SECTION 2 – OVERVIEW OF SERVICES REQUESTED

2.1 DESCRIPTION

Thurston County, Washington, requests Proposals from qualified companies or individuals to provide transport and disposal (by means of beneficial use, or otherwise) of wastewater treatment plant biosolids in Washington State.

2.2 BACKGROUND INFORMATION

Thurston County Public Works owns and operates three activated sludge wastewater treatment plants currently producing roughly 30-50 dry tons of solids annually. Two sequencing batch reactor (SBR) package plants, located in the Tamoshan and Boston Harbor communities in northern Thurston County, are operated to treat sewage and septic tank effluent from small residential populations with a total of 420 service connections. These plants both have minimal solids treatment capacity and do not produce Class B biosolids.

Both WWTPs are operated to store and thicken waste sludge which is then transported to the County’s larger Grand Mound WWTP or other area WWTPs for further treatment. Ultimately all biosolids produced at County owned facilities are removed and transported for beneficial use (or for further treatment) by a Contractor.

The Grand Mound WWTP is an oxidation ditch plant able to treat approximately 0.380 million gallons per day (MGD) of residential and commercial wastewater. The Grand Mound WWTP has a solids treatment process that is able to produce Class B biosolids.

Thurston County currently partners with Three Rivers Regional Facility in Kelso, the City of Aberdeen, and the City of Shelton who accept Class B biosolids or non-class sludge at negotiated rates on a per gallon basis.

Biosolids are transported to these facilities to be processed to Class A biosolids standards and offered to the public or sent to a Class B Beneficial Use Facility (BUF) for land application. Thurston County encourages interested Proposers to identify other appropriate alternatives for cost effective disposal of biosolids.

The transport of all excess solids, whether between County owned WWTPs, from County owned WWTPs, to other WWTPs for further treatment, or directly from WWTPs to BUFs shall be performed under the services contract resulting from this RFP.

2.3 STATEMENT OF WORK

See Attachment 1 Statement of Work which provides the scope of services to be provided.

2.4 CONTRACT PERIOD AND BUDGET

The County anticipates the Contract will be for a maximum duration of five (5) years with an initial one-year term and four one-year renewal options. Option renewals will be exercised at the sole discretion of the County. The Contract value will be for a maximum of $900,000.00. The Contract may be increased to meet the ongoing needs of the County for the services requested up through the Contract period of performance. The County does not guarantee a minimum purchase amount.

2.5 COMPENSATION

A. Mandatory Scope: Payment to Contractor will be based on the negotiated rate schedule and actual quantities/labor hours incurred as verified by individual work orders.

B. Rates shall include all direct and indirect costs and profit.

C. Rates may be adjusted no more than once annually at the time of the option renewal and will be adjusted by no more than 80% of the Consumer Price Index (CPI) – W Seattle-Tacoma-Bellevue (December-December). The County reserves the right to grant the request as submitted, engage the Contractor in a discussion about modifications to the request or deny the request in its entirety. Any change in rates granted by the County shall be affected through a Contract Amendment instituting the rate adjustment and establishing an effective date.

D. The completed Rate Schedule in Attachment 3 will be incorporated into the executed Services Contract.

Statement of Work

1.0 INTRODUCTION/BACKGROUND

Thurston County owns and operates three activated sludge Wastewater Treatment Plants (WWTP) currently producing roughly 30-50 dry tons of solids annually. Two smaller plants, located in the Tamoshan and Boston Harbor communities in northern Thurston County, are operated to treat sewage and septic tank effluent from small residential populations with a total of 420 service connections.

These plants both have minimal solids treatment capacity and do not produce Class B biosolids. Both WWTPs are operated to store and thicken waste sludge which is then transported to the County’s larger Grand Mound WWTP or other area WWTPs for further treatment. Ultimately all biosolids produced at County owned facilities are removed and transported for beneficial use (or for further treatment) by a Contractor.

The Grand Mound WWTP is an oxidation ditch plant able to treat approximately 0.380 million gallons per day (MGD) of residential and commercial wastewater. The Grand Mound WWTP has a solids treatment process that is able to produce Class B biosolids.

Thurston County partners with Three Rivers Regional Facility, the City of Aberdeen, and with the City of Shelton who accept Class B biosolids or non-class sludge at negotiated rates on a per gallon basis.

Biosolids transported to these facilities are either processed to Class A biosolid standards and offered to the public or sent to a class B beneficial use facility (BUF) for land application.

The transport of all excess solids, whether between County owned WWTPs, from County owned WWTPs to other WWTPs for further treatment, or directly from WWTPs to BUFs shall be performed under this contract.

The County anticipates the need for these services on a recurring weekly basis over the next several years. Table 1 provides WWTP historical data on the annual amount of sludge transported and disposed over a 3-year period.
