Charity Rehab pays 12 top staff members more than €100,000, with 77 staff earning more than €65,000.
Plus, CEO Angela Kerins is paid €240,000 while another 11 executives at the charity earn over €100,000.
The charity released further details of the salaries paid to senior staff in response to a list of questions from the PAC sent to the charity on March 4.
Environment Minister Phil Hogan criticised PAC chairman John McGuinness last night, accusing him of "behaving politically" in his role.
According to the rules of PAC its chairman should be above party politics at all times while acting in his role examining the use of taxpayers' money.
Mr Hogan said Mr McGuinness had personalised issues by focusing on former Fine Gael director of elections, Frank Flannery.
On Monday Mr Flannery resigned as a director at the charity and as a Fine Gael consultant, following calls for him to appear before PAC to answer questions about pay and pensions at Rehab.
"Mr McGuinness, the chairman, has said today that it wasn't about Frank Flannery at all – that it was about Rehab.
"But he wasn't saying that on the local radio stations around the country yesterday. So, I have to come to the conclusion on that basis that Mr McGuinness is behaving politically," said Mr Hogan.
Mr McGuinness and other PAC colleagues have rejected the accusations and said that Mr Flannery's failure to answer questions at the committee had caused the controversy.
When asked about the criticisms of Mr Flannery by Fine Gael Wicklow TD, Simon Harris, Minister Hogan said he was not aware of those.
"I'm not a member of PAC. I didn't read about them – I read the comments made by John McGuinness," he said.
The minister paid a glowing tribute to the work of Mr Flannery for Rehab and Fine Gael.
He said Mr Flannery worked with Rehab since 1973 and was CEO for 25 years building it into a world class organisation.
"I think that an awful lot of families in this country are very grateful to him," the minister said.
