Public Works and Utilities Watershed Management Division
Reporting Requirements Summary
The City of Lincoln is required by federal law to comply with the provisions of the Federal Clean Water Act. In Nebraska, the U.S. Environmental Protection Agency has given the Nebraska Department of Environmental Quality the authority to implement the conditions of the Clean Water Act and the responsibility to insure that municipalities in Nebraska are compliant.
The City of Lincoln complies with these mandated regulations through a State-issued National Pollutant Discharge Elimination System (NPDES permit ). On December 26, 2012 the City was re-issued an NPDES permit by the State of Nebraska, allowing municipal stormwater discharges to local waterways and lakes for the time period 2013-2017.
The following is a list of programs the City has implemented to comply with the State’s requirements for Lincoln’s municipal stormwater NPDES permit. Each program (numbered 1-8) contains a link to an EPA website to provide a summarized description of the requirements. The items listed below are non-inclusive of all efforts made by the City in the 2015-16 fiscal year. The permit year for 2016 ends on December 31, 2016
This is a summary of the City’s efforts reported to the Nebraska Department of Environmental Quality for the period beginning on September 1, 2015 and ending August 31, 2016. Note: The City’s fiscal year, which ended August 31, 2016, is slightly different than the NPDES permit year 2015, which ends December 31, 2016.

The City educated 90 people on methods for making their own compost.
Watershed Management staff distributed a stormwater “NebGuide” (a series of brochures for installing , designing and landscaping of rain gardens). The City continues to have these brochures printed for distribution.
The City conducted public meetings for 12 basin planning, watershed master plans, and watershed projects. Invitations were also sent to land owners, various organizations and governmental agencies.
The City made 1,000 cubic yards of compost available free to the public.

The City put on a program to accept recyclable materials at various locations. Four thousand four hundred thirty-one tons of recyclable materials were collected, including: newspapers, paper, cardboard, glass, tin and aluminum cans. This program was associated with the City of Lincoln’s Waste Reduction and Recycling Program.

June to August 2016, 57 storm drains in Lincoln were monitored for pollutants. Samples were taken at 48 of those sites to detect potential illicit and illegal connections to the storm drain system. Monitoring locations shown in Figure 1 .
Public Works Drainage Maintenance crews reported seepages or septic water intrusion into the storm drain system.
The Lincoln Fire Department’s Hazardous Materials (HazMat) team responded to 233 calls to conduct spill containment for hazardous materials spills. The Health Department conducts investigations and enforcement for HazMat responses as appropriate (some locations are shown on Figure 2 ).
The Health Department responded to 99 illicit discharge incidences. Of those responses, 65 had the potential to impact stormwater and 51 actually did (some locations shown on Figure 2 ). Four of these resulted in an enforcement action.
The Watershed Management Division maintains a database for tracking permits for construction site activity. All of the investigations conducted by Watershed Management were logged in a database and mapped (see Figure 3 ).
Watershed Management sent 186 “Notices” to site owners for miscellaneous violations. Compliance was achieved in most cases. Development areas needing grading certificates were inspected to verify the site was graded and erosion and sediment control measures were installed according to the plan submitted to the City. A total of 19 grading certificate inspections were conducted (see Figure 4 ).
On-site education was provided to construction site owners when City staff became aware of sediment in the public right-of-way.
Watershed Management staff educated 52 people regarding sediment and erosion control compliance.

Property owners installed 29 Best Management Practices that included rain gardens and other types of infiltrating mediums through a City Program with a (50/50) cost share from the Nebraska Department of Environmental Quality.
The City designed, and or constructed, stormwater water quality projects at various locations. A few examples of these projects were the Municipal Services Center vehicle washing station for street sweepers, vacuum trucks, and dump trucks and the N Street Cycle Track Project. Both were completed in 2016.
All residential streets (7,720 curb miles) were cleaned with street sweepers three times per year on a rotating schedule of locations. All arterial streets were cleaned with street sweepers at a rate of typically once every two weeks (5,977 curb miles).
All business districts were cleaned with street sweepers, typically once every four days (1,565 curb miles).
The combined street sweeping of all types of streets listed above produced 3,640 tons of landfill material, or about 280 dump truck loads (typical 10 cubic yard capacity truck). This material would have ended up in local streams, creeks and retention ponds if not collected by street sweepers.
City crews inspected 138 manholes, 1,969 inlets and 48,057 linear feet of piped storm drainage systems to ensure that the City storm drain system is in good repair and that no sanitary lines connect to them.
