Dalwhinnie Quarry Dust Management Plan


Page 3 July 2018

1 Background

This Management Plan has been prepared to identify the operational aspects of

re-opening and expansion of Dalwhinnie Quarry which may have a potential

environmental effect and detail the mitigation measures in place to minimise these

effects.

2 Environmental Roles and Responsibilities

Ecological Clerk of Works (ECoW)

The project ecologist will undertake the ECoW role at Dalwhinnie Quarry.

The ECoW duties include the preparation of documentation before quarrying

commences and delivery of ecological requirements on site. The ECoW role

involves working with site personnel to avoid contravention of relevant wildlife

law, and to ensure the works comply with the ecology elements of the planning

conditions. The ECoW also will arrange that the workforce are aware of their

ecological responsibilities. This helps ensure that work proceeds in accordance

with the development plan.

Dalwhinnie Quarry is a phased development with soil and overburden stripped

from each phase of the quarry prior to quarrying commencing in that phase. Until

each phase commences there are no changes to the existing land use. The ECoW

will primarily be involved prior to mineral extraction commencing during each

phase of the quarry development. The breeding bird and protected species survey

will be updated by the ecologist for each phase prior to ground works (soil stripping

and formation of screening bunds).

The ECoW will provide toolbox talks and site inductions for site staff along with

associated notes to guide the quarry staff on their roles and responsibilities related

to any protected species identified and the legislation relating to breeding birds.

Where required the toolbox talk and induction will be updated prior to

groundworks commencing in each phase. The ECoW will also provide advice on

the protection of ecological features and protected species mitigation measures.

During rock extraction and processing at the quarry the ECoW will be contacted

for advice if any protected species are identified within the quarry or if any nesting

birds are identified. Sand Martins and Oyster Catchers can nest in or on quarry

stockpiles for example.

Quarry Manager

The quarry manager has overall control over operation of the site, this includes

scheduling production, health and safety, quality control and liaising with clients.

The quarry manager is the primary contact for environmental regulators.


Page 4 July 2018

Environmental responsibilities include compliance with legislation and company

specific procedures.

The quarry manager is responsible for ensuring the site is operating in accordance

with the procedures in Leiths EMS which meets the requirements of ISO 14001,

in addition he / she is responsible for efficient use of energy at the site in

accordance with Leiths EnMS which meets the requirements of ISO 50001.

Where Mobile Crushing and Screening Plant is operating on-site under a PPC

permit the manager is responsible for ensuring the plant is operated in accordance

with the conditions of the permit.

The quarry manager is responsible for ensuring that day to day inspections and

any remedial repairs identified are undertaken.

The quarry manager ensures that sufficient oil spill resources are maintained on

site, are located in appropriate areas and all site staff are aware of the location of

these materials and are trained in their use.

In the event of any environmental incidents the quarry manager is responsible for

both reporting, and jointly investigating the incident in conjunction with Leiths

HSEQ department.

The quarry manager liaises with the ECoW when ecological advice is required.

Plant Operators

While working at the site plant operators report directly to the quarry manager.

Plant operators are responsible for undertaking daily inspections and reporting any

equipment defects which could potentially lead to an environmental incident such

as an oil or fuel spillage.

Plant operators are jointly responsible with the quarry manager for maintaining

the site as a tidy working environment.

Where required the plant operators are responsible to ensure the dust

suppression equipment is used effectively.

Plant operators are responsible for reporting any environmental incidents to the

quarry manager such as oil or fuel spills.


Page 5 July 2018

3 Site Inspections

Daily Inspections and Record Keeping

Daily inspections are undertaken of the quarry infrastructure by the quarry

manager or designated deputy.

Company procedures require that all plant is inspected by the plant operator at

the start of their shift and all defects are recorded. Where possible the plant is

also inspected during and after each shift. Plant operators undertake daily checks

of crushing and screening plant, both to assess continued compliance with the PPC

permit under which the plant operates and to identify any defects which require

repair.

Daily inspections are also undertaken of all vehicles operating at the quarry, this

includes excavators, loading shovels, dozers and dump trucks.

Oil level checks and topping up of oil levels on wheeled plant will be carried out at

the start of daily shifts. All potential sources of leakage are included in daily

inspections; this includes fuel lines, fuel tanks and filters, oil lines and filters and

all hydraulic lines and fittings. If a potential source of leakage is noted during the

daily inspections this will be recorded and appropriate action taken. This will either

involve temporary decommissioning of plant and on-site repair of minor leaks or

decommissioning until external resources are mobilised to carry out the repair.

