The Applicant proposes to divert the flow of San Juan Creek by pumping brackish groundwater and ocean water from under the ocean within the extension of the alluvial channel associated with San Juan Creek. The Dana Point Ocean Desalination Project, Phase 3 Extended Pumping and Pilot Plant Testing is a continuation of feasibility testing associated with the 2006 construction of a fully buried 12 inch diameter, 350 ft long test slant well on Doheny State Beach. Long term testing is needed to more thoroughly establish water quality parameters and to establish full scale desalting process design. In addition to measuring water quality, the Phase 3 testing will provide information to refine the existing ground water model and to evaluate the Reverse Osmosis process. The testing work will also provide information on the feasibility of using subsurface intakes to avoid marine organism entertainment and impingment impacts associated with conventional open intakes. The Applicant has performed scientific studies that predict the proposed project will not have a significant effect on fish and wildlife resources. However, per recommendation by the Dept., the Applicant submitted a Streambed Alteration Agreement Notification in the interest of opening a file for tracking and monitoring the effects of the test pumping project and for subsequent use in developing appropriate mitigantion measures should the full scale ocean desalination project be implemented.
