REPORT TO COUNCIL
SUBJECT
Title
Authorize the Issuance of a Blanket Purchase Order to Polydyne, Inc. for Polyacrylamide Polymer (F19-097)
Report
REPORT IN BRIEF
Approval is requested to authorize the issuance of a three-year blanket purchase order to Polydyne, Inc. of Riceboro, GA for the purchase of polyacrylamide polymer in the amount not to exceed $2,250,000.
EXISTING POLICY
Pursuant to Section 2.08.040 of the Sunnyvale Municipal Code, Council approval is required for the procurement of goods and/or services greater than $100,000 in any one transaction.
ENVIRONMENTAL REVIEW
The action being considered does not constitute a "project" within the meaning of the California Environmental Quality Act ("CEQA") pursuant to CEQA Guidelines section 15378(a) as it has no potential for resulting in either a direct physical change in the environment, or a reasonably foreseeable indirect physical change in the environment.
BACKGROUND AND DISCUSSION
The Sunnyvale Water Pollution Control Plant (WPCP) must use several chemical products to treat wastewater, including but not limited to high molecular weight cationic polyacrylamide polymers (polymer flocculants) to remove Total Suspended Solids (TSS) and reduce turbidity in the effluent prior to disinfection and discharge to the Moffett Channel located in the lower south bay.
Polymer flocculants are organic chemical compounds used in the dissolved Air Flotation Tanks (AFTs), which are a part of the tertiary treatment process. The Polymer bonds with solids from the secondary effluent to create material that rises to the surface allowing efficient removal in the plant AFTs. Removal of these materials from the wastewater stream is necessary to meet water quality effluent limitations described in the National Pollutant Discharge Elimination System (NPDES) permit and to meet even higher water quality standards for recycled water production. Polymer use at the WPCP is required throughout the year and varies based on seasonal, ...
