Management Manual. The Stormwater Management Manual may contain forms, maps and facility agreements and shall include requirements that are consistent with the following goals: (5) Reduce pollutants of concern that are generated by identified site uses and site characteristics that are not addressed solely through the stormwater quality measures by implementing additional specific source control methods including reducing or eliminating pathways that may introduce pollutants into stormwater, capturing acute releases, directing wastewater discharges and areas with the potential for relatively consistent wastewater discharges to the wastewater system, containing spills on site, and avoiding preventable discharges to wastewater facilities, surface waters or ground waters. Section 4 . Section 9.6791 of the Eugene Code, 1971, is amended to provide as follows: 9.6791 Stormwater Flood Control. (1) Purpose. The purpose of EC 9.6791 is to protect life and property from flood and drainage hazards by maintaining the capacity of the city's stormwater conveyance system through the establishment of flood control regulations for stormwater runoff. (2) Applicability and Exemptions. (a) Except as provided in EC 9.6791(2)(b), flood control standards apply to all development permit applications and land use applications. (b) The standards in EC 9.6791(3) do not apply to development permit applications where the proposed development will be served by a flood control facility that is a manmade drainage system designed to accommodate stormwater run -off generated by the stormwater basin area. (3) Standards. (a) Stormwater flood control facilities shall be designed and constructed according to adopted plans and policies, and in accordance with standards in EC Chapters 6 and 7, and the stormwater flood control provisions and the facility design requirements set forth in the Stormwater Management Manual. (b) Based on the Rational Method flow calculation, stormwater runoff from the development site for the flood control design storm shall be: 1. Discharged into existing stormwater flood control facilities that, considering all developments that have received tentative or final plan approval as of the date the applicant submits a complete application, have the capacity to handle the stormwater runoff; or 2. Retained or detained onsite; or 3. Discharged into a new stormwater flood control facility constructed by the applicant. (4) Underground Injection Control Systems. Stormwater runoff discharged in underground systems is also regulated through the federal Underground Injection Control (UIC) program under Part C of the Safe Drinking Water Act (42 U.S.C. § 300, Chapter 6A, Subchapter XII) and Oregon Administrative Rule Chapter 340, Section 044.
