17、4A 32.8.10 Manuals. The analyzer shall be delivered with operator, maintenance, and illustrated parts manuals. Format and quantity shall be as specified in the contract or order. 3. REGULATORY REQUIREMENTS 3.1 Recycled, recovered, or environmentally preferable materials. Recycled, recovered, or envi

18、ronmentally preferable materials should be used to the maximum extent possible provided that the material meets or exceeds the operational and maintenance requirements, and promotes economically advantageous life cycle costs. The offeror/contractor is encouraged to use recovered materials to the max

19、imum extent practicable, in accordance with paragraph 23.403 of the Federal Acquisition Regulation (FAR). 3.2 Green Procurement Program. Green Procurement Program (GPP) is a mandatory federal acquisition program that focuses on the purchase and use of environmentally preferable products and services

20、. GPP requirements apply to all acquisitions using appropriated funds, including services and new requirements. FAR 23.404(b) applies and states the GPP requires 100% of EPA designated product purchase that are included in the Comprehensive Procurement Guidelines list that contains recovered materia
