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 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 October 2, 2018 the City was re-issued an NPDES permit by the State of Nebraska, allowing municipal stormwater discharges to local waterways and lakes effective November 1, 2018 – October 31, 2023.

For the reporting period September 1, 2017 to August 31, 2018, the City of Lincoln had not yet received the new permit from NDEQ. Per the requirement of NDEQ, the previous permit was administratively extended until the approval and issue of the new permit. This annual report is reflective of the administratively extended period of September 1, 2017 to August 31, 2018.

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 2017-18 fiscal year.

This is a summary of the City’s efforts reported to the Nebraska Department of Environmental Quality for the period beginning on September 1, 2017 and ending August 31, 2018. Note: The City’s fiscal year, which ended August 31, 2018, is slightly different than the NPDES permit year 2018, which ends December 31, 2018.

The City educated 4,000 public and private elementary school children on Garbology.

Watershed Management staff distributed a stormwater “NebGuide” (a series of brochures for installing PDF, designing PDF and landscaping PDF of rain gardens). The City continues to have these brochures printed for distribution.

The City conducted public meetings for five basin planning, watershed master plans, and watershed projects. Invitations were also sent to land owners, various organizations and governmental agencies.

The new Lincoln-Lancaster County Hazardous Materials Collection Center (HMCC) opened on October 4, 2017. Construction of the facility was funded by the City with support from the Nebraska Department of Environmental Quality (NDEQ) and the Nebraska Environmental Trust. The HMCC offered twice per month appointment only hazardous waste collections for homeowners and two hazardous waste collections for small businesses, non-profits and educational institutions that meet the Federal criterial for being Very Small Business Generators. The HMCC served 546 residents and collected 50,000 pounds of hazardous waste from residents in FY 18. In addition to the waste collected at the center, nearly 38,000 pounds of hazardous waste was collected during the year at mobile collection events.

Three hundred fourteen volunteers took part in 32 Adopt A Stream clean up events.

3. Illicit Discharge/Disposal PDF

In Summer-Fall seasons of 2018 the dry weather team monitored 50 outfall sites in Lincoln. Samples were taken at 19 of those sites that were found to be flowing, to detect potential illicit and illegal connections to the storm drain system. Monitoring locations shown in Figure 1 PDF.

The Lincoln Fire Department’s Hazardous Materials (HazMat) team responded to 60 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 PDF).

4. Construction Site Stormwater Programs PDF

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 PDF).

Watershed Management sent a total of 335 “Notice to Comply” to large and small 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 PDF).

6. Pollution Prevention and Good Housekeeping PDF

The City designed, and or constructed, stormwater water quality projects at various locations.

Residential Streets (8,450.6 curb lane 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 (6,939 curb miles).

All business districts were cleaned with street sweepers, typically once every four days (886.5 curb miles).

The combined street sweeping of all types of streets listed above produced 2,811.2 tons of landfill material. This material would have ended up in local streams, creeks and retention ponds if not collected by street sweepers.

Street Sweeping Operations Street Sweeping Operations
