1 Introduction

MVV Environment Devonport Limited (MVV) has been awarded the South West Devon Waste

Partnerships (SWDWP) residual waste treatment and disposal contract. The SWDWP is a

collaboration between Plymouth City Council, Torbay Council and Devon County Council

which is to provide a long term solution to manage waste from the southwest Devon area,

which is not re-used, recycled or composted.

MVV's proposal is to construct and operate an Energy from Waste (EfW) facility, incorporating

Combined Heat and Power (CHP) technology, on land currently situated in the north east of

Her Majesty's Naval Base (HMNB) Devonport, Plymouth.

This Construction Environmental Management Plan (CEMP) is for the construction phase of

the development, and sets out the intended methods of effectively managing potential

environmental impacts arising from the construction of the EfW CHP facility.

The responsibility for implementation of the CEMP lies with the Principal Contractor MVV O&M

GmbH and it shall be implemented and controlled by the Site Manager who shall work in

conjunction with key personnel (Construction Director, contractors, suppliers, etc.) to ensure it

is implemented. In order to ensure that the plan remains relevant it will be the responsibility of

the Site Manager to take ownership of the CEMP and ensure its relevance to activities being

undertaken on site in light of any changes from the initial scope of the plan, this requires its

regular revision and updating as necessary. Any revisions or updates shall be subject to

agreement in writing with the LPA.

2 CEMP Overview

This CEMP identifies the project management structure roles and responsibilities with regard

to managing and reporting on the environmental impact of the construction phase. An

Environmental Impact Assessment (EIA) was undertaken during the planning process which

identified and assessed the aspects of construction that could have an environmental impact.

All proposed mitigation measures described in the EIA will be applied and are specifically

described in the applicable sections of the CEMP.


The overall environmental objectives that will be applied to the project are:

All practicable steps shall be taken to minimise the environmental effects of construction works.

All activities shall be conducted in accordance with the CEMP, relevant legislation, Codes of Practices, Guidelines, and any local environmental procedures.

Environmental licenses, permits and consents and other statutory requirements are to be obtained prior to works commencing, and fully complied with.

All staff (including sub-contractors) shall be aware of the environmental issues relevant to the Project through the provision of site specific information on the

environmental impacts of construction and the mitigation measures to be applied

during inductions, briefings and tool box talks and other relevant .

Regularly reviewing of the environmental requirements of the project and ensuring that environmental controls remain adequate throughout the duration of the project.

3 Roles and Responsibilities

Briefings and Toolbox Talks covering topics relating to specific site activities. These shall be

given to all site personnel at a period of no less than fortnightly.


Environmental Bulletins and Newsflashes shall be clearly displayed in all mess / office areas.

Any actions relating to these shall be implemented immediately, and all site personnel made

fully aware of any changes.

4 Environmental Management

The site shall implement a project specific Environmental Management System (EMS)

complying with BS EN ISO 14001. The EMS shall be monitored and audited by appropriate

personnel throughout the duration of the works. An audit schedule shall be created which

includes both internal and external EMS and legal compliance audits. Any system failures

shall be documented and appropriate corrective actions issued and implemented.

An environmental impact assessment has been undertaken for the project during the planning

process. All identified risks are addressed within this document. However, should any

additional risks be identified, other than those outlined in this report, supplementary

management plans shall be put into place.

The construction of the facility is anticipated to take approximately 30 months and will involve

a phased construction programme involving a number of main construction activities. A set of

phasing diagrams are included in attachment 12 which illustrate the sequence of construction

and the areas of the site in which work will be carried out during the various main construction

phases .

Pre-Phase/Activity planning

During the initial planning of each phase of construction and prior to the commencement of the

relevant phase the activities likely to cause environmental impacts will be identified and the

most suitable mitigation measures selected from those identified generally in this CEMP for

the specific activities will be incorporated within the relevant phase activity method statement .

These mitigation activities will be communicated to and agreed with the LPA no later than 2

weeks prior to the start of the relevant phase of the construction.

The following subsections outline the processes and methods to be implemented on site to

ensure all environmental risks are identified and sufficient mitigation measures are put in place

to reduce environmental impacts associated with the works.


4.1 Overall Project Management Actions

All environmental documentation shall be kept on site at all times and be available for

inspection by internal and external auditors and regulators, as well as the client and

management. Site personnel shall be made aware immediately if any significant changes in

work procedures are implemented.

Relevant documentation shall include the following:

Site Weekly Checklist Impacts and Aspects Matrix Environmental Risk Assessment Construction Environmental Management Plan Site Waste Management Plan Pollution Prevention Plan including emergency response Training and Responsibilities Matrix

Weekly environmental inspections shall take place on site by the construction supervisor. The

findings of these inspections and any associated actions shall be appropriately documented

on the Weekly Checklist.

Site management shall meet as necessary with the LPA to review activities on site and the

potential environmental impacts and mitigation measures relevant to those activities that will

be implemented.

MVV O&Ms site management shall regularly liaise with the Environment Agency and other

authorities and regulatory bodies with regards to all consents, exemptions and licences. Any

applications shall be made with consideration of appropriate timescales.

A consents schedule shall be completed and held on site files, detailing information from date

of application. Where specific limitations are set through any licence, consent or exemption,

this is to be clearly identified and regularly reviewed to ensure compliance.

The Site Emergency Response shall be found within the Pollution Prevention Plan. Contact

details shall be clearly displayed on site and information explained to all site personnel. The

Pollution Prevention Plan shall contain a clear detailed plan of the site which indicates the

location of sensitive receptors such as watercourses and drainage points. An appropriate

number of spill kits shall be located within these areas and will be clearly marked on the plan.


It is the responsibility of the site management to ensure all spill kits are fully stocked at all

times, and an inventory of equipment within the spill kit is to be clearly displayed within.

The project is registered with the Considerate Constructors Scheme (CCS) under registration

number: 19164.

The CCS is a non-profit-making, independent organisation founded by the construction

industry to improve its image. The CCS is neither grant maintained, nor funded by the

government, and is solely financed by its registrations. The CCS Codes of Considerate

Practice commit those sites and companies registered with the Scheme to be considerate and

good neighbours, as well as respectful, environmentally conscious, responsible and

accountable. Registered sites and companies must also consider their appearance and safety.

This commitment is maintained by the CCS monitoring registered sites and by the display of

posters around the construction site, setting out the Code to which the sites or companies are

committed. If passers-by wish to comment, the name and telephone number of the site

manager or company contact are clearly displayed, alongside the freephone telephone

number of the CCSs administration office.

