>The EPA Office of Water has released a report describing activities implemented in 2008 to respond to the challenges posed by a changing climate. The report is divided into three major sections:

a description of activities to implement the National Water Program Strategy: Response to Climate Change, including the 44 key actions in the Strategy;

a review of water-related climate change activities in EPA Regions; and

a summary of EPA climate and water-related activities not specifically addressed in the Strategy.

During 2008 the Office of Water made substantial progress implementing the Strategy. Work on all but three of the 44 key actions has been initiated. For most of these actions, interim milestones and schedules have been accomplished and work is on schedule. Some highlights of successful implementation efforts include:

publication of proposed regulations designed to assure that geologic sequestration of carbon does not pose a threat to underground sources of drinking water;

development of the “Climate Ready Estuaries Program;” and

establishment of a Federal Interagency Workgroup on climate change and water matters.

>The U.S. Environmental Protection Agency (EPA) and the Florida Department of Environmental Protection (FDEP) are taking actions to protect and restore both recreational uses and aquatic life in Florida waters. These actions include EPA issuing a formal determination under the Clean Water Act that ‘numeric’ nutrient water quality criteria are necessary in Florida, and Florida accelerating its efforts to adopt numeric nutrient criteria into state regulations. Numeric nutrient criteria will significantly improve Florida’s ability to address nutrient pollution in a timely and effective manner.

Excess nitrogen and phosphorus levels (nutrient pollution) in waterbodies can cause harm to aquatic ecosystems and threaten public health. Nutrient pollution can lead to water quality problems such as harmful algal blooms, low-oxygen ‘dead zones’ in water bodies and declines in wildlife and wildlife habitat. These effects also disrupt recreational activities and pose threats to public health.

Water quality degradation from nutrient pollution is a significant environmental issue in Florida. Florida’s 2008 Integrated Water Quality Assessment revealed that approximately 1,000 miles of rivers and streams, 350,000 acres of lakes, and 900 square miles of estuaries are impaired by nutrients. The actual number of miles and acres of waters impaired for nutrients is likely higher, as many waters that have yet to be assessed may also be impaired.

Local governments in Florida have worked to improve wastewater treatment and stormwater management. In addition, many in the agricultural community have implemented best management practices for nutrient control.

The federal determination is intended to build upon the substantial investments that Florida has made in nutrient data collection, analysis, and stakeholder involvement, and is fully consistent with the State’s and EPA’s commitment to a stronger nutrient control program. The new numeric nutrient water quality standards will help Florida improve the efficiency and effectiveness of its water quality management tools, identify waters impaired because of nutrient pollution, establish Total Maximum Daily Loads and Basin Management Action Plans and derive National Pollutant Discharge Elimination System permit limits.
