  • Legal lookout: competing coal ash proposals

    Depending upon comments the EPA gathers, industry may have to or not have to close out their coal ash containment ponds within five years. On May 4, 2010, EPA issued its long-awaited proposal to manage coal ash – the byproduct of burning coal to generate power. The agency proposed two quite different approaches for regulating coal ash, somewhat to the consternation of critics, who had hoped ...

  • Environment impact from ash disposal of the thermal power plant 'Kosova A'

    Mining activities impact on environment is as old as these activities themselves. It is estimated that thermal power plants in Kosova produce about 1.6 million tons of ash per year, and all ash produced is disposed as waste material. The main problems for environment pollution are the ash dumps containing more than 40 million tons of ash cover about 150 ha of land. The ash dumps sites of the ...

  • How toxic is coal ash? A laboratory toxicity case study

    Under a consent agreement among EPA and proponents both for and against stricter regulation, EPA is to issue a new coal ash disposal rule by the end of 2014. Laboratory toxicity investigations often yield conservative estimates of toxicity since many standard test species are more sensitive than resident species, thus could provide information useful to the rule‐making. However, few laboratory ...

  • Geochemical studies to delineate topsoil contamination around an ash pond of a coal-based thermal power plant in India

    In the present study, an attempt was made to delineate soil contamination around the ash pond of a coal-based thermal power plant. The topsoil in the study area was found to be contaminated to varying degrees from ash disposal. The soil drawn from various profiles was largely contaminated by ash fall out, predominantly in the prevalent wind direction. Pb, Zn, Cu, Ni, Co, Mn, Cr, V and Ba were ...

  • Selenium bioaccumulation in fish exposed to coal ash at the Tennessee Valley Authority Kingston spill site

    In December 2008, 4.1 million m3 of coal ash were released into the Emory and Clinch Rivers by the Tennessee Valley Authority (TVA) Kingston Fossil Plant. Coal ash contains several contaminants, including the bioaccumulative metalloid selenium (Se). Because Se is predominantly accumulated in aquatic organisms through dietary, rather than aqueous exposure, tissue‐based toxicity thresholds for ...

  • Coal-fired power on the way out?

    The past two years have witnessed the emergence of a powerful movement opposing the construction of new coal-fired power plants in the United States. Initially led by environmental groups, both national and local, it has since been joined by prominent national political leaders and many state governors. The principal reason for opposing coal plants is that they are changing the earth’s climate. ...

  • Review of coal as a promising source of lithium

    Coals are a major source of pollution in certain parts of the world due to mining, coal combustion, and disposal of fly ash. The recovery of valuable rare metals from coals or coal–processing byproducts is a promising way to utilise these traditional resources economically, efficiently and in an environmentally friendly way. Lithium, a highly interesting metal, has been found dispersed and even ...

  • Investigation of benefit of using coal wastes in cement production

    Waste disposal in coal preparation plants leads to serious environmental problems. These wastes usually contain about 20% carbon, and the composition of the remaining ash is similar to clay. Addition of these wastes to cement clinker raw material utilises carbon as a source of energy. In this investigation, the effect of addition of these waste materials to the raw materials used in cement ...

  • Inorganic contaminants attenuation in acid mine drainage by fly ash and its derivatives: column experiments

    Treatment of AMD with fly ash (FA) is a promising technology but solid residues (SR) generated in the process pose a disposal challenge. This study evaluates the suitability of the SR and SR, FA/ordinary Portland cement (OPC) blends for backfill in mine voids and in–situ treatment of AMD flows. The mitigation of AMD in a mine void was simulated by addition of simulated acid mine drainage ...

  • Application of Ecological Risk Assessment in Managing Residual Fly Ash in TVA's Watts Bar Reservoir, Tennessee

    The Tennessee Valley Authority conducted a Baseline Ecological Risk Assessment (BERA) for the Kingston Fossil Plant ash release site to evaluate potential effects of residual coal ash on biota in Watts Bar Reservoir, Tennessee. The BERA was in response to a release of 4.1 million m3 of coal ash on December 22, 2008. It used multiple lines of evidence to assess risks for 17 different ecological ...
