This contract calls for the City of Spokane’s Wastewater Treatment Facility to procure a comprehensive inventory of compressed gases (medical‑grade oxygen, industrial oxygen, acetylene, argon, nitrogen, etc.) and a wide variety of specialty gas mixtures used for analytical monitoring (zero‑air, ammonia/N₂ blends, H₂S/CO/CH₄ blends, calibration gases, etc.). Quantities range from single cylinders to several hundred units, with unit‑price pricing required for each cylinder size and gas type. Two vendors, Norco and Oxarc, submitted detailed price sheets; the totals indicate a combined potential spend of roughly $127‑$129 K before tax, with an 8.9 % tax applied to the subtotal. The procurement is a competitive sealed‑bid invitation (ITB), with no additional services (installation, maintenance, or training) described.
