11 Fall 2014 the Professional Engineer n Require a siting study at the frst and preliminary phase of the well pad siting process. n Develop a siting approval process that is similar to those used for other energy facilities including National Environmental Protection Agency studies and environ- mental impact studies. 3. Long-term contaminated water treatment issues. One of the long-term issues associated with fracking for shale gas/natural gas is the tremen- dous volume of afected water that is created over the lifetime of energy resource development. As a region attempts to store and treat the afected water, it is very common for the wastewater treatment capacity to be overwhelmed. (See the previous page for an illustration of the large volume of excess contaminated water that must be addressed over the 20-to-30-year life of a shale gas extraction area.) Potential solutions: Te NCMEC has developed a water use plan that minimizes the use of groundwa- ter for the fracking and well development process. In addition to these protective measures, the following are suggested: n Require as part of the siting process that the well owner and installation company identify wastewater treatment facilities in the area within a 100-mile radius of the site. n Keep an inventory of the wastewater treatment capacity that is available and used in the area near well pads and natural gas extraction areas. Tis approach is very similar to the siting requirements for municipal solid waste landflls in North Carolina, where the volume of leachate produced and available treatment capacity are identifed prior to permit approval.
