|James E. OConnor
Lead Director
Compensation Committee |  | 66 |  | Mr. OConnor has served as a member of our Board since July 2015. Mr. OConnor served as Chief Executive Officer of Republic Services, Inc., a publicly-traded non-hazardous solid waste collection, recycling and disposal
services company, from 1998 to 2011, and as Chairman of the Board of Republic Services from 2003 to 2011. Prior to joining Republic Services, Mr. OConnor spent close to 30 years at Waste Management, Inc., a provider of waste management
services, where he held various senior management positions. Mr. OConnor is a member of the Board of Directors of Clean Energy Fuels Corp., a publicly-traded provider of natural gas fuel for transportation in North America, where he serves on
the Compensation Committee and the Nominating and Corporate Governance Committee, and the Canadian National Railway Company, a publicly-traded rail transportation company, where he chairs the boards Strategic Planning Committee and also serves
on the Audit, Environmental & Safety and Finance Committees. Mr. OConnor holds a B.S. in Commerce (concentration in accounting) from DePaul University. We believe Mr. OConnor is qualified to serve on our Board due to his
over 40 years of experience in the waste management industry, including extensive public company leadership experience, as well as experience serving on the boards of directors of publicly-traded companies in a variety of industries, including waste
management, transportation and energy.

The holders of Class A common stock, voting separately as a class, are entitled to elect the Class A
Director. Mr. Peters, a Class II director and a member of the Compensation Committee, Audit Committee and Nominations and Governance Committee, serves as the Class A Director.

The employment agreement by and between us and Mr. John Casella requires that we use our best efforts to cause Mr. John Casella to
be nominated and elected as a director.

Code of Business Conduct and Ethics

We have adopted a written Code of Business Conduct and Ethics that applies to our directors, officers and employees, including our principal
executive officer, principal financial officer, principal accounting officer, and persons performing similar functions. We have posted a current copy of the Code of Business Conduct and Ethics on the Corporate Governance page of the Investor
Relations section of our website, www.casella.com. In addition, we intend to post on our website all disclosures that are required by law or NASDAQs listing standards concerning any amendments to, or waivers from, any provision of the
Code of Business Conduct and Ethics.

Director Nominations

No material changes have been made to the procedures by which security holders may recommend nominees to our Board.

Audit Committee

The current members of
the Audit Committee are Messrs. Callahan (Chair), Burke, Hulligan and Peters. Our Board has determined that each of Messrs. Callahan, Burke, Hulligan and Peters are independent as defined under the rules of NASDAQ, including the independence
requirements under Rule 10A-3 under the Exchange Act. Our Board has determined that Mr. Callahan is an audit committee financial expert as defined in Item 407(d)(5) of Regulation S-K.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and beneficial owners of more than 10% of our Class A common stock
to file with the SEC initial reports of ownership and reports of changes in ownership of our Class A common stock and other equity securities. Based solely on a review of copies of reports filed pursuant to Section 16(a) and representations made by
persons required to file such reports, we believe that during fiscal 2015, our officers, directors and greater than 10% beneficial owners timely filed all reports they were required to file under Section 16(a), with the exception of late Form 4
filings reporting a grant of restricted Class A common stock to each of Messrs. Burke and Callahan, filed with the SEC on November 25, 2015, and a late Form 4 filing reporting the grant of a stock option award to purchase shares of Class A common
stock to Edmond R. Coletta, our Senior Vice President and Chief Financial Officer, filed with the SEC on November 25, 2015.

|-------- | ----------------------

Compensation Discussion and Analysis

This Compensation Discussion and Analysis is designed to provide our stockholders with an understanding of our executive compensation
philosophy, objectives, program and process, as well as the compensation paid to our named executive officers in fiscal 2015 and the changes the Compensation Committee has implemented for the year ending December 31, 2016, or fiscal 2016. For fiscal
2015, our named executive officers were:



| |  |  | John W. Casella, our Chief Executive Officer and Chairman of our Board;
| | - |  | -----------------------------------------------------------------------



| |  |  | Edmond R. Coletta, our Senior Vice President and Chief Financial Officer;
| | - |  | -------------------------------------------------------------------------



| |  |  | Edwin D. Johnson, our President and Chief Operating Officer;
| | - |  | ------------------------------------------------------------



| |  |  | David L. Schmitt, our Senior Vice President and General Counsel; and
| | - |  | --------------------------------------------------------------------



| |  |  | Christopher B. Heald, our Vice President of Finance and Chief Accounting Officer.
| | - |  | ---------------------------------------------------------------------------------

Objectives and
Philosophy of Our Executive Compensation Program

The Compensation Committee seeks to achieve the following broad objectives in
connection with our executive compensation program:



| |  |  | Attract, retain and incentivize qualified and talented executives by providing compensation opportunities comparable to those offered by other companies with which we compete for business and talent;
| | - |  | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Reward achievement of our short-term and long-term business objectives, while discouraging excessive risk-taking behavior;
| | - |  | --------------------------------------------------------------------------------------------------------------------------



| |  |  | Ensure that executive compensation is aligned with our corporate strategies, business objectives and the long-term interests of our stockholders; and
| | - |  | -----------------------------------------------------------------------------------------------------------------------------------------------------



| |  |  | Closely align the long-term interests of our executives with those of our stockholders by providing equity incentives that link a portion of the executives compensation with the future performance of our Class A
common stock.
| | - |  | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Roles of Our Compensation Committee and Compensation Committee Consultant

The Compensation Committee is responsible for overseeing our executive compensation program. In this capacity, the Compensation Committee
designs, implements, reviews and approves annually all compensation for our named executive officers. In the performance of its duties, the Compensation Committee periodically reviews the total compensation, including the base salary, annual
incentive compensation opportunities, long-term incentive award opportunities and other benefits for each of our named executive officers. In the first quarter of each year, the Compensation Committee meets to determine base salary increases,
if any, for our named executive officers; confirm the results of our performance for purposes of the annual incentive compensation awards; approve strategic and business objectives, which include the performance measures and goals for the annual
incentive compensation plan; review the annual incentive compensation targets for the current year; and approve the form, amount, dollar value and vesting criteria for equity awards.

