___________________________________________________________________ To: Communities and Housing Policy Board On: 31 October 2023 ___________________________________________________________________ Report by: Director of Environment, Housing and Infrastructure ___________________________________________________________________ Heading: Renfrewshire’s Local Air Quality Management Update – 2023 Air Quality Annual Progress Report ___________________________________________________________________ 1. Summary 1.1 This report provides an update in relation to air quality within Renfrewshire and details the findings of the Council’s most recent Local Air Quality Management report, Renfrewshire’s 2023 Annual Progress Report. 1.2 The 2023 Annual Progress Report reviewed air quality monitoring data from 2022. There were no exceedances of any quality objectives identified within Renfrewshire during 2022 with concentrations of nitrogen dioxide (NO2) and particulate matter (PM) continuing to show a downward trend. 1.3 There have now been three consecutive years of compliance with statutory objective levels throughout all of Renfrewshire and eight years of compliance within Paisley and the Paisley Town Centre Air Quality Management Area. The legislative framework permits Air Quality Management Areas to be amended or revoked and Scottish Government Policy Guidance recommends that, as a minimum there will normally be at least three consecutive years where the pollutants of concern are complying with the relevant objective levels. Environment, Housing and Infrastructure will continue with the current monitoring programme throughout 2023/24 before consideration will be given to amending or revoking any of the Council’s three Air Quality Management Areas. ___________________________________________________________________ 2. Recommendations It is recommended that the Infrastructure, Land and Environment Policy Board: 2.1 Notes the outcome of Renfrewshire’s 2023 Air Quality Annual Progress Report and that there were no exceedances of any quality objectives identified within Renfrewshire during 2022. _________________________________________________________

3. Background 3.1 Air quality is directly related to a number of key Scottish Government National Outcomes and policy priorities, notably those focussed on the environment, sustainable places, environmental impact and healthier lives. 3.2 In accordance with the Local Air Quality Management statutory process introduced by the Environment Act 1995, all local authorities are required to undertake a regular review and assessment of air quality within their area and submit their findings by means of an Annual Progress Report to the Scottish Government by the end of June each year for approval. Environment, Housing and Infrastructure have submitted the Annual Progress Report which has now been approved by the Scottish Government. 3.3 The Annual Progress Report provides an overview of air quality within Renfrewshire during 2022. It includes a review of 2022 pollutant monitoring data and atmospheric emissions sources within Renfrewshire and compares the available data to national air quality standards. 3.4 The main pollutants of concern within Renfrewshire are NO2 and PM. There are currently three Air Quality Management Areas (AQMAs) declared within Renfrewshire; the Paisley Town Centre AQMA declared August 2009 and the Johnstone High Street and Renfrew Town Centre AQMAs declared August 2016. 3.5 In 2022 the Council operated three automatic monitoring sites (Cockels Loan, Renfrew, Inchinnan Road, Renfrew and High St, Johnstone) which measured NO2 or PM concentrations. Concentrations recorded at all automatic monitoring sites were below the annual mean and short-term objective levels for both pollutants. 3.6 Monitoring of NO2 was also undertaken via a network of sixty-two NO2 diffusion tube sites throughout Renfrewshire with no exceedances recorded at any of these sites. A largely downward trend in concentrations continues to be observed across the Council’s 2022 monitoring data, with only seven NO2 diffusion tube sites experiencing an increase in annual mean NO2 concentration from 2021 to 2022, with the remaining experiencing a decrease. Broadly, over the past five years, the majority of the diffusion tube monitoring sites have shown a decrease in NO2 concentrations. 3.7 Within the Paisley Town Centre Air Quality Management Area there have now been eight consecutive years of compliance with statutory objective levels within Paisley. The legislative framework permits Air Quality Management Areas to be amended or revoked and Scottish Government Policy Guidance recommends that, as a minimum there will normally be at least three consecutive years where the pollutants of concern are complying with the relevant objective levels. There are various reasons why the Paisley Town Centre AQMA has not been revoked yet and presently we are awaiting finalisation of significant infrastructure projects to the north of the Paisley AQMA which may impact on road traffic in that area.

3.8 In terms of the Johnstone High Street AQMA and Renfrew Town Centre AQMA, there have now been three consecutive years of compliance with statutory objective levels throughout these areas. In Johnstone, we have had no exceedances of NO2 since 2018 when there was a reading of 40ug/m3 (the objective level being 40ug/m3) at one diffusion tube site. Within Renfrew, there was one marginal exceedance at a diffusion tube site in 2019 with a reading of 41.4ug/m3. Environment, Housing and Infrastructure will continue with the current monitoring programme throughout 2023/24 and collate a further years’ worth of monitoring data before consideration will be given to amending or revoking the Johnstone and Renfrew Air Quality Management Areas. 3.9 No further action is required by the Council other than to progress with updating the 2019 Renfrewshire Air Quality Action Plan. An update to this is due by spring 2024 and will be submitted to the Board for approval in due course. ___________________________________________________________________ Implications of the Report 1.

Renfrewshire Council LAQM Annual Progress Report 2023 i Executive Summary: Air Quality in Our Area Air Quality in Renfrewshire Council There are currently three Air Quality Management Areas (AQMAs) within Renfrewshire Council. The AQMAs are located within Paisley Town Centre (PTC), Johnstone High Street (JHS) and Renfrew Town Centre (RTC). The AQMAs have been declared due to exceedances of the air quality objective (AQO) levels for nitrogen dioxide (NO2) and particulate matter (PM10, PTC only). There continue to be no exceedances of either the NO2 or PM10 AQOs at the automatic and passive monitoring locations within any of the AQMAs as reported in this APR. Renfrewshire Council monitor NO2, PM10 and PM2.5 at a number of locations. Renfrewshire Council undertook automatic (continuous) monitoring at three sites during 2022 – REN1 (Renfrew Cockels Loan), REN02 (Renfrewshire Johnstone), REN03 (Renfrew Inchinnan Road). REN1 and REN03 monitor NO2 while REN02 monitors PM10 and PM2.5. The monitored concentrations of NO2 continue to show the downward trend observed across Renfrewshire for the majority of the past decade, and there were no exceedances of the relevant AQOs reported during 2022. Concentrations of the annual mean and relevant short- term objectives for NO2, PM10 and PM2.5 recorded at all automatic monitoring sites during 2022 were below AQO levels. There were a total of 62 diffusion tube monitoring sites across Renfrewshire in 2022, six sites were either added to the diffusion tube monitoring network or changed in the network from 2021. The details of these are as follows: Paisley88 was removed in August due to low return rates and was not replaced; Paisley95 was removed in February due to building works and was replaced by Paisley106; Johnstone106 was removed in March due to building works and was replaced by Johnstone107; Paisley104 was removed in June due to low return rates and was replaced by Paisley108. Three additional new sites were introduced in 2022 – Paisley102, Paisley103 and Paisley105. Actions to Improve Air Quality Throughout 2022, several sustainable travel-based measures detailed within the 2019 Air Quality Action Plan (AQAP) have been progressed to improve air quality throughout Renfrewshire, all measures and their progress are discussed in Section 2.3 Implementation of Air Quality Action Plan(s) and/or measures to address air quality.

