11.11.1. CENTRAL WASTEWATER TREATMENT '.,+ACILITY. <br />(WWTF) AND REGIONAL SLUDGE PROCESSING FACILITY <br />PROCESS ODOR STUDY PRESENTATION - PROCEED WITH <br />PRELIMINARY IMPROVEMENTS - CDM (CAMP DRESSER &. <br />MCGEE). WGC, AND PBS&J (POST BUCKLEY SCHUH & JERNIGAN) <br />Utilities Director W. Erik Olson reviewed the memorandum re sludge treatment <br />facility and clarified that the wastewater plant is a separate entity from the sludge facility. <br />In the process of working toward a correction of the odor and working witfl the Utilities <br />Advisory Committee, they put together a partnership with the Gifford Progressive League. <br />Joe Idlette and Victor Hart were a big help in this process. PBS&J was hired; Larry Hentz, <br />an engineer with PBS&J and also an elected official, was introduced to .make their report <br />for working on both facilities. <br />Lawrence H. Hentz, Jr., P.E., D.E.E., Vice President of PBS&J, replorted on the <br />study which began with a measuring of the odor of various sulphur compound odors and <br />olfactory tests. To illustrate his remarks he projected photographs and other data for all to <br />see. The purpose was to measure odorous compounds coming from each source and then <br />develop approaches to reduce the odor emissions and thus reduce offsite odor impacts. He <br />gave information on sulfur and the ability of a human being to detect it. He also detailed <br />study objectives; odor detection threshold, probable odor sources, area of odor permeation, <br />types of equipment used, and the recommended improvements to reduce the odors. They <br />are hoping for a 95% solution but at least a 90% reduction in the odor. Their cfTproach is <br />fundamentally sound and scientific and they have recommended the best technology <br />available. (CLERK'S NOTE: A printed copy and CD Rom with Mr. Hertz's visual <br />presentation is on file with the backup in the office of the Clerk to the Board.)', <br />Director Olson commented on the odor depiction on the aerial photograph; displayed <br />by Mr. Hentz. He supported their recommendations. There will be options fo'� others to <br />March 11, 2003 <br />we <br />
