The organisation is tasked with considering the GDF proposal, as well as issuing £1m of funding a year to community groups in areas earmarked as a potential site.
Mid Copeland is one of two sites shortlisted across the country.
The other is in South Copeland and the search area includes the electoral divisions of Millom and Millom Without.
The Mid Copeland Community Partnership said a GDF would require both a suitable site and a willing community, with processes to identify those and acquire the necessary permits set to take about 15 years.
The GDF design considered would see waste buried under the sea, with an overground facility on or near the coast to provide access to it.