The Compensation Committee has the authority to retain compensation consultants and other outside advisors to assist in the evaluation of
executive officer compensation. During fiscal 2015, the Compensation Committee retained an independent compensation consultant, Arthur J. Gallagher & Co.s Compensation Consulting Practice, or Gallagher Compensation Consulting. Gallagher
Compensation Consulting was retained to assist the Compensation Committee with its review of the fiscal 2015 executive compensation program and recommendations for the fiscal 2016 executive compensation program and reports directly to the
Compensation Committee. During fiscal 2015, Gallagher Compensation Consulting advised the Compensation Committee on a variety of subjects, including compensation plan design and trends, pay-for-performance analytics, peer group benchmarking and
other related matters. During fiscal 2015, we retained Gallagher Benefit Services, Inc., a subsidiary of Arthur J. Gallagher & Co., to provide us with insurance brokerage and benefit plan advisory services. The primary representative of
Gallagher Compensation Consulting that advised the Compensation Committee in fiscal 2015 did not participate in the provision of these other services performed by Gallagher Benefit Services, Inc. Management directly engaged Gallagher Benefit
Services, Inc., and the Compensation Committee had no role in selecting or approving them for the services performed.

##### Table of Contents

In making executive compensation decisions for fiscal 2015 and fiscal 2016, the Compensation
Committee analyzed a number of factors, including the compensation data provided by Gallagher Compensation Consulting from independent commercially available salary surveys published by Towers Watson and Mercer LLC and other sources, which included
publicly available compensation information from our industry and other industries. Data was generally gathered from this independent market data based on the size of the organization (measured in revenue) and type of organization, and where
possible, the data was targeted to our revenue level using regression analysis. The Compensation Committee also reviewed compensation programs of a peer group of publicly traded companies in the waste management industry, as provided by Gallagher
Compensation Consulting. While we do not consider their compensation programs to be directly comparable to ours due to the larger size of those companies, we do review their programs to understand how relevant peers in our industry align
performance-based compensation to key operating and financial metrics. This peer group, which is periodically reviewed and updated by the Compensation Committee after consultation with Gallagher Compensation Consulting, consists of Covanta Holding
Corporation, Progressive Waste Solutions Ltd., Republic Services, Inc., Waste Connections, Inc. and Waste Management, Inc. The Compensation Committee also relies on various other factors, including our long-term plan, existing compensation paid to
executive officers, experience level of the individual, market factors, general economic conditions, corporate performance and cost of living in the areas where our executive officers live.

Say-on-Pay Feedback from Stockholders

The Compensation Committee carefully considers feedback received from shareholders on compensation for our named executive officers. At
our 2015 Annual Meeting of Stockholders, or 2015 Annual Meeting, we submitted our executive compensation program to an advisory vote of our stockholders and it received the support of 97% of the total votes cast. Annually, the Compensation Committee
intends to review the results of the advisory vote and will consider this feedback as it completes its annual review of each pay element and the total compensation packages for our named executive officers with respect to the next fiscal year.

Components of our Executive Compensation Program

Fiscal 2015 Executive Compensation Program

In fiscal 2015, the primary elements of our executive compensation program were:



| |  |  | base salary;
| | - |  | ------------



| |  |  | annual cash incentive compensation;
| | - |  | -----------------------------------



| |  |  | discretionary bonuses;
| | - |  | ----------------------



| |  |  | long-term incentives; and
| | - |  | -------------------------



| |  |  | severance and change-of-control benefits.
| | - |  | -----------------------------------------

Base Salary

On an annual basis, our Compensation Committee reviews and evaluates for adjustment the base salaries of our named executive officers based on
the scope of each executives responsibilities, individual contribution, prior experience and sustained performance. Base salaries are also reviewed and adjusted, as deemed appropriate, in the case of promotions or other significant changes in
responsibility. No formulaic base salary increases are provided to our named executive officers, and none of our named executive officers is currently party to an employment agreement that provides for automatic or scheduled increases in base
salary. In making decisions regarding salary increases, the Compensation Committee may also draw on the experiences of members of our Board with other companies and the peer group compensation data reviewed by the Compensation Committee. After
taking into consideration such factors, the Compensation Committee approved a 2.0% increase the annual base salaries of our named executive officers for fiscal 2015.

