Beautiful location! photoshoot location,beautiful nature,refreshing ur moment in evening time.
Beautiful place. Good for fishing
Amazing place for family and friends not for Copple
An ash pond is an engineered structure used at fossil fuel power stations for the disposal of two types of coal combustion products: bottom ash and fly ash. The pond, also called a surface impoundment, uses gravity to settle out large particulates (measured as total suspended solids) from power plant wastewater. This technology does not treat dissolved pollutants. In the United States, federal design standards for ash ponds were strengthened in 2015, although various provisions of the new regulations are on hold as of 2019, pending ongoing litigation. Pond design Ash ponds are generally formed using a ring embankment to enclose the disposal site. The embankments are designed using similar design parameters as embankment dams, including zoned construction with clay cores. The design process is primarily focused on handling seepage and ensuring slope stability. Failure of a pond's earthen embankment can cause ash spills on adjacent land and rivers, with serious environmental damage, as evidenced in the 2008 Kingston Fossil Plant spill in Tennesseeand the 2014 Dan River coal ash spill in North Carolina. Disposal methods The wet disposal of ash into ash ponds is the most common ash disposal method,but other methods include dry disposal in landfills. Dry-handled ash is often recycled into useful building materials. Wet disposal has been preferred due to economic reasons, but increasing environmental concerns regarding leachate from ponds has decreased the popularity of wet disposal.The wet method consists of constructing a large "pond" and filling it with fly ash slurry, allowing the water to drain and evaporate from the fly ash over time. Leachate from fly ash can contain heavy metals in excess of allowable U.S. standards under the Resource Conservation and Recovery Act (RCRA).The flow of water through the fly ash and into ground water is controlled by using low-permeability clay layers and cutoff trenches/walls. Low-permeability clays have permeability on the order of 10-7 cm/s. Vertical flows through the foundation are controlled by siting fly ash ponds on areas of thick clay or rock layers that provide suitably low permeability through the base of the pond. Areas with high sub-surface permeability can be improved by importing suitable clay. Horizontal flows through the embankment are controlled using clay zones within the embankment. Cut off trenches and cut off walls are used to connect the embankment clay zones and the foundation clay layers. Cut off trenches are trenches that are dug into the selected low-permeability sub-surface layer and backfilled with clay to key the embankment clay zone into the sub-surface. Cut off trenches are generally used when the low permeability foundation layer(s) are near surface. Cut off walls are similar to cut off trenches, but are generally much deeper and narrower, and use either slurry or grout instead of clay. Environmental impacts In the United States, coal ash is a major component of the nation's industrial waste stream. In 2017, 38.2 million short tons (34.7x106 t) of fly ash, and 9.7 million short tons (8.8x106 t) of bottom ash were generated. Coal contains trace levels of arsenic, barium, beryllium, boron, cadmium, chromium, thallium, selenium, molybdenumand mercury, many of which are highly toxic to humans and other life. Coal ash, a product of combustion, concentrates these elements and can contaminate groundwater or surface waters if there are leaks from an ash pond.
