Today Chris Blondeau,. and Courtney Edwards  took Martin Haulena , and Joe Gaydos to Race Rocks to meet with Ecoguardian Anne Stewart and take stock of the facility and make plans for how to deal with the plastic neck bands  that we have are observing with the onset of the large numbers of sealions each year.

Material Safety Data Sheet for Dilbit or Diluted Bitumin

If you click on the category “Oil Spill Risk” you may  have some appreciation for the potential hazards we face at Race Rocks in the event of a Oil Spill involving Dilbit which is already being shipped in some tankers through the Strait of Juan de Fuca within 4 miles of the Race Rocks Ecological Reserve, but if the Kinder Morgan Pipeline Expansion project is approved by the Canadian Government will be the contents of up to 35 tankers per month.

From the National Energy Board we can find out what is in Dilbit and what precautions we need when it lands on the shores of Race Rocks.

Pelicans again at Race Rocks

Thanks to Rick Page, a Board Member of Friends of Ecological Reserves for forwarding  these images of Brown Pelicans taken at Race Rocks today. He says ” I was in the bow of the boat and noticed the profile of the pelicans from a long way out as they stood on the peak of West Rocks.”
