The
most recent oil spill in California highlights both fundamental
weaknesses in basic safeguards for our nation's oil infrastructure as
well as risks associated with industry plans to expand tar sands infrastructure in the West Coast.
On May 19, a pipeline owned by Plains All American ruptured, soiling more than 4 miles of California's coast and marine waters
with 21,000 gallons of crude oil. This isn't the first time in recent
memory that California has been subject to a major spill from PAA's
pipeline system - in May 2014 the company's West Coast pipeline spilled more than 10,000 gallons into the streets of Los Angeles.
This
spill in Santa Barbara uncovers the gap between industry's rhetoric and
reality, revealing risks associated with oil transportation
infrastructure, the poor record of leak detection technology, and the
inadequacy of spill response. Moreover, this incident demonstrates the
real risks associated with industry plans to inundate California's coastal waters, pipelines, rail lines and refineries with tar sands crudes.
The
11-mile Plains American Coastal Pipeline connects Exxon's Las Flores
Canyon facility - which provides basic processing for crude produced
from California's Outer Continental Shelf (OCS) - to Plain's larger Line
63 pipeline system.
- Leak detection. Once again, the pipeline operator's leak detection system appears to have missed this spill, as a member of the public called in the spill around noon after smelling the petroleum fumes. This again highlights the sad secret when it comes to the state of pipeline leak detection - systems miss 19 out of 20 spills. Perhaps most surprisingly, leak detection systems miss 4 out of 5 spills larger than 40,000 gallons. Federal regulators at the Pipeline and Hazardous Materials Safety Administration (PHMSA) are aware of the problem - they published a report in late 2012 highlighting failures in both industry practices, technical and federal regulations in detail - but little has been done to address it. Even so, industry often touts its technology and many in the public are under the impression that it is able to detect even the smallest leaks. That's simply not true.
- Spill response. While the public reported the spill at noon, the pipeline was not shut down until around 3 p.m., according to the Los Angeles Times. Meanwhile, the ruptured pipeline was sending crude oil into the Pacific Ocean. While this delay is certainly unacceptable, it is not unprecedented. When Enbridge's pipeline spilled 830,000 gallons of tar sands into Michigan's Kalamazoo River, it took the company 12 hours to shut the pipeline down.
- Clean-up efforts. Unfortunately, little progress has been made in terms of spill response measures and technology - the tools available to spill responders today haven't changed for decades. Weaknesses in marine oil spill response plans and techniques occur against a backdrop of proposals to increase crude oil produced from and moved through ocean waters. This problem will only be compounded as industry works to increase the transport of tar sands oil in marine waterways - as tar sands bitumen is heavier than water, evading conventional spill response measures that rely on oil to float. Five years after a tar sands spill in Michigan confounded spill responders - after more than $1 billion in clean-up activities, nearly 40 miles of the river is still contaminated - no improvements have been made in tar sands spill response measures.
This pipeline
accident and marine oil spill only highlights the threat of industry's
plans to dramatically increase the volumes of tar sands destined for
California. As NRDC detailed in a report released last month,
the tar sands industry is seeking to increase tar sands shipments into
California from 50,0000 barrels per day (bpd) to more than 650,000 bpd.
This tar sands crude would finds its way to California's refineries
using both new and existing transportation infrastructure - including
the Plains All American pipeline system.
- Threats to California's marine waters. The report highlights plans by the tar sands industry to increase tanker and barge traffic 25-fold, from 80 to more than 2,000 vessels, moving along the Pacific west coast. A large portion of these will be headed to California, putting California's coastal waters at risks from tar sands spills due to barge or tanker accidents. Tar sands oil spills pose an even greater challenge to clean-up efforts, particularly in water bodies.
- Threats to California's pipelines. Much of this tar sands would be transported to California's refineries via pipelines like Plains All American Line 63 , which ships crude both from offshore sources and California's interior to the state's refineries. Moreover, Plains is increasingly integrating its pipeline system to handle crude by rail. While this is currently primarily light crude, like many industry participants, Plains All American is anticipating increasing volumes of heavy tar sands moving onto its system in the future.
The
tragic oil spill into California's coastal waters is yet another
example of the many costs of our current dependence on crude oil. There
is a better path forward. We need stronger safeguard to ensure the
safety of our existing infrastructure. We also need to pursue policies
to reduce oil consumption, prevent the expansion of hig- carbon and
environmentally damaging sources of oil like tar sands and spur
low-carbon transportation such as electric vehicles. Through both
opposition to tar sands infrastructure and support for regional clean
energy policies, we can prevent the influx of tar sands crude and build
the green infrastructure and public support necessary to begin
transitioning to a clean energy economy.
