WAC 173-182-365   Transmission pipelines and pipeline tank farms.  (1) To determine the amount of boom necessary for the two hour standard the plan holder must identify by WRIA, surface waters of the state with the potential to be impacted by a spill from the pipeline.

     (a) To determine the two-hour booming requirements, select the widest river within the WRIA.

     (b) Determine the average river speed at this location.

     (i) For rivers with a current of two knots boom in the amount of three times the widest point in the river that the pipeline could affect.

     (ii) For rivers with a current of three knots the requirement would be for five times the widest point in the river that the pipeline could affect.

     (iii) For rivers with a current of five knots the requirement would be for seven times the widest point in the river that the pipeline could affect.

     (2) Or alternatively, the two hour standard will be two thousand feet of boom.

     (3) Boom required for the two hour standard shall be dedicated to spill response and should be staged in various locations along the pipeline.


Time (hours) Boom/Assessment Minimum Oil Recovery Rate

% of WCS volume per 24 hours
Minimum Storage in Barrels
1 A safety assessment of the spill by trained crew and appropriate air monitoring could have arrived
2 Boom available at the spill source or downstream of the source could have arrived
6 Additional 5,000 feet of boom available for containment, recovery or protection could have arrived Capacity to recover the lesser of 10% of worst case spill volume or 12,500 barrels within 24-hour period could have arrived 1 times the EDRC
12 Additional 20,000 feet of boom to be used for containment, protection or recovery could have arrived Capacity to recover the lesser of 15% of worst case spill volume or 36,000 barrels within 24-hour period could have arrived 2 times the EDRC
24 More boom as necessary for containment, recovery or protection Capacity to recover the lesser of 20% of worst case spill volume or 48,000 barrels within 24-hour period could have arrived 3 times the EDRC
48 More boom as necessary for containment, recovery or protection Capacity to recover the lesser of 25% of worst case spill volume or 60,000 barrels within 24-hour period could have arrived More as necessary to not slow the response
