Item 4.                                                         Purpose of Transaction
 
The Reporting Persons acquired the Shares covered by this Statement because, in their opinion, such Shares are undervalued, and the current share price does not adequately reflect the potential for significant earnings and cash flow growth.
 
The Reporting Persons believe improvements in a number of areas will further enhance the Company’s equity valuation. Since their initial investment in February 2014, the Reporting Persons have maintained a dialogue with the Company’s management and have presented their views and concerns regarding (i) undervaluation of high return businesses, (ii) portfolio strategic review, (iii) operational improvements, and (iv) capital allocation. The Reporting Persons believe the Company has  and will continue to take actions to improve its performance in these areas.
 
Undervaluation of High Return Businesses
 
The Reporting Persons believe the Company’s dominant position in hazardous waste collection, transportation, and disposal is severely underappreciated. The Company’s legacy Technical Services and Industrial & Field Services businesses, which represent 66% of total company EBITDA, consistently earn a high return on invested capital and benefit from material barriers to entry.  These characteristics warrant a premium valuation relative to the Company’s current trading multiple. The Reporting Persons support the Company’s long-term plan to invest in capacity expansion in these businesses.
 
Portfolio Strategic Review
 
During its fourth quarter earnings call on February 26, 2014, the Company announced a broad strategic review of its operating structure with a focus on driving organic growth and improving its return on invested capital. The Reporting Persons support such actions which may include divestitures or a tax free spin-off of assets that do not earn their cost of capital, do not directly feed waste streams to the Company’s high return disposal assets or lie outside of the Company’s core competency in waste disposal.  The Reporting Persons believe the Company will benefit from a higher Enterprise Value to EBITDA multiple as it refocuses its business mix and improves its return on invested capital.
 
Operational Improvements
 
The Reporting Persons believe that improvements in profit margins and asset utilization will be increasingly important to creating superior equity value. Recent meetings between representatives of the Reporting Persons and the Company’s executive management have increased the Reporting Persons’ confidence that the management team is intently focused on achieving its stated long-term EBITDA margin target of 20%, as announced during the Company’s investor presentation on September 19, 2013. The Reporting Persons are confident that management is focused on SG&A expense reduction, disposal network optimization, asset utilization improvement, profitability improvement of its Oil Re-refining business, and the successful implementation of its recently announced $75 million cost savings initiative.
 
Capital Allocation Discipline
 
The Reporting Persons believe the Company will have substantially completed the investments necessary for its strategic positioning by 2015. Therefore, a larger portion of excess cash flows in future periods will be available for distribution to shareholders through dividends and share repurchases. The Reporting Persons believe that the Company’s expected annual future cash flows and potential divestiture proceeds make capital allocation an increasingly important component of equity value creation. The Reporting Persons have been communicating with the Company to help ensure that the Company has capital allocation processes and disciplines in place to ensure that future free cash flows are allocated to the highest and best return alternatives. Based on the Company’s current valuation, the Reporting Persons believe share repurchases represent a low-risk, high-return hurdle against which all alternative uses of capital, particularly acquisitions, must be benchmarked.
 
The Reporting Persons intend to closely monitor the Company’s progress in each of these areas and may modify their plans accordingly.
 
The Reporting Persons may exercise any and all of their respective rights as shareholders of the Company in a manner consistent with their equity interests. The Reporting Persons and their representatives and advisers intend to continue to discuss the Company and its performance with members of the Company’s board and management. In addition, the Reporting Persons may communicate with other shareholders, industry participants, and other interested parties about issues concerning the Company. Although the Reporting Persons do not have any current plans, other than the monitoring and communication program outlined above, the Reporting Persons may in the future decide to seek representation on the Company’s board of directors. Among other factors, the Reporting Persons will consider the Board’s oversight of the execution of operational improvements and capital allocation strategies for maximizing shareholder value as major factors in its decision of whether or not to nominate independent director candidates.
 
