Last year, the EPA released an inventory of over 40 "high hazard potential" sites round the country that contain coal combustion residuals, that are commonly referred to as coal ash. This substance is a product of burning coal and is often stored in containment ponds or dams close to electrical utilities. As coal ash leaches into the soil and spills into areas surrounding these facilities, there can be serious ramifications on human and animal health, residential areas, and the environment. These storage ponds hold fly ash, bottom ash, coal slag, and flue gas residues that contain toxic metals like mercury, arsenic, selenium, cadmium, and lead-all probably toxic to people and wildlife.
Waste Generation
In step with the EPA's web site, "the coal combustion process generates ash equal to concerning 10 % of the initial volume of the coal. Regarding ninety five % of the ash is retained:
? Fly ash is entrained with hot flue gases, trapped by stack filters, and accounts for concerning 74% of the ash generated
? Bottom ash, too large or significant to be entrained, settles to the underside of the boiler and accounts for about twenty% of the ash generated
? Boiler slag, fashioned when the ash melts beneath the extreme heat, collects at the bottom of the boiler and in exhaust stack filters, and accounts for regarding half dozen% of the ash generated.
The common yearly generation of coal ash is about 61 million metric tons (MT). In 1990, the combustion of coal in utility and industrial boilers generated 61.six million MT of coal ash and slags and 17.2 million MT of sludges."*
Due to several recent coal ash spills, the EPA and other federal regulatory agencies are cracking down on the assessment, maintenance, and clean from coal ash storage ponds in the United States. These agencies can request info from facilities concerning their operations and then thoroughly review it to identify issues that need priority attention. Some agencies can conjointly visit several of these facilities to see if the management units are structurally sound. The prime 5 states that are home to those "high hazard potential" sites embrace: North Carolina, Arizona, Kentucky, Ohio, and West Virginia.
Though the risks related to hazardous coal ash sites can be devastating to the communities surrounding them, this is often a probability for our government to require a a lot of active role in making certain electrical (and different energy) utility sites are operating responsibly. This is conjointly a nice opportunity for insurance agents to help their purchasers-those who operate energy utilities along with contractors who might be employed to scrub them up-and create positive they have adequate environmental insurance. Take this chance to assist your insureds shield themselves from a potentially disastrous monetary loss and secure the longer term of their businesses and workforces.
