Narrative
The hidalgo plant, which delivers to the dcp hidalgo meter station, started their ngl pumps but brought them on too fast. This created an abnormally high operating condition that should have tripped mov-100 (esd valve) to close on the inlet to our hidalgo ngl meter station. The mov-100 valve failed to close when it received a high pressure shutdown of 1285 psig due to a hydraulic needle valve that was shut and/or a bad solenoid valve. Mitigative actions include retesting, rebuilding and reinstalling psv 200; replacing the solenoid valve and tighten the packing gland on the valve stem of the hydraulic needle valve
