United Energy report UE RP 2804 Electricity Safety (Electric Line Clearance) Regulations Compliance Obligations reviews the Electricity Safety (Electric Line Clearance) Regulations 2015, identifies United Energy’s compliance obligations and provides evidence of compliance.
8 Service Area Characteristics
The purpose of this section is to describe the UE geographic area in sufficient detail to provide an appreciation of the vegetation management issues associated with UE’s operating environment.
UE is a regulated, Victorian electricity distribution business that was established in 1994 as result of the dis-aggregation of the State Electricity Commission of Victoria, and the amalgamation with Box Hill and Doncaster Municipal Electricity Undertakings.
UE’s electricity network is largely urban. It covers 1,472 sq.km and serves customers throughout Melbourne’s south-eastern suburbs, and the Mornington Peninsula. It includes about 600,000 residential customers, 56,000 business customers, and 4,000 commercial and industrial customers (96 take supply at high voltage), with total demand of 7,700 GWh.
The UE electricity distribution network facilitates the transport of electrical energy from ten, Ausnet Services’ terminal stations to UE’s 47 zone substations, 13,200 distribution substations and eventually onto the 660,000 customers.
ELECTRIC LINE CLEARANCE MANAGEMENT PLAN 2017/18
Document Number: UE PL 0010
Version 5.0 – September 2017

The northern part of the service territory is urban with a mixture of residential and commercial customers, located entirely within the Melbourne metropolitan area, bordered by Port Philip Bay and other urban areas. The southern part of the service territory is a mixture of developed and undeveloped land. It includes the city of Dandenong, and the city of Frankston which is located on the southern rim of the Melbourne metropolitan area and the gateway to the Mornington Peninsula.
The 720 sq.km Mornington Peninsula separates Port Phillip Bay and Western Port Bay, and is bounded by Bass Strait. It represents 50% of UE’s territory, with a coastal boundary of over 190 km.
Temperatures across the region range from a low of -3 degrees C to high of 46 degrees C, an average rainfall of 650mm across 150 rain days, with winds mainly from the south west quadrant with maximum wind gusts up to 120km/h.
The number of total fire ban days per year across the region (central district), for the period 1986-2015), varied from one to seven.
United Energy distribution region
Although geographically small (about one per cent of Victoria’s total land area), the UE electricity network supplies 24% of Victoria’s electricity customers, across 8% of Victoria’s power lines (12,800km) supported on 16% of Victoria’s power poles (215,000). About 20% of the network is underground (2,600km), and 80% of the network is overhead (10,200km) with 110,000 public lighting lanterns and 375,000 overhead LV service lines.
About 60% of the geographic area is located in Hazardous Bushfire Risk Areas (HBRA), and 40% in Low Bushfire Risk Areas (LBRA).
Most of the overhead network is located in LBRA (195,000 spans and 366,000 LV overhead service lines): with about 73,000 spans of HV overhead powerline, most of these with vegetation. Less of the overhead network is located in HBRA 19,000 spans and 9,000 LV overhead service lines) mainly on the Mornington Peninsula: with 14,000 spans of HV overhead powerline, about half of these with vegetation.
Vegetation in the vicinity of LV overhead powerlines presents a risk of electrocution and a lower risk of fire ignition (lower probability of fire ignition, with less consequence in LBRA). The greater risk is electrocution, especially to the public in LBRA.
Vegetation in the vicinity of HV overhead powerlines presents a risk of electrocution and a greater risk of fire ignition (greater probability of fire ignition, with greater consequence in HBRA). The greater risks are electrocution, especially line workers and fire ignition, especially in HBRA.
UE carries out regular audits of the status of the vegetation clearance space around the overhead powerlines managed by UE. Instances of encroachment on the vegetation clearance space, identified by UE’s audit program, are actioned by UE, or referred to the responsible persons for action, as required by the Regulations. [NOTE: In this ELCMP, responsible persons has the same meaning as the Electricity Safety Act].
The vegetation clearance space near bare overhead powerlines, in declared areas (about 90% of all overhead powerlines), is managed by the 14 municipal councils, or UE, as specified in the Regulations.
The vegetation clearance space near insulated LV service cables is generally managed by the property owner or UE, as specified in the Regulations.
In the inner suburbs (low bushfire risk, declared areas) the vegetation clearance space near bare overhead powerlines is characterised by various large species, planted on public land many years ago, and managed by councils.

11.4 Appointment of Service providers
UE has appointed three Vegetation Service Providers (VSPs) to manage its day to day inspection and cutting activities.
Select Solutions (SS) has been appointed as the vegetation service provider’s inspection (VSPI) for the entire UE network.
Active Tree Services (ATS) and Eastern Tree Services (ETS) have been engaged by UE as vegetation service providers cutting (VSPC) to ensure UE’s compliance obligations are met.
11.5 General Requirements
The VSPI will inspect the UE electricity network, record the vegetation status and notify, consult or negotiate with customers, councils, land owners, occupiers and affected persons on vegetation management issues.
The VSPC will cut or remove trees, mulch branches, remove regrowth, dispose of debris, clean-up the work site, and report the progress of works to UE on a regular basis. A limited amount of mechanical slashing of undergrowth in existing easements, stumps grinding and management of trees in other areas, may also be required.
All debris should be removed within 24 hours of completion of the work. Weather conditions and the location of debris stacking shall be considered to avoid creating a safety hazard.
In circumstances beyond the control of the VSPC, debris may remain on site for up to 3 working days provided it is located and stacked in a manner that it does not present safety or tripping hazard to the general public or livestock in all weather conditions.
Vegetation management will be carried out along established UE power line corridors. Additional vegetation clearing may also be required by, and to the satisfaction of, the relevant UE employee. All clearing activity shall comply with the requirements of the Code and the approved ELCMP.
11.6 Specific Requirements
In accordance with the ELCMP, UE requires the following work to be completed on an annual basis:
Inspect, cut and remove trees in LBRA on a 2 year cyclic program (50% of the network in LBRA, annually). In the alternate year of this 2 year cyclic program, selectively inspect, cut and remove trees in the other 50% of the LBRA network that have been previously identified as spans that have been deemed unlikely to remain compliant for the 2 year cycle (short cycle spans).
Within the HBRA this work is to be completed before, and maintained for the declared fire danger period, from the declaration date for the fire danger period or 1 December whichever occurs first.
Provide all tree related Fire Prevention Index (FPI) data and complete all works necessary to keep the FPI at zero during the declared fire danger period or post 1 December.
Identify locations where work is required to maintain the vegetation clearance space: record, maintain and upload all data to the Vegetation Management System
Manage all customer liaison activities: notification, consultation, negotiation, vegetation enquiries, work coordination and actioning all vegetation reports and issues and upload all data to the Vegetation Management System
Manage and liaise with councils, land owners, occupiers, customers on contiguous lands, and other interested parties regarding all ELC matters.
Emergency response to tree related faults from storm damage within the nominated time frame
Monthly performance reporting of Key Performance Indicators;
Feeder compliance audits