CCS Monitors who are drawn from the senior ranks of all disciplines within the construction

industry, with a fairly even division between architects, engineers, contractors and surveyors,

visit the site on a regular basis. The Monitor acts as an 'informed member of the public' and is

looking at how the site represents the company and the industry. During the visit, the Monitor

will assess the perimeter of the site, the access to the site offices and the facilities provided for

the operatives. The Monitor will also review whether the site's procedures are in accordance

with the Scheme's Site Code of Considerate Practice.

The Monitor will write a report for the Site Manager and this will include the score achieved

against each of the eight categories of the Scheme's Site Code of Considerate Practice. The

purpose of this score is to indicate how well the site is performing against the Code.

The site shall comply with the CCS Site Code of Considerate Practice and target to maintain a

score of no less than 33 on each site monitor's visit. The site shall clearly display the

associated posters and banners allowing local residents to see clearly all contact numbers.

MVV shall ensure all works carried out are undertaken in a manner which not only ensures

best practice, but ensures minimal disruption and cause for complaint by the public.


Training and management procedures

To ensure that mitigation methods and measures are applied, appropriate training and

management procedures will be implemented in accordance with Building Research

Establishments (BRE): The Pollution control Guide: Part 1 Pre-project planning and

effective management.

The BRE guidance makes the following recommendations: Before the start of any project,

appropriate training on how to control pollution emissions should be given to all personnel

expected to be present on site. This training should include;

The benefits of reducing pollution to health and environment, The benefits of minimising disruption from complaints and enforcement actions, Methods to minimise the generation of pollution, Actions plans on what should be done if emissions breach any limits that have

been set for the particular site,

Individual responsibilities and management procedures, The importance of effective communication between relevant personnel at all

levels.

All site personnel, site operatives and sub-contractors will be made aware of the risks and

mitigation methodology for any potential environmental impacts relevant to their specific

activities through the Site Induction and regular briefings and toolbox talks.

Consultation with the public

In conjunction with appropriate mitigation, operating hours and employee training, handling

public relations in an appropriate way will help to reduce the potential for air quality

complaints. BRE: The Pollution control Guide: Part 1 Pre-project planning and effective

management makes recommendations regarding the handling of public relations. These

recommendations will be implemented at the site;

Notice boards on the site perimeter fencing will display telephone and email contacts for

enquiries and receipt of complaints, and the name of the persons who should be contacted


4.2 Dust

The site is located within the Weston Mill area of HM Naval Base Devonport. The Naval base

borders the majority of the site with the exception of the northern boundary. The boundary to

the site has a range of residential properties which are noted as sensitive receptors. The

potential receptors were identified in the EIA and these are shown in Attachment 10.

Other ecologically sensitive receptors are noted as being;

Tamar Estuary Blackies Wood Weston Mill Stream Weston Mill Lake Barne Brake Camels Heal Creek Groundwater

It is also recognised that in periods of high winds the receptors affected by wind blown dust

could be areas further away than those mentioned above if suitable dust mitigation measures

are not implemented.

The generation of dust outside of the site boundary is a potential source of statutory nuisance

and can lead to complaints being received. As well as receiving complaints dust can also have

an impact on human health and local ecology. The Environmental statement outlined the

residential properties within 100m of the main construction area who may experience

occasional increase in local soiling during activities being carried out in extremely dry and

windy weather. These are deemed to be short-term episodes with a likely result in increased

soiling of property surfaces, and are not normally associated with the general risk to health.

Whilst this statement outlines the potential impact from dust on residents the mitigation

outlined in this section will focus on removing the potential from nuisance dust emissions.

It should also be noted that the naval base and its operations are also a consideration during

the project phases.

Potential dust sources during the construction phases of the development works:

Site clearance Ground excavation, piling and earthworks


On site earth moving operations, site levelling, cut and fill etc. Vehicle movements over haul roads (especially unpaved) Vehicle movements on site during dry periods Re-suspension of particulates from construction vehicle movements on site, Wind blowing across the site during dry periods Stockpiling of excavated materials Cutting, grinding and drilling operations Accidental spillage and loss of load from vehicles carrying loose material Deep excavations Tipping Earthworks

The generation of dust nuisance requires consideration of additional factors such as:

Prevailing wind (speed, direction) Prevailing climate, including rainfall Location of sensitive receptors (including residential and commercial properties,

habitats and watercourses)

Potential impacts

Background information

The Environmental Protection Act lists the emission of dust from industrial, trade or business

premises in sufficient quantity to be prejudicial to health or a nuisance as a statutory nuisance.

Dust which is raised by site operations may be carried to nearby residential areas and if

present in sufficient quantities has the potential to cause a nuisance by settling on clean

surfaces.

There are no UK statutory or recommended levels of dust deposition that constitute a statutory

nuisance; whether or not a nuisance exists is determined in the first instance by the

professional judgement of the environmental health officer.

Dust contains particles in the range of sizes. The finer fraction of dust particle range is more

likely to become airborne and to travel beyond the boundary of a site.

The fine particles which comprise dust can become suspended and entrained in air and, as

such they can disperse from a source. They will progressively fall out of the air stream; in fact


most dust settles out close to the source. Fugitive dust is that which escapes from the

immediate vicinity of the source and may affect the area surrounding the site.

Particulate dust emissions from construction works associated with the development have the

potential to impact upon local residents, and on-site workers during the works. Dust which is

raised by onsite operations may be carried to nearby residential areas, if present in sufficient

quantities. Concerns have been raised by the inhalation of dust particles and the possible

health effects this may have. This has the potential to impact upon local residents and on-site

workers.

Where mud from a development site is allowed to spread onto local roads, it can form a

secondary source of dust. The mechanical action of wheels on the road surface material will

reduce the particle sizes by crushing and the potential for emission of dust from these roads

can be quite high. As vehicle pass along the road, dust is re-suspended into the turbulent air

stream both beneath and behind the vehicle and this can become entrained into a moving air

flow. The erosive action of road traffic depends on the number and size of wheels, the vehicle

speeds and the moisture content of the surface material.

Good environmental practices will as described below will be used to control these dust

emissions, and mitigate against any nuisance problems arising.

Monitoring programme

On-going monitoring shall be undertaken by the construction supervisors on a regular basis,

both on and off site for visible signs of dust emissions and deposition originating from the site

to ensure the adequacy of the mitigation measures being employed. On site daily monitoring

of dust emissions will be undertaken for each construction activity which is deemed to pose a

risk, with records maintained.

The monitoring programme will record:

Date Activity/Location Weather Conditions Wind Direction and Speed Dust suppression method(s) implemented

Excessively windy conditions can increase the propagation of dust. The local weather forecast

will be taken into account as part of the monitoring procedure. These conditions will be noted


and the activities which have an increased risk of causing dust nuisance (e.g excavations and

earthworks) during windy conditions will be restricted or the mitigation level increased.

Construction supervisors will assess if the weather conditions are appropriate for the types of

activities being undertaken.

