60 Million Fish Dead/Year; New Permits now in place! GOOD NEWS

Saturday, November 20th, 2010

Recapping this article; The FirstEnergy’s Bay Shore plant kills more fish than all others in Ohio combined and is one of the largest sites for fish kills in the region. Bay Shore kills up to 46 million adults and 14 million juveniles a year whenoperating at full capacity & estimates 209 million fish eggs and 2.2 trillion microscopic fish in the larval form being pulled through screens and killed inside the plant each year.  What a shame, but permits now in place, should be at least better!

State EPA renews Bay Shore’s permit
Lower fish kills factor in decision

PhotoFirstEnergy Corp. is getting the chance to prove that its dual strategy for reducing fish kills at its Bay Shore power plant in Oregon will work.
The Ohio Environmental Protection Agency Friday announced it will renew the utility’s wastewater-discharge permit at the plant for 4 1/2 years, from Jan. 1 through July 31, 2015.

 The permit calls for the same reduction in fish kills that had been proposed in a draft document that went out for public comment last spring – at least 80 percent fewer impinged, or killed from being trapped against the plant’s intake screens, and at least 60 percent fewer entrained, or sucked through the hot plant by its powerful intake current.

The only difference between what was proposed and what was made final is that the deadline was moved up by 18 months, Ohio EPA spokesman Dana Pierce said, to April 1, 2013, instead of Oct. 1, 2014.
“Moving the date up will reduce two peak seasons of fish kills, which are highest during the April-to-June fish migration period,” the agency said in its news release.
The permit also provides FirstEnergy a variance from tougher federal rules for mercury releases into the water, giving the utility more time to phase in improvements.
Confronted by public outcry last spring, FirstEnergy said Friday it is pleased by the agency’s decision.
At an April 22 hearing, several area residents demanded the installation of a $100 million cooling tower.
Cooling towers greatly reduce water intake and reduce fish mortalities by 95 percent, making them the most effective devices at saving fish. But their price tag keeps them out of reach for many plants.
 The Bay Shore facility, built in 1955, is in a unique situation.
It sits in a modified estuary where the Maumee River meets western Lake Erie’s Maumee Bay, one of the Great Lakes region’s most valuable spawning areas. It kills more fish than all others in Ohio combined and is one of the largest sites for fish kills in the region.
 FirstEnergy’s consultant estimates that Bay Shore kills up to 46 million adults and 14 million juveniles a year when operating at full capacity.
More than half – 24 million emerald shiners and 14 million gizzard shad – are bait fish that support the Great Lakes region’s $7 billion fishery. About $1 billion of that economic impact is in Ohio alone.
 Records submitted by the utility also show an estimated 209 million fish eggs and 2.2 trillion microscopic fish in their larval form being pulled through screens and killed inside the plant each year.
Since last spring, FirstEnergy has announced scaled-back operations for three of the four units, saying the action was in response to the lackluster economy and less demand for industrial power, not because of fish.
 Prior to that, the utility installed several underwater shutterlike devices known as reverse louvers for a pilot study to see if they can be deployed on a larger scale to divert fish around the plant. The utility paid $500,000 to have enough installed for a two-year test run.
“Between the two of those, we will be able to meet the impingement and entrainment requirements,” said Mark Durbin, FirstEnergy spokesman. “Our focus all along has been on this system that we think will work, the louvers.”

Mercury Contamination in 96% of Wastewater Discharge Samples from Public Treatment Facilities (USGS)

High Mercury Levels Found in Water Throughout Indiana

USGS study shows that rain and wastewater discharges are sources

Mercury contamination in water and fish throughout Indiana has routinely exceeded levels recommended to protect people and wildlife, according to the U.S. Geological Survey (USGS). About 1 in 8 fish samples tested statewide had mercury that exceeded the recommended safety limit for human consumption. The causes include mercury in the rain and mercury going down the drain, according to a recently released federal study.

The most significant source of mercury to Indiana watersheds is fallout from the air. Much of the mercury in the air comes from human activity. In Indiana, coal-burning power plants emit more mercury to the air each year than any other human activity. In urban areas, wastewater discharge contributes a substantial portion of mercury to waterways.

These are among the key findings of a comprehensive study of mercury in the state’s watersheds during the past decade by the USGS in partnership with the Indiana Department of Environmental Management (IDEM).

“Indiana has been a national leader in understanding its mercury problems through a long-term statewide network of monitoring,” said USGS hydrologist Martin Risch, who led the study. “Actions by the IDEM provided data about mercury in fish and wastewater. Our understanding of mercury would not have been possible without their cooperation.”

During the study, scientists examined mercury in water, fish, precipitation, dry fallout and wastewater to determine the causes and effects of mercury moving through the environment. They also examined landscape characteristics, precipitation and streamflow for a total of more than 380,000 pieces of data that provide a snapshot of mercury in Indiana.

“The amount of mercury in precipitation was the main factor affecting mercury levels in the state’s watersheds,” said Risch. “But wastewater discharge can be a significant source of mercury. When wastewater is delivered to a stream from hundreds of discharge pipes, it increases mercury levels in watersheds more than was previously recognized.”

Mercury was detected in 96% of the wastewater discharge samples from public treatment facilities in this study. Mercury in wastewater samples typically exceeded criteria set to protect people and wildlife. Higher numbers of discharge pipes in a watershed were linked to higher levels of mercury in the streams.

Water draining from reservoirs in this study had significantly higher percentages of mercury converted to methylmercury than water from streams without dams. Dams can trap mercury transported by suspended particles in streams. Once the particulate mercury settles in the lake or reservoir behind the dam, natural processes change some of it to methylmercury, a toxin that accumulates in organisms throughout their lives. Methylmercury levels are amplified up the food chain and reach high levels in some sport fish and in fish that serve as food for wildlife.
