DSRSD is also a member of the Livermore-Amador Valley Water Management Agency <br />(LAVWMA), which discharges treated wastewater from the cities of Livermore, Pleasanton and DSRSD <br />into San Francisco Bay by the East Bay Dischargers Authority (EBDA). By contract, DSRSD is also <br />responsible for the operation and maintenance of the LAVWMA facilities. <br />As described in Table ES-1: Impact UTIL-3 of the DEIR, the Project states that the proposed project would <br />not result in a determination by the wastewater treatment provider which serves or may serve the <br />project that it has adequate capacity to serve the project’s projected demand in addition to the <br />provider’s existing commitments. Under the existing Agreement for Wastewater Disposal Services <br />dated November 3, 1992, DSRSD provides wastewater treatment services to the City of Pleasanton. Per <br />the 1992 agreement, any future plans for either a temporary emergency or future connection to the City <br />of Pleasanton’s wastewater collection system would require coordination and review with DSRSD. <br />Provide confirmation that this development was coordinated with DSRSD between 2015-2017 to be <br />included as part of the DSRSD master plan. This should also include the Biological Oxygen Demand <br />(“BOD”) and Total Suspended Solids (“TSS”) shall also be analyzed with the flow. <br />The DEIR provides no evidence to support the conclusion that the additional flow, BOD, and TSS <br />generated by the Project in combination with other reasonably foreseeable future developments would <br />not exceed the City's allocated capacity in the regional WWTP. Water conservation has had a major <br />impact on the ratio of flows to solids that are received at the regional WWTP.
