As chemical use in every industry has become an increasing public concern, many governing bodies have implemented measures to enforce regulations and provide public access to relevant information. This is also true in the oil and natural gas industry, which is primarily regulated at the state level. Prior to 2011, there was no comprehensive database of chemicals used in the hydraulic fracturing of wells. This was the catalyst for the creation of FracFocus.org, a national database providing public access to information regarding hydraulic fracturing chemicals.
To date, 30 out of 34 oil and gas producing states have rules that require information about chemicals used in fracturing wells to be made public. Of these, 27 either require or allow the use of FracFocus as a means of regulatory reporting.