Annual Cash Incentives

Fiscal 2015 Annual Cash Incentive Compensation

In January 2015, the Compensation Committee approved the annual incentive compensation plan for fiscal 2015, pursuant to which our named
executive officers were eligible to receive incentive compensation with respect to fiscal 2015, payable in cash or equity, as determined by our Compensation Committee, based upon the improvement of EVA in fiscal 2015 compared to EVA in the twelve
months ended December 31, 2014, or calendar 2014. EVA is calculated as operating income, adjusted for certain items, less a cost of capital charge, with the cost of capital charge calculated as our weighted average cost of capital applied to our
consolidated net fixed assets. As defined by the plan, the Compensation Committee would allocate positive year-over-year EVA improvement to the annual incentive pool for our named executive officers as follows: 7.5% of such positive year-over-year
improvement that is less than or equal to $5.6 million if EVA increases year-over-year for fiscal 2015 as compared to calendar 2014; 15% of such incremental positive year-over-year EVA improvement that is greater than $5.6 million but less than or
equal to $9.1 million if EVA increases over $5.6 million year-over-year; and 30% of such incremental positive year-over-year EVA improvement that is greater than $9.1 million if EVA increases over $9.1 million year-over-year. If EVA decreases
year-over-year, then no EVA improvement would be allocated to the annual incentive pool. If we were not in compliance with financial covenants under our senior secured asset-based revolving credit facility before or after accruing for bonus awards
as determined by the fiscal 2015 bonus plan, then the Board would have the discretion to reduce the annual incentive compensation payouts to ensure compliance with such financial covenants.

Amounts payable under the annual incentive compensation plan to the named executive officers were calculated as a percentage, from zero to
100%, of a maximum bonus amount, which is based on a percentage of the applicable executives base salary. The following table shows the fiscal 2015 maximum annual incentive bonus amount calculated as a percentage of the annual base salary for
which each of Messrs. John Casella, Coletta, Johnson, Schmitt and Heald was eligible.

##### Table of Contents

In March 2016, the Compensation Committee approved the payout of annual incentive compensation to
our named executive officers under the fiscal 2015 incentive compensation plan based upon the achievement of increased EVA when compared to calendar 2014. The period-over-period increase in EVA for calendar 2014 to fiscal 2015 was $9,315,247. As
defined by the plan, the Compensation Committee allocated 10.8% of such positive year-over-year EVA improvement to the annual incentive bonus pool for our named executive officers. Based on such allocation, the annual cash incentive compensation
awarded under the fiscal 2015 incentive compensation plan was calculated at 73.8% of the fiscal 2015 maximum annual incentive compensation amount for each named executive officer and awarded by the Compensation Committee as follows: $406,695 for Mr.
John Casella, $167,601 for Mr. Coletta, $243,264 for Mr. Johnson, $122,350 for Mr. Schmitt and $69,665 for Mr. Heald.

Discretionary
Bonuses

In October 2014, the Compensation Committee approved a special bonus plan for members of our finance team, including Messrs.
Coletta and Heald, relating to certain proposed financing transactions, including the refinancing of our senior secured credit facility. Pursuant to such bonus plan, Mr. Coletta was eligible to receive a bonus payment upon the closing of each of
four specified financing transactions for a total bonus payout of $202,055 and Mr. Heald was eligible to receive a bonus payment upon the closing of each of two specified financing transactions for a total bonus payout of $85,250. Two of the
transactions closed during transition period 2014, and the remaining other two transactions closed in fiscal 2015. Mr. Coletta received a bonus payout of $202,055, of which $44,100 was earned during transition period 2014 and $157,955 was earned
during fiscal 2015. Mr. Heald received a bonus payout of $85,250, all of which was earned in fiscal 2015.

Long-Term Incentives

Our named executive officers are also eligible to receive equity awards under our stock incentive plans. We typically make equity
awards to our officers and employees as an incentive to enhance long-term shareholder value. Equity awards are typically granted when the person is first hired, receives a promotion or other significant change in responsibility, and thereafter once
annually as a part of our broader equity incentive program at a regularly scheduled Compensation Committee meeting early in the commencement of the respective fiscal year.

In fiscal 2015, we granted restricted stock units, or RSUs, each of which represents the right to receive a share of our Class A common stock,
to our named executive officers that vest based on continued employment in three equal annual installments beginning on the first anniversary of the date of grant. The RSUs will vest in full upon a change of control of the Company.

Changes Implemented in 2016 to Further Align Pay with Performance

In March 2016, the Compensation Committee implemented several changes to our executive compensation program for fiscal 2016, including the
adoption by the Compensation Committee of the Non-Equity Incentive Plan as described further below. As part of its comprehensive annual review process, the Compensation Committee considered feedback received from stockholders, data provided by the
Compensation Committees independent compensation consultant, and alignment of the executive compensation program to our fiscal 2016 operating plan and budget, or Fiscal 2016 Operating Plan, and our financial plan for the fiscal year ending
December 31, 2018, or Fiscal 2018 Plan.

In implementing such changes to the executive compensation program for fiscal 2016, the goal
of the Compensation Committee was to further align the compensation of our executive officers with stockholders interests, to directly link compensation to the achievement of company performance goals and to appropriately balance
fixed and performance-based compensation. Further, while the percentage of the total compensation of each executive officer that is comprised of each component of our executive compensation program is not specifically fixed,
the Compensation Committee has targeted total target cash compensation (base salary and annual cash incentive compensation) of our executive officers closer to the 50th percentile of the market
data provided by the Compensation Committees independent compensation consultant by increasing the total target annual cash incentive compensation for certain executive officers.

