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 the federally mandated regulations of the Clean Water Act 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) has a link to an EPA website to provide a summarized description of the requirements. The items listed below are not inclusive of all efforts made by the City in the 2013-14 fiscal year. The permit year for 2014 ends on December 31, 2014.
This is a summary of the City's efforts that were reported to the Nebraska Department of Environmental Quality for the period beginning on September 1, 2013 and ending on August 31, 2014. Note: the City's fiscal year which ended August 31, 2014, is slightly different than the NPDES permit year for 2014 which ended on December 31, 2014.
- In this permit year the City provided eight rain barrel and rain garden classes through the local community college and at community events.
- The City promoted the fact that it takes just 15 minutes or less for stormwater to reach streams using a movie clip at six local theaters.
- The Parks and Recreation Department provided several programs for elementary school students and the general public which describe positive and negative impacts humans have on the environment. The classes were attended by 9,347 students and their adult leaders.
- The City posted two billboards promoting the importance of picking up pet waste and the Landscape Water Quality Project grant program.
- The City of Lincoln gave away over 100 copies of a booklet of Best Management Practices specifically created for individual and small construction sites. Copies of the booklet were provided to local builders and contractors.
- The City requires a "No Dumping – Leads to Stream" design imprinted into all new precast concrete top sections of storm drains and manhole covers. In the 2013-14 fiscal year, approximately 100 such lids were placed.
- The City provided education to 80 persons regarding methods for making their own compost.
- Watershed Management staff distributed a stormwater "NebGuide" (series of brochures for installing, designing and landscaping of rain gardens). The City continues to have these brochures reprinted for distribution.
- The City conducted six public meetings for basin planning and watershed projects. Invitations were sent to land owners and various organizations and governmental agencies for the meetings.
- The City made 1,000 cubic yards of compost available, free to the public.
- Various departments maintained web pages on the City website which are dedicated to stormwater.
- With assistance through a 319 grant from the State of Nebraska Department of Environmental Quality, the Lower Platte South Natrual Resources District and additional State sponsored funding, the City completed twelve water quality Best Management Practices projects.
- The Health Department provided eight Household Hazardous Waste collection drives in the 2013-14 fiscal year.
- One hundred and five people took part in seven Adopt A Stream clean up events.
- Watershed Management provided information to the public at a booth at the Spring Home and Garden Show. It is estimated that 700 persons stopped by the booth to ask questions or to take a survey.
- The Earth Wellness Festival is an elementary school level program for area 5th graders. It is a one day event where school kids take part in hands on experiments, attend classes and receive information on environmentally based topics. This year's event was attended by approximately 3,000 students.
- The Lincoln Public Schools and area schools provide curriculum for recycling and ecology based classes. Garbology, is an ecology based program that includes water quality components. The classes were provided to 4,086 area 2nd graders.

- The Earth Day Coalition held an "Earth Day" event on April 12, 2014. Watershed Management participated in the event. The event was attended by approximately 2,000 people.
- During the period from June to August of 2014, 51 storm drains in Lincoln were monitored for pollutants. Samples were taken at 12 of those sites. The work was completed to detect potential illicit and illegal connections to the storm drain system. Monitoring locations shown in see Figure 1 .
- Public Works Drainage Maintenance crews reported seepages or septic water intrusion into the storm drain system where encountered.
- The Lincoln Fire Department's Hazardous Materials (HazMat) team responded to 206 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 113 illicit discharge incidences. Of those responses, 70 had the potential to impact stormwater and 11 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 that were conducted by Watershed Management were logged in a data base and were mapped (see Figure 3 ).
- Watershed Management sent 39 "Notices" to site owners for miscellaneous violations. Compliance was achieved in most cases. Development areas that needed a grading certificate were inspected to verify that the site was graded and that erosion and sediment control measures were installed according to the plan submitted to the City. A total of 11 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.

- Property owners installed 19 rain gardens and infiltrating types of Best Management Practices through a City Program with a (50/50) cost share from the Nebraska Department of Environmental Quality. City staff coordinated a "Rain Barrel Art Contest" in which 25 artists were selected to paint barrels that were auctioned off with the proceeds going to the Spring Creek Audubon.
- Forty-four of the 70 Retention/Detention Ponds that were scheduled to be inspected to assess their functionality with regard to reducing pollutants from stormwater runoff and controlling flooding we inspected. The remaining 26 locations were inspected by December 31, 2014 (locations shown on Figure 5 ).
- The City designed and or constructed stormwater water quality projects at various locations including but not limited to the design of water quality BMPs at Parks parking lots, stream stability/water quality projects at Roper Park, several water quality BMPs at the Children's Zoo and stream stability projects in Stevens Creek. Construction has started at a water quality project for Burns Park, Trendwood Park and Roberts Park, and three water quality projects in Antelope Park. Urban street water quality projects have been completed for the 11th Street Green Street project and along P Street in the downtown area. Also completed were a stream stability project for the Old Cheney cutoff just southeast of 14th and Old Cheney, as well as the Green Wall on the Lumberworks Parking Garage near S. Canopy and "N" Streets
