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.
