Ruth, General Manager Originator: Ed Torres, Director of Technical Services SUBJECT: Tule Ranch Biosolids Management Contract Amendment GENERAL MANAGER'S RECOMMENDATION Approve Amendment No. 2 to the Agreement for Management of Biosolids with Tule Ranch/Magan Farms, extending the contract term for one year, January 1, 2008 through December 31, 2008, with four additional one year options, for an annual amount not to exceed $6,600,000.; in a form approved by general counsel. SUMMARY • Presently, the Sanitation District contracts with Tule Ranch and Synagro for services to manage its annual production of approximately 240,000 tons of biosolids (650 tons/day). • The Tule Ranch contract with the Sanitation District expires on January 1, 2008. • Tule Ranch currently manages about half of the Sanitation District's biosolids through: o Land application as a Class B biosolids in Yuma County, AZ ($45.44/ton), o Land application of chemically stabilized Class A biosolids in Kern County, CA ($43.07/ton), and o Land fill in Yuma County, AZ ($45.44/ton) (limited capacity). • The biosolids management companies are also compensated to cover only their"pass through" costs when diesel exceeds $2.50 per gallon with truck fuel efficiency of six mpg. • The biosolids management options offered by Tule Ranch in Amendment No. 2 include: o Land application as a Class B biosolids in Yuma County, AZ($46.80/ton), o Land application of a chemically stabilized Class A biosolids in Kern County, CA ($44.36/ton), o Land fill in Yuma County,AZ ($46.80/ton) (limited capacity), o Land fill in Maricopa County, AZ($61.90/ton), and o Transportation to the City of Los Angeles deep-well injection facility at Terminal Island ($11.00/ton). The biosolids injection cost will be negotiated with the City of Los Angeles and brought back to the Board for approval under a separate action. • The existing contract between Tule Ranch and the Sanitation District requires that Tule Ranch shall not charge the Sanitation District fees for biosolids management that exceeds the lowest fee that Tule Ranch charges any public agency for biosolids management. The proposed agreement represents a 3% increase over the previous agreement.

Ruth, General Manager Originator: Nick Arhontes, Director of Operations and Maintenance SUBJECT: Purchase of Ferric Chloride, Specification No. C-2005-247 GENERAL MANAGER'S RECOMMENDATION 1. Approve Change Order No. 3 to Purchase Order No. 102354 OB for Purchase of Ferric Chloride, Specification No. C-2005-247, issued to Kemira Water (previously known as Kemiron Pacific) for a unit price increase of$28.25 per dry ton for ferric chloride, increasing the total price to $462.25 per dry ton plus tax for an estimated amount of$4,029,562 for the period December 1, 2007 through November 30, 2008; 2. Approve procurement of an economical grade of Ferric Chloride SG from Kemira Water, at a unit price $410.00 per dry ton plus tax, for testing during the contract period beginning December 1, 2007 through November 30, 2008, and continued usage in lieu of ferric chloride if the Ferric Chloride SG is deemed to be equivalent in performance, at the aforementioned price, for the remainder of the contract period; and, 3. Approve a 10% contingency for ferric chloride and Ferric Chloride SG, for the remaining two one-year renewal options. SUMMARY • Ferric chloride is an iron salt, which is currently used to increase the solids removal efficiencies at both Plant 1 and Plant 2 in the primary treatment process and to control digester hydrogen sulfide to meet Air Quality Management District (AQMD) requirements. • In fiscal year 2005-06, Kemira Water was awarded a one-year contract to provide ferric chloride after competitive bidding. The contract includes a provision for four one-year contract extensions at the original bid price. • Kemira Water has offered to provide a one-year extension through November 30, 2008, but at a price of$462.25 per dry ton for ferric chloride a proposed increase of$28.25 per dry ton. Board approval is required because the proposed extension is at an increased price. Fqm No ow=-3 ae.nea 0"1 Nl Page 1 Book Page 14 • The raw material cost of steel pickle liquor, ferrous chloride, and hydrochloric acid to manufacture ferric chloride, the cost of power, and transportation costs have resulted in the higher unit costs to customers. • Kemira Water is the only vendor capable of providing the 8,000 dry tons per year of ferric chloride required for District operations. • Kemira Water is also offering a more economical product, Ferric Chloride SG, at a price of S410/dry ton plus tax, which is approximately 10% less in cost. The Ferric Chloride SG is slightly different from the regular ferric chloride in composition and may have detrimental operational impacts. Ferric Chloride SG needs to be tested to determine its efficacy prior to using it as a substitute for the regular ferric chloride. • A survey of the three large wastewater agencies— City of Los Angeles— Hyperion Plant, Los Angeles County Sanitation District and City of San Diego has shown that these three plants are now using Ferric Chloride SG for use in advanced primary treatment. Also, the price paid by these agencies compares favorably with the proposed price for the Sanitation District. • Staff recommends that the contract for ferric chloride be extended for an additional one-year term. PRIOR COMMITTEE/BOARD ACTIONS 1. The contract was competitively bid in fiscal year 2005-06 and awarded by the Purchasing Manager according to Resolution No. OCSD 04-08, Delegation of Authority. 2. 10/25/06: Board of Directors approved Change Order No. 1 for a unit price increase of$76.20 per dry ton for ferric chloride increasing the total price to $434.00 per dry ton plus tax for an estimated amount of$3,255,000 for the period December 1, 2006 through November 30, 2007.

