background

In the past, a focus on water pollution mitigation was aimed at industrial and municipal wastewater treatment plants and the discharges they produced. Significant efforts, resources, and time were channeled into cleaning up these “point sources” (or direct sources) of wastewater.

In response to water quality testing and data, more recent water pollution prevention and mitigation efforts have transitioned toward the widespread clean-up of “non-point source” (or many, many small sources of pollution which affords us, as a community, the opportunity to tackle and eliminate local water pollution that has been generated in individual homes and neighborhoods and then has flowed directly—untreated— into our rivers, streams, and lakes

A major problem with non-point source pollution from a county or municipal perspective is it is very expensive to treat and discharge. Unrealistically costly, very large treatment facilities would have to be built to treat storm peak flows and then those facilities would sit unused more than 95% of the time.

The solution? We can come together as a community to improve stormwater quality by preventing polluted stormwater runoff at the all points of the water cycle.

Regulating Stormwater

Specifically for Salt Lake County, what goes into the storm drain makes its way into the local creek, rivers, and streams. Each of these are part of a larger watershed — the Jordan River Watershed, which lead to major rivers, and eventually to the Great Salt Lake. Because all of the bodies of water are interconnected and not defined geographically by county, state, or city lines, the federal government regulates everything that ends up in the storm drain system.

The federal government regulates stormwater through a permit process, referred to as Municipal Separate Storm Sewer System Permit Program (MS4 Permit Program). Each permit mandates the county to meet specific water quality standards.

Salt Lake County was the first MS4 permitted in 1995. Since then, all cities have joined together to accomplish federal regulations and protect stormwater quality in Salt Lake County. All participating municipalities are in the same watershed and are co-permittees legally at the Department of Environmental Quality, Division of Water Quality. This means combining efforts and outreach because all the waters need protecting in the areas which we maintain.
