Dear Sir/Madam,
Thank you for consulting Thames Water on the above document. Thames Water is the statutory sewerage undertaker for part of the Borough and is hence a "specific consultation body" in accordance with the Town & Country Planning (Local Development) Regulations 2012.
Planning Policies
Thames Water support the proposed policies within the Pre-submission Local Plan. Notwithstanding this it is suggested that minor modifications are made to the text within Policies SP01 and SP04 in order to ensure that the policies are effective in relation to ensuring development is delivered alongside any necessary sewerage infrastructure reinforcement works required to support it. The proposed modifications are set out in the attached response forms. In relation to Policy NE02 the requirement for engagement with sewerage providers is welcomed. To assist with promoting early engagement it would be beneficial if a link to Thames Waters pre-application service could be provided on the Councils website. Details regarding Thames Waters pre-application service can be found at: www.thameswater.co.uk/preplanning

Site Specific Comments
We have undertaken a high level review of the proposed site allocations within the Thames Water catchment and have appended comments in relation to wastewater infrastructure issues for these sites in table below.
R04 & R05 - Ford Headquarters and Council Depot, Warley: The wastewater network capacity in this area may be unable to support the demand anticipated from this development. Local upgrades to the existing drainage infrastructure may be required to ensure sufficient capacity is brought forward ahead of the development. Where there is a potential wastewater network capacity constraint, the developer should liaise with Thames Water to determine whether a detailed drainage strategy informing what infrastructure is required, where, when and
how it will be delivered is required. The detailed drainage strategy should be submitted with the planning application. R06 - Land off Nags Head Lane, Brentwood The wastewater network capacity in this area may be unable to support the demand
anticipated from this development. Local upgrades to the existing drainage infrastructure may be required to ensure sufficient capacity is brought forward ahead of the development. Where there is a potential wastewater network capacity constraint, the developer should liaise with Thames Water to determine whether a detailed drainage strategy informing what infrastructure is required, where, when and how it will be delivered is required. The detailed drainage strategy should be submitted with the planning application.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network. Thames Water therefore support the content of Policy NE2 parts D and E and
encourage developers proposing developments to engage with them at an early stage to discuss the
wastewater infrastructure requirements for development.
The proposed policy ensures that the Local Plan is consistent with Paragraphs 20 and 41 of the NPPF.
Alongside the proposed amended text for Policy SP04, the policy will help ensure the effective
delivery of any sewerage network reinforcement works necessary to support development.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network.
Thames Water support the policy in principle. However, it should be noted that new sewerage
infrastructure is delivered by the sewerage undertaker and funded through the infrastructure charge
for new developments connecting to the sewerage network. It is not therefore possible for any
necessary upgrades to be secured through CIL or S106 contributions. In order to ensure that any
necessary sewerage infrastructure reinforcement works required to support a development are
delivered ahead of the occupation of development it may be necessary for planning conditions to be
used to ensure that a development or phase of development is not occupied until the required
upgrade has been delivered. To help ensure this Policy SP04 should make reference to the use of
planning conditions as a mechanism to ensure the delivery of infrastructure alongside S106
agreements and CIL.

To address the above concern Part B of Policy SP04 could be amended to incorporate the following
wording:
"c. off-site capacity improvement works (secured through appropriate planning conditions or
agreements)"
The proposed change would ensure that planning conditions can be used to secure infrastructure
improvements necessary to support development alongside S106 agreements and CIL thereby
ensuring that the policy is effective and the Local Plan is sound.

