Control of Volatile Organic Compounds from Marine Vessel Loading Operations (250-RICR-120-05-32)

The purpose of this regulation is to limit volatile organic compound emissions from marine vessel loading operations.

These regulations are authorized pursuant to R.I. Gen. Laws § 42-17.1-2(19) and Chapter 23-23, and have been promulgated pursuant to the procedures set forth in the R.I. Administrative Procedures Act, R.I. Gen. Laws Chapter 42-35.

The terms and provisions of this regulation shall be liberally construed to permit the Department to effectuate the purposes of state laws, goals and policies.

If any provision of this regulation or the application thereof to any person or circumstance, is held invalid by a court of competent jurisdiction, the validity of the remainder of the regulation shall not be affected thereby.

A.Unless otherwise expressly defined in this section, the terms used in this regulation shall be defined by reference to (General Definitions), Part 0 of this Subchapter. As used in this regulation, the following terms shall, where the context permits, be construed as follows:

1."Combustion device" means emission control equipment used for combustion or destruction of organic vapors and includes, but is not limited to, thermal incinerators, catalytic incinerators, flares, boilers, and process heaters.

2."Emission control equipment" means any equipment, machinery, apparatus, or device used to recover or reduce emissions of volatile organic compounds.

3."Gasoline" means any petroleum distillate having a Reid vapor pressure of more than 4 psia as determined by ASTM Method D323. This term includes but is not limited to mixtures of alcohols and gasoline.

4."Leak free" means the dripping of a liquid containing volatile organic compounds at a rate of four drops per minute or less; or an emission of gaseous volatile organic compounds which causes an appropriate analyzer sampling one centimeter or less from a source to register less than 10,000 ppm as methane.

5."Loading event" means an incident or occurrence beginning with the connecting of marine terminal storage tanks to a marine tank vessel by means of pipes or hoses followed by the transferring of organic liquid cargo and ending with the disconnecting of the pipes or hoses; or any means of admitting any other liquid into a marine vessel's cargo tanks. Loading events shall include only such incidents which occur when a marine tank vessel is moored to a dock or other permanent stationary structure.

6."Marine tank vessel" means any marine vessel which is specially constructed or converted to carry liquid bulk cargo in tanks.

7."Marine terminal" means any facility, equipment, or structure constructed to load or unload organic liquid bulk cargo into or out of marine tank vessels.

8."Marine vessel" means any tugboat, tanker, freighter, passenger ship, barge or other boat, ship or water craft except those used primarily for recreation.

9."Organic liquid" means, for the purposes of this regulation, gasoline, gasoline blending stocks, aviation gas and aviation fuel which contains gasoline, such as JP-4 type.

10."Recovery device" means emission control equipment used to remove organic vapors and recover liquids or chemicals and includes, but is not limited to, absorbers, carbon absorbers, and condensers.

11."Segregated ballasting operations" means the loading of ballast water into tanks on a marine vessel if those tanks are used only for ballasting and never hold organic liquid.

12."Vapor tight marine vessel" means a marine vessel which has been demonstrated within the previous 12 months to have no leaks. A marine vessel loaded at negative pressure is assumed to be vapor tight for the purposes of this regulation. Discharges from pressure/vacuum relief valves on cargo tank vent lines are not considered leaks for the purposes of this definition.

A.The provisions of this regulation apply to any loading event in which organic liquid is loaded into marine tank vessels and to loading events in which any liquid is loaded into a marine vessel's cargo tanks if the most recent cargo held in those tanks was an organic liquid. This regulation does not apply to segregated ballasting operations.

B.Wherever the term Volatile Organic Compound or VOC is used in §§ 32.6 through 32.10 of this Part, this term should be read as Volatile Organic Compound and Halogenated Organic Compound or VOC and HOC.

A.A loading event shall not be conducted unless one of the following conditions is met:

1.Volatile organic compounds emissions do not exceed 5.7 grams per cubic meter (2 pounds per 1000 barrels) of liquid loaded into the marine tank vessel, or,

2.The emissions of volatile organic compounds are reduced by at least 95 percent by weight from uncontrolled conditions if a recovery device is used and by at least 98 percent by weight from uncontrolled conditions if a combustion device is used.

B.All of a marine terminal's hatches, pressure relief valves, connections, gauging ports and vents which are used in connection with a loading event shall be leak free.

C.A loading event shall not be conducted unless the receiving marine vessel is vapor tight. To determine whether a marine vessel is vapor tight, the owner or operator of the marine terminal must follow the following procedures for each loading event, with the exception of loading events performed at a negative pressure:

1.Obtain a copy of the record of the most recent pressure test or leak test on the receiving marine vessel. The record must contain all information specified in § 32.8(B) of this Part.

2.If, according to the records obtained pursuant to the requirements of § 32.7(C)(1) of this Part, the marine vessel passed the most recent pressure or leak test and that test was performed within the previous 12 month period, the vessel shall be considered vapor tight.

3.If, according to the records obtained pursuant to the requirements of § 32.7(C)(1) of this Part, the marine vessel failed its most recent leak or pressure test, no loading event shall be conducted unless the operator of the marine vessel provides written documentation that all leaks have been repaired subsequent to the failed test. Any loading event involving a marine vessel that has been repaired subsequent to failing its most recent leak or pressure test must be conducted in conjunction with the performance of a leak test, as specified in § 32.7(C)(4) of this Part.

4.If, according to the records obtained pursuant to the requirements of § 32.7(C)(1) of this Part, the marine vessel has not passed a leak or pressure test within the previous 12 month period, a leak test of the vessel shall be performed during the loading event. No loading events shall be performed if the vessel failed its most recent leak test or pressure test and does not provide the owner or operator of the marine terminal with documentation that shows that all leaks subsequently have been repaired, as specified in § 32.7(C)(3) of this Part.

5.A person testing a marine vessel to determine whether that vessel is vapor tight shall provide the operator of the marine vessel and the owner or operator of the marine terminal with documentation of the test which includes all information specified in § 32.8(B) of this Part.

A.The owner or operator of a marine terminal loading facility shall record the following information about each loading event and maintain this information at the facility for a period of five years:

1.The location of the loading event,

2.The company responsible for conducting the loading event,

3.The date and time at which the marine vessel arrived and departed from the location of the loading event,

4.The name, registry of vessels and name and address of the legal owner of the marine tank vessel participating in the loading event,

5.The prior cargo carried by the receiving marine tank vessel,

6.The type and amount of liquid cargo loaded into the receiving marine tank vessel,

7.The condition of the receiving tanks prior to being loaded (i.e. cleaned, crude oil, washed, gas freed, etc.),
