1 INTRODUCTION

Site Environmental and Remediation Services (SERS) have been commissioned by the City of Subiaco

(the client) to prepare a Dust and Air Quality Management Plan (DAQMP) for the asbestos removal works

proposed at Lords Recreation Facility (the Site) and to monitor the asbestos removal works. Asbestos

removal work has been commissioned following the identification of asbestos at various locations within

the existing building, external walls, roof and roof space. Lords Recreation Centre has been closed to

the general public since March 2014, when the council of the City of Subiaco voted unanimously to

commit funds to remove all asbestos and replace the roof at Lords recreation centre.

The proposed works at the site will remove all of the asbestos which has been identified as a result of

the laboratory testing carried out in March 2014. It will also involve a thorough detail of the Centre to

clean-up all internal dust.

The objectives of the DAQMP are:

To ensure that errant dust is not generated during the remediation/ removal works;

To minimise the dust generation as best as practical in accordance with relevant legislation and

guidelines; and

To ensure that air quality complies with regulatory guidelines set for the protection of human

health.

This DAQMP specifically addresses:

Location of air quality monitoring sites;

Measures and practices to minimise the generation of dust;

Monitoring program for fine particulates and fibres;

Relevant regulatory guidelines and compliance criteria; and

Nomination of action levels and contingency measures in the event that air quality is likely to

exceed (or approach) relevant compliance criteria.

Section 2 of the report outlines air quality issues and the potential sources of dust during the proposed

site works. Section 3 details the proposed air quality management/ mitigation procedures and the air

quality monitoring programme is outlined in Section 4. Contingency response is provided in Section 5.


01043/HS/DAQMP/060614Rev2 2

2 AIR QUALITY ISSUES

2.1 Overview

Dust is considered to be any particle suspended within the atmosphere. Particles can range in size from

as small as a few nanometres to 100 microns (μm) and can become airborne through the action of wind

turbulence, by mechanical disturbance of fine materials or through the release of particulate-rich gaseous

emissions.

Airborne asbestos fibres means any fibres of asbestos small enough to be made airborne. For the

purposes of monitoring airborne asbestos fibres, only those fibres less than 3 μm in width, greater than

5 μm long and greater than 3 to 1 length to width ratio are counted.

Dust can be generated from a variety of source, such as the uplift of windblown material, the movement

of machinery or the excavation of a site. It is the objective of the dust management procedures that dust

generated on-site is kept to a minimum and any dust does not cross the site boundary.

Dust is measured using a variety of methods, the most common being Total Suspended Particulates

(TSP), which measures up to 50μm in size, and PM10 or PM2.5 (particulate matter less than 10μm or

2.5μm in size, respectively) (DEC 2011).

2.1.1 Impacts of Dust on Human Health

The impacts of dust are influenced by particle size, chemical composition and concentration. Particles

with a diameter less than 50µm (usually referred to as TSP) are typically associated with adverse

aesthetic effects rather than health effects. This is because they are trapped in the upper respiratory tract

(just behind the nose and mouth) when inhaled. These larger particles are called inhalable particles and

comprise visible dust following settling on surfaces, causing soiling and discolouration. They may,

however, be associated with irritation of the mucosal membranes (eyes, nose and throat) and if

contaminated may pose an increased health risk through ingestion.

Human health effects of dust tend to be associated with particles with a diameter of 10µm or less (referred

to as PM10). These smaller particles tend to remain suspended in the air for longer periods and can

penetrate into the lungs. PM10 fraction (coarse fraction) is termed ‘thoracic particles’ of ‘inhalable dust’.

These particles are inhaled into the upper part of the airways and lung.

Dust particles with a diameter of 2.5 µm (referred to as PM2.5) are inhaled more deeply and lodge in the

gas exchange region (alveolar region) of the human lung and are termed ‘respirable dust’. If

contaminated, these fine particles may pose a further health risk through absorption of the chemicals on

the particles in the blood stream.

Sensitive groups such as people with lung or heart diseases, children and older adults are the most likely

to be affected by particle pollution exposure. However, even healthy people may experience temporary

symptoms from exposure to elevated levels of particle pollution.


01043/HS/DAQMP/060614Rev2 3

2.1.2 Impacts of Airborne Asbestos Fibres on Human Health

Asbestos can cause health effects if fibres are breathed into the lungs. Most fibres are removed from the lungs by the body's natural defences (eg. by being coughed up and then swallowed), however some fibres can remain in the lungs.