The Reporting Persons may from time to time (i) acquire additional Shares (subject to availability at prices deemed favorable) in the open market, in privately negotiated transactions or otherwise, or (ii) dispose of Shares at prices deemed favorable in the open market, in privately negotiated transactions or otherwise. The Reporting Persons may formulate plans or proposals for, and may from time to time explore, or make proposals relating to, transactions or actions which relate to or would result in any of the matters specified in clauses (a) through (j) of Item 4 of Schedule 13D.

Item 5.   Interest in Securities of the Issuer
(a)           As of the date of this Statement, the Reporting Persons beneficially owned in the aggregate 5,516,622 Shares, constituting 9.08% of the outstanding Shares.  The percentage of Shares owned is based upon 60,723,422 Shares outstanding on February 26, 2014, as set forth in the Issuer’s Form 10-K for the year ended December 31, 2013.  The Reporting Persons may be deemed to have direct beneficial ownership of the Shares as follows:
NAME	 	NUMBER OF SHARES	 	% OF OUTSTANDING SHARES	 	VOTING AND DISPOSITIVE POWER	 	
RILLC	 	1,719,308	 	2.83	%	Sole	 	
MC I	 	1,081,541	 	1.78	%	Sole	 	
MC II	 	1,478,149	 	2.43	%	Sole	 	
RFP	 	17,087	 	0.03	%	Sole	 	
RCP	 	168,260	 	0.28	%	Sole	 	
RI IX	 	218,165	 	0.36	%	Sole	 	
RI XV	 	178,914	 	0.29	%	Sole

RI XXIII	 	225,349	 	0.37	%	Sole	 	
RI XXIV	 	27,505	 	0.05	%	Sole	 	
RHF 1	 	149,702	 	0.25	%	Sole	 	
 
RILLC, individually and in its capacity as an investment adviser, may be deemed to possess direct beneficial ownership of the 1,719,308 Shares that are owned by it and the Managed Accounts.  Additionally, RILLC, as the sole general partner, or sole managing member of the general partner, of each of the Relational LPs may be deemed to beneficially own (as that term is defined in Rule 13d-3 under the Securities Exchange Act of 1934, as amended) the 3,797,314 Shares beneficially owned by the Relational LPs because the limited partnership agreements of the Relational LPs specify that RILLC has sole investment discretion and voting authority with respect to those Shares.
 
Each of Messrs. Whitworth and Batchelder, as Principals of RILLC, may be deemed to share indirect beneficial ownership of the Shares which RILLC may beneficially own.  Each of Messrs. Whitworth and Batchelder disclaims beneficial ownership of such Shares for all other purposes.
 
To the best of the knowledge of each of the Reporting Persons, other than as set forth above, none of the persons named in Item 2 is the beneficial owner of any Shares.
 
(b)           See item (a) above.
 
(c)           Except as set forth in Exhibit A to this Statement, none of the Reporting Persons has effected any transactions in the Shares during the past sixty days.
 
(d)           No other person is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares covered by this Statement, except that dividends from, and proceeds from the sale of, the Shares held by accounts managed by RILLC may be delivered to such accounts.
 
(e)           Not applicable.
 
Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
 
Except for the joint filing agreement between and among the Reporting Persons attached hereto as Exhibit B, and except for the investment discretion and voting authority described in Item 2 of this Statement and in the respective partnership agreements and investment management agreements of the Relational LPs and Managed Accounts which each contain provisions whereby RILLC may, after certain adjustments, receive a percentage of realized or unrealized profits, if any, derived from that partnership’s or managed account’s investments, to the best of the knowledge of the Reporting Persons, there are no contracts, arrangements, understandings or relationships (legal or otherwise) among the Reporting Persons or between the Reporting Persons and any other person with respect to any securities of the Issuer, including but not limited to transfer or voting of any of the securities, finder’s fees, joint ventures, loan or option arrangements, puts or calls, guarantees of profits, division of profits or loss, or the giving or withholding of proxies.