Any complaints in relation to fugitive dust will be logged and appropriate action taken by site

management in accordance with the Complaints Protocol (Planning Condition 56) to ensure

any further potential for complaint is minimised. Logs of any complaints will be made available

to the LPA.

Mitigation Techniques

Mitigation measures will be implemented to ensure effective control of dust emissions from the

construction works. These are industry best practices. The best practices are proven, well

established, techniques to mitigate nuisance dust emissions.

The mitigation measures proposed in this plan are based on guidance provided by the

following documents;

The BRE Guidance Document, controlling particles, vapour and noise pollution from construction sites.

London Best Practice Guidance, The control of dust and emissions from construction and demolition.

General mitigation techniques for the various construction activities will include:

Activity Mitigation measures

Construction

Traffic All construction traffic shall follow specifically designated routes Speed limits shall be put into place on site for all vehicular movements All vehicles carrying loose material shall be covered Wheel wash facility shall be used for vehicles leaving site

Highways Where necessary, use of road sweepers shall be incorporated to ensure highways remain clear of dust and mud

Road edges and pathways shall be swept by hand and damped down as necessary Stockpiles To be damped down enclosed or covered as appropriate.

To be sealed or sprayed with chemical bonding agents as required Location of stockpiles away from any sensitive receptors wherever possible

Dust

Suppression Mobile bowsers to be deployed on site at regular intervals as necessary. Monitoring and mitigation activity to be increased during significantly dry and windy


Activity Mitigation measures

periods

Where necessary, use of enclosures to be considered to ensure reduction in dust migration

Deliveries of significantly dusty materials to be sprayed to reduce dust potential All cutting and grinding operations to be conducted in ways to reduce risk of dust

migration (wet cutting techniques etc.)

There will be a complete prohibition on the burning of any materials on the site during

construction.

Mitigation equipment will be readily available on site from the commencement of the works.

These will include sheeting, and damping equipment; such as, tractor bowsers, road sweepers

etc.

Where processes are intrinsically dusty and alternative processes exist which are less dusty,

these will be implemented. Prefabricated components and construction will be used wherever

possible to minimise the need for on-site construction which may cause the emission of dust.

Suitable control procedures for minimising dust during the various construction phases

The scale of the preliminary works, (Stage 1), is minor in comparison to the main construction

works (Stage 2). Stage 1 provides the enabling packages to ensure the Main Construction

works can be undertaken without logistical restrictions.

Stage 1 comprises;

Wolseley Road junction improvements The junction improvements involve minor road-works including traffic island

modifications, new traffic signals and resurfacing.

Access road from Camels Head RN4 car-park to the main construction site Security Fencing Bull Point access road Erection of Acoustic Barriers Setting up of the main site establishment Further site investigation works on the main construction site (including relocation

of exiting stockpiles and earthworks to facilitate the works) and access road bridge

areas.


These elements will incorporate small scale earthworks. The fence will be erected manually

without the need for craneage.

All sensitive receptors are a consideration during these works. However as a result of the

scale of the operations required the nuisance potential is reduced with smaller scale plant,

smaller work areas and a reduced frequency/duration of relevant activities.

Earthworks and piling (Main construction months 1 to 8)

Excavations, piling, loading and unloading of materials on-site and stockpiling of materials

have the potential to be a major contributor to dust emissions. During excavation, previously

stable surfaces are disrupted and exposed to the wind. As these materials are generally dry

they can easily become suspended by the wind or mechanical disturbance and readily

become airborne in significant quantities.

Surfaces will be disturbed as little as possible and where necessary stabilised as soon as

possible after disturbance by damping down with water sprays to minimise dust emission and

re-suspension.

Where the construction logistics on site allows stockpiles will be located away from areas of

the site close to the sensitive receptors. All stockpiles will be treated with water sprays to

prevent dusting or covered correctly with secured tarpaulins where necessary.

Reinforced concrete structures (Main construction months 2 to 13)

The fabrication and construction process will involve the construction of reinforced concrete

(RC) foundations and structures . There is potential for the emission of dust in both open and

enclosed areas during the RC construction stage and mitigation methods are necessary to

reduce these.

Off site fabrication and construction will be used wherever possible. If this is not possible, the

fabrication processes will be undertaken away from sensitive receptor areas.

Dust suppression methods will be implemented by using fixed enclosures or equipment with

water sprays, local exhaust ventilation or particle extraction/minimisation systems.

Mixing of concrete will occur off site and be directly delivered to the required area of the

construction site. On site batching will not be used. Any small scale mixing requirements will

be undertaken in shielded areas away from sensitive receptors.


Dry sweeping will be avoided and damp sweeping using a fine mist will be used. Washing and

damping down will be implemented as required.

Materials handling (throughout the construction period)

A wide range of materials will be handled during the construction phases of the development

and the handling of these materials has the potential to create dust emissions. Generally the

use of dry or powdery material on site will be minimised. The following precautions will be

implemented to minimise dust emissions arising from materials handling;

Material drop heights will be minimised,

Damping down will be used to reduce dust emissions. in dry, hot weather damping down frequency will be increased,

Steep sided stockpiles or mounds or those with sharp changes in shape will be avoided, Heights of stockpiles will be restricted to mitigate airborne dust potential.

Wherever possible stockpiled materials will be kept away from the site boundary and sensitive receptor locations and damped down, enclosed or securely sheeted

as appropriate.

Wind barriers will be used to protect stock piled loose material and skips will be enclosed or covered, Lorries will be covered and closed tankers will be used for

transporting dry and fine powdery materials,

Materials delivered to site will be left wrapped until needed,

Methods and equipment will be in place in case of spillages. The site will be regularly inspected for spillages and wet handling methods for cleaning up spillages

such as cement powder will be used.

Site, Access and Public roads (throughout the construction period)

During development it will be necessary to construct access and site roads to accommodate

vehicle and plant movements on the site and for delivery of required materials.


Unpaved site roads can greatly contribute to dust emissions, especially in dry or windy

conditions therefore compacted hard surfaces will be used wherever possible, even if the

routes are only temporary. Traffic on site roads located close to sensitive receptor locations

will be kept to a minimum where construction requirements allow.

Vehicle movements and behaviour on site will be controlled by appropriate signage and

compliance will be monitored by construction site supervisors. Vehicles will be restricted to a

minimum commensurate with the construction requirements and speeds will be limited to 5

mph on un-surfaced roads and 10 mph on properly surfaced and maintained roads. This will

contribute to the reduction in the re-suspension of dust as a result of the movement of

vehicles.

Site roads will be inspected regularly and kept in a compacted condition using static sprinklers,

bowsers, low emission additives and binders if necessary. The access road to the main

construction site will be cleaned daily during the working week and more frequently if

necessary using a mechanical road sweeper. Edges of the access road and footpaths will be

cleaned with a hand broom and controlled damping.