The possible health effects of asbestos are:

Asbestosis (progressive and irreversible scarring of lung tissue that impairs breathing)

Lung cancer

Mesothelioma (a cancer of the linings around the lungs and abdomen)

Non-cancerous diseases that affect the linings around the lungs and abdomen (commonly called 'benign pleural diseases')

These diseases can sometimes take up to 50 years to develop. There may be some treatments for asbestos related diseases, but there are currently no known cures.

2.1.3 Potential for Dust Particle / Fibre Emissions

The asbestos removal works involve the removal of all materials which contains asbestos, which were

previously identified during the hazardous material survey. The works are to commence with a full detail

of the building internally, in order to remove all of the dust particles/ debris which has been identified. All

material which is identified as containing asbestos will then be removed from the site and further residual

dust generated through the removal works shall be cleaned and the building certified as clean and clear.

These works have the potential to generate airborne dust particles/ fibres.

When taking into account the proposed site activities, there is the potential for the removal works to

generate dust particles /fibres if it is not undertaken in a controlled and responsible fashion. Typically the

works are expected to involve the vacuuming of internal surfaces, the movement of trucks, the loading /

unloading of materials and the dislodging of asbestos sheeting. Dust particles /fibres could be generated

as a consequence of any of these activities and the severity of dust/fibre generation will be a function of

the magnitude of removal works, prevailing weather conditions and the presence of fine particles. High

speed winds may exacerbate the potential for dust generation.

2.2 Site Location and Surrounding Land Uses

The entire site area equates to approximately 18,300m2 (1.83ha) which includes the car parking area.

The footprint of the Recreation Centre building is estimated to be in the region of 9000m2. The site is

zoned in the City of Subiaco Local Planning Scheme for Commercial/Residential uses, this use extends

along Hay Street road frontage. The area to the north and northeast is zoned for “Residential (R60)”, with

Hay Street (immediately south of the site) zoned as “Other Regional Road”. The area to the south of Hay

Street is zoned for Residential use, at various densities.

The land uses in the immediate vicinity of the site are predominantly residential, with a limited volume of

commercial buildings situated nearby on Hay Street.

The existing surrounding land uses can be summarised as follows:


01043/HS/DAQMP/060614Rev2 4

North and Northeast

This land has been development for residential purposes and contains established town houses

and apartment developments. This land is populated with many residences in close proximity to

the site.

East

The land to the west of the site (known as Viridian China Green) falls within Metropolitan

Redevelopment Authority area (Subi Centro) and is currently being developed. This land has

been prepared for development with road infrastructure clearly visible. Previous buildings which

occupied this land have been demolished and debris removed from site, leaving it vacant. It is

noted that there is the potential for errant dust uplift to be generated on this land that could impact

the site when the wind originates from the east.

South

Hay Street forms the southern boundary of the site, this is identified as an “Other Regional Road”

in the City of Subiaco Local Planning Scheme. Beyond Hay Street established residential

properties are present.

West

The pocket of land to the west of the site and east of Tighe Street contains established residential

properties, these are located in close proximity to the site, the closest being separated from the

site by the residential car park area. To the west of Tighe Street mixed commercial properties line

Hay Street.

The land immediately to the east (Viridian China Green) is currently undergoing redevelopment into

apartment blocks (Please see Figure 2 – Site Location). This land has been stripped of surface

vegetation and roads have been created to service this development. This land has the potential to

generate dust that could impact the site during easterly winds. The development of this site has been

commenced in the past 6 months and will continue for the duration of proposed works. It must also be

considered that workers on this site may be considered as potential receptors of environmental impacts

from the removal works.

2.3 Seasonal Wind Strength and Direction

It is important to establish prevailing wind conditions which affect the site as they have the potential to

impact the level of dust uplift across the site and the direction which any errant dust is carried.

The wind roses shown (Figure 1 – Wind Roses (Data from Perth Airport)) reflect recordings from the

Perth Airport weather station. It is not anticipated that the wind condition of the site will significantly differ

from those recorded at Perth Airport.

Spring mornings are calm approximately 13% of the time. Approximately 22% of the time, wind emanates

from the east, with winds from the northeast and south equating to approximately 12% each. It is noted

that winds rarely exceed 30 km/h, and if so are dominantly from the east.


