Louth GAA's grounds committee chairman Aidan Berrill has said the proposed new ground for the county will not be open to other sports, despite calls from Dundalk FC to be included.
A 14,000-capacity stadium is being proposed by Louth GAA, with plans submitted to Louth County Council.
Last September, GAA delegates voted to build a new €12 million stadium on the outskirts of the town.
The 10-acre plot was purchased by Louth GAA for €400,000 from the council.
A forthcoming fundraising raffle draw could raise up to €2m if successful.
Lilywhites chief executive Mark Devlin wrote in a recent match programme saying: "As someone who doesn't have the historic baggage of any disputes between sports, I would hope that any new stadium in the town would be for the benefit of all our community and all sports played in the county.
"There may be reasons why it wouldn’t work but I believe that we owe it to the public to explore all possibilities. It is definitely something I will be looking to discuss and understand what may be achievable."
But Berrill has said that will not happen.
"This is purely a GAA venue. It will be built by the works and contributions of the GAA - Croke Park and Louth GAA ourselves," he told the Dundalk Democrat.
"We’ve done our homework with Louth County Council. It’s not just something that’s happened in the last few months, it has been ongoing for quite some time.
"We tried to develop the Gaelic Grounds and we tried to develop the DkIT grounds about seven or eight years ago. Unfortunately, they fell apart, but this is a serious proposition now. We’re going ahead with this and it’s for the benefit of Louth GAA Gaels.
"The Dundalk chairman, I believe, was on LMFM and said he’d been in touch with Louth GAA, and that nobody had come back to him. That’s news to any of us. There has been nobody in touch with us in relation to whatever."
Under GAA rules, the use of county grounds for other sports can be sanctioned by Central Council but only "in exceptional circumstances", which director general Tom Ryan said earlier this year would only be for events considered of national significance
