A regional campaign called”Puget Sound Starts Here” was designed to educate the public so that everyone understands that pollution from their home or shop or commercial business becomes part of the greater ecosystem during rainfall. For commercial businesses, that involves regular industrial sweeping and/or commercial pressure washing. These methods provide for the pick-up and disposal of zinc and other heavy metals, oil, solvents, gasoline, and more. An environmentally sound wash stops pollution at its source – and is required by law. Some municipalities ignore this or do a poor job of enforcement, but Bellevue is effective at enforcing environmental laws.
The federal Clean Water Act only requires that pollution not be discharged into the waters of the U.S. without an NDPES permit. According to the U.S. Environmental Protection Agency (EPA), because most pressure washing companies can’t comply with not discharging at all, they comply by ensuring discharge does not reach the waters of the U.S. Companies that do not comply most often discharge their process water into a storm sewer system or directly into a street that drains into a storm water inlet. Most storm drainage systems then discharge directly into the waters of the U.S. without any treatment. This means that pollution sent into a storm drain has the same result as direct discharge into the body of water.
Stormwater management is a recent development in the environmental movement – the city formed the Bellevue Storm and Surface Water Utility in 1974. It was the first fully operational stormwater utility in the country. The goal was to provide for control of stormwater and to reduce flooding, erosion, and property damage while preventing the deterioration of water quality. The many streams, lakes, and wetlands in Bellevue are integral parts of the stormwater system. Since then, Bellevue has remained on the cutting edge of environmental protection. In 1977, 1981, 1988, and 2008, voters approved parks bond measures that provided for city purchase of open space and natural areas. In 1979, the Bellevue city council adopted the Drainage Master Plan, a city wide assessment of flows and potential flooding concerns with a phased approach to capital projects.
In 1984, the original Storm and Surface Water Utility Phase 1 was completed. Bellevue acquired significant wetland areas and constructed additional stream flow storage to remediate runoff. In 1984 and 1995, the city participated in a national urban runoff program and then conducted a second monitoring assessment to detect changes. From this, Bellevue was able to provide a scientific characterization of pollutant levels running off urban development areas and to identify target pollutants for both education and remediation.
And in 2007, Bellevue was issued its NDPES permit. These events all provided growing protection for bodies of water and wildlife. Within a given municipality, all businesses are all required to follow at least as strict environmental laws as are mandated by the federal government. The state and or the municipality may then set and enforce more rigorous standards. Historically, Bellevue has been ahead of the curve when it comes to the environment. This is apparent whenever you travel the city – it is cleaner and greener than most cities.
