Experts in RFF's Center for Energy Economics and Policy analyzed 25 regulatory elements related to shale gas development in 31 states that have actual or potential development activity, offering the most comprehensive review of state shale gas regulations to date.
A key finding of the report is the regulatory heterogeneity among the states. States regulate different elements with different types of regulatory tools and varying levels of stringency. This heterogeneity does not necessarily mean some states lag while others lead; local conditions may justify very different rules. However, preliminary analysis in the report has revealed limited evidence of the sources of heterogeneity.
