Narrative
On 1/8/2022, dewv personnel were monitoring system pressures because of cold weather. In the course of doing this, they identified a pressure increase from 8 ounces to 10 ounces at 11:00 hours; and another increase from 10 ounces to 35 ounces at 12:00 hours. The pressure returned to 8 ounces at 13:00 hours, which is believed to be from an increase in temperature relieving moisture and ice from the regulators. During the event, a leak was discovered on a mainline. Three regulating stations that feed the system were shut in, creating an outage for 162 customers. The mainline leak was repaired, the system was leak surveyed with no additional hazardous leaks found, and safety checks and restoration of customers were initiated beginning on the morning of 1/9/2022.
