Annual average concentrations of total dissolved solids (TDS in mg/L) and Fecal Coliform (in #/100 mL) measured on the Truckee River from upstream of the Reno/Sparks urban area (at Mogul) to downstream of the of the Reno/Sparks urban area (at Lockwood). Data obtained from Nevada Division of Environmental Protection (NDEP) and Truckee Meadows Water Reclamation Facility (TMWRF).
integrity in impacted sites. In addition, the type and numbers of fish collected in the study also demonstrated poor biological integrity (USGS 2003). Lamphere et al. (2006) compiled fish and invertebrate data and degree of imperviousness in a watershed to assess impacts such as altered flow regimes and water quality degradation as a result of urbanization, finding that fish and invertebrates both exhibited a strong decline in biotic integrity as a result of urbanization. USGS Circular 1164 details a study using aquatic biologic communities to account for water quality problems as a result of urban runoff, spills, sewage overflows, and chemical contaminants, finding that fish in urbanized watersheds have lower Index of Biotic Integrity (IBI) which demonstrates poor biological condition. Locally, macroinvertebrate and fish species have been collected on the Truckee River by the USGS upstream and downstream from the Reno/Sparks urban area since 1991 in an effort to evaluate river water quality and as part of the NAWQA program (Bevins and Kilroy, 1991; Lawrence and Seiler, 2002). Low quality physical and chemical habitat downstream from the Reno/Sparks urban area has had negative impacts on fish populations (Higgins et al., 2006). Higgins et al (2006) found a decline in biological integrity as the Truckee River travels through the Reno/Sparks urban area, with a reduction in fish species and abundance and a fish IBI score steadily decreasing from Verdi to Marble Bluff Dam (near Pryamid Lake). 2.2 NPDES Storm Water Permit Regulations The Truckee Meadows Structural Controls Program is required under both the federal and state regulations (U.S. EPA and NDEP). In 1987, Congress amended the Federal Water Pollution Control Act (also known as the Clean Water Act) in order to protect receiving water bodies from the impacts of urban runoff. The amendments established a framework for regulating municipal and industrial discharges under the National Pollutant Discharge Elimination System (NPDES) program. According to the Clean Water Act mandate, municipalities regulated under the NPDES program must reduce pollutant loadings in municipal separate storm sewer systems (MS4s) to the “maximum extent practicable” (MEP) and must effectively prohibit non-storm water discharges through their MS4s as a first step toward achieving loading reductions consistent with applicable water quality standards (U.S. EPA, 1997). Sources of storm water runoff that had the greatest potential to negatively impact water quality nationwide were addressed by Phase I of the NPDES Storm Water Program. Under Phase I, the U.S. EPA required NPDES permit coverage for storm water discharges from medium and large MS4s located in incorporated places or counties with populations of 100,000 or more. In EPA Region 9, the NPDES permit program, including storm water permitting, has been delegated to the states of California, Hawaii and Nevada (except for Indian lands in these states). In Nevada, the NPDES Storm Water Program permitting authority is NDEP. The Storm Water Phase I Rule (55 CFR 47990; 16 November 1990) requires all operators of medium and large MS4s to obtain an NPDES permit and develop a storm water management program designed to prevent harmful pollutants from being washed by storm water runoff or dumped directly into the MS4 and then discharged into local water bodies. Per 40 CFR 122.26, large and medium MS4s, such as the Cities of Reno and Sparks and Washoe County, are required to: Provide a description of structural and source control measures to reduce pollutants from runoff from commercial and residential areas that are discharged from the MS4 that are to Truckee Meadows Regional Stormwater Quality Management Program Structural Controls Design Manual, April 2007 Update Section 2 – Storm Water Quality Management Page 2 - 7
