Current through Register Vol. 24-14, July 15, 2024
This section generally applies to delivering facilities;
				  however, any Class 1 facility receiving oil from a Rate A delivering vessel
				  must provide the facility's approved safe and effective threshold values to the
				  vessel.
(1) The Rate A deliverer must
				preboom oil transfers when it is safe and effective to do so. When prebooming
				is not safe and effective, the deliverer must meet the alternative measures
				requirements found in subsection (9) of this section and submit the
Ecology Boom Reporting Form
pursuant to subsection (4) of this
				section.
(2) The determination of
				safe and effective must be made prior to starting a transfer and reevaluated if
				conditions change before or during a transfer. To make this determination, the
				deliverer must use the safe and effective threshold values found in their
				operations manual. The safe and effective determination must be based on the
				conditions at the transfer location.
(3) When water currents are 1 knot or less,
				facilities must consider prebooming if it is safe to do so, even if the boom
				may be less than fully effective. When water currents are greater than 1 knot,
				facilities may consider prebooming based on the expected performance of the
				boom.
(4) When it is not safe and
				effective to preboom, or when conditions develop during a preboomed transfer
				that require removal of the boom, the Rate A deliverer must report this finding
				to ecology through the
Ecology Boom Reporting Form
. The form
				must include all observed and forecasted conditions that exceed the weather and
				safety values in the safe and effective threshold determination report. The
				form must be submitted on ecology's website or by email. Form number ECY
				070-215 must be used. The form must be submitted prior to the transfer and/or
				immediately when conditions have changed.
(5) If a transfer is not preboomed due to
				conditions exceeding the safe and effective values, or if the boom is removed
				due to changing environmental conditions during the transfer, the Rate A
				deliverer must boom the transfer if it becomes safe and effective to do so. If
				environmental conditions continue to exceed safe and effective values,
				follow-up
Ecology Boom Reporting Forms
must be submitted every
				six hours for a transfer at a terminal.
(6) If multiple oil transfers are occurring
				simultaneously with a single vessel, and one product transferred is not
				appropriate to pre-boom, such as gasoline, aviation gasoline, ethanol, nonene,
				and other highly volatile products with similar characteristics, then that
				portion of the transfer where it is not appropriate to preboom must meet the
				alternative measures found in subsection (9) of this section. The portion of
				the transfer that is appropriate to preboom must be preboomed if:
(a) It is safe and effective to do
				so;
(b) Pumping is complete for the
				product that is not appropriate to preboom; and
(c) There are at least three hours remaining
				in the transfer.
