Pre-Spill SCAT Project Brief Oct, 2013
SCAT (Shoreline Cleanup Assessment Technique) is a procedure and process, now used
worldwide, legally enshrined in the USA, very strongly supported in Canada by federal and
provincial agencies. In the field, SCAT teams
systematically survey the area affected by the spill
using standardized methods and terminology to provide accurate consistent real time
documentation of shoreline conditions. In addition they document operational features,
backshore staging conditions, access, and operational or safety constraints. The teams can
identify or verify environmental, cultural, recreational, economic features and constraints, or
may provide recommendations regarding appropriate treatment techniques or cleanup
endpoints. The same teams may conduct post treatment SCAT surveys to determine if the
endpoint criteria have been attained. The individual field data are put into a specialized data
base/ GIS system, analyzed and used in a wide range of applications. The data and information
generated by the SCAT surveys are crucial to the decision process and are the basis of spill
planning for the operational stages of the shoreline response.
Although some of the information, e.g. oiling conditions, must be collected real time, a large
amount of directly relevant information can be assembled pre-spill and a spill ready database of
knowledge critical to the SCAT process and shoreline response decision making can be prepared
in advance in the form and quality that would be needed in the event of a spill. In fact it is more
sensible to collect/assess certain data during the pre-spill period when there is more time
available to address issues, rather than in the initial stressed emergency stage. By being
proactive and collecting such information in advance of any event, it is possible to enhance
preparedness planning, to ensure best practice guidance and process are in place and to
advance sound decisions from the very beginning of a response.
In general, the BC environmental information base as needed for SCAT, is many years out of
date, no longer providing accurate information, or is incomplete in terms of information needs
for "best practice" that has been developed for oil spill response.
As a result, Trans Mountain
Pipeline ULC (Trans Mountain) approved a project in May 2013 to develop an updated dataset
for Central Burrard Inlet, Vancouver Harbor in the vicinity of the Westridge Terminal. The foot
print, shown below, is bounded to the west by the second narrows bridge, to the east by Port
Moody, and north by the power line crossing north of Deep Cove. The shoreline of the area is
complex in nature and type with considerable manmade influence to shoreline geomorphology
and access.
