If there is a layer of salt remaining on the driveway or sidewalk after the ice melts, too much salt got sprinkled. If you find excess sand or salt, sweep it up and throw it away so that it is not washed into the storm sewer.
One teaspoon of salt is enough to contaminate five gallons of water forever. Salts, like the de-icers we use in winter, stay in water without settling out contaminating and damaging the North Platte River and freshwater lakes where we fish.

Minimum Control Measure (MCM) #5 of the Stormwater Management Plan
The purpose of this MCM is to ensure the quality of water leaving a previously completed construction site remains continuously treated prior to leaving the property. With the implementation of specifically required Stormwater Treatment Facilities (STFs) the quality of water will have the best chance of remaining clean prior to entering the receiving waters of the state (Platte and Wood Rivers).
As warmer weather melts the snow piles around town, the runoff makes its way to the city’s outfalls where the contaminants can be seen. The swirled sheen on the water’s surface is oil that was trapped in the snow. Snow traps oils, salts and sediment that are released into the runoff as the snow melts. Snowmelt runoff is one of largest sources of urban water pollution.
Minimum Control Measure (MCM) #4 of the Stormwater Management Plan
The purpose of this MCM is to reduce pollutants in stormwater runoff from construction activities that result in land disturbance. An Erosion and Sediment Control program is being followed and an ordinance has been enacted within the City Code. Design standards meeting the Nebraska Department of Environmental Quality (NDEQ) and the National Pollution Discharge Elimination System (NPDES) Permit requirements are available on the City website. There are Erosion and Sediment Control best management practices (BMPs) for a construction site no matter what the size.
Built in 1918, the Scottsbluff Drain originally intercepted groundwater from farm land northwest of the city and redirected it around the budding city to the North Platte River. The photo from the North Platte Valley Museum archives shows Scottsbluff around 1940. The large building is Scottsbluff High School, now Bluffs Middle School. Northwest of the school’s track is a smaller building where Webber’s Furniture now sits on the north end of Broadway.
Today the drain carries groundwater, irrigation wastewater, and stormwater runoff from the part of the county and the majority of the north and northeast sections of town, as seen in the map from MC Schaff. While the city has grown, the Drain remains the nearly the same almost 100 years later.
Minimum Control Measure (MCM) #3 of the Stormwater Management Plan
The purpose of this MCM is to minimize the effect of illicit discharges and illicit connections within the community. An IDDE program is followed and an ordinance has been enacted within the City Code. Dry weather inspections of storm sewer outfalls are regularly performed. A detailed storm sewer system is maintained to track flow of stormwater and identify affected areas from illicit discharges. Access Kearney on the City of Kearney’s website allows the public to acknowledge their concerns regarding all forms of stormwater pollution.
Most cities have two sewer systems: a sanitary sewer and Municipal Separate Storm Sewer System (MS4). The sanitary sewer takes dirty water from our home to the wastewater treatment plant where it is cleaned and released to the North Platte River. The MS4 takes rain and snowmelt straight to the river. That’s why we ask residents to help guard storm drains and the MS4 from chemicals, litter, yard waste or pet waste. When substances other than rain or snow travel in the MS4 they directly pollute the North Platte River, degrading water quality not just for us, but all the way across the state.
Minimum Control Measure (MCM) #2 of the Stormwater Management Plan
The purpose of this MCM partly goes along with the first MCM, Public Education and Outreach. The idea is to use the informed public to get involved to the point of participating in activities that benefit the environment in any way imaginable. With this enthusiasm the public will be spreading the idea of stormwater pollution prevention via word of mouth among members of the community and beyond.
