Winter Service Policy The aim of this winter service plan is to set out how Sligo County
Council will deal with ice and snow conditions on roads in County Sligo. The
winter service plan will be amended as necessary during the winter season.
The purpose of this Plan is to identify the processes, procedures and key
personnel employed by Sligo County Council to deliver the winter service for
County Sligo. In general planned treatment responses involve spreading salt
on the road during frost and ploughing snow during snow periods.
Winter service is not an emergency service in the traditional sense in that low
temperatures, ice and snow are regular, frequent and reasonably predictable
occurrences.
This plan does not deal with other extreme winter weather events such as
flooding and high winds.
The Council’s objective is to provide an effective and efficient winter
service within the resources available to minimise the negative impacts
of frost, ice or snow on the travelling public, i.e.
Allow the safe passage of vehicles and pedestrians on Priority 1
(National Roads) and Priority 2 Roads
Minimise delays due to winter weather conditions
Ensure operations are undertaken safely and efficiently
The level of service will vary with the priority assigned to a particular route
e.g. Priority 1 roads will be given a higher priority than priority 2 roads etc.
The aim is to treat the strategic locations on the public road network including
roads serving;
- Hospitals & Clinics
- Local Authority Salt Stores
- Emergency Services (Fire & Ambulance Stations)
- Roads serving Water and Sewage Treatment Works
- Major Industries
- Sligo Bus / Train Stations
- Sligo Airport
Most of the roads serving the above locations are listed as Priority 1 and
Priority 2 routes. Given the scale of the resources involved in delivering the
winter service it is not possible to provide the service to all parts of the roads
network. It is not possible to ensure that road surfaces are kept free of ice or
snow at all times on the treated parts of the network.
Winter maintenance on national roads is carried out by Sligo County
Council for the NRA and is funded by the NRA. Winter maintenance on Non
National Roads is funded by the Department of Transport and Sligo County
Council.
The winter maintenance season is from Monday 19th
October, 2015 to
Sunday 1st May 2016. All of the above is subject to the availability of
resources. Resources include finance, salt, plant and labour.

Winter Servicing Prioritisation of Roads & Routes
The winter servicing of the road network in Sligo is prioritised considering the
strategic importance of the roads, the volume of traffic on the roads and roads that
are important to the region.
The NRA Winter Service Working Draft Manual suggests the following criteria
for the prioritising of routes.
Table 1 - NRA Criteria for Prioritising Routes
Road
Priority
Description Level of Service
Priority 1
Those routes which are essential to be kept
serviceable in all weather conditions, as far as
reasonably practicable
To be treated during all weather events
Priority 2
Those routes which are desirable to be kept
serviceable in the normal winter weather
conditions, as far as reasonably practicable.
Priority 2 routes could include those routes
which are important regionally, such as (for
example) principle public transport routes, or
the main commuter routes.
To be treated as part of the normal winter service but
may have interruptions to treatment in certain severe
weather events.
Priority 3
Those routes that could be kept serviceable
once Priority 1 and 2 routes have been treated,
if resources allow.

Mobilisation Time 1 hr 1 hr When possible
Treatment Time 2 hr 3 hr When possible
Precautionary treatment is when salt is spread following warnings of expected low
temperatures to reduce the likelihood of ice forming on the road.
Sligo City Centre footpaths will not be considered for treatment except in severe or
prolonged winter weather and then only when resources are available.
During extreme cold periods and during snow the Machinery Yard staff will be
helped by the Roads Area staff. Plant and additional hired mechanical
spreaders/drivers will also be used for getting grit and salt onto the roads
particularly on hilly local roads, roads near schools and roads where traffic is
6
encountering problems due to the weather.
Sligo County Council ordinarily treats 440km approx. of road which equates to
100% of the National Primary network, 100% of the National Secondary network,
100% of Regional roads and 48km approx. of the local/urban road network.
Route F treats 42 km approx. of roads within Sligo City and its Environs – see
map.
Weather Predictions and the Decision Process
The NRA procures bureau weather services to assist Sligo County Council and the
other Local Authorities in predicting when frost, ice or snow may occur on the
road network. These services are currently provided by a combination of Met
Éireann and Vaisala.
The weather forecast information (supplied by Met Eireann) and the weather
station measurements (from Vaisala) are available to the On Call Duty Engineer.
There are two weather stations in County Sligo.
(i) On the N4 described as the “N4 Collooney Bypass” Weather Station (at
Drumfin South of Collooney).
(ii) On the N16 described as “N16 Manorhamilton” Station (at Gortnagrelly –
between Sligo and Glencar). This station was damaged in a car accident in
2014 and has not yet been replaced.
Duty Engineers have access to other weather station information in
neighbouring counties e.g. in Mayo on N59 between Ballina and
Crossmolina, on N5 near Charlestown and on N61 near Elphin and at
Tullaghan on N15.
The Duty Engineer will review the weather forecast information each day. Based
on the forecasts the Duty Engineer will make and record the treatment decisions
for the evening and the following morning.
The Duty Engineer will continue to monitor weather as necessary, particularly
when the forecast is marginal. This may change the previously planned decision
depending on weather trends.
Precautionary evening treatments will generally commence after 7.00pm.
However, this time may change dependant on weather conditions. If it was
raining, treatment would not commence until the rain stops.
Table 5 (from the NRA Working Draft National Winter Service Manual) sets out a
decision matrix guide for salting operations.