POLICY SP01:
Thames Water support the aim of Policy SP01 (D) in relation to ensuring development does not result
in unacceptable impacts on amenity. However, as worded the policy would only be effective in
ensuring that development itself has no unacceptable impact on amenity. Consideration is also
required to be given to whether the location of proposed development is appropriate taking into
account existing sources of noise, odour and vibration to ensure that the amenity of future occupiers
of development will not be adversely affected by such issues. Where development would be affected
by an existing source of noise, odour or vibration development should only be allowed where it is
demonstrated that suitable mitigation measures can be put in place and it has been demonstrated
how these will be delivered. This would be required in order to ensure that the policy is consistent
with Paragraph 182 of the NPPF 2019.
To address the above concern it is considered that Part D(e) of Policy SP01 could be revised to read as
follows:
"e. has no unacceptable effect on health, the environment or amenity due to the release of pollutants
(such as light, noise pollution, vibration, odour, smoke, ash, dust and grit) to land, water or air, and
where the amenity of future occupiers would not be adversely impacted by existing sources of such
pollutants unless suitable mitigation measures are proposed and secured;"
The additional wording would ensure that development is not located where the amenity of future
residents would be affected by existing sources of polluntants unless suitable mitigation is provided.
This would ensure that the policy is effective and consistent with the NPPF and therefore sound.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network. Thames Water therefore support the content of Policy NE2 parts D and E and
encourage developers proposing developments to engage with them at an early stage to discuss the
wastewater infrastructure requirements for development.
The proposed policy ensures that the Local Plan is consistent with Paragraphs 20 and 41 of the NPPF.
Alongside the proposed amended text for Policy SP04, the policy will help ensure the effective
delivery of any sewerage network reinforcement works necessary to support development.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network.
Thames Water support the policy in principle. However, it should be noted that new sewerage
infrastructure is delivered by the sewerage undertaker and funded through the infrastructure charge
for new developments connecting to the sewerage network. It is not therefore possible for any
necessary upgrades to be secured through CIL or S106 contributions. In order to ensure that any
necessary sewerage infrastructure reinforcement works required to support a development are
delivered ahead of the occupation of development it may be necessary for planning conditions to be
used to ensure that a development or phase of development is not occupied until the required
upgrade has been delivered. To help ensure this Policy SP04 should make reference to the use of
planning conditions as a mechanism to ensure the delivery of infrastructure alongside S106
agreements and CIL.

To address the above concern Part B of Policy SP04 could be amended to incorporate the following
wording:
"c. off-site capacity improvement works (secured through appropriate planning conditions or
agreements)"
The proposed change would ensure that planning conditions can be used to secure infrastructure
improvements necessary to support development alongside S106 agreements and CIL thereby
ensuring that the policy is effective and the Local Plan is sound.

POLICY SP01:
Thames Water support the aim of Policy SP01 (D) in relation to ensuring development does not result
in unacceptable impacts on amenity. However, as worded the policy would only be effective in
ensuring that development itself has no unacceptable impact on amenity. Consideration is also
required to be given to whether the location of proposed development is appropriate taking into
account existing sources of noise, odour and vibration to ensure that the amenity of future occupiers
of development will not be adversely affected by such issues. Where development would be affected
by an existing source of noise, odour or vibration development should only be allowed where it is
demonstrated that suitable mitigation measures can be put in place and it has been demonstrated
how these will be delivered. This would be required in order to ensure that the policy is consistent
with Paragraph 182 of the NPPF 2019.
To address the above concern it is considered that Part D(e) of Policy SP01 could be revised to read as
follows:
"e. has no unacceptable effect on health, the environment or amenity due to the release of pollutants
(such as light, noise pollution, vibration, odour, smoke, ash, dust and grit) to land, water or air, and
where the amenity of future occupiers would not be adversely impacted by existing sources of such
pollutants unless suitable mitigation measures are proposed and secured;"
The additional wording would ensure that development is not located where the amenity of future
residents would be affected by existing sources of polluntants unless suitable mitigation is provided.
This would ensure that the policy is effective and consistent with the NPPF and therefore sound.

Received: 19/03/2019

Respondent: Thames Water

Representation Summary:

The wastewater network capacity in this area may be unable to support the demand anticipated from this development. Local upgrades to the existing drainage infrastructure may be required to ensure sufficient capacity is brought forward ahead of the development. Where there is a potential wastewater network capacity constraint, the developer should liaise with Thames Water to determine whether a detailed drainage strategy informing what infrastructure is required, where, when and how it will be delivered is required.

