NIGP 62515: Calibration Equipment, Optical

NIGP 62515 Calibration Equipment, Optical (Item) covers EPA Protocol calibration and audit gases — standardized gas mixtures traceable to NIST reference materials and prepared using EPA G1 methods — that state and local governments procure to support emissions monitoring and environmental compliance operations. The work involves supplying pressurized gas cylinders in calibration and audit-range formulations, maintaining inventory for rapid delivery (typically within 24 hours), providing Certificates of Accuracy, and delivering supporting documentation and customer service. Issuing bodies include county public works departments and environmental/utility agencies operating Continuous Emissions Monitoring Systems (CEMS) subject to air quality district regulations. This is a niche market tied to industrial emissions compliance rather than general laboratory calibration.

Recent activity shows Orange County, California issuing an IFB (Solicitation 0803068001RE, due August 10, 2026) for EPA Protocol calibration and audit gases to support a cogeneration turbine CEMS at its Central Utility Facility under South Coast Air Quality Management District requirements. The County sought 13 line items across calibration and audit-range mixtures on a five-year usage agreement with firm, fixed pricing, cooperative-vehicle extension rights to other municipalities, and a 5% bid-price preference for Orange County Local Small Business (OCLSB) and Disabled Veteran Business Enterprise (DVBE) certified bidders. The procurement includes stringent performance requirements: dual-cylinder initial setup, same-day delivery notification, online and hardcopy Certificates of Accuracy, and most-favored-customer pricing language. One additional solicitation in the block (Sourcewell RFP #061626 for Law Enforcement Equipment, due June 16, 2026) does not involve calibration gases and appears to be a data-collection artifact. Geographic activity is concentrated in California based on available recent records, though the niche nature of EPA Protocol gas procurement suggests limited overall volume across state and local jurisdictions.
