Air quality

""

In 2018 Waltham Forest Council commissioned King’s College London’s Environmental Research Group to model the impacts of recent road interventions in the borough, particularly the Enjoy Waltham Forest scheme, on air quality. 

The report found that that measures to prioritise pedestrians and cyclists such as segregated cycle lanes, increased pocket parks and timed road closures had made a marked contribution to improving air quality and health in the borough

The London Borough of Waltham Forest has been monitoring air quality across the borough since 1993.

We currently have three automatic monitoring sites:

  1. Dawlish Road urban background
  2. Crooked Billet kerbside
  3. Ruckholt Close roadside

All three sites monitor for PM10 and NO2. Data from all three sites is listed online for the public to freely access. Data collected from 1998 to March 2011 is listed in the London Air Quality Network (LAQN). Data collected from April 2011 onwards is listed in the Air Quality England (AQE) website.

In addition to the automatic monitoring sites, Waltham Forest also has 24 NO2 diffusion tube sites. Their locations are listed in our annual status report below.
The data from these monitoring sites has been used to model excrescences in the EU limit for annual NO2, specifically for relevant exposure. These studies have shown that the number of households exposed to more than the EU recommended maximum amount of Nitrogen Dioxide has dropped dramatically, from 58,000 in 2007 to just 6,300 in 2017. The full reports can be viewed below:

Mayor's Air Quality Fund Click to get info

The Mayor launched the third round of the Mayor’s Air Quality Fund as he visited Waltham Forest. He met with local business owners who use the Zero Emissions Delivery scheme and our Air Quality Ambassadors who are school children who have attended training in air quality and shared their views on improving air quality with deputy leader of the council and cabinet member for the environment Councillor Clyde Loakes.

The fund will allow London Boroughs to deliver air quality projects such as anti-idling projects, inspecting construction sites to ensure only lower-pollution machinery is used, Low Emission Neighbourhoods, pedestrianisation, road closures and car free schemes, and supporting the uptake of low-emission vehicles.

More information on the fund can be found on the Mayor of London website.

This year ahead of Clean Air Day we are inviting members of the London Environment Directors network to a cycling tour of the borough to discover some of the measures we have put in place to encourage our residents, staff and visitors to choose active travel methods and leave polluting transport modes behind. These include physical changes to our road network as well as cycle training and bike hire options for residents and visitors to provide access to one of the cheapest and healthy methods of getting around. 

On Clean Air Day itself we will also be carrying out our regular anti-idling operations in Walthamstow town centre, where we will be encouraging motorists to turn off their engines while dropping off passengers or waiting outside shops, to ensure everyone is breathing better air.

Councillors and staff are also getting involved and making pledges to help improve air quality for the day, and for the year. Some are committing to leaving the car at home on Clean Air Day, while others are pledging to cycle over a thousand miles this year.

The Environment Act 1995 Click to get info

The Environment Act 1995, Part IV requires councils to carry out a review and assessment of the air quality in their area. This process uses air pollution monitoring results, emission inventories, and pollution modelling to determine if the targets will be met.

Since 1988 Waltham Forest Council has produced various reports to comply with the requirements under the Environment Act 1995, Part IV. These reports include Updating and Screening Assessments, Detailed Assessments, Progress Reports as well as any other additional assessments if required. Based on the findings of these reports the whole borough of Waltham Forest was declared an Air Quality Management Area (AQMA) for NO2 and PM10 in 2002.

The following maps are modelled pollutant maps for the London Boroughs and districts of the North London Cluster Group; which includes the areas of Haringey, Enfield, Barnet, Harrow, Hertsmere, Epping Forest and Waltham Forest. (7 Boroughs/Districts):

The London Boroughs of Waltham Forest and Haringey have worked with Groundwork London to engage with nine schools to deliver an air pollution education programme (3862KB PDF file). The project engaged 5 primary schools in the London Borough of Haringey and 4 primary schools in the borough of Waltham Forest.

