Several new Marcellus Shale-related bills have been introduced in the Pennsylvania Senate and House of Representatives since the start of 2011. House Bill 833, first introduced on March 1, 2011 and known as the Natural Gas Severance Tax Act, proposes to impose a tax on natural gas extraction of 30 cents per 1,000 cubic feet. The bill also provides an exemption for wells with low production rates (less than 60,000 cubic feet/day) known as "stripper wells" to incentivize operators' continued use of those wells in lieu of drilling new wells. House Bill 33, which was introduced on February 9, 2011 and shares many of the same legislative sponsors as H.B. 833, proposes a tax of 5% on all gas extracted plus an additional 4.6 cents per 1,000 cubic feet. This tax rate is the same as that proposed under Senate Bill 352, which was introduced on February 1, 2011. House Bill 234, introduced on January 26, 2011, would provide for further reporting requirements for operators producing gas from "unconventional shale formations" (including the Marcellus, Burket, Utica, Mandata, and Rhinestreet Shale formations, etc.). House Bill 232, also introduced on January 26, 2011, provides for additional restrictions on well locations and permits, as well as wastewater disposal requirements and a cumulative impacts study.

In addition to the introduction of new bills, several new regulations addressing well casing requirements, which the Pennsylvania General Assembly approved in the fall of 2010, went into effect in early February upon publication in the Pennsylvania Bulletin. We previewed these requirements in November 2010.
