<br />GREGORY J. WILSON, P.E. <br />Civil Engineer <br /> <br />Experience <br /> <br />Greg Wilson joined Barr in 1993 with six years of experience as a civil <br />engineering intern for Barr and a local municipality. His experience includes <br />hydrology and hydraulics, water quality modeling, geographic information <br />systems (GIS), wetland and National Pollutant Discharge Elimination System <br />(NPDES) permitting, and design applications in water resources. Examples of his <br />experience include: <br /> <br />· Provided storm water pollution prevention planning assistance for several <br />Minnesota cities. Currently working on, or providing technical assistance for, <br />Nondegradation Assessments for the following Selected MS4s to satisfy the <br />MPCA's NPDES Permit requirements: <br /> <br />. St. Louis Park <br />. Lakevi11e <br />. Minnetonka <br />. Bloomington <br />. Plymouth <br /> <br />· Serving as project manager, technical resource, and primary author of <br />Detailed Assessment of Phosphorus Sources to Minnesota Watersheds, <br />prepared for the Minnesota Pollution Control Agency (MPCA). This <br />watershed-based study of phosphorus contributions to Minnesota's surface <br />waters was conducted to inventory the sources and amounts of phosphorus <br />entering three different sizes and categories of publicly owned treatment <br />works (POTWs), and to inventory the poi.nt- and nonpoint-sources and <br />amounts of phosphorus entering Minnesota's surface waters for each major <br />watershed and for the entire state during dry, average, and wet conditions. <br />Additionally, the study determined the effect of various phosphorus source <br />reduction options and assessed options for lowering the point and nonpoint <br />source phosphorus loads to surface waters. The study provided <br />recommendations for further refining phosphorus loading estimates. <br /> <br />· Completing a feasibility analysis for controlling internal phosphorus loads in <br />Spring Lake, as well as in-lake water quality modeling and evaluation of <br />internal and external phosphorus loadings for Spring and Upper Prior Lakes. <br />Work included assessing sediment and phosphorus removal performance of <br />upstream wetland and ferric chloride injection system for the Prior Lake- <br />Spring Lake Watershed District. Presented results at two public workshops. <br /> <br />· Currently developing a feasibi.lity study as a follow-up to the recently <br />completed water-quality modeling study for the Ivy Falls Creek, Interstate <br />Valley Creek, and West/Central/East Highway 13 watersheds of the Lower <br /> <br />Barr Engineering Company <br />
