26 | ENVIRONMENTAL, HEALTH & SAFETY INVESTING IN OUR WORLD AND OUR PEOPLE  » As we explore for and produce clean, affordable, abundant, American  natural gas, we provide an important solution to our nation’s energy  challenges and its quest for energy independence. With at least a 200- year supply of natural gas located right here in the U.S., this versatile  fuel can be used to not only heat homes, create electricity and meet  America’s transportation needs, but also to fuel the country’s future  by creating jobs and stimulating local and national economies through investment and taxes.  Environmentally Friendly Operations At Chesapeake, we realize that the way a great product is produced is  as important as the product itself. For example, we have helped pioneer  the use of multiwell padsites to drill up to 16 wells from a single loca- tion, greatly reducing our land and road use and overall environmental  footprint. We use the latest horizontal and directional drilling technology  to place wells at a safe distance from homes, schools and businesses. In  addition, we build and maintain access roads and work to eliminate soil  erosion near our sites, as well as restore local vegetation.  We implement advanced, modern protective measures known as Best  Management Practices (BMPs) to help ensure energy development is con- ducted in an environmentally responsible manner. Procedures are imple- mented throughout our operations to protect freshwater aquifers and  reduce environmental impacts. BMPs protect wildlife, air quality, water and  landscapes as we work to develop vitally needed domestic energy sources.  Implemented throughout the entire life cycle of a well, BMPs can be  as simple as strategically placing a berm, or land barrier, on locations  to control surface water runoff. Others involve cutting-edge operational  technologies such as utilizing the most advanced techniques offered in  drilling fluids, well casing and cement design. Regardless of complex- ity, all BMPs are based on the idea that the environmental footprint of  energy development should be as small and temporary as possible.  These practices are continually evolving and further improving as  Chesapeake and the industry develop new innovative techniques and  approaches to business.  In addition to our BMPs, Chesapeake has also initiated several  innovative internal programs focused on water recycling and greener  hydraulic fracturing processes.  Aqua Renew ® Created to meet the challenge of reducing our water usage, Chesapeake’s  Aqua Renew ®  program uses state-of-the-art technology to recycle pro- duced water. Since the  company’s  preliminary  reclamation project in  2006, our focus on water reuse and conservation has become a company- wide endeavor, stretching from the Barnett Shale of North Texas to the  Marcellus Shale of northern Pennsylvania.  The  Aqua Renew program has yet to find a limit to how much  recycled water could be used without compromising well production.  In fact, our Marcellus Shale operations are treating and recycling virtu- ally 100% of produced water (more than 10 million gallons per month)  for reuse in our hydraulic fracturing operations. Properly conducted  modern fracking is a highly engineered, controlled, sophisticated and  safe procedure. With such large volumes of recycled water, the company is see- ing more than just environmental advantages. We estimate that this  Green operations — Chesapeake’s Best Management Practices ensure our  operations are as environmentally friendly as possible, while protecting  our employees, neighbors and the areas where we operate.
