Discrepancies:
• The inlet valve at Regulator Station 3760 was not listed in Maximo, no annual inspection data.
• Soil erosion has occurred around Regulator Station 369. Recommend adding topsoil and/or gravel
to restore proper grade and prevent further washout.
• The pipe-to-soil interface at HPSS 3089 was damaged, exposing bare steel. The regulator
technician removed the damaged wrap and painted the exposed steel on-site. Wax wrap was
applied the following day.
