Executive Summary: Air Quality in Our Area

Air Quality in the Harrogate district

Air pollution is associated with a number of adverse health impacts. It is recognised

as a contributing factor in the onset of heart disease and cancer. Additionally, air

pollution particularly affects the most vulnerable in society: children and older people,

and those with heart and lung conditions. There is also often a strong correlation with

equalities issues, because areas with poor air quality are also often the less affluent

areas1,2.

The annual health cost to society of the impacts of particulate matter alone in the UK

is estimated to be around £16 billion3.

Harrogate Borough Council (HBC) has declared four air quality management areas

(AQMA’s) for breaches of the annual mean objective for nitrogen dioxide (NO2).

These were declared at Bond End, Knaresborough and Low and High Skellgate,

Ripon in 2010, and York Place, Knaresborough and Wetherby Road, Harrogate in

2017. There are no other pollutants or areas of concern across the district.

In 2019, there were no exceedances of the annual mean objective in three out of the

four AQMA’s. Within the Knaresborough AQMA No. 1 (referred to as the Bond End,

Knaresborough AQMA) there was one exceedance of the air quality objective, with

significant decreases in other locations within the Bond End, Knaresborough AQMA.

This is following major junction works within the Bond End, Knaresborough AQMA,

which were completed in November 2018. The general trend for the district is that

NO2 levels are decreasing.

Actions to Improve Air Quality

Over the last year we have continued to implement the actions within the action plan.

The sustainable transport team at HBC have been moving forward with the measures

proposed within the low emissions strategy. The air quality steering group has drawn

up ideas for engineering solutions for Ripon, and these ideas need to be investigated

further by NYCC. We have been working with the Public Health team at NYCC to

1 Environmental equity, air quality, socioeconomic status and respiratory health, 2010 2 Air quality and social deprivation in the UK: an environmental inequalities analysis, 2006 3 Defra. Abatement cost guidance for valuing changes in air quality, May 2013


LAQM Annual Status Report 2020 ii

implement the action named Safer Accessible Routes, there is now a part time officer

in post, this provides a dedicated person to progress this and similar projects across

North Yorkshire.

We are currently undertaking a trial of low cost sensors as part of a Defra air quality

grant. The trial will continue over the next year, and will incorporate a variety of

projects.

Conclusions and Priorities

Over the 2019 monitoring year, there has been one exceedance of the annual mean

objective for nitrogen dioxide (NO2) this was within the Bond End, Knaresborough

AQMA. This means that three out of four AQMA’s have not had any exceedances of

the NO2 annual mean objective over 2019. The trend across the district in 2019 was

one of decreasing concentrations. HBC is not proposing to revoke any AQMA’s at

the current time.

The priorities for the year are to:

Advance the investigation into an engineering solution for Ripon, working with

NYCC

Continue work with Public Health at NYCC, and NYCC Sustainable Travel

officers

Continue working on the Defra grant funded project of trialling low cost

sensors.

The biggest challenge for the advancement of projects in 2020 is the

Coronavirus pandemic, projects have already been delayed.

Local Engagement and How to get Involved

HBC has previously set up an Officer group comprising of HBC and NYCC officers,

and a Councillor Steering group. Meetings of the two groups continue to occur,

although at a lesser frequency, to develop and progress the action plan.

We hope that by carrying out education projects we will be informing the public how

they can improve local air quality. A key point of the consultation exercise was that

the majority of people were prepared to walk more, use the bus, share a lift, cycle

more, or use a lower emission vehicle to improve air quality within the Harrogate

district.

1 Local Air Quality Management

This report provides an overview of air quality in the Harrogate district during 2019. It

fulfils the requirements of Local Air Quality Management (LAQM) as set out in Part IV

of the Environment Act (1995) and the relevant Policy and Technical Guidance

documents.

The LAQM process places an obligation on all local authorities to regularly review

and assess air quality in their areas, and to determine whether or not the air quality

objectives are likely to be achieved. Where an exceedance is considered likely the

local authority must declare an Air Quality Management Area (AQMA) and prepare

an Air Quality Action Plan (AQAP) setting out the measures it intends to put in place

in pursuit of the objectives. This Annual Status Report (ASR) is an annual

requirement showing the strategies employed by Harrogate Borough Council (HBC)

to improve air quality and any progress that has been made.