15 Management Procedures
The Vegetation Services Agreements (VSA) between UE and its three service providers specify the documented procedures that must be employed in delivering the vegetation management service.
In addition to many other requirements, the VSA stipulate that the service provider’s operations must comply with the approved Fire Prevention Plan and the approved Electric Line Clearance Management Plan (ELCMP).
The performance of each service provider is subject to routine audits and monthly reporting.
The procedures that must be employed in delivering the vegetation management service are detailed in this section.
15.1 Selection of the Method for Maintaining Clearances
The purpose of this section is to outline the strategy to be employed by UE in choosing the most appropriate method of maintaining the vegetation clearance space between powerlines and vegetation. The procedures apply to all persons associated with the vegetation management program.
In general all cutting on the UE network shall be in accordance with AS 4373, where it is as far as practicable to do so by the use of:
Suitably qualified or experienced personnel
Training and induction
Appropriate plant and equipment
Verification of cutting standards (auditing)
Actions to resolve pruning not in accordance with AS4373.
[NOTE: In this ELCMP, “practicable” and “as far as practicable” has the same meaning as the Electricity Safety Act].
In some circumstances it may not be practical to adhere to AS 4373. Cutting in these circumstances is clarified in Section 15.4.1.
The UE, Vegetation Manager is responsible for overseeing the development and implementation the vegetation management program. A comprehensive, routine, monitoring, audit, reporting and review process has been established to confirm the effectiveness of the vegetation management programs in achieving UE’s objectives.
To ensure the effectiveness of the vegetation management program, the inspection/pruning program cycles are reviewed by the vegetation manager, on each occasion that the ELCMP is reviewed, annually. The current inspection/pruning program cycles are detailed in the maintenance of vegetation clearance space section below.
The identification, evaluation and merit of alternate compliance methods are referred to the General Manager, Asset Management for assessment and implementation.
Where trees that are not the responsibility of UE have been identified as needing cutting or removal, the ORP’s are notified requesting that the tree(s) be cut or removed.
Where trees that are the responsibility of UE have been identified as needing cutting or removal, the VSPI determines the most appropriate method. Due consideration is given to the specific aspects of each site, including:
The significance of the site as a natural habitat for rare or endangered species, both flora and fauna
Areas determined by the relevant municipal council to contain culturally or environmentally significant trees, or trees specified in planning schemes to be of ecological, historical or aesthetic significance
Impact on the tree’s amenity and utility value if subjected to cutting versus removal
Assessing the benefit of implementing, available, practicable, alternative line construction methods
The reduction in risk to public safety and supply reliability
Significance and public value of the site’s aesthetics
Opportunity to replace the tree with a more suitable species over time
Environmental impact of proposed works
The information gathered during these inspections forms the basis of the SP’s plan of action and allows:
ELECTRIC LINE CLEARANCE MANAGEMENT PLAN 2017/18
Document Number: UE PL 0010
Version 5.0 – September 2017
Page 20 of 57
UNCONTROLLED WHEN PRINTED
Appropriate planning and scheduling
Adherence to AS 4373
Identification and quantification of the equipment and accredited personnel required
Required funding
Degree of community and customer consultation.
Where an area has been identified as having particular significance and has been accepted/registered by Heritage Victoria, the special conditions imposed will be recorded on the Important Tree VMS database and treated accordingly.
Alternative methods for maintaining clearances may be line relocation, offset crossarm construction, undergrounding or any other alternative compliance mechanism approved by ESV. The costs of implementing the alternative compliance method will be calculated on the basis of actual costs to be incurred, offset by an allowance for future savings associated with cutting work that will no longer be required.
A detailed inspection of each site is conducted by the VSPI to gather information to help determine the most effective method of maintaining the statutory vegetation clearance space between trees and overhead powerlines.
15.1.1 Calculating Applicable Distance (Spans <100m)
Sag and sway calculations for spans <100m are not required for graphs 1, 2, 3, and 4 as the applicable distances specified in the Electricity Safety (Electric Line Clearance) Regulations 2015, “Schedule 2” titled “Applicable distance for the middle two thirds of a span of electric line” include an allowance for sag and sway.
An additional distance, to allow for sag and sway, has been calculated for graphs 5 and 6, specified in schedule 2 of the Electricity Safety (Electric Line Clearance) Regulations 2015. The powerline graphs 5 and 6 specified in schedule 2 of the Electricity Safety (Electric Line Clearance) Regulations 2015 have been extended to allow for sag and sway, and included as Attachment B.2 of this plan.
VSPI representatives refer to the graphs contained in this plan for spans <100m, and a re-growth space is added to the AD to determine how distance required to maintain clearance throughout the two-year cycle.
15.1.2 Calculating Applicable Distance (Spans >100m)
The UE network has about 3,000 overhead powerline spans that are longer than 100 metres, many without vegetation.
An additional distance, to allow for sag and sway, has been calculated for graphs 1, 2, 3, 4, 5 and 6 specified in schedule 2 of the Electricity Safety (Electric Line Clearance) Regulations 2015 to cater for all United Energy span lengths.
These additional distances were determined using the applicable stringing charts, the span length and the conductor type.
The powerline graphs 1, 2, 3, 4, 5, and 6 specified in schedule 2 of the Electricity Safety (Electric Line Clearance) Regulations 2015 have been extended to allow for sag and sway and included as Attachment B.2 of this plan.
These graphs are used by UE and its SP’s in determining the required applicable distance.
These results will be shared with UE SPs and Councils.
15.2 Maintenance of the Vegetation Clearance Space
The purpose of this section is to outline the process to be employed by UE in maintaining the vegetation clearance space between powerlines and trees. This procedure applies to all persons associated with the vegetation management program.
In accordance with the Regulations 9(3)(i)(ii) UE has established management procedures and cutting cycles to manage trees and maintain the vegetation clearance space required by the Code. The cutting cycle frequency at each locality may be increased, by the VSPI in consultation with UE management.

