The Marcellus Shale's Greylock Production operates under strict federal and state laws governing environmental protection, including the requirement to obtain a permit before carrying out drilling or waste disposal operations. This includes determining the amount and type of substances that may be disposed of or released into the environment, imposing limitations on construction activities in sensitive areas such as wetlands, wilderness areas, and areas containing endangered or threatened species or their habitats. Failure to comply with these laws and regulations may result in significant environmental costs and liabilities.