Damping down techniques used to minimise the re-suspension of dust into the air can also

cause the build up of mud and dirt on roads which is picked up by vehicle wheels. Therefore

wheel washing techniques and rumble grids will be implemented, before vehicles enter public

highways, to prevent the transportation of mud and dirt off site.

During the preliminary works simultaneous activities will be taking place in a number of

locations both inside and outside the naval base and therefore multiple wheel wash facilities

will be established in this period. Due to the short term nature of these works these facilities

will take the form of a manually operated high pressure jet wash located in the positions

indicated on the drawing included in attachment 7. Vehicles leaving the construction areas will

be inspected at the wheelwash points and thoroughly cleaned as required.

During the main construction works a permanent wheel wash facility with bunded enclosure

will be installed on the access road at the exit point of the main site in the position indicated on

the drawing included in attachment 8. The wheel wash will be the same as or of a similar

standard to that shown in attachment 9.

Asbestos

The main risk from asbestos in soils is the potential to liberate fibres into the air, as a result of

attrition of cement products and or disturbance of the soil, and which may subsequently be

inhaled. Post development, in those areas of the site covered by hardstanding, the risk to


human health will be negligible since the hardstanding will present a barrier to the liberation of

airborne particulates including asbestos fibres. However, there may be a potential increased

risk during construction related activities such as piling where significant ground disturbance

may take place.

Although the available information does not suggest the widespread presence of asbestos

containing material within the fill deposits at the site, occasional asbestos containing material

has been identified which if disturbed may have the potential to liberate asbestos fibres into

the air and will therefore need to be appropriately managed. The following protocol for

managing asbestos containing material (ACM) that may be encountered at the Site during will

be adopted:

All pile arisings comprising of fill materials should be subject to routine damping down as piling progresses.

A person competent in identifying all types of ACM should be present on Site at all times to inspect pile arisings.

Any arisings where ACMs are identified should be separated, damped down further and covered by plastic sheeting or similar.

The management of arisings in this way should be maintained until the material can be removed from site for appropriate disposal.

If ACMs are encountered, air monitoring should be undertaken in the immediate vicinity of and downwind of the works. The air monitoring should be maintained

during ongoing works whilst a source of ACMs is present on site in order to

demonstrate the effectiveness of the control measures, such as damping down and

covering, being employed.

It will be necessary for an appropriate asbestos air monitoring contractor to be retained who

can attend the site to undertake air monitoring, as detailed above at short notice should ACMs

be identified.

Site specific procedures will put in place to identify testing regimes and what to do in the event

of asbestos being found. This will vary on the type of asbestos found and its condition as to

the level of decontamination, segregation, remediation etc. Specialist advice will be obtained

to complete such a procedure

If asbestos is identified during excavation works then activities will stop in the area, and the

area quarantined whilst a specialist is employed to clear the contamination.


The most effective control of the harmful particles is by means of dust control. If asbestos is in

the ground then it is usually wet or bound up with mud / soil / organic material etc. therefore,

the risk is reduced. The best practice control measures already outlined will ensure this risk is

minimised.

Selected site personnel will be trained in asbestos awareness and will be able to identify the

material if encountered. If this event is realised the element of work affected will be suspended

and the area segregated prior to the necessary remediation strategy being implemented.

Mitigating exposure of on-site workers

Whilst it is important to minimise the impacts of the works on local residents and other

sensitive receptors, it is also necessary to consider the effects of exposure to dust on site

workers during the various construction phases.

Training will be provided for all on-site workers regarding suppression of pollution emissions

and minimising exposure to potentially harmful emissions. Appropriate PPE will be worn as

determined by the risk assessment for the relevant activity.

Workers will at all times reduce their exposure to emissions. Excessive time will not be spent

by one person on one activity which is inherently dusty.

Wherever equipment is being used within enclosed spaces, ventilation or particle extraction

systems will be used at all times.

4.3 Noise

Background information

Like dust, the generation of noise beyond of the site boundary is a potential source of statutory

nuisance and can lead to complaints. Such complaints, if upheld, can lead to legal action

which causes resultant delays and costs to the project. The site is directly adjacent to various

residential areas making construction noise a particularly sensitive issue to local residents

A basic element in the mitigation of nuisance due to noise is adherence to acceptable working

hours. All works shall be undertaken in compliance with the working hours specified in

Plymouth City Council's "Code of Practice: Control of Pollution & Noise from Demolition &

Construction Sites" ie:


Monday to Friday 8am - 6pm Saturday 8.30am - 1pm No Sunday, Bank holiday or Public holiday working

Should work be required outside of these hours prior permission must be sought from the local

authority including details of any noise that may result from the activities.

Construction site noise has the potential to impact upon the current amenity of local residents.

The EIA has identified the following properties as sensitive receptors to noise and vibration:

C1: 25 36 Talbot Gardens C2: 1-12 Talbot Gardens C3: 13-18 Savage Road C4: 471 Wolseley Road C5: 21 Hamoaze Avenue

The locations of these receptors in relation to the site are shown in attachment 11.

Good relations with people living and working in the vicinity of site operations are of

paramount importance. Early establishment and maintenance of these relations throughout

the carrying out of site operations will contribute towards allaying peoples fears. Good

relations can be developed by keeping people informed of progress and by treating complaints

fairly and expeditiously.

Noise can also interfere with working efficiency of site workers by inducing stress, by

disturbing concentration and by increasing accident risk. Effects of noise on persons on site

are similar to the effects on nearby residents, and the benefits of good control measures will

apply equally on and off site.

Noise Monitoring Programme

Noise levels will be monitored at the sensitive locations nearest to site during the main

construction works in accordance with a Noise Monitoring Plan to be agreed with the LPA in

accordance with the requirements of the S106 Agreement. The noise monitoring programme

will be undertaken by suitably qualified specialist consultants. All noise level monitoring

equipment used will be well maintained and calibrated in accordance with manufacturers

guidance. Logs of all noise monitoring will be kept within the site files and will be made readily

available for inspection. The following will be noted at each identified sensitive receptor when

noise monitoring is being undertaken.


Time Weather conditions and wind direction Location of monitoring Background noise level LAeq dB reading over the relevant time period

All results will be monitored against the predicted noise levels detailed within the Acoustic

Technical Note dated 28-7-11 in compliance with planning condition 19. Where noise levels

from any activities are outside of the predicted levels the LPA will be informed immediately

and alternative or additional mitigation methodology will be investigated and implemented.

Where any noise complaints are received, these will be thoroughly investigated by the site

management in accordance with the Complaints Protocol (Planning Condition 56) and actions

implemented to ensure repetition of the issues are avoided.

