Annual Winter Maintenance Plan

Here are some of the higlights of the Winter Maintainence Plan for 2021/2022 but the full document is available here.


Leitrim County Council will, during severe weather, clear snow/ice from footpaths at strategic locations in the towns and villages. Property owners are encouraged to clear snow from the footpaths outside their property. We will advise the public of the best equipment to use and the safest way to use this equipment in clearing snow from footpaths.

Covid 19 Policy

All workers are to protect themselves from risk of infection from other workers by following Leitrim County Council’s Health & Safety policies, (including all Standard Operating Procedures & Guidance), on COVID-19.  The RASOP for people entering the trucks should be strictly complied with. The trucks should be cleaned, (all surfaces wiped down etc.), and the cab disinfected every time a driver finishes their shift, and when there is a change of personal. On completion of a shift, (or at least once per week if only one driver has been in the vehicle during that period), or at anytime when there is a change of driver, the vehicle should be disinfected using the disinfectant spray. When a vehicle is disinfected, it should not be entered for a 20-minute period after the disinfectant is administered. This disinfectant spray should be used in conjunction with the regular cleaning and wiping down of surfaces, and not to be solely relied on.

Should a driver of a vehicle or any other staff member that has been in the vehicle test positive for the virus, then the plant manager should be notified immediately, so that the vehicle can be professionally deep-cleaned. Nobody else should enter the vehicle until this has been undertaken.

Weather Monitoring and the Treatment Decision Process

Leitrim County Council appoints Duty Engineers to review the weather conditions and make a decision on the treatment to be carried out, each day during the winter period. The weather predictions are made available to Leitrim County Council through the TII web based weather application provided by Met Eireann and Vaisala. The Duty Engineer will monitor the weather conditions as necessary and alter any decisions made as required.

Winter Service Duty Engineers and Winter Service Supervisors must attend to their normal Council duties during normal Council working hours and be competent to do so. Accordingly, Leitrim County Council acknowledges that there is a limit to the extent of overnight monitoring that can be expected of a Duty Engineer. In particular, the Council would expect that treatment decisions would normally be communicated to the Winter Service Supervisor before 22:00 hours. If the treatment decision is deferred to a later time, the Duty Engineer should advise the Winter Service Supervisor of the deferred treatment decision deadline at or prior to 22:00 hours.

The decision to undertake precautionary treatments should be, if appropriate, adjusted to take account of residual salt or surface moisture.

All decisions should be evidence based, recorded and require careful monitoring and review.


(a)   Particular attention should be given to the possibility of water running across carriageways and other running surfaces e.g. surface water off adjacent fields after heavy rains, washing off salt previously deposited.  Such locations should be closely monitored and may require treating in the evening and morning and possible other occasions.  Ideally the source of the run-off should be diverted from the roadway.

(b)   When a weather warning contains reference to expected hoar frost, considerable deposits of frost can occur.  Hoar frost usually occurs in the early morning and is difficult to cater for because of the probability that any salt deposited on a dry road too soon before its onset, may be dispersed before it can become effective.  Careful monitoring is required under this forecast condition which should ideally be treated just as the hoar frost is forming.  Such action is usually not practicable and salt may have to be deposited on a dry road prior to but as close as possible to the expected time of the condition.  Hoar frost may also be forecast at other times of the day, in which case the timing of salting operations should be adjusted accordingly.

(c)   If under these conditions, rain has not ceased by early morning, crews should be called out and action initiated as rain ceases.

(d)   Under these circumstances rain will freeze on contact with running surfaces and full precautionary treatment should be provided even on dry roads.  This is a most serious condition and should be monitored closely and carefully throughout the danger period.

(a)   Rate of spread for precautionary treatments may be adjusted to take account of variations occurring along the route such as residual salt, surface moisture (in the air or on the road surface) and traffic density.

(b)   All decisions should be forecast based, recorded and require careful monitoring and review.

(c)   Ice refers to all ice on the road surface, including black ice.

(d)   For salt stored outside it may be necessary to increase spread rate for precautionary treatment salting from 10gm/m2 to 15gm/m2. Duty engineer to decide which rate to use.

Materials and Spares

The Area Engineers / Plant Manager will be responsible for re-ordering de-icing materials. The new procurement in operation by the TII will be used for procuring salt this winter. There are small quantities of fuel stored at each Depot for emergencies, but the majority of the fuel will be acquired at Retail outlets. Spare parts for winter service machinery are stored in the machinery yard. The Machinery Yard supervisor will be responsible for reordering stock.

Community Involvement

During severe weather conditions Leitrim County Council will make available grit at 43 locations throughout the county to enable people in the community to use it to treat local roads, hills etc that we are never going to be able to get to due to the demand on our resources. See Appendix A for map and a full list of the locations of the drop points (as per "Grit Allocations" web page or the last page on the Winter Maintenance Plan 2021 / 2022). This grit is available for any person to use. They will not be working for Leitrim County Council when spreading this grit.

Leitrim County Council have introduced a scheme where residents associations and business can purchase from the council a salt bin and salt for their housing estates or business premises. They will be charged a nominal fee. Depending on our resources at the time the bin will be refilled by us or salt made available to the residents at our depot, for a nominal fee, see our "Request for Salt Bin" page by clicking here.
