Mark Richards, P.E. <br />• WaterQuality Modeler. Constructed QUAL2E water quality model to analyze <br />the effectiveness of various water quality unprovement technique along a <br />100-mile long section of the Snake River to reduce phosphorus and <br />chlorophyll concentrations in the river. Coordinated with numerous <br />agencies such as Idaho and Oregon DEQs, EPA, USGS, Idaho Powex <br />Company, Boise City and six wastewater treatment plants along the reach to <br />gather the required data to construct and operate the model. <br />Watershed Management, City of Lincoln, Nebraska <br />WaterQuality Modeler. Assisted in the development of a detailed predictive <br />sunulation ammonia model to provide a scientific basis for the development <br />of site-specific ammonia criteria and appxopriate NPDES pexmit limits. <br />Watershed Modeling, Cherry Creek Board Water Quality Authority, Colorado <br />WaterQuality Modeler. Developed watershed based predictive model for <br />phosphorus loading to assist in the determination of a Tota1 Maxunum <br />Annual Load to Chexry Creek Reservoir. Assisted in the selection and <br />screening of pollution reducing facilities and best management practices in <br />the watershed. <br />Dissolved Oxygen Modeling, City of EI Paso, Texas <br />WaterQuality Modeler. Examined instream water quality impacts fxom the <br />dischaxge from wastewater treatment plant on two receiving waters to <br />• support NPDES permit renewal. Explored the potential for water quality <br />standard violations undex various operational and flow conditions. <br />Wastewater Treatment Plan Study, Boulder, Colorado . <br />HydraulicModeler. Performed hydxaulic analyses to evaluate the present <br />opexations and futuxe design alternatives of the Bouldex, Coloxado <br />Wastewater Treatment Plant. <br />Main Pumping Station Ely Wastewater Treatment Plant, Ely, Minnesota, Public <br />Utilities Commission <br />HydraulicModeler. Performed the hydxaulic analysis to assist in the design of <br />the Ely, Mimiesota Wastewater Txeatment Plant. Coordinated the selection <br />of the pumps, compressars, blowexs, air diffuser system and other <br />equipment for the plant. <br />Grand Rapids, Michigan <br />HydraulicModeler. Perfortned hydraulic analyses to evaluate the present <br />operations and future design alternatives of the Grand Rapids, Michigan <br />Wastewater Txeatment Plant. <br />• <br />m:4esumes\Richards Mark.doc
