The graphs on the left show the rate of growth compared to the earliest year for which we have data -- in most cases 2003. The gray lines represent a theoretical constant annual rate of change. The bar charts on the right show the actual values for each year we have data. For example, in 2011, Ohio had 460 new wells drilled.

32 enforcement staff for 64,481 wells in 2011
2,455 class 2 underground injection wells in 2010, according to the EPA | More »

Notes: Data are for the calendar year. Ohio is in the process of expanding its enforcement staff. By early 2013, they expect to have filled up to 90 field inspection positions. The oil and gas division no longer receives general revenue funding and is currently financed by revenues generated from severance tax on oil and gas and other fees. For 2009 through 2011, total well counts come from the Summary of Ohio Oil and Gas Activities from the Division of Mineral Resources Management.