The statutory air quality objectives applicable to LAQM in England can be found in

Table E.1 in Appendix E.



2 Actions to Improve Air Quality

2.1 Air Quality Management Areas

Air Quality Management Areas (AQMAs) are declared when there is an exceedance

or likely exceedance of an air quality objective. After declaration, the authority must

prepare an Air Quality Action Plan (AQAP) within 12-18 months setting out measures

it intends to put in place in pursuit of compliance with the objectives.

A summary of AQMAs declared by HBC can be found in

2.2 Progress and Impact of Measures to address Air Quality in the Harrogate district

Defra’s appraisal of last year’s ASR concluded:

Trends are clearly presented and discussed and a robust comparison with air

quality objectives is provided.

The diffusion tube mapping is comprehensive and clearly demonstrates the

monitoring network. AQMAs are also clearly shown on the maps.

Data capture during 2018 was good at all monitoring locations. Annualisation

was carried out for site H30 because only 8 months of monitoring took place.

Calculations for this were shown.

The fall off with distance calculator has been used for one location in the

district, this is site H39. A copy of the completed distance from kerb calculator

is shown.

The new Action Plan prioritises measures that specifically target pollution

hotspots. The Council has been proactive in already actioning measures.

There doesn’t appear to be an action plan measure specific to the Wetherby

Road, Harrogate AQMA but a combination of the measures would contribute to

reducing concentrations.

Priorities and measures expected to be implemented during the next reporting

year are clearly outlined in the report.

There are specific measures aimed at addressing PM2.5 emissions.

The report makes links to Public Health Outcomes Frameworks. This is

encouraged to continue in future ASRs.

Comments from the previous appraisal are provided and have been addressed.

Harrogate Borough Council has taken forward a number of direct measures during

the current reporting year of 2019 in pursuit of improving local air quality. Details of

all measures completed, in progress or planned are set out in Table 2.2.

More detail on these measures can be found in the Action Plan. Key completed

measures are:

HBC Ultra-low emissions strategy – work is now ongoing on the

implementation of the recommendations from the strategy.



Bond End junction improvement – concentrations within the AQMA have

decreased at all locations, with only one monitoring point breaching the

objective.

HBC’s priorities for the coming year are to:

Advance the investigation into an engineering solution for Ripon, ideas have

been discussed at the Councillor Steering group; these ideas need to be

investigated further by the Highway Authority.

Continue working with the Public Health team at NYCC on their projects, work

in this has been delayed due to the current pandemic.

Work with NYCC and King James School on projects using the mobile kit we

are trialling as part of the Defra air quality grant.

Continue work on air quality projects and education.

Continue trialling the air quality monitoring kit (Defra air quality grant).

The principal challenges and barriers to implementation that HBC anticipates facing

are due to restrictions because of the current COVID-19 pandemic. Projects have

already been delayed due to the current situation. Should daily life not return to

normal there is the risk that work will be delayed further.

2.3 PM2.5 – Local Authority Approach to Reducing Emissions and/or Concentrations

As detailed in Policy Guidance LAQM.PG16 (Chapter 7), local authorities are

expected to work towards reducing emissions and/or concentrations of PM2.5

(particulate matter with an aerodynamic diameter of 2.5µm or less). There is clear

evidence that PM2.5 has a significant impact on human health, including premature

mortality, allergic reactions, and cardiovascular diseases.

HBC is taking the following measures to address PM2.5:

In line with the Policy Guidance (PG16) HBC have opted to identify measures

already in place within the current air quality action plan that will help with reducing

levels of PM2.5, we consider that all of the measures within the current action plan will

have a positive effect on PM2.5 concentrations. We are working with a number of

parties on the actions within the action plan, including HBC Transport Planners and

NYCC Public Health and Sustainable Transport officers.

HBC are also providing local residents, via the website, with information on stoves,

open fires and seasoned wood, produced by Defra, as these have been identified as

an increasing source of PM2.5 across the country. HBC have smoke control areas

within Harrogate and Tockwith village, but not in Knaresborough or Ripon.

Continuous PM2.5 monitoring that has been carried out by City of York Council and

Leeds City Council has shown annual averages for 2019 ranging from 10.63 to 12.35

µg/m3. Given the consistent concentrations across the two districts which Harrogate

sits in the middle of, it is not unrealistic to predict that concentrations would be a

similar level within the Harrogate district.

