Washington Revised Code Title 70A. Environmental Health and Safety § 70A.15.2220. Existing stationary source--Replacement or substantial alteration of emission control technology

Any person proposing to replace or substantially alter the emission control technology installed on an existing stationary source emission unit shall file a notice of construction application with the jurisdictional permitting authority. For projects not otherwise reviewable under RCW 70A.15.2210, the permitting authority may (1) require that the owner or operator employ reasonably available control technology for the affected emission unit and (2) may prescribe reasonable operation and maintenance conditions for the control equipment. Within thirty days of receipt of an application for notice of construction under this section the permitting authority shall either notify the applicant in writing that the application is complete or notify the applicant in writing of all additional information necessary to complete the application. Within thirty days of receipt of a complete application the permitting authority shall either issue an order of approval or a proposed RACT determination for the proposed project. Construction shall not commence on a project subject to review under this section until the permitting authority issues a final order of approval. However, any notice of construction application filed under this section shall be deemed to be approved without conditions if the permitting authority takes no action within thirty days of receipt of a complete application for a notice of construction.