This project involved delivering a number of science based air pollution lessons looking at local air pollution levels via GIS and an investigation activity into the particulate levels at participating schools. This was followed by a creative workshop chosen by the school (ranging from travel related workshops, solar oven building or arts and crafts based creative exploration of the air quality theme). Schools also had the opportunity to receive an interactive 'fun' animation session about air pollution using the schools individual messages they wanted to portray, as well as the option to go on a field trip on the topic of sustainable cities. This project was to raise awareness of the risks that are associated with air pollution and the actions that can be taken to improve air quality.

According to Defra´s Air Quality Strategy for England, Scotland, Wales and Northern Ireland: “Air pollution is currently estimated to reduce the life expectancy of every person in the UK by an average of 7-8 months with estimated equivalent health costs of up to £20 billion each year. Air pollution also has a detrimental effect on our ecosystems and vegetation.”

The Air Quality Strategy 2007 details the government's standards and objectives for 8 main pollutants. The objectives have to be met by their respective target year. The pollutants of concern are:

  • Ozone
  • Benzene
  • 1,3 Butadiene
  • Sulphur Dioxide
  • Carbon Monoxide
  • Nitrogen Dioxide
  • PM10 (Particles/Dust below 10 microns in diameter)
  • Lead

The pollutants of concern today in Waltham Forest are nitrogen dioxide and particulates, or PM10’s. These pollutants are given off from motor vehicle exhausts and account for the majority of Waltham Forest’s air pollution problem. Pollutants given off from car exhausts, which are known to damage health, include carbon monoxide, benzene, nitrogen dioxide and particulates (microscopic specks of dust and soot).

These pollutants are often produced when the car engine is not working efficiently. Carbon monoxide is produced when the engine does not burn fuel efficiently, often because there is not enough air in the mixture. Benzene is a component of fuel and often ends up in exhaust gases.

Health effects Click to get info

PM10 Particulates

Particulates also referred to as particulate matter or fine particulates come from a variety of sources. These can include combustion sources (motor vehicles, biomass, bonfires, etc), secondary particles (sulphate and nitrate formed by chemical reactions in the atmosphere) and coarse particles (sea salt, soils, dusts, etc). Fine particulates can travel deep into the lungs which can cause inflammation and negatively impact on those with heart and lung diseases. Additionally, fine particulates can also carry carcinogenic compounds into ones respiratory system. Effects from Particulates can range from days of restricted activity to early death. Currently, the Air Quality Strategy 2007 sets a limit that PM10 cannot exceed 40ug/m3 as an annual mean.

Nitrogen Dioxide (NO2)

NO2 arises via the oxidation of nitric oxide by oxygen in the air. Primary sources of NO2 in Waltham Forest are vehicle emissions and other combustion sources such as gas boilers. This reddish brown gas can cause lung irritation and lower resistance to respiratory infections. It may also cause increased incidence of acute respiratory illness in children.

Benzene and 1,3 Butadiene

Volatile organic compounds from exhaust fumes, cigarette smoke, synthetic materials and household chemicals. Possible chronic health effects include cancer, central nervous system disorders, liver and kidney damage, reproductive disorders, and birth defects.

Carbon Monoxide

Carbon Monoxide (CO) is a colourless, odourless poisonous gas produced by incomplete, or inefficient, combustion of fuel. It is produced by the incomplete combustion of carbon containing materials such as smoking, car exhausts and unflued heating or cooking appliances.

CO can have an effect on mental activity and can worsen existing problems that affect the delivery of oxygen to the heart and lungs.

Sulphur Dioxide

This is produced from the burning of sulphur compounds that occur naturally in coal and oil.

At high levels, this acidic gas is an irritant that affects nerves in the lining of the nose, throat, lungs and airways. This, in turn, causes a cough and a feeling of chest tightening and may lead to a narrowing of the airways. This can affect asthmatics and people with chronic lung disease.

Ozone

This is caused by the reaction of nitrogen oxides with hydrocarbons in the presence of sunlight. At ground level it is a pollutant which reacts easily with biological materials.

At its highest levels in the UK, some people can experience discomfort and coughing, especially whilst taking exercise. It can inflame the airways, make eyes and throats sore and increase sensitivity to allergens e.g. pollen. People who suffer from asthma do not appear to be significantly more sensitive to ozone than other people.

Air pollution can also damage trees, plants and buildings and contribute to global warming. Waltham Forest needs to act now to protect our health and environment and improve our quality of life.

