&#147;<U>Company</U>&#148;), is filing materials contained in this Schedule 14A with the U.S. Securities and Exchange Commission (&#147;<U>SEC</U>&#148;) in connection with the solicitation of proxies from its stockholders in connection with its
2015 Annual Meeting of Stockholders and at any and all adjournments or postponements thereof (the &#147;<U>2015&nbsp;Annual Meeting</U>&#148;). Casella has not yet filed a preliminary or definitive proxy statement with the SEC in connection with its
solicitation of proxies to be used at the 2015 Annual Meeting. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>Press Release Issued by Casella on September&nbsp;1, 2015 </B></P>
<P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Attached hereto is a press release issued by Casella on September&nbsp;1, 2015 announcing the appointment of waste management industry veteran William P.
Hulligan to Casella&#146;s Board of Directors (the &#147;<U>Casella Board</U>&#148;) as well as the adoption by Casella of various corporate governance enhancements. The press release is being filed herewith because it may be deemed to be
solicitation material in respect of the potential solicitation of proxies to be used at the 2015 Annual Meeting. </P> <P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Appointment of William P. Hulligan
to the Casella Board of Directors </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Mr.&nbsp;Hulligan was appointed to the Casella Board effective September&nbsp;1, 2015. He is the former
President and Chief Operating Officer of Progressive Waste Solutions, one of North America&#146;s largest full-service waste management companies which provide non-hazardous solid waste collection, recycling and disposal services to commercial,
industrial, municipal and residential customers. Mr.&nbsp;Hulligan brings to the Casella Board more than 40 years of experience in the waste management industry, including a 24-year career at Waste Management, Inc., the largest provider of
comprehensive waste management services in North America. Following his time at Waste Management, Mr.&nbsp;Hulligan served seven years as Executive Vice President of Waste Services Inc., a publicly-traded multi-regional, integrated solid waste
services company, providing collection, transfer, landfill disposal and recycling services for commercial, industrial and residential customers in the United States and Canada. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Mr.&nbsp;Hulligan will replace current director James P. McManus as a Class III director who, following 10 years of dedicated service to Casella, has chosen
to retire from the Casella Board. As a Class III director, Mr.&nbsp;Hulligan will stand for election at the 2015 Annual Meeting. The Casella Board has determined that Mr.&nbsp;Hulligan is an &#147;independent director&#148; as defined under Rule
5605(a)(2) of the NASDAQ Marketplace Rules. In connection with his appointment to the Board, Mr.&nbsp;Hulligan was appointed to the Casella Board&#146;s Audit Committee. </P>
<P STYLE="margin-top:18pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B><I>Adoption of Corporate Governance Enhancements </I></B></P> <P STYLE="margin-top:6pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In
its press release, Casella also announced that the Casella Board had unanimously voted to approve a number of significant corporate governance enhancements. The corporate governance enhancements consist of the following actions: (i)&nbsp;the
adoption of a majority vote resignation policy for the election of directors in uncontested director elections, (ii)&nbsp;the adoption of stock ownership guidelines and a compensation clawback policy applicable to all executive officers who are
required to file reports pursuant to Section&nbsp;16 of the Securities Exchange Act of 1934, as amended, (iii)&nbsp;the adoption of a policy restricting any hedging and pledging activities with respect to Casella&#146;s securities, which is
contained within Casella&#146;s insider trading policy, (iv)&nbsp;the adoption of an amendment to Casella&#146;s 2006 Stock Incentive Plan to provide that the Casella Board may not cancel in exchange for a cash payment any outstanding option with an
exercise price per share above the then-current fair market value or take any other action under the Plan that constitutes a &#147;repricing&#148; within the meaning of the rules of the NASDAQ Stock Market, and (v)&nbsp;the adoption of a policy
providing that any new employment agreements to be entered into by Casella will not contain any provisions providing for gross-up payments for excise taxes paid under Section&nbsp;4999 of the Internal Revenue Code of 1986, as amended. Revised
Corporate Governance Guidelines are accessible on the corporate governance section of Casella&#146;s website, <U>www.casella.com</U>. </P>

