NIGP 18012: Ammonium Hydroxide (Aqua Ammonia) and Amines

NIGP 18012 Ammonium Hydroxide (Aqua Ammonia) and Amines, an Item code, covers bulk chemical supply to municipal water and utility infrastructure — specifically aqueous ammonia and related nitrogen compounds used in water treatment, wastewater operations, and emissions control at energy facilities. State and local water utilities and municipal power authorities are the primary buyers under this code; recent solicitations show cities purchasing supplies on fixed-term contracts (12 to 24 months) with delivery tied to operational schedules and strict compliance with water-quality standards, DOT hazmat regulations, and safety certification requirements.

The City of Ashland, Oregon and the City of Austin Electric Utility (Austin Energy) posted the two most recent opportunities. Ashland issued an ITB on May 19, 2026, due June 9, 2026, for nine chemicals including ammonium-based compounds for its Water Treatment Plant and Wastewater Treatment Plant, with 12-month award terms beginning July 1, 2026, and delivery FOB Ashland with estimated annual volumes ranging from 18,000 to 650,000 pounds depending on the chemical. Austin Energy issued an IFB on May 11, 2026, due June 9, 2026, for 19% aqueous ammonia delivered in bulk tank-truck volumes (5,000 to 6,000 gallons per load) to Sand Hill Energy Center for nitrogen oxide suppression, with a 24-month primary term and optional three 12-month renewals; the contract included local and small business preference discounts of up to 5 percent for bids under $500,000. Both jurisdictions required chemical analysis documentation, comprehensive insurance (including environmental liability for the energy utility), and compliance with state tax and nondiscrimination requirements; neither solicitation specified a budget range or named an incumbent. Activity spans the West and South, with Oregon and Texas representing the documented geographic footprint in this recent window.
