Location
TX
Narrative
When the release was discovered it did not appear that notification to the nrc would be required, however due to the location and logistics of transporting personnel and equipment to the site it was determined that the $50,000 criteria would be met. An nrc report was made at that time. Propane was bubbling through standing water in a low area, no sheen, emulsion or other visible water impact was observed during the release. [requested update 3/24/2020: release investigation determined it was seam weep from a penetrator-type lack of fusion at the seam (seam crack). This feature was repaired on november 7, 2013 by installation of a plidco clamp and recoating the pipe with type 2 wax tape.]
