August 11, 2015 Page 3 of 4 describes the services Barr will perform to implement the treatability testing described in the Report. The purpose of the treatability testing is to provide the scientific and engineering data required to support Banr's professional evaluation, analysis, and recommendation of the preferred technology for full-scale implementation to treat 1,4 -dioxane at WTP 1. The testing will also provide information that is critical to the design of the full-scale modifications to WTPl . Under Work Order Number 1 Barr will procure all equipment and installation services needed to make the pilot treatment systems operational, and will provide all laboratory testing services required. The pilot testing is expected to begin in October and continue through early May, during which time WTPI will be off-line. That timing coincides with the off-peak water demand season when the plant is not needed. The effort will culminate with a report to the city that summarizes the results and provides a recommendation for the preferred technology (expected around June 2016). Subsequent Work Orders under the same Master Services Ag1cclnent will address Barr's professional services associated with fixture phases of the project Staffrequested the Council authorize the City Manager to enter into a Master Services Agreement for the professional services that will be required to address the long-term response to 1,4 Dioxane (DX) in addition to authorizing Work Order 1, Barr Engineering Work Order No. 23621176-01, for the Treatability Testing of 1,4 -dioxane. He noted that the expense of the testing would be covered by City Fund 206, which includes proceeds the City has received for water treatment Mayor Jacobsen asked if the labor intensity during the pilot testing would be monitored. Mr. Kiel explained this would be analyzed by staff during the pilot testing. Councilmember Jacobsen questioned if the Army understood the City would be incurring costs for the pilot testing. City Manager Lotter reported this was the case. Councilmember Jacobsen inquired when a permanent water solution would be in place. Mr. Kiel anticipated that a new system would be in place for the summer of 2018. Councilmember Bauman asked if the new treatment would be integrated into the City's current water treahnent system. Mr. Kiel indicated the iron and manganese treatment process would be used first for the water supply and then the water would flow through the new peroxide treatment system. Councilmember Bauman questioned if spare parts would be maintained onsite. Mr. Kiel commented that this would have to be planned on in order to properly maintain the proposed system. Councilmember Bauman inquired if Arizona went through the same pilot testing. Mr. Kiel stated this was the case noting that the pilot testing allows for the City's engineers to find the proper peroxide and ozone requirements. Councilmember Bauman was pleased by all of the valuable information that City staff gathered from the Arizona site visit Councilmember Burg thanked all of the staff members and consultants, who have been involved in the planning process, that have assisted the City with its plans to coned its water supply. Motion by Councilmember Jacobsen, seconded by Councilmember Bauman to Authorize the City Manager to enter into a Master Services Ag;rcvment for the professional services that will be required to address the long-term response to 1,4 Dioxane (DX); while also Authorizing Work Order 1, Barr Engineering Work Order No. 23621176-01, for the Treatability Testing of 1,4-Dimane. 5 Ayes, 0 Nays -Motion Carried Commission Liaison Iletnorts, Aimoun cements and Updates Dean Latter City Manager Lotter commented he may be appointed to the Metro Arear Water Supply Advisory Committee by the Governor.