##### Table of Contents

While the Compensation Committee approved the majority of its planned changes to our executive
compensation program in March 2016, the planned updates to long-term incentive compensation for our executive officers will only be implemented after we receive stockholder approval for our new stock incentive plan at our 2016 Annual Meeting of
Stockholders. The Compensation Committee plans to shift long-term incentive compensation from the current program that only includes time-vested RSUs, to a new program that includes up to 75% in the form of performance-based stock units, or PSUs,
and 25% of long-term incentive compensation in the form of time-vested RSUs. PSUs are expected to be granted to our executive officers if stockholder approval of our new stock incentive plan is obtained, and such PSUs are expected to vest based upon
our achievement of Free Cash Flow and Adjusted EBITDA targets that will be established based on the Fiscal 2018 Plan. Further, we intend to use Relative Total Shareholder Returns, or RTSR, as a multiplier to scale achievement of the PSU targets
based upon the relative returns of our stock performance in relation to the Russell 2000 Index.

Non-Equity Incentive Plan and Fiscal
2016 Annual Cash Incentive Compensation

The Non-Equity Incentive Plan formalizes our annual incentive compensation program for our
executive officers and provides for the payment of incentive compensation to executive officers for their contributions to the Company based on achievement of pre-determined corporate performance goals. The Non-Equity Incentive Plan provides
for awards payable in cash or, to the extent permissible under a shareholder-approved stock plan of the Company, stock-based awards to our executive officers. Pursuant to the terms of the Non-Equity Incentive Plan, participants are granted
awards that are earned at the end of a specified performance period, subject to the achievement of performance goals established by the Compensation Committee that are based on any one or more of the performance measures set forth in the plan,
subject to certain adjustments as specified by the Compensation Committee pursuant to the plan.

Annual incentive compensation for fiscal
2016 will be paid to our executive officers pursuant to the Non-Equity Incentive Plan. The Compensation Committee determined that each of the Companys executive officers will have an opportunity to earn annual incentive compensation for fiscal
2016 based on a percentage of annual base salary. In order to bring total target cash compensation (base salary and annual cash incentive compensation) of our named executive officers closer to the
50th percentile of the market data provided by the Compensation Committees independent compensation consultant, the Compensation Committee approved increases to the target annual cash
incentive compensation opportunity for our named executive officers. After giving effect to said increases, the target annual cash incentive compensation opportunity of each named executive officer, which such target amounts are based upon the
following percentage of the respective officers annual base salary, are as follows: Mr. Casella: 150%; Mr. Johnson: 85%; Mr. Coletta: 85%; Mr. Schmitt: 75%; and Mr. Heald: 50%.

The Compensation Committee established performance measures and specific performance goals pursuant to the Non-Equity Incentive Plan that are
based on the Fiscal 2016 Operating Plan. Annual incentive compensation will be paid based on the degree of achievement against the specific performance goals following the end of fiscal 2016. All of our named executive officers were assigned
the same performance measures and weightings in recognition of their shared responsibility for overall corporate financial performance.

The performance measures and weighting for the fiscal 2016 annual incentive compensation are as follows:



|                           |  |                                                 |    |   |                |  |    |  
|-------------------------- |  | ----------------------------------------------- | -- | - | -------------- |  | -- | -
|                           |  | Fiscal 2016 Performance Measures and Weightings |   
|                           |  | Adjusted Operating Income                       |    |   | Free Cash Flow | 
|For All Executive Officers |  |                                                 | 50 | % |                |  | 50 | %

The Compensation Committee evaluated key financial measures and identified Adjusted Operating Income and Free
Cash Flow, both non-GAAP measures, as appropriate drivers of performance under the Non-Equity Incentive Plan for fiscal 2016. Adjusted Operating Income is calculated as earnings before interest, taxes, adjusted for gains or losses on assets
sales or divestiture transactions; development project charge write-offs; legal, contract or tax settlement costs; bargain purchase gains; asset or goodwill impairment charges; environmental remediation charges; severance and reorganization costs;
expenses from divestiture, acquisition and financing transactions; gains on the settlement of acquisition related contingent consideration; fiscal year-end transition costs; proxy contest costs; losses on the abandonment or the closure and
discontinuation of operations, subject to certain adjustments as specified by the Compensation Committee pursuant to the Non-Equity Incentive Plan. Free Cash Flow is calculated as net cash provided by operating activities, less capital expenditures
(excluding acquisition and rail infrastructure related capital expenditures), less payments on landfill operating lease contracts, plus proceeds from divestiture transactions, plus proceeds from the sale of property and equipment, plus proceeds from
property insurance settlement, less contributions from (distributions to) noncontrolling interest holders, subject to certain adjustments as specified by the Compensation Committee pursuant to the Non-Equity Incentive Plan.

##### Table of Contents

Each performance goal has a performance range built around it, with a commensurate increase or
decrease in the associated annual incentive compensation opportunity. The range of performance goals and associated incentive compensation opportunities under the Non-Equity Incentive Plan for fiscal 2016 is expressed in the form of
minimum, threshold, target and maximum achievement levels. For fiscal 2016, subject to Free Cash Flow exceeding a certain threshold amount, if the minimum achievement level of a performance
measure is not met, no incentive compensation payment will be paid to an executive officer with respect to such performance measure component; if the threshold achievement level is met for a performance measure, 50% of the executive
officers target incentive compensation amount will be multiplied against the 50% weighting of such performance measure component; if the target achievement level is met for a performance measure, 100% of the executive
officers target incentive compensation amount will be multiplied against the 50% weighting of such performance measure component; and if the maximum achievement level is met for a performance measure, 200% of the executive
officers target incentive compensation amount will be multiplied against the 50% weighting of such performance measure component. Between each of the achievement levels, results will be interpolated within each achievement level to calculate
specific annual incentive compensation award percentages.

