What follows is an excerpt from the Introduction to the manual:


The Source Control Manual is an assemblage of foundational policies that govern drainage and discharges resulting from development activities or specific site uses and characteristics. This manual characterizes site uses, activities, and characteristics and identifies structural, operational, and treatment best management practices designed to control specific types of sources of conventional and toxic pollutants in groundwater, stormwater, and wastewater. These source control management practices are activities, prohibitions of uses, procedures, and other structural or managerial practices that eliminate, prevent, or reduce the release or discharge of pollutants and other harmful impacts to groundwater or the sanitary, combined, or storm sewer system.

The Source Control Manual is part of BES’ Administrative Rules, authorized by Portland City Code (PCC) Chapters 17.34, 17.38, and 17.39. The Source Control Manual was adopted by the Director of BES following a public review process and filed with the City Auditor as required by PCC Chapter 1.07.
