A special meeting is taking place today to decide whether controversial plans for Llanbedr Airfield in Snowdonia National Park should be approved.
The National Park Authority planning committee is considering proposals from the owners of the airfield to turn the unused former military airbase into an aircraft maintenance and disassembly operation.
Llanbedr Airfield Estates LLP claims that the new business could create up to 50 jobs in the area.
But, worried that the new plans would impact upon the National Park's landscape, the Snowdonia National Park Society had requested a full environmental report into the proposals.
Llanbedr Airfield was opened in the 1930s as a military facility. It had 130 staff when it closed down in 2004.
Plans for the airfield include the creation of an aircraft engineering and maintenance training school.
Ffestiniog, Llanfair, Harlech, Maentwrog, Talsarnau and Dyffryn Ardudwy and Talybont Community Councils have given their support for the project, and the Environment Agency has no objections.
If the plans are approved, aircraft would be disassembled and cut up with light machinery and hand tools, with the reusable parts stored on-site and then removed after 3 weeks.
Scrap metal from the planes would either be crushed into bales or kept in larger segments and transported off-site.
The planning report states there would be between 8 and 12 aircraft parked at any one time on the airfield, but this could rise to 20 in certain circumstances.
The report also said that noise levels would 'be as expected as at any operational airfield- greatest when engines are being tested, or during take off and landing operations, estimated to be of 30 minutes duration.
