Ash Pond Remediation

To Energy Companies Coal Combustion Byproducts and ash ponds have always been a part of the coal plant process.  Decades ago, most coal ash ponds were constructed without liners, using low technology construction techniques.  Many were built in rural areas that today have become more developed and more environmentally sensitive.  Due to their age, recently several ash ponds and there accompanying infrastructure have failed causing property damage, environmental consequences and subsequent fines to the owner.

Today utilities are faced with remediation of ash ponds, discharge and storm water pipes.  Over time, the abrasiveness of the material flowing through the pipes causes wear and leakage.  Due to the complexity of many of these drainage systems, the coal ash byproduct can leak from pipes or into pipes, ultimately contaminating storm water, which is draining into a river.

Glenn Underwater Services engineers, fabricates and installs remote plugs to seal damaged coal ash discharge pipes.

With new EPA regulations pending, our company has been asked to inspect, repair, and abandon ash pond discharge pipes and riser structures at over 30 sites.  We have also been extensively involved in the abandonment of intake and other structures for decommissioning of existing fossil stations for various clients in the energy sector.