01043/HS/DAQMP/060614Rev2 5

Winds on spring afternoons come from the southwest approximately 35% of the time, and from the west

approximately 30% of the time, most commonly reaching speeds between 20 and 30 km/h. They are

calm only 3% of the time.

Summer mornings show a pronounced dominance of winds from the east, occurring approximately 36%

of the time. As in spring, winds come from the northeast and south approximately 11% and 15% of the

time respectively. Conditions are calm only 7% of the time.

Summer afternoons show a more pronounced dominance of wind from the southwest, occurring 40% of

the time, and westerlies lessening to 25%. Dominant wind strength remains between 20 and 30 km/h.

Calm conditions occur only 2% of the time.

Autumn mornings emulate spring mornings with greater prevalence of easterlies, approximately 30% of

the time. North-easterlies occur approximately 20% of the time, and 18% of the time conditions are calm.

Autumn afternoons show equal influence of south-westerlies and westerly winds occurring approximately

22% of the time each, averaging speeds of 10-30 km/h. Easterlies also take increasing precedence

occurring approximately 15% of the time. Only 5% of conditions are calm.

Winter mornings (which is when this project is to be undertaken) show weak winds from the northeast

dominating at approximately 25%, with 15% of winds from the north and 15% from the east. Wind speeds

are predominantly up to 20 km/h and are calm for 22% of the time.

Winter afternoons are calm 8% of the time, with 20% of the wind from the west, 15% from the southwest

and 12% from the northwest. Winds are commonly up to 20 km/h.

NB. Wind directions are divided into eight compass directions. The circles around the image represent the various

percentages of occurrence of the winds. For example, if the branch to the west just reaches the 10% ring it means

a frequency of 10% blowing from that direction. The scale factor can be ignored when interpreting these wind roses.

An observed wind speed which falls precisely on the boundary between two divisions will be included in the lower

range (eg 10km/h is included in the 1-10 km/h range).

Calm has no direction. An asterisk (*) indicate that calm is less than 1%.

As mentioned, the project is proposed to commence in June 2014 and continue for approximately three

(3) months, signifying that the work will take place during the winter months. During this period the

morning winds originate from the north, northeast or east 55% of the time, with the wind being recorded

as calm 22% of the time.

Winter afternoons are recorded as calm just 8% of the time, it is expected that the wind will originate from

the west, northwest or southwest 47% of the time, increasing the potential for errant to impact of

properties to the east of the site.

The works schedule through the winter months will result in the work taking place during the period of

highest rainfall, which is noted to dampen down materials which could otherwise be subject to windblown

dust uplift.


01043/HS/DAQMP/060614Rev2 8

3 AIR QUALITY MANAGEMENT

Dust and other air pollutants can arise from a range of natural and man-made sources causing various

acute and chronic health effects, as well as nuisance and visibility impacts. Sources relevant to activities

on-site are high-lighted in bold;

Wind borne dust from exposed surfaces such as cleared land and construction sites;

Wind borne dust resulting from remediation sites;

Wind-borne dust from stockpiles of material such as sand, soils, mineral ores, sawdust, coal and

fertiliser;

Vehicle movements on paved and unpaved roads;

Mines and quarries;

Agriculture and forestry activities;

Road works and road construction;

Demolition and construction sites;

Municipal landfills and other waste handling facilities;

Explosive blasting of rock;

Abrasive blasting;

Handling, crushing, grinding/pulverising, screening of mineral ores and other solid matter;

Numerous industrial operations, including grain and mineral ore transfer and storage, timber mills,

stone masonry, mineral processing, cement handling and batching, and fertiliser storage and

processing.

It is the objective of the dust and air quality management measures to ensure the protection of human

health and minimisation of adverse impacts on environmental health and amenity by ensuring that dust

arising from the remediation works at the site.

During removal works on site all appropriate PPE and RPE must be worn at all times, please refer to the

contractors approved Site Management Plan for further details.

3.1 Dust Particle and Fibre Release Control Measures

During the removal works the primary function of the control measures are to avoid the generation of

dust and fibres in keeping with industry standards and legislation. There are several measures which will

be carried out at various stages of the project dependent on the established risk factor. These measures

have been identified and risk assessed in Table 3-1.