15.2.1 Procedure
To determine the location where work is required to maintain the vegetation clearance space, the VSPI makes uses the following inspection programs:
Routine inspection, and vegetation cutting or removal on a 2 year cycle in LBRA and HBRA
An additional annual pre-summer inspection, and vegetation cutting or removal in HBRA
Inspection and reporting of trees in declared areas (councils), is currently carried out in conjunction with the UE cyclic program.
Additional locations where work is required to maintain the vegetation clearance space can be reports from the public, line crews and asset inspectors.
The VSPI submits regular reports to UE on the observations made during the vegetation inspection program, and UE conducts regular quality audits on the progress of the vegetation management program. The results of the vegetation inspection and removal program are recorded in the UE vegetation management system (VMS).
At each location the VSPI determines the most appropriate method of maintaining the vegetation clearance space between trees and powerlines in accordance with the procedure described above: Selection of a Method for Maintaining Clearances.
The appropriate vegetation clearance space has been established, in accordance with the Electricity Safety (Electric Line Clearance) Regulations 2015, and detailed in Attachment B.
15.2.2 Regrowth Space
The regrowth space as described in the Code is “… the smallest space such that if a tree were cut or removed from that space, the tree would not grow into the minimum vegetation clearance space around that powerline between cutting times;”.
In determining the regrowth space, the VSP considers:
The tree’s species and likely growth vigour
The current two-year cutting cycle
The prescribed vegetation clearance space
In addition to considering the health and aesthetics of the tree, when the regrowth space is calculated, every effort will be made to avoid the requirement for urgent cutting or removal work.
15.2.3 Hazard Trees
The purpose of this section is to describe how the routine inspection cycle adopted by UE includes the identification of the potential hazards associated with trees within the vicinity of UE overhead powerlines. Typically these include:
Dead or dangerous limbs
Physical defects in trees such as splitting, dry rot, root plate uplift
Trees or limbs outside the vegetation clearance space that may become unstable and fall onto the powerline under the environmental and weather conditions that could be reasonably expected in the locality
Unanticipated regrowth
Vegetation found to be inside the clearance space after declaration date.
The observations and results of routine inspections are recorded in the UE vegetation management system (VMS), and the subject of regular audit by UE’s vegetation group.
Where a potential hazard tree has been identified, either as a result of a routine inspection, a report from a customer or a field crew, a suitably qualified arborist conducts an assessment of the tree, and if the assessment confirms the likelihood of contact with an overhead powerline, considering foreseeable local conditions, the tree may need to be cut or removed.
The SP notifies the customer, or the responsible person (council), via a standard notification letter of the need to cut or remove the tree. The process including any follow up actions is recorded and monitored using the United Energy VMS.
During the routine tree cutting and removal cycle, and under emergency situations, unacceptable hazards are addressed to ensure that the vegetation clearance space remains free of foreseeable tree hazards.
The foreseeable local conditions that are considered to identify trees that could become a powerline hazard include:
ELECTRIC LINE CLEARANCE MANAGEMENT PLAN 2017/18
Document Number: UE PL 0010
Version 5.0 – September 2017
Page 22 of 57
UNCONTROLLED WHEN PRINTED
Local vegetation knowledge, especially trees that were previously shaded from prevailing winds
Soil conditions
Prevailing weather conditions, wind, rain, heat
Assessment of the land contours in the area, valleys or saddles between hills
Observations by the Country Fire Authority (CFA) in preparation for the fire danger period
Features of a tree identifiable to a qualified arborist or horticulturist.
While many trees in the vicinity of a powerline have the potential to contact conductors, it is generally not practical or environmentally acceptable to remove all of these potential hazard trees. Where a hazard tree is identified, it will be listed and monitored in the Hazard Trees Register, and actioned in accordance with the requirements of the Regulations, depending on the assessed urgency and risk.
15.2.4 Planned Cutting in the Hazardous Bushfire Risk Area
Tree inspection, cutting and removal in the HBRA is carried out under the prescribed 2 year cyclic program. Prior to the declaration of the fire danger period, UE will conduct inspections within the HBRA to ensure the cyclic program meets the objectives of the regulations in relation to powerline clearance.
The observations and results of routine inspections are recorded within the UE vegetation management system (VMS), and the subject of regular audit by UE’s vegetation group.
Removal of trees is subject to negotiation with each individual, affected party following notice in writing in accordance with this Plan.
Progress of the work is monitored against the schedule drawn up before each cutting season:
Inspect and cutting programs are planned for each area to coincide with the 14 – 60 day notification periods. When finalised these programs are loaded into the United Energy VMS, and form the “works program” for the vegetation inspectors, and cutters. Completion of the work is progressively recorded in the VMS, reviewed and reported monthly by the United Energy Service Delivery team. This reporting forms the basis of United Energy’s reporting to ESV. The KPIs and measures specified by the ESV reporting guidelines are used to monitor the progress, and completion, of the inspection and pruning programs.
15.2.5 Urgent Cutting or Removal Works
Urgent cutting or removal of trees is generally only carried out where there is an imminent risk to public safety
or the continuity of supply. This cutting or removal is at the discretion of the VSP (generally fault crews for an emergency situation or trees specialists if they are called on-site) following consideration of:
the encroachment or growth of trees that was not anticipated in the management plan
a tree falling or becoming damaged so that it is required to be cut or removed to maintain the vegetation clearance space
an arborist’s assessment under Clause 14(2) of the Code that confirms the imminent likelihood of contact with an electric line having regard to foreseeable local conditions
Observations in relation to hazard tree assessments are recorded within the UE VMS and these records are managed and are maintained within the UE VMS.
the fire danger period declared under the Country Fire Authority Act 1958.
Where urgent cutting or removal has been undertaken in accordance with Clause 13 of the Code, and as soon as practicable after completing the cutting or removal, the vegetation manager will ensure a written notice (see Attachment A.4) of the cutting and removal is provided to:
The occupier of the land where the trees were cut
The owner of the land where the trees were removed.
Details are recorded and kept for a period of no less than five years in the UE vegetation management system (VMS), and include:
Where and when the cutting was undertaken
Details of why the cutting or removal was required
The last inspection of that section of the electric line where the cutting or removal was required.
Where urgent cutting is necessary the extent of cutting is restricted to a maximum distance of one metre beyond the appropriate vegetation clearance space (including a distance allowed for regrowth, sag and sway of the conductors).

