Book Description
Fly ash from the 527-MW Coal-fired Columbia Generating Station Unit I (Columbia Co., Wisconsin) is discharged as a slurry into an adjacent ashpit. Water from the ashpit is pumped to a ditch that joins the ashpit drain and Rocky Run Creek before they reach the Wisconsin River. Habitat alterations have been noted as relatively minor changes in water quality parameters (e.g., alkalinity, hardness, pH, and turbidity), as increased amounts of some dissolved trace elements (Cr, Ba, Al, Cd, and Cu), and as the precipitation of trace elements (Al, Ba, and Cr) into a floc that coats the stream bottoms. The ashpit drain became an unsuitable habitat for aquatic invertebrates after Columbia I began operating. Rocky Run Creek is still a suitable habitat for many aquatic invertebrates, but evidence of sublethal stresses and habitat avoidance exists.

Managing Coal Combustion Residues in Mines
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309100496
Category : Science
Languages : en
Pages : 273
Book Description
Burning coal in electric utility plants produces, in addition to power, residues that contain constituents which may be harmful to the environment. The management of large volumes of coal combustion residues (CCRs) is a challenge for utilities, because they must either place the CCRs in landfills, surface impoundments, or mines, or find alternative uses for the material. This study focuses on the placement of CCRs in active and abandoned coal mines. The committee believes that placement of CCRs in mines as part of the reclamation process may be a viable option for the disposal of this material as long as the placement is properly planned and carried out in a manner that avoids significant adverse environmental and health impacts. This report discusses a variety of steps that are involved in planning and managing the use of CCRs as minefills, including an integrated process of CCR characterization and site characterization, management and engineering design of placement activities, and design and implementation of monitoring to reduce the risk of contamination moving from the mine site to the ambient environment. Enforceable federal standards are needed for the disposal of CCRs in minefills to ensure that states have adequate, explicit authority and that they implement minimum safeguards.