Dear Sir/Madam,
Thank you for consulting Thames Water on the above document. Thames Water is the statutory sewerage undertaker for part of the Borough and is hence a "specific consultation body" in accordance with the Town & Country Planning (Local Development) Regulations 2012.
Planning Policies
Thames Water support the proposed policies within the Pre-submission Local Plan. Notwithstanding this it is suggested that minor modifications are made to the text within Policies SP01 and SP04 in order to ensure that the policies are effective in relation to ensuring development is delivered alongside any necessary sewerage infrastructure reinforcement works required to support it. The proposed modifications are set out in the attached response forms. In relation to Policy NE02 the requirement for engagement with sewerage providers is welcomed. To assist with promoting early engagement it would be beneficial if a link to Thames Waters pre-application service could be provided on the Councils website.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network. Thames Water therefore support the content of Policy NE2 parts D and E and
encourage developers proposing developments to engage with them at an early stage to discuss the
wastewater infrastructure requirements for development.
The proposed policy ensures that the Local Plan is consistent with Paragraphs 20 and 41 of the NPPF.
Alongside the proposed amended text for Policy SP04, the policy will help ensure the effective
delivery of any sewerage network reinforcement works necessary to support development.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network.
Thames Water support the policy in principle. However, it should be noted that new sewerage
infrastructure is delivered by the sewerage undertaker and funded through the infrastructure charge
for new developments connecting to the sewerage network. It is not therefore possible for any
necessary upgrades to be secured through CIL or S106 contributions. In order to ensure that any
necessary sewerage infrastructure reinforcement works required to support a development are
delivered ahead of the occupation of development it may be necessary for planning conditions to be
used to ensure that a development or phase of development is not occupied until the required
upgrade has been delivered. To help ensure this Policy SP04 should make reference to the use of
planning conditions as a mechanism to ensure the delivery of infrastructure alongside S106
agreements and CIL.

To address the above concern Part B of Policy SP04 could be amended to incorporate the following
wording:
"c. off-site capacity improvement works (secured through appropriate planning conditions or
agreements)"
The proposed change would ensure that planning conditions can be used to secure infrastructure
improvements necessary to support development alongside S106 agreements and CIL thereby
ensuring that the policy is effective and the Local Plan is sound.

POLICY SP01:
Thames Water support the aim of Policy SP01 (D) in relation to ensuring development does not result
in unacceptable impacts on amenity. However, as worded the policy would only be effective in
ensuring that development itself has no unacceptable impact on amenity. Consideration is also
required to be given to whether the location of proposed development is appropriate taking into
account existing sources of noise, odour and vibration to ensure that the amenity of future occupiers
of development will not be adversely affected by such issues. Where development would be affected
by an existing source of noise, odour or vibration development should only be allowed where it is
demonstrated that suitable mitigation measures can be put in place and it has been demonstrated
how these will be delivered. This would be required in order to ensure that the policy is consistent
with Paragraph 182 of the NPPF 2019.
To address the above concern it is considered that Part D(e) of Policy SP01 could be revised to read as
follows:
"e. has no unacceptable effect on health, the environment or amenity due to the release of pollutants
(such as light, noise pollution, vibration, odour, smoke, ash, dust and grit) to land, water or air, and
where the amenity of future occupiers would not be adversely impacted by existing sources of such
pollutants unless suitable mitigation measures are proposed and secured;"
The additional wording would ensure that development is not located where the amenity of future
residents would be affected by existing sources of polluntants unless suitable mitigation is provided.
This would ensure that the policy is effective and consistent with the NPPF and therefore sound.

Dear Sir/Madam,
Thank you for consulting Thames Water on the above document. Thames Water is the statutory sewerage undertaker for part of the Borough and is hence a "specific consultation body" in accordance with the Town & Country Planning (Local Development) Regulations 2012.
Planning Policies
Thames Water support the proposed policies within the Pre-submission Local Plan. Notwithstanding this it is suggested that minor modifications are made to the text within Policies SP01 and SP04 in order to ensure that the policies are effective in relation to ensuring development is delivered alongside any necessary sewerage infrastructure reinforcement works required to support it. The proposed modifications are set out in the attached response forms. In relation to Policy NE02 the requirement for engagement with sewerage providers is welcomed. To assist with promoting early engagement it would be beneficial if a link to Thames Waters pre-application service could be provided on the Councils website. Details regarding Thames Waters pre-application service can be found at: www.thameswater.co.uk/preplanning

