Goldenberg (Miami-Dade Water & Sewer Department) Introduction An L-31N (L-30) Seepage Management Pilot Project (SMPP) public workshop was held on 13January2009 at the South Florida Water Management District (SFWMD) Miami field station to solicit public feedback on the proposed Tentatively Selected Plan (TSP). Kim Taplin welcomed everyone and thanked the attendees for their interest and involvement. Kim said that comments and questions be put on the furnished comment cards for inclusion into the Pilot Project Design Report (PPDR). Kim introduced Tiphanie Jinks as the Army Corps of Engineers (USACE) project manager who will be presenting the project. Tiphanie thanked the attendees and introduced team members in the audience. Tiphanie presented the project through the attached PowerPoint presentation. The presentation included: 1) an introduction to the Pilot Project, 2) alternative comparison and the TSP, 3) status of the project, and 4) public feedback period. Public Feedback Claudio Riedi, representing the Miccosukee Tribe, said that the Tribe generally supports the Pilot Project. He wanted to state for the record that the Tribe will be monitoring activities to ensure the project causes no net wetland impacts, no back pumping into the Water Conservation Area (WCA), and no excessive or permanent noise pollution as stated in the report. He also said that access to Tigertail Camp should not be blocked by the project staging area. Finally, he said that the Tribe has always been against using blasting as a means of excavation for the project, and that the term “blasting” is still used in the report over 100 times. He noted that blasting is not an option as stated in the permit.

Final L-30 SMPP Public Workshop Meeting Summary January 13, 2009 1
Final L-30 SMPP Public Workshop Meeting Summary January 13, 2009 2
Madelyn, representing Friends of the Everglades, said that any water discharged into the Everglades should meet clean water quality standards, and that groundwater flows into the Everglades should not be disrupted if it results in harmful ecological impacts. John Shaffer clarified the project objectives, general hydrodynamic conditions in the area, and anticipated effects of the pilot project. He noted that the pilot is a “test section” that will not have effects that will translate into ecological effects or detectable hydrologic effects outside of the immediate area. Kim Taplin reiterated the objectives of the project and the problem of seepage from the Everglades. Claudio asked what the plans were for full scale implementation if the pilot project works. John Shaffer said that seepage management features similar to the pilot project design would be implemented along the eastern border of Everglades National Park and Water Conservation Area 3B. However, it is likely that implementation would occur incrementally allowing adaptive learning along the way. Claudio asked what technologies would be used for digging. John said that would be left to the contractor, but a continuous excavator is the most likely solution. Someone asked what the period of monitoring and evaluation will be for the pilot project, and who will be conducting the data acquisition. John said monitoring will take place for two years, and that the data will be collected and managed internally. Madelyn asked what groundwater impacts could be expected by constraining groundwater flows through the window. John said that the window was sized to pass existing wet season groundwater flows (about 80-90%), although the overall size of the wall should not result in a detectable retention of groundwater within the WCA even with the window closed. Someone asked what the permeability criteria were for the slurry component. John said that the lower the better. Murika said that would be specified in the plans and specs which have yet to be released. He also asked if the window area was fixed. John said that the sheetpile over the window should allow for resizing the window if necessary. Someone asked if the installation and instrumentation of the wells and monitoring of the data would be performed by the government or by the contractor. Murika said that the details on installation and instrumentation will be in the final specifications. Kim Taplin adjourned the public workshop and encouraged attendees to ask questions of the team in the following minutes informally.
