Industrial Stormwater Program
The Tualatin Watershed resources—its streams, lakes, wetlands, groundwater, and the Tualatin River—play an important role in the quality of life we enjoy. They provide us recreation, irrigation and drinking water; support tourism and salmon; and are used by business and industry. These waters, however, are vulnerable to pollution from a wide variety of human activities.
Many of our water pollution problems are due in large part to pollutants that are washed off the land by rainstorms. The quality of stormwater from public facilities, commercial and industrial businesses, and agricultural lands is an increasing concern nationwide. Many people believe that stormwater is clean and does not harm water quality. This perception is understandable since the amount of pollution from any one spot is not usually significant by itself. But when all these small amounts are combined, they can cause significant water quality problems.
The federal Clean Water Act mandates that cities and counties control the quality of stormwater runoff. This mandated program is found in the Code of Federal Regulation part 122.26. Clean Water Services manages this program through a Memorandum of Agreement (MOA) with the Oregon Department of Environmental Quality (DEQ). If your industrial facility falls under the scope of these regulations, you may need to apply for a National Pollution Discharge Elimination Permit (NPDES) for the discharge of rain water to the surface water system. In the State of Oregon this is typically the 1200-Z General Permit.
The goal of Clean Water Services’ Industrial and Commercial Stormwater Program is to reduce the contamination of water resources through emphasis on source control Best Management Practices, because these are very effective and relatively inexpensive. The Industrial Stormwater Program only applies to businesses and non-residential entities within the Clean Water Services' service area in the Tualatin River Watershed.