Renfrewshire Council LAQM Annual Progress Report 2023 ii Renfrewshire Council ran three schemes in 2022 to encourage active travel – Better Points active travel incentive scheme, Living Streets WOW project walk to school challenge, and Beat the Street competition where competitors tap Beat the Streets cards on Beat Boxes to record distances walked or cycled. Additionally, the Paisley to Renfrew and Inchinnan Active Travel Routes were constructed and the Cycle2Work Scheme was open from March – June 2022. Fourteen measures are within the existing AQAP, they cover the following topic categories: • Transport Planning and Infrastructure; • Traffic Management; • Promoting Travel Alternatives; • Promoting Low Emission Transport; • Freight and Delivery Management; • Vehicle Fleet Efficiency; • Alternatives to Private Vehicle Use; • Policy Guidance and Development Control; and • Public Information. Local Priorities and Challenges Renfrewshire Council’s priorities following the publication of the 2023 APR are as follows: • Progress with the significant new road and cycle infrastructure projects which are part of the City Deals and AMIDS South projects; • Publication of a new Renfrewshire Local Transport Strategy and development of a Paisley Town Centre Transport Strategy; • Continuation with the upgrade and development of the cycling network as per the Renfrewshire Council Cycle Strategy priorities; • Improvement of the council’s fleet, funded via the Council’s Vehicle Replacement Capital Programme. £2.2 million has been set aside for the VRC Programme in 2023-24 for the purchase of new fleet vehicles. This includes the replacement of older fossil vehicles with newer fleet vehicles with better emission standards and the introduction of HVO as an alternative fuel for some of the fleet;
Page 9
Renfrewshire Council LAQM Annual Progress Report 2023 iii • Reopening the Cycle2Work scheme in April 2023 and keeping it available for the full financial year; • Upgrading fleet tracking telemetric system fitted to all Council vehicles to optimise utilisation of fleet. This will be completed by end of May 2023; • Refresh the local transport strategy and active travel strategy/action plan; • Full review of the 2019 Renfrewshire Council AQAP in summer 2023 in order to have the review completed by next Spring which is in accordance with the new requirements of the Scottish Government’s Policy Guidance 2023 whereby the Scottish Government now requires all action plans are reviewed and republished on a five-yearly cycle from date of initial publication, which will be March 2024. This process will involve consultation with steering group members and a full update of the action plan measures. The updated AQAP will include new measures that are not listed within the 2019 AQAP such as Beat the Streets, Better Points Ltd.; • Continue to monitor NO2, PM10 and PM2.5 at all relevant locations throughout Renfrewshire; and • Submit the 2024 Annual Progress Report. Renfrewshire Council has no comment on challenges faced as air quality in the area has been steadily improving over the years. How to Get Involved The general public can find further information about air quality within Renfrewshire on the Renfrewshire Council website https://www.renfrewshire.gov.uk/airquality.

Renfrewshire Council LAQM Annual Progress Report 2023 1 1 Local Air Quality Management This report provides an overview of air quality in Renfrewshire Council during 2023. It fulfils the requirements of Local Air Quality Management (LAQM) as set out in Part IV of the Environment Act (1995), as amended by the Environment Act (2021), 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 Progress Report (APR) summarises the work being undertaken by Renfrewshire Council to improve air quality and any progress that has been made.

Renfrewshire Council LAQM Annual Progress Report 2023 2 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 publish and implement an Air Quality Action Plan (AQAP) within the shortest possible time and no later than 12 months of the date of AQMA Designation Order. The AQAP must set out measures the local authority intends to put in place in pursuit of the objectives within the shortest possible time. Measures should be provided with milestones and a final date for completion. The action plan itself should have a timescale for completion and for revocation of the AQMA. Where measures to reduce air pollution may require a longer timescale an action plan shall be reviewed and republished within five years of initial publication and then five-yearly thereafter. A summary of AQMAs declared by Renfrewshire Council can be found in Table 2.1. Further information related to declared or revoked AQMAs, including maps of AQMA boundaries are available online at https://www.scottishairquality.scot/laqm/aqma?id=382#!/la/462.