If the leakage is classed as minor and repair can be carried out by the staff on site

the plant will be returned to service as soon as the leak is rectified. Typical

examples of this are leaks at hydraulic fittings or minor fuel line leaks. Plant

inspection records are given to the company plant fitters prior to carrying out all

routine services, this ensures that all minor faults which have been rectified on

site are fully checked by a qualified fitter during a routine service and all routine

service intervals are met.

If the repair requires external resources the plant will be moved to a suitable

location in the quarry to ensure any leaks are fully contained. Plant will not be

moved if during transportation the leak is likely to increase.

The plant inspection sheets are signed off by the quarry manager or designated

deputy on a weekly basis. The sheets are sent to the Fleet and Plant Department

at Leiths (Scotland) Ltd head office along with a separate summary sheet

highlighting machine hours, next service hours and any areas which require repair

or replacement. A copy of all inspection sheets is retained on site.

A copy of inspection sheets from a Leiths site are included in Appendix A.


Page 6 July 2018

Internal Audits

Leiths HSEQ department undertake regular audits of each site, along with an

inspection of all aspects of the site operation, part of the audit includes reviewing

the daily inspection sheets, assessing compliance with the PPC permit under which

the plant is operating and ensuring any defects identified on the inspection sheets

have been addressed.

SEPA Audits

At other sites the daily inspection sheets covering the mobile crushing and

screening plant are made available to SEPA to help confirm compliance with the

PPC permit.

Planning Monitoring and Enforcement

An annual audit will be undertaken on compliance with planning conditions in place

at this site. This audit will include assessing compliance with all planning

conditions. This will include assessing all blast records, compliance with noise

limits and ensuring that any complaints have been dealt with in accordance with

Leiths policies and procedures.

Any areas where non-compliance or potential non-compliance with planning

conditions are identified will be recorded. Mitigation measures along with a

timescale will be agreed with the quarry manager and recorded in the audit report.

The planning monitoring report will be made available to the planning authority.


Page 7 July 2018

4 Air Pollution

There are two main potential sources of air pollution from any quarry site;

Dust and vehicle / plant exhaust fumes.

4.1 Dust / Particulate Emissions

The potential for dust generation and the measures in place to control dust at

Dalwhinnie Quarry are detailed in the Dalwhinnie Quarry Dust Management Plan

which is included as Appendix B.

Leiths normally issue a dust management plan as a stand-alone document and in

this case it has been included as an Appendix.

4.1.1 Occupational Exposure

The Health and Safety Executive have set the workplace exposure limit or WEL for

dust at 10mgm³ as an 8 hour time weighted average(1). The WEL is the British

occupational exposure limit and is set in order to help protect the health of

workers. Within a site this figure could potentially be significant if workers are

immediately adjacent to a particular operation prone to high dust emissions.

It is extremely unlikely that any residential property around a quarry would ever

experience concentrations of dust as high as this, with environmental dust levels

some 100 times less being the norm. Where standards are met within a site for

WEL in proximity to site operations then the risk to potential receptors out-with

the site is negligible.

(1)EH40/2005 Workplace exposure limits second edition containing the list of workplace exposure limits for use with the control of substances hazardous to

health regulations (as amended). Health and Safety Executive 2011.


Page 8 July 2018

4.1.2 Dust Monitoring

Leiths currently employ Vibrock, a specialist contractor to monitor the personal

dust exposure and personal noise exposure for the staff employed at all company

quarries. Vibrock or a similar specialist contractor will undertake personal dust

exposure and personal noise exposure monitoring throughout the operational life

of Dalwhinnie Quarry. As part of this monitoring exercise the level of fugitive dust

will be monitored at the site boundary with a dust pump placed at a boundary

location.

At all other Leiths operated quarries which extract similar rock, utilise identical

equipment, extraction techniques and mitigation measures as proposed for

Dalwhinnie Quarry all monitoring reports to date show the level of fugitive dust

generated is minimal.

4.2 Vehicle Emissions

The plant and vehicles to be used within Dalwhinnie Quarry are part of Leiths plant

fleet and are diesel powered. Improved fuel quality standards and European

vehicle emission limits have helped reduce the emissions from diesel engines as

fitted to HGVs and quarry plant.

Quarry plant is increasingly being fitted with diesel particulate filters and fuel

additive systems to aid the reduction in emissions. All Leiths operated plant is

maintained to a high standard in accordance with the manufactures

recommendations.

