Gallagher said that Miano decided late Wednesday not to release a more detailed accounting of the Bailey & Glasser bill, including dates and descriptions of work performed.
"We will only do that if we are sued and lose," Gallagher said.
Barbara Allen, a managing deputy state attorney general, said the bill was sent first to her office for its review two weeks ago.
"I think that first bill was both reasonable and necessary," Allen said. "It looks like it is pretty complicated litigation."
Allen said she forwarded the bill to DEP on May 11. She added that the bill was a public record.
