The document notes that “ This status has belike caused impounding of piss behind the collapse … In summation , other collapse within the workings may have occur creating additional water impounding conditions . ”

“ Conditions may exist that could result in a jamboree of the blockages and cause a release of large volumes of contaminated mine waters and deposit from inside the mine , which contain saturated threatening metals , ” the report says .

The EPA wascriticized for not instantly announcingthe fortuity to locals , which saw initial estimate derail from 1 million gallon of contaminated piddle to 3 million .
