General Limitations
Unless the Director declares in writing after a hearing that a shortage of low sulfur
fuel exists, no person shall store for sale, offer for sale, sell or deliver for use in
Rhode Island and no person shall use or store high sulfur fuel except as provided in
Section 8.3.
8.3
Exceptions
8.3.1 Limitations with Stack Gas Cleaning Process
The Director may approve the use of high sulfur fuel when combined with an
approved stack gas cleaning process, provided the sulfur compound emissions
(expressed as sulfur dioxide) from the stack do not exceed 1.1 pounds per
million Btu actual heat input, and the person using such process gives evidence
satisfactory to the Director that the emissions do not exceed the requirements of
this subsection.
8.3.2 Emission Bubbling
The provisions of Section 8.2 shall not apply to fuels included in an emissions
bubble. In an emissions bubble, the owner or operator of a source with more
than one fuel burning device, each of which is subject to specific emission
requirements under the applicable regulations, may propose to meet the total
emission control requirements of the applicable regulations, for a given
pollutant, through a different mix of control technology than that mandated by
Page 3 of 12
existing regulations. Sulfur compound emissions (expressed as sulfur dioxide)
from such a bubble shall not exceed 1.1 pounds per million Btu actual heat
input and the sulfur content of any fuel used within the bubble shall not contain
over 1.21 pounds of sulfur per million Btu heat release potential. Particulate
emissions from the bubble shall not exceed 0.10 pounds per million Btu actual
heat input and particulate emissions from any single fuel burning device within
the bubble shall not exceed 0.15 pounds per million Btu actual heat input.
(a)
It is the responsibility of the owner or operator of the source to develop a
specific emission bubble. Application for approval of an emission
bubble shall be made to the Department and must include the following:
(1) Certification that all fuel burning devices to be included in the
emissions bubble are at the same plant location and are under the
control of, or operated by, the same person; and
(2) Identification of each fuel burning device and stack to be included in
the emissions bubble, including the types of fuel to be burned in
each unit, the maximum sulfur content of each fuel, the heat input
capacity for each unit, the annual fuel use and operating hours per
year for each unit; and for each stack, the physical stack height; the
exit velocity of the stack gas, the inside diameter of the stack exit
and the exit stack gas temperature; and
(3) Sufficient information to evaluate aerodynamic downwash effects
in accordance with all applicable federal requirements; and
(4) Air quality modeling meeting the requirements of the Rhode Island
Guideline for Air Quality Modeling, including aerodynamic
downwashing modeling, to demonstrate that the bubble will not
cause a violation of any National Ambient Air Quality Standard, or
applicable PSD increment, and will not have a significant impact
on any nonattainment area or Class I PSD area. If there is no
increase in actual emissions, the air quality modeling requirement
may be waived under the following conditions:
(i)
All the fuel burning devices included in the bubble discharge
through the same stack; or
(ii)
Emissions from the most polluting fuel are released at an
effective stack height within 10 percent of the greatest
effective stack height within the bubble and all stacks
included in the bubble are co-located. Co-located shall be
held to mean within 100 meters of each other.
Page 4 of 12
(b)
The Department shall not approve any emissions bubble without first
giving public notice and affording all interested persons opportunity to
comment on the emissions bubble. Additionally, the Department shall
notify the public after each final approval.
(c)
An emissions bubble shall not allow a source to supersede any of the
following applicable conditions or standards:
(1) Conditions of any Prevention of Significant Deterioration permit;
or
(2) Conditions of any nonattainment area permit; or
(3) Federal New Source Performance Standards; or
(4) National Emissions Standards for Hazardous Air Pollutants.
(d)
An approved bubble shall be in effect for a period of no more than three
years from the date of issuance. At the end of such three-year period, the
Department shall review the bubble for compliance and may either
terminate or extend approval of the bubble based on consideration of air
quality, control technology innovation, and such other determinations as
the Department deems appropriate.
(e)
The provisions of any bubble shall be incorporated in a permit issued in
accordance with the provisions of Air Pollution Control Regulation 9.
(f)
Any bubble approved by the Department and incorporated into the State
Implementation Plan prior to the effective date of this regulation may be
continued at the discretion of the Department, subject to the provisions of
paragraphs (c), (d) and (e) of this subsection..
8.3.3 Conversion and Conservation Incentive
The Department may authorize the use of high sulfur fuel oil for a period of up
to 30 months in any fuel burning device with an energy input capacity of less
than 250 million Btu's per hour. The use of the high sulfur fuel oil will be
contingent on the source committing to implement permanent energy
conservation measures to convert to a fuel (other than a petroleum product such
as coal, wood, coal-oil mixture, etc.). The savings realized from burning high
sulfur fuel oil during this period shall be used to finance the necessary
modifications or installation of pollution control equipment.
