Victoria's Country Fire Authority (CFA) has been accused of refusing to hand over vital information to a parliamentary inquiry into chemical contamination at the Fiskville training college.

The committee's chairwoman Bronwyn Halfpenny said there had been "extensive withholding of information" that was crucial to understanding what happened at Fiskville, in a special report tabled in the Parliament.

She said it had received the minutes of just 100 out of 739 CFA board meetings between 1971 and 2014, despite requesting the documents by summons.

"Decision-makers within the CFA have done a disservice to the CFA legacy and CFA firefighters twice over," Ms Halfpenny said.

"First the tragedy of Fiskville itself and now the refusal to provide vital information to this inquiry."

The CFA refused to provide agendas, minutes and documents tabled at meetings, including minutes from 22 meetings in 1987 when requests were made for information about chemicals used at the base, the committee said.

It also accused the CFA of claiming that documents no longer existed, extensive redactions and producing documents in a slow, ad hoc fashion.

"These documents and information being withheld go to the very heart of the terms of reference we are required by Parliament to investigate," the report said.

The committee is examining claims dozens of firefighters who worked or trained at Fiskville suffered cancers linked to dangerous firefighting chemicals over several decades.

The CFA's chief executive Lucinda Nolan said the authority had provided all documents requested by the inquiry to the Victorian Government Solicitors Office (VGSO).

"The VGSO has determined many of the documents may be subject to a claim of 'executive privilege' by the Government while others were not relevant to the terms of reference," she said.

"It is a matter for the Government to determine whether those documents can be provided to the inquiry."

Emergency Services Minister Jane Garrett said she would discuss the committee's concerns about the pace at which CFA documents were being produced with the VGSO.

"There has been a delay in some of these documents being released and I will be making sure that those issues are dealt with as quickly as possible," she said.

"We set up this parliamentary inquiry to get to the bottom of 40 years of Fiskville, it's a very large exercise.

"People have been doing their work very assiduously, but I absolutely hear what the committee is saying and we'll make sure that all of the documents that need to get out, get out."

In its interim report tabled in June, the committee said firefighters and staff who wanted records from the CFA and other government agencies should be given access "without hindrance".

The CFA closed Fiskville in March, as a result of water testing that detected elevated levels of the chemical PFOS.

The committee is yet to hear evidence from the CFA, the MFB, the Environment Protection Authority and WorkSafe.
