Winter Service Introduction This Policy identifies and outlines the plans and procedures for the delivery of
Highway Winter Services within the Borough of Doncaster. 1. Objectives and limitations. 1.1. Objectives
To provide a winter service, which, as far as is reasonably financially
affordable and physically practicable, will:-
a. permit the safe movement of vehicular and pedestrian traffic on the
adopted highway network,
b. reduce the impact of the weather conditions on the national and
local economy by maintaining movement of traffic and pedestrians,
c. minimise delays and incidents directly attributable to the adverse
weather conditions.
1.2. Limitations.
Given the scale of the financial, physical and other resources involved in
delivering the Winter Service, the variety of weather conditions that may be
encountered and the difficulties in maintaining high levels of plant utilisation for
specialist equipment, it is not practically possible to:-
a. provide the service on all parts of the network; or
b. ensure running surfaces are kept free of ice or snow at all times,
even on the treated parts of the network.
2 Safety, Serviceability and Sustainability 2.1 Safety
Winter Service Operations are essential for public safety. The carrying out of
various salting activities and clearing the highway of snow help to achieve this
together with advising the public on travelling in winter and self -help.
S:\Highways\Maintenance\PT\WMAINT\2019-20\policy\I4-winterpolicy no markup.doc
Page No. 2
2.2 Serviceability
Maintaining the availability and reliability of the highway network is a key
objective for the Winter Service. It is one where the user judgments of
performance are immediate rather than longer term.
2.3 Sustainability
Low temperatures and the formation of ice can cause serious damage to
the fabric of running surfaces. Winter Service operations can therefore make
an important contribution to whole life costs and performance of the highway.
The environmental impact of the service can be minimised by the appropriate
use of materials, vehicles etc.
3 Legislation and Guidance Legislation and guidance supporting the provision of winter service is that
relevant to England, provided by the following Acts, Codes of Practice,
Regulations and guidance:-
3.1 Acts:-
3.1.1 Highways Act 1980 Section 41 and 150
The Highway Authority has a duty to clear highways of obstructions due to snow
as well as taking reasonable precautions to keep the carriageway and footways
free of ice.
3.1.2 The Railways and Transport Safety Act 2003 Section 111 (highways:
snow and ice)
After section 41(1) of the Highways Act 1980 (c.66) (duty of highway authority to
maintain highway) insert: - “(1A) In particular, a highway authority is under a
duty to ensure, so far as is reasonably practicable, that safe passage along a
highway is not endangered by snow or ice.”
“This is not an absolute duty, given the qualification of ‘reasonably
practicable’, but it does effectively overturn previous legal precedence, albeit
not with retrospective effect. Section 150 of the Act still imposes a duty upon
authorities to remove any obstruction of the highway resulting from
S:\Highways\Maintenance\PT\WMAINT\2019-20\policy\I4-winterpolicy no markup.doc
Page No. 3
‘accumulation of snow or from the falling down of banks on the side of the
highway, or from any other cause'.
3.1.3 Traffic Management Act 2004 – Network Management Duty
Part 2 of the Act places a network management duty on Local Traffic
Authorities. Section 16 (1) states:
“It is the duty of a local traffic authority to manage their road network with a view
to achieving, so far as may be reasonably practicable having regard to their
other obligations, policies and objectives, the following objectives:
(a) securing the expeditious movement of traffic on the authority’s road network;
and
(b) facilitating the expeditious movement of traffic on road networks for which
another authority is the traffic authority.”
3.1.4 Health and Safety at work Act 1974.
DMBC Risk Assessments.
3.2 Codes of Practice:-
3.2.1 Well managed Highway Infrastructure – a code of practice
3.3 Regulations:-
3.3.1 Working time regulations.1998
3.3.2 Drivers hour’s rules
3.4 Guidance:-
3.4.1 National Winter Service Research Group Guidance. (NWSRG)
3.4.2 The resilience of England’s Transport system Oct 2010. (DfT)
3.4.3 Winter Service guidance for local authority practitioners. (UKRLG)
3.4.4 DMBC Winter Service operational document