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.
Organisation Arrangements and Personnel
Duty Engineer
The Duty Engineer on reaching a decision about salting will inform the Technical
Services Supervisor, Machinery Yard and give details of the routes to be salted,
the spread rate of salt and the proposed starting times. The Technical Services
Supervisor, Machinery Yard will in turn notify/call out the Machinery Yard
drivers rostered to salt the routes and give them the salting details.
The Technical Services Supervisor, Machinery Yard will arrange to have a
loading shovel and driver available to reload the salters after the routes are salted
in order to be ready for the next roster.
During periods of extended winter service activity the Machinery Yard Technical
Services Supervisor and Senior Executive Engineer, Machinery Yard will assess
driver and operator fatigue prior to assigning duties.

Road Salt / De-icing Material
The NRA has procured salt for the 2015/2016 season and operates the Salt
Management System.
Sligo County Council arranges to collect the salt from the NRA depots.
Rock salt is the most commonly used de-icing material. Marine salt is also readily
available and is also suitable.
Rock salt should comply with BS 3247:1991 ‘Salt for spreading –
Coarse Rock Salt’.
Grit (salt sand mix) should not generally be used in the salt spreaders,
because of the excessive wear on equipment, except in the treatment of
hard-packed snow and ice which cannot be removed by ploughing.
The salt is stored in the covered salt barns at Drumaskibbole at the Machinery
Yard and at Union Quarry. Salt will also be stored outdoors (covered) at a depot
at Union Quarry if necessary.
Table 8 shows the approx. salt used on each route spreading at 10g/m2, 20g/m
2 and
40g/m2.

Depots/Salt Barns
Sligo County Council has roofed Salt Barns at:-
(a) The Machinery Yard in Drumaskibbole. This was constructed in 2009. It is
located adjacent to the N4 Dual Carriageway and is very convenient for access to
all routes.
(b) Union Quarry - with a capacity of 1300 tonnes.
In addition there is an uncovered salt storage facility/depot at Union Quarry which
has reinforced concrete walls and floors. The salt is covered with a proprietary
cover suitably tied down-to prevent salt getting wet. It holds 900 tonnes of salt
approx.
Welfare facilities are available for staff at the Machinery Yard and at Union
Quarry.
Details of the Sligo County Council salt depots are shown in Table 9.

The roofed salt barns at Drumaskibbole and Union Quarry will be filled to capacity at
the beginning of the season and again prior to the Christmas shutdown if
salt is available.
As salt is removed from stockpiles a safe slope on the salt must
be maintained to protect operatives from the risk of collapse of the stockpiles.
Pre Season Preparation
Pre-season preparation is very important. This includes the following:
Refresher training for drivers and finalising routes.
Refresher training for Duty Engineers.
Calibration of Salt Spreaders.
Servicing of Plant i.e. lorries, salt spreaders and snow ploughs.
Ordering of Salt through NRA Salt Management System.
Preparation of depots including checking lighting.
Check weather station operation and website access.
Check snowploughs and test attachments to trucks.
Check stock of salt spreader spare parts.
12
Communication & Publicity
The communication of road conditions especially during severe cold/snow spells
to the public is very important. Sligo County Council will use the broadcast and
print media and its own website to inform the public about road conditions and the
Council’s Winter Service Plan.
The salting route maps are posted on the Sligo County Council website for
the duration of the winter season including summary information from
the service plan.
During severe or prolonged cold weather the Council website will contain
frequently updated information on road conditions in the County. Updates and
progress reports will be issued on a regular basis to the local radio stations and
newspapers about the road conditions. Sligo County Council advertise emergency
contact numbers to deal with out of office time enquiries.
