Number 2 Prefrac Bottoms Stream Line to TK61
Cause: number 2 prefrac bottoms stream line to TK61 was leaking due to a hole in the pipe. Maphtha migrated across sOil and accumulated in an onsite concrete drain pipe.

Followup: No

Notes: Line was isolated and released material was contained within refinery property and recovered for proper handling. Excavated sOils were containerized and stored on site. Put in place a piping inspecion program to routinely assess and inspect pipes in order to reduce the likelihood of an incident occurring due to the same root cause.

Cooling exchanger
Cause: There was a pinhole leak in a naphtha tube of the cooling exchanger.

Followup: No

Notes: At the time of the State Police Hazmat Line report, the refinery was preparing to shut the unit down and make repairs within 24 hours. There were no injuries, fires, fatalities, or road closures.

Tank 61
Cause: Personnel observed a material leaking at Tank 61 from the roof drain area in the dike area. Upon identification, personnel mobilized and safely blocked in the roof drain and dike valve in the containment area. Due to heavy rains the roof drain and dike valve were open for draining the area per normal work practice. CRLLC personnel noticed some hydrocarbon had entered the concrete drain ditch, where it was contained. While blocking in the roof drain, personnel noted that hydrocarbons and water partially covered the north side of the tank roof. The tank immediately began to be pumped down to empty the contents. The tank was pumped down to a level that completely exposed the tank roof. After identification of the issue, the area was foamed to minimize emissions, and cleanup began immediately. CRLLC is conducting a failure analysis of the tank roof to determine the cause of the failure.

Followup: Yes

Notes: After isolating the leak, operators used foam to minimize volatilization and vacuum trucks were utilized to clean up the area. All material in Tank 61 was transferred to Tank 60 to allow operators to address the Tank 61 floating roof.