High-speed abrasive power or pneumatic tools such as angle grinders, sanders, saws and high speed

drills must never be used directly on asbestos containing materials for health and safety reasons.


01043/HS/DAQMP/060614Rev2 9

3.1.1 Cleaning and Detailing of surfaces

From an indicative asbestos testing regime it has been assessed that asbestos free fibre exists on

surfaces throughout the recreation centre. In order to decontaminate the building it is required that all

surfaces be wet wiped and/or vacuumed to remove all dust and grime. All surfaces for the purposes of

asbestos clearance certification must be free of dust and grime.

Vacuums used shall comply with AS/NZ 60335.2.69, be Class H rated and HEPA filters shall comply with

AS 4260-1997. When wet wiping, procedures to ensure continued use of the same rag / cloth causing

potential cross contamination is to be formulated and adhered to by the contractor.

Detailing and cleaning shall be executed in a sequential manner as to minimise potential for cross

contamination of areas.

3.1.2 Removal of Asbestos Roof and Wall Sheeting

Prior to the removal of any Asbestos Cement (AC) sheeting (the roof sheeting and wall sheeting for

example), a bonding solution (i.e. PVA) will be applied to both sides of all sheets. The application of such

will not be of sufficient force that droplets might generate dust/fibres when they hit the surface of the

material. Sufficient time will be allowed for the bonding solution to dry on the roof sheets to eliminate any

potential slip hazard.

During the removal of AC sheeting, the tools used for the works will be restricted to hand tools, no

mechanical tools will be permitted to carry out any removal works. Hand held electric fasteners to remove

screws from asbestos sheeting is permissible as is standard industry practice.

All sheeting must be stacked and wrapped (see Section below for wrapping requirements) before they

are lowered to appropriate levels so that they do not break and generate dust/ fibres.

3.1.3 Disposal of asbestos from site

All asbestos waste shall be placed immediately into 0.2mm heavy duty plastic bags and double-bagged

or wrapped in 0.2mm heavy duty plastic and double-wrapped, goose necked/ taped and sealed prior to

loading into transport vessels. All bags and plastic containing asbestos waste are to be clearly labelled

as “CAUTION – ASBESTOS WASTE”.

All asbestos cement roof and wall sheets are to be wrapped in 0.2mm heavy duty plastic prior to lowering

to appropriate levels. All asbestos waste is to be transported in suitable vessels and double-wrapped/

double- bagged in 0.2mm heavy duty plastic with all loads further covered for transport.

All asbestos waste shall be disposed of at a suitably landfill facility as licensed by the Department of

Environmental Regulation (DER). Waste documentation shall be forwarded to the superintendent for

verification and waste tracking purposes.

3.2.4 Fencing and scaffold installations

All site fencing and scaffold erected onsite shall be covered with a shade cloth with sufficient density to

act as a dust screen for dust particles. Fencing and scaffold used onsite shall be of sufficient strength to

hold the weight of cloth and bear any associated wind loading. The structural integrity of any scaffold

being used as access or edge protection must be maintained throughout works.

4 AIR QUALITY MONITORING

An air monitoring programme will be in effect throughout the removal work at the site, the monitoring

locations and sampling methods have been chosen to ensure a robust assessment of dust particulate

and fibre concentrations at the boundary of the site and in the immediate work area. The monitoring

measures are in line with standards and legislative requirements.

The objective of the air quality monitoring programme is to ensure the dust and fibre management

measures are effective in preventing dust and fibre generation; and in doing so preventing exposure of

on-site workers and off-site residents to possibly harmful levels of airborne contaminants.

4.1 Baseline Monitoring

Baseline air quality monitoring (as per Section 4.2 and 4.3) will be carried out at the site prior to the

works commencing. Monitoring will be conducted as per the locations provided for in Figure 3 –

Monitoring Locations. The observed background levels will be used as the benchmark for assessing

any degradation of air quality as a result of the removal works. Weather conditions will also be noted

during this observation period.

No activities will be allowed at the site at the time of baseline monitoring that have the potential to

influence the background air quality readings (such as vehicle movement) and that conditions are

representative of normal background..

