 1990, was
shut down after 1990, and which restarts after June 15, 1994, and for which
insufficient 1990 and post-1990 data was collected prior to January 1, 1995 from
which to determine an individual baseline, shall have the values listed in
paragraph (c)(5) of this section as its individual baseline parameters.
(iii) A refinery which was in operation for less than 6 months in 1990 shall
have the values listed in paragraph (c)(5) of this section as its individual
baseline parameters.
(2) Requirements for producers or importers of gasoline blendstocks
only. A refiner or importer of gasoline blendstocks which did not produce or
import gasoline in 1990 and which produces or imports post-1994 gasoline shall
have the values listed in paragraph (c)(5) of this section as its individual
baseline parameters.
(3) Requirements for purchasers of gasoline and/or gasoline
blendstocks. (i) A refiner or refinery, as applicable, solely engaged in the
production of gasoline from gasoline blendstocks and/or gasoline which are
simply purchased and blended to form gasoline shall have its individual baseline
determined using Method 1-type data (per paragraph (c) of this section) from
every batch of 1990 gasoline.
(ii) If Method 1-type data on every batch of the refiner's or refinery's 1990
gasoline does not exist, that refiner or refinery shall have the values listed
in paragraph (c)(5) of this section as its individual baseline parameters.
(4) Requirements for importers of gasoline and/or gasoline
blendstocks. (i) An importer of gasoline shall determine an individual
baseline value for each fuel parameter listed in paragraph (a)(2) of this
section using Method 1-type data on every batch of gasoline imported by that
importer into the United States in 1990.
(ii) An importer which is also a foreign refiner must determine its
individual baseline using Method 1, 2 and/or 3-type data (per paragraph (c) of
this section) if it imported at least 75 percent, by volume, of the gasoline
produced at its foreign refinery in 1990 into the United States in 1990.
(iii) An importer which cannot meet the criteria of paragraphs (b)(4)(i) or
(ii) of this section for baseline determination shall have the parameter values
listed in paragraph (c)(5) of this section as its individual baseline parameter
values.
(5) Requirements for exporters of gasoline and/or gasoline
blendstocks. A refiner shall not include quality or volume data on its 1990
exports of gasoline blendstocks or gasoline in its baseline determination.
(c) Data types -- (1) Method 1-type data. (i) Method 1-type
data shall consist of quality (composition and property data) and volume records
of gasoline produced in or shipped from the refinery in 1990, excluding exported
gasoline. The measured fuel parameter values and volumes of batches, or
shipments if not batch blended, shall be used except that data on produced
gasoline which was also shipped shall be included only once.
(ii) Gasoline blendstock which left a facility in 1990 and which could become
gasoline solely upon the addition of oxygenate shall be included in the baseline
determination.
(A) Fuel parameter values of such blendstock shall be accounted for as if the
gasoline blendstock were blended with ten (10.0) volume percent ethanol.
(B) If the refiner or importer can provide evidence that such gasoline
blendstock was not blended per paragraph (c)(1)(ii)(A) of this section, and that
such gasoline blendstock was blended with another oxygenate or a different
volume of ethanol, the fuel parameter values of the final gasoline (including
oxygenate) shall be included in the baseline determination.
(C) If the refiner or importer can provide evidence that such gasoline
blendstock was not blended per paragraph (c)(1)(ii)(A) or (B) of this section,
and that such gasoline blendstock was sold with out further changes downstream,
the fuel parameter values of the original product shall be included in the
baseline determination.
(iii) Data on 1990 gasoline purchased or otherwise received, including
intracompany transfers, shall not be included in the baseline determination of a
refiner's or importer's facility if the gasoline exited the receiving refinery
unchanged from its arrival state.
(2) Method 2-type data. Method 2-type data shall consist of 1990
gasoline blendstock quality data and 1990 blendstock production records,
specifically the measured fuel parameter values and volumes of blendstock used
in the production of gasoline within the refinery. Blendstock data shall include
volumes purchased or otherwise received, including intracompany transfers, if
the volumes were blended as part of the refiner's or importer's 1990 gasoline.
Henceforth in §§80.91 through 80.93, "blendstock(s)" or "gasoline blendstock(s)"
shall include those products or streams commercially blended to form gasoline.
(3) Method 3-type data. (i) Method 3-type data shall consist of
post-1990 gasoline blendstock and/or gasoline quality data and 1990 blendstock
and gasoline production records, specifically the measured fuel parameter values
and volumes of blendstock used in the production of gasoline within the
refinery. Blendstock data shall include volumes purchased or otherwise received,
including intracompany transfers, if the volumes were blended as part of the
refiner's or importer's 1990 gasoline.
