Although the
Pipeline and Hazardous Materials Safety Administration (PHMSA) has standard baseline incident frequencies to estimate the number of spills, TransCanada altered these assumptions based on improved pipeline design, operation, and safety.[SUP]
[43][/SUP] Whether these adjustments are justified is debatable as these assumptions resulted in a nearly 10-fold decrease in spill estimates.[SUP]
[42][/SUP] Given that the pipeline crosses 247 miles of the Ogallala Aquifer,[SUP]
[44][/SUP] or 14.5% of the entire pipeline length, and the 50-year life of the entire pipeline is expected to have between 11 – 91 spills,[SUP]
[42][/SUP] approximately 1.6 – 13.2 spills can be expected to occur over the aquifer. An estimate of 13.2 spills over the aquifer, each lasting 14 days, results in 184 days of potential exposure over the 50 year lifetime of the pipeline. In the reduced scope ‘worst case exposure scenario,’ the volume of
a pinhole leak at 1.5% of max flow-rate for 14 days has been estimated at 189,000 barrels or 7.9 million gallons of oil.[SUP]
[42][/SUP] According to PHMSA’s incident database,[SUP]
[45][/SUP] only 0.5% of all spills in the last 10 years were >10,000 barrels.

The tree huggers will be dozed under, climate change will not be funded by tax payer dollars, no more tax credits for over priced under producing green energy firms....game over. There's a new day dawning in the United States of America because the left could not steal this last election.
