In doing so, it is OC San’s responsibility to provide biosolids to the qualified Contractor(s) that meet the specifications described in the following sections. These biosolids are designated for beneficial reuse either through composting, land application, and other qualifying management practices.

The Contractor that provides the best qualifications along with the most responsive and responsible proposal will be considered the Primary Contractor, while the Contractor with the second-best qualifications and responsive and responsible proposal will be considered the Secondary Contractor, etc. The Primary, Secondary, and/or Tertiary Contractors will not be the same Contractor (or any subsidiary to the Primary, Secondary, and/or Tertiary Contractor).