CAFS2 sets out how the Scottish Government and its partner organisations propose to further reduce air pollution to protect human health and fulfil Scotland’s legal responsibilities over the period 2021 – 2026. CAFS2 was published in July 2021 and replaces Cleaner Air for Scotland – The Road to a Healthier Future (CAFS), which was published in 2015. CAFS2 aims to achieve the ambitious vision for Scotland "to have the best air quality in Europe". A series of actions across a range of policy areas are outlined, a summary of which is available on the Scottish Government’s website. Progress by Renfrewshire Council against relevant actions for which local authorities are the lead delivery bodies within this strategy is demonstrated below. 2.2.1 Placemaking – Plans and Policies Local authorities with support from the Scottish Government will assess how effectively air quality is embedded in plans, policies, City Deals and other initiatives, and more generally in cross departmental working, identifying and addressing evidence, skills, awareness and operational gaps.
Page 17
Renfrewshire Council LAQM Annual Progress Report 2023 4 Renfrewshire Council has relevant initiatives in Transport and Climate Change, as detailed below: Transport – Avoiding Travel – T1 Renfrewshire Council has included a measure within their 2019 AQAP to develop a Corporate Travel Plan (Measure 14, Table 1.3) together with ongoing detailed reviews of transport plans within Paisley and Johnstone. A draft travel plan and travel directories were prepared and provided by a consultant at the end of 2019. The steering group had been planned for spring 2020 to finalise the travel plan, however due to the pandemic, this has now been put on hold. It is not yet known when the steering group may be established, as the pandemic has had a significant effect on staff work habits with the majority of non-frontline workers still working from home. The council has recently created and filled a permanent Active Travel Officer post within the councils Transportation and Development team. The post was created to assist delivery on a wide range of priority active travel and public transport infrastructure related projects within Renfrewshire as well as develop and deliver a Renfrewshire Active Travel Strategy. This will be aimed at all residents, business etc. across Renfrewshire and not solely for staff as per the Corporate Travel Plan. Climate Change – Effective co-ordination of climate change and air quality policies to deliver co-benefits – CC2 The Scottish Government expects any Scottish local authority which has or is currently developing a Sustainable Energy Action Plan to ensure that air quality considerations are covered. In addition to the Council’s 2014 Carbon Management Plan, and as discussed in the Council’s AQAP, Renfrewshire Council commissioned a study during 2019 to review the AQAP measures in line with CAFS objectives. As such, it was found that within the 16 AQAP measures listed, the decarbonising transport and low emission vehicle use aspects were strongly aligned with the CAFS strategy. 2.2.2 Transport – Low Emission Zones (LEZs) Local authorities working with Transport Scotland and SEPA will look at opportunities to promote zero-carbon city centres within the existing Low Emission Zones (LEZs) structure.
Page 18
Renfrewshire Council LAQM Annual Progress Report 2023 5 Renfrewshire Council has no LEZs established within the Local Authority area. Renfrewshire Council undertook a National Low Emission Framework Stage 1 Screening Appraisal as part of the 2020 APR and determined that the proposed air quality measures were sufficient as declared AQMAs either reported no exceedances in 2019, or LEZs were not considered appropriate due to AQMAs being restricted along a stretch of road. This position is not considered to have changed since the appraisal and LEZs remain to not be considered appropriate in Renfrewshire. 2.3 Implementation of Air Quality Action Plan(s) and/or measures to address air quality In order to ensure that local authorities implement the measures within an action plan by the timescales stated within that plan, the Scottish Government expects authorities to submit updates on progress through the APR process. Renfrewshire Council has taken forward a number of measures within the action plan during the current reporting year of 2022 in pursuit of improving local air quality and meeting the air quality objectives within the shortest possible time. 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 Air Quality Action Plan relating to each AQMA. Key completed measures for this reporting year are: • Measure 1 – Gaia Works are now substantially complete and the completed infrastructure is in use; • Measure 1 – Two AMIDS (Advanced Manufacturing Innovation District Scotland) buildings are now complete and occupied; • Measure 15 – Construction of Paisley to Renfrew and Inchinnan Active Travel Routes; and • Measure 16 – Cycle2Work Scheme open from 24 March 2022 to 17 June 2022. New measures for this reporting year that were not included within the 2019 AQAP but will be detailed in the 2024 AQAP update include the following: • Better Points active travel incentive scheme ran for 12 months from Spring 2022. Headline results include: • 654 users out of 917 replaced their last car journey with an active travel option;
Page 19
Renfrewshire Council LAQM Annual Progress Report 2023 6 • 75.9% of respondents agreed they used the car less than usual to get from place to place; • 73% of respondents agreed they would likely use the car less to get from place to place in the future; • 75.2% of respondents said they are more likely to walk or cycle to get from place to place in the future; • 66.4% of respondents said they are likely to use public transport to get from place to place in future; and • 76.7% of respondents said that the scheme has made them leave the car at home. • Living Streets WOW project is a year-round walk to school challenge undertaken within Renfrewshire in 2022/23 which rewards children and young people with badges for choosing an active travel method in going to school. Headline results include: • 6455 children engaged with the project; and • 259,208 sustainable and active travel journeys undertaken. • Beat the Street empowers communities to increase activity levels and improve health with a walking and cycling competition where participants tap their Beat the Street cards on Beat Boxes on lampposts to record distances walked or cycled. Headline results for 2021/22: • 6313 players; • 37% activity undertaken during typical commute travel periods thus the game encouraged people to use active modes of travel to get to school and work; • 2% decrease in car proportion travelling to school by car each day following the scheme; • 68% players reported walking more and 11% reported cycling or wheeling more; and • 79% players said they were likely or very likely to continue walking, cycling or wheeling for travel in future. • Scootability is a training programme aimed at P3/4 allowing children to learn the skills and knowledge to ride safely. 5 primary schools took part in 2022/23 and 292 pupils completed training. Progress on the following measures has been slower than expected due to:

Traffic Management (UTC, congestion management) Expected completion year - 2023 In progress Not funded (from external sources). Original defective loops repaired/ replaced in June 2017. Validation of traffic signals & PROM updates completed in November 2017. Spring 2023 - 66 sites’ communications improved to prevent dropouts and minimise frequency of traffic delay. Feasibility of extending UTC control to Johnstone being pursued but will be dependent on funding. 66 sites across 30 junctions throughout the council area have been upgraded to an externally hosted UTC system between 2020 and 2023. This is then followed with a 10-year maintenance contract at these sites to ensure signals remain as efficient as possible. The work to replace life- expired traffic signals continues. 4G communications between the signals and the system are being superseded by connections to the council’s fibre network and priority junctions continue to have their equipment replaced as needs and funding arise 3 Council Fleet Improvements - Continue to improve the standard of fleet Promoting Low Emission Transport (Company vehicle procurement - Prioritising uptake of low emission vehicles) Ongoing. There is an annual vehicle replacement programme (VRP) whereby vehicles at the end of their service life are replaced with an improved EURO standard or an electric alternative. In progress Not funded (from external sources). Funded via the Council’s Vehicle Replacement Capital Programme. Through the VRP programme we are always looking to invest in our fleet – 2.2m has been set aside for 2023-24 for purchase of new fleet vehicles, this will incorporate replacing older fossil vehicles with newer fleet vehicles with better emission standards The Council fleet consists of approx 500 vehicles of which >70% are of EURO V or VI standard. We have recently introduced HVO as an alternative fuel for some of our fleet – and are looking to expand the project to come in line with more vehicles on the fleet. Ongoing. The Council will continue to improve the standard of fleet and introduce greener vehicles where opportunities and funding permits. There are approx 80 HGV vehicles, 32 of which are EURO VI standard with the remaining 48 being of EURO V standard. The EURO V HGVs are prioritised for replacement with EURO VI vehicles. 4 Council Fleet Improvements - Increase numbers of electric vehicles (EVs) & associated charging infrastructure Promoting Low Emission Transport (Company vehicle procurement Ongoing. The Council will continue to introduce EVs & charging points where In progress Funded mainly via the Council’s Replacement Vehicle Programme and Transport Scotland’s Switched On Fleets funding.

