BUSINESS JUSTIFICATION LETTER GGS MIXING UPGRADE.docx

This is a business justification letter for a sole source purchase submitted by the Mississippi Polymer Institute, part of the University of Southern Mississippi (USM), in support of a proposed procurement from Green Science Solutions. The letter justifies the purchase of a Solid Sample Vessel with Mixing upgrade kit designed for the Echo Respirometer system. The upgrade will enable mixing of sample vessels without opening them, thereby reducing weekly labor requirements by several hours. The justification identifies Green Science Solutions as the sole United States-based company capable of providing upgrades and compatible parts for the Echo Respirometer equipment currently in use. The notice of proposed sole source purchase was published on November 19, 2025, with the Mississippi Department of Finance and Administration (DFA) managing the procurement process under RFx 3150006627.

The procurement follows Mississippi Code Section 31-7-13(C) procedures for sole source purchases, with a comment and objection period extending until 8:00 a.m. Central Time. No specific pricing information, contract term, renewal options, or funding source details are provided in the business justification letter. The letter serves as the formal rationale supporting the determination that only one qualified vendor exists to fulfill the technical requirements of this specialized equipment upgrade, eliminating the need for competitive bidding.
