Narrative
At approximately 20:10 on april 27, 2020, magellan operations personnel identified an area of stained soil within the east houston terminal. The area was excavated and a below grade 1' drain line check valve was found to have a cracked body and was leaking product. The line was isolated and cleanup activities of the impacted soil were initiated. A new check valve was installed prior to returning the isolated drain line back to service. Metallurgical analysis of the check valve indicates that the failure was due to ductile overload of the material caused by a bending moment. Supplemental/final (09/02/2020): updated g6 and h.