Plant Servicing and Inspection are detailed in Section 6.5.

5 Hydrology and Water Management

5.1 Rock Permeability

Dalwhinnie Quarry extracts a metamorphic psammitic rock from the Gaick

Psammite Formation. The permeability is principally controlled by the

discontinuities present in the rock. During extraction of rock by blasting the effect

of the explosives detonating opens joints and fractures within the rock structure,

these fractures preferentially follow the existing metamorphic structures in the

rock. These blast induced fractures locally increase the rock permeability.

5.2 Groundwater and Aquifer Potential

The water body in the existing quarry is primarily related to rainfall with water

trapped within the quarry void. The water level is between 390.5 – 391.0m AOD

with the adjacent ground to the South at a level of between 393 – 394m AOD.

The previous operator managed the water level by pumping, with the pump

discharging into an area to the East of the quarry bund. Over time the water level

has increased to the current level with no pumping taking place in the period the


Page 9 July 2018

quarry has not been operational, water outflow controlled by fractures within the

bedrock.

There are no records of the quarry previously encountering groundwater. No

water seeps were visible in the exposed areas of the quarry faces when the quarry

was previously operated.

Leiths excavated several trial pits using a large tracked excavator down to bedrock

as part of site investigation over the quarry extension footprint prior to designing

the quarry extension. These trial pits provided an assessment of bedrock depth

and the nature of the overburden.

None of these trial pits encountered surface or ground water.

The Hydrologeological map of Scotland indicates the rock in this area is a ‘low

productivity aquifer with small amounts of groundwater in the near surface

weathered zone and secondary fractures’.(1)

5.3 Surface Water

There are no watercourses within the quarry boundary or surface drainage ditches

adjacent to the quarry boundary. The River Truim lies in a valley to the East of

the quarry and the Allt Ant-Sluic tributary lies to the West of the quarry site. Both

watercourses are unaffected by the quarry.

Any rainwater which falls within the quarry footprint / catchment area either

disperses through the natural and blast induced fractures in the rock or is collected

within the quarry void. As the quarry develops the quarry floor will be profiled to

divert rainwater to the quarry sump. The quarry sump will be excavated to a

depth of between 3 and 5m below the quarry floor level. Initially the sump will

be approximately 10m by 8m in size. This will result in a capacity of between 240

and 400m3. As the footprint of the quarry develops the sump will be increased in

size to approximately 18m by 25m as shown on Phase 1 SWMP plan (Drawing No.

RG547/SWMP/F/02A), this will have a capacity of between 1350m3 and 2250m3.

The sump will be in use throughout the period the quarry is in operation, providing

a source of dust suppression water for rock processing and general quarry

operations, as discussed in Section 3.3 of the Ground Water and Surface Water

Management Plan.

Section 3.3 of the Surface Water Management Plan also discusses use of a float

switch controlled submersible pump in the quarry sump to manage water levels in

periods of heavy rainfall or low water use. When triggered the pump will discharge

to the shallow settlement ponds. The ponds will be retained during Phase 1 of the

quarry development. The ponds will be used in the initial dewatering of the

quarry, once dewatering is completed and quarry operations re-start the ponds

will only be in intermittent use. During normal quarry operations no water will be

present in the ponds, unless the pump in the quarry sump is triggered by the float

switch.


Page 10 July 2018

5.4 Water Discharge

No water will be discharged to neighbouring watercourses.

5.5 Water Abstraction

No water will be abstracted from neighbouring watercourses.

5.6 Domestic Water Supply and Waste Water

Dalwhinnie Quarry will not be connected to the mains supply, bottled water will

be used for drinking water.

Waste water will be treated by a septic tank system.

At present there is no infrastructure in place at Dalwhinnie Quarry, the previous

operator utilised a temporary/mobile cabin which is no longer on site. When

operations restart at the quarry a septic tank and associated discharge will be

installed. An infiltration test will be undertaken to ensure the ground conditions

are suitable and the tank will be installed to the manufacturers specification. Once

installed this will be registered with SEPA.

3. in the case of a tap or valve, fitted with a lock and locked shut when not in use; and

6.1.1 Fuel Tank Specification

The fuel tanks used on Leiths sites are modern double skinned tanks. At

Dalwhinnie the tank(s) and refuelling area will be located away from both the

operational area of the quarry and any vehicle routes. All tank connections are

secured when not in use.