Priorities and treatments. 5. Carriageway Network 5.1 Carriageway Priorities and treatments.
Network Priority
Description Precautionary Treatment
1 Comprises the Strategic
Network and Primary Route
Network. (See Appendix A2).
Precautionary salting or salting for
the treatment of ice shall be
undertaken whenever necessary.
2 & 3 Comprises other ‘A’ class
roads ‘B’ roads, some ‘C’
class roads and other roads
providing main traffic links in
urban areas and serving
industrial estates.
These roads shall be treated in the
same way as, Priority 1 roads.
Treatment of priority 1, 2 & 3
networks may be combined for
treatment.
4 This network covers urban
and rural link roads, other
well-used roads and most
roads served by bus services.
(Secondary routes)
These roads shall not normally
receive precautionary salting and
will be salted only in periods of
severe weather*(see sec 19). if the
gritters are not required to deal with
Priority 1, 2 and 3 roads.
5 Comprises the remainder of
the rural/urban network.
As Priority 4 roads but following
their treatment.
S:\Highways\Maintenance\PT\WMAINT\2019-20\policy\I4-winterpolicy no markup.doc
Page No. 6
5.1.1. Requests from emergency services.
Requests from the emergency services for localised treatment of the highway
due to accidents or similar shall be actioned. (all relevant details must be
recorded.)
5.1.2 Requests for a street(s) to be added for priority 2, 3 or 4 treatments.
Any requests for additions to the priority 2, 3 or 4 network schedules will be
considered against the following criteria: - Usage type and numbers, local
climate, available alternatives, recent changes in network layout or usage and
the availability of physical and financial resources. (This salting network review
will only be undertaken during the pre-winter planning stage each year).
5.2 Treatment operations.
i. For precautionary salting the priority 1, 2 & 3 networks are normally treated in
a combined manner in order to optimise the efficiency of the salting operations.
(See plan at appendix A3)
ii. On occasions, dependant on forecast weather conditions the Priority 1
network may be treated independently due to working / duty hours’ time
constraints.
iii. Should issues occur beyond the control of the authority, it may on occasions,
be necessary to reduce network treatment or the treated network. Should such
a situation arise treatments may be reduced to either Priority 1 or Priority 1 & 2
roads. (Subject to discussions with senior management prior to any
implementation - see 24.2.3)
iv. Where time, resources and working hours permit, and it is expedient to do so
all or some the Priority 4 carriageway network, may, in advance of forecast
severe weather*(see sec 19), receive some pre-treatment.

8. Treatment for Snow Conditions
8.1 Carriageways
Snow clearing / ploughing will not usually commence until the snow depth
exceeds 25mm with further amounts of falling and settling snow expected.
Ploughs shall be set to clear all possible snow from the carriageway surface
and shall follow any specific guidance contained in the operational details.
Note: - Pre-salting carried out in advance of snow and the action of traffic
thereon greatly assists in the dispersal of lying snow.

9. Salt Bins
9.1 Provision
Salt bins can be a useful addition on the network if placed in appropriate
locations, managed, serviced and utilised. It is unrealistic to place out bins in
such numbers that they cannot be serviced and refilled when needed most.
Salt bins may be provided on, and for use within, the public highway where
certain criteria are met.
9.1.1 Carriageways
i. At sites on the public highway where the vertical or horizontal profiles
are such that problems for the public may be foreseen and they are not
on a Pr 1, Pr 2 or Pr 3 precautionary treatment route. (a vertical profile
will normally need to exceed a gradient of 10%).
ii. On precautionary treatment routes only where previous experience has
shown a particular risk.
9.1.2 Footways
i. Where requested to help facilitate treatment on footways, these will be
considered alongside those for carriageways.
9.1.3 Assessments
I. Given the number of requests for salt bins and the need to ensure
a holistic approach to this area of the service, all current salt bins
and requests for new bins will be subject to an annual review and
a scored site assessment.
9.2 Removal.
i. Salt Bins at locations that are subject to repeated vandalism or
complaints will be removed.
S:\Highways\Maintenance\PT\WMAINT\2019-20\policy\I4-winterpolicy no markup.doc
Page No. 13
ii. Salt bins will be removed where network changes etc. are carried out,
and the risks alleviated or removed, resulting in a reduced assessment
score.
9.3 Location
i Salt bins wherever possible shall be sited away from trees, hedges,
grassed areas and watercourses etc. for environmental reasons.
ii Bins shall only be located where they may be used safely and will not
impede / obstruct the use of the highway.
iii. For practicality and efficiency, salt bins will not be located closer than
250m to each other.
9.4 Maintenance
i Bins will be checked, replaced, filled as necessary prior to the start of
‘high’ winter period and refilled as necessary subject to available
resources until the ‘high’ winter period is over.
ii unless otherwise specifically identified, salt bins will remain on site outside
of the winter period.
10. Winter Standby Period
10.1 The winter standby period will be determined annually.
In general it will be from the 1st Monday in November until the 2nd Monday in the
following March. These start and finish dates may vary from year to year
dependant on the seasonal forecast conditions and will be agreed with the
Head of Service for Waste and Highway Infrastructure.
S:\Highways\Maintenance\PT\WMAINT\2019-20\policy\I4-winterpolicy no markup.doc
Page No. 14
10.2 A stand-by system will be operated which ensures drivers and supervisors
will be available as far as is reasonably practicable, to carry out precautionary
salting activities within the constraints of duty, driving hours and working time
directive(s).
It is anticipated that under normal circumstances one evening action and / or
one morning action will suffice.
10.3 It should be noted that there might be, on occasions, due to legislation on
duty hours when precautionary salting cannot be undertaken at the most
appropriate time reflective of the prevailing weather conditions.
11. Vehicles and Plant
11.1 Gritting Vehicles
11.1.1 A range of demountable and purpose built vehicles and pedestrian units
will be maintained for gritting purposes. (See section B5 in the
operational document)
11.2 Calibration and Monitoring 11.2.1 All vehicles shall be calibrated prior to the start of the winter season
giving consideration to the materials being used and the manufacturer’s
specifications and recommendations. Vehicles shall be monitored during the
season for any signs of deviation from correct operation. Any suspected
operating problems shall be reported and re - calibration or maintenance shall
be carried out as necessary.
11.3 Other Plant
11.3.1 Additional plant and drivers may be hired in as necessary from local
plant hire companies; farmer’s etc.

