DISCUSSION / BACKGROUND
On September 19, 2017 (Item No. 10, File No. 17-0953), the Board approved a three (3) year Agreement with Tetra Tech BAS, Inc., doing business as Bryan A. Stirrat & Associates (Tetra Tech) to provide solid waste, landfill, and wastewater treatment plant engineering and construction quality assurance services on an as-needed basis, primarily for the Union Mine Disposal Site.
On November 19, 2019 (Item No. 16, File No. 19-1391), the Board approved Amendment I to this Agreement, which increased the not-to-exceed amount of the Agreement from $150,000 to $275,000, with no changes to the scope of work or term of the Agreement. The need for Amendment I was a result of increasing requirements of various permitting agencies in which the Environmental Management Department (Environmental Management) has utilized the services of Tetra Tech under the current Agreement, as amended. Specifically, multiple in-depth site assessments, closure and corrective cost updates and estimates, work plans, action plans, mapping updates, site conceptual models, and other various reports have been required during 2019 and 2020 beyond the originally estimated frequency in order to comply with permitting agency requirements for the Union Mine Disposal Site.