15.3 Vegetation Code Definitions and Actions
The purpose of this section is to describe the codes used by UE to document the non-compliances identified during vegetation inspection, The codes are recorded by pole number, clearly identify the non-compliant span, and assign the action period for vegetation managed by UE.
The notification, communication and recording process for the identified council and customer non-compliances shall be managed in accordance with this plan.
UE and its VSP may agree on alternative timeframes to those indicated in the tables below to cater for:
Ongoing negotiations with stakeholders (eg; :removals)
Possible engineering solutions
Access restrictions
In HBRA, during the fire season, spans requiring alternative (normally extended) timeframes must be documented by the UE Vegetation Manager together with the reasons for the alternative timeframe and any additional precautions (eg; re-assessments etc.…) that may need to be put in place to minimise risk.
This documentation is then presented to the UE Fire Prevention Committee at their next scheduled meeting for review. It is not expected any spans that have had to undergo a re-assessment under the above criteria would extend beyond 4 weeks from original overdue date.

15.4 Responsible Cutting Practices
The purpose of this section is to outline the procedure to be employed to ensure that cutting or removal of trees is undertaken in a responsible manner. This procedure applies to all persons associated with the vegetation management program.
15.4.1 Adherence to AS 4373
UE, as part of the notification and consultation with the owner/occupier, will seek to preserve the amenity value of trees, and as far as practicable, and comply with the principles of AS4373 in managing the vegetation.
In some situations it may not be practical to undertake electric line clearance cutting in accordance with AS 4373.
Such instances include, but are not limited to –
where the customer insists that work not be completed to AS 4373 (Eg; limbs not cleared to growth points)
where the amenity value of the tree is insignificant to the owner/occupier,
adherence with past practices on large windrows of Pine or Cypress hedges where the use of mechanical devices is deemed a safer and more efficient method of meeting clearance requirements with little or no negative health impacts of the tree and is not economically viable cutting AS 4373.
UE will engage suitably qualified or experienced personnel to identify and assess locations where adherence to AS 4373 is deemed to be impractical. This includes the use of the appropriate plant and equipment such as mechanical pruning, for the management of vegetation.
Where it is not practicable to comply with the principles of AS 4373 while cutting a tree in accordance with the Code, the tree cutting procedures will be subject to approval by a UE vegetation management planner.
The vegetation management planner, as part of the normal auditing regime, will also undertake audits and take corrective action, as required, where pruning is not in accordance with AS 4373.
UE will notify the owner/occupier of the extent of the proposed tree cutting to achieve code compliance, with an offer of further consultation on the planned tree cutting, as required.
15.4.2 Procedures – including Training, Qualifications and Experience
The VSP ensures that the employees and sub-contractors undertaking vegetation management activities have sufficient knowledge, their qualifications, training, and authorities are current and they have the experience, and are inducted in a manner appropriate for the task to be performed to ensure that tree management activities are conducted in a safe and environmentally responsible manner.
The VSP employees and their sub-contractors must meet the following VESI and UE training and Authorisation requirements:
VESI Skills and Training Guideline
VESI Skills and Training matrix
UE PR 0006 – Qualifications and Training Requirements for Network Access
UE PR 0001- Electrical Network access.
UE requires all vegetation personnel engaged in cutting activities to be trained in accordance with UET20312 National qualification Certificate II in ESI Powerline Vegetation Control, in line with VESI requirements.
Additional vegetation specific training requirements are provided, depending on the role of the worker. The competency units or their recognised equivalents1 are mandated for each nominated type of worker prior to undertaking the specific task such as those listed below;
Ground Crew
Tree Climbers
Cutter working from EWP
Assessor
The complete Certificate II – Units of Competence Requirements are contained on the VESI website as per the link below or any subsequent updates.

Where a person performs multiple roles they shall undertake the mandatory training for each of those roles. To operate High Risk Plant and equipment (e.g. EWP) the operator shall have the applicable High Risk Licence issued by Worksafe Victoria.
Vegetation work near a live HV line can only be carried out by qualified line workers who meet the requirements of the VESI Skills and Training Guideline, the VESI Skills and Training matrix and the Minimum Rules for carrying out High Voltage Live Work.
Records are maintained by the VSP and may be audited by UE at any time.
Prior to contract commencement, United Energy reviewed all licencing and training for all tree clearing activities.
Prior to Network Access being granted, each worker was checked to ensure that they had all of the mandatory qualifications and refresher training current.
This information is recorded and stored centrally, including a list or approved workers and their functional role.
United Energy undertakes an annual training and system audit on each contractor, where the training records of all staff are audited. Staff found on site without the relevant training are subject to the disciplinary action listed in Section 8.2 of UE PR 0006 – Qualifications and Training Requirements for Network Access
Audits are undertaken, actions created and tracked in accordance with UE PR 0007 Audit and Inspection of United Energy and Multinet Field Work Sites.
The auditors have been assigned and the audit dates planned in accordance with the UE work practices audit spread sheet.
15.4.3 Herbicide Use
UE’s use of herbicides is minimal. Any employee or service provider required to carry out herbicide work shall be trained in the use of herbicides. Any change in this practice will be subject to negotiation between the UE and the VSP and will include the use of an appropriate handling regime.
15.5 Alternative Tree Management Proposals
United Energy will consider all reasonable proposals to reduce the need for tree cutting or removal. Written proposals will be forwarded to the General Manager Asset Management for consideration, accompanied by all of the information required to consider the proposal.
The General Manager Asset Management will contact the applicant within five working days and explain the process for handling the proposal, and outline any costs that may be involved in assessing the proposal.
Where the applicant wants to continue with the proposal, the General Manager Asset Management will provide the applicant with indicative costs of the proposal within 30 days. These costs will consider benefits that UE may receive from the proposal, such as reduced vegetation management costs.
15.5.1 Alternate Compliance mechanisms
The Electrical Safety (Electric Line Clearance) Regulations 2015 provide for alternative compliance mechanisms. UE is committed to working with stakeholders to ensure the safe, efficient supply and use of electricity.
Before any alternative compliance mechanism can be considered for use on the electricity network, it must be accompanied by a formal safety assessment and meet the requirements of United Energy’s product approval process.
The proposal must be supported by Manufacturer’s details:
Manufacturer’s name, type and model number of the product
Manufacturer’s certified recommendation supporting the intended use of the product
Recognised international standard(s) that apply to the product, design, manufacture, testing
Source of materials and place of manufacture