If Free Cash Flow for fiscal 2016 does not exceed a certain threshold amount,
no annual incentive compensation will be paid to the executive officers under the Non-Equity Incentive Plan for fiscal 2016 even if achievement of the Adjusted Operating Income performance goal would have resulted in payment of the annual incentive
compensation.

Benefits and Other Compensation

We maintain broad based benefits that are provided to all employees, including health and dental insurance, life and disability insurance and a
401(k) plan. Our executive officers are eligible to participate in all of our employee benefit plans, in each case, on the same basis as other employees.

Severance and Change-of-Control Benefits

Pursuant to employment agreements we have entered into with our named executive officers, each such named executive officer is entitled to
specified benefits in the event of the termination of his employment under specified circumstances, including termination following a change of control of the Company. We have provided more detailed information about these benefits, along with
estimates of their value under various circumstances, under the caption Potential Payments Upon Termination or Change of Control below.

Compliance with Internal Revenue Code Section 162(m)

Section 162(m) of the Internal Revenue Code of 1986, as amended, or the Code, generally disallows a tax deduction for compensation in excess of
$1.0 million paid to a companys chief executive officer and its three other officers (other than the chief financial officer) whose compensation is required to be reported to our stockholders pursuant to the Exchange Act by reason of being
among our most highly paid executive officers. Certain compensation, including qualified performance based compensation, is not subject to the deduction limitation if certain requirements are met. The Compensation Committee reviews the potential
effect of Section 162(m) periodically and uses its judgment to authorize compensation payments that may be in excess of the limit when it believes such payments are appropriate and in the best interests of our stockholders, after taking into
consideration changing business conditions and the performance of our employees.

|(1) | The transition period salary amounts included in the Summary Compensation Table differ from those in the annual base salary table on page 8 because transition period 2014 is eight months and because, in some instances,
salary increases were effected during each of the periods presented on a non-retroactive basis.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(2) | Amounts shown in this column reflect the aggregate grant date fair value of the restricted stock units and performance-based restricted stock units rewarded as a part of our broader annual equity incentive program under
our 2006 Stock Incentive Plan, computed in accordance with Financial Accounting Standards Board, or FASB, Accounting Standards Codification, or ASC, Topic 718. Stock award compensation is based upon the last reported sales price of our Class A
common stock on the NASDAQ Stock Market on the grant date.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(3) | Reflects the aggregate grant date fair value for stock option awards granted under our 2006 Stock Incentive Plan in accordance with FASB ASC Topic 718. The assumptions used to calculate the value of stock option awards
are set forth in Note 11 to our Consolidated Financial Statements included in the Original Form 10-K.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|(4) | The amounts reported in this column reflect amounts earned under the annual incentive bonus plan, except for as follows: the transition period 2014 and fiscal 2015 amounts reported in this column for Mr. Coletta
include $44,100 and $157,955 earned under the special bonus plan for transition period 2014 and fiscal 2015, respectively, and the fiscal year 2015 amount reported in this column for Mr. Heald includes $85,250 earned under the special bonus plan for

Potential Payments Upon Termination or Change of Control

Employment Agreements

We have employment agreements with Messrs. John Casella, Johnson, Coletta, Schmitt and Heald, which we entered into as follows: Mr. John
Casella: December 8, 1999; Mr. Johnson: July 6, 2010; Mr. Coletta: September 1, 2012; Mr. Schmitt: May 31, 2006; and Mr. Heald: March 1, 2016. Each of Messrs. John Casellas and Johnsons employment
agreement has an initial term of three years and is automatically renewable for additional one-year terms thereafter unless terminated by either party pursuant to the terms of the agreement. Each of Messrs. Colettas, Schmitts and
Healds employment agreement has an initial term of one year and is automatically renewable for additional one-year terms thereafter unless terminated by either party pursuant to the terms of the agreement. In December 2008, we amended our
employment agreements with Messrs. John Casella and Schmitt to document compliance with, and, as applicable, exemption from, Section 409A of the Code.

Pursuant to the terms of their employment agreements, each of Messrs. John Casella, Johnson, Coletta, Schmitt and Heald is entitled to a
specified annual base salary, subject to adjustment as set forth in the agreement, an annual bonus consisting of cash, stock awards or a combination of cash and stock awards, in an amount determined by the Compensation Committee each fiscal year,
and a severance package upon the termination of employment. The base salary and bonus components of their compensation are described above under Compensation Discussion and Analysis  Components of our Executive Compensation Program
 Base Salary and Compensation Discussion and Analysis  Components of our Executive Compensation Program  Annual Incentive Bonus.

Mr. John Casella has agreed not to compete with us for a period of two years after the termination of his employment within 300 miles of
any facility operated by us during the term of his employment and not to solicit our customers, accounts or employees for a period of two years after the termination of his employment. Each of Messrs. Johnson, Coletta, Schmitt and Heald has agreed
not to compete with us for a period of one year after the termination of his employment within 100 miles of any facility operated by us during the term of his employment and not to solicit our customers, accounts or employees for a period of one
year after the termination of his employment. In the event that Mr. John Casella terminates his employment voluntarily and is not entitled to severance, the non-compete provisions of his agreement would not apply unless we continue to pay his
base salary and any termination benefits or payments required under his agreement.