The sewer was constructed in 1980 to replace a 10-inch cast iron pipe. The sewer was televised in 2001 and evidence of crown corrosion was found. The extent of which could not be determined due to extensive debris in the sewer, grease build-up, and other materials coating the crown. Televising was also difficult due to the long length of pipe between manholes. In the first half of 2004, the District added four access manholes to the sewer line to allow for cleaning and CCTV inspection. When the manholes were added, some sections of the existing pipe were removed and found to have corrosion concerns. The pipe was partially cleaned and videotaped. However, the image quality was not adequate to allow for an adequate evaluation of the pipeline condition. In 2005, a corrosion engineer, M.J. Schiff was retained to evaluate the potential for exterior corrosion on the pipeline. The soils were found to be very aggressive from a corrosion standpoint. As a result of this investigative effort, the Bayside Drive Improvement project was chartered on May 5, 2005 to replace or reline the corroded pipeline. This complies with authority levels of the Sanitation District's Delegation of Authority. This item has been budgeted. (Line item: Section 8, Page 32).

Ruth, General Manager Originator: Ed Torres, Director of Technical Services SUBJECT: SUPEROXYGENATION PROCESS FEASIBILITY STUDY, CONTRACT NO. CS-2007-34OBD GENERAL MANAGER'S RECOMMENDATION 1. Approve a Professional Service Consultant Agreement with Alan Plummer Associates, Inc. for the Superoxygenation Process Feasibility Study Utilizing ECO2 Technology, Specification No. CS-2007-34OBD, for a total amount not to exceed $286,850. 2. Approve a 15% contingency ($43,028). SUMMARY • Hydrogen sulfide (HZS) is the principal cause of odors and corrosion in our sewers and treatment plants. HZS is formed only when there is a deficiency of oxygen. In addition, oxygen is dissolved into the water in our activated sludge processes, which provide secondary treatment prior to discharging effluent to the ocean. • Maintaining dissolved oxygen levels is a challenge in normal treatment situations. Bacteria consume the oxygen, and oxygen is released from the water into the atmosphere (effervescence). • A process for dissolving large amounts of pure oxygen in water (superoxygenation) using a device called a "Speece cone" was tested successfully at the Seal Beach pump station in 2005 as part of our efforts to evaluate cost-effective odor control technologies. Other sites using superoxygenation include Camanche Lake in Northern California, a small pump station in Laguna Beach, treatment plants in Indiana and Maine, and a soon-to- be-operating addition to a large headworks at a Texas treatment plant. • Three parts of OCSD's treatment system could benefit from superoxygenation: collections, headworks/ primary treatment, and secondary treatment. The goals in the first two areas would be to provide oxygen to reduce odors and corrosion. In secondary treatment, the goal would be to provide the required process oxygen less expensively than is done now using air blowers or oxygen diffusers. Folm No.Uf M2 R•vivaE=IW Page 1 Book Page 25 • A comprehensive engineering evaluation of the technical feasibility and cost implications of using superoxygenation in the three treatment areas will be done with the assistance of Alan Plummer Associates, Inc. (APAI). This will provide a basis for deciding whether to proceed with the design and construction of in-plant demonstration tests later. • A Request for Proposal process was used to solicit proposals from interested engineering consultants. Of the 26 companies receiving the RFP, 3 submitted proposals, 1 submitted a "no bid" response, and 22 did not respond. A review panel with staff from Technical Services and Operations & Maintenance evaluated the proposals, and APAI was the unanimous choice on a technical basis for the project. The three proposed contract prices ranged from APAI's $286,850 to $645,000. The second and third place proposers' prices were 43% and 125% higher than APAI's price. • A relatively high contingency percentage (15%) is recommended because this is a research project. As such, it has inherently higher risks and possibilities for unforeseen requirements that could affect the project cost than does a construction project or routine process study. PRIOR COMMITTEE/BOARD ACTIONS • In September 2006, the Board approved a reallocation of funds for several research-related projects. This included $150,000 to be applied toward a superoxygenation process study. ADDITIONAL INFORMATION • Subcontractors working with APAI on this project will be Malcolm Pirnie (for their familiarity with the District's treatment processes and equipment) and Oxygen Safety Consultants, Inc. (to provide safety evaluations of possible superoxygenation applications). In addition, APAI will work closely with ECO2 Technologies, the commercial supplier of the Speece cone, who will provide performance and cost information for the proprietary elements of possible superoxygenation installations. • APAI is the engineering consultant for the Trinity River Authority (TRA) superoxygenation installation. This is intended to reduce headworks and primary treatment odors from TRA's 150 MGD treatment plant near Dallas, Texas. • The Speece cone was invented by Dr. Richard Speece, an emeritus professor of civil and environmental engineering at Vanderbilt University, who will provide additional technical assistance as needed during this project. Fmm No.Dwm2.2 Rm W oaro12 Page 2 Book Page 26 • The draft report for this project will be due within six months of the contract's start date. • This complies with authority levels of OCSD's Delegation of Authority.
