Over-Water Oil Transfer Operations in Washington State

Friends of the San Juans

Washington State requires advance notice of over-water oil transfer operations to help prepare for and prevent oil spills. The advance notice of transfer data is maintained by the Department of Ecology in a spreadsheet and available to the public via a public records request. An interactive Microsoft Power BI tool was created by Exa to make this data easier for the public to learn about and explore. Friends of the San Juans uses this visualization tool to increase community engagement and advocacy for stronger environmental protections in rulemakings and other regulatory updates. Data are presented in an explorable map with result values proportional to the total volume of oil transferred. Data can be filtered by transfer type, transfer rate and type of product. Values also indicate the proportion of oil transfers with oil spill mitigation measures deployed. https://sanjuans.org/oil-transfer-data/