There are now 124 council operated publicly available charging points in Renfrewshire and 89 charging bays for council vehicles across 14 council depots /buildings. charging infrastructure for light vans, HGVs and refuse collection vehicles In addition to pool cars, the council have 10 pool bikes for staff to use for business travel as part of the Business Travel Hierarchy. 5 Masternaut Connect Fleet Telemetric System - Upgrade of fleet tracking telemetric system fitted to all Council vehicles to optimise utilisation of fleet. The tracking system allows close monitoring of movement and operating status of all fleet vehicles. Freight and Delivery Management (Route management plans/ Strategic routing strategy for HGV's) Vehicle Fleet Efficiency (other) Masternaut Connect installed/ completed 2017. However new fleet tracking system being installed 31st May 2023 In progress Not funded (from external sources). Masternaut was originally installed in all council vehicles in 2009-10. This was upgraded to a newer Masternaut Connect version early 2017 which provided an easier reporting system and focused in more detail on driver behaviour, vehicle utilisation etc. A new fleet tracking system is being installed from 31st May 2023 System operational from April 2017. Dedicated member of staff employed from Autumn 2018. Masternaut is getting replaced on the 31st of May and a new supplier - UK Telematics - will be the fleet tracker system for the council. This will provide real time, web-based asset tracking system using GPS. This should improve fuel economy and provide departments with more in- depth reports about driver behaviour when in a fleet vehicle. 6 Renfrewshire Council Sustainable Travel Planning Scheme - Supply high mileage users with council cars and introduce a fleet of pool vehicles to replace business mileage for employees. - Pool bikes are available for staff to use to carry out Council business. Alternatives to Private Vehicle Use (Car clubs/ sharing schemes) Promoting Low Emission Transport Ongoing Phase 1 of scheme - introduced Oct 2018 and now complete. Phase 2 - introduced Jan 2019 and complete. Phase 3 – ongoing but delayed, Funded. The majority of funding for the EVs has come from Transport Scotland Switched On Fleet funding. Phase 1 of the scheme was introduced in 2018. This involved 35 vehicles being available for staff use within Environmental Services. Staff required to use the fleet cars in replacement of their own cars. Phase 2 was introduced Jan 2019 and involved pool cars being available for all other relevant staff Currently, there are 47 electric pool vehicles with 23 charger units located in Renfrewshire HQ. 300,000 miles have been travelled by pool vehicles since October 2018. Phase 3 – locating pool vehicles at other council buildings has started with EV charging units now installed at HCSP office in Paisley for Care at Home teams. Further

There is currently not the need for significant numbers of pool cars to be stationed at other council buildings. members across Renfrewshire House HQ. By the end of 2019 all pool cars based at Renfrewshire House were EVs and over 300 HQ staff are now using pool vehicles. Phase 3 involves locating pool vehicles at other Council buildings. EVs were delivered March 2021. 8 Renfrewshire’s Local Transport Strategy - Publication of a new Local Transport Strategy (LTS) to replace the Council’s 2007 LTS will be undertaken. Policy Guidance and Development Control (Other policy) New Renfrewshire LTS – expected completion 2024/25 In progress Not funded (from external sources). The Council’s 2007 LTS set out key objectives and vision for transport over 10-20 yrs. A refresh of this 2007 LTS was undertaken in Feb 2017. A new Renfrewshire LTS will be prepared following the policy guidelines in the National Transport Strategy 2020 and the Regional Transport Strategy 2023, which is currently awaiting Scottish Ministers approval. New Renfrewshire LTS is currently out to tender for consultancy support. A detailed scope of the council’s requirements includes consideration of its plan for net zero emissions by 2030. 9 Paisley Town Centre Transportation Improvements - Undertake a feasibility study of potential transport interventions for Paisley town centre e.g. reinstating two-way traffic flows, amending key junctions, Policy Guidance and Development Control (Other policy) Traffic Management (Congestion management) To be confirmed following further modelling In progress The feasibility study has been funded via SPT. Funding of any future proposed measures will be subject to availability of capital funding with the potential of funding from external partners also e.g. SPT. Procurement process for feasibility study awarded 2017. 2019 - first draft of the feasibility study produced which establishes initial proposals and reports on potential areas of improvement, their Ongoing. The proposed options are intentionally high level, providing ideas of key potential transport interventions for Paisley. Some of these measures will now be developed from the current concept phase taking into account traffic modelling and allowing for appropriate Funding of measures.

The development of a Transport Strategy for Paisley Town Centre (PTC) was identified as a key action within the Renfrewshire LTS and PTC 2016-2026 Action Plan. The conclusions of this feasibility study may feed into any PTC Transport Strategy. The conclusions will then be subject to senior management review, Board approval and consultation with stakeholders before any decisions are made on potential action measures. Implementation of final proposals will thereafter be subject to identification of funding streams. assessment, design and eventual delivery. Whilst a prioritised programme of works has been identified for the short to medium term, further modelling has yet to be undertaken and a timeline for implementation of the measures yet to be decided. Some long-term improvements are also identified in line with the PTC 10yr Action Plan, but these require further investigation. The draft feasibility study details a programme of phased interventions covering the short, medium and long term. 10 Johnstone Town Centre Transportation Improvements Policy Guidance and Development Control (Other policy) Traffic Management (Parking enforcement on Highway) Temporary measures have been completed. Permanent TRO changes to be pursued after the Renfrewshire consolidated digital TRO is made in 2023. In progress Not funded (from external sources). Yellow line restrictions and bus stop closures/relocations have been carried out under TTRO to enable a turning facility for buses around Houston Square. Permanent TRO changes to be pursued after the Renfrewshire consolidated digital TRO is made in 2023. Consideration is being given to Johnstone as an extension to the UTC system to better link and control signal junctions on High Street. .

