A planning application for a service station adjacent to the site of the Creeslough tragedy is to be lodged by the owners of the original site on which ten people died in October 2022.
The new application will be lodged by the Lafferty family with Donegal County Council in the coming days
The site is adjacent to the original site on which the explosion occurred.
The application will include permission to demolish an existing house on the site of the planned new development.
It will also seek permission to build an extensive new service station on the new site.
The proposal includes a new building that will incorporate a shop, post office, off-licence, deli, toilets, staff facilities and a forecourt.
The application also refers to underground storage tanks and pumps, a car wash facility, an outdoor launderette kiosk, an ATM machine and various signage.
The intended planning notice was lodged in a local newspaper.
The new application comes five months after An Coimisiún Pleanála overturned planning permission for a new filling station on the same site as the original explosion.
Donegal County Council granted permission to Vivo Shell Limited to redevelop a service station and shop at the site in February.
That decision was appealed by a number of family members of those killed in the October 2022 blast.
On turning down the application for a new building, An Coimisiún Pleanála said the proposed plan was "out of character" with its surroundings in the village.
The planning body said: "Having regard to the existing character and the prevailing pattern of development in Creeslough, it is considered that the proposed development (as amended), by reason of its overall architectural treatment, scale and design, would be out of character with its surroundings, would seriously detract from the architectural character and setting of Creeslough and the streetscape and approach from Letterkenny generally.
The proposed rebuild had allowed for the demolition of the existing building where the explosion occurred and the construction of a new structure that includes a shop, post office, deli, off-licence and fuel forecourt.
A memorial garden and light-based sculpture with ten metal poles commemorating those who perished in the tragedy was also planned for the site.
However, many of the families who lost loved ones in the tragedy said this was an insult to the memory of their relatives, considering they died in the metal and rubble of the blast.
The land on which the original service station was built is still owned by the Lafferty family.
Last month, a motion was passed by Donegal county councillors seeking a compulsory purchase order on the site of the tragedy.
Cllr Tomas Sean Devine brought the motion forward ahead of the third anniversary of the tragedy.
He called on the council to start proceedings to take ownership of the land where the explosion occurred, by way of negotiation with the owner or a Compulsory Purchase Order (CPO) and sit down with the families and design a memorial garden in memory of all those affected.
Four men, three women and three children, ranging in age from five to 59, died in the blast that ripped through the service station in the village and a nearby apartment block on 7 October 2022.
Those who died were: Robert Garwe and his five-year-old daughter Shauna Flanagan-Garwe; Catherine O'Donnell and her 13-year-old son James Monaghan; Jessica Gallagher; Martin McGill; James O'Flaherty; Martina Martin; Hugh 'Hughie' Kelly; and 14-year-old Leona Harper.
The new planning application for the new site will be lodged with Donegal County Council in the coming days and can be viewed or purchased by the public.
