        <footnote id="F1">The Form 3 filed on behalf of Mr. Coletta on December 12, 2012, noted an initial amount of 41,431 securities beneficially owned of Casella Waste Systems, Inc. (CWST) Class A Common Stock.  This amount should have been 34,290.  Therefore, this Form 3/A is being filed to clarify that the current amount of securities beneficially owned by Mr. Coletta of CWST Class A Common Stock is 95,492 shares, accounting for the initial 7,141 share discrepancy. The initial misstatement was also made on Form 4's filed by the reporting person after his original Form 3 was filed.</footnote>
