February 1, 1988 F2500W.00 Mr. Richard Corneille Utilities Director City of Redlands 30 Cajon Street Redlands, CA 92373 Subject: Upper Santa Ana River Basin Evaluation of Nitrogen Removal Processes Gentlemen: We are pleased to present the following proposal for engineering ser- vices to prepare the Upper Santa Ana River Basin - Evaluation of Nitrogen Removal Processes. A proposed budget is attached. If you concur, please sign one copy and return it at your earliest convenience. SECTION 1 (PURPOSE) The purpose of the AGREEMENT is to provide for engineering services that will be required by the OWNER in general support of the project to evaluate nitrogen removal processes as specifically described below. SECTION 2 (SCOPE OF WORK) The purpose of this project is to provide engineering services for the selection of the best alternative process for nitrogen removal which shall be as follows: Prepare a report Evaluation of Nitrogen Removal Processes. This report would evaluate processes that, when added to the wastewater treatment plant, would reduce nitrogen concentrations to within proposed limits for the Santa Ana River Basin to be set by the Regional Water Quality Control Board. Plants having combined processes (nitrogen and phosphorous removal ) would also be evaluated. Specific areas of work would include: 1. Expanded literature search to identify all viable alternative nitrogen removal processes. The search would also identify plants having combined nutrient removal processes (nitrogen and phosphorous) . Processes would include, but not be limited to, the following: a) Anaerobic denitrification (single anoxic zone), 10840 WARNER AVENUE,SUITE 100 FOUNTAIN VALLEY,CALIFORNIA 92708 TELEPHONE:(714)963-9851 Mr. Richard Corneille Utilities Director February 1, 1988 Page 2 b) Anaerobic denitrification (multiple anoxic zones). c) Anaerobic denitrification coupled with phosphorous precipitation (lime). d) Anaerobic denitrification coupled with phosphorous precipitation (alum) . e) Reverse osmosis, alone. f) Reverse osmosis coupled with pretreatment. 2. Complete an expanded telephone survey to obtain up-to-date performance information on selected installations/processes. 3. Visit and inspect a maximum of six selected installations for at least three viable unit processes, and obtain current operating data for evaluation. Anticipated installations to be visited include: a) Payson, Arizona b) F1 Paso, Texas C) Reno, Nevada d) Largo, Florida e) Hampton, Virginia f) San Francisco, California 4. Meet with the Regional Water Quality Control Board to further establish probable effluent limitations anticipated for nitrogen. 5. Prepare a draft report evaluating the effectiveness of each process and the performance history of selected processes for review by the Owner's staff. 6. Incorporate the most viable process into the Owner's waste- water treatment plant scheme of operation. Prepare a layout identifying the most appropriate location on your site. 7. Prepare a preliminary list of required modifications at the plant site. 8. Present a preliminary project cost estimate, as well as, anticipated operation and maintenance costs. Q. Meet with the Owner's staff at least twice to review the pro- gress. Incorporate comments and prepare a final report. Mr. Richard Corneille Utilities Director February 1, 1988 Page 3 10. Submit a final report. SECTION 3 (TIME OF PERFORMMLEJ As time is of the essence, ENGINEER shall commence work immediately following authorization to proceed. ENGINEER/OWNER have reviewed the job and mutually agree that the following schedule is a reasonable time frame within which to accomplish the work. TIME OF PERFORMANCE Days Following Authorization Item to Proceed 1. Notice to Proceed (from OWNER) 0 2. Literature Search 15 3. Telephone Survey 30 4. Site Visits 45 5. Prepare Draft Report. for OW ER's 60 Review 6. Receive OWNER's Comments 75 7. Final Report to Owner 90 ENGINEER/OWNER mutually agree that they will work earnestly toward meeting the above tentative schedule. Should the scope of work be changed and/or should factors arise during the course of the work effort that could affect the above schedule, it is understood that the OWNER and ENGINEER will develop a revised schedule, if required, to address such scope changes or problems. It is envisioned that all work covered by this task order will be completed by 15 May 88. SECTION 4 (PAYMENT) Payment to the ENGINEER for services performed under this proposal shall be based on the ENGINEER'S Direct Salary times a Multiplier. The Multiplier for this proposal shall be 2.795. A cost ceiling of Twelve 'thousand Two Hundred Forty Three Dollars ($12,243.00) is hereby estab- lished for the envisioned work, and will not be exceeded unless the scope is mutually changed. Exhibit A is attached hereto, and reflects the above costs. ` Mr, Richard Corneille Utilities Director February 1, 1988 Page 4 SECTION 5 (EFFECTIVE TE) This proposal is effective as of the First day 0f February, 1988, CITY OF REDLANDS JOHN CA §LLO ENGINEERS Z } } \ By- \ ?» © ^ ' \ ,. ?^ Gai R.
