HEATHER DUNCAN — hduncan@macon.com (The Telegraph) Posted: 9:47pm on Apr 15, 2012; Modified: 6:34am on April 16, 2012    • A power plant, cancer and a small town's fears • By John Sepulvado, CNN Radio • updated 9:12 AM, Sun April 1, 2012 • Posted on CNN.com CNN story hot air? State, Ga. Power react BY WILL DAVIS (Monroe County Reporter) Published: Wednesday, April 11, 2012 8:06 PM CDT

  19. Plant Scherer: Recent Media Attention • Background • February 17, 2012 (Friday): John Sepulvado, CNN interviewed a GPC media relations representative • Updated Article was posted to CNN.com on 4/1/2012 • CNN Article: A Power Plant, Cancer and a Small Town's Fears • Residents near Plant Scherer reporting a host of illnesses including cancer • Belief among a number of the residents that Plant Scherer is the cause • Uranium is implicated as a potential culprit • Other stakeholders to the table • The Sierra Club, The Environmental Integrity Project • US EPA, GA EPD, USGS, UGA

  20. Plant Scherer: Recent Media Attention • Implications from the news articles • There is a exceptionally high incidence of cancers and other illnesses in the area surrounding Plant Scherer. • There is no credible evidence supporting this assertion. • The Ga. Department of Public Health has initiated a scoping study to determine if additional investigation is necessary. • GPC is initiating the purchase of properties, demolishing the buildings, and sealing wells because it has something to hide. • GPC has stated it only makes offers on a case by case basis to individuals that have already put their properties up for sale. • Nearby properties are purchased as additional buffer and to provide space for expansion. • Structures on purchased properties with no potential use are demolished to avoid liability. • There is a Georgia regulatory requirement stating that abandoned or intended to be abandoned wells be sealed.

  21. Plant Scherer: Recent Media Attention • Implications from the news articles (cont.) • The Plant Scherer coal ash pond is the source of potential well water contamination • No previous tests have indicated a contamination problem. • Testing performed in April 2012 of four (4) Plant Scherer drinking water wells indicate no constituents which exceed EPA safe drinking water limits. • Some residents have reported high levels of uranium in their drinking water wells • The April 2012 test also included a test for uranium no onsite samples showed a detectable indication. • According to a news article, the Sierra Club helped arrange tests by the UGA School of Ecology on a dozen residential well samples near Plant Scherer and the preliminary results show few problems in the groundwater.

  22. Plant Scherer: Recent Media Attention • Implications from the news articles (cont.) • Dust from the Plant Scherer coal ash pond is making the nearby residents sick • There is no credible evidence supporting this to be the situation at Plant Scherer

  23. Plant Scherer: Recent Media Attention • What others are saying… • United States Environmental Protection Agency • Quoted as saying, “…they believed the contamination (uranium) to come from underneath a layer of granite 70 miles away near Atlanta.” • Georgia Environmental Protection Division (Jim Harden) • Quoted as saying, “…speculation is premature.” and “it (uranium) has always been determined to be naturally occurring in the earth.” • United States Geological Survey • USGS has researched the elements in coal ash and fly ash and has determined they do not register at levels that affect human health. • University of Georgia • UGA has previously documented naturally occurring uranium in drinking water wells in some parts of Monroe county, originating from granite bedrock
