Plans for a new ambulance station in Drogheda remain without a confirmed timeline, with the HSE saying it has not yet identified a suitable site.
The proposed development is intended to replace the current ambulance base on the grounds of the Cottage Hospital, where paramedics have raised concerns for several years about the condition and size of the building.
Staff have reported problems including damp, leaks, cracks in walls and limited space, and have been calling for a modern replacement facility.
The issue was recently raised with the HSE by Sinn Féin TD Joanne Byrne.
In response to a parliamentary question, the HSE said it is carrying out a detailed assessment of possible locations for a new base, taking account of cost, location, site size and planning requirements.
The HSE said a large site is needed, but finding one has proved difficult because of issues including availability, zoning, access to key infrastructure and the possible impact on nearby communities.
It said zoning remains one of the main obstacles in identifying a suitable option.
Over the past two years, the HSE has carried out an extensive options appraisal and has engaged with local authorities and IDA Ireland as part of the search.
However, it said no site considered so far has met all of the operational, planning and financial requirements.
The HSE added that it is continuing to work with the National Ambulance Service and other relevant bodies to identify a viable location.
Because of the difficulties involved, it said it could not provide a definite timetable for the project at this stage.
A local paramedic said staff were disappointed by the latest update and feared the development was being pushed further into the future.
They said crews would continue to carry out their work for the people of Drogheda despite the conditions at the current base.
