(6) Loading or Unloading Gasoline into Marine Tank Vessels
(a) Applicability. This rule applies to loading events at any location within the Vancouver ozone air quality maintenance area when gasoline is placed into a marine tank vessel cargo tank; or when any liquid is placed into a marine tank vessel cargo tank that had previously held gasoline. The owner or operator of each marine terminal and marine tank vessel is responsible for and must comply with this rule. All facilities shall be in compliance no later than June 1, 2001.
(b) Exemptions. The following activities are exempt from the marine vapor control emission limits of this rule:
(i) Marine vessel bunkering (refueling);
(ii) Lightering when neither vessel is berthed at a marine terminal dock,
(iii) Loading when both of the following conditions are met:
The vessel has been gas freed (regardless of the prior cargo), and
When loading any products other than gasoline.
(c) Vapor Collection System. The owner or operator of a marine terminal subject to this rule must equip each loading berth with a vapor collection system that is designed to collect all displaced VOC vapors during the loading of marine tank vessels. The owner or operator of a marine tank vessel subject to this rule must equip each marine tank vessel with a vapor collection system that is designed to collect all displaced VOC vapors during the loading of marine tank vessels. The collection system must be designed such that all displaced VOC vapors collected during any loading event are vented only to the control device.
(d) Marine Vapor Control Emission Limits. Vapors that are displaced and collected during marine tank vessel loading events must meet one of the following:
(i) Vapors must be reduced from the uncontrolled condition by at least 95 percent by weight, as determined by EPA Method 25 or other methods approved in writing by SWAPCA, or
(ii) Vapor emissions shall not exceed 5.7 grams per cubic meter (2 pounds per 1000 barrels) of liquid loaded.
(e) Operating Practice and Maintenance.
(i) All hatches, pressure relief valves, connections, gauging ports and vents associated with the loading of fuel product into marine tank vessels must be maintained to be leak free and vapor tight.
(ii) The owner or operator of any marine tank vessel must certify to SWAPCA that the vessel is leak free, vapor tight, and in good working order based on an annual inspection using EPA Method 21 or other methods approved in writing by SWAPCA.
(iii) Gaseous leaks must be detected using EPA Method 21 or other methods approved in writing by SWAPCA.
(iv) Loading must cease anytime gas or liquid leaks are detected. Loading may continue only after leaks are repaired or if documentation is provided to SWAPCA that the repair of leaking components is technically infeasible without dry-docking the vessel or cannot otherwise be undertaken safely. Subsequent loading events involving the leaking components are prohibited until the leak is repaired. Any liquid or gaseous leak detected by SWAPCA staff is a violation of this rule.
(f) Monitoring and Record-Keeping.
Marine terminal operators must maintain operating records for at least five years of each loading event at their terminal. Marine tank vessel owners and operators are responsible for maintaining operating records for at least five years for all loading events involving each of their vessels. Records must be made available to SWAPCA upon request. These records must include but are not limited to:
(i) The location of each loading event.
(ii) The date of arrival and departure of the vessel.
(iii) The name, registry and legal owner of each marine tank vessel participating in the loading event.
(iv) The type and amount of fuel product loaded into the marine tank vessel.
(v) The prior cargo carried by the marine tank vessel. If the marine tank vessel has been gas freed, then the prior cargo can be recorded as gas freed.
(vi) The description of any gaseous or liquid leak, date and time of leak detection, leak repair action taken and screening level after completion of the leak repair.
(g) Lightering exempted from controls by subsection 6(b) of this rule must be curtailed from 2:00 AM until 2:00 PM when SWAPCA declares a Clean Air Action (CAA) day. If SWAPCA declares a second CAA day before 2:00 PM of the first curtailment period, then such uncontrolled lightering must be curtailed for an additional 24 hours until 2:00 PM on the second day. If a third CAA day in a row is declared, then uncontrolled lightering is permissible for a 12 hour period starting at 2 PM on the second CAA day and ending at 2 AM on the third CAA day. Uncontrolled lightering must be curtailed from 2 AM until 2 PM on the third CAA day. If SWAPCA continues to declare CAA days consecutively after the third day, the curtailment and loading pattern used for the third CAA day will apply.
(h) Safety/Emergency Operations. Nothing in this rule is intended to:
(i) Require any act or omission that would be in violation of any regulation or other requirement of the United States Coast Guard; or
(ii) Prevent any act that is necessary to secure the safety of a vessel or the safety of passengers or crew.
AMENDATORY SECTION