In the event Mr. John Casellas employment
is terminated by us other than for cause (as defined below), he will be entitled to payment of an amount equal to (a) three times the sum of (i) the highest annual base salary paid to him at any time prior to his termination and (ii) the
higher of the most recent bonus paid to him at any time prior to his termination or 50% of his annual base salary immediately prior to such termination, plus (b) an amount in cash equal to the value of any accrued but unpaid or unused, as

applicable, base salary, bonus and vacation. In addition, Mr. John Casella will continue to receive healthcare and other benefits for a period of three years from the date of termination,
and any equity grants issued by us to him will become vested in full upon termination without cause. In the event that Mr. John Casella terminates his employment with us for good reason or qualified good reason (as defined below), he will
receive the severance payments and benefits described in the preceding two sentences plus an additional payment intended to compensate him for excise taxes under Section 4999 of the Code payable in connection with the severance payments and
benefits. For the purposes of Mr. John Casellas employment agreement, good reason means the occurrence of (a) a change of control, accompanied by, or followed within the 12-month period after a change of control by (b)(i)
the assignment to the employee of any duties inconsistent with his status prior to the change of control, (ii) a material adverse alteration in the nature or status of the employees responsibilities from those provided in the agreement or
the transfer of a significant portion of such responsibilities to one or more other persons, (iii) a material diminution in his base compensation or (iv) a material change in the geographic location at which he must perform services for us. For
the purposes of Mr. John Casellas employment agreement, qualified good reason means the occurrence of one of the events under clause (b)(i), (ii) or (iii) of the preceding definition of good reason. In the event Mr.
John Casellas employment is terminated upon his death, his written designee, spouse or estate, as applicable, will be entitled to the severance payments described in the first sentence of this paragraph as well as healthcare and other benefits
for a period of one year from the date of death. In the event Mr. John Casellas employment is terminated by us for disability, he will be entitled to the severance payments described in the first sentence of this paragraph as well as
healthcare and other benefits for a period of one year from the date of such termination.

will continue to receive healthcare and other benefits for a period of two years from the date of termination. Any stock options or equity grants issued by us to Mr. Johnson will become exercisable or vested in full upon termination without
cause. In the event that Mr. Johnson terminates his employment with us for good reason, defined as the assignment of any duties inconsistent with his status as President and Chief Operating Officer, a material adverse alteration in the nature

as Senior Vice President and General Counsel, a material adverse alteration in the nature or status of his responsibilities from those provided in the agreement or the transfer of a significant
portion of such responsibilities to one or more other persons, or a material diminution in his base compensation, Mr. Schmitt will be entitled to receive the severance payments and benefits described in the preceding three sentences plus an
additional payment intended to compensate him for excise taxes under Section 4999 of the Code payable in connection with the severance payments and benefits. In the event Mr. Schmitts employment is terminated upon his death, his written
designee, spouse or estate, as applicable, will be entitled to the payments described in the first sentence of this paragraph. In the event Mr. Schmitts employment is terminated by us for disability, he will be entitled to the severance
payments and benefits described in the first two sentences of this paragraph.

In the event Mr. Healds employment is terminated
by us without cause or by reason, he will be entitled to payment of an amount equal to (a) the sum of (i) the highest annual base salary paid to him at any time prior to such termination and (ii) his target annual cash incentive
compensation opportunity under the Non-Equity Incentive Plan for the fiscal year in which such termination occurs and (b) an amount in cash equal to any accrued but unpaid or unused, applicable, base salary and vacation and a bonus relating to
the prior fiscal year which, as of the date of termination, has been determined by us pursuant to his agreement but not yet paid prior to the date of termination. In addition, Mr. Heald will continue to receive healthcare benefits for a period
of one year from the date of termination. Any stock options or equity grants issued by us to Mr. Heald will become exercisable or vested in full upon termination without cause. In the event that Mr. Heald terminates his employment for good
reason, defined as the assignment of any duties inconsistent with his status as Vice President and Chief Accounting Officer, a material adverse alteration in the nature or status of his responsibilities from those provided in the agreement or the
transfer of a significant portion of such responsibilities to one or more other persons, a material diminution in his base compensation, or a material change in the geographic location at which he must perform services for us, Mr. Heald will be
entitled to receive the severance payments and benefits described in the preceding three sentences. In the event Mr. Healds employment is terminated upon his death, his written designee, spouse or estate, as applicable, will be entitled to the
payments described in the first sentence of this paragraph. In the event Mr. Healds employment is terminated by us for disability, he will be entitled to the severance payments and benefits described in the first two sentences of this
paragraph.

For purposes of each agreement discussed above, cause means the discharge of the employee resulting from
(a) a conviction of a crime involving us; (b) an act or omission which has a material adverse effect on us; (c) fraud, misappropriation or embezzlement; or (d) the breach in any material respect of the material terms and
provisions of the agreement.

The severance benefits described above were extended to Messrs. John Casella, Coletta and Heald as an
inducement to their decisions to continue to remain employed by us and, in the case of Messrs. Johnson and Schmitt, as an inducement to accept employment with us. At the time each of such agreements was entered into, our Board considered a number of
factors, including severance arrangements offered by comparable companies, the importance of the respective employee to our ongoing success and the benefits of receiving a non-competition and non-solicitation covenant from the respective employee in
exchange for the agreed severance. The Compensation Committee considers the severance benefits to be separate from the compensation payable to employees for their ongoing services and accordingly does not consider the value of the severance package
when setting current compensation.