(ii) In order to use Method 3-type data, the refiner or importer must do all
of the following:
(A) Include a detailed discussion comparing its 1990 and post-1990 refinery
operations and all other differences which would cause the 1990 and post-1990
fuel parameter values to differ; and
(B) Perform the appropriate calculations so as to adjust for the differences
determined in paragraph (c)(3)(ii)(A) of this section; and
(C) Include a narrative, discussing the methodology and reasoning for the
adjustments made per paragraph (c)(3)(ii)(B) of this section.
(iii) In order to use post-1990 gasoline data, either of the following must
be shown for each blendstock-type included in 1990 gasoline, excluding butane:
(A) The post-1990 volumetric fraction of a blendstock is within (±)10.0
percent of the volumetric fraction of that blendstock in 1990 gasoline. For
example, if a 1990 blendstock constituted 30 volume percent of 1990 gasoline,
this criterion would be met if the post-1990 volumetric fraction of the
blendstock in post-1990 gasoline was 27.0-33.0 volume percent.
(B) The post-1990 volumetric fraction of a blendstock is within (±)2.0 volume
percent of the absolute value of the 1990 volumetric fraction. For example, if a
1990 blendstock constituted 5 volume percent of 1990 gasoline, this criterion
would be met if the post-1990 volumetric fraction of the blendstock in post-1990
gasoline was 3-7 volume percent.
(iv) If using post-1990 gasoline data, post-1990 gasoline blendstock which
left a facility and which could become gasoline solely upon the addition of
oxygenate shall be included in the baseline determination, per the requirements
specified in paragraph (c)(1)(ii) of this section.
(4) Hierarchy of data use. (i) A refiner or importer must determine a
baseline fuel parameter value using only Method 1-type data if sufficient Method
1-type data is available, per paragraph (d)(1)(ii) of this section.
(ii) If a refiner has insufficient Method 1-type data for a baseline
parameter value determination, it must supplement that data with all available
Method 2-type data, until it has sufficient data, per paragraph (d)(1)(iii) of
this section.
(iii) If a refiner has insufficient Method 1- and Method 2-type data for a
baseline parameter value determination, it must supplement that data with all
available Method 3-type data, until it has sufficient data, per paragraph
(d)(1)(iii) of this section.
(iv) The protocol for the determination of baseline fuel parameter values in
paragraphs (c)(4)(i) through (iii) of this section shall be applied to each fuel
parameter one at a time.
(5) Anti-dumping statutory baseline. (i) The summer anti-dumping
statutory baseline shall have the set of fuel parameter values identified as
"summer" in §80.45(b)(2). The anti-dumping summer API gravity shall be 57.4
°API.
(ii) The winter anti-dumping statutory baseline shall have the set of fuel
parameter values identified as "winter" in §80.45(b)(2), except that winter RVP
shall be 8.7 psi. The anti-dumping winter API gravity shall be 60.2 API.
(iii) The annual average anti-dumping statutory baseline shall have the
following set of fuel parameter values:
Benzene, volume percent -- 1.60
Aromatics, volume percent -- 28.6
Olefins, volume percent -- 10.8
RVP, psi -- 8.7
T50, degrees F -- 207
T90, degrees F -- 332
E200, percent -- 46
E300, percent -- 83
Sulfur, ppm -- 338
API Gravity, °API -- 59.1
(iv) The annual average anti-dumping statutory baseline shall have the
following set of emission values:
Exhaust benzene emissions, simple model -- 6.45
Exhaust benzene emissions, complex model -- 33.03 mg/mile
Exhaust toxics emissions, Phase I -- 50.67 mg/mile
Exhaust toxics emissions, Phase II -- 104.5 mg/mile
NOX emissions, Phase I -- 714.4 mg/mile
NOX emissions, Phase II -- 1461. mg/mile
(d) Data collection and testing requirements -- (1) Minimum
sampling requirements -- (i) General requirements. (A) Data shall
have been obtained for at least three months of the refiner's or importer's
production of summer gasoline and at least three months of its production of
winter gasoline. When method 1 per batch RVP data is available, a month is
considered equivalent to 4 weeks of seasonal data.
(1) Method 1, per batch, actual RVP data will be used to define that
batch as either summer fuel or winter fuel. Summer fuel is defined as fuel
produced and intended for sale to satisfy Federal summer volatility standards.
