| Reason for Recommended Action/Background |
Prior to construction of any Waste Management Unit (WMU) at the landfill, the plans and specifications must be reviewed and approved by the Central Valley Regional Water Quality Control Board (Regional Board). The attached plans and specifications have been submitted to the Regional Board, and are currently under review. The Division does not anticipate any substantial comments from the Regional Board, however an action item has been included to authorize the Director, Division of Integrated Waste Management to make any changes required by the Regional Board.
The plans and specifications were prepared by Golder Associates under an agreement approved by the Board on December 15, 2020 and in accordance with the requirements set forth in Title 27 of the California Code of Regulations.
Construction of new modules at the landfill requires significant amounts of soil (approximately 30,000 cubic yards per acre) due to the relatively shallow groundwater at the site. Because of this, the overall project is being split up into two phases. This first phase is primarily limited to soil placement to construct the subgrade for the next module. Construction will occur during fiscal year 2021/2022, likely August through October. A subsequent set of plans and specifications will be presented to the Board later this year with the remaining portions of construction occurring during the summer of 2022.
The engineer's estimate for this phase of the project is $2,615,248, which includes a 20 percent contingency. Funding for this phase of the project will come from Sanitation Enterprise Fund reserves as part of the 2021/2022 fiscal year budget. |
| Collaborations (including Board advisory groups and external partner agencies) |
| The Regional Board is currently reviewing the plans and specifications. |