The fuel storage tank(s), fuelling area and all fuel supply hoses are inspected on

a daily basis by the site manager or designated deputy as part of the site

inspection schedule.

A Copy of the Site Monitoring and Inspection Log (Form L.141a) is included in

Appendix A.


Page 13 July 2018

6.1.2 Oil Spill Resources

Oil spill kits and drip trays will be located adjacent to the fuel tank(s).

When the supplies in the oil spill kits are utilised these are replenished as soon as

possible to maintain the effectiveness of the oil spill kits.

6.2 Refuelling Procedures

6.2.1 Fuel Delivery

Deliveries of fuel are closely supervised; there is no unmanned filling of tanks.

The tanks, all connections and the integrity of the double skin bunds are inspected

both prior to and after refuelling has taken place.

The site manager or designated deputy will be available at all times during storage

tank refuelling.

6.2.2 Wheeled Plant Refuelling

The wheeled plant operated at Dalwhinnie quarry (loading shovels and dump-

trucks) are refuelled directly from the storage tank. Refuelling is done manually.

Refuelling hoses are fitted with an automatic cut-off. It is standard practice not

to ‘brim fill’ tanks to reduce risks of spillage.

The fuel tank is locked after use.

6.2.3 Tracked Plant / Mobile Plant Refuelling

Tracked Plant (typically 360° excavator, dozer, mobile crusher and screen units)

are normally refuelled using a portable bowser system. Each item of tracked

mobile plant is fitted with an electric fuel pump to allow insitu refuelling from the

portable bowser.

Refuelling from the bowser is manually controlled with the operator observing the

fuelling operation to ensure that overfilling cannot take place. It is standard

practice not to ‘brim fill’ tanks to reduce risks of spillage.

The portable bowser is secured when not in use.


Page 14 July 2018

6.2.4 Portable Bowser

The portable bowsers to be used at Dalwhinnie will meet the requirements of SSI

2017 No. 389. The Water Environment (Miscellaneous) (Scotland) Regulations

2017.

The requirements of SSI No 389 relevant to Dalwhinnie Quarry are:

(g) where a mobile bowser is used for storing oil:

(i) any tap or valve permanently fixed to the bowser through which oil can be discharged to the

open must be fitted with a lock and locked shut when not in use;

(ii) where oil is delivered through a flexible pipe which is permanently attached to the mobile

bowser:

1. the pipe must be fitted with a manually operated pump or a valve at the delivery end which

automatically closes when not in use;

2. the pump or valve must be provided with a lock and locked shut when not in use; and

3. the pipe must be fitted with a lockable valve at the end where it leaves the container and

must be locked shut when not in use; and

(i) any sight gauge must be secured to the mobile bowser and be fitted with a valve or tap which

must be locked in the shut position when not in use.”;

6.2.5 Leaks/Spillages While Fuelling

All plant fuelling is manually controlled both while using the fixed site tank and

using the portable bowser. Standard practice has the relevant plant operator

supervising the refuelling of his/her plant.

Drip Trays will be used when applicable during refuelling.

Any accidental spills related to refuelling operations will be of low volume and in

addition to the drip trays sufficient absorbent material is available to address these

spills. Oil spill equipment will be available both at the refuelling area and where

the mobile bowser is in use.

Any spillages will be reported and investigated in accordance with Leiths standard

procedures.

The pollution risks associated with refuelling are considered to be low.

Refuelling of the Dalwhinnie fuel tanks is also considered to be a low pollution risk

operation.


Page 15 July 2018

6.4 Oil /Grease / Coolant Storage

Any oil storage on site (engine oils, hydraulic oil, engine coolant and grease) will

be in a secure bunded container.

Any empty oil containers and waste oil containers will be clearly labelled and

stored in the same area. There will be a secure / oil tight storage bin for empty

grease cartridges and for used oil absorbent materials.

Used oil, fuel and oil filters will be transported to a Leiths workshop for disposal

by the plant maintenance fitters undertaking service work at Dalwhinnie Quarry.

6.5 Plant Maintenance

6.5.1 Plant Servicing and Inspection

All quarry plant and vehicles will be serviced and maintained by both Leiths and

the plant manufacturers. All plant is subject to daily inspections by the operators

to ensure there is no risk of oil or fuel spills during plant operation.

A Copy of the Mobile Plant Log Sheets are included in Appendix A.

A Copy of the Quarry Vehicle Daily Check Sheet (Form L.138) is included in

Appendix A.

