given that the pipeline crosses 247 miles of the Ogallala Aquifer, or 14.5 % of the entire pipeline length , and 50 year life of the entire pipeline is expected to have between 11-91 spills, 1.6 - I3.2 spills can be expected to over the aquifer. An estimate of 13.2 spills over the aquifer,each lasting 14 days, reduced scope 'worst case exposure scenario, the volume of a pinhole leak at 1.5% of oil. According to PHMSA ' s incident database, only 0.5% of all spills in the last I0 years were >100000 barrels
