Redder, P.E. <br />Security Systems Assessment Support <br /> <br />Yeors Experience: <br />Registration: <br />Education: <br /> <br />4 <br />Professional Engineer, Texas 2004 (#92605) <br />B.S., Civil Engineering, The University of Texas at Arlington, <br />1999 <br /> <br />Mr. Redder has over 4 years experience with Vulnerability Assessments and <br />Emergency Response Planning, water treatment plant expansions, water treatment <br />studies, analysis and laboratory testing. He is an expert on the Safe Drinking Water <br />Act, the Interim Enhanced Surface Water Treatment Rule and the Stage <br />1 Disinfection/Disinfectant Byproduct Rule and has implemented these acts, studies <br />and assessments with great success. Mr. Redder's work focuses on water treatment, <br />therefore the majority of his expertise is with municipalities. <br /> <br />Project Experience: <br /> <br />Water System Vulnerobility Assessment - Brown County WID # 7 and City of <br />Beaumont, Texas. Prepared Water Utility Vulnerability Assessment and new Water <br />Utility Emergency Operations Plan. Provided recommendations for physical <br />improvements and operational and procedure changes. The Water Utility Emergency <br />Operations Plan included procedures to respond to various levels of terrorist threat <br />in response to the National Homeland Security Advisory System Threat Conditions <br />and specific incident response plans. <br /> <br />Water Treotment Plant Exponsion ond Miscellaneous Improvements <br />Project - City of Beaumont, Texas - Design engineer for the WTP expansion to 14 <br />MGD. A hydraulic profile of the treatment plant, which was later used to model the <br />various treatment and piping alternatives, was developed. The profile was used to set <br />elevations and locations of the proposed filters and upflow clarifiers. Various methods <br />of meeting the primary disinfection requirements were modeled. Alternative <br />disinfectants were investigated and a recommendation for the use of chlorine dioxide <br />as the primary disinfectant was made. Disinfection requirements were calculated for <br />the plant's primary disinfection zones, as well as the alternative disinfection methods <br />to be used if the chlorine dioxide system were inoperable. <br /> <br />Safe Drinking Woter Act Implementation Studies - Cities of Grapevine, <br />C/eburne and Longview, and the Greenbelt Municipal and Industrial Water <br />Authority Water Treatment Plants were conducted. The purpose of the studies was to <br />determine if the water treatment plants would have difficulty in implementing the <br />provisions of the Interim Enhanced Surface Water Treatment Rule and the Stage 1 <br />Disinfection/Disinfectant Byproduct Rule, specifically TOC removal and maximum <br />THM and HAA formation. <br /> <br />Tracer Studies - Cities of Arlington and Fort Worth, Texas - Tracer studies were <br />created to determine the baffling ratios of the ozone contactors. This value is used to <br />determine disinfection credit within a portion of a treatment plant. Prior to the testing, <br />the tracer chemical (hydroflousilicic acid) dose was calculated to be used in each test <br />and to calibrate the chemical pumps. Samples were taken and an analysis was made <br />to determine the T1 0 values based on graphical and log-regression analysis of the <br />test data. <br /> <br />Water System Vulnerability Assessment and Emergency Response Plan <br />