Oil spill equipment will be available both at the refuelling area and where the

mobile bowser is in use. All quarry staff will be trained in the use of the oil spill

equipment.

6.5.2 Servicing

All plant operated by the company is maintained to a high standard by qualified

and experienced fitters. The maximum routine service frequency of 250 hours

between services exceeds the requirements of all the plant manufacturers. During

routine servicing of plant to be used at Dalwhinnie Quarry any potential sources

of leakage will be repaired as a matter of course.

6.5.3 Preventative Maintenance

Preventative maintenance on potential oil leaks is undertaken where plant

breakdown may cause pollution or will significantly affect production.

6.5.4 Contractors Vehicles/Plant

When contractors plant is working on any Leiths site this will have to comply with

the same inspection requirements and operational rules as Leiths owned/operated

plant. All plant from outside contractors will be inspected for leaks / potential

leaks by the quarry manager or designated deputy before being permitted to

operate at Dalwhinnie Quarry.


Page 16 July 2018

6.6 Oil Spill Procedures

6.6.1 Potential Oil Spill Scenarios – Quarry Operations

The main operations/incidents within a Quarry Area that could result in pollution

have been identified as follows:

Oil / Fuel Spills due to Plant Breakdown / Damage

Mechanical breakdown of plant does occur and can lead to minor oil or fuel

spillage.

As detailed above Leiths (Scotland) Ltd have a strictly maintained plant

maintenance schedule at all other sites which will also be used at Dalwhinnie

Quarry, this ensures that wherever possible potential breakdown scenarios are

addressed during routine maintenance.

Plant Fuel Systems

The fuel tanks on all plant are of a standard specification for the plant in use. The

fuel systems are inspected as part of the service schedule for each item of plant.

As a company Leiths (Scotland) Ltd have no records of any plant fuel tanks failing

and causing significant fuel spillages.

Hydraulic Hose Failure

Hydraulic Hose Failure or Leaks are identified as the most likely cause of oil spills

within a quarry. All experienced plant operators are aware of this and check their

equipment regularly.

Most modern plant has automatic shut-off valves if the hydraulic oil level or

pressure drops below a prescribed level. Sudden failure of hydraulic systems is

considered a rare occurrence, this will be immediately identified by a plant

operator. No unmanned plant is planned at Dalwhinnie Quarry.

Any leaking hydraulic hoses will be replaced as a matter of course during day to

day operations. The volume of oil involved is relatively low and standard practice

is to use absorbent material to treat any spillage.


Page 17 July 2018

6.7 Oil Spill Procedures

All spills or leaks (fuel, oil, hydraulic oil or coolant) will be treated as emergencies

and cleaned up immediately.

a) Stop the Flow of the Potential Contaminant

The first step in any attempt to minimize the damage due to a spill or leak is to

stop the flow of the potential contaminant.

b) Report the Spillage Report the spill and request assistance / resources as deemed necessary.

c) Contain the Spillage If the spill or leak cannot be stopped, containment measures, such as bunds, must

be constructed at once. For major spills the bucket of a wheeled shovel or digger

can be used to trap the contaminant. If the magnitude of a spill is such that

product is flowing across the ground, priority must be given to preventing the flow

of the spill toward the quarry sump; by methods such as placement of bunds in

advance of the spill.

d) Clean up the Spillage When the spill has been stopped the spilled material should be cleaned up using

a suitable absorbent material. Typically minor spills are absorbed by the upper

few inches of ground; this material should be dug up with hand shovels or quarry

plant and stored in impermeable containers in a suitable location until disposed of

by the correct manner.

e) Investigate / Rectify / Repair Source of Spillage

The source of the spillage should be investigated and all repairs necessary should

be carried out before the plant is returned to service. The plant should be moved

to a suitable area before any repairs are undertaken. The exception to this is

where moving an item of plant is likely to cause further leakage. All leaks should

be repaired prior to the plant being reused.

f) Complete Incident Report

An incident report will be completed for each spill recorded. This should contain

all relevant details referring to the incident. A copy should be retained in the site

office and a copy forwarded to the Plant Manager at Leiths (Scotland) Ltd so the

plant record can be updated.

g) Dispose of Contaminated Material. Storage and disposal of contaminated material will be in accordance with current

legislation and will be carried out in consultation with the Scottish Environment

Protection Agency (SEPA).

7 Waste and Recycling

7.1 Extractive Waste

Mineral waste produced during rock extraction, aggregate processing and site

preparation is covered by the Dalwhinnie Quarry Extractive Waste Management

Plan prepared in accordance with the Management of Extractive Waste (Scotland)

Regulations 2010.