4.2 PM10 and PM2.5 Dust Monitoring

Monitoring for dust will be carried out on a real-time 24/7 basis during the removal project. Three (3no.)

monitors will be located on site at predetermined locations during the removal work, with monitor

locations varying throughout works to reflect the location of site work. Each monitor will record real time

data. In addition real time alarms via email / SMS shall be sent to nominated personnel when

predetermined threshold levels are exceeded.

The nominated warning threshold on the monitors will be set at 50μm/m3 for PM2.5 averaged over a 5

minute period upon the commencement of the removal works. This will be the assigned Work Stop Level

and this level will be reviewed periodically at the discretion of SERS. When the nominated level is

exceeded, works shall cease immediately onsite and an investigation into the potential cause of the

exceedance shall commence. Works will not recommence until the environmental consultant is satisfied

that works are being undertaken in a controlled manner.

Internal monitoring locations shall be designed to monitor asbestos abatement works in real time to

measure the effectiveness of the contractor’s dust (fibre) control measures in the execution of the works.

External monitors will be situated to measure dust generation in real time to the closest sensitive receptor

to the site, being the residences on Price Street.


01043/HS/DAQMP/060614Rev2 13

4.2.1 Guidelines

The National Environment Protection Measure (NEPM) standard for particles 10 microns and under

(PM10) is a maximum (ambient) concentration of 50µg/m3 averaged over one calendar day (midnight to

midnight). As per the NEPM, this standard is not to be exceeded more than 5 days per year. At the time

of writing this DAQMP, the Australian Government has issued an intention to varying the National

Environment Protection (Ambient Air Quality) Measure.

4.2.2 Methodology

SERS are equipped with an array of dust monitors and undertake dust monitoring for a wide range of

clients in Western Australia since 2008. SERS utilise the DustTrak DRX Aerosol Monitor 8533 as our

preferred monitoring unit because they can simultaneously measure both mass and size fraction of dust

particles. The DustTrak DRX monitor is a battery operated, data-logging, light-scattering laser

photometer that gives real-time aerosol mass readings. It uses a sheath air system that isolates the

aerosol in the optics chamber to keep the optics clean for improved reliability. All units are routinely

calibrated and maintained by SERS.

Dust monitoring locations (as per Figure 3 – Monitoring Locations) were chosen so that a true

representation of dust generation from site activity could be established in line with the DER guideline A

guideline for managing the impacts of dust and contaminants from land development site, contaminated

sites remediation and other related activities, January 2011. Prevailing wind and site conditions at the

time were factored into the monitoring program design

4.3 Respirable Fibre Monitoring

A total of up to twelve (12no.) boundary locations surrounding the site and up to ten (10no.) immediate

control locations surrounding any work area are intended to be utilised during the works. The positioning

of the immediate control locations will be determined on a day to day basis focusing on areas where

works will be undertaken.

Boundary monitoring locations have been chosen to provide a level of confidence on the abatement

measures being undertaken as a whole within the immediate work area. Figure 3 – Monitoring

Locations indicates the location of the boundary monitoring points.

Air quality monitoring will take place on a daily basis at the site, monitoring will commence before work

commences on site and continue until after removal work has finished. Monitoring sites will be located

away from any large structures or vegetation to avoid areas of poor air mixing and away from plant and

infrastructure such as air conditioners or exhausts to avoid areas of excessive air mixing and

transmission.

Static samples will be collected under the following conditions:

Field personnel are required to wear Personal Protective Equipment (Hooded Coverall, P2 mask,

boots and hard hat)

Each pump is to be calibrated against a primary source such as a field rotameter.

Flow rates are to be recorded before and after sampling


01043/HS/DAQMP/060614Rev2 14

Samples are to be taken between one and two metres above ground level

The sampling time is between approximately four and eight hours

The flow rate is approximately 2L/m-1

The sampling volume should be approximately 500 L to 1,000 L

All sampling regimes and laboratory processes are to be compliant with LABORATORY MANAGEMENT

SYSTEM: POLICIES AND PROCEDURES (SERS, 2011), which is a NATA certified laboratory.

All monitoring and clearance inspections are to be undertaken by licenced Class A Asbestos Assessors

in the employment of SERS, as per the requirements outlined within How to Safely Remove Asbestos

Code of Practice (Safe Work Australia Dec 2011).

All fibre counting of cassettes/slides will be duly deemed competent by the National Asbestos Program

(NAP) and in the employment of SERS. All counters are NATA approved signatories.

