Any supplier, who manufactures, sells or supplies IT goods or services may petition VITA to include requirements for less toxic goods and services into its procurement process. The supplier shall submit, prior to or during the procurement process, documentation which establishes that the IT goods or services being offered meet the applicable performance standards. If VITA determines that the documentation establishes that the less toxic products meet or exceed the performance standards set forth in the applicable specifications, VITA shall incorporate the specifications for the less toxic goods and products into its procurement process. Agencies procuring IT goods and services under their delegated procurement authority are instructed to revise their procedures and specifications on a continuing basis to encourage the use of less toxic goods and products; however, agencies are not required to purchase, test or evaluate any particular good or product other than those that would be purchased under regular purchasing procedures. (Code of Virginia, § 2.2-4314).
