EPA Proposes Draft Pollution Limits to Restore Chesapeake Bay and Local Waterways

The U.S. Environmental Protection Agency has proposed draft nitrogen and phosphorus limits, called allocations, as part of a “pollution diet” the agency is developing to restore the Chesapeake Bay and its local streams, creeks and rivers.

The watershed-wide draft limits of 187.4 million pounds of nitrogen and 12.5 million pounds of phosphorus are divided among the six watershed states and the District of Columbia, as well as the major river basins. The draft limits were determined using the best peer-reviewed science and through extensive collaboration between the EPA and the seven Bay jurisdictions.

Bay jurisdictions are expected to use the draft allocations as the basis for completing their Watershed Implementation Plans (WIPs), which detail how they will further divide the limits among different sources of pollution and achieve the required reductions. Jurisdictions must provide the first drafts of their WIPs to the EPA by September 1, and final Phase 1 WIPs are due November 29.

“While we all recognize that every jurisdiction within the watershed will have to make very difficult choices to reduce pollution, we also recognize that we must collectively accelerate our efforts if we are going to restore this national treasure as part of our legacy for future generations,” said EPA Regional Administrator Shawn M. Garvin.

The EPA expects the Bay jurisdictions to have all practices in place to meet their established pollution limits by 2025, with 60 percent of the effort completed by 2017. Progress will be measured using two-year milestones, or short-term goals. The EPA may apply consequences for inadequate plans or failing to meet the milestones.

The EPA will issue a draft Chesapeake Bay Total Maximum Daily Load (TMDL) – the “pollution diet” – on September 24, with a 45-day public comment period immediately following. The final Bay TMDL will be established by December 31.

In addition to these draft allocations, the EPA is committing to reduce the amount of airborne nitrogen that falls on the Bay’s tidal waters to 15.7 million pounds per year. This will be achieved through federal air regulations that will be implemented over the coming years.

The EPA will assign draft allocations for sediment on August 15.

Amended Chesapeake Bay Reauthorization Legislation Keeps Firm 2025 Deadline

On June 30, the U.S. Senate Environment and Public Works Committee approved with bipartisan support the Chesapeake Clean Water and Ecosystem Restoration Act of 2009. The bill was introduced last fall by Maryland Sen. Benjamin Cardin and amended to remove provisions that would have codified a Bay-wide “pollution diet,” called a Total Maximum Daily Load (TMDL), for nitrogen, phosphorus and sediment.

The bill now moves on to the full Senate for approval.

The landmark legislation aims to expand federal resources, including funding, authority and enforcement tools, and set a legally binding deadline of 2025 for states to put all necessary measures into place to achieve a healthy, restored Bay. If passed by Congress, it would replace section 117 of the federal Clean Water Act, which authorizes the Chesapeake Bay Program.

The House of Representatives has not yet acted on a similar bill sponsored by Maryland Rep. Elijah Cummings.

EPA proposes draft sediment limits to restore Chesapeake Bay and local waterways

The U.S. Environmental Protection Agency has proposed draft sediment limits as part of a “pollution diet” the agency is developing to restore the Chesapeake Bay and its local streams, creeks and rivers.

The watershed-wide draft limit of 6.1-6.7 billion pounds of sediment per year is divided among the six watershed states and the District of Columbia, as well as the major river basins. In 2009, an estimated 8.09 billion pounds of sediment flowed to and clouded the waters of the Bay and its tributaries. 

Excess sediment suspended in the water is one of the leading causes of the Chesapeake Bay's poor health. The culprits are the tiny clay- and silt-sized fractions of sediment. Because of their small size, clay and silt particles often float throughout the water, rather than settling to the bottom, and can be carried long distances during rainstorms.

When there is too much sediment in the water, the water becomes cloudy and muddy-looking. Cloudy water does not allow sunlight to filter through to bay grasses growing at the bottom of the Bay's shallows. Just like plants on earth, bay grasses need sunlight to grow; without it, these underwater grasses die, which affects the young fish and blue crabs that depend on bay grasses for shelter.

Bay jurisdictions are expected to use the draft allocations as the basis for completing their Watershed Implementation Plans (WIPs), which detail how they will further divide the limits among different sources of pollution and achieve the required reductions. Jurisdictions must provide the first drafts of their WIPs to the EPA by September 1, and final Phase 1 WIPs are due November 29.

“While we all recognize that every jurisdiction within the watershed will have to make very difficult choices to reduce pollution, we also recognize that we must collectively accelerate our efforts if we are going to restore this national treasure as part of our legacy for future generations,” said EPA Regional Administrator Shawn Garvin.

The EPA proposed draft allocations for nitrogen and phosphorus in July.
