| dc.description.abstract | The Comprehensive Everglades Restoration Plan (CERP) was authorized by Congress in 2000. The main objective of the plan is hydrologic restoration which will be achieved by increasing water storage capacity and redistributing water to reestablish ecologically desirable patterns of depth, distribution, and flow in the freshwater wetlands and salinity regimes in estuaries. CERP contains multiple elements, designed to restore ecosystem function and ensure adequate water supply (storage and distribution) while other efforts are designed to address water quality. The Water Conservation Area 3 Decompartmentalization and Sheet Flow Enhancement (Decomp) Project aims to reestablish sheet flow in the Everglades by decompartmentalization (i.e., removing barriers to flow and unnatural preferential flow paths provided by canals). The goal of Decomp is to hydrologically reconnect a significant component of the Everglades peatland: Water Conservation Area (WCA) 3A, WCA-3B, and Northeast Shark River Slough (NESRS). The Decomp effort will require a significant amount of engineering and deconstruction activities which will result in dramatic alteration to the ecosystem. The Decomp components originally proposed under CERP entails the full or partial removal of several levees, the full or partial backfilling of canals, and alteration of a major roadway, Tamiami Trail. This operational strategy for the DPM was developed to help guide operations of the temporary design-test structure (S-152) consistent with the April 2010 Installation, Testing and Monitoring of a Physical Model for the Water Conservation Area 3 Decompartmentalization and Sheet Flow Enhancement Project Final Environmental Assessment and Design Test Documentation Report (2010 EA) and with the science objectives stated in the 2010 DPM Science Plan. The 2010 EA included a Finding of No Significant Impact (FONSI). Information on the Decomp Physical Model (DPM) design test, a field-scale test, can be found in the 2010 EA. The 2010 EA anticipated operational testing of the DPM to begin in early 2011 and continue until late 2014. Construction of the DPM was delayed. Two operational periods of DPM testing were performed from 5 November 2013 to 30 December 2013 and from 4 November 2014 to 29 January 2015. A Supplemental FONSI was signed on 8 July 2015 to address potential effects of two additional operational periods in 2015 and 2016, not proposed in the 2010 EA. The Supplemental FONSI concluded that two additional operational periods starting in 2015 (October 2015 – January 2016) and 2016 (October 2016 – January 2017) would not result in a significant effect on the human environment. Two additional operational periods of DPM testing were performed from 16 November 2015 to 28 January 2016 and from 17 October 2016 to 31 January 2017. | en_US |
