Forest Practices Approval/Notification - Western Washington, Class IV-Special

What is the purpose of this permit?
The Department of Natural Resources (DNR) regulates forest practices on private and state forest land. A permit is not required for every forest practice, but the forest practices rules must be followed when conducting all forest practices activities. There are five classes of forest practices depending on the types of activities being proposed and their potential impact to public resources (see WAC 222-16-050). Once an application is received by the department it gets assigned a classification which in turn determines the type of permit. A Class IV Special permit to conduct a forest practice in Western Washington is called a Class IV-S Forest Practices Application (Class IV-S FPA). This permit type is for forest practice activities that have the potential for a substantial impact on the environment. The following activates are examples of the types of proposals that may qualify for the Class IV-S FPA permit in Western Washington: specified forest practices on lands designated as critical habitat of threatened or endangered species, forest practices activities within the boundaries of a national, state, or any park of a local government, forest practices on potentially unstable slopes or landforms that have the potential to deliver sediment or debris to a public resource or have the potential to threaten public safety. Most Class IV-S FPAs have a minimum review period of 14 days. The review periods for Class IV-S FPAs can extend to 30, 60, or 90 days depending on the type of FPA submitted. Below is a bulleted explanation of these review periods:
