(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)) SWCAA, 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)) SWCAA 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)) SWCAA.
(iii) Gaseous leaks must be detected using EPA Method 21 or
other methods approved in writing by ((SWAPCA)) SWCAA.
(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)) SWCAA 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)) SWCAA 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)) SWCAA 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)) SWCAA declares a Clean Air Action (CAA) day. If
((SWAPCA)) SWCAA 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)) SWCAA
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.

((SWAPCA)) SWCAA 491-050 Failures, Certification, Testing and
Recordkeeping
[Statutory Authority: Chapter 70.94.141 RCW and 70.94.165 RCW. Original adoption WSR 93-16-011 filed 7/22/93, effective 8/22/93; WSR 96-21-102 filed 10/21/96, effective 11/21/96, WSR 00-11-149 filed 5/24/2000, effective 6/24/2000]
This section shall apply to all gasoline transport tanks
equipped for gasoline vapor collection and all vapor collection
systems at gasoline loading terminals, and bulk gasoline plants
as described in subsections (2) and (3) of ((SWAPCA)) SWCAA
491-040.
(1) Failures.
During the months of May, June, July, August, and September any failure of a vapor collection system at a bulk gasoline plant or gasoline loading terminal to comply with this section requires the immediate discontinuation of gasoline transfer operations for the failed part of the system. Other transfer points that can continue to operate in compliance may be used. The loading or unloading of the transport tank connected to the failed part of the vapor collection system may be completed during the other months of the year. Upon completion of loading or unloading of a transport tank connected at the time of the failure, gasoline transfer operations shall be discontinued for the failed part of the system.
(2) Certification.
(a) The owner or operator of a gasoline loading terminal or
bulk gasoline plant shall only allow the transfer of gasoline