When such per batch actual RVP data is not available, data is allocated per
month as follows. A summer month is defined as any month during which more than
50 percent (by volume) of the gasoline produced by a refiner met the Federal
summer gasoline volatility requirements. Winter shall be any month which could
not be considered a summer month under this definition.
(2) The three months which compose the summer and the winter data do
not have to be consecutive nor within the same year.
(3) If, in 1990, a refiner marketed all of its gasoline only in an
area or areas which experience no seasonal changes relative to gasoline
requirements, e.g., Hawaii, only 3 months of data are required.
(B) Once the minimum sampling requirements have been met, data collection may
cease. Additional data may only be included for the remainder of the calendar
year in which the minimum sampling requirements were met. In any case, all data
collected through the date of collection of the last data point included in the
determination of a baseline fuel parameter value must be utilized in the
baseline determination of that fuel parameter.
(C) Less than the minimum requirements specified in paragraph (d)(1) of this
section may be allowed, upon petition and approval (per §80.93), if it can be
shown that the available data is sufficient in quality and quantity to use in
the baseline determination.
(ii) Method 1 sampling requirements. At least half of the batches, or
shipments if not batch blended, in a calendar month shall have been sampled over
a minimum of six months in 1990.
(iii) Method 2 sampling requirements. (A) Continuous blendstock
streams shall have been sampled at least weekly over a minimum of six months in
1990.
(B) For blendstocks produced on a batch basis, at least half of all batches
of a single blendstock type produced in a calendar month shall have been sampled
over a minimum of six months in 1990.
(iv) Method 3 sampling requirements -- (A) Blendstock data. (1)
Post-1990 continuous blendstock streams shall have been sampled at least weekly
over a minimum of six months.
(2) For post-1990 blendstocks produced on a batch basis, at least half
of all batches of a single blendstock type produced in a calendar month shall
have been sampled over a minimum of six months.
(B) Gasoline data. At least half of the post-1990 batches, or
shipments if not batch blended, in a calendar month shall have been sampled over
a minimum of six months in order to use post-1990 gasoline data.
(2) Sampling beyond today's date. The necessity and actual occurrence
of data collection after today's date must be shown.
(3) Negligible quantity sampling. Testing of a blendstock stream for a
fuel parameter listed in this paragraph (d)(3) is not required if the refiner
can show that the fuel parameter exists in the stream at less than or equal to
the amount, on average, shown in this paragraph (d)(3) for that fuel parameter.
Any fuel parameter shown to exist in a refinery stream in negligible amounts
shall be assigned a value of 0.0:
Aromatics, volume percent -- 1.0
Benzene, volume percent -- 0.15
Olefins, volume percent -- 1.0
Oxygen, weight percent -- 0.2
Sulfur, ppm -- 30.0
(4) Sample compositing. (i) Samples of gasoline or blendstock which
have been retained, but not analyzed, may be mixed prior to analysis and
analyzed, as described in paragraphs (d)(4)(iii) (A) through (H) of this
section, for the required fuel parameters. Samples must be from the same season
and year and must be of a single grade or of a single type of batch-produced
blendstock.
(ii) Blendstock samples of a single blendstock type obtained from continuous
processes over a calendar month may be mixed together in equal volumes to form
one blendstock sample and the sample subsequently analyzed for the required fuel
parameters.
(iii)(A) Samples shall have been collected and stored per the method normally
employed at the refinery in order to prevent change in product composition with
regard to baseline properties and to minimize loss of volatile fractions of the
sample.
(B) Properties of the retained samples shall be adjusted for loss of butane
by comparing the RVP measured right after blending with the RVP determined at
the time that the supplemental properties are measured.
(C) The volume of each batch or shipment sampled shall have been noted and
the sum of the volumes calculated to the nearest hundred (100) barrels.
(D) For each batch or shipment sampled, the ratio of its volume to the total
volume determined in paragraph (d)(4)(iii)(C) of this section shall be
determined to three (3) decimal places. This shall be the volumetric fraction of
the shipment in the mixture.
(E) The total minimum volume required to perform duplicate analyses to obtain
values of all of the required fuel parameters shall be determined.
(F) The volumetric fraction determined in paragraph (d)(4)(iii)(D) of this
section for each batch or shipment shall be multiplied by the value determined
in paragraph (d)(4)(iii)(E) of this section.
(G) The resulting value determined in paragraph (d)(4)(iii)(F) of this
section for each batch or shipment shall be the volume of each batch or
shipment's sample to be added to the mixture. This volume shall be determined to
the nearest milliliter.