Renfrewshire Council LAQM Annual Progress Report 2023 13 11 Improvements in the Bus Fleet Standard Vehicle Fleet Efficiency (Promoting Low Emission Public Transport) Ongoing In progress The purchase of these by the operator has been aided by the Scottish Ultra Low Emission Bus Scheme. An initial meeting was held in April 2019 with the management of the largest bus operator in Renfrewshire and staff from Renfrewshire Council to discuss the potential improvements in bus operations. The operator has since invested significantly in their EV fleet brining in 23 EV buses at the end of 2021 and used for local residential routes, therefore improving emissions locally. In addition, EV charging infrastructure has been installed in Johnstone and Inchinnan Depots. Further engagement required with other operators. Further meeting will be undertaken with local bus operators as part of the 2024 update to the Air Quality Action Plan 12 Vehicle Idling Awareness Raising - Regular targeted campaigns to raise awareness regarding idling vehicles & air pollution. Campaigns aimed at specific categories of drivers or in areas where vehicles idle unnecessarily e.g. schools, bus terminals, taxi ranks or in response to complaints. Traffic Management (Anti-idling enforcement) Public Information (via other mechanisms Ongoing. General idling awareness campaigns have been ongoing since 2011. On hold Not funded (from external sources). A School Parking Campaign was introduced in April 2018 aimed at road safety around schools including safe parking and an anti-idling message. Banners were erected at school entrances and every pupil received a school parking pledge leaflet which contained a message regarding no idling and encouraging parents to sign up to safe parking pledges around schools. By August 2019, all 49 Primary schools in Renfrewshire were engaged in the campaign. Regarding the second phase of the scheme, four primary schools have been identified to introduce an exclusion zone in the streets around their entrances as we aim to create a safer, healthier school environment for pupils. This was due to commence in April 2020 but has been put on hold. When it is next able to commence, it will consist of a six-month pilot scheme and will introduce a part-time

A feasibility study for this was undertaken in 2019. vehicle exclusion zone at the start and end of the school day in some of the surrounding streets of the four schools. 14 Renfrewshire Council Corporate Travel Plan Promoting Travel Alternatives (Workplace Travel Planning) Uncertain On hold Not funded (from external sources). Jan 2019 - Consultant undertook site visits to relevant council offices to determine existing facilities. June 2019 - staff travel survey issued to determine current transport modes etc. A Roadshow event was also held on Clean Air Day in June 2019 at Renfrewshire House. Council staff and the consultants were in attendance to provide travel planning advice, info on pool cars, promotion of the travel survey etc. Dr Bikes and Scotrail were also in attendance. A staff commuter challenge was undertaken in August 2019. Nov 2019 – draft plan provided by consultant A draft travel plan and travel directories were prepared and provided by the consultant during Nov 2019. A council steering group requires to be established to finalise the plan and then consultation of this with other relevant services/ organisations. This had been planned for spring 2020 but has now been put on hold due to the current pandemic. It is unclear when this stage will recommence. Once the plan is published and measures implemented a second staff survey is planned to determine any change in travel behaviour.

Renfrewshire Council LAQM Annual Progress Report 2023 15 15 Renfrewshire Council Cycle Strategy & Action Plan 2016-2025 - The strategy contains a Cycling Action Plan which sets out a programme of activities and network interventions for the coming ten years including upgrades and expansion of cycle networks, upgrading the Council’s facilities for cyclists and updating the Council’s Travel Plan. Promoting Travel Alternatives (Promotion of cycling) The Cycle Strategy and Action Plan runs from 2016-2025. Upgrades and development of the cycling network is ongoing as per the strategy priorities. Council will refresh Local Transport Strategy and Active Travel Strategy / Action Plan during 2023/24. In progress Funding is applied for each financial year from the Scottish Government under the Cycling, Walking and Safer Routes fund. At least 36% of this fund must be allocated to cycling including for example infrastructure or design works. Renfrewshire used 49.4% of CWSR budget in 2022/23 on new infrastructure to encourage cycling. Projects included construction of Paisley to Renfrew and Inchinnan Active Travel Routes. Designs for Erskine and Inchinnan Business Park. Sustrans funded projects completed in 22/23 include NCN improvements at Jennyswell, Miller Street Johnstone. The Cycle Strategy was approved by Board in Dec 2016. Measures contained within the action plan will be implemented dependant on funding. There are several cycling infrastructure projects which are currently at concept design /public consultation design stage. The routes for these are – 1.Southolm Roundabout Erskine 2.Linside Avenue 3.Hawkhead Rd/ Glasgow Rd junction 4.Linclive Roundabout 5. Inchinnan Business Park 6. Barnsford Road, Glasgow Airport 16 Renfrewshire Council Staff Cycling Incentives - Staff Cycle to Work Scheme. Cycle2Work Council employees can participate in this Government approved salary sacrifice scheme which allows them to purchase a bike and cycle accessories with tax free benefits. Promoting Travel Alternatives (Promotion of cycling) Ongoing In progress Not funded (from external sources). Staff can apply for anything between £100 and £2000 towards the cost of bike or cycle accessories which could potentially save up to £960 per person. The scheme was previously open from 24 March 2022 to 17 June 2022. Given its previous popularity, the Cycle2Work scheme was reopened in April 2023 and is now available all year round. Scheme currently open for uptake

