SULFUR CONTENT OF FUELS 

8.1 Definitions 

Unless otherwise expressly defined in this section, the terms used in this regulation shall be 

defined by reference to the Rhode Island Air Pollution Control General Definitions 

Regulation.. As used in this regulation, the following terms shall, where the context permits, 

be construed as follows: 

8.1.1 "Approved stack gas cleaning process" means a process, approved by the 

Director, which removes sulfur dioxide from the products of combustion of fossil 

fuel. 

8.1.2 "Fuel oil terminal" means a fuel oil storage and distribution facility that is 

supplied by pipeline or waterborne vessel, and from which fuel oil may be 

distributed at a loading rack into a truck, trailer, or railroad car. Fuel oil terminals 

may be supplied by additional means such as tank trucks or railroad cars. 

8.2 General Limitations 

, 

, no person shall store for sale, 

offer for sale, sell or deliver for use in Rhode Island and no person shall use any fuel 

oil having a sulfur content in excess of that in Table 1 except as provided in Section 

8.6.

8.2.2 No person shall store for sale, offer for sale, sell or deliver for use in Rhode Island 

and no person shall use any solid fossil fuel containing more than 0.55 pounds of 

sulfur per million Btu heat release potential. 

8.3 Exemptions 

8.3.1 Limitations with Stack Gas Cleaning Process 

The Director may approve the use of fuels that do not meet the requirements of 

Section 8.2 when combined with an approved stack gas cleaning process, provided 

the sulfur compound emissions (expressed as sulfur dioxide) from the stack are no 

greater than if the applicable sulfur content fuel were used. 

8.3.2 Fuel oil stored in Rhode Island that met the applicable requirements of subsection 

8.2.1 at the time the fuel oil was received for storage in Rhode Island may be stored 

for sale, offered for sale, sold or delivered for use or used after the effective date in 

subsection 8.2.1. 

8.3.3 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; or 

(b) The owner or operator of a stationary source using fuel oil shall obtain a 

certification from the fuel supplier which contains: 

(1) the name of the supplier and the date the fuel oil was received from 

the supplier; and, 

(2) the sulfur content of the fuel oil and the ASTM method used to 

determine the sulfur content of the fuel oil; and, 

(3) the date and location of the fuel oil when the sample was drawn for 

analysis to determine the sulfur content of the fuel oil , specifically 

including where the fuel oil was sampled; or 

(c) Laboratory analysis of fuel oils by the owner or operator of the stationary 

source or by the supplier. Sampling and analysis shall be conducted after 

Page 2 of 5 
each new shipment of fuel oil is received by the source. Samples shall be 

collected from the fuel tank immediately after the fuel tank is filled and 

before any fuel oil is combusted. All fuel oil must be sampled and analyzed 

in accordance with applicable ASTM methods or another method which has 

the prior approval of or are required by the Director; or 

(d) A continuous monitoring system for the measurement of sulfur dioxide 

that meets the performance specifications in Appendix B of 40 CFR 60. 

The monitoring equipment shall also be installed, calibrated, operated, and 

maintained in accordance with the procedures in Appendix B of 40 CFR 

60 and the minimum specifications in Appendix P of 40 CFR 51. 

8.4.2 Fuel Oil Terminals 

The owner or operator of a fuel oil terminal shall determine the sulfur content of any 

fuel oil sold that is subject to the sulfur content limitations in Table 1 of this 

regulation and provide certification of the sulfur content of the fuel oil to each 

purchaser of the fuel. Certifications shall meet the requirements of subsection 

8.4.1(b)(1)-(3). All fuel oil must be sampled and analyzed in accordance with 

applicable ASTM methods or another method which has the prior approval of or are 

required by the Director.

The Director may require, under his supervision, the collection of fossil fuel samples 

for the purpose of determining compliance with this regulation. 

8.5 Recordkeeping 

8.5.1 Copies of all fuel supplier certifications or fuel oil analyses shall be maintained by 

the owner or operator and be made accessible for review by the Office of Air

8.5.2 All records required by this regulation shall be maintained for a minimum of five 

years after the date of each record and shall be made available to representatives 

of the Office of Air Resources upon request. 

8.6 Blending of Fuel Oils 

8.6.1 A fuel oil terminal may receive and store, but not offer for sale, sell or deliver for 

use in Rhode Island, fuel oil that does not meet the sulfur content limitations in 

Table 1 of this regulation, if it meets the following conditions: 

(a) The higher sulfur fuel will be blended with lower sulfur fuel to meet the 

sulfur content limitations in Table 1 of this regulation; and, 

Page 3 of 5 
(b) Notifies the Director, in writing, of its intention to store and blend fuel oil 

that does not meet the sulfur content limitations in Table 1 of this
