The goal of their rewrite is to incorporate all their criticisms of the report, however insubstantial, that would undermine its conclusions.
Nine members of the Advisory Council voted for the motion. The Council chair did not announce the number of votes against the motion or any who abstained. The Council has 17 members.

Dr. William Burgos, lead author of a new Penn State University study of road dumping conventional oil and gas wastewater released in May, answered questions about the study at the meeting for more than two hours.
The study found the wastewater running off the roadways after spreading contains concentrations of barium, strontium, lithium, iron, manganese that exceed human-health based criteria and levels of radioactive radium that exceed industrial discharge standards. Read more here.
“The story for all of these brines is whatever you put on the road, it's washing off into the adjoining ditch,” said Dr. Burgos. “And then in the case of oil and gas produced waters, especially that one sort of regional average one with the highest radium activity had the highest concentrations of radium in the runoff, both in the first flush and mobilized with solids.”
“With respect to efficacy, as we showed through the dust generation experiments, they're little to no more effective than simply rainwater or going out and watering your roads, if you want to do that,” Dr. Burgos added. Read more here.
Representatives of the conventional drilling industry primarily took issue with the samples of drilling wastewater tested during the study saying it was not representative of the waste they produce.
“The study screwed us, because it used water that doesn’t represent our industry,” said one member.
They said the amount of one pollutant-- Total Dissolved Solids-- was too low-- 84,000 mg/L versus what they say is a more representative sample would have had at least 115,000 mg/l.
The EPA/DEP Total Dissolved Solid standard is 500 mg/L
A second pollutant-- radioactive radium-- was too high, the industry representatives said. The sample used by Penn State in their study contained 2,500 pCi/L when the industry said between 1,000 and 1,600 pCi/L was more representative.
The Nuclear Regulatory Commission standard for industrial wastewater is 60 pCi/L. The combined radium EPA/DEP standard in drinking water is 5 pCi/L.
The Penn State study shows the conventional drilling wastewater tested exceeds, and in many instances far exceeds, the environmental or health standards for 25 of the 31 parameters tested for in the study
Dr. Burgos said the drilling wastewater they tested in the study was intended to be representative of wastewater produced in Northwest Pennsylvania where much of the conventional oil and gas drilling happens.
“We agree there is a geochemical mismatch between radium and TDS [Total Dissolved Solids],” said Dr. Burgos. “But, what I would argue, what I’m gonna say is the salts are all washing off [the road], the radium is in the salts.
“If you had 1,600 pCi/L instead of 2,500 pCi/L you are still getting over that 60 pCi/L [Nuclear Regulatory Commission standard] that washes off the road.
“I would be concerned with any of these produced waters with a thousand or more pCi/L for sure. My guess is they are going to generate these kind of numbers,” Dr. Burgos added.
Dr. Burgos also repeated a recommendation in the study saying DEP should look at regulating commercial products using calcium chlorides-- salts-- to treat roads to prevent ice formation because their concentrations of pollutants is often higher than even the conventional drilling wastewater.
Kurt Klapkowski, Acting DEP Deputy Secretary for Oil and Gas Management, told the group--
“The report is what it is, based on submissions to the department and released on, I think it was, May 26th. This is a document that reflects a moment in time. We’re three months after that day.
“We can certainly say whatever we want to say about the report when we're talking about today and we're having a discussion about it but the report is what it is. This was what was given to the department and what was accepted on May 26th, 2022.”
