Narrative
On july 2, 2012 a release of 2.4 barrels of refined petroleum product was identified from a 2 inch unit suction refill line for unit #1 at the houston pump station. The free phase product was removed by vacuum truck and any petroleum impacted soil was tested and properly managed. The line was removed and blinded off at both ends. The metallurgical failure analysis indicated internal pitting corrosion located at the bottom side of an elbow caused by the presence of inorganic salts and sulfur in the corrosion pit. The metallurgical analysis also indicated there was no evidence of microbial induced corrosion.
