Controlled detonations are going to be going off in Richland  part of an upgrade of an electrical substation. The substation is located off Robertson Drive and Hwy 240 so if you live in the vicinity of that area you may hear what sounds like bombs going off. The detonations may continue throughout the the week as Richland energy services upgrades an electrical substation. The upgrade is needed to improve connections and improve reliability of the lines.
