(Portland, OR) -- The U.S. Forest Service has approved using heavy equipment and fire retardant in forested areas where there aren't any roads. Use of the equipment will be approved on a case-by-case basis. The equipment can be used when it's needed to protect lives, property, and valuable natural resources like old growth forests. Heavy equipment includes bulldozers, that can be used to reopen closed roads that can become containment lines. The Willamette National Forest in the area of the Pyramid Fire is getting the first approval.