Site Investigation and Assessment

Planning condition 19 requires compliance with the construction noise levels predicted in the

Acoustic Technical Note dated 28-7-11 which provides a technical assessment of the

predicted noise levels from the various construction phases in comparison with the 10 hour

period acceptable noise levels given in the PCC Code of Construction Practice. The mitigation

detailed in this document is intended to reduce the construction noise to the predicted levels in

the assessment.

Noise Control Measures

A number of control measures will be implemented at the site to minimise noise. These

measures are developed from current best practice and the BRE Pollution control Guide: Part

1 Pre-project planning and effective management. In particular the following control

measures will be applied;

Acoustic barriers for static activities will be used where necessary and practicable. The extent to which this can be done depends on the nature and mode of operation

of the machines to be enclosed and the ventilation requirements, in particular and

where practicable, acoustic barriers shall be provided when working in the vicinity

of properties on Talbot Gardens,. This will provide additional mitigation for the

short-term significant construction noise effects at these properties.


A permanent acoustic barrier is to be installed along the new access road providing mitigation for residents off Wolseley Road Hamoaze and Harbour Avenue.

All construction plant and equipment shall comply with EU noise emission limits. All vehicles and mechanical plant used for the purpose of the works shall be fitted

with effective exhaust silencers.

Selection of inherently quiet plant. All major compressors, generators etc. shall be sound reduced models fitted with

properly lined and sealed acoustic covers which shall be kept closed whenever the

machines are in use and all ancillary pneumatic percussive tools shall be fitted with

silencers of the type recommended by the manufacturers.

Machines in intermittent use shall be shut down in the intervening periods between works or throttled down to a minimum.

Materials shall be delivered during normal site working hours. All ancillary plant such as generators, compressors and pumps shall be positioned

so as to cause minimum noise disturbance, i.e. furthest from receptors or if

necessary, behind acoustic enclosures and /or shielding. Where possible, loading

and unloading will also be carried out away from such areas,

Constant monitoring and review of operations Monitoring of feedback from local residents during site activities Site training and awareness for all site personnel with regard to behaviour on site to

minimise nuisance and engender a considerate approach.

Modification of existing plant and equipment. Noise from existing plant and equipment can often be modified at source if necessary or improved sound

reduction methods can be applied,

Maintenance: Regular and effective maintenance by trained personnel is essential and will do much to reduce noise from machinery. Increases in plant noise are often

indicative of future mechanical failure. Regular maintenance will form part of an

effective housekeeping management programme.

The hours of operation of all plant and vehicles will be limited to the normal site working hours and any use of equipment outside of these hours will be avoided,

The drop heights will be minimised as much as possible, No plant or machinery will be left running unnecessarily. Plant and equipment such as flatbed lorries, skips and chutes will be lined where

possible with noise attenuating materials,

Materials will be handled as carefully as possible when loading lorries and skips to minimise noise,

Queuing of vehicles wanting to enter the site will be minimised and a policy relating to this will be clearly set out in the site rules,


Whilst reversing alarms do present audible impact their necessity is a reflection of the high risk

associated with reversing vehicles. They must be distinct to ensure they are audible above

background noise. Despite their need, mitigation can be introduced to prevent nuisance to

residents. The site layout will introduce and maintain one-way vehicle movements with

unloading areas and lay-bys to prevent the need for vehicles to reverse. Any reversing areas

needed or introduced will be located away from sensitive receptors. Pre-established reversing

areas will also allow additional acoustic barriers to be introduced to provide further mitigation.

All practicable additional measures will be taken to minimise nuisance from reversing alarms

Project Specific Elements

The scale of the preliminary works, (Stage 1), is minor in comparison to the main construction

works (Stage 2). Stage 1 provides the enabling packages to ensure the Main Construction

works can be undertaken without logistical restrictions.

Stage 1 comprises;

Wolseley Road junction improvements The junction improvements involve minor road-works including traffic island

modifications, new traffic signals and resurfacing.

Access road from Camels Head RN4 car-park to the main construction site Security Fencing Bull Point access road Erection of Acoustic Barriers Setting up of the main site establishment Further site investigation works on the main construction site (including relocation

of exiting stockpiles and earthworks to facilitate the works) and access road bridge

areas.

These elements will incorporate small scale earthworks. The fence will be erected manually

without the need for craneage.

All sensitive receptors are a consideration during these works. However as a result of the

scale of the operations required the nuisance potential is reduced with smaller scale plant,

smaller work areas and a reduced frequency/duration of relevant activities.

The project will incorporate the following major elements of construction during the Main

Construction Works;


Earthworks and Excavations (Main construction months 1&2)

Fully detailed planning will use suitable methodology to ensure noise impacts are minimised

using the appropriate mitigation methods selected from those outlined above.

Rotary Bored Piling (Main construction months 2 to 8)

Piling activities have the potential to create the most significant noise impact. Three piling rigs

will be in use simultaneously but in different areas of the site and this was taken into account

in the noise predictions made in the Acoustic Technical Note dated 28-7-11. Tthe trial piling

operations provided further practical assessment of the potential noise levels that may be

encountered. Whilst the resultant noise levels recorded were generally below those predicted

in the test piling planning application further lessons were also learned. The element of the

piling activity resulting in the highest level of noise was the cleaning of the drill string when

drilling debris was shaken from the drill string. Significant improvements will be made with a

mechanical application to clear the drill string upon extraction without the need for the vigorous

shaking witnessed during the trial piling works thereby reducing this element of noise

generation.

Consideration was given to restricting the daily hours for piling operations however since there

is a fixed number of piles that have to be installed this simply results in a corresponding

extension to the total duration of the piling and construction period overall and has

consequently been discounted.

Reinforced Concrete Construction (Main construction months 2 to 13)

Fully detailed planning will use suitable methodology to ensure noise impacts are minimised

using the appropriate mitigation methods selected from those outlined above.

Steelwork and Cladding Erection (Main construction months 14 to 21)

Fully detailed planning will consider suitable methodology to ensure noise impacts minimised

using the appropriate range of mitigation methods from those outlined above.

Reinforced Concrete Construction and Steelwork and Cladding Erection activities will be

planned so that wherever possible walls and structures closest to the sensitive receptors will

be constructed first so as to provide acoustic barriers for the subsequent construction

activities.


Construction traffic (throughout the construction period) - Sensitive residential receptors have

been identified as the properties on Wolseley Road, Weston Mill Drive and the Weston Mill

Community Primary School. The noise levels in these locations are anticipated to be

increased by less than 1dB(A) and the risk is assessed as negligible. The acoustic barriers

that will be erected along the new access road will provide mitigation to receptors in the

Hamoaze Avenue area for construction traffic accessing the site.


