Pittsburgh, PA — September 4, 2012 — Heckmann Corporation (NYSE: HEK) (the “Company”) today announced that it has entered into a definitive agreement (“the Agreement”) with Mark Johnsrud, founder and owner of Badlands Energy, LLC, a North Dakota limited liability company doing business as Power Fuels (“Power Fuels”), to merge with Power Fuels, a privately held North Dakota-based environmental services provider focused on the transportation, treatment, recycling, and disposal of fluids at Power Fuels’ sites. Power Fuels is the largest environmental services company in the Bakken Shale basin, a premier unconventional oil shale. The business combination accelerates Heckmann’s strategy of providing a one-stop-shop for comprehensive environmental solutions. The merger is expected to be highly accretive to Heckmann’s earnings per share and is expected to close in the fourth quarter of 2012. The Agreement, and completion of the merger, is subject to customary regulatory approvals, such as filings under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, and customary closing conditions including the approval of Heckmann’s stockholders, which is required under NYSE listing standards to issue shares in connection with this transaction.

Through June 30, 2012, Power Fuels generated trailing 12-month revenues of approximately $363.5 million and trailing 12-month adjusted EBITDA of approximately $154.7 million⁴. Under terms of the Agreement, Heckmann plans to pay $125.0 million in cash and 95.0 million shares of the Company’s common stock⁵, subject to, among other things, a two-year lockup agreement and a two-year standstill agreement. Heckmann will also assume/refinance approximately $150 million in Power Fuels’ debt. The Company is in discussions with its current lending group to expand the size of its credit facility to accommodate the transaction.

The transaction significantly expands Heckmann’s total environmental solutions operations. The business combination is expected to double Heckmann’s annual revenue, extend its geographic reach and broaden Heckmann’s customer base. The combined Company will continue to expand its environmental service offering by leveraging the respective strengths of each organization, including the recently acquired Thermo Fluids Inc. business with its environmental recycling expertise. The combination is expected to create value for the stockholders through:

On a pro-forma basis, after giving effect to the cash and refinanced debt of the transaction, the combined Company’s leverage ratio would have been reduced to approximately 2.6 times trailing 12-month adjusted EBITDA as of June 30, 2012.

“Just three years ago, in the Summer of 2009, we set out to build the largest environmental services company in the United States, operating in a completely new market segment. We are well down that path, and one billion dollars in revenue is within our reach,” said Mr. Richard J. Heckmann, Chairman and Chief Executive Officer of Heckmann Corporation. “Producers in the U.S. shale basins are extremely focused on environmental solutions and looking for what we offer – a large nationwide company with dedicated services to handle their environmental needs. Our multi-basin presence allows us to migrate and expand with our customers as they further develop their shale assets. As their results show, the Power Fuels team is comprised of top-tier operators, and they will significantly complement our operating team. Together, we have constructed a nationwide footprint with approximately 3,000 employees and an expanding environmental services offering. We are the only company that we know of offering all of the above. In addition, our proprietary paperless tracking, billing and regulatory reporting capabilities, along with our access to the latest treatment technologies, sets us apart from others entering this new segment.”

Mr. Heckmann continued, “In addition, our earlier acquisition of Thermo Fluids and its recycling expertise now becomes a critical element in leveraging our comprehensive environmental solutions services. We will not only manage all facets of water transport, re-use, treatment and disposal, but also provide recycling services including closed-loop solid waste management, oil reclamation, antifreeze collection and re-manufacturing, oil filter collection and recycling, and tank bottom and oily waste treatment for a diverse

customer base that seeks to consolidate their supplier base. Our executives and managers are some of the most experienced in the environmental business and understand the issues around the recycling, treatment, movement and disposal of fluids connected with domestic energy. We believe we have built a truly unique and expansive full-service environmental services business and have now added significant scale and operating experience.”

Governance and Management

Upon closing of the transaction, Mr. Heckmann will become Executive Chairman of the Board with full time responsibilities including leading the Company’s Board and overall corporate strategy. Mr. Johnsrud will join the Heckmann Board of Directors as Vice Chairman and become Chief Executive Officer of the Company. Mr. Johnsrud has been the CEO of Power Fuels since he acquired the business in 2005 and is a former senior executive with several financial services firms, most recently as a Managing Director and Senior Vice President at Bank of America. He holds an M.S. degree in economics from Texas A&M University. In addition, Jay Parkinson will join the business in the near term as Executive Vice President and Chief Financial Officer. Mr. Parkinson joins the Company from Jefferies & Company, Inc., where he was a Managing Director in the firm’s Energy Investment Banking group. Chuck Gordon will continue to direct the water business and serve as President of the newly created Fluids Management Division, which will include Power Fuels. James Devlin, who joined the Company with the Thermo Fluids acquisition last Spring, will be President of the newly created Recycling Division. Chris Chisholm will continue to serve the Company as Executive Vice President and CFO of the Fluids Management Division. Damian Georgino will continue in his role with the Company as Executive Vice President and Chief Legal Officer.

“I am extremely excited about this transaction. The merger will form a leading environmental services business focused on providing a comprehensive, single source for environmental solutions,” said Mr. Johnsrud. “The unconventional shale plays are a game-changer for the U.S. domestic energy equation, and the key issue for producers is ensuring top-tier environmental management of their operations. The combined company is ideally suited to provide professional and comprehensive environmental solutions to our customers, and for some time they have asked us to consider expanding our services. As we merge our organizations, we are building a company that can provide leading service and technology for our combined customer base. The expanding focus on domestic energy development will also give our workforce an exciting platform for professional growth.”

Mr. Johnsrud continued, “I am also very excited about the opportunity to work with Dick as we build this Company. Dick has decades of experience, having built three separate billion dollar plus companies listed on the NYSE, and his experience will be invaluable working on overall corporate strategy and direction of the business.”

Power Fuels operates a fleet of nearly 500 water trucks and 19 disposal wells in the Bakken Shale area, as well as a large water-related rental fleet of equipment. The merger of the Power Fuels and Heckmann operations will bring the Company’s fleet to approximately 1,300 heavy-duty trucks, 3,800 frac tanks, 2,000 other fluid handling and solid-waste tanks and other environmental services equipment, 200 rail cars and more than 45 disposal wells, with additional wells in the permitting process. Upon completion of the acquisition, Heckmann will have over 300 miles of permanent and temporary piping and operate 70 locations across 26 states with 3,000 employees and more than 20,000 customers.