Managed Highway Infrastructure.
12.2.2 The Highway Duty Officer who is on duty ‘24/7/365’ will make decision(s)
on any action(s) required ‘out of office hours’ on a daily basis (or more
frequently as may be necessary) in conjunction with the Highways Maintenance
Office. Any ongoing monitoring of conditions will be carried out as necessary.
(See section B8 in the operational document)
12.2.3 Initial decisions will normally be made by 13:30 Hrs each day for planned
action during the period 15:30 to 07:30 hrs.
12.2.4 Decisions on any action required during the working day will be made by
the highway maintenance office in discussion with the Highways Duty Officer.
12.2.5 Decisions on any action required or not as appropriate will be
communicated to operational staff and managers by email or other electronic
means and advised to adjacent local authority’s key contacts and emergency
services for information.

12.3. Decision Recording
12.3.1 All decisions, action or no action, shall be recorded on the appropriate
forms.
When the road surface temperature (RST) is forecast to be ps. 3 degrees C or
lower or snow is forecast, a full record supporting the decision shall be
documented.
12.4 Decision Support Systems.
12.4.1 A decision support system and supporting information shall be available
to assist the Duty Officer. This will include all those marked ***and all or some
of the remainder.

16.5 Effectiveness of Salt
16.5.1 Low temperatures
It should be noted that rock salt starts to become less effective when the
temperature falls below minus 5° C and below minus 11° C salt becomes
virtually ineffective.
16.5.2 Low humidity
Where conditions with Low Humidity occur consideration should be given to
additional later treatments.
16.6 Materials for Severe Conditions
During severe or prolonged conditions sand, grit etc. (which acts as an
abrasive) may be used to augment supplies and assists in the breakdown of
any ice that may have formed.
A De Icing liquid with additives may be used for treatment as appropriate.
17. Publicity and Public Contact points
17.1 Publicity
Information on the winter service provision shall be made available to the public
via press releases and the DMBC internet web site. Social media sites i.e.
twitter or similar may also be used to advise once treatments are complete and
when other activities such as snowploughing are in progress.
17.2 Contact.
Enquiries to the council may be made via the Council contact centre on 01302
736000.

18. Works for outside bodies / other departments.
18.1 Works will only be undertaken for other council departments if resources
are available and they are not required for works on the public highway. Any
agreed works to be carried out would only be done on a fully rechargeable
basis.
18.2 Works for external or private bodies will not normally be undertaken.
18.3 Reciprocal arrangements with adjacent local authorities will be put in place
where both parties agree and such arrangements have a beneficial outcome
with regards to efficiencies and network continuity provision.

Road and weather conditions that might normally be expected during the
winter period. (this includes frosts, rain, winds, light snow etc.)
10. Severe Weather
Defined as ‘widespread ice or snow (not frost) is present on the network for
more than 24 hrs with a forecast for road surface temperatures not to rise
above zero for a further 24 hrs.
11. Extreme Conditions
When factors outside the control of the authority affect the ability of the
authority to deliver, its pre-determined policy in normal winter conditions or
weather conditions themselves are declared as such.
20. Action during extreme conditions
Determination of requirement to vary operations.
Where due to circumstances outside of the control of the Authority it is
recognised that continuing action in accordance with the pre determined policy
cannot be maintained, treatment shall be reviewed and tailored in discussion

21. Resilience – Salt stocks
In endeavouring to ensure adequate provision has been made throughout the
service in respect of resilience the following should be considered as
‘necessary’.
Resilience stock levels recommended are as shown in the table below.
Precautionary network Treatment:
Days Runs /day (No)
Spread rate (g)
Tonnes / run Total (Tonnes)
1st marginal period 2 2 15 60 240
