As part of its Habitat Conservation Plan (HCP), the Pacific Lumber Company is evaluating the
effects of its management activities on the water quality parameters of streams within its 225,000-acre
ownership. During the development of the HCP it was recognized that sediment generated from road
sources (e.g., crossing failures, surface erosion) was in large enough quantities to be deleterious to aquatic
habitat, a conclusion supported by subsequent watershed studies. These sediment sources contribute to
exceedences of TMDLs in areas so analyzed, and will likely be important in future, planned TMDL
evaluations. To address these issues, the Pacific Lumber Company has instituted the interim road
management plan contained in the HCP for its 1500 miles of permanent and seasonal roads.