The proposal must be supported by an engineering assessment, completed by a recognised subject matter expert, on the impact on the alternative compliance mechanism:
de-rating effect on the powerline
effect of the additional loading on the powerline
changes to existing work practices
method for inspecting the alternative compliance mechanism
cost/benefit analysis for the alternative compliance mechanism.
Currently UE does not have any alternate compliance measures in place and have not received any proposals for alternate compliance measures.
15.5.2 Long Term Strategies
In addition to implementing this Plan, to avoid trees growing into, or encroaching on the vegetation clearance space as UE has implemented a number of other strategies to minimise the risk posed by trees to the safe operation of powerlines including:
Installation of insulated (ABC) conductor and undergrounding sections of powerline subject to UE business rules
Deployment of various electrical protection devices both within substation yards and at strategic points throughout the network.
15.6 Important Trees
This section outlines the procedure employed to ensure important trees are identified and documented in the VMS, and given special consideration when and cutting or removal is proposed. This procedure applies to all persons associated with the vegetation management program.
The Important Trees are recorded electronically in the VMS against the span or as a specific tree/s. The data can accessed by running the special requirements filter in the VMS.

UNCONTROLLED WHEN PRINTED
UE recognises that there are some trees in the service territory that are of special importance due to their:
Species (Native/Exotic)
Ecology (identified in Planning Schemes)
History (identified in Planning Schemes)
Aesthetics (identified in Planning Schemes)
Culture (identified in Planning Schemes/Heritage Registers)
Environment (identified in Planning Schemes/Heritage Registers)
Habitat - invertebrate/vertebrate fauna (Listed as threatened in accordance with section 10 — Flora and Fauna and Guarantee Act 1988).
The VSPI will consult with stakeholders to ensure that where practicable, these trees and sites are given special consideration in planning tree cutting or removal activities, in a safe manner.
Procedure
The VSPI shall make every effort to determine the location of important trees by consulting:
State and local government records
Planning schemes and overlays
Community groups
Land owners/occupiers.
The VSPI, on behalf of UE, monitors the data contained in the Department of Environment, Land, Water and
Planning (DELWP) Threatened Invertebrate/ Vertebrate Fauna listings, at least annually.
Under section 11 of the code a responsible person must not cut or remove a tree that is habitat to threatened fauna during the breeding season for the threatened fauna unless;
(a) it is necessary to cut or remove the tree for safety reasons, or
(b) it is not practicable to undertake cutting or removal of that tree outside the breeding season
Notwithstanding these situations the cutting or removal of trees with threatened fauna is generally planned to be undertaken outside the breeding season for the species wherever practicable.
If this is not practicable the Vegetation Manager, in conjunction with the VSPI, will engage a suitably qualified, professional in the field of local fauna identification on the appropriate course of action to translocate the fauna.
UE and the VSP use the VMS to record spans where important trees have been identified, and this database is consulted when vegetation management or network augmentation work is planned.
The VSPI delivery manager consults, and negotiates with the persons responsible for important trees prior to the commencement of any work to determine the most effective way of protecting the affected trees and restricting the cutting or removal of native trees, cultural or environmentally significant trees to the minimum extent necessary to achieve the required vegetation clearance space.
Reports are provided to UE on the process and outcomes of discussions, which are subject to regular audit by the UE vegetation group.

Actions considered by UE and the VSP to mitigate the impact may include:
More frequent cutting of the vegetation (facilitated by UE and funded by stakeholder)
CAPEX solution (facilitated by UE and funded by stakeholder).
Using these strategies will initiate greater interaction between UE, councils and other stakeholders in deciding the most appropriate methodology for maintaining vegetation clearance.
15.6.1 Species Identification
For the purposes of this plan “native trees” are defined as “trees that are indigenous to a specific area and are regarded as significant by a local government, the community or customers”
As required by regulation 9(3)(h), the locations of native trees where identified are included within the important tree register.
Additional information sources used to identify the location of important trees are listed below
15.6.2 Trees of Significance Listed in a Planning Scheme
Some municipalities have developed a listing of significant trees within their region. The VSPI (as required in regulation 9(3)(g) (ii) liaises with these municipalities to identify the trees contained within Planning Schemes that are deemed to be of ecological, historical or aesthetic significance and add them to the important tree VMS database as required.
A total of 14 Municipal Councils serve the rate payers supplied by the UE electricity distribution network. UE works closely with each of these Councils to address electricity supply and vegetation management issues to facilitate compliance with the various Acts and Regulations.
Councils Located within the UE Franchise Area
Bayside Boroondara Casey Frankston Glen Eira Dandenong Kingston
Knox Manningham Monash Mornington Port Phillip Stonnington Whitehorse
As part of the regular dialogue with councils, trees of significance, of cultural or environmental significance or
habitat trees for threatened fauna will be addressed and tree registers updated.
15.6.3 Trees that are Culturally or Environmentally Significant
UE has researched and compiled a list of trees deemed to be culturally or environmentally significant (as required in regulation 9(3)(g)(iii)). For trees of cultural or environmental significance the following resources were used:
15.6.4 Victorian Heritage Register.
The Victoria Heritage Register (VHR) is available on the Department of Transport, Planning and Local Infrastructure web site.
http://vhd.heritagecouncil.vic.gov.au/search?cat%5B0%5D=2&do=s&collapse=true&type=place&spage=1&tab=places&view=detailed&rpp=25&cp=16
The VSPI is required to check each of the records in detail and update the VMS with the relevant information required by the vegetation assessor to identify any trees on the Heritage List that may be within the UE area. The VSPI also checks the VHR for variations at least once a year.
15.6.5 Victoria Aboriginal Heritage Register.
The Victoria Aboriginal Heritage Register is available on the Department of Premier and Cabinet web site. This register is available on a need-to-know basis, due to the culturally sensitive information. The VSP either maintains an authorisation to access the register, or makes an annual application to Aboriginal Affairs Victoria to obtain a report covering the UE geographic area. The VSPI notes variations in the report from time to time.
15.6.6 Habitat Trees for Threatened Fauna
There are no specific listings of habitat trees with a conservation status of “vulnerable”, “endangered” or “critical endangered” fauna currently available in Victoria. The information sources referenced by the VSPI to try to identify these locations are:
- Flora or a Habitat of Fauna
The VSPI checks the Department of Environment and Primary Industries (DEPI) “Flora and Fauna Guarantee Threatened List” at least once every year for variations. The list is specifically referenced in section 10 of the Flora and Fauna Guarantee Act 1988 and rarely changes.