Lead

It is emitted into the atmosphere from vehicles using petrol containing lead and also from some industrial processes. Lead can affect many different parts of the body, including the production of blood, the nervous system and mental functioning.

Turn your key, be idle free

Leaving your engine on whilst parked emits a significant amount of pollution into the air.  These vehicle emissions present a significant risk to health, especially for younger children.

Facts

  • Did you know that children breathe 50% more air per body weight than adults?  Therefore if you are parked outside a school with your engine running, that's more pollution that the children are breathing into their lungs. You can prevent this by making sure you turn your car engine off while parked.
  • Did you know that leaving your engine running whilst parked wastes more fuel and costs you more at the pump?   Save yourself some money and turn your engine off while parked.
  • Did you know that you can warm the inside of your car quicker by driving it instead of leaving the engine on while parked? 
  • Did you know that idling is harder on the vehicle engine than restarting it? 
  • All of Waltham Forest is an air quality management area for poor air quality.  Help us improve air quality in the borough by turning your vehicle engine off while parked for longer than one minute.

Legislation

Although the Council has mainly focussed on raising awareness and influencing drivers to turn their vehicle engines off, the Council has also recently adopted anti-idling legislation which allows for officers to issue fixed penalty notices to drivers who fail to turn their engines off.

Anti-idling initiative

The Council is working with local residents to educate drivers about the negative impacts of leaving a vehicle engine running whilst parked.  Our volunteer Air Quality Champions will be working with the Council on chosen action days to engage with drivers.  If you would like to become an Air Quality Champion and volunteer to stop idling around schools, and other areas with sensitive receptors, get in touch.  Register your interest at EnvironmentalHealth@walthamforest.gov.uk

If you would like to report an area where vehicles are regularly left idling, please notify the Council on 0208 496 3000 or EnvironmentalHealth@walthamforest.gov.uk

Pollution penalty notice Click to get info

Part 3 of the Environmental Protection Act 1990 requires us to take reasonable steps to investigate and, if appropriate, to take action to in the event of justified complaints of statutory nuisance.

A Statutory Nuisance in this context can include emissions of smoke, fumes or gases, dust, steam and smell. The emissions must arise from premises and must materially affect the use of enjoyment or other premises.

Typical complaints are smoke and ash from garden bonfires, smoking chimneys, dust from building and demolition activity and cooking smells from restaurants. The legislation does not allow us to deal with complaints of smells arising from domestic premises.

If satisfied that a complaint of statutory nuisance is justified, an Abatement/Penalty Notice will be served upon the person responsible, occupier or owner of the premises (as appropriate) requiring that the nuisance be abated. Failure to comply with an Abatement/Penalty Notice is an offence and legal proceedings may result.

If you have an ideas or suggestions that could help us improve our services, please complete our feedback form and return to us.

There are many things that you can do to help reduce pollution levels and improve the quality of life for yourself, your family and others. Such as:

  • Walk
  • Cycle
  • Use public transportation
  • If you need to drive, limit the amount of small trips
  • Participate in car sharing schemes
  • Car pool
  • Avoid having bonfires
  • Only use exempt fireplaces and authorised fuels (you can find out more information about exempt fireplaces and authorised fuels)
  • Insulate your home
  • Regularly service your boiler

If you really need to use a car, you can help reduce pollution caused by vehicle emissions and so improve air quality in Waltham Forest by choosing a car with:

  • Catalytic converter
  • Oxidation catalyst
  • LPG powered
  • Use reduced sulphur in fuel
  • Electric powered vehicle
  • Regular vehicle maintenance and servicing – checking tuning, emission control and tyre pressure
  • Drive gently and slowly – this will reduce emissions and save fuel
  • Don’t leave your engine running when you are parked
  • If you are thinking of purchasing a new car, van or motorcycle choose one with the lowest air pollution emissions

It is emphasised that residents are responsible for avoiding smoke emission that causes a nuisance, as this is an offence.

Failure to comply with this information and advice may result in legal proceedings and financial penalties.

Smoke control areas Click to get info

Under the Clean Air Act the whole of the London Borough of Waltham Forest has been designated as a Smoke Control Area. Smoke control is important because this borough and much of London suffers from poor air quality which poses a significant risk to health.

