<br />the Engineer will meet with City representatives at mutually convenient times to assemble <br />this data and information. <br /> <br />1.2 TASK 1 -INITIAL PUBLIC MEETING AND FIELD SAMPLING <br /> <br />Engineer will: <br /> <br />1.2.1 Collect and review available data related to the Project as furnished by the City and <br />specified in Section 2.1. <br /> <br />1.2.2 Conduct an informal meeting with the City to clarify the Project scope, deliverables, <br />schedule, and other pertinent information. This meeting will take place during one of the <br />Engineer's sampling/testing visits described below or will be by conference call. <br /> <br />1.2.3 Provide two persons for each of four days of field sampling and testing to be <br />conducted during August and September, 2001. Engineer will prepare and submit to the <br />City a sampling and testing plan outlining the location and frequency of both liquid and <br />vapor-phase samples to be collected, as well as the analyses to be conducted on each <br />sample. <br /> <br />1.2.4 Collect and arrange for outside laboratory analysis of up to 24 samples (pillows) <br />containing foul air from various collection points. These pillows will be analyzed for <br />mercaptans, reduced sulfide compounds, amines, and other non-hydrogen sulfide <br />odorants. <br /> <br />1.2.5 Participate in an informal public meeting to coincide with one of the sampling/testing <br />days. <br /> <br />1.2.6 Prepare a technical memorandum summarizing the findings of this sampling and <br />testing effort and provide three copies of the memorandum to the City. <br /> <br />1.3 TASK 2 - DISPERSION MODELING AND EVALUATION OF ALTERNATIVES <br /> <br />The Engineer will: <br /> <br />1.3.1 Develop a dispersion model for the City's Wastewater Treatment Plant using <br />emissions data collected under Task 1. The model will include long-term atmospheric <br />data, topographic data, and geometric information describing the major treatment units at <br />the plant. The intent of the model will be to predict and graphically present the intensity <br />and/or frequency of odorants at selected receptor locations around the plant, and to assess <br />and project the effectiveness of various control alternatives considered. <br /> <br />1.3.2 Run dispersion model and provide results to the City for existing conditions, <br />proposed future Biological Nutrient Removal (BNR ) conditions, and to simulate the effects <br />of various odor control technologies to be evaluated. <br /> <br />2 <br />