16 Notification, Consultation and Negotiation
Procedure
This section outlines the procedure to be employed by the VSPI to notify, consult and negotiate with the:
owner (removal) or occupier (cutting) of the land where the cutting or removal is to take place,
local council, where the council is the owner of the tree but not the responsible person
the occupier of land contiguous where the use of that property may be affected from the tree cutting or removal activities. (eg; road or driveway blocked by EWP’s etc…..)
as prescribed under Schedule 1, Division 3, regulation 15 of the regulations.
This procedure applies to all persons associated with the UE vegetation management program and includes the type of notices that are required to be issued by the VSP as part of the work assessment.
Any urgent cutting or removal shall be carried out in accordance with this plan.
16.1 Notification for Cutting or Removal
The UE, Vegetation Manager is responsible for developing and managing the vegetation management program.
The VSPI will initially notify all persons in writing, in accordance with the requirements of the Electricity Safety (Electric Line Clearance) Regulations 2015, with a minimum 14 days’ notice and not more than 60 days’ notice before the intended cutting or removal is to occur.
Re-notification required as a result of notification falling outside 60 day notified timeframe, or if changed cutting practices are required to meet code requirements is usually carried out by the VSPC.
Regular audits are completed by UE to confirm that notifications have been distributed, within the 14-60 day notification period, and distributed to the right category of person. Where pruning cannot be completed within the 14-60 day period, the notification process is repeated.
The notice shall convey the following essential information:
An explanation of why compliance with the Code is essential
Why the proposed works are necessary
The tree cutting work that will be carried out and who will carry out the work
An invitation for further consultation or additional detail about the tree cutting work prior to work commencing
Name and telephone number of contact person for further consultation, additional detail, or any matters of concern
Dispute Resolution Procedure
An indication that the tree cutting works is generally the same as performed previously
Information on tree/s of cultural or environmental significance, details of the impact of the cutting or removal of the tree, and the actions to be taken to minimise that impact.
Samples of typical notification letters are in attachments in this plan as per below; o A.1. General Cutting or Removal o A.2 Change from Previous Cutting Practices or Methods o A.3 Contiguous Land o A.4 Urgent Cutting or Removal has been undertaken

o A.5 Trees of Importance, Cultural or Environmental Significance o A.6 Service Lines
16.1.1 Published Notices
Under “Division3”, “Section 16 (3)” of Schedule 1 of the Code of Practice a when cutting or removal a tree on public land “written notice must be published under subclause (2) must be published in a newspaper circulating generally in the locality of the land in which the tree needs to be cut or removed”.
These methods of notification would include the following circumstances where the trees are deemed UE’s responsibility;
trees located on the road reserve or nature strip in undeclared (normally rural) areas, and;
trees located on public lands (Vic Roads/Water Authorities etc…) in declared (normally urban) areas other than those managed by councils
In accordance with ESV correspondence 27 November 2015, “Electricity Safety (Electric Line Clearance) Regulations 2015 – Guidance Information” which states:
United Energy shall adopt one of two methods.
1) The VSPI will provide written notification (as per Attachment A.1. Customer Notification Letter) to any residents within the vicinity of such works stating that the work will only commence between 14 and 60 days from the date of this notice; or.
2) The VSPI will place a notice in the newspaper (as per below), to make stakeholders aware of the planned cutting or removal of tree(s) on public land and stating that the work will only commence between 14 and 60 days from the date of this notice.
16.1.2 Consultation for Cutting or Removal
If the tree intended to be cut or removed is within the boundary of a private property, the VSPI will consult with the owner or occupier.
NOTICE OF VEGETATION PRUNING OR CLEARING NEAR POWERLINES
United Energy (UE) owns and maintains the poles and wires in the south eastern suburbs of Melbourne and the Mornington Peninsula. UE has a vegetation management program, which includes regular inspections by our service providers of powerlines and tree proximity to maintain an uninterrupted fire safe supply of electricity.
We recently conducted a powerline inspection that identified vegetation on public land and/or within the boundaries of private properties that requires clearing. These works are scheduled to occur in the following suburbs; Arthurs Seat, Baxter, Carnegie, Carrum Downs, Dandenong South, Dromana, Flinders, Heatherton, Hughesdale, Main Ridge, Malvern East, Merricks, Merricks Beach, Merricks North, Moorabbin, Mornington, Mount Martha, Mulgrave, Point Leo, Red Hill, Red Hill South, Safety Beach, Shoreham, Surrey Hills, Tuerong, Clayton, Dandenong North, Glen Waverley, Knoxfield, Langwarrin, Mount Waverley, Mulgrave, Noble Park North, Notting Hill, Oakleigh East, Rowville, Scoresby, Templestowe, Wantirna South And Wheelers Hill over the next 60 days in order to maintain the required clearance space around power lines. Individual properties with vegetation requiring clearing will have received notification by letter drop, 14 days prior to commencement of clearing.
Should you require further consultation or details regarding proposed pruning or clearing, please contact our Customer Service Centre on 1300 792 456 (8am to 5pm Mon to Fri).

As part of the UE written notification process, the owner or occupier will be invited to contact the nominated UE representative on the phone number provided, if required, for consultation, additional information, or to address matters of concern about the tree cutting work prior to the work commencing.
It not always possible for UE to identify or contact the property owner or occupier. Name and contact details may be unknown or subject to a confidentiality arrangement. The most practical approach is for UE to invite (encourage) the owner or occupier of the property to contact UE, and discuss any issues or concerns that they may have as part of the notification process.
Where a change to previous cutting practices or methods for the removal of trees near powerlines is being implemented UE will encourage direct consultation owner, occupier and local councils. A change from previous cutting practices or methods may be cutting further than previously, more canopy reduction or tree cutting using mechanical methods. Notice (see attachment A.2) encourages owner or occupier and local councils to contact the VSPI.
The following flowchart illustrates how the negotiation and consultation process is utilised by the VSPI to manage any customer interactions
16.1.3 Negotiation Process
The VSPI must decide on how to maintain the required clearance between powerlines and trees so that the vegetation clearance space remains free of vegetation in accordance with the section “Selection of a Method of Maintaining Clearances”. However, this does not preclude affected persons from negotiating conditions under which other solutions may be used in accordance with the section “Alternative Vegetation Management Proposals”.
As part of the negotiation process where agreement on the cutting or removal of vegetation cannot be achieved, the VSPI will advise the affected person of the UE dispute resolution procedure, and the process to be employed to negotiate alternative powerline clearance arrangements that may avoid or reduce the need for tree cutting or removal, together with any conditions that may apply to such arrangements.
The VSPI will maintain a detailed record of the negotiation process.