Page 5 of 12
(a) Approval for burning of high sulfur fuel oil under this section may be
granted provided that:
(1) The applicant demonstrates by means of air quality modeling, including
aerodynamic downwash modeling meeting the requirements of the
Rhode Island Guideline for Air Quality Monitoring, that the increase in
sulfur dioxide and particulate emissions resulting from the use of the
high sulfur fuel oil will not cause a violation of any National Ambient
Air Quality Standard or any applicable PSD increment and will not have
a significant impact on any nonattainment area or Class I PSD area; and
(2) The applicant enters into a Consent Agreement with the Department that
specifies a schedule with deadlines by which time various aspects of the
conversion and installation of pollution control equipment or the
implementation of energy conservation measures shall be completed. .In
no event shall final installation of pollution control equipment and
completion of the conversion or complete implementation of energy
conservation measures be accomplished more than 30 months from the
commencement of installation unless the Department finds good cause
for a longer time. Financial difficulty will not be considered a good
cause; and
(3) The applicant agrees to submit to the Department a quarterly report
stating the quantity of high sulfur fuel oil used, the cost of fuel, the cost
of an equivalent quantity of low sulfur fuel oil and the hours of operation
for the high sulfur fuel burning unit; and
(4) The applicant, where practicable and deemed necessary by the
Department, shall have a three-day supply of low sulfur fuel oil on hand
and be prepared to convert as soon as possible after receiving notice
from the Department. If the above is not practicable, then, at a
minimum, the company shall have a commitment from its fuel oil
supplier to supply the low sulfur fuel within a specified time; and
(5) If the conversion does not take place or the energy conversion measures
are equivalent to the difference between the cost of the high sulfur fuel
oil used and the equivalent amount of low sulfur fuel oil. The applicant
shall put up a bond for the amount of money estimated to be saved
during the burning of high sulfur fuel oil. This money shall be forfeited
if the final conversion or implementation of energy conservation
measures does not take place; and
(6) If the applicant implements permanent energy conservation measures,
they must reduce oil consumption by at least 50,000 gallons/year below
Page 6 of 12
average consumption in the two calendar years immediately preceding
the 30-month period. The applicant can continue to burn high sulfur fuel
after the 30-month period if, through the use of permanent energy
conservation measures, annual oil consumption has been reduced by 56
percent from the average annual consumption during the two calendar
years immediately preceding the 30- month period; and
(7) In the case of conversion, the capacity of the unit that will be converted
or installed shall be at least equal to the estimated average heat input rate
of high sulfur fuel oil during the 30-month period. This requirement
may be waived by the Director if, in his judgment, an increase in the
efficiency of the unit due to conversion would decrease the required
capacity of the converted unit; and
(8) Approval to burn high sulfur oil shall be granted for only one 30- month
period per facility. Such approval may not be renewed or extended
except as provided in paragraph 8.3.3(a)(6). After the 30- month period,
the source must meet the sulfur dioxide and particulate emission
standards which were in effect prior to the approval, except if an
applicable standard is amended during the 30-month period, in which
case the source may elect to meet the new standard; or except as may be
allowed under paragraph 8.3.3(a)(6). Additionally, the applicant must
agree to conduct stack testing of any converted unit at his expense to
verify compliance with applicable standards for sulfur dioxide and
particulates. The Department may, where appropriate, approve fuel
testing rather than stack testing for determining compliance with sulfur
dioxide emission limits; and
(9) The sulfur content of the high sulfur fuel oil used in this section shall not
exceed 1.21 pounds of sulfur per million Btu actual heat input.
(b) An application for approval under this section shall be made to the Department
and must include the following:
(1) The required air quality modeling; and
(2) A proposed schedule for completing conversion or for implementing
conservation measures; and
(3) Information on any proposed modifications intended to be made at the
facility before it burns high sulfur oil; and
(4) For conversions, information on the facility as it will exist after the
conversion; and
Page 7 of 12
(5) For conservation applications, a listing of each conservation measure
and a preliminary estimate of the fuel savings expected; and
(6) Historical fuel usage for the facility and preliminary estimates of the
quantity of high sulfur fuel oil to be consumed and the total hours
burning of high sulfur fuel oil that will take place.
(c) Any fuel burning device included in a plan under this section must have been
installed and in operation prior to the effective date of this regulation.