The Public Health Outcomes Framework (PHOF), a department of Health data tool

for England intended to focus public health action on increasing health life

expectancy and reducing differences in life expectancy between communities, uses

indicators to assess improvements. Due to the significant impact that poor air quality

can have on health, the PHOF includes an indicator relating to PM2.5. The indicator is

PHOF indicator D01 Fraction of mortality attributable to particulate air pollution.

Estimates of mortality in England (2018 data) range from 2.4% (Isles of Scilly) to

7.1% (City of London). In the Harrogate district, the indicator value is 3.8%, which is



the third lowest in the Yorkshire and Humber region. The value for the whole region

is 4.5%.

HBC plans to continue working within departments within HBC and NYCC, including

Public Health, to ensure the delivery of action within the action plan, and to develop

further actions in future. Consideration on the reduction of PM2.5 will continue when

new actions are being developed.



3 Air Quality Monitoring Data and Comparison with Air Quality Objectives and National Compliance

3.1 Summary of Monitoring Undertaken

3.1.1 Automatic Monitoring Sites

Harrogate Borough Council does not undertake any automatic monitoring.

3.1.2 Non-Automatic Monitoring Sites

Harrogate Borough Council undertook non- automatic (passive) monitoring of NO2 at

50 sites during 2019. Table A.2 Error! Reference source not found.in Appendix A

shows the details of the sites.

Maps showing the location of the monitoring sites are provided in Appendix D.

Further details on Quality Assurance/Quality Control (QA/QC) for the diffusion tubes,

including bias adjustments and any other adjustments applied (e.g. “annualisation”

and/or distance correction), are included in Appendix C.

3.2 Individual Pollutants

The air quality monitoring results presented in this section are, where relevant,

adjusted for bias4, “annualisation” (where the data capture falls below 75%), and

distance correction5. Further details on adjustments are provided in Appendix C.

3.2.1 Nitrogen Dioxide (NO2)

Table A.1 in Appendix A compares the ratified and adjusted monitored NO2 annual

mean concentrations for the past 5 years with the air quality objective of 40µg/m3.

Note that the concentration data presented in Table A.1 represents the concentration

at the location of the monitoring site, following the application of bias adjustment and

annualisation, as required (i.e. the values are exclusive of any consideration to fall-off

with distance adjustment).

For diffusion tubes, the full 2019 dataset of monthly mean values is provided in

Appendix B. Note that the concentration data presented in Table B.1 includes

distance corrected values, only where relevant.

4 https://laqm.defra.gov.uk/bias-adjustment-factors/bias-adjustment.html 5 Fall-off with distance correction criteria is provided in paragraph 7.77, LAQM.TG(16)

https://laqm.defra.gov.uk/bias-adjustment-factors/bias-adjustment.html



The concentrations within the Bond End Knaresborough AQMA have decreased at

all locations in 2019. The largest decrease was found at H14, with a decrease of 11.8

µg/m3, giving a concentration of 38.6 µg/m3. This location previously breached the air

quality objective. There remains one exceedence of the air quality objective at

location H13, with a concentration of 40.47 µg/m3, this has decreased from 45.53

µg/m3.

2019 is the first full year of monitoring data since works were undertaken by North

Yorkshire County Council within the Bond End AQMA. These works were to remove

the traffic lights and replace with mini roundabouts.

All four locations within the Knaresborough AQMA No. 2, referred to as the York

Place, Knaresborough AQMA, are below the annual mean objective and

concentrations at all have decreased in 2019. This is the third year where no

locations have breached the objective. The largest decrease in concentrations was at

site H53, with a change of 6.27 µg/m3, the concentration recorded was 26.75 µg/m3.

The highest recorded concentration was at H22 with 34.91 µg/m3. This is less than

88% of the objective.

At the six remaining existing sites in Knaresborough, all concentrations stayed below

the objective and all concentrations were lower than 2018.

One new location has been included for 2019, this is a residential receptor near to

Knaresborough Bus Station. The concentration recorded in 2019 was 33.84 µg/m3.

This location is also being monitored in 2020.

The concentrations within the Ripon AQMA have decreased at 6 locations in 2019,

and increased by 0.01 µg/m3 at the remaining location within the AQMA. All locations

are below the objective level. The greatest change was seen at location H10 with a

decrease of 5.03 µg/m3, giving a concentration of 27.4 µg/m3. The highest

concentration recorded within the AQMA was below 88% of the objective, this is the

result from triplicate tubes H4/5/25 and is a concentration of 34.98 µg/m3.