Where a dispute arises during the negotiation process, between the property occupier, owner or council and the VSPI regarding the proposed cutting, removal or alternative arrangements, it shall be resolved in accordance with the UE Dispute Resolution Procedure.
Notwithstanding the nature of the dispute and the need to resolve the dispute in accordance with the UE procedure, the duty of UE to maintain the vegetation clearance space at all times shall not be compromised.
Where landowners or occupiers refuse to allow UE representatives access or permission to maintain regulatory compliance ESV will be notified of such situations for assistance. As a result ESV may issue the landowner or occupier a letter to the customer in support of UE endeavours to achieve compliance and with an example of such a letter provided in Attachment A.9 of this plan.
16.1.4 Dispute Resolution Procedure
The UE Dispute Resolution Procedure, based on attempting to resolve complaints at the earliest, lowest possible level, shall be explained all stakeholders involved. Where the dispute cannot be resolved at the lowest possible level, the process allows for escalation of the dispute to the next level of management.
The various dispute escalation levels are shown below, together with more detail on the process at each level of escalation:
1. VSPI Assessor 2. VSPI Inspections Program Leader and/or Cutting Program Leader 3. UE Vegetation Planner/Auditor 4. UE Vegetation Manager 5. Customer Operations 6. Energy and Water Ombudsman (Vic) (EWOV).

17 Monitoring, Reporting and Auditing
UE has developed a Vegetation Management System (VMS) which includes a set of reportable items to monitor the performance of the vegetation management program. Key items are monitored and reported by the UE Vegetation Management team on a monthly basis as part of the normal monthly reporting regime.
As a minimum the reportable items, will be the Key Performance Indicators specified in section 4 of Energy Safe Victoria “Electrical Infrastructure Safety Electrical Incident and Safety Performance Reporting Guidelines”.
ELECTRIC LINE CLEARANCE MANAGEMENT PLAN 2017/18
Document Number: UE PL 0010
Version 5.0 – September 2017
Page 36 of 57
UNCONTROLLED WHEN PRINTED
UE uses a number of measures to assess the performance of the VSP. The KPI’s are outlined in the “Vegetation Cutting/Inspection Service Agreements” and monitored on a monthly basis. An example of the VSPC KPI is outlined below.
17.1 Auditing
17.1.1 Audit Roles and Responsibilities
The accountability for auditing the performance of this Plan, the vegetation components of the UE fire prevention plan and the vegetation service agreements currently within place with the VSP including key performance indicators (KPI) rests primarily with the UE Vegetation Manager.
The UE health, safety and environment manager also undertakes scheduled audits on compliance with OH&S requirements.
Responsibility for these audits is delegated to the UE vegetation planner/auditors and/or health and safety auditors who complete scheduled field and desktop audits of the VSP to ensure that performance complies with the requirements.
Components of these audits include but not be limited to;
Compliance with Code
Quality, including pruning in accordance with the principles of AS 4373
Customer feedback, complaints, and satisfaction
Worksite Management (OH&S)
Qualifications and Competency
17.1.2 Schedule and Frequency
United Energy inspects about 110,000 spans of overhead powerline each year, and about 10,000 spans of overhead powerline in HBRA before summer each year.
ELECTRIC LINE CLEARANCE MANAGEMENT PLAN 2017/18
Document Number: UE PL 0010
Version 5.0 – September 2017
Page 37 of 57
UNCONTROLLED WHEN PRINTED
For a population of 110,000 spans, the statistically significant audit sample size, for a 95% confidence level is about 400 spans (using the Raosoft sample size calculator available on the internet).
The UE audit sample size for vegetation management activities, exceeds 400 spans per annum.
To cater for variations in the size of vegetation management activities (sample size), and simplify the audit process, as shown in the table below, United Energy has increased the audit sample size as shown in the table below.
The annual vegetation management audit program is determined by the UE vegetation manager and carried out in accordance with the “United Energy Vegetation Auditing Process” (see table of contents below).
The scope of the audit will be governed by the scope of the inspection and cutting work. Hedge rows will be treated differently to a large overhanging trees, differently to a prized private tree, and differently to an entire feeder. HBRAs will be treated differently to LBRAs. The frequency of the audit will be governed by the scope of inspection and cutting work and the rate of completion of the inspection and cutting program.
Additional audits are also to be completed at a number of levels by:
VSP,
UE Vegetation group,
UE Health and Safety group,
UE Electricity Networks team, and
ESV.
17.1.3 Recording and Managing Results
Vegetation audit results including any actions are recorded and tracked within UE’s VMS and reported as required to the;
Service Delivery Management Team
UE ESMS operations and steering committee,
Fire prevention committee
Audit and Risk committee
ELECTRIC LINE CLEARANCE MANAGEMENT PLAN 2017/18
Document Number: UE PL 0010

