We need your help! The health of the Chesapeake Bay and Susquehanna River depend on it.

Tell the Maryland Department of the Environment (MDE) that Exelon Corporation – the owner and operator of Conowingo Dam – must play a role in the cleanup efforts around the Dam.

The Conowingo Dam, on the Susquehanna River, has held back sediment and other pollutants for decades, but recent research shows that the Dam reservoir has filled up with sediment and associated nutrients much faster than expected. 

At least 100 million tons of sediment need to be removed!

If a major, catastrophic-level storm happens, this sediment can and will be mobilized and delivered downstream – smothering aquatic grasses that provide food, habitats and oxygen for marine life in the Chesapeake Bay. It’s not a matter of if a major, catastrophic-level storm will happen, but when.

Exelon Corporation has recently filed an application with MDE to re-license the Dam for another 46 years. MDE has the opportunity to approve, deny or place “conditions” on the Dam’s license through this process – and can require that Exelon take steps to mitigate some of the environmental harms this Dam has caused.

MDE needs to hear from you on this important issue! We can’t wait another 46 years before taking action!

The public has until January 15, 2018 to submit written comments to MDE on the re-licensing of Conowingo Dam.

The Conowingo Dam, on the Susquehanna River, has held back sediment and other pollutants for decades, but recent research shows that the Dam reservoir has filled up with sediment and associated nutrients much faster than expected.

This enormous artificial repository can be scoured by high flow events, re-mobilized, and delivered downstream by one catastrophic-level storm (think Hurricane Agnes level). If mobilized and delivered downstream, this sediment can and will smother aquatic grasses that provide food, habitats and oxygen for marine life in the Chesapeake Bay. It’s not a matter of if a major, catastrophic-level storm will happen, but when.

Recently, the owner and operator of Conowingo Dam – Exelon Corporation – filed an application with the Maryland Department of the Environment (MDE) to re-license the Dam for another 46 years. Exelon is required to obtain a 401 Water Quality Certification from MDE, which is a requirement under the Clean Water Act that the Dam will continue to meet the State’s water quality standards. MDE has the opportunity to approve, deny or place “conditions” on the Dam’s license through this process. 

On December 5th, Waterkeepers Chesapeake and Lower Susquehanna Riverkeeper attended a hearing on this re-licensing and recommended that MDE place conditions on the Dam’s license to ensure that Exelon plays a role in the cleanup efforts around the Dam. Without these necessary conditions, MDE must deny the application outright due to its major deficiencies.

Conowingo Dam is a ticking time bomb that requires some major cleanup efforts. The state must address two separate problems - the sediment that is trapped in the Dam’s reservoir and the sediment now flowing through the Dam due to the Dam’s inability to trap any more sediment. This will require dredging the trapped sediment, a suite of upstream best management practices to minimize the sediment flowing through the dam, and resiliency measures downstream to ameliorate the effects of a sediment scour event – like a major storm. 

We recommend that MDE require a myriad of cleanup actions as a condition on the license in order to address the complex problem that is Conowingo Dam. One type of cleanup effort alone will not be enough. For instance, while best management practices (BMPs) upstream can and should be a part of the cleanup efforts, previous studies have shown that if every single upstream BMP were instituted, they would only address about 15-20% of the sediment flow coming downstream and through the dam. Unfortunately, these practices would also do nothing to ameliorate the risk of the trapped sediment behind the Dam from releasing during a catastrophic storm. 

There is an obligation, not only under the state’s 401 Water Quality Certification, but under the Federal Power Act to address water quality improvements and ensure public benefits, like access and public recreation, which will be impacted if not addressed through this license. 

Over the next 46 years, Exelon will bring in billions in revenue for the operation of this Dam, and the Federal Power Act requires a public benefit for using the public resource of the Susquehanna River. Exelon may not continue to profit from this public resource without remediating all of the environmental problems the Dam has created.

If Maryland doesn’t deal with the trapped sediment behind the dam, all of our efforts to clean up the bay and meet the state’s 2025 Total Maximum Daily Load (TDML) goals will be devastated by one major storm. Maryland cannot wait to start these cleanup efforts – Maryland must partner with Exelon and other stakeholders and start the process now.