Equity Award Agreements

Under the terms of each named executive officers restricted stock unit agreements (other than Mr. Healds restricted stock unit
agreements for RSUs granted to him prior to 2016), if the named executive officers employment is terminated as a result of a change in control (as defined in the applicable restricted stock unit agreement), the officers death or
disability, or by the Company without cause, then all unvested RSUs will vest immediately.

Summary of Potential Payments Upon
Termination or Change of Control as of December 31, 2015

The following table quantifies the amounts that would be payable to
our named executive officers upon termination of their employment under the circumstances described above under Employment Agreements and a change of control of the Company. We calculated the amounts shown based upon each such named
executive officers employment agreement, if applicable, described above and upon the hypothetical assumption that we terminated each named executive officer effective December 31, 2015. Mr. Heald was not party to an employment
agreement in 2015 and entered into his employment agreement on March 1, 2016.

Director Compensation

We compensate our
directors who are not our employees or employees of our subsidiaries. Accordingly, Mr. John Casella, who serves as our Chief Executive Officer, and Mr. Douglas Casella, who serves as President of Casella Waste Management, Inc., our
wholly-owned subsidiary, do not receive any additional compensation for their service as directors.

The Compensation Committee
periodically reviews the compensation of our non-employee directors. We seek to attract exceptional talent to our Board and therefore, our policy is to compensate our directors competitively relative to comparable companies. Our Board believes that
it is appropriate for the chairs and members of the committees of our Board to receive additional compensation for their services in those positions.

For fiscal 2016, our non-employee directors will be entitled to receive the cash fees described above in consideration of their Board service.
In addition, Mr. Peters will receive a monthly payment of $3,125 in consideration of his monthly meetings with members of management on behalf of the Board.

Equity Compensation

Each new non-employee director receives a grant of shares of restricted Class A common stock on the date of such directors initial
election to our Board having a value on the date of grant of approximately $50,000, which vests in three equal annual installments beginning on the first anniversary of the date of grant. Each incumbent non-employee director, other than non-employee
directors who were initially elected to our Board at any time after the prior years annual meeting of stockholders, receives at each annual meeting of stockholders an additional grant of shares of restricted Class A common stock having a
value on the date of grant of approximately $50,000, which vests in three equal annual installments beginning on the first anniversary of the date of grant. Our Board adopted stock ownership guidelines for its non-employee directors that require
each non-employee director to attain a share ownership level of our Class A common stock equal to $100,000. Each non-employee director is required to attain such ownership levels by the third annual meeting of stockholders following the first
annual meeting of stockholders at which such non-employee director is elected to our Board.

The following table provides compensation
information for fiscal 2015 for each of our non-employee directors.

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth as of April 15, 2016 information regarding the beneficial ownership of our capital voting stock by (a) each
person or entity known by us to beneficially own more than 5% of any class of our common stock, (b) our directors and director nominees, (c) our named executive officers and (d) our directors and executive officers as a group.

We have determined beneficial ownership in accordance with the rules of the SEC. Shares of Class A common stock that an individual or entity
has a right to acquire within 60 days after April 15, 2016, including pursuant to options to purchase Class A common stock, Class B common stock convertible into Class A common stock and restricted stock unit awards subject to vesting, are included
in the number of shares of Class A common stock beneficially owned by the person or entity and are deemed outstanding for purposes of computing the percentage of beneficial ownership owned by the person or entity, but are not deemed outstanding for
purposes of computing the percentage beneficially owned by any other person or entity. Each share of Class B common stock is convertible at the discretion of the holder thereof into one share of Class A common stock. As of April 15, 2016, a total of
40,243,775 shares of Class A common stock were outstanding and a total of 988,200 shares of Class B common stock were outstanding. Except as otherwise indicated by footnote, we believe that the persons named in this table, based on information
provided by these persons, have sole voting and investment power with respect to the securities indicated. Unless otherwise indicated, the address of each beneficial owner listed in the table is care of Casella Waste Systems, Inc., 25 Greens Hill
Lane, Rutland, Vermont 05701.

|ITEM 13. | CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE.
|-------- | --------------------------------------------------------------------------

Certain Relationships and
Related Person Transactions

We have adopted a written policy and have established procedures regarding approval of transactions
between us and any employee, officer, director and other related persons, including those required to be reported under Item 404 of Regulation S-K. The policy requires that all related person transactions are reviewed by the Audit Committee and
approved by our Board.

