Clean air advocates and environmental groups won a victory today when Power4Georgians (P4G), the only company trying to develop expensive new coal plants in Georgia, agreed to cancel the proposed Ben Hill coal-fired power plant. The company also agreed to comply with critical new safeguards against mercury pollution and invest $5 million in energy efficiency and renewable projects. The Sierra Club, the Fall Line Alliance for a Clean Environment (FACE), Southern Alliance for Clean Energy (SACE), and the Ogeechee Riverkeeper, represented by the Southern Environmental Law Center and GreenLaw, successfully challenged the permit for Plant Washington issued by the Georgia Department of Environmental Protection, and the settlement agreement is pending approval by each group. If built, Power4Georgians’ Plant Washington will have to meet the much more protective emission standards for mercury and other air toxins.
“Before we challenged the permit, Plant Washington was going to send forty times more mercury into our air and water each year, endangering our most vulnerable citizens,” said Colleen Kiernan, director of the Georgia Chapter of the Sierra Club. “We knew the law was on our side, we challenged Power4Georgians, and now Georgia’s air, water and people will be protected.”
Plant Washington now faces its steepest challenge yet, as U.S. Environmental Protection Agency (EPA) recently announced the carbon pollution rule for new coal-fired power plants, which will require new coal plants to reduce or capture their harmful carbon emissions. Power4Georgians had not considered carbon capture technology in the original Plant Washington proposal. In the rule, EPA identified Plant Washington as a potential “transitional” source whereby it could be exempt from the rule if there is a final permit and construction commences within a year of when the rule is published. The carbon pollution rule is expected to be published later in April.
“Plant Washington continues to lack a complete and legally effective permit that authorizes construction, and it won’t have one until the mercury permit amendment is issued, which will take another 30 days at least,” said Kurt Ebersbach, staff attorney with the Southern Environmental Law Center. “Based on filings by Power4Georgians in this case, it is clear that they have not done engineering, selected the boilers, lined up investors, or met any of the criteria that EPA is looking at to exempt a new source from complying with the carbon pollution rule.”
Power4Georgians is a consortium of four remaining electric membership cooperatives in Georgia, after six additional co-operatives left the consortium citing cost concerns. Cobb EMC, the largest and most prominent investor in P4G, withdrew funding and support for the consortium and the Plant Washington proposal in January of this year, leaving a very small base of ratepayers to shoulder the full $2.1+ billion cost of building the plant. Financial experts have questioned whether the current membership of Power4Georgians is sufficient to finance the plant’s construction.
“We’ve fought this plant from day one, because this major new source of air pollution will also guzzle up to 16 million gallons of water a day from our already stressed water resources,” said Katherine Helms Cummings, director of the Fall Line Alliance for a Clean Environment and Washington County resident. “It’s doubtful that Plant Washington will be built. The demand for electricity just isn’t there, and since the plant was announced over four years ago, cheaper electricity from natural gas and renewables is now readily available. Still, any proposed coal plant must do the maximum to reduce toxic pollution and risk to Georgians. Nothing less is acceptable.”
“Today’s agreement is great news for Georgia ratepayers, who will now avoid $2.3 billion in costs from Plant Ben Hill and reduce their monthly utility bill through new energy efficiency programs,” said Amelia Shenstone of the Southern Alliance for Clean Energy. “It also sends a message to those who continue to support Plant Washington: you can’t ignore the public health costs of dirty energy sources any more. We hope the remaining EMCs involved in Plant Washington will look into cleaner, cheaper ways to provide electricity to their members.”
The cancellation of Plant Ben Hill marks 168 total coal plant proposals cancelled across the U.S. due to changing market conditions, legal challenges and local opposition. In December 2011, New Jersey-based LS Power cancelled the Plant Longleaf coal plant proposal, which would have been built in Early County, Ga. Further, 106 coal plants have been scheduled for retirement, including two units at Plant Branch near Milledgeville that were recently approved by the Georgia Public Service Commission.
“The cancellation of Plant Ben Hill is just one more sign that coal is declining,” says Justine Thompson, attorney for GreenLaw that has been working with the community adjacent to the proposed Plant Ben Hill to oppose the construction of the plant. “Georgia has a promising future—but to be a serious player in the global economy while also ensuring that we have clean air and water, Georgia needs to embrace energy efficiency and more renewable sources of energy. We are now moving one step closer to that goal.”

Human actions have taken a steep toll on whales and dolphins. Some studies estimate that small whale abundance, which includes dolphins, has fallen 87% since 1980 and thousands of whales die from rope entanglement annually. But humans also cause less obvious harm. Researchers have found changes in the stress levels, reproductive health and respiratory health of these animals, but this valuable data is extremely hard to collect.

