II. SCOPE OF SERVICES AND SPECIFICATIONS

1. Scope of Services

The City is requesting Bids to secure a source to provide Liquid Biosolids Disposal by Land

Application services for the Southside Wastewater Treatment Plant for use by the Water and Sewer

Department.

All prices quoted shall be based on delivery F.O.B. Tulsa, Oklahoma or to any other points as may

Bids must state the number of Days required for delivery under normal conditions.

2. Specifications

The Bid must meet or exceed the following Specifications.

201.0

GENERAL:

Services will take place at the Southside Wastewater Treatment Plant, which generates

anaerobically digested Class B biosolids that are currently stored in a lagoon prior to liquid

land application.

201.1

The Seller agrees to load, transport, apply and incorporate all biosolids, as required, stored

within the lagoon at the Southside facility. Historically, removal of biosolids has been carried

out to leave approximately one foot (1’) of biosolids in the lagoon to ensure protection of the

clay liner. The Seller, at the option of the City, shall remove all biosolids from the lagoon or

remove biosolids to leave approximately 1 foot remaining. In either case, care must be taken

by the Seller to not disturb the lagoon’s protective clay liner.

The Seller's obligation to complete the removal of material from the lagoon will be 45

calendar days from notification in writing from the City to commence work on the lagoon.

The actual pay quantity will be based upon the volume of material contained in the lagoon

after removal of all readily pumpable material by the City, as determined by measurements

made just prior to commencing work under this Agreement. These measurements shall be

made by City survey crews, with all computations of pay quantity volumes performed by

the City. All survey notes and computations will be furnished to the Seller. The City and the

Seller must arrive at a mutually agreeable volume for the purpose of payment prior to

commencement of work.

The Southside Wastewater Treatment Plant produces, and land applies an average of

3,000,000 gallons of liquid biosolids per year. The quantity stated in Bid Item No. 204.1,

204.2, and 204.3 of Exhibit A, Delivery and Pricing page, is an estimate to be used for

bidding purposes only. The Seller will be paid on a per gallon basis and must provide

sufficient equipment to load, transport, apply and incorporate all biosolids as required within

the IFB.

201.2

Bidders may only communicate with the City through the Assigned Buyer – communication

with other City staff will result in disqualification. The City's contact person during the term

of this Agreement is Steven Meier, Support Services Manager, Water and Sewer

Department (herein referred to as the "Engineer").