The sample cassettes are to be capped and delivered to the SERS NATA accredited laboratory for the

analysis of respirable fibres in accordance with the relevant provisions of Guidance Note on the

Membrane Filter Method for Estimating Airborne Asbestos Fibres 2nd Edition [NOHSC:3003(2005)]

Canberra. Due to the limitations of the analytical method, fibre concentrations are reported to the nearest

one hundredth of a fibre per mL and the limit of detection is one hundredth of a fibre per mL. Hence the

only possible results are <0.01, 0.01, 0.02, 0.03 fibres per mL and so on.

Sample analysis results are to be compared to the Control Level of 0.01 respirable fibres per mL. Control

measures are to be assessed if any sample returned a value of 0.01 fibres per mL. Work is to be stopped

and the source identified upon receipt of any sample analysis result of above 0.02 respirable fibres per

mL. This is summarised in Table 4-1.

Results are to be made available to the client and all working parties and will be in a format that is in

compliance with all legislative requirements.

Results from the previous day’s monitoring will be presented in a report that will be made available to the

client and contractors the following morning.

All respirable fibre monitoring points will immediately be capped and delivered to the SERS NATA

accredited laboratory for the analysis of respirable fibres in accordance with the relevant provisions of

Guidance Note on the Membrane Filter Method for Estimating Airborne Asbestos Fibres 2nd Edition

[NOHSC:3003(2005)] Canberra.

Sample analysis results are to be compared to the Control Level of 0.01 respirable fibres per mL. Control

measures are to be assessed if any sample returned a value of 0.01 fibres per mL or above, work is not

to be recommenced until the source of the fibre is identified and rectified.

5 CONTINGENCY RESPONSE

Should air quality monitoring show that dust and airborne contaminant emissions exceed the assigned

threshold levels, dust management practices will be immediately reviewed and corrective actions taken

to improve air quality.

5.1 Alarms and Reports

Air quality monitoring will take place for dust and fibres while removal works are taking place at the site.

If an exceedance of the assigned level is recorded on any monitor, work shall immediately stop at the

site and actions to rectify the situation must be taken. Exceedances shall be recorded by means of a text

alarm immediately to the assigned personnel and SERS. All exceedances shall be documented and

notified to the City of Subiaco.

The laboratory reports for respirable fibre monitoring will be forwarded to the Client on the same working

day and information passed to the contractor on the effectiveness of the management measures at pre-

start meetings and tool box talks.

Consolidated reports for dust monitoring will be made available weekly to the Client.

5.2 Corrective Actions during Removal Works

If the Work Stoppage Level is exceeded, all removal works deemed to be the source of emissions will

cease until monitored levels fall below the assigned threshold level.

The corrective actions for alarms will typically comprise the following sequence of actions:

Immediate cessation of work onsite;

Review of wind speed and direction to identify the potential dust source;

Review of contractors methods of removal;

Checking all trucks and machinery are free of dust;

Increase dust suppression measures (such as addition PVA spray or dampening of material) to

prevent further dust uplift; and

Ensure the loading and cleaning area is free from dust and debris.

5.3 Public Queries

Any queries received will be taken and addressed immediately by the Communications Officer at the City

of Subiaco.

6.0 VALIDATION OF THE WORKS

Independent verification of the asbestos removal works will be conducted by the superintendent’s

environmental representative, SERS. Verification of the effectiveness of the asbestos removal works will

be undertaken by a combination of visual inspection, dust sampling and air monitoring. The criteria for

gaining an asbestos clearance for the site are outlined below;

Validation Method Pass Criteria

Visual inspection Absence of visual asbestos containing material

or general dust and debris.

Air monitoring < 0.01 f/mL

Sampling (bulk and dust sampling) No Asbestos Detected (NAD) by an

independent NATA certified laboratory

Upon the decision of the Environmental Consultant, where a clearance inspection and test is not

achieved for an area, the contractor must remedy the area and the clearance process will be repeated.

Repetition of the process will occur until clearances of the area are attained as a part of the contracted

terms.

Where an asbestos clearance is sought for a nominated area and given, the area must be sufficiently

isolated from any other asbestos removal activity. Where cross contamination of asbestos in the opinion

of the environmental consultant may have occurred into a previously cleared area, validation sampling

and inspection will be repeated at the contractor’s expense.
