RULE 1142. MARINE TANK VESSEL OPERATIONS

(a) Applicability This rule shall apply to all loading, lightering, ballasting, and housekeeping events
where a marine tank vessel is filled with an organic liquid; or where a liquid is placed into a marine tank vessel's cargo tanks which had previously held organic liquid.

(b) Definitions (1) BACKGROUND is the ambient concentration of volatile organic compounds in the air determined at least one (1) meter upwind of the component being inspected. (2) BALLASTING is the loading of wate r or other liquid into a marine tank vessel's cargo tank to obtain proper propeller, rudder, and hull immersion. (3) SOUTH COAST WATERS means the Pacific Ocean area beginning at the
intersection of the Paci fic Ocean and the Los Angeles-Ventura County boundary; and proceeding southwesterl y to the intersection of the boundary of the California Coastal Waters at a point having the
coordinates of 33 o North Latitude and 119.5 o West Longitude; then southeasterly along said boundary of th e California Coastal Waters to a point having the coordinates of 32.5 o North Latitude and 118.5 o West Longitude; and then north easterly to the intersection of the Pacific Ocean and the Orange-San Diego County boundary. (4) EMISSION CONTROL EQUIPMENT m eans any equipment, machinery, apparatus, or device used to collect, store, or reduce the emissions of volatile organic compounds in the atmosphere. (5) EXEMPT COMPOUNDS are any of the following compounds that have
been determined to be non-precursors of ozone: (A) Group I chlorodifluoromethane (HCFC-22) dichlorotrifluoroe thane (HCFC-123) tetrafluoroethane (HFC-134a) dichlorofluoroethane (HCFC-141b) chlorodifluoroethane (HCFC-142b)Rule 1142 (Cont.) (Adopted July 19, 1991)

1142-2 (B) Group II methylene chloride 1,1,1-trichloroethane (m ethyl chloroform) trifluoromethane (FC-23) trichlorotrifluoroe thane (CFC-113) dichlorodifluoromethane (CFC-12) trichlorofluoromethane (CFC-11) dichlorotetrafluoroethane (CFC-114) chloropentafluoroethane (CFC-115) In the future, the use of Group II compounds may be regulated by the District because they are toxic or potentially toxic, upper atmospheric ozone depleters, or cause other enviro nmental impacts. The District Board has adopted a policy which states that chlorofluorocarbons (CFC) will be phased out at the earliest pract icable date on or before 1997. (6) GASEOUS LEAK means a condition th at exists when the reading on a portable hydrocarbon meter, measured 1 centimeter or less from any source, exceeds 1,000 parts per milli on, expressed as methane, above background. (7) HOUSEKEEPING consists of alteri ng the composition of gases contained within marine vessel tanks by tank washing, gas freeing, or purging. (8) LIQUID LEAK means a leak of mo re than three drops per minute of organic liquid. (9) LIGHTERING is the transfer of or ganic liquid into a cargo tank from one
marine tank vessel to another. (10) LOADING EVENT means an incide nt or occurrence beginning with the connecting of marine terminal storag e tanks or a marine tank vessel to marine tank vessel cargo tank(s) w ith pipes or hoses followed by the transfer of liquid cargo a nd ending with the disconn ecting of the pipes or hoses; or any other means of placing liquid into cargo ta nks. In addition, emissions resulting from the venti ng of volatile orga nic compounds in South Coast Waters prior to, during, or after a loading event are included in that loading event. (11) MARINE TANK VESSEL mean s any tugboat, tanker, freighter, passenger ship, barge, boat, ship, or watercraft, which is specifically
constructed or converted to carry liquid cargo in tanks.Rule 1142 (Cont.) (Adopted July 19, 1991)

1142-3 (12) MARINE TERMINAL means any f acility, equipment, or structure constructed to handle the loading or unl oading of organic liquid into or out
of marine tank vessels. (13) ORGANIC LIQUID means gasoline, gasoline blending stocks, aviation gas and aviation fuel (JP-4 type), cr ude oil and other liquids containing volatile organic compounds. (14) VOLATILE ORGANIC COMPOUND means any chemical compound which contains the element carbon, except methane, carbon monoxide, carbon dioxide, carbonic acid, metallic carbides or carbonates, ammonium carbonate, and exempt compounds.

(c) Requirements (1) Marine Tank Vessels (A) Effective January 1, 1992, an ow ner or operator of a marine tank vessel equipped with emission c ontrol equipment shall operate such equipment while conducting a loading, lighteri ng, ballasting, or housekeeping event in South Coast Waters. (B) Effective January 1, 1994 a loading, lightering, ballasting, or housekeeping event shall not be co nducted while in South Coast Waters, unless: (i) The emissions of volatil e organic compounds are limited to 5.7 grams per cubic meter (2 lb s per 1,000 barrels) of liquid loaded into a marine tank vessel; or (ii) The emissions of volatile organic compounds are reduced by at least 95 percent by weight from uncontrolled
conditions. (2) Liquid and Gaseous Leaks Effective January 1, 1994, all hatches, pressure relief valves, connections, gauging ports and vents, and other equipment associated with a loading, lightering, ballasting, or housekeeping ev ent shall be maintained free of liquid or gaseous leaks. Any liquid or gaseous leak shal l be tagged upon detection and repaired within 4 hour s of detection by the owner or operator. Any liquid or gaseous leak detected by District staff shall
constitute a violati on of this rule.Rule 1142 (Cont.) (Adopted July 19, 1991)

1142-4 (3) Emission Control Equipment The emission control equipment shall be designed and operated to collect, store, and process all emissions of volatile organic compounds resulting from a loading, lightering, balla sting, or housekeeping event.

(d) Compliance Schedule Any owner or operator of a marine tank vessel or a terminal shall submit to the District Executive Officer an applica tion for a Permit to Construct by April 1, 1992, for any equipment required to comply with the provisions of this rule.