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network. Thames Water therefore support the content of Policy NE2 parts D and E and
encourage developers proposing developments to engage with them at an early stage to discuss the
wastewater infrastructure requirements for development.
The proposed policy ensures that the Local Plan is consistent with Paragraphs 20 and 41 of the NPPF.
Alongside the proposed amended text for Policy SP04, the policy will help ensure the effective
delivery of any sewerage network reinforcement works necessary to support development.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network.
Thames Water support the policy in principle. However, it should be noted that new sewerage
infrastructure is delivered by the sewerage undertaker and funded through the infrastructure charge
for new developments connecting to the sewerage network. It is not therefore possible for any
necessary upgrades to be secured through CIL or S106 contributions. In order to ensure that any
necessary sewerage infrastructure reinforcement works required to support a development are
delivered ahead of the occupation of development it may be necessary for planning conditions to be
used to ensure that a development or phase of development is not occupied until the required
upgrade has been delivered. To help ensure this Policy SP04 should make reference to the use of
planning conditions as a mechanism to ensure the delivery of infrastructure alongside S106
agreements and CIL.

To address the above concern Part B of Policy SP04 could be amended to incorporate the following
wording:
"c. off-site capacity improvement works (secured through appropriate planning conditions or
agreements)"
The proposed change would ensure that planning conditions can be used to secure infrastructure
improvements necessary to support development alongside S106 agreements and CIL thereby
ensuring that the policy is effective and the Local Plan is sound.

POLICY SP01:
Thames Water support the aim of Policy SP01 (D) in relation to ensuring development does not result
in unacceptable impacts on amenity. However, as worded the policy would only be effective in
ensuring that development itself has no unacceptable impact on amenity. Consideration is also
required to be given to whether the location of proposed development is appropriate taking into
account existing sources of noise, odour and vibration to ensure that the amenity of future occupiers
of development will not be adversely affected by such issues. Where development would be affected
by an existing source of noise, odour or vibration development should only be allowed where it is
demonstrated that suitable mitigation measures can be put in place and it has been demonstrated
how these will be delivered. This would be required in order to ensure that the policy is consistent
with Paragraph 182 of the NPPF 2019.
To address the above concern it is considered that Part D(e) of Policy SP01 could be revised to read as
follows:
"e. has no unacceptable effect on health, the environment or amenity due to the release of pollutants
(such as light, noise pollution, vibration, odour, smoke, ash, dust and grit) to land, water or air, and
where the amenity of future occupiers would not be adversely impacted by existing sources of such
pollutants unless suitable mitigation measures are proposed and secured;"
The additional wording would ensure that development is not located where the amenity of future
residents would be affected by existing sources of polluntants unless suitable mitigation is provided.
This would ensure that the policy is effective and consistent with the NPPF and therefore sound.

Dear Sir/Madam,
Thank you for consulting Thames Water on the above document. Thames Water is the statutory sewerage undertaker for part of the Borough and is hence a "specific consultation body" in accordance with the Town & Country Planning (Local Development) Regulations 2012.
Planning Policies
Thames Water support the proposed policies within the Pre-submission Local Plan. Notwithstanding this it is suggested that minor modifications are made to the text within Policies SP01 and SP04 in order to ensure that the policies are effective in relation to ensuring development is delivered alongside any necessary sewerage infrastructure reinforcement works required to support it. The proposed modifications are set out in the attached response forms. In relation to Policy NE02 the requirement for engagement with sewerage providers is welcomed. To assist with promoting early engagement it would be beneficial if a link to Thames Waters pre-application service could be provided on the Councils website. Details regarding Thames Waters pre-application service can be found at: www.thameswater.co.uk/preplanning

