13.34.010 - Findings of fact.

The city council adopts this chapter based upon the following findings:

(1) The Federal Clean Water Act ("CWA") provides for the regulation and reduction of pollutants discharged into waters of the United States by extending National Pollutant Discharge Elimination System ("NPDES") requirements to stormwater and urban runoff discharges into the City of Lincoln's ("city's") stormwater conveyance system.

(2) Stormwater flows from individual properties to the municipal storm drain system and then ultimately discharges to Waters of the United States.

(3) The city has obtained permit coverage under the Phase II Small NPDES Permit. Under the provisions of the general permit for the discharge of stormwater from small municipal separate storm sewer systems ("MS4s") ("Phase II Small NPDES Permit"), the city is required to possess the necessary legal authority and implement appropriate procedures to regulate the discharge of pollutants and nonstormwater discharges into the city's stormwater drainage system.

(4) The Phase II Small NPDES Permit requires the city to regulate the contribution of pollutants to the MS4 by stormwater discharges by any user, to prohibit illicit discharges and illegal connections to the MS4, and to establish legal authority to carry out all inspection, surveillance and monitoring procedures necessary to ensure compliance with this ordinance