Out of the remaining locations in Ripon, four monitoring locations decreased when

compared to 2018 and one marginally increased. All concentrations were less than

70% of the air quality objective.

2019 concentrations within the Harrogate AQMA have reduced at all locations, and

there are no exceedances of the air quality objective. The Harrogate AQMA consists



of a first floor residential flat, there are currently three diffusion tubes located on the

property, one at first floor level and two at ground floor level. The greatest decrease

was seen at location H34, with a change of 6.17 µg/m3. The highest concentration is

less than 90% of the objective, and reduced from 41.44 µg/m3 in 2018 to 35.87 µg/m3

in 2019.

Diffusion tubes H42 and H43 are located on Station Parade and the Station

Parade/Albert Street junction in Harrogate; they have been placed at these locations

to assess if there may be a breach of the hourly mean. In 2019, location H42

recorded a concentration of 33.6 µg/m3, which is a decrease of 9.47 µg/m3 from

2018. The concentration from location H43 was 21.13 µg/m3, a decrease of 4.62

µg/m3 from 2018.

The main conclusions of the 2019 monitoring are that:

There have no exceedances of the annual mean objective for Nitrogen

Dioxide in three out of the four air quality management areas.

In the Bond End, Knaresborough AQMA, there was only one monitoring

location which breached the objective, in 2018 there were three locations.

The concentration at H14 within the Bond End AQMA, decreased by 11.8

µg/m3, this is following highways junctions works, which were completed in

November 2018.

There has been a decrease in concentrations at all but three monitoring

locations across the district.

☒ Diffusion tube data has been bias corrected

☒ Annualisation has been conducted where data capture is <75%

☒ Reported concentrations are those at the location of the monitoring site (bias adjusted and annualised, as required), i.e. prior to any fall-off with

distance adjustment

Notes:

Exceedances of the NO2 annual mean objective of 40µg/m3 are shown in bold.

NO2 annual means exceeding 60µg/m3, indicating a potential exceedance of the NO2 1-hour mean objective are shown in bold and underlined.

(1) Data capture for the monitoring period, in cases where monitoring was only carried out for part of the year.

(2) Data capture for the full calendar year (e.g. if monitoring was carried out for 6 months, the maximum data capture for the full calendar year is 50%).

(3) Means for diffusion tubes have been corrected for bias. All means have been “annualised” as per Boxes 7.9 and 7.10 in LAQM.TG16 if valid data capture for the full calendar year is less than 75%. See Appendix C for details.

(4) Concentrations are those at the location of monitoring and not those following any fall-off with distance adjustment.

Appendix C: Supporting Technical Information / Air Quality Monitoring Data QA/QC

C.1 Supply and analysis of nitrogen dioxide diffusion tubes

The nitrogen dioxide diffusion tubes are supplied and analysed by West Yorkshire

Analytical Services. The tubes are prepared with 50% TEA in acetone.

West Yorkshire Analytical Services have taken part in the Air NO2 Proficiency Testing

Scheme. During the period Jan-Feb, Apr-May and Jul-Aug the lab had 100%

satisfactory results, and in Sep- Nov the lab had 50% satisfactory results.

The results of precision testing show that West Yorkshire Analytical Services had

“Good” and “Bad” precision for 2018. Tube precision is separated into two categories,

“Good” or “Poor”, tubes are considered to have good precision where the coefficient

of variation of duplicate or triplicate diffusion tubes for eight or more periods during

the year is less than 20% and the average CV of all monitoring periods is less than

10%.

Harrogate Borough Council has used the national diffusion tube bias adjustment

factor spreadsheet. The factor for 2019 is 0.8.

C.2 NO2 fall-off with distance calculator

The fall of with distance calculator has been used for one location in the district, this

is site reference H39. A copy of the completed distance from kerb calculator is shown

below.



C.3 Annualisation Process

Annualisation has been carried out for two sites in the study which had 7 and 8

months data. This equates to 58% and 67%. %. The annualisation process has been

carried out in line with the guidance in Box 7.10 of TG(16). The annualised results

have been included and highlighted in the annual monitoring results. Details of the

process carried out for each site are shown below.