7.2 Oil and Oil Contaminated Waste

All recovered oil, filters and oil contaminated absorbent material will be stored in

sealed secure containers before being transported offsite to Leiths workshops for

disposal.

The safe handling and disposal of recovered oil is governed by relevant sections

in the following legislation:

• The Environmental Protection Act 1990 • The Controlled Waste (Registration of Carriers and Seizure of Vehicles)

Regulations 1991 • Control of Pollution (Amendment) Act 1989

• The Waste Management Licensing (Scotland) Regulations 2011 • Special Waste Regulations 1996 (as amended)

If waste material is produced as a result of an accidental oil spill such as a burst

hydraulic or fuel pipe on plant the contaminated absorbent material will be

transported offsite for disposal.

Leiths (Scotland) Ltd are a registered waste carrier and as a company are

experienced in handling hazardous, non-hazardous and inert waste.

If the material is to be handled by contractors then the Leiths as the operator (to

reduce liabilities to a minimum) has to ensure that each contractor has the

relevant transportation registration and waste management licences, where

applicable.

1 Background

Many of the operations and activities in a hard rock quarry have the potential to

generate dust. Dust can be generated by the initial lifting of soil or overburden,

drilling and blasting, rock extraction, crushing and screening, haulage of products

off site and during site restoration.

The overburden at the quarry is a granular, free draining glacial material which

contains a high percentage of rock fragments. While no evidence of ground water

was identified within the overburden exposed in the trial pits, like all similar

materials it is naturally damp.

The site operation, dust control and monitoring procedures have been designed to

minimise and control emissions of dust in accordance with the best practice

published in:

• Process Guidance Note 3/8(12), Statutory Guidance for Quarry Processes.

Department of the Environment, Food and Rural Affairs (2012).

• Process Guidance Note 3/16(12), Statutory Guidance for Mobile Crushing

and Screening. Department of the Environment, Food and Rural Affairs

(2012).

• Planning Advice Note PAN 50, Controlling the Environmental Effects of

Surface Mineral Workings. The Scottish Office Development Department

(1996).

• Planning Advice Note PAN 50 Annex B, The Control of Dust at Surface

Mineral Workings. The Scottish Office Development Department (1998).

This ensures that the operations at Dalwhinnie Quarry do not constitute a dust

nuisance to neighbouring properties or the local environment.

2 Dust Management Strategy

The quarry manager or designated deputy is responsible for the control of dust

within Dalwhinnie Quarry. Site management will consider the advance weather

forecasts when assessing dust mitigation requirements.

It is the quarry manager or designated deputy’s responsibility to ensure that:

a) All Personnel working at the site are aware of their roles to minimise the

generation of dust.

b) Dust suppression equipment is in working order and available for use when

required.

c) Dust mitigation measures are deployed based on both visual observations

and prevailing weather conditions.

d) Records are maintained.



3 Dust Suppression Equipment

The dust suppression equipment to be used at Dalwhinnie Quarry will include:

• Water spray bars fitted to primary and tertiary crushers. Water is pumped

from the quarry sump but can also be sourced from an alternative supply

when required (eg water bowser).

• Water bowser, used to dampen internal roads, operating areas of quarry

floor, stockpiles and any other areas as required. The bowser is normally

filled from the quarry sump.

• Road Brush, the site manager or designated deputy will utilise a local hire

company to sweep and dampen the weighbridge area and quarry access

road as and when required.

• Drill Rig dust collector (see Section 5.3).

4 Dust Complaints

In the event of a complaint being received regarding nuisance dust, details of the

complaints will be logged and potential sources or occurrences onsite will be

investigated by the site manager. Records of all complaints received and remedial

actions undertaken will be held on site in the log book. This is in accordance with

the procedures in Leiths integrated management system.

Any dust complaints and the remedial action taken will be included in the annual

environmental (planning compliance) audit.

5 Dust Sources and Mitigation

Dalwhinnie Quarry has the potential to produce dust from a range of sources and

activities including:

5.1) Soil Handling / Site Preparation and Creation of Screening Bunds. 5.2) Drilling and Blasting. 5.3) Crushing and Screening of Aggregates.

5.4) Stockpiling and Loading of Aggregates. 5.5) Internal Vehicle Movement.

5.6) Offsite Transportation. 5.7) Restoration.

