Material Planning Considerations: Air and Water Quality


Air and Water Quality considerations focus on assessing and mitigating the impacts of a proposed development on the quality of air and water resources. These considerations ensure that new developments do not negatively affect the health, safety, and well-being of residents, ecosystems, and the environment.



Key Components of Air and Water Quality Considerations

  • Pollutant Emissions: Assess the sources and levels of pollutants such as nitrogen dioxide (NO2), particulate matter (PM10 and PM2.5), sulfur dioxide (SO2), carbon monoxide (CO), and volatile organic compounds (VOCs) emitted by the development.
  • Impact on Human Health: Evaluate the potential health impacts of air pollution on residents, particularly vulnerable groups such as children, the elderly, and those with respiratory conditions.
  • Cumulative Impact: Consider the cumulative impact of the development combined with other nearby sources of air pollution.

  • Surface Water: Assess the impact on the quality of surface water bodies such as rivers, lakes, and streams. This includes potential contamination from runoff, sedimentation, and discharge of pollutants.
  • Groundwater: Evaluate the potential for groundwater contamination, including the impact on aquifers and underground water resources.
  • Effluent Discharge: Assess the quality and treatment of effluent discharged from the development, ensuring it meets regulatory standards and does not harm water quality.

Air Quality Management: Implement measures to reduce air pollutant emissions, such as dust suppression during construction, use of low-emission vehicles, and incorporation of green infrastructure like trees and green roofs.

Water Quality Protection: Implement measures to protect water quality, such as sustainable drainage systems (SuDS), proper wastewater treatment, and erosion control practices.

  • National Air Quality Objectives: Ensure compliance with national air quality objectives and limits set by regulatory bodies such as the Environment Agency and local authorities.
  • Water Quality Standards: Ensure compliance with water quality standards and regulations, including those set by the Water Framework Directive and other relevant legislation.

  • Air Quality Monitoring: Establish monitoring programs to track air quality before, during, and after construction. Use data to adjust mitigation measures as needed.
  • Water Quality Monitoring: Implement water quality monitoring programs to ensure ongoing compliance with standards and detect any contamination early.


How Air and Water Quality Considerations Influence Planning Decisions

1. Environmental Impact Assessments (EIA):

Developments with potential significant impacts on air and water quality often require an EIA. This assessment evaluates the likely effects of the development and proposes mitigation measures.


2. Health Impact Assessments (HIA):

An HIA may be conducted to understand the potential health impacts of air and water pollution associated with the development. This helps inform decisions and mitigation strategies.


3. Policy Compliance:

Planning authorities ensure that proposed developments comply with relevant national and local policies related to air and water quality, including the National Planning Policy Framework (NPPF) and local planning guidelines.


4. Consultation with Regulatory Bodies:

Input from regulatory bodies such as the Environment Agency, local environmental health departments, and water authorities is crucial. Their expertise helps assess the impact and guide appropriate mitigation measures.


5. Public Consultation and Concerns:

Public consultation provides an opportunity for residents to express concerns about air and water quality impacts. These concerns are taken into account in the decision-making process.


Importance in Planning Applications

1. Public Health and Safety:

Protecting air and water quality is essential for safeguarding public health and preventing respiratory illnesses, waterborne diseases, and other health issues.


2. Environmental Protection:

Ensuring high air and water quality standards helps protect ecosystems, biodiversity, and natural habitats from degradation and pollution.


3. Sustainable Development:

Incorporating air and water quality considerations promotes sustainable development practices that minimize environmental impact and enhance quality of life.


4. Legal and Policy Compliance:

Adherence to air and water quality regulations is a legal requirement. Non-compliance can result in planning applications being refused or subject to legal challenges.


5. Economic Implications:

Poor air and water quality can lead to increased healthcare costs, reduced productivity, and negative impacts on property values. Ensuring good environmental quality supports economic stability and growth.


Conclusion


By thoroughly considering air and water quality in planning applications, planning authorities can ensure that new developments contribute positively to the health and well-being of residents and the environment. This comprehensive approach helps balance development needs with the protection of vital air and water resources, promoting sustainable and resilient communities.