Page 38 of 57
UNCONTROLLED WHEN PRINTED
The Network Risk, Safety and Technical Compliance Manager is responsible for analysing and reporting the correlation between the audit results and UE’s KPIs, following up and tracking progress on actions arising from the audit observations.
17.1.4 Summer Inspection Programs in HBRA
Within the UE HBRA a summer inspection and pruning program will be conducted annually on all or part of UE’s approximately 19,000 spans.
The vegetation manager will ensure that the VSP complete their HBRA programs by late November or earlier if and an early declaration date is anticipated.
17.1.5 Compliance with the Code
The 2 year cyclic vegetation inspection and pruning program monitors and reports on the location and status of vegetation near powerlines and records all information associated with such vegetation into the VMS.
Information from the VMS will be used to report on UE’s compliance with the regulations. A copy of the reports will be shared with ESV, monthly. The historical work programs and the program completion data will be used to test, challenge and confirm United Energy’s compliance with the regulations, as well as identify areas where remedial action may be necessary to improve deficiencies in the program, and improve performance.
The methodology utilised to confirm ongoing compliance with the code is to monitor the number of spans that remain outside of the clearance space for the duration of the vegetation clearing cyclic. Currently UE measures the level of compliance using historical data within the HBRA only, using the Summer Audit Program data.
It is UE’s intention to measure this compliance across its entire network by utilising the historical data contained within the VMS upon completion of the second vegetation clearing cycle in 2018/19.
17.1.6 Exception to minimum clearance space
Currently UE does not utilise the exception to minimum clearance space clauses within the code.
18 Assistance to Councils and Land Owners/Occupiers
UE will communicate regularly with all Councils within its territory, and liaise more closely with councils that have had difficulty in achieving compliance with the Regulations. UE will contact councils at management level to help these councils achieve compliance by raising the profile of vegetation compliance to management level and highlight the risk exposure and regulatory penalties.
UE will work closely with ESV to help councils become more compliant with the Electricity Safety (Electric Line Clearance) Regulations 2015 and address emerging issues in a timely manner.
Where non-compliant trees are identified that are a threat to the integrity of the network, and are the responsibility of an ORP or council, the VSPI will notify the ORP or council of the areas requiring attention and request the ORP or council to report the progress of vegetation clearing work, in a timely manner.
UE will also provide assistance to councils in relation to sag and sway data for all spans, as required.
UE plans to meet with councils on a regular basis. One meeting will be held with councils with HBRA in August to discuss summer preparedness programs. The timing of other council meetings may vary depending on the vegetation management issues.

18.1 Interaction with Council and Land Owners/Occupiers
UE shall inspect its overhead assets and Private Overhead Electric Lines (POEL) in accordance with the Regulations and the procedures set out in this Plan.
Councils and land owners/occupiers shall be notified of their obligation, as the Responsible Person, to clear trees that are infringing on the vegetation clearance space. Follow up audits will be conducted on councils and POEL landowner/Occupiers where appropriate to ensure that action has been taken in accordance with the Code.
Upon request, the VSPI will assist councils and land owners/occupiers to safely cut or remove trees near powerlines by providing advice on:
safe work practices including safe limits of approach
the de-energising of lines
the suppression of the auto re-closing feature on HV feeders
authorised local service providers
location of HV feeders.
The VSPI will provide information to councils, land owners, occupiers and the public on the appropriate planting and maintenance of trees near powerlines. The information provided may include a copy of the brochure reproduced in the Attachments.
Each year, UE shall advise owners of POEL of their responsibilities in relation to these powerlines. In accordance with the Private Overhead Electric Lines Procedure, brochure FPP25 in the current UE Fire Prevention Plan (reproduced in the Attachments) is included in the mail-out to these customers.
UE shall notify councils, land owners, and occupiers, as Responsible Persons, of any vegetation not meeting the clearance requirements outlined in the Regulations. Where the councils, land owners, or occupiers refuse or are unable to clear the vegetation within a reasonable timeframe UE may liaise with ESV regarding any further action to be taken. See the flow chart below.
18.1.1 Declared Area Hazard Tree Rectification Process
As part of the UE vegetation inspection program, councils will be notified of trees that infringe into the vegetation clearance space and threaten the integrity of the powerline, that are the council’s responsibility. Councils will be requested to provide the required vegetation clearance space at each location within 14 days.
In the interest of public safety and supply integrity, follow up audits will be conducted to ensure that the appropriate action has been taken to achieve compliance with the Code.
Where trees have not been cut or removed to achieve compliance with the Code within the agreed period, council will be reminded of the requirements of clause 86(5) of the Electricity Safety Act 1998 and UE’s process for the management of vegetation that is council responsibility.
18.1.2 Non Compliance by Councils or Other Responsible Persons (ORP)
If there is no feedback/action in relation to the initial notification, UE (or their agent) may issue a formal “notice of failure to maintain lines” to councils or an ORP or subject to section 86(1) of the Electricity Safety Act 1998.
If there is no feedback or action in relation to the formal notice, UE (or their agent) may refer these trees to ESV requesting their agreement (via certificate) for UE (or their agent) to “… carry out the duties and perform any work necessary to ensure that the whole or any part of a tree is kept clear of the line” (refer Electricity Safety Act 1998, section 86(5)).
Where ESV or UE considers the line to be in such a dangerous condition that urgent compliance with the notice is necessary within 14 days from the date of the notice (refer Electricity Safety Act 1998, Section 86(4)) or where there is an imminent risk to public safety or the continuity of supply, cutting or removal shall be undertaken in accordance with Regulations.
UE “may recover the costs of carrying out any work… from the responsible person to cut or remove these trees (refer Electricity Safety Act 1998, Section 86(7)).

Dear Customer,
ATTENTION: URGENT CUTTING OR REMOVAL OF TREES
Urgent cutting or removal of trees is generally only carried out where there is an imminent risk to public safety or the continuity of supply.
In accordance with Clause 18 of the Code of Practice for Electric Line Clearance, UE has a process to notify landowner/occupiers, as soon as practicable after completing the cutting or removal where urgent cutting or removal has had to be undertaken.
Where urgent cutting is necessary the extent of cutting is restricted to a maximum distance of one metre beyond the appropriate vegetation clearance space (including a distance allowed for regrowth, sag and sway of the conductors).
The reason urgent cutting or removal was carried out at your premises was as follows:
Tree or branch unanticipated growth had to be cut away from the vicinity or directly from the powerlines
Tree or Branch had failed, become unstable or declared as posing an imminent danger to the powerlines
The tree that required urgent pruning was last inspected as per below:
The tree was last inspected by UE on the XX/XX/XXXX

RE: CLEARANCE OF TREES FROM OVERHEAD ELECTRIC LINES
Under the Electricity Safety Act 1998 and the Electricity Safety (Electric Line Clearance) Regulations 2015, United Energy is required to undertake electric line clearance activities in accordance with the approved electric line clearance management plan.
The purpose of the electric line clearance activities is to prevent vegetation growing too close to electric lines and increasing the risk of electrocution, starting fires or power outages.
The Electricity Safety Act 1998 defines the powers that enable United Energy to fulfil these responsibilities. This includes the power to enter onto and remain on any land, for as long as necessary to complete the work required.
United Energy has identified that urgent works are required on the power line at <<address>>.
Your cooperation in facilitating access to this power line is encouraged as preventing this work will increase the risk of electrocution, starting fires and the power outages.
Should you have any enquiries regarding this matter please contact the designated United Energy representative on xxxx xxxx or at [email protected].
Yours sincerely <<name>> <<title>>
