construction for each plant.
* According to the August 2006 DOE/EPA report “Coal Combustion Waste Management at Landfills and Surface Impoundments, 1994-2004” report nr. DOE/PI-
0004, 286 pp; http://www.ead.anl.gov/pub/dsp_detail.cfm?PubID=2008:
• 97% of newly constructed CCR landfills have groundwater monitoring (Table 14, p.35)
• 97% of newly constructed CCR landfills have liners (Table 13, p.33)
These percentages reflect a mix of state government permit requirements for some surveyed electricity plants, plus industry voluntary actions for other plants.