A Lot to Learn From Hormones<p>When sampling the blow, we are looking for hormones in mucus as these can be used to gauge psychological and physiological health. We are specifically interested in <a href="https://dx.doi.org/10.1371%2Fjournal.pone.0114062" target="_blank">hormones like cortisol</a> and <a href="https://doi.org/10.1016/j.ygcen.2018.04.003" target="_blank">progesterone</a>, which indicate stress levels and reproductive ability respectively, but can also help determine overall health.</p><p>Additionally, blow samples can detect <a href="https://dx.doi.org/10.1128%2FmSystems.00119-17" target="_blank">respiratory pathogens</a> in the lungs or nasal passages - blowholes evolved from noses after all.</p><p>This health analysis is especially important in areas with oil spills as the chemicals can cause hormonal problems that harm <a href="https://www.carmmha.org/investigating-how-oil-spills-affect-dolphins-and-whales/" target="_blank">development, metabolism and reproduction</a> in dolphins.</p><p>Hormone samples can provide scientists with valuable data, but collecting them from intelligent and unpredictable animals is challenging.</p>
Cetacean Collaborators<p>To build a drone that can stealthily collect spray from moving dolphins, we needed more data on their eyesight and hearing, and this is data that couldn't be collected in the wild nor simulated in a lab.</p><p>We worked with dolphins at facilities like Dolphin Quest in Bermuda, which provides guests opportunities to learn about dolphins while allowing <a href="https://dolphinquest.com/about-us/our-story/" target="_blank">scientists access to animals for noninvasive research</a>. Here the dolphins can swim away if they choose not to work with us, so we had to design the study like a game; the way a kindergarten teacher entertains a class. If the dolphins aren't interested, we don't get to do the science.</p><p>Over the course of hundreds of sessions, we sought to answer two questions: What can dolphins hear and what can they see around their heads?</p><p>To test dolphin hearing, we set up microphones and cameras to record dolphin behavior as we played drone noise in the air. We analyzed the responses to each noise – such as how many dolphins looked at the speaker – and used these as a proxy for their ability to hear the sounds.</p>

Robodolphin doesn't look like a real dolphin, but it doesn't need to in order to train our drone pilots. C.J. Barton / Oklahoma State University / CC BY-ND<p>To build robodolphin, we worked with dolphins trained to "chuff" or sneeze on command to measure spray characteristics. We used high-speed photography to see the dolphins' breath as it moved through the air. Then we conducted high resolution CT scans of a dolphin head and 3D-printed a replica of a nasal passage.</p><p>Now, we have a complete robodolphin and are tweaking its sprays to be nearly identical to the real thing. This will allow us to determine how close we need to get to collect the samples, and therefore, how quiet our drone needs to be.</p>

A Bit of Practice, Then Into the Wild<p>In the next few months, we will test flights over robodolphin with existing drones to determine the timing and strategy for collection. From there, we will fabricate a low-noise drone that can fly fast enough and with sufficient maneuverability to capture samples from wild dolphins. Like a video game, we will use the visual field data to develop approach trajectories to stay in the visual blindspots.</p><p>We plan to test our drones on a truck-mounted robodolphin moving down a runway, then using a boat to simulate realistic conditions. The next steps will involve ocean testing with dolphins trained for open ocean swimming. These tests will determine if our devices can catch and hold the hormones as the drone flies back to a researcher's boat.</p><p>Finally, we will deploy the system to collect data on wild dolphins. Our first goal is to test resident dolphins – animals that live on the coasts and deal directly with boat and oil industry noise – which will allow us to learn more about stress resulting from human impacts.</p><p>Those samples are a way off, but if all goes well we will have a specially built drone capable of flying long distances and capturing samples undetected in a few years. The samples collected will allow researchers to do better science with impact on the animals they study.</p>

Billions worth of valuable metals such as gold, silver and copper were dumped or burned last year as electronic waste produced globally jumped to a record 53.6 million tons (Mt), or 7.3 kilogram per person, a UN report showed on Thursday.
Environmental and Health Hazard<p>Experts say e-waste, which is now the world's fastest-growing domestic waste stream, poses serious environmental and health risks.</p><p>Simply throwing away electronic items without ensuring they get properly recycled leads to the loss of key materials such as iron, copper and gold, which can otherwise be recovered and used as primary raw materials to make new equipment, thereby reducing greenhouse gas emissions from extraction and refinement of raw materials.</p><p>Refrigerants found in electronic equipment such as fridge and air conditioners also contribute to global warming. A total of 98 Mt of CO2-equivalents, or about 0.3% of global energy-related emissions, were released into the atmosphere in 2019 from discarded refrigerators and ACs that were not recycled properly, the report said.</p><p>E-waste contains several toxic additives or hazardous substances, such as mercury and brominated flame retardants (BFR), and simply burning it or throwing it away could lead to serious health issues. Several studies have linked unregulated recycling of e-waste to adverse birth outcomes like stillbirth and premature birth, damages to the human brain or nervous system and in some cases hearing loss and heart troubles.</p><p>"Informal and improper e-waste recycling is a major emerging hazard silently affecting our health and that of future generations. One in four children are dying from avoidable environmental exposures," said Maria Neira, director of the Environment, Climate Change and Health Department at the World Health Organization. "One in four children could be saved, if we take action to protect their health and ensure a safe environment."</p>
Europe Leads the Way<p>While most of the e-waste was generated in Asia (24.9 Mt) in 2019, Europe led the charts on a per person basis with 16.2 kg per capita, the report said.</p><p>But the continent also recorded the <a href="https://www.dw.com/en/the-eu-declares-war-on-e-waste/a-51108790" target="_blank">highest documented formal e-waste collection and recycling</a> rate at 42.5%, still below its target of 65%. Europe was well ahead of the others on this front. Asia ranked second with 11.7%.</p><p>The authors said while more that 70% of the world's population was covered by some form of e-waste policy or laws, not much was being done toward implementation and enforcement of the regulations to encourage the take-up of a collection and recycling infrastructure due to lack of investment and political motivation.</p><p>"You have to think about new economic systems," said Kühr.</p><p>One approach could be that consumers no longer buy the products, but only the service they offer. The device would remain the property of the maker, who would then have an interest in offering his customers the best service and the necessary equipment. The maker would also be interested in designing his products in such a way that they are easier to repair and easier to recycle, Kühr said.</p>
