Duvas Gas

The Texas Commission on Environmental Quality (TCEQ) is soliciting bids for a regional mobile monitoring program focused on procuring specialized calibration and validation gases for ambient air analysis. The procurement involves purchasing specific gas cylinders including BTEX (Blend) at 100 PPB and 10 PPM, Sulfur Dioxide at 100 PPB and 10 PPM, Hydrogen Sulfide at 100 PPB and 10 PPM, Ultra-Pure Zero Air, and Carbon Dioxide Bone Dry. The total procurement includes 7 cylinders of BTEX and SO2, 2 cylinders of H2S and CO2, and 8 Ultra-Pure Zero Air cylinders, with varying lead times ranging from 2 to 6 weeks. Deliverables must meet precise CGA (Compressed Gas Association) standards, with each gas blend requiring specific concentration levels and chemical composition. The procurement is structured as a Request for Bid (RFB) with a submission deadline of October 1, 2025, and vendors must provide gases with certified standards and specific regulator specifications. Vendors will be evaluated based on their ability to meet technical specifications, delivery timelines, and compliance with state procurement regulations.

The solicitation does not explicitly indicate specific set-aside designations or restrictions on respondent types. Vendors must comply with comprehensive state certification requirements, including child support verification, antitrust law compliance, cybersecurity training, and ethical standards. While specific budget ranges are not detailed, the contract will be structured with fixed rates and payment based on actual quantities used, not to exceed the Maximum Authorized Reimbursement. Invoices will be submitted to PSEADINV@tceq.texas.org, and the estimated quantities serve as a guide with the understanding that actual usage may vary. Contractors are required to notify TCEQ's Technical Specialist of any changes in gas shelf life (ranging from 6 months to 2 years) or lead times that differ by more than 5 business days. The procurement appears designed for scientific and environmental monitoring purposes, with a focus on precise gas calibration for regulatory compliance.
