VWP SSWD Boundaries

Work impacting state surface waters may require a VWP permit in accordance with VWP program regulations and State Water Control Law. A complete application for a VWP permit requires a State Surface Waters Determination (SSWD) that maps the location of state surface waters within a project site as approved by DEQ through the SSWD process. This layer represents the boundaries of active VWP State Surface Waters Determinations (SSWDs) issued across the state.