4.4 Vibration

Initial assessments undertaken during the environmental impact assessment indicated that the

works should not pose any significant risks in relation to vibration. However, if it becomes

apparent that vibration may give rise to an environmental impact a full investigation shall be

undertaken by the site manager using where necessary external specialist consultants to carry

out monitoring at the receptor locations.

Best practice techniques shall be utilised at all times to minimise vibration from construction

activities. Speeds will be limited to 5 mph on un-surfaced site roads and 10 mph on properly

surfaced and maintained site roads.

Any complaints relating to vibration disturbance will be fully investigated by the site

management team in line with the Complaints Protocol (Planning Condition 56).

4.5 Light Disturbance

It will be necessary particularly during darker months to light the construction site and office

complex and there is the potential for poorly aimed or controlled lighting to intrude or irritate

local residents.

Possible sources of nuisance are

Light trespass light spilling beyond the boundary of the property on which a light is located, sometimes shining through windows and curtains.

Glare the uncomfortable brightness of a light source when viewed against a darker background

The major mitigating factor is the project working hours. (0800-1800, Monday to Friday), this

will prevent the more severe element of intrusion, ie sleep deprivation, being realised.

Due to the location of properties nearby to the site, consideration shall be given to the location

and angle of site lighting to ensure minimum potential for disturbance to local residents. The

sensitive receptors are those nearest to the site namely;

C1: 25 36 Talbot Gardens


C2: 1-12 Talbot Gardens

The following mitigation and best practice will be implemented

Lights will where practicable, be positioned facing away from residential properties, however adequate lighting of working areas is an essential safety consideration

and where this is not possible lighting units will be placed in such a way as to pose

minimal risk of light disturbance. Unless health and safety requirements dictate

otherwise, no lighting shall face towards any property identified as a sensitive

receptor.

Lighting will be directed towards the site activity so as to avoid the possibility of any lights shining directly onto nearby residential properties

Lighting will be suitable for the application Unnecessary lighting will be removed Lights will be switched off when they are not needed; this will include periods

outside of normal site working hours.

Any security lighting will be kept to a minimum at all times and powered by mains supply.

Checks will be made each evening to ensure no lights are left on in error

Any complaints relating to light disturbance will be fully investigated by the site management

team in line with the Complaints Protocol (Planning Condition 56).

4.6 Heritage and Archaeology

Initial assessments in the environmental impact assessment do not anticipate that there are

any archaeologically sensitive areas within the site boundaries. However, the following

procedures shall be followed in the event of such a find or discovery:

Immediately stop works in the area of the find Protect the find and the area surrounding by fencing/blocking off and immediately

contact the Site Manager

Contact an archaeologist and obtain advice on how to proceed All significant finds must be reported to the County Archaeologist

The County Archaeologist in charge will be contacted by the site management. The contact

telephone number is: 01752 305433/304397.


4.7 Waste Management

The site will implement a Site Waste Management Plan (SWMP) which describes the

procedures for management of waste arising from the construction activities. The SWMP shall

comply with the Site Waste Management Plans Regulations 2008.

The project shall utilise the BRE SMARTWaste online tool as its method of meeting the Site

Waste Management Plans Regulations and recording the movements of wastes from the site.

4.8 Water

A stream known as Weston Mill Creek and a small tributary known as Barne Brake are located

in close proximity to the site boundaries which discharge into Weston Mill Lake with the tidal

range extending upstream beyond the site and it is essential that no contaminants enter this

water course.

Betterment of the aquatic ecological environment shall be achieved by removal of a disused

culvert with footway over the Barne Brake. The creek bed shall be returned to its natural state

and an extensive clean-up of the rest of the creek between Wolseley Road and the site shall

be completed.

Following this a schedule of marine litter monitoring and removal shall be implemented in

accordance with the scheme agreed with the LPA in accordance with the planning conditions.

Mitigation

The following mitigation measures shall be employed:

All necessary consents shall be applied for prior to commencement of works e.g. Land Drainage Consent shall be requested from the Environment Agency under the Land

Drainage Act of 1991.

The design of the new development has been significantly influenced by the need to ensure protection of the water environment, for example, the span of the new bridge

shall keep the new abutments clear of the water.

The existing sheet pile abutments shall be extended, as well as new abutments constructed so that any loose material cannot enter the watercourse.

The excavations shall be dewatered as necessary and all pumped water shall be discharged through a series of Siltbuster settlement tanks before it is allowed to enter

the stream.


Spill kits shall be made available, and site operatives trained in their use, to deal with any spillages of materials likely to contaminate the watercourses. All spill kits shall be

fully stocked at all times and an inventory of equipment within the container shall be

clearly displayed on the lid.

Due care and attention shall be given to the prevention of surface run-off. For example, stockpiling of materials within the vicinity of the watercourses shall be

discouraged. Where stockpiles have to be located in the vicinity of a watercourse a 7

m buffer strip shall be in place to reduce pollution risks.

A temporary swale shall be installed along the eastern side of the site, into which runoff can be directed to reduce silt and suspended solids before discharge into the

watercourse.

The positioning of fuel storage tanks and other potentially polluting materials and maintenance/refuelling facilities shall be on areas of hard standing with dedicated

drainage systems. Stored materials on site shall be checked regularly for containment

integrity (both primary and secondary), quantity stored and security of storage.

Monitoring

Monitoring shall be as follows:

Short term surveillance monitoring shall be undertaken in advance of construction in order to establish a baseline. The short term surveillance monitoring shall include

specific water quality monitoring for shallow groundwater and surface water and

assessment of existing Water Framework Directive data regarding the ecological

status of the watercourse.

Further surveillance monitoring shall then be undertaken during construction. Regular weekly monitoring and water sampling shall be undertaken at specific points, these

inspections shall include as a minimum visual reference, turbidity and pH levels.

In addition to this, during the more environmentally risky operations such as piling or concrete placement, the stream shall be continually visually monitored for turbidity and

any impending risk of contamination. Plant maintenance checks shall also be

increased in frequency during these operations.

In periods of heavy rainfall or excessive vehicle movements within the vicinity, monitoring shall be increased to reduce risks of pollution incidents.

Construction of concrete structures during the construction phase shall be monitored to prevent associated contaminated material entering any watercourses. Pre-cast

work or permanent formwork shall be used where possible to reduce the amount of in-

situ concreting required adjacent to and above the watercourses. Washing out of

concrete wagons or other equipment used in concreting operations shall only be


undertaken in designated contained washout areas. These shall be located away from

all watercourses and drains and shall be impermeable to prevent infiltration to ground.

Piling activities required for the waste bunker and building foundations may extend down to the Secondary (B) Aquifer (Saltash Formation). A Foundation Works Risk

Assessment shall be prepared by the Contractor to confirm that the risk of

contamination of the Secondary Aquifer through the mobilisation of contaminants

within the made ground is low with the proposed use of rotary bored piles. The risk

assessment shall be agreed with the Environment Agency.

