Tar Sands Pipelines Safety Risks

Friday, February 18th, 2011

Tar sands crude oil pipeline companies may be putting America’s public safety at risk. Increasingly, pipelines transporting tar sands crude oil into the United States are carrying diluted bitumen or “DilBit”—a highly corrosive, acidic, and potentially unstable blend of thick raw bitumen and volatile natural gas liquid condensate—raising risks of spills and damage to communities along their paths.Currently, tar sands crude oil pipeline companies are using conventional pipeline technology to transport this DilBit. These pipelines, which require higher operating temperatures and pressures to move the thick material through a pipe, appear to pose new and significant risks of pipeline leaks or ruptures due to corrosion, as well as problems with leak detection and safety problems from the unstable mixture.

IN HARM’S WAY: Lack Of Federal Coal Ash Regulations Endangers Americans And Their Environment

Monday, August 30th, 2010

ENVIRONMENTAL INTEGRITY PROJECT
An investigation led by expert hydrogeologists has identified 39 more coal combustion waste (CCW) disposal sites in 21 states that have contaminated groundwater or surface water with toxic metals and other pollutants. Their analysis is based on monitoring data and other information available in state agency files and builds on a report released in February of 2010, which documented similar damage at 31 coal combustion waste dumpsites in 14 states. When added to the 67 damage cases that the U.S. Environmental Protection Agency (USEPA) has already acknowledged, the total number of sites polluted by coal ash or scrubber sludge comes to at least 137 in 34 states. This total represents nearly a three-fold increase in the number of damage cases identified in EPA’s 2000 Regulatory Determination on the Wastes from the Combustion of Fossil Fuels.