With respect to bidding projects in excess of $500,000 in which a related person, including Casella Construction,
Inc. is a bidder, the Audit Committee has established a specific procedure. This procedure requires us to solicit a minimum of three qualified bids. The bid package is required to be sufficiently detailed to allow for direct comparisons of costs
between responsive bidders. Bids for work on which Casella Construction, Inc. or any other related person is bidding are required to be directed to a third party engineer for opening, compilation and tabulation. The bids are then evaluated by the
project team based on price, performance references, qualifications, experience, alternate bid items, proposed schedule, subcontractors qualifications/references, technical compliance and other bid information that is in the best interest of the
project. In the event that a construction contract is successfully bid by a related person, bids and recommendations are required to be submitted to our Chief Financial Officer and our President and Chief Operating Officer for submission to the
Audit Committee for review and to our Board for approval. With respect to sole source bids (i.e. those less than $500,000), the Audit Committee is required to be provided with documentation describing the reason for the work, a comparison of market
or historical prices to the bid price, and approval by our Chief Financial Officer or our President and Chief Operating Officer. Change orders relating to contracts with related parties are required to be forwarded to our Chief Financial Officer for
submission to the Audit Committee for review and to our Board for approval before the change order is approved; provided that change orders to existing contracts with related parties may be approved by our Chief Financial Officer and our President
and Chief Operating Officer (executive officers who are not affiliated with the related parties), as long as the total value of such change orders does not exceed 10% of the value of the contract, up to a maximum of $500,000, and subject to
ratification of the change order by our Board. Transactions not exceeding $75,000 individually or $300,000 in the aggregate in any fiscal year may, for administrative purposes, be approved by our President and Chief Operating Officer or our Chief
Financial Officer, subject to ratification and approval by the Audit Committee and our Board.

The loan and security agreement for our
senior secured asset-based revolving credit facility provides that, subject to certain exceptions, we may not enter into any transaction with any affiliate of ours, whether or not in the ordinary course of business, unless our Board determines in
good faith that such transaction is on fair and reasonable terms substantially as favorable as would be obtainable by us at the time in a comparable arms length transaction.

With respect to related person transactions involving aggregate consideration in excess of $10.0 million, or in excess of $5.0 million if such
transaction is not approved by a majority of disinterested directors, subject to certain exceptions, we are required by the terms of our debt instruments to obtain an opinion as to the fairness of such transactions from a financial point of view
issued by an accounting, appraisal or investment banking firm of national standing.

Our related person transaction policy also provides
that transactions involving compensation of executive officers shall be reviewed and approved by the Compensation Committee in the manner specified in its charter.

We engage Casella Construction, Inc., a company owned by John W. Casella, our Chief Executive Officer and the Chairman of our Board, and
Douglas R. Casella, the Vice Chairman of our Board, to provide construction services for us, including construction, closure and capping activities at our landfills. Total purchased services from Casella Construction, Inc. charged to operations or
capitalized to landfills for fiscal 2015 was $1,340,629, of which $27,625 was outstanding and included in either accounts payable or other current liabilities at December 31, 2015. In addition, we have approved ongoing contracts with Casella
Construction, Inc., which we expect will result in additional payments by us to Casella Construction, Inc. In 2015, Casella Construction, Inc. contributed $350,000 in cash and $390,000 in non-compensable services for work performed at our
Southbridge landfill to assist in the remediation of the site as a part of our settlement with the Massachusetts Office of the Attorney General.

We are also party to two real estate leases with Casella Associates, LLP, a Vermont limited liability company owned by Messrs. John
Casella and Douglas Casella. These leases relate to our corporate headquarters in Rutland, Vermont and our Montpelier, Vermont facility, and provide for aggregate monthly payments by us of $27,375, subject to an annual escalation provision based on
increases in the consumer price index, through their expiration in April 2018. These leases include a five year lessee renewal option with terms consistent with the current leases.

From 1977 to 1992, we operated an unlined landfill located in Whitehall, New York owned by Bola, Inc., a corporation owned by Messrs. John
Casella and Douglas Casella, which operated as a single-purpose real estate holding company. We paid the cost of closing this landfill in 1992, and have agreed to pay all post-closure obligations. In fiscal 2015, we paid an aggregate of $9,230
pursuant to this arrangement. As of December 31, 2015, we had accrued $74,615 for costs related to those post-closure obligations.

Board Determination of
Independence

Our Second Amended and Restated Certificate of Incorporation and our By-Laws provide for the classification of our
Board into three classes, each having as nearly an equal number of directors as possible. The terms of service of the three classes are staggered so that the term of one class expires each year. At each annual meeting of stockholders, directors
are elected for a full term of three years to continue or succeed those directors whose terms are expiring.

Our Board currently consists
of nine directors. Class I consists of James F. Callahan, Jr., Douglas R. Casella and Michael K. Burke, each with a term ending at the 2016 Annual Meeting of Stockholders. Class II consists of Gregory B. Peters, Joseph G. Doody and Emily
Nagle Green, each with a term ending at the 2017 Annual Meeting of Stockholders. Class III consists of John W. Casella, William P. Hulligan and James E. OConnor, each with a term ending at the 2018 Annual Meeting of Stockholders.

Under the applicable rules of the NASDAQ Stock Market, a director will only qualify as an independent director if, in the opinion
of our Board, that person does not have a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Our Board determined that none of Ms. Nagle Green or Messrs. Burke,
Callahan, Doody, Hulligan, OConnor and Peters has a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is an independent
director as defined under Rule 5605(a)(2) of the NASDAQ Marketplace Rules. The Board also determined that Mr. Chapple, a former director, was an independent director prior to his retirement from our Board on July 7, 2015 and that
Mr. McManus, a former director, was an independent director prior to his retirement from our Board on August 31, 2015.

Our
Board has established three standing committeesAudit, Compensation and Nominations and Governanceeach of which operates under a charter that was approved by our Board.

Our Board determined that all of the members of each of its three committees are independent as
defined under the rules of NASDAQ, including, in the case of all members of the Audit Committee, the independence requirements under Rule 10A-3 under the Exchange Act, and, in the case of all members of the Compensation Committee, the
independence requirements under Rule 10C-1 under the Exchange Act. Our current non-employee directors serve on the committees of our Board as follows:
