DEQ staff monitor the environmental impacts of well drilling operations, brine disposal wells, oil and gas production facilities, and gas storage wells. Permits have been issued for over 56,000 oil and gas wells in the state. Their activities include permit application reviews, field reviews, compliance inspections, enforcement, and spill response. The Division has implemented a computerized system that allows the electronic entry and tracking of oil and gas well applications, field inspection activities, compliance cases, and production information. This system also electronically issues oil and gas permits and well transfers. Formal hearings are held before the Supervisor of Wells to receive evidence pertaining to the administration of Part 615, of the Natural Resources and Environmental Protection Act, 1994 PA 451, as amended (NREPA), and promulgated rules.
