The Pennsylvania Department of Environmental Protection (DEP) has launched a website to track oil and gas operations in the state, including those in the Marcellus Shale. The website includes reports on permitting and drilling figures, well inventories organized by county and operator, and violations. The DEP previously listed permitting and drilling information by month and production information twice each year, but the new website allows the public to view individual inspection reports. Additionally, the Pennsylvania Public Utility Commission (PUC) recently created a website to help pipeline operators comply with new oversight requirements. Gov. Tom Corbett signed Act 127 in late December, making the PUC the “state agent” for the U.S. Pipeline and Hazardous Material Safety Administration in Pennsylvania and giving the PUC oversight over most nonutility natural gas pipelines. Among other things, the act requires the PUC to create a registry of all nonutility gas and hazardous liquids pipelines in the state, and the website includes forms to help operators comply. The act takes effect on Feb. 20.

Line 4 was shut in and deliveries from REX at their Glouster, PA, interconnect were halted following a November rupture near MLV 205-4 in Morgan County, OH.
