NIGP 49076: Plasticizers : Agriculture Oils, Glutarates, Phthalates, Polymerics, Sulfonamides, etc.

NIGP 49076 Plasticizers: Agriculture Oils, Glutarates, Phthalates, Polymerics, Sulfonamides, Etc. is an Item code under which state and local governments procure chemical conditioning and emulsion polymers for wastewater treatment and biosolids dewatering operations. The code captures specialty polymer products used in municipal infrastructure, particularly solids conditioning agents applied in centrifuge and dewatering processes at treatment facilities. Issuing bodies under this code include state environmental agencies and their subsidiary procurement vehicles, which manage large infrastructure contracts on behalf of regional or statewide treatment networks.

Maryland Environmental Service (MES) posted a Small Business Reserve (SBR) procurement in May 2026 for the furnish and delivery of liquid emulsion polymer at the Freedom Wastewater Treatment Plant in Carroll County, Maryland, with responses due June 15, 2026. The solicitation calls for conditioning and emulsion polymer chemicals for biosolids dewatering, with an estimated annual requirement of approximately 32,200 pounds per year over a five-year contract period (one base year plus four optional one-year renewals). Award is based on lowest total annual polymer cost from a responsible bidder whose polymer meets mandatory performance thresholds—specifically, dewatered sludge cake with a minimum total solids content of 19% by weight during jar testing and full-scale centrifuge trials. The contract is non-exclusive, delivery occurs via tote (approximately 250 gallons) every three weeks F.O.B. destination with 72-hour fulfillment windows, and the SBR set-aside limits award eligibility to certified small business vendors under Maryland State Finance and Procurement Article sections 14-501 through 14-505.