5.1 Soil Handling / Site Preparation and Creation of Screening Bunds.

Potential Impacts

Soil and overburden are normally stripped during the Spring and Summer months

when the weather is drier which is more suitable for soil handling. Dry weather /

dry soil will increase the risk of dust generation. Moving and placing the soil and

overburden in screening bunds has the potential to give rise to dust.

Mitigation

At Dalwhinnie Quarry the material will be moved a short distance to the site

boundary to form the landscaped screening bunds. If the soil is stripped from the



site in periods of windy and dry weather there will be facilities to dampen the

exposed soil and screening bunds using the water bowser. Where possible the

‘turf’ of the existing vegetation will be placed on the outer surface of the bunds to

promote re-vegetation. The screening bunds will also be monitored to assess if

planting is required.

Using the proposed mitigation, the potential for dust emission during soil stripping

and bund creation is assessed as low



5.2 Drilling and Blasting

Potential Impacts

The rock is extracted from the quarry by controlled blasting. Each blast is

designed to provide the optimum degree of rock fragmentation. The rock face is

profiled by laser profiler and the blast holes are set-out to suit the blast design.

The blast holes are drilled to a pre-determined depth before the explosives are

loaded and the blast is fired to dislodge the rock.

Both drilling and blasting have a high potential for dust generation.

Mitigation

All drilling rigs are fitted with dust extraction equipment. Dust collection during

drilling is mandatory under the COSHH Regulations(1). With the use of dust

extraction equipment little fugitive dust is produced during rock drilling.

A small quantity of dust will inevitably be produced as a blast is fired, this is

primarily larger sized particles and by its nature each blast is a short-term event.

Blasting will be undertaken infrequently during the year. Paragraph 15 of PAN 50

Annex B highlights ‘Large dust particles (greater than 30µm) make up the greatest

proportion of dust emitted from mineral workings and will largely deposit within 100m of

sources’. Blasting takes place below the natural ground level within the quarry and

any dust produced by blasting will be contained within the quarry void.

With the mitigation in place which is required by legislative controls, the potential

for dust emission related to drilling and blasting is low. The DOE commissioned

study on which PAN 50 Annex B is based confirms ‘properly designed and controlled

blasts have limited potential to produce dust emission’ (2).

& Partners, 1995.



5.3 Crushing and Screening

5.3.1 Primary Crushing of Aggregates

Potential Impacts

Primary crushing is undertaken directly from the blast pile at the quarry face. The

rock is fed into a tracked jaw crusher by 360° excavator at a controlled rate. The

output from the crusher is either transported from the crusher for further

processing by wheeled loading shovel or by a separate conveyor. Depending on

the location in the quarry the primary crusher may, at times, also feed directly

into a tertiary crusher.

All crushing of rock has the potential to generate dust.

Mitigation

The crusher is positioned to screen the operation as far as possible from the

prevailing wind and crushing will always take place below the natural ground level

within the quarry. The best practice used includes using reduced drop heights

from conveyors and using stockpiles of crushed material to provide further

screening.

Primary crushing is undertaken using crushers from Leiths mobile plant fleet. All

Leiths primary crushers are fitted with dust suppression equipment and all

conveyors have wind boards and scrapers. The operation of crushers and use of

dust suppression is regulated by the mobile plant PPC permit

Using recognised best practice and the mitigation available, the dust emission

from primary crushing is minimised.



5.3.2 Tertiary Crushing and Screening of Aggregates.

Potential Impacts

Tertiary crushing is undertaken within the quarry void, normally on the quarry

floor. Rock is fed into the tertiary crusher by either a 360° excavator or a wheeled

loading shovel at a controlled rate. For efficiency the output conveyor from the

tertiary crusher usually directly feeds screening plant to produce graded

aggregates. The configuration of the crusher and screens depends on the product

specification required.

Both tertiary crushing and screening of rock has the potential to generate dust.

Mitigation

The crusher and screens are located within the quarry void and are positioned to

screen the operation from wind. All conveyors are fitted with wind boards and

scrapers. Recognised best practice includes using reduced drop heights from

conveyors and using stockpiles to provide further wind screening. The tertiary

crushers and screens to be used are fitted with dust suppression equipment. The

operation of crushers and screens along with the use of dust suppression is

regulated by the mobile plant PPC permit.

The location of the crusher and screens within the quarry void in a sheltered

location, in conjunction with recognised best practice and the mitigation available

ensures the dust emission from tertiary crushing and screening is low.



