Richland residents may hear controlled detonations today

Richland Energy Services plans to upgrade an electrical substation off Robertson Drive and Highway 240, and residents this week might hear controlled detonations about as loud as a shotgun or large firework in the immediate area as a result.

The upgrade involves reworking some high-voltage transmission lines, making a better connection, extending their operational life and improving reliability, the release said.

Three splices will be installed at once; the controlled detonations are set for late this morning but could happen later in the week if needed, the release said.