<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman"><B>RUTLAND, VT., September&nbsp;1, 2015 &#150; </B>Casella Waste Systems, Inc. (Nasdaq: CWST) (&#147;<U>Casella</U>&#148; or the &#147;<U>Company</U>&#148;),
a regional solid waste, recycling, and resource management services company, today announced the appointment of waste management industry veteran, William P. Hulligan, to Casella&#146;s Board of Directors (the &#147;<U>Board</U>&#148;) effective
September&nbsp;1, 2015. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Mr.&nbsp;Hulligan is the former President and Chief Operating Officer of Progressive Waste Solutions, one of North America&#146;s
largest full-service waste management companies which provide non-hazardous solid waste collection, recycling and disposal services to commercial, industrial, municipal and residential customers. He brings to the Casella Board more than 40 years of
experience in the waste management industry, including a 24-year career at Waste Management, Inc., the largest provider of comprehensive waste management services in North America. During his tenure as Executive Vice President and President of Waste
Management&#146;s North American Solid Waste Division, annual revenue for Waste Management grew from approximately $1 billion to more than $6 billion. Following his time at Waste Management, Mr.&nbsp;Hulligan served seven years as Executive Vice
President of Waste Services Inc., a publicly-traded multi-regional, integrated solid waste services company, providing collection, transfer, landfill disposal and recycling services for commercial, industrial and residential customers in the United

appointment brings a tremendous amount of experience to our Board and his understanding of the waste industry, gained both as an executive officer and a public company board member, will greatly benefit Casella as we continue to move forward with
our strategic business plan.&#148; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">&#147;I am thrilled to serve on the Casella Board,&#148; said Mr.&nbsp;Hulligan. &#147;I have been involved in the
waste management industry for much of my life and have come to greatly admire Casella and its team. I have long believed that Casella has a unique opportunity in the waste management industry to drive growth and create value for stockholders and, as
such, I have closely followed Casella and currently own 100,000 shares of Casella stock, shares which I purchased never expecting that I would be offered the opportunity to join the Casella Board. I look forward to contributing my experience and
insight to the Casella Board in its efforts to bring Casella along the path of producing strong financial and strategic results.&#148; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Mr.&nbsp;Hulligan
will replace current director James P. McManus as a Class III director who, following ten years of dedicated service to Casella, has chosen to retire from the Casella Board. As a Class III director, Mr.&nbsp;Hulligan will stand for election at
Casella&#146;s 2015 Annual Meeting of Stockholders. The Casella Board has determined that Mr.&nbsp;Hulligan is an &#147;independent director&#148; as defined under Rule 5605(a)(2) of the NASDAQ Marketplace Rules. In connection with his appointment
to the Casella Board, Mr.&nbsp;Hulligan was appointed to the Board&#146;s Audit Committee. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Added Mr.&nbsp;Casella, &#147;On behalf of the entire Board
and management team, I would like to sincerely thank Jim McManus for his 10 years of dedicated service to our Board and the Company as a whole. Jim&#146;s counsel and contributions over the past decade have proven to be an extremely valuable asset
for Casella.&#148; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Today&#146;s announcement follows the appointment this past July of another waste management industry veteran, James E. O&#146;Connor,
to the Casella Board and reflects the Casella Board&#146;s continuing commitment to recruit new independent and highly-qualified directors that have perspectives, insights, experiences and competencies that expand the depth and breadth of the Board.

enhancements which we believe will serve the long-term interests of stockholders.&#148; </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The corporate governance enhancements consist of the following

option with an exercise price per share above the then-current fair market value or take any other action under the Plan that constitutes a &#147;repricing&#148; within the meaning of the rules of the NASDAQ Stock Market, and (v)&nbsp;the adoption
of a policy providing that any new employment agreements to be entered into by Casella will not contain any provisions providing for gross-up payments for excise taxes paid under Section&nbsp;4999 of the Internal Revenue Code of 1986, as amended.
