The following information was provided by the Agency via email: On May 6, 2023, the Agency received a phone call from the licensee's service provider who reported that yesterday (May 5, 2023) Shell Chemical LP in Deer Park, Texas, had a fire and explosion. On May 10, 2023, the Agency was notified by the licensee's service provider (SP) that the licensee was able to use a drone to inspect the area of the fire. The SP stated that they were able to see one of the gauges which was still located in the same position it was in before the fire. The second gauge could not be located due to all the debris in the area. The SP stated the gauges original position was on a pipe six feet above the ground. They believe the pipe may have fallen to the ground and the gauge went with it. The SP stated the licensee did perform a radiation survey outside the exclusion area in the area where the gauges are located, and the readings were background. The SP did not know how close they would have been to the gauges. The licensee is making plans to enter the area, but the weather is causing delays as they have to shut down outside activities anytime there is lightning within 10 miles of the plant. The SP stated they did not have a date or time when they will be able to access the gauges. The SP stated they have discussed how they will conduct contamination surveys and radiation surveys once they gain access to the area.
