Under the rules, companies are allowed to claim exemptions from public disclosure if they deem the chemical formulas trade secrets. But Wrotenbery said regulators would have access to that information.
“The agency can get that information in emergency response situations or in the investigation of complaints,” Wrotenbery said.
Mike Terry, president of the Oklahoma Independent Petroleum Association, said the energy industry is in favor of disclosing the chemicals in hydraulic fracturing. But companies differed in where the chemicals should be disclosed. The association prefers the Corporation Commission, he said.
“The majority of our members are familiar with the Corporation Commission and feel they have more say there in the rule-making process and through the election of the commissioners,” Terry said.
In public comments about the proposed rule, the Sierra Club said
“We think it's a great step forward and a great first step,” said David Ocamb, director of the Oklahoma chapter of the Sierra Club. “We look forward to expanding on the rule later.”
If approved by the Legislature, the rules would go into effect Jan. 1, 2013, for companies using hydraulic fracturing on horizontal wells. The rules would start in 2014 for companies fracturing other types of wells.
Wrotenbery said the two-step implementation will allow for additional time for smaller producers, who don't do much horizontal drilling, to become familiar with the reporting requirements.
We think it's a great step forward and a great first step. We look forward to expanding on the rule later.”
