Environmental Management Consulting <br /> August 13, 2007 <br /> Caroline E. Sullivan, P.E. <br /> Murray, Smith&Associates, Inc <br /> 2707 Colby Avenue, Suite 1110 <br /> Everett, WA 98201-3566 <br /> Dear Ms. Sullivan <br /> Subject: Scope for Odor Control Support for Everett Lift Station 24 <br /> I appreciate the opportunity to submit this scope and budget for the Odor Control Support for the <br /> upgrading of the City of Everett's Lift Station 24. For projects like this the most efficient way to <br /> evaluate odor control alternatives is in a workshop setting. I all ready have all the cost and <br /> performance data for all the control technologies, so both the quantitative and non-quantitative <br /> evaluations can be completed very quickly. The only time consuming analysis is running the <br /> hydrogen sulfide generation predictive model for the force main. This can be done prior to the <br /> workshop or not done at all. Additionally, the analysis can be just documented in the workshop <br /> minutes or a more formal report can be written. The scope below includes the sulfide model and <br /> the report, but they can be eliminated if you wish. If the model is not run, then the evaluation of <br /> force main control methods is less quantitative. <br /> Scope <br /> Task 1 —Site Visit—This can take place the same day as the workshop(2 hours) <br /> Task 2—Hydrogen Sulfide Predictive Model—The model needs detailed flow, temperature, <br /> BOD, and pipe alignment data(8 hours) <br /> Task 3 —Workshop and Workshop Prep—The workshop will take 1 to 2 hours. I normally <br /> present some background information on odor control technology and then go through what each <br /> technology would look like and how it would perform at this location. (6 hours) <br /> Task 4—Report—If a report is needed it normally takes about a day to complete(8 hours) <br /> Total hours for everything is 24 hours(at$140 per hour is $3,360). Expenses should be limited <br /> to car mileage. My costs for everything should not exceed$3,500. <br /> If we need to further discuss this, please call my office at 360-802-5540. Thank you for the <br /> opportunity to present this. <br /> Sincerely, <br /> Thomas R.