Renfrewshire Council undertook automatic (continuous) monitoring at three sites during 2022. Table A.1 in Appendix A shows the details of the sites. National monitoring results are available at https://www.scottishairquality.scot/data. Two sites monitor NO2 – REN1 Renfrew Cockels Loan and REN03 Renfrew Inchinnan Road, with the final site REN02 Renfrewshire Johnstone monitoring PM2.5 and PM10. No exceedances of the relevant air quality objectives were recorded for any pollutant at any automatic monitoring station in 2022. No changes occurred to Renfrewshire Council’s automatic monitoring network in 2022. Gordon Street automatic continuous monitor was decommissioned in November 2021. The continuous monitor was old and required continual repairs and experienced issues with its main electrical feed prior to closure. No exceedances had been recorded in Paisley Town Centre for over five years, from either this continuous monitoring site or diffusion tube monitoring sites. Therefore, it was decided that this site was to be decommissioned rather than paying for continual repairs. A map showing the location of the monitoring sites are provided in Figure 1. Further details on how the monitors are calibrated and how the data has been adjusted are included in Appendix C. Non-Automatic Monitoring Sites Renfrewshire Council undertook non- automatic (passive) monitoring of NO2 at 60 sites during 2022, including three triplicate sites. Table A.2 in Appendix A shows the details of the sites.
Page 30
Renfrewshire Council LAQM Annual Progress Report 2023 17 The following changes to Renfrewshire Council’s diffusion tube network occurred during 2022: • Paisley88 was removed in August due to low return rates. • Paisley95 was removed in February due to building works and was replaced by Paisley106 • Johnstone106 was removed in March due to building works and was replaced by Johnstone107 • Paisley104 was removed in June due to low return rates and was replaced by Paisley108. Of the 60 diffusion tube monitoring sites across Renfrewshire in 2022, following bias adjustment and prior to the application of distance correction, there were no exceedances of the NO2 annual mean air quality objective recorded in 2022. Maps showing the location of the monitoring sites are provided in Figure 2 to Figure 5. 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. Other Monitoring Activities No other monitoring activities have been undertaken.

Renfrewshire Council LAQM Annual Progress Report 2023 23 3.2 Individual Pollutants The air quality monitoring results presented in this section are, where relevant, adjusted for annualisation and bias. Further details on adjustments are provided in Appendix C. 3.2.1 Nitrogen Dioxide (NO2) Table A.3 in Appendix A compares the ratified and adjusted monitored NO2 annual mean concentrations for the past five years with the air quality objective of 40 µg/m3. For diffusion tubes, the full 2022 dataset of monthly mean values is provided in Appendix B. There were six new sites established in 2022. Two diffusion tubes recorded a data capture below 25% and therefore could not be annualised, this data is still shown in (monthly table). Two diffusion tubes required annualisation as their data capture was between 25% and 75% - Renfrew70 and Paisley108. Distance correction was undertaken for two monitoring sites to estimate the concentration at the nearest receptor, with calculations provided in Table C.4 – Paisley21 (triplicate site) and Renfrew48. All diffusion tube monitoring locations in Renfrewshire Council achieved NO2 AQO compliance in 2022. The highest concentration was 30.9 µg/m3 reported at Johnstone59 (High Street). The observed downward trend in concentrations continues for the majority of monitoring sites in 2022. Only seven sites experienced an increase in annual mean NO2 concentration from 2021 to 2022, compared to 49 sites experiencing a decrease, these include REN03 – Renfrew Inchinnan Road automatic monitoring site and five diffusion tube locations (Paisley2, Renfrew8, Renfrew17, Renfrew68, Renfrew70 and Johnstone86). These increases range from +0.2 µg/m3 (at Johnstone86) to +2.3 µg/m3 (at Paisley2). The decreases observed range from -0.6 µg/m3 (Paisley3, Paisley44 and Paisley50) to -9.7 µg/m3 (Johnstone99). The remaining six sites were commissioned in 2023. Broadly, over the past five years, the majority of the diffusion tube monitoring sites have shown a decrease in NO2 concentrations. Table A.4 in Appendix A compares the ratified continuous monitored NO2 hourly mean concentrations for the past five years with the air quality objective of 200 µg/m3, not to be exceeded more than 18 times per year. No exceedances of the hourly mean air quality objective for NO2 were recorded at any of the automatic monitoring sites. None of the diffusion tube monitoring sites reported concentrations exceeding 60 µg/m3 which indicates that there are no exceedances of the short-term air quality objective.

Renfrewshire Council LAQM Annual Progress Report 2023 24 3.2.2 Particulate Matter (PM10) Table A.5 in Appendix A compares the ratified and adjusted monitored PM10 annual mean concentrations for the past five years with the air quality objective of 18 µg/m3 showing the ratified data and the ratified corrected data for REN02 (Renfrewshire, Johnstone). following the Scottish Government Guidance Note in relation to the measurement of ambient Particulate Matter (PM) and the LAQM reporting of measured concentrations issued in May 2023. REN02 (Renfrewshire, Johnstone) has shown variations in concentrations ranging from 10.2 µg/m3 to 16.3 µg/m3 for the ratified data and 11.3 µg/m3 to 17.9 µg/m3 in the ratified corrected data in the past five years. It should be noted that the PM10 annual mean in 2020 and 2021 may have been impacted by COVID-19 related lockdowns. The concentration in 2022 is a reduction of 0.8 – 0.9 µg/m3 compared to the concentration recorded in 2021. This site has not recorded an exceedance of the annual mean AQO since at least 2018. Table A.6 in Appendix A compares the ratified continuous monitored PM10 daily mean concentrations for the past five years with the air quality objective of 50 µg/m3, not to be exceeded more than seven times per year. In 2022, REN02 (Renfrewshire Johnstone) monitor reported no instances of 24-hour mean AQO exceedances. The 24-hour PM10 AQO was last exceeded in 2019 at REN02 – Renfrewshire Johnstone, this exceedance has been attributed to localised buildings works undertaken in summer 2019. 3.2.3 Particulate Matter (PM2.5) Table A.7 in Appendix A compares the ratified and ratified corrected monitored PM2.5 annual mean concentrations for the past five years with the air quality objective of 10 µg/m3. In 2022, REN02 (Renfrewshire Johnstone) recorded a concentration of 6.1 µg/m3 or a corrected value of 6.5 µg/m3, these both show a slight increase (+0.1 µg/m3 and +0.2 µg/m3 respectively) compared to the concentration reported in 2021 (6.0 µg/m3 and 6.3 µg/m3 respectivey) but a reduction compared to the concentrations in 2018 and 2019 (7.3 µg/m3 and 7.9 µg/m3 for the ratified annual mean and 7.7 µg/m3 and 8.4 µg/m3 for the corrected annual mean). However, it should be noted that the PM2.5 annual mean in 2020 and 2021 may have been impacted by COVID-19 related lockdowns. The site has not recorded an exceedance of the annual mean AQO since at least 2018.

