Dynegy awaits ok to stabilize river bank near coal ash ponds _ news-gazette. com

NEWTOWN — Dynegy Inc. P gasket 300tdi officials are awaiting governmental permission to stabilize an eroding bank where the Middle Fork River is carving away at the earth that holds back ponds full of coal ash left over from the company’s now-shuttered Vermilion Power Station.

According to Micah Hirschfield with Dynegy, the Houston-based energy company has received the go-ahead from other government agencies, like the U.S. Gas jet Army Corps of Engineers, that have recently been on site inspecting the ash ponds. Electricity notes physics But Dynegy is still awaiting approval from one last agency — the National Park Service — to do the stablization work. Hp gas online login The park service has jurisdiction, because the Middle Fork River was designated a national scenic waterway in 1989.

For years, river bank erosion in that area has been a concern of local citizens, the Prairie Rivers Network and others who fear possible failure of three man-made containment ponds adjacent to the river that hold ash from decades of burning coal at the former power plant. Grade 6 electricity The site is immediately upstream from Kickapoo State Park.

Coal ash can be harmful, because it contains a variety of heavy metals and minerals, including mercury, arsenic, selenium, chromium and cadmium. Electricity word search pdf Last year, Duke Energy was fined more than $100 million for a 2014 coal ash spill into North Carolina’s Dan River when a pipe collapsed under a coal ash dump, covering 70 miles of the river in gray sludge.

If slightly more than just 1 percent of the material stored in Dynegy Vermilion’s coal ash pits were to escape into the Middle Fork River, it would be equivalent to the volume that entered the Dan River in North Carolina, according to Lan and Pam Richart, of Champaign, co-founders of the nonprofit environmental advocacy organization called Eco-Justice Collaborative.

The Richarts have been sounding alarm bells, talking to various groups and officials throughout Vermilion County about what they believe is a serious threat to the Middle Fork River and local environment posed by the Dynegy ash ponds.

The Vermilion County Board has passed resolutions calling for protection of local resources from coal ash, and Vermilion Advantage, a membership group of local companies, businesses and other employers, is considering a similar resolution.

“We have a window of opportunity to address a serious concern that the public by and large doesn’t know about,” said Lan Richart, an ecologist, who with his wife, Pam, an environmental land use planner, owned a land use and environmental consulting firm in the Chicago suburbs for more than 20 years. Electricity generation The Richarts also believe that there are mine cavities below the Dynegy ponds.

“To be very clear, the ash berms (sides of the ponds) are not eroding, the river bank is eroding. Gas in oil lawn mower We do not have any concerns about the structural integrity of the ash ponds leading to any subsidence or collapse. Ortega y gasset obras completas Those ash ponds are stable,” Hirschfield said.

The company plans to install a liner over them and then an earthen layer. Static electricity in water The intent is to reduce the amount of water from rain or flooding that flows into the ponds, thereby protecting groundwater resources from leaching. Electricity and circuits class 6 cbse Only one of the three ponds has a liner at its bottom.

Hirschfield said the capping process would take two to three years, but the company is still waiting on that plan to be approved by the Illinois Environmental Protection Agency, which is currently in the process of writing new rules for the regulation of coal ash.

Environmental advocates do not support the cap-and-close plan and have been calling for Dynegy to remove the ash in the ponds altogether, arguing that the impoundments are in the river’s flood plain, and continual river erosion puts them at risk of failing altogether or leaching harmful elements into groundwater or the river.

“We think removal of material is certainly something that should be closely looked at,” Lan Richart said. Mp electricity bill payment online jabalpur He said there’s now precedent for total removal of the ash in Vermilion, because Duke Energy has started moving ash out of ponds in the Carolinas and disposing of it in an alternative way.

And Prairie Rivers and other environmental advocates maintain that groundwater monitoring done by the company has revealed that there’s groundwater contamination.

Hirschfield said, at some point, all three ponds have been monitored for groundwater contamination and if any groundwater is not in compliance now, it will be within 10 years per the company’s cap-and-close plan. Gas 47 cents But there’s no evidence of an effect on drinking water or groundwater, he added, and Dynegy is confident there’s no impact to private wells, because the nearest one is roughly half a mile from the edge of the company’s property.

Lan Richart said he doesn’t believe that the possible long-term risks of the cap-and-close plan have been sufficiently investigated. Electricity and circuits physics He said he assumes capping would reduce the amount of water going into the ponds and possible contamination leaching out, but it wouldn’t eliminate it entirely, nor would it eliminate long-term risks or maintenance issues.

Pam Richart said no matter what is done to shore up the river’s banks this year, the Middle Fork will continue flowing, requiring someone to be responsible for maintaining erosion control in the future if the coal ash isn’t moved out of the flood plain.

The Richarts have been speaking about this issue to groups throughout Vermilion County, and they believe it’s gaining more attention, especially as plans continue for riverfront development in downtown Danville along the Vermilion River, which the Middle Fork flows into upstream from Danville. Gas vs electric water heater savings The ash pits are 12 river miles from Danville, Pam Richart said.

Public education is important now, said Lan Richart, because there’s a window of opportunity to push for the cleanup of the material in the ash ponds rather than the cap-and-close plan. Gas vs electric oven efficiency If Dynegy’s plan is approved by the state, it’s permanent, he said. Gas in dogs symptoms The ecological impact and cost of a massive cleanup in the event of a future spill could become a liability for local taxpayers, he explained.

Hirschfield said registered professional engineers inspect the structural stability of the ponds annually, and Dynegy is not concerned about their stability.

Kim Biggs, spokeswoman with the Illinois EPA, said the stabilization work that Dynegy is planning will address the bank adjacent to what’s known as the New East Ash Pond. Electricity bill saudi electricity company That’s the newest of the three ponds and the one with a liner, but it is also the one closest to the river.

Biggs said the IEPA is holding off on Dynegy’s proposed groundwater management plan until after the bank stabilization is complete, because it may have repercussions for the management plan.

When speaking about this issue in the community, the Richarts show pictures they have taken of the river bank erosion that has exposed manmade material in the banks, which are stained an orange-red. Static electricity zap The Richarts and others argue that the orange-red is evidence of seeping from the ash ponds.

But Hirschfield said there are reddish-orange spots all along the Vermilion River, and they are naturally occurring. Electricity per kwh He said they are not only in the area around the power plant but all up and down the river on both sides.

“We take our commitments to the environment seriously,” he said, adding that Dynegy is committed to recycling — rather than impounding in ponds — 100 percent of the ash produced at its existing coal-burning plants by the year 2020.