(H) The appropriate volumes of each shipment's sample shall be thoroughly
mixed and the solution analyzed per the methods normally employed at the
refinery.
(5) Test methods. (i) If the test methods used to obtain fuel
parameter values of gasoline and gasoline blendstocks differ or are otherwise
not equivalent in precision or accuracy to the corresponding test method
specified in §80.46, results obtained under those procedures will only be
acceptable, upon petition and approval (per §80.93), if the procedures are or
were industry-accepted procedures for measuring the properties of gasoline and
gasoline blendstocks at the time the measurement was made.
(ii) Oxygen content may have been determined analytically or from oxygenate
blending records.
(A) The fuel parameter values, other than oxygen content, specified in
paragraph (a) of this section, must be established as for any blendstock, per
the requirements of this paragraph (d).
(B) All oxygen associated with allowable gasoline oxygenates per §80.2(jj)
shall be included in the determination of the baseline oxygen content, if oxygen
content was determined analytically.
(C) Oxygen content shall be assumed to be contributed solely by the oxygenate
which is indicated on the blending records, if oxygen content was determined
from blending records.
(6) Data quality. Data may be excluded from the baseline determination
if it is shown to the satisfaction of the Director of the Office of Mobile
Sources, or designee, that it is not within the normal range of values expected
for the gasoline or blendstock sample, considering unit configuration, operating
conditions, etc.; due to:
(i) Improper labeling; or
(ii) Improper testing; or
(iii) Other reasons as verified by the auditor specified in §80.92.
(e) Baseline fuel parameter determination -- (1) Closely integrated
gasoline producing facilities. Each refinery or blending facility must
determine a set of baseline fuel parameter values per this paragraph (e). A
single set of baseline fuel parameters may be determined, upon petition and
approval, for two or more facilities under either of the following
circumstances:
(i) Two or more refineries or sets of gasoline blendstock-producing units of
a refiner engaged in the production of gasoline per paragraph (b)(1) of this
section which are geographically proximate to each other, yet not within a
single refinery gate, and whose 1990 operations were significantly
interconnected.
(ii) A gasoline blending facility operating per paragraph (b)(3) of this
section received at least 75 percent of its 1990 blendstock volume from a single
refinery, or from one or more refineries which are part of an aggregate baseline
per §80.101(h). The blending facility and associated refinery(ies) must be owned
by the same refiner.
(iii) For facilities determined to be closely integrated gasoline producing
facilities and for which EPA has granted a single set of baseline fuel parameter
values per this paragraph (e)(1)(i):
(A) All reformulated gasoline and anti-dumping standards shall be met by such
closely integrated facilities on an aggregate basis;
(B) A combined facility registration shall be submitted under §§80.76 and
80.103; and
(C) Record keeping requirements under §§80.74 and 80.104 and reporting
requirements under §§80.75 and 80.105 shall be met for such closely integrated
facilities on an aggregate basis.
(2) Equations -- (i) Parameter determinations. Average baseline
fuel parameters shall be determined separately for summer and winter using
summer and winter data (per paragraph (d)(1)(i)(A) of this section),
respectively, in the applicable equation listed in paragraphs (e)(2) (ii)
through (iv) of this section, except that average baseline winter RVP shall be
8.7 psi.
(ii) Product included in parameter determinations. In each of the
equations listed in paragraphs (e)(2) (ii) through (iv) of this section, the
following shall apply:
(A) All gasoline produced to meet EPA's 1990 summertime volatility
requirements shall be considered summer gasoline. All other gasoline shall be
considered winter gasoline.
(B)(1) Baseline total annual 1990 gasoline volume shall be the larger
of the total volume of gasoline produced in or shipped from the refinery in
1990.
(2) Baseline summer gasoline volume shall be the total volume of low
volatility gasoline which met EPA's 1990 summertime volatility requirements.
Baseline summer gasoline volume shall be determined on the same basis (produced
or shipped) as baseline total annual gasoline volume.
(3) Baseline winter gasoline volume shall be the baseline total annual
gasoline volume minus the baseline summer gasoline volume.
(C) Fuel parameter values shall be determined in the same units and at least
to the same number of decimal places as the corresponding fuel parameter listed
in paragraph (c)(5) of this section.
(D) Volumes shall be reported to the nearest barrel or to the degree at which
historical records were kept.
(iii) Method 1. Summer and winter Method 1-type data, per paragraph
(c)(1) of this section, shall be evaluated separately according to the following
equation:
