5. By March 15, 2010, the Department of Environmental Protection shall issue revised licenses, as needed, that are based on the revised and approved total maximum daily load report for phosphorus created as a result of the modeling revisions pursuant to this section.

6. Any reallocation of phosphorus among licensed dischargers contributing to algae blooms in Gulf Island Pond must take into consideration all prior total maximum daily load allocations, license limits and attainment of interim or final phosphorus limits as issued in prior total maximum daily loads or licenses so as not to create inequities in regard to attainment of prior phosphorus limits. The purpose of this subsection is to prevent penalizing dischargers who have attained early compliance with prior license limits or total maximum daily load allocations.

7. Any change in license limits based on a revised and approved total maximum daily load for phosphorus must comply with anti-backsliding requirements contained in state and federal law.

8. The Department of Environmental Protection is not obligated to make revisions to the model or existing approved total maximum daily load if funding is not provided for the additional work described in this section.

9. It is the intent of the Legislature that dischargers shall make continuous progress in actual effluent reductions towards reaching final allocations under the total maximum daily load allocations in existence on the effective date of this section or as revised under this section to March 15, 2010.

Sec. 6. Operations study. The Department of Environmental Protection shall supervise a study that evaluates the operation of the dam on Gulf Island Pond with regard to its impact on algae blooms. Hydrodynamic modeling of Gulf Island Pond and the dam must be included in the study as well as an analysis of the dam's operation to determine the feasibility and practicability of forecasting algae blooms and modifying the dam's operation to mitigate the likelihood of the occurrence of algae blooms.

The study must be voluntarily funded by those wastewater dischargers that choose to participate in the study. The study must be completed by September 2008. The operator of the dam on Gulf Island Pond shall cooperate with the department in the conduct of the study, including the submission of any relevant information upon request. If any person demonstrates that the information sought by the department in connection with the study
