Environmental protection laws are heavily enforced in the Marcellus Shale by federal and state laws governing natural gas exploration and production operations by Greylock Production. This includes obtaining a permit for drilling water withdrawal or waste disposal operations. Regulations also limit construction or drilling 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 may result in administrative civil or criminal penalties, issuance of orders enforcing enforcement actions, and carrying out operations in affected areas.