Renfrewshire Council LAQM Annual Progress Report 2023 26 4 New Local Developments 4.1 Road Traffic Sources There are a number of developments within the local authority that may affect air quality, The following developments that will affect road traffic sources are outlined below: • 22/0363/PP - Advanced Manufacturing Innovation District Scotland (AMIDS) South project. Formation of 2 lane road, including a bridge crossing over the White Cart Water, road and footpath upgrades and other associated works. Site Linking Inchinnan Road and Harbour Road with Abercorn Street, Paisley. Two detailed air quality assessments were submitted for the application – the first being a Preliminary Air Quality Assessment relating to the construction phase of the development and then an Air Quality Addendum report for the operational phase road traffic impacts of the scheme. Both reports were found to be satisfactory with mitigation measures recommended in order to address potential dust issues from the construction phase. Development approved January 2023. • 22/0345/PP - Erection of residential development comprising eighty flats and thirty-nine dwellinghouses and formation of roads, infrastructure, and open space amenity. Site On Southern Edge of Roundabout Junction with Laymoor Avenue, King's Inch Road, Renfrew. A detailed air quality assessment was submitted with the application and found to be satisfactory. The assessment concluded there were no significant effects on air quality as a result of the development and therefore no requirement for mitigation measures. Development approved April 2023. • 22/0142/PP - Demolition of existing office building and erection of sixty-seven flats with associated access, landscaping, open space and parking. 2 Lonend Paisley PA1 1SS. A simple air quality assessment was submitted with this application (in accordance with relevant air quality and planning guidance based on the proposed number of traffic vehicle movements). The assessment determines that further quantitative assessment of local air quality is not required for the proposed future use of the scheme and that the air quality impact of the development was not considered to be significant. Development approved August 2022.

Renfrewshire Council LAQM Annual Progress Report 2023 28 5 Planning Applications The transport project within Paisley town centre known as AMIDS South was granted planning approval in January 2023. The project will create new routes between Paisley town centre and the Advanced Manufacturing Innovation District Scotland (AMIDS) and Glasgow Airport. The project involves a road bridge crossing the White Cart and an east- west link road, all with accompanying walking and cycling options. This is 90% funded by the UK Government Levelling Up Fund, with the rest paid by Renfrewshire Council. Two detailed air quality assessments were submitted with the application, a Preliminary Air Quality Assessment relating to the construction phase of the development and an Air Quality Addendum report for the operational phase road traffic impacts of the scheme. Both reports were found to be satisfactory. With regards to the operational phase, the assessment determines that there will be no exceedances of air quality objectives as a result of the development. There will also be a beneficial effect on annual mean NO2, PM10 and PM2.5 concentrations at the majority of locations assessed. In terms of public support for the development, more than 260 people completed a public survey with their thoughts on the project proposals. The survey found: • 90% would use the riverside route • 86% confirmed that they would be more likely to walk or cycle here following the infrastructure improvements • More than two-thirds of people would use the walking and cycling route between Gallowhill Road and Inchinnan Road • 70% indicated that they would consider leaving the car at home and walk or cycle instead A contractor for the development should be appointed by the end of 2023 with completion expected in 2025.

Renfrewshire Council LAQM Annual Progress Report 2023 29 6 Conclusions and Proposed Actions 6.1 Conclusions from New Monitoring Data There were no AQO exceedances identified in Renfrewshire Council during 2022. Historically, the Renfrew 8 diffusion tube monitoring site has exceeded the annual mean NO2 AQO however in 2021 the reported concentration was 29.8 µg/m3 and so this monitoring site fell below the AQO for the first time in at least five years. In 2022, the reported concentration was 30.2 µg/m3 and so still fell significantly below the AQO. 89% of existing monitoring sites recorded a decrease in annual mean NO2 concentrations from 2021 to 2022. The remaining sites experienced an increase in NO2 concentrations, including the REN03 Renfrew Inchinnan Road automatic monitoring site and five diffusion tube monitoring sites. PM10 annual mean concentrations at REN02 – Renfrewshire Johnstone decreased from 2021 to 2022 by 0.8 µg/m3 or by 0.9 µg/m3 for the corrected annual mean concentrations. REN02 – Renfrewshire Johnstone also records PM2.5 and experienced a small increase (+0.1 μg/m3 for the ratified annual mean concentrations or +0.3 µg/m3 for the corrected annual mean concentrations) from 2021 to 2022, both pollutants monitored at REN02 recorded concentrations below their respective annual mean AQOs. 6.2 Conclusions relating to New Local Developments Any new developments that are likely to impact local air quality, or potentially introduce new receptors into areas of poor air quality, have been adequately assessed during the planning process. No planning applications were received by Renfrewshire Council in 2022 that identified any new or significantly changed Non-Road, Industrial, Commercial or Domestic Sources or developments with fugitive or uncontrolled sources that had any human health concerns or impacts on vegetation or ecosystems. The air quality impacts were assessed to be not significant for two Road Traffic source planning applications submitted to Renfrewshire Council. The planning application reports relating to AMIDS South project were found to be satisfactory with construction phase dust

Renfrewshire Council LAQM Annual Progress Report 2023 30 mitigation measures. Renfrewshire Council are still awaiting an air quality assessment for the Mixed Use Redevelopment of Paisley Centre to be submitted. 6.3 Proposed Actions Renfrewshire Council’s proposed actions following the publication of the 2023 APR are as follows: • Progress with the significant new road and cycle infrastructure projects which are part of the City Deals and AMIDS South projects; • Publication of a new Renfrewshire Local Transport Strategy and development of a Paisley Town Centre Transport Strategy; • Continuation with the upgrade and development of the cycling network as per the Renfrewshire Council Cycle Strategy priorities; • Improvement of the council’s fleet, funded via the Council’s Vehicle Replacement Capital Programme. £2.2 million has been set aside for the VRC Programme in 2023-24 for the purchase of new fleet vehicles. This includes the replacement of older fossil vehicles with newer fleet vehicles with better emission standards and the introduction of HVO as an alternative fuel for some of the fleet; • Reopening the Cycle2Work scheme in April 2023 and keeping it available for the full financial year; • Upgrading fleet tracking telemetric system fitted to all Council vehicles to optimise utilisation of fleet. This will be completed by end of May 2023; • Refresh the local transport strategy and active travel strategy/action plan; • Full review of the 2019 Renfrewshire Council AQAP commencing summer 2023 in order to have the review completed by next Spring which is in accordance with the new requirements of the Scottish Government’s Policy Guidance 2023 whereby the Scottish Government now requires all action plans are reviewed and republished on a five-yearly cycle from date of initial publication, which will be March 2024. This process will involve consultation with steering group members and a full update of the action plan measures; • Continue to monitor NO2, PM10 and PM2.5 at all relevant locations throughout Renfrewshire; and • Submit the 2024 Annual Progress Report.

