Russell U. Redder, P.E. Security Systems Assessment Support Years Experience: 4 Registration: Professional Engineer, Texas 2004 (#92605) Education: B.S., Civil Engineering, The University of Texas at Arlington, 1999 Mr. Redder has over 4 years experience with Vulnerability Assessments and Emergency Response Planning, water treatment plant expansions, water treatment studies, analysis and laboratory testing. He is an expert on the Safe Drinking Water Act, the Interim Enhanced Surface Water Treatment Rule and the Stage 1 Disinfection/Disinfectant Byproduct Rule and has implemented these acts, studies and assessments with great success. Mr. Redder's work focuses on water treatment, therefore the majority of his expertise is with municipalities. Project Experience: Water System Vulnerability Assessment - Brown County WID # 1 and City of Beaumont, Texas. Prepared Water Utility Vulnerability Assessment and new Water Utility Emergency Operations Plan. Provided recommendations for physicaf improvements and operational and procedure changes. The Water Utility Emergency Operations Plan included procedures to respond to various levels of terrorist threat in response to the National Homeland Security Advisory System Threat Conditions and specific incident response plans. Water Treatment Plant Expansion and Miscellaneous Improvements Project - City of Beaumont, Texas - Design engineer for the WTP expansion to 14 MGD. A hydraulic profile of the treatment plant, which was later used to model the various treatment and piping alternatives, was developed. The profile was used to set elevations and locations of the proposed filters and upflow clarifiers. Various methods of ineeting the primary disinfection requirements were modeled. Alternative disinfectants were investigated and a recommendation for the use of chlorine dioxide as the primary disinfectant was made. Disinfection requirements were calculated for the plant's primary disinfection zones, as well as the alternative disinfection methods to be used if the chlorine dioxide system were inoperable. Safe Drinking Water Act Implementation Studies - Cities of Grapevine, Cleburne and Longview, and the Greenbelt Municipal and Industrial Water Authority Water Treatment Plants were conducted. The purpose of the studies was to determine if the water treatment plants would have difficulty in implementing the provisions of the Interim Enhanced Surface Water Treatment Rule and the Stage 1 Disinfection/Disinfectant Byproduct Rule, specifically TOC removal and maximum THM and HAA formation. Tracer Studies - Cities of Arlington and Fort Worth, Texas - Tracer studies were created to determine the baffling ratios of the ozone contactors. This value is used to determine disinfection credit within a portion of a treatment plant. Prior to the testing, the tracer chemical (hydroflousilicic acid) dose was calculated to be used in each test and to calibrate the chemical pumps. Samples were taken and an analysis was made to determine the T10 values based on graphical and log-regression analysis of the Innovative approaches . . test data. saimis FrNS* m Nichol• practical results Water System Vulnerabiliry Asse:smen[ and Emergency Response Plan
