Narrative
On 4/8/2015 at 13:00 an enterprise employee noticed an iceball on the ground at the location of a 2" riser at enterprise's mont belvieu facility. The pipeline corridor has several lines, some of which are plant piping. The line was shut down on 4/8/2015 at 16:58 to determine if it was the mont belvieu meter site to enterprise eol line. The line was blown down to 0 psi and then nitrogen was introduced. Nitrogen was found to be present at the 2" riser, giving confirmation that the mont belvieu meter site to enterprise eol line was the one leaking. The line was excavated and a pinhole leak was found on the 2" piping. The pipe with the leak was cut out and was replaced. The line was put back in service on 4/12/2015 at 02:30. At 14:28 on 4/11/2015 the nrc was called after the repair cost was determined to be greater than $50,000 dollars.
