Project Description

Following the conclusion of the Butte Fire response in 2016, Pacific Gas & Electric (PG&E) designed an Expanded Debris Management (EDM) program to remove and process vegetative material surrounding their power lines. The EDM program responds to the tree mortality dilemma by targeting vegetative material left from felling operations specific to PG&E’s 2nd Patrol. The program covers approximately 70,000 line miles and spans a geographic area consisting of twelve counties across California. Approximately 400 project workers are presently connected to the EDM program, which is initiated immediately after tree felling operations.

 

The goal of the EDM program is the removal of all hazardous trees from private property within deemed proximity of a structure or PG&E assets. EDM crews lawfully enter the private property and remove dead & dying trees as identified by PG&E. All material collected from EDM operations is taken to the appropriate temporary Debris Management Site (DMS) for processing (reduction) or preparation for transportation to a timber mill or a biomass facility for beneficial reuse.

P&J’s Contribution

P&J provided over 110 crews to remove over 25k hazardous trees during the 2016 Butte Fire response, and PG&E continued this relationship into the CEMA EDM program. After the material is delivered to a P&J DMS, the scope transitions to reducing or processing the material in preparation for final re-use. The material is unloaded and sorted, with resulting stockpiles consisting of either material to be reduced via mechanized grinding or whole length logs accepted as marketable timber. Marketable timber is prepared and loaded for transportation to the appropriate timber mill, with any resulting proceeds to be returned to PG&E in the form of a credit. All other material is reduced via grinding and delivered to the appropriate facility for reuse.

Of the tonnage that has been hauled to DMSs by EDM crews, the vast majority has been mechanically reduced, with the resulting chips hauled to cogeneration facilities around the state. Since May of 2017, much of the material has been hauled directly to cogeneration facilities, bypassing P&J DMS entirely. The cogeneration facilities, which include Sierra Pacific Industries and IHI Power plants, provide credits back to P&J for the material received. P&J, in turn, provides salvage proceeds to subcontract crews.

Approximately 400 project workers (including P&J and subcontractor employees) are presently engaged in the EDM Program, and over half of them are California residents. At peak, over 800 workers have supported the project simultaneously, amounting to more than 100 production and support crews.

To date, approximately 84,000 trees (greater than 250,000 tons of vegetative material) have been removed through the EDM program. In total, P&J has performed vegetation management services on more than 40,000 acres under the PG&E CEMA EDM program.