Renfrewshire Council LAQM Annual Progress Report 2023 53 Appendix C: Supporting Technical Information / Air Quality Monitoring Data QA/QC New or Changed Sources Identified Within Renfrewshire Council During 2023 Renfrewshire Council has not identified any new sources relating to air quality within the reporting year of 2022. Additional Air Quality Works Undertaken by Renfrewshire Council During 2023 Renfrewshire Council has not completed any additional works within the reporting year of 2022. QA/QC of Diffusion Tube Monitoring The diffusion tubes for the reporting year of 2022 were supplied and analysed by Glasgow Scientific Services (GSS) using the 20% TEA in water preparation method. All results have been bias adjusted and annualised (where required) before being presented in Appendix A: Monitoring Results. GSS is a UKAS accredited laboratory and participates in the AIR-PT Scheme (a continuation of the Workplace Analysis Scheme for Proficiency (WASP)) for NO2 tube analysis and the Annual Field Inter-Comparison Exercise. These provide strict performance criteria for participating laboratories to meet, thereby ensuring NO2 concentrations reported are of a high calibre. The latest AIR-PT results were as follows: • AIR-PT AR037 (May – June 2020) – No Results (NR) • AIR-PT AR039 (July – August 2020) – No Results (NR) • AIR-PT AR040 (September – October 2020) – 100% • AIR-PT AR042 (January – February 2021) – 50% • AIR-PT AR043 (May – June 2021) – 100%

Renfrewshire Council LAQM Annual Progress Report 2023 54 • AIR-PT AR045 (July – August 2021) – 100% • AIR-PT AR046 (September – October 2021) – No Results (NR) • AIR-PT AR049 (January – February 2022) – 100% • AIR-PT AR050 (May – June 2022) – 100% Diffusion Tube Annualisation Two diffusion tube monitoring locations within Renfrewshire Council required annualisation as their data capture was less than 75% but greater than 25%: Renfrew70 and Paisley108, details are provided in Table C.2. Two diffusion tube monitoring locations recorded a data capture below 25% and therefore could not be annualised: Paisley88 and Johnstone98. The remainder of the sites recorded a data capture greater than 75% and therefore did not require annualisation. Diffusion Tube Bias Adjustment Factors Renfrewshire Council have applied a local bias adjustment factor of 1.06 to the 2022 monitoring data. A summary of bias adjustment factors used by Renfrewshire Council over the past five years is presented in Table C.1. The 2022 national bias adjustment factor was taken from the National Diffusion Tube Bias Adjustment Factor Spreadsheet (version 03/23) of which reports six studies analysed by Glasgow Scientific Services in 2022 to give a national bias adjustment factor of 1.05. There were two locations which provided opportunity for input to local bias adjustment calculation. The local bias adjustment factor for 2022 was 1.06 from Cockels Loan co- location site, which reported good overall precision and overall data capture. Renfrew Inchinnan Road co-location site reported a poor overall precision for the diffusion tubes and therefore was not used to calculate the local bias adjustment factor as per LAQM.TG(22) which states “Where results show poor precision, then they should be treated with caution, and they may not be suitable for their intended purpose… The aim should be to use results from tubes that are giving good precision, as this will improve the overall reliability of the annual mean concentrations derived from the diffusion tubes to which the locally derived bias adjustment factors have been applied.” The local adjustment factor was used as it was larger than the national adjustment factor and was considered to provide a more conservative, worst case approach; this is consistent with the Council’s previous years’ choice of bias adjustment factors.

Table C.1 – Bias Adjustment Factor Year Local or National If National, Version of National Spreadsheet Adjustment Factor 2022 Local - 1.06 2021 National 03/22 1.12 2020 Local - 1.20 2019 Local - 0.89 2018 Local - 0.91 NO2 Fall-off with Distance from the Road Two monitoring sites (Paisley21 and Renfrew48) were not representative of exposure and so the NO2 fall-off with distance calculator was used to estimate the NO2 concentration at the nearest receptor with relevant exposure for each site. The calculations are shown in Table C.4. NO2 Fall-off with Distance from the Road was carried out using the Defra Diffusion Tube Data Processing Tool (https://laqm.defra.gov.uk/air-quality/air-quality- assessment/diffusion-tube-data-processing-tool/). QA/QC of Automatic Monitoring Automatic monitoring of NOX, PM10 and PM2.5 is completed within Renfrewshire using Chemiluminescence (NOX) and FIDAS 2000 (PM2.5 and PM10) analysers. Local Site Operator (LSO) duties are carried out by an Officer from Renfrewshire Council on a monthly basis. Automatic monitoring data is available on the Scottish Air Quality website (https://www.scottishairquality.scot/) both in real-time and following ratification by Ricardo Energy and Environment to AURN standards. The continuous monitoring sites are audited every six monthly by Ricardo and are serviced every six months by ACOEM who maintain the Service and Maintenance Contract. REN1 and REN03 NO2/NOx monitors are visited and calibrated once a month by an LSO from Renfrewshire Council and reports from these calibrations are sent to Ricardo to use in the QA/QC process.

Renfrewshire Council LAQM Annual Progress Report 2023 56 PM10 and PM2.5 Monitoring Adjustment PM10 and PM2.5 data have been corrected in line with the Scottish Government Guidance Note in relation to the measurement of ambient Particulate Matter (PM) and the LAQM reporting of measured concentrations, issued in May 2023. PM10 data have been corrected by dividing the ratified data by 0.909. PM2.5 data have been corrected by multiplying the ratified data by 1.06. Both the corrected and uncorrected values have been reported for completeness, as per the Scottish Government Guidance Note. Automatic Monitoring Annualisation Annualisation is required for any site with data capture less than 75% but greater than 25%. All automatic monitoring locations within Renfrewshire Council recorded data capture of greater than 75% therefore it was not required to annualise any monitoring data. NO2 Fall-off with Distance from the Road No automatic NO2 monitoring locations within Renfrewshire Council required distance correction during 2022.
