The City has an ordinance that prohibits illegal dumping and illicit discharges.

An illicit discharge is the discharge of anything into the storm drainage system that is not clean stormwater. (Stormwater is water that is generated from a precipitation event.) The dumping of trash or other discarded items not only pollutes our waterways but also costs money to cleanup and causes our City to look unsightly.

Illegal Dumping

Areas surrounding the drop box recycling locations are not dumpsites. It is illegal to dispose of waste generated at a location other than where it was generated without the expressed legal permission of the property owner and/or the City of Lincoln.

Materials commonly dumped illegally include, but are not limited to: recyclables not in the drop box containers, yard waste, furnitureappliances, auto waste (tires, oil, antifreeze, and parts), and concrete.

Illegal dumping in our community costs everyone and will be prosecuted per Penal Code §324.3. Please help keep the community clean by disposing of unacceptable items properly and not leaving recyclables outside the drop boxes.

Illicit Discharges

The City Council adopted Ordinance 894B that formalizes Chapter 13.34, Illicit Discharge and Illegal Connection Control, of the Municipal Code, and further establishes the City’s Illicit Discharge Program. The intent of the program is to minimize the discharge of pollutants and prohibited non-stormwater materials into the City’s storm drainage system and to eliminate, detect, and remove illegal connections to the storm drainage system. Illicit discharges are any non-stormwater related discharges to the storm drain system that are prohibited under local, State, and Federal law. These occur when liquids or materials are dumped, spilled, poured, sprayed, or leaked onto outdoor surfaces, where they can enter the storm drain system and be washed into creeks and ravines by rain or irrigation water.

Some examples of common illicit discharges include:

• Pet waste left on the sidewalk
• Excess irrigation water leaving landscaped areas
• Overuse of pesticides, herbicides, and fertilizers
• Oil drippings from a leaky car
• Leaking or overflow from trash dumpsters
• Excess car wash water draining into the street
