Correction: Gas Drilling-Chemicals story

In a Dec. 13 story about Texas' adoption of rules requiring gas and oil drillers to disclose the chemicals they use in hydraulic fracturing operations, The Associated Press reported erroneously that companies will not be required to disclose the concentrations of the chemicals they use in their mixes. The companies will be required to disclose the concentrations of chemicals regulated by the U.S. Occupational Safety and Health Administration, but will not be required to report the concentrations of unregulated chemicals.
