Narrative
On july 22, 2013, the dow chemical company officially reported a leak on a pygas pipeline, dpl-191. The national response center report number for this incident is 1054720 and the railroad commission of texas incident number is 825. Low pressure hydrotesting the line confirmed that the pipeline had a pinhole leak in a girth weld. Metallurgical analysis from cut-outs taken of the line indicated that brine water constituents from the pygas storage well were a probable cause of the internal corrosion in the locally affected zone closest to the storage well (area where pinhole leak was found). Once the leak was discovered, the line was shut down, cleaned and cleared. Currently, dow is assessing the pipeline for any further corrosion or issues. The surrounding area has been properly remediated and all product has been recovered. On 1/19/2015 - updated the smys. Was incorrectly entered as %smys.
