NIGP 18060: Isotopes and Their Compounds (Organic and Inorganic)

NIGP 18060 Isotopes and Their Compounds (Organic and Inorganic), an Item code, covers specialized gas mixtures and calibration standards that state and local governments procure to support environmental monitoring, emissions compliance, and laboratory operations. The scope of work centers on EPA Protocol calibration and audit gases—precisely formulated gas mixtures prepared using EPA-approved methods and traceable to National Institute of Standards and Technology (NIST) reference materials. These gases serve critical operational functions: supporting continuous emissions monitoring systems (CEMS) at municipal utility facilities, validating air quality monitoring equipment, and ensuring compliance with environmental regulations such as those enforced by the South Coast Air Quality Management District. Suppliers typically deliver gases in standardized cylinders, maintain rapid-response inventory programs, and provide technical documentation including certificates of accuracy. Issuing bodies under this code include county utilities and public works departments; the recent activity reflects municipal procurement driven by regulatory requirements rather than discretionary purchases.

Orange County, California, OC Public Works, issued a competitive bid (Solicitation 0803068001RE, due August 10, 2026) for EPA Protocol Calibration and Audit Gases to supply a cogeneration gas turbine CEMS at the Central Utility Facility in Santa Ana—a five-year fixed-price usage agreement covering 13 line items of calibration and audit gas mixtures. The County applied a 5% bid-price preference (capped at $100,000) for Orange County Local Small Business (OCLSB) or Disabled Veteran Business Enterprise (DVBE) certification, required Performance and Labor and Material Payment Bonds, mandated same-day delivery notification and 24-hour reorder fulfillment, and reserved the right to extend the contract as a cooperative purchasing vehicle to other municipalities, public utilities, educational institutions, and nonprofit or governmental organizations. The scope reflects the typical deployment pattern for this code: specialized, regulated procurement by utilities and environmental agencies in response to specific compliance obligations rather than broad market demand.
