The South Cathkin site, on the edge of Glasgow in South Lanarkshire, has been operated by the city council since the 1990s.
Rubbish stopped being dumped in the landfill site in August when planning permission expired.
A bid to extend the life of the site until 2016 was thrown out by South Lanarkshire planners in April. They set a tight deadline for the area to be restored.
The city council appealed to the Scottish Government against the timescale and the refusal to grant an extension.
Glasgow argued it needed to continue using South Cathkin until its new £154million recycling and renewable energy centre opens at Polmadie.
It also insisted it would not be able to meet the timescale set by South Lanarkshire for restoring the site.
The Scottish Government appointed a Reporter to hear both sides of the argument and decide on the site's future. Both councils were originally told a decision would be made by October 8 but the date was pushed back.
It has now been revealed a hearing will be held on Thursday October 24 in the Murray Owen Centre in East Kilbride.
The Reporter will hear from South Lanarkshire, the city council and local people and is expected to announce the decision on January 14.
A Glasgow council spokesman said: "The city is currently transforming the way it deals with waste and over the next few years, Glasgow's use of landfill will decrease dramatically.
"In the meantime, the city still requires some capacity and has been investigating options including extending the operating life - but not the size - of its existing South Cathkin site."
Michael McGlynn, South Lanarkshire head of planning and building standards, said: "Planning permission to extend operations at South Cathkin Landfill site, until August 2016, was refused at a meeting of the South Lanarkshire planning committee on April 16 this year.
"The appeal hearing into Glasgow City Council's appeal against this refusal will be heard on October 24 in East Kilbride. The Council looks forward to presenting its position to the Reporter."