The whole of the London Borough of Waltham Forest is a smoke control area, which means that it is an offence to emit smoke from a chimney of a building, or from a furnace or any fixed boiler. It is also an offence to use an 'unauthorised fuel' unless it is in an 'exempt' appliance. The current maximum fine is £1,000 for each offence.

If you use an open fire, stove, or other wood or coal burning appliance, you need to know what Council requirements apply. This page will inform you about what you can and can't do. If you need more information please visit the UK smoke control areas website, or email us at EnvironmentalHealth@walthamforest.gov.uk.

Please note that even with an exempt appliance or approved fuel, you may still cause a nuisance and are therefore not exempt from nuisance legislation. Please see the pollution penalty notice section of our page for more details.

Open fires in the home

You are able to enjoy a real fire at home on the condition that you burn smokeless coal or use certain specific types of wood burning stove or furnaces.

Smokeless coal is sold by some hardware shops, petrol filling station and DIY stores and is clearly labelled 'smokeless coal'. Smokeless fuels are officially authorized by the government and are listed on the DEFRA website. You must not burn any wood on an open fire, although a small amount of kindling or timber wood can be used to light the fire. If an Environmental Health Officer finds ordinary house coal, or another unauthorized fuel being burned in an open fireplace, she/he is obliged to serve notice to stop it because it is an offence under the Clean Air Act.

Some wood burning stoves and appliances are exempt from these restrictions. The DEFRA website has an extensive list of appliances that are exempt and which includes wood burning stoves, room heaters, cookers and other kinds of furnace and the fuels that can be used with them. Authorised fuels have passed tests to show that they can burn in an open fireplace without producing smoke. Stoves and other appliances are different from open hearths in that they are enclosed and have ventilation controls to regulate the burning process at a high temperature.

There are plans to bring in stricter regulations on the emissions to wood burning and multi fuel stoves. Ecodesign is the European Union’s programme for lowering emissions across Europe. DEFRA has confirmed its commitment to Ecodesign, as it will introduce stricter limits on emissions. Ecodesign is due to be implemented on 1st January 2022 and will introduce new emission limits that are significantly lower and more comprehensive than those required for DEFRA Exemption. There are many manufacturers of stoves who have already manufacture ‘ecodesign ready’ appliances that meet the future efficiency and emission limits. 

Grills and log burning ovens in restaurants

Charcoal grills for cooking meat and fish are not permitted inside restaurants as the government has not included charcoal grills in its list of exempt appliances, or charcoal as an authorised fuel. However, a gas fired or electric grill would be permitted.

If you wish to serve traditional pizzas in your restaurant using a log burning oven, there are some solid fuel pizza ovens included in the list of exempted appliances that you may use. As well as authorised fuels the list of exempted appliances can be found on the government’s website www.uksmokecontrolareas.co.uk.

Any appliance giving off cooking fumes must be properly ventilated to outside air. In most cases in the borough, adequate ventilation which doesn’t cause a nuisance to neighbours will mean filtered mechanical extract ventilation with an outlet at high level. Advice for this can be obtained from the Environmental Health Department by emailing EnvironmentalHealth@walthamforest.gov.uk 

Chimney heights

Under section 14 of the Clean Air Act 1993 it is an offence to cause a furnace to, or to knowingly permit a furnace to:

  • burn pulverised fuel;
  • burn at a rate of 45.4 kg or more an hour any other solid matter; or
  • burn at a rate equivalent to 366.4 kW or more any liquid or gaseous matter;

unless we have approved the height of the chimney, and you have adhered to any conditions we have attached to our approval.

If you apply for chimney height approval you must provide enough information to enable us to make the necessary calculations.

The local authority must consider an application for approval for chimney height for a furnace and give a written decision within 28 days of receipt, unless we've agreed in writing with you that a longer period is allowed. If we fail to deal with the application within this period, then approval without qualification is given.

You should use the 3rd Edition of the Clean Air Act Memorandum on Chimney Heights for guidance in order to establish the height of any proposed chimney. It's published by Her Majesty's Stationery Office (HMSO). The Memorandum is not a statutory document. It provides a relatively simple method of calculating the approximate height of chimneys desirable in normal circumstances."
