The Eastside Sustainable Harvest Calculation (SHC) is a multi-year planning effort by the Washington State Department of Natural Resources (DNR) to determine how much timber can be sustainably harvested from forested state trust lands in eastern Washington over the next ten years. This calculation, required by state law (RCW 79.10.300–.340), helps DNR balance its legal trust obligations—such as generating revenue for schools and counties—with forest health, wildlife habitat, carbon storage, and other public values. The SHC is a non-project agency action, meaning it does not directly authorize any on-the-ground activity. Instead, it sets harvest volume targets that guide future timber sales during the upcoming planning decade. Each timber sale will still go through its own, site-specific environmental review under the State Environmental Policy Act (SEPA). To develop the SHC, DNR utilizes forest estate modeling to evaluate different timber harvest scenarios over time. These scenarios must align with existing laws, regulations, and policies, including DNR’s Habitat Conservation Plan and its responsibilities as a trust land manager. DNR is preparing an Environmental Impact Statement (EIS) for the SHC, which will include a “no action” alternative and assess the potential environmental impacts of a range of action alternatives. Public input will be gathered during the Draft EIS public comment period. In addition to the EIS, DNR is conducting an Environmental Justice Assessment (EJA) under the Healthy Environment for All (HEAL) Act. An EJA is a tool used to identify and evaluate how agency decisions may affect overburdened communities, vulnerable populations, and Tribes, particularly in terms of environmental benefits and burdens. It considers both potential harms and opportunities for positive outcomes and helps agencies ensure fair treatment and meaningful involvement of communities that have the greatest environmental and health burdens in decision-making.