Where over pumping is required, the water shall be put through an appropriate sized settlement tank, the flow rate set up shall allow appropriate timescales for settlement.

If the discharge is still showing as heavily silted, then a Silt buster settlement tank (or

series of) shall be used with flocculants if appropriate.

Permission for any dewatering activities shall be sought from the Environment Agency under the terms of the Water Act 2003, well in advance of the dewatering activity

commencing.

All records of water monitoring inspections shall be kept on site throughout the duration of the project and be readily available for inspection by the relevant

authorities.

4.9 Transportation and Traffic Management

A Construction Traffic Management Plan (CTMP) shall be implemented on the site. The plan

shall outline timings of deliveries and routes to be taken by construction vehicles to ensure

minimal disruption to local residents and businesses. This shall include potential risk for noise

disturbance as well as minimising additional traffic during peak periods. The CTMP is provided

as a separate document.

4.10 Ecological Management

The existing ecological features could potentially be affected by the proposed construction

works. However, the initial environmental impact assessment concluded that if appropriate

mitigation and enhancement activities were to be undertaken then the impacts would not be

considered significant.

General Ecological Mitigation

The following mitigation measures will be employed. Refer also attachments No 1 and 2 -

Wildlife and Construction Best Practice Guidance. These posters will be prominently displayed

on the site on notice boards on the site and in site cabins and offices.


Dust minimisation methods shall be employed Construction lighting shall be directed away from retained areas of habitat wherever

possible.

Security lighting and non-essential lighting shall be fitted with automatic cut-off switches where practicable.

Pollution prevention controls shall be utilised to reduce the risk of sediment pollution resettling further downstream and potentially smothering benthic habitats (see section

4.8).

All tree and vegetation clearance works within the area defined on the Vegetation Clearance Plan dated 1st May 2012 and Drawing No 47031683 300 Rev C shall be carried out under the supervision of an experienced ecologist to prevent disturbance

to nesting birds and other protected species. Where vegetation clearance is being

carried out in teams, each team will be accompanied by an experienced ecologist.

The ecologist will check and observe each 20m sector of vegetation for approximately

20 minutes prior to clearance works commencing. If an active bird nest is detected at

any point, works in that sector will immediately cease and an area of 5m radius around

the nest will be cordoned off and clearly marked using hi-visibility tape and appropriate

signage to prevent disturbance to nesting birds. Any noisy machinery such as chippers

will be moved at least 10m away from the location of the nest. Works within the

cordoned off area where active bird nests have been detected will only proceed once

an experienced ecologist has confirmed the nests are no longer active.

As an additional measure, throughout the duration of the proposed tree and vegetation

clearance works, a falconer will be employed Monday to Friday for at least two hours a

day to act as a deterrent to birds wishing to nest on site. The falconer will walk a

continuous transect covering the periphery of the areas to be cleared as shown on the

Vegetation Clearance Plan dated 1st May 2012 and Drawing No 47031683 300 Rev

C any other areas where it is necessary to deter nesting birds..

Where any unexpected species are identified by any personnel on site, all works within that area shall cease immediately. Site management shall be immediately

informed and they shall contact the project ecologist. No further work may take place

within that area until permission has been given by the project ecologist and site

management.

The contact details for the Project Ecologist are Paul Gregory or Melanie Pritchard; URS Infrastructure & Environment UK Limited, Mayflower House, Armada Way,

Plymouth, PL1 1LD, United Kingdom telephone 01752 676700


Bats

The site is considered to be of negligible conservation value for roosting bats and low

(parish/neighbourhood) value for foraging/feeding and/or commuting habitat for bats.

Reptiles

Reptiles are protected creatures making it an offence to intentionally and recklessly kill, injure

or take from existing habitats. A reptile survey has been undertaken and a translocation

habitat area identified and a reptile barrier has been installed separating the translocation area

from the site works. The reptile barrier will be maintained throughout the duration of the

project. A series of trapping visits was commenced in 2011 and 48 of the 60 required visits

have been carried out prior to the temperature dropping and the reptiles going into hibernation. As reptiles were still being trapped up to hibernation, the site cannot be declared clear until the

remaining visits have been concluded.

It is planned to re-commence the trapping visits in April 2012 providing the ground temperature

is conducive for reptiles to come out of hibernation. It is anticipated that the remaining 12 visits

will take approximately 2 weeks

Under current guidance / legislation / best practice a period of 5 clear visits must be achieved

in order to demonstrate that all practicable efforts have been made to trap a significant number

of reptiles, if they are present on site. However in order that construction works can continue in

the event that the conditions have not been suitable to carry out the remaining visits, the

project ecologist has confirmed the following:-

The largely flat, well compacted, barren areas of the site would not be conducive for reptile habitat; therefore, works can be carried out on these areas.

The stockpiles of crushed aggregate located on the Eastern side of the site are not suitable for reptile habitat; therefore, this material can be excavated and used.

The stockpiles of crushed and un-crushed aggregate located on the Western side of the site could be suitable habitat; therefore, these areas should be avoided until reptile

clearance has been completed.

The earth bund around the site may contain reptiles and should be avoided. However, once the conditions are suitable, these areas could be cleared or excavated under a

watching brief by the ecologist in a controlled manner.

The side slopes and lower area around the site (MOD security patrol zone adjacent to the security fence) may be reptile habitats and should be avoided. However, once the


conditions are suitable, these areas could be cleared, excavated or filled under a

watching brief by the ecologist in a controlled manner.

Table Top Mountain is not suitable habitat; therefore, the planned mobilisation works i.e. site facilities set-up, installation of temporary security fence, repositioning MOD

CCTV masts and cameras etc can be carried out without further ecologist supervision.

Bull Point Access Road is not ideal reptile habitat but could suit nesting birds, therefore, this area should be cleared under a watching brief as soon as possible to

mitigate any risk.

New Access Road is not reptile habitat but has areas suitable for nesting birds and therefore should be trimmed / coppiced / cleared as soon as possible under a

watching brief to mitigate any risk.

Planned early works or the main works should not be adversely affected by the possibility that reptiles are still present on site as the risk can be managed and

mitigated with early clearance of suitable habitats and / or works being undertaken

under a watching brief.

Briefings about the reptiles on site shall be included as part of the induction process. Regular toolbox talks shall be held prior to any construction activities commencing, re-

iterating the ecological issues.

Species identification training and posters shall be available on site to assist all site personnel with identification (See attachments 1 and 2).

In the event of the discovery of any reptiles during the construction works, immediate

surrounding works shall cease. The site foreman shall contact the site manager, who shall in

turn contact the ecologist. No works may commence within the area until an ecologist has

given permission.

Flora

Site preparation works includes the levelling of earth mounds and clearance of areas of scrub

and trees using specialist contractors.

