Douglas C. Howie, P.E. is a Senior Stormwater Engineer with the Washington State Department of Ecology (Ecology) in Olympia, Washington. Since the mid-1980's Doug has gained experience in planning, design, construction, and regulation of water related projects. He has worked with stormwater, drinking water, wastewater, and reclaimed water projects throughout his career.
Since 2009, he provides engineering support to Ecology permit managers as they assist jurisdictions and businesses throughout the state in meeting their Municipal, Construction, and Industrial General Permit requirements.
While in this position, Doug edited two volumes of the recent 2019 Stormwater Management Manual for Western Washington (SWMMWW) update in coordination with the reissuance of the most recent 5-year Municipal Stormwater General Permit. The two volumes cover Ecology's requirements for Construction stormwater control and post-construction Runoff Treatment and Flow Control BMPs. In addition, he is the primary stormwater engineer for eastern Washington permittees and is the Department's lead for the Stormwater Management Manual for Eastern Washington (SWMMEW).
Doug also manages the Technology Assessment Protocol - Ecology (TAPE) program where Ecology evaluates emerging stormwater treatment technologies for use in Washington State. Stormwater Utilities across the United States can use results from this program to confirm that they could get adequate treatment from manufactured treatment devices. He is working with the Water Environment Federation to study the potential for a nation-wide evaluation program (STEPP). In this position, he worked with ITRC as a member of the Stormwater BMP Performance Evaluation team on the development of the training document and the Excel tool that users can employ to identify potential runoff treatment BMPs for their project site.
He also worked with the team at Ecology who developed a new Washington State Administrative Code (WAC) for the production and beneficial use of Reclaimed Water (highly treated wastewater from municipal WWTPs). He was the lead editor of the Reclaimed Water Guidance Manual (Purple Book).
Prior to 2009, Doug worked for various engineering consultants where he managed planning, design, and construction projects for stormwater, drinking water, and wastewater facilities.
Doug earned a bachelor's degree in Civil Engineering from Union College in Schenectady, NY in 1978 and a Masters in Engineering Management from St. Martins University in Lacey, WA in 1997. Doug is a licensed PE in Washington and Idaho and an Adjunct Professor in Civil Engineering at St. Martin's University in Lacey, WA teaching statics, surveying, and Stormwater Facility Design classes.
