Alternatives for this final rule have not yet been determined. The EPA proposed both methane and VOC standards for several emission sources not currently covered by the NSPS (i.e., hydraulically fractured oil well completions, fugitive emissions from well sites and compressor stations, and pneumatic pumps). In addition, the EPA proposed methane standards for certain emission sources that are currently regulated for VOC (i.e., hydraulically fractured gas well completions, equipment leaks at natural gas processing plants). The proposed amendments would establish methane standards for certain equipment across the source category and extend the current VOC standards to the remaining unregulated equipment. Lastly, amendments proposed to the current NSPS that improve implementation of several aspects of the current standards. Except for the implementation improvements and the setting of standards for methane, these amendments do not change the requirements for operations already covered by the current standards. The EPA has incorporated flexibility to the extent possible into the proposed rule affected sources can achieve emissions reductions in a cost-effective way. In additional to proposing alternatives options where possible, the EPA solicited comments on alternative approaches. We believe that affected sources already complying with more stringent State requirements may also be in compliance with this rule. Furthermore, the EPA is mindful that some facilities that will be subject to the proposed EPA standards will also be subject to current or future requirements of the Department of Interior's Bureau of Land Management (BLM) rules covering production of natural gas on Federal lands. The EPA and BLM have maintained an ongoing dialogue during development of this action to identify opportunities for alignment and ways to minimize potential conflicting requirements and will continue to coordinate through the agencies' respective proposals and final rulemakings.