Individual trees and tree groups not requiring removal shall be protected in accordance with

BS5837:2005 Trees in Relation to Construction. A Tree Protection Zone shall be established

within which no work shall take place without the prior authorisation of a suitably qualified

arboricultural consultant. Clear signage shall be placed on all fencing surrounding the

protected tree area. The fencing shall be regularly checked and any areas found to be of poor

quality or damaged, shall be repaired or replaced immediately. All site personnel shall be


made aware of which areas are not to be entered within the Induction Programme and this

shall be reinforced throughout the duration of the works through regular toolbox talks.

The existing Blackies Wood habitat shall be managed to promote the wildlife which already

exists.

Landscape design shall incorporate native planted woodland and shrubs that shall represent

the existing landscape character; the creation of wildlife corridors boundaries; the

reinstatement of an existing ditch to connect to a newly created freshwater pond; areas of

open species-rich neutral grassland and bird, bat and insect boxes.

The Japanese knotweed within Blackies Wood and on the slopes of Table Top Mountain

(outside the site boundary but adjacent to the construction compound) shall be treated and

eradicated to halt the spread of this invasive species.

4.11 Land contamination

Ground investigations at the site have not encountered significant contamination of either soils

or groundwater and the ground has been classified as suitable for commercial and industrial

use and it is intended that all excavated material shall be re-used on the site.

There is a potential risk to off site receptors from emissions of contaminated dust but the

Environmental Statement identified that the risks from contaminated dusts are deemed to be

low due to the lack of significant contamination within the site soils and will be further

controlled with good working practices and the implementation of dust control measures

during the construction works as described in Section 4.2 above.

During the site induction all personnel shall be made aware of their responsibility to be vigilant

with regards to identification of potential soil contamination. Key personnel in this respect are

ground workers, machine operators and their banksman. Training will be provided to

supervisors to provide the necessary awareness to identify areas of contamination.. They will

report any suspicions of contaminated soil or groundwater to the site management.

If unforeseen contamination is encountered during site works, the specific element of work will

be suspended and the area will be segregated. The result of any notification will also be

reported to the LPA and the Environment Agency, remediation options shall be considered

following assessment and identification of contaminants. Any remediation process shall

comply with all legislative and best practice guidance.


Should any excavated soils need to be removed from site for disposal to a landfill the soils

shall undergo Waste Acceptance Criteria (WAC) testing in order to correctly classify the

material in terms of waste disposal. The results of the WAC testing shall be supplied to the

chosen waste acceptor at an early stage of the process in order to locate a suitable landfill

site.

Excavations and Stockpiles

All stockpiled material will be located away from sensitive receptors with suitable bunds and

/or barriers to prevent cross contamination as a result of run-off.

Deep excavations always pose a potential hazard with regard to encountering contaminated

materials or the build up of hazardous gases. Methane was detected at depth in one location

on the site during the ground investigation but no evidence of elevated levels were detected

elsewhere across the site.

Strict Health and safety precautions will be implemented for all excavations and this may

include the use of gas monitors should the need be defined from a thorough risk assessment

of the activity being undertaken. The risk assessment will identify the necessary actions to be

taken in the event of activation of any gas alarms.

4.12 Resource use

MVV shall ensure where practicable, that the use of recycled or sustainable materials shall be

utilised. All wood should be obtained from a certified sustainable source, such as FSC.

MVV shall ensure that up to fifteen per cent (15%) and at least a minimum of ten per cent

(10%) of total material value of the civil construction and building works derives from reused

and recycled content in new build. Appropriate opportunities shall be accepted to exceed this

figure without increasing the cost of materials.

A dedicated area shall be maintained for storage of all materials and due care and appropriate

handling shall be undertaken at all times to reduce any risk of damages and wastage.

Packaging of items should not be removed until required, to ensure maximum potential for

returning of unused goods.

As much office waste as possible shall be sent for recycling and also strategies are to be put

in place to ensure minimal wastage on site, for example avoiding unnecessary printing etc.

Where possible, use of local suppliers shall be considered to reduce transportation costs and

maintain a low carbon footprint.


Waste disposal options shall be investigated to ensure minimal transportation requirements

where possible. Onsite crushing and reuse of materials shall be incorporated into the project.

This shall aid reduction in waste going to landfill as well as minimising vehicular movements

on the local road systems.

4.13 Energy Consumption/Monitoring

Switch it Off schemes and other energy saving campaigns shall be implemented on site to

encourage all personnel to consider their carbon footprint. Use of car sharing and buses shall

be encouraged as outlined in the CTMP. Posters shall be clearly displayed within the site

offices to ensure all personnel are aware of the CTMP requirements. This shall also be

covered within the site induction and regular toolbox talks held relating to the subject.

4.14 Water usage

Within site accommodation taps shall be switched off when not in use and all staff shall be

made aware of water saving techniques. Every effort to ensure reduction in water use shall be

implemented where available.

4.15 Visual Amenity

The environmental impact assessment process identified that the construction process posed

a potentially short term impact. The following mitigation measures shall be deployed to

minimise the impacts;

The proposed Devon hedge bank and avenue planting are to be implemented at the earliest opportunity upon commencement of construction. This is to allow maximum

time for establishment prior to completion and operation.

Visual issues should be considered in deciding upon the need for lighting and its location and specification. Temporary lighting should use suitable lamps with flat glass

lanterns and cut-off beams in order to minimise light spillage.

Provision by the contractors of records of all pesticide / herbicide use. Provision by the landscape contractor of evidence that planting complies with

provenance requirements as applicable.

Weed control in general and actions taken to ensure that hazardous weeds in the area are destroyed and not spread (e.g. Japanese knotweed).

Handling of soils in accordance with British Standard (BS) 3822:2007 Topsoil; and locating, where possible, temporary materials storage mounds in areas that would



mitigate views of the proposed development for adjacent receptors and without

damaging the ecological resource.

Ensure that the site boundaries are kept clean and tidy at all times, including local roads

The site shall be securely fenced and the fencing shall be well maintained and kept free of attachments and non-site specific posters.

Damaged or unsightly fencing must be repaired or replaced as soon as possible.

4.16 Vermin

Maintenance of a clean and tidy site including vermin control is essential. An appropriate pest

control measure will be adopted as necessary. The site has already been subject to a pest

control survey and baiting programme and control measures shall continue throughout the

construction phase including;

Correct and satisfactory stopping and sealing of all disused drains and sewers where applicable

Prevention of accumulation of refuse and putrescent materials Ensuring any on-site catering facilities pay careful attention to food delivery, handling

and storage and disposal of any food waste.

A baiting and survey programme was commenced on the 12 October 2011 and a survey

report with any recommendations for further actions will be made available prior to

commencement of the main construction works.
