During Rate A transfers, the rules require that facility owners or operators must determine the “threshold values” beyond which they believe pre-booming may be unsafe or ineffective. Such factors may include:
Facilities must submit a Safe and Effective Threshold Determination Report to Ecology for review and approval for each location at which the delivering vessel plans to conduct Rate A transfers.
This report contains the environmental threshold values for determining when it is safe and effective to pre-boom; it also may contain the environmental threshold values for shutting down the transfer operation.
The report is a detailed analysis based on environmental data collected on the site and the boom manufacturer’s recommendations for effectiveness. The delivering vessel operator must also take into account the safety of the personnel involved in the possible pre-booming deployment.
Report requirements may be found in WAC 173-180-224.
New! Additional guidance on how to prepare reports (including checklists) was prepared for Ecology by Polaris Applied Sciences, Inc. Click here to download a pdf that (1) describes the proposed Safe and Effective Threshold Determination report review process and (2) provides corresponding checklists (Revised 6/14/2007).
These reports must be submitted to Ecology within 180 days from the effective date of the rule. Due to delays in releasing our in-depth guidance document for this requirement, Ecology has extended this date to June 1, 2007.
Ecology will make the report available for a thirty calendar day public review and comment period. The S & E reports available for public review can be found here.
The reports can be viewed at Ecology’s headquarters (see MAP). Please contact us ahead of time to schedule the review.
