Common use of Shark River Slough Clause in Contracts

Shark River Slough. The Consent Decree of 1995 specified that interim and long-term total phosphorus (TP) concentration limits for discharges into the Everglades National Park (ENP) (Figure 3) through Shark River Slough be met by October 1, 2003, and December 31, 2006, respectively. It was specified that the TP concentrations be presented as 12-month flow-weighted means. Only the TP concentrations for the water year ending September 30th are evaluated for compliance with the Consent Decree limits. The long-term TP concentration limit for inflows to Shark River Slough through structures S12A, S12B, S12C, S12D and S333 represents the concentrations delivered during the Outstanding Florida Waters baseline period of March 1, 1978, to March 1, 1979, and is adjusted for variations in flow. Inflow concentrations of TP through Shark River Slough are compared to the interim and long-term limits at the end of each water year (October 1st through September 30th) from 1991 to 2007 (Figure 4). The 12-month flow-weighted mean TP concentration for October 2006 through September 2007 was 9.8 ppb. The corresponding long-term limit, which became effective on December 31, 2006, was 11.8 ppb. Table 2 presents the 12-month flow-weighted mean concentrations for each month as well as the corresponding interim and long-term TP concentration limits, calculated using the 12-month period flow. Supplemental water quality samples were collected at some of the Shark River Slough monitoring sites from January 2006 through September 2007, but only the bi-weekly compliance monitoring grab concentration data were used for flow-weighted mean TP concentration calculations. Routine monitoring was changed to weekly1 for all Shark River Slough sites beginning in October 2007. In accordance with Appendix A of the Consent Decree, only the every-other-week grab concentration data were used for the flow- weighted mean calculations from October 20072. For the 12-month periods ending in April, May, and June 2008, the 12-month flow-weighted mean TP concentrations were 12.2, 12.0, and 11.7 ppb, respectively. The long-term limits were 12.9, 12.6 and 12.6 ppb, respectively. The 12-month flow- weighted mean TP concentrations were lower than the long-term limits for the months of April, May, and June 2008. 1 S12A and S333 are sampled weekly if flowing, otherwise monthly. S12B, S12C, and S12D are sampled weekly if flowing.