5.3.3 Emissions Monitoring – Crushing and Screening Plant

Emissions monitoring from the crushing and screening plant is undertaken in

accordance with the conditions in the mobile plant PPC permit.

When required the dust suppression systems are used to minimise emissions from

the crushing and screening plant. If the dust suppression equipment fails during

operation, crushing and screening will be stopped until the dust suppression

equipment is repaired.

A visual assessment of emissions to air is undertaken a minimum of three times

a day when any crushing and screening plant is operating. The initial observation

is undertaken at start-up and all observations are undertaken from within the

quarry boundary. All emissions to air from the Permitted Installation shall be free

from visible particulates beyond the Site Boundary.

All observations are recorded in the site log book and each record includes:

a. Name and location of the observer.

b. Date and time of assessment. c. Wind and weather conditions. d. Duration and the results of the assessment.

The site log book records are retained on site for both internal and SEPA audits.

Any incidents are recorded in the site log and are reported to SEPA using the

procedures in the PPC permit. The frequency of visual assessments will be increased during periods of dry and

windy weather.

Dust monitoring will be included in the annual environmental (planning compliance) report.



5.4 Stockpiling and Loading of Aggregates.

Potential Impacts

All aggregate stockpiles will be located within the quarry void. There is the

potential for wind-blow from the surface of stockpiles which can give rise to low

to moderate levels of dust emission. Aggregate is loaded from stockpiles into

customer vehicles. Any operation which picks up or moves aggregate has the

potential to generate dust. Where screened or graded aggregate is being handled

the potential of dust generation decreases with larger sized aggregates.

Mitigation

The stockpiles are located within the quarry void where they are sheltered from

the effects of wind. Best practice will be followed on aggregate loading with

aggregate taken from the leeward side of stockpiles, using the stockpile to shield

the loading shovel from the effects of wind and by utilising reduced drop heights

when moving material. Stockpiles of fine grained material will be sprayed, as

required, using a water bowser to minimise the risk of dust becoming airborne.

With the location of the stockpiles in a sheltered location in conjunction with

recognised best practice and the mitigation used, the potential for dust emission

from stockpiles and loading from stockpiles is minimal.

5.5 Internal Vehicle Movement.

Potential Impacts

The transportation of material within the quarry can cause dust emission from

vehicle movement related to speed, dust from transported materials and from

dirt/dust on internal roadways.

Mitigation

All vehicles used for the movement of materials within the site are equipped with

exhausts pointing away from the ground and all heavy plant is fitted with radiator

fan deflector plates, to reduce the risk of dust being disturbed by the operation of

quarry plant.

Within the quarry, temporary haul roads and the quarry floor will be surfaced using

crushed rock to promote free drainage of the operating surface. The temporary

haul roads and ramps along with the operating area of the quarry floor will be

maintained to a high standard to minimise unnecessary wear on plant and to

reduce the dust risk. A bowser will be utilised to dampen the quarry floor and

temporary haul roads during periods of dry and windy weather.

With the mitigation in place the risk of dust generation from internal transport of

materials is low.



5.6 Offsite Transportation of Materials.

Potential Impacts

The transport of aggregates off-site may cause dust from vehicle movements

related to vehicle speed, dirt on roads, dirt on vehicles or dust from transported

aggregate.

Mitigation

Aggregate will be loaded directly to road vehicles from stockpiles in the main

quarry area. The internal road will be maintained to a high standard with a free

draining crushed rock surface. The quarry floor and the stockpiling areas will also

be surfaced with crushed rock. The crushed rock surface ensures a free draining

substrate, this also helps minimise the risk of contamination of the aggregate

stockpiles from dirt or mud.

The site entrance, weighbridge and access road will be maintained to a high

standard with a road sweeper used to clean and dampen the road surface when

required.

Dust prone aggregates will be sheeted on dispatch as is recognised best practice.

The site will have an internal speed limit of 10mph which also helps reduce the

risk of vehicles causing excess dust.

With the mitigation measures in place within the quarry there is a low risk of dust

generation from offsite transport of materials.

5.7 Restoration

Potential Impacts

During restoration of the site the soil and overburden previously stripped from the

site will be moved and used for restoration. All movement of soil has a potential

for dust generation in periods of dry weather.

Mitigation

If the soil is moved in periods of dry weather there are the facilities to dampen

the exposed soil. Where possible any ‘turf’ of the existing vegetation will be used

to promote re-vegetation. The restoration will be monitored to assess if planting

is required. If planting is required locally sourced seed of local provenance will be

used.