Ask MDE to ensure that Exelon plays a role in waterway cleanup efforts during the re-licensing of Conowingo Dam. We can’t wait another 46 years before taking action! 

The public has until January 15, 2018 to submit written comments to MDE on the re-licensing of Conowingo Dam.

EPA Guidance Falls Short of Protecting Communities

Air Releases of Hazardous Substances from Animal Waste Will Continue

Sometimes our job as Waterkeepers can get very wonky. And this is one of those times. Not only do we comment on and challenge flawed regulations, we also slog through the guidance documents that the U.S. Environmental Protection Agency (EPA) drafts about how these regulations should be interpreted and applied. Last month, the EPA released a Guidance regarding a new requirement that Concentrated Animal Feeding Operations (CAFO) – known as factory farms -- report the release of hazardous substances from their facilities.

This Guidance came a few months after the D.C. Circuit Court of Appeals ruled that CAFOs are not exempt from the reporting requirements under Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and Emergency Planning and Community Right to Know Act (EPCRA). The decision was meant to close a EPA loophole that has long exempted CAFOs from reporting the same hazardous substances – like ammonia and hydrogen sulfide – as other industries.

The Court reasoned that public health professionals and emergency responders would need this information to adequately respond to emergencies and community threats. Under the ruling, a CAFO owner or operator must notify federal authorities under CERCLA and state and local authorities under EPCRA after it releases a large amount of ammonia or hydrogen sulfide.

The EPA estimates that nearly three-quarters of the country’s ammonia emissions come from CAFOs. According to the Government Accountability Office, the amount of manure from CAFOs ranges from 2,800 tons to 1.6 million tons a year. The manure ends up emitting high quantities of ammonia, hydrogen sulfide, volatile methane and particulate matter after it’s stored or applied to cropland, where it either decomposes or undergoes nitrification and de-nitrification. The ventilation systems in CAFOs also release harmful levels of ammonia emissions. For instance, a study conducted by Iowa State University found that two chicken houses in Kentucky emitted over 10 tons of ammonia in one year.

Ammonia air pollution is associated with some serious health effects, including throat irritation; chemical burns to the respiratory tract, skin and eyes; chronic lung disease; and increased mortality rates.

Despite this, EPA’s Guidance exempts more than ninety percent of the largest CAFOs across the United States from reporting. The EPA justified exempting these CAFOs because they are under a 2005 Animal Feeding Operation Air Compliance Agreement. These compliance agreements were set up so the EPA could develop a reliable way to estimate emissions from CAFOs and determine whether they comply with Clean Air Act standards, but a recent report from the EPA’s Office of the Inspector found that the agency has not been able to make much progress – even after 11 years.

Another glaring issue with EPA’s Guidance is that all farms are virtually excluded from reporting hazardous emissions to state and local authorities. Under the Guidance, any farm that uses manure as part of its “routine agricultural operations” is exempted from the reporting requirements under EPCRA §304. EPA stated that it “believes Congress did not intend to impose EPCRA reporting requirements on farms engaged in routine agricultural operations.”

The “continuous release” reporting required under CERCLA §103 allows for too much uncertainty as it allows for CAFOs to report in “broad ranges” to federal authorities and only requires CAFOs to review their emissions annually.

EPA’s Guidance also falls short of informing CAFO operators and owners on how they should estimate the amount of hazardous substances emitted by their facilities. Despite acknowledging the difficulty in measuring these emissions, EPA does not require any monitoring and allows operators and owners to use their “best professional judgment.”

While this Guidance was meant to educate CAFO owners and operators on how to comply with the recent decision from the D.C. Circuit Court of Appeals, it largely circumvents the Court’s impetus for requiring CAFOs to report hazardous emissions in the first place – to protect communities and provide much needed information for local authorities and emergency responders.

The Guidance and reporting requirements will go into effect on November 15th, but the EPA has requested a stay until January 17th, which the Court has yet to rule on.
