Purpose: In accordance with the Administrative Procedure Act, RCW 34.05.230, the department of ecology submits the following notice that the policy below is now available:

Subject: This policy gives an alternative regulatory option to the requirements of chapter 173-303 WAC, Dangerous waste regulations, for generators of dangerous waste prepreg materials. The policy provides a practical waste management system which is equally protective of human health and the environment. Ecology extended the policy end date to December 31, 2025.

Policy Description: Prepreg fiber materials are widely used in the advanced composite industry, such as the aircraft and aerospace sectors. The interim policy for prepreg waste provides a conditional management and disposal option for oven-cured prepreg waste that is not a federal hazardous waste under 40 C.F.R. Part 261. You may choose to manage some or all of your prepreg waste under the dangerous waste regulations or under the policy. You must follow all of the conditions in the policy to take advantage of these benefits.
