During the Ecology plan review period we apply a conceptual model to evaluate if oil spill plans have access to the required response equipment and personnel to respond to a worst case spill as defined in their contingency plan.  This process is described in the rule at: WAC 173-182-350 Documenting compliance with the planning standards, and WAC 173-182-610 Plan evaluation criteria. The model is used to develop a planning standard spreadsheet which becomes part of the plan. Each oil spill scenario is unique but a conceptual model allows Ecology to examine questions about capability and reach conclusions within an idealized framework.  Review the document “Evaluating Contingency Plan Holder Planning Standards” for additional detail on the conceptual model.

Washington rules establish planning standards in these areas:

173-182-355 Transfer sites for covered vessels at locations where transfers occur, and for facilities with a vessel terminal
173-182-365 Transmission pipelines and pipeline tank farms
173-182-370 San Juan County planning standard
173-182-375 Padilla Bay planning standard
173-182-380 Commencement Bay Quartermaster Harbor planning standard
173-182-385 Nisqually planning standard
173-182-390 Dungeness planning standard
173-182-395 Neah Bay staging area
173-182-400 Copalis, Flattery Rocks and Quillayute Needles planning standard
173-182-405 Grays Harbor planning standard
173-182-410 Willapa planning standard
173-182-415 Cathlamet staging area
173-182-420 Vancouver planning standard
173-182-430 Tri-cities planning standard
173-182-450 Planning standards for the Washington coast


Here is how it works:

Ecology develops the first draft of the spreadsheets based on where a plan holder operates or transits. All response equipment used to populate the spreadsheets is listed by Plan Holders and Primary Response Contractors on the Western Regional Resource List (WRRL). See our presentation for additional detail of the GIS tool used to execute the model and how to interpret the planning standard spreadsheets.

The spreadsheets are given to the plan holder for review. It is the plan holder’s responsibility to take the following steps in order to be in compliance with the planning standard spreadsheet requirement:

  • Review the spreadsheet and understand the content.
  • Set up a meeting with Ecology if there are any questions.
  • Ensure that the summary page of the spreadsheet is included in the plan and that references to where the spreadsheets can be found are included in the Table of Contents for the plan and the WAC 173-182 regulatory cross reference.
  • Include a short narrative in the plan that describes which planning standards are applicable to your plan and refers to the planning standard spreadsheet(s) as a demonstration of how the planning standards will be met.  Include a link to the FTP site where Ecology maintains the rest of the spreadsheet documents, and where the most current spreadsheets can be found.
  • Use the spreadsheets to support response team understanding of the equipment available to the plan holder in drills and spills and the estimated the time for the equipment to arrive on scene.

If a plan holder has a proposed or actual change in WCD, response contractor, or operating area they may request updated planning standard spreadsheets from their Ecology Plan Compliance Specialist.

All contingency plan holder spreadsheets for approved plans are available for review at anytime at the Spills Program
FTP site.