8.3.4 Large Fuel Burning Devices Using Coal
(a) Any fuel burning device with a rated energy input capacity of 250 million
Btu's per hour or more may use high sulfur fuel provided that:
(1) the high sulfur fuel is coal; and
(2) the average sulfur content does not exceed 1.21 pounds per million Btu's
heat release potential in any 30-day period of 2.31 pounds per million
Btu's in any 24-hour period; and
(3) the stack height, from which emissions resulting from the burning of the
high sulfur fuel exit, meets or exceeds good engineering practice; and
(4) emissions resulting from the use of the high sulfur fuel will not cause a
violation of any National Ambient Air Quality Standard or any
applicable PSD increment and will not have a significant impact on any
nonattainment area.
(b) It is the responsibility of the owner or operator of the facility to provide
evidence, satisfactory to the Department, and meeting the requirements of the
Rhode Island Guideline for Air Quality Modeling, that the above conditions
are met.
(c) If any new or amended federal law requires a reduction in the total emissions
of sulfur oxides or nitrogen oxides in Rhode Island or sets a maximum limit on
such emissions, then the owner or operator of a facility burning high sulfur fuel
under the provisions of paragraph 8.3.4(a) must obtain emission offsets or
emission reductions for the increased sulfur oxide emissions due to coal
burning.
(1) The actual amount of emission offsets or emission reductions at any time
shall be the difference between the actual annual sulfur oxide emission
Page 8 of 12
rate and the actual annual sulfur oxide emission rate during the baseline
period established by federal law; except that the amount of emission
offsets or reductions required shall be reduced to the extent that the new
or amended federal law does not count the increased sulfur oxide
emissions due to coal burning as part of the maximum allowable
emissions for sulfur oxides and nitrogen oxides in Rhode Island.
(2) Such emission offsets or emission reductions must meet any conditions
specified in federal law to be creditable against Rhode Island sulfur
oxide and nitrogen oxide emissions and must be obtained within the
period established by the new or amended federal law
(3) The Director may waive any or all of the required emission offsets or
emission reductions at his discretion, provided that the total emissions of
sulfur oxides and nitrogen oxides in Rhode Island shall not exceed the
maximum amount allowed under federal law.
8.3.5 Storage Facilities
Any person seeking to store for sale, sell or deliver, high sulfur fuel for use in
Rhode Island under the provisions of Subsections 8.3.1, 8.3.2, 8.3.3 and 8.3.4 or
for use outside of Rhode Island shall obtain the prior written approval of the
Director.
8.3.6 Exemptions
The limitations of this regulation shall not apply to marine vessels or motor vehicles.
8.4
Determination of Compliance
8.4.1 Compliance with the applicable limitations set forth in this regulation shall be
determined by procedures referenced below or deemed equivalent by the
Director. Such procedures shall include but not be limited to any of the
following:
(a) Emission testing conducted by the owner or operator of the source according
to the Reference Methods of Appendix A to 40 CFR 60; and
(b) Laboratory analysis of fossil fuels by the owner or operator of the source or by
the supplier. A sampling valve shall be installed in the fuel line between the
feed pump and the burner by the owner or operator for sample collection.
Fossil fuels must be sampled and analyzed according to ASTM methods which
have the prior approval or are required by the Director.

POLICY FOR INCREMENT CONSUMPTION FROM APPLICATION UNDER
SECTION 8.3.3 OF REGULATION 8 - 14 MARCH 1985
As part of an application under the Conversion and Conservation Incentive Section of Regulation 8,
the applicant must demonstrate "...that the increase in sulfur dioxide and particulate emissions
resulting from the use of the high sulfur oil will not cause a violation of ... any applicable PSD
increment..."
Air Pollution Control Regulation 9, Section 9.15, contains the rules governing increment
consumption, and these requirements supersede those of any other regulations. Section 9.15.1 (c)
allows for the exclusion of certain concentrations from increment consumption. One such exclusion
is for "...concentrations attributable to the temporary increase in emissions of sulfur dioxide of
particulate matter from stationary sources which are affected by State Implementation Plan revisions
meeting the following criteria:
(a) The duration of the State Implementation Plan revision shall not exceed thirty (30)
months; and
(b) The duration of the exclusion is not renewable; and
(c) The emissions increase from the source would not cause or contribute to the violation of
a national ambient air quality standard or impact an area where an applicable increment
is known to be violated; and
(d) At the end of the State Implementation Plan revision, the emission levels from the
source shall not exceed those levels occurring before the State Implementation Plan
revision was approved..."
Any approval under the Conversion and Conservation Incentive Section of Regulation 8 would
satisfy all of these criteria. Therefore, in general, applications under Section 8.3.3 will no longer be
required to assess increment consumption as part of the application. If, however, an applicant will
have a significant impact in either Massachusetts or Connecticut, it will be required to assess
increment consumption in that state.
For those applications where the impacts are in Rhode Island only, the applicant will be required to
assess compliance with the applicable NAAQS, impacts on nonattainment areas, impacts on Class I
PSD areas and impacts on any area where an increment is known to be violated.