Site Specific Comments
We have undertaken a high level review of the proposed site allocations within the Thames Water catchment and have appended comments in relation to wastewater infrastructure issues for these sites in table below.
R04 & R05 - Ford Headquarters and Council Depot, Warley: The wastewater network capacity in this area may be unable to support the demand anticipated from this development. Local upgrades to the existing drainage infrastructure may be required to ensure sufficient capacity is brought forward ahead of the development. Where there is a potential wastewater network capacity constraint, the developer should liaise with Thames Water to determine whether a detailed drainage strategy informing what infrastructure is required, where, when and
how it will be delivered is required. The detailed drainage strategy should be submitted with the planning application. R06 - Land off Nags Head Lane, Brentwood The wastewater network capacity in this area may be unable to support the demand
anticipated from this development. Local upgrades to the existing drainage infrastructure may be required to ensure sufficient capacity is brought forward ahead of the development. Where there is a potential wastewater network capacity constraint, the developer should liaise with Thames Water to determine whether a detailed drainage strategy informing what infrastructure is required, where, when and how it will be delivered is required.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network.
Thames Water support the policy in principle. However, it should be noted that new sewerage
infrastructure is delivered by the sewerage undertaker and funded through the infrastructure charge
for new developments connecting to the sewerage network. It is not therefore possible for any
necessary upgrades to be secured through CIL or S106 contributions. In order to ensure that any
necessary sewerage infrastructure reinforcement works required to support a development are
delivered ahead of the occupation of development it may be necessary for planning conditions to be
used to ensure that a development or phase of development is not occupied until the required
upgrade has been delivered. To help ensure this Policy SP04 should make reference to the use of
planning conditions as a mechanism to ensure the delivery of infrastructure alongside S106
agreements and CIL.

To address the above concern Part B of Policy SP04 could be amended to incorporate the following
wording:
"c. off-site capacity improvement works (secured through appropriate planning conditions or
agreements)"
The proposed change would ensure that planning conditions can be used to secure infrastructure
improvements necessary to support development alongside S106 agreements and CIL thereby
ensuring that the policy is effective and the Local Plan is sound.

POLICY SP01:
Thames Water support the aim of Policy SP01 (D) in relation to ensuring development does not result
in unacceptable impacts on amenity. However, as worded the policy would only be effective in
ensuring that development itself has no unacceptable impact on amenity. Consideration is also
required to be given to whether the location of proposed development is appropriate taking into
account existing sources of noise, odour and vibration to ensure that the amenity of future occupiers
of development will not be adversely affected by such issues. Where development would be affected
by an existing source of noise, odour or vibration development should only be allowed where it is
demonstrated that suitable mitigation measures can be put in place and it has been demonstrated
how these will be delivered. This would be required in order to ensure that the policy is consistent
with Paragraph 182 of the NPPF 2019.
To address the above concern it is considered that Part D(e) of Policy SP01 could be revised to read as
follows:
"e. has no unacceptable effect on health, the environment or amenity due to the release of pollutants
(such as light, noise pollution, vibration, odour, smoke, ash, dust and grit) to land, water or air, and
where the amenity of future occupiers would not be adversely impacted by existing sources of such
pollutants unless suitable mitigation measures are proposed and secured;"
The additional wording would ensure that development is not located where the amenity of future
residents would be affected by existing sources of polluntants unless suitable mitigation is provided.
This would ensure that the policy is effective and consistent with the NPPF and therefore sound.

Dear Sir/Madam,
Thank you for consulting Thames Water on the above document. Thames Water is the statutory sewerage undertaker for part of the Borough and is hence a "specific consultation body" in accordance with the Town & Country Planning (Local Development) Regulations 2012.
Planning Policies
Thames Water support the proposed policies within the Pre-submission Local Plan. Notwithstanding this it is suggested that minor modifications are made to the text within Policies SP01 and SP04 in order to ensure that the policies are effective in relation to ensuring development is delivered alongside any necessary sewerage infrastructure reinforcement works required to support it. The proposed modifications are set out in the attached response forms. In relation to Policy NE02 the requirement for engagement with sewerage providers is welcomed. To assist with promoting early engagement it would be beneficial if a link to Thames Waters pre-application service could be provided on the Councils website. Details regarding Thames Waters pre-application service can be found at: www.thameswater.co.uk/preplanning

Site Specific Comments
We have undertaken a high level review of the proposed site allocations within the Thames Water catchment and have appended comments in relation to wastewater infrastructure issues for these sites in table below.
R04 & R05 - Ford Headquarters and Council Depot, Warley: The wastewater network capacity in this area may be unable to support the demand anticipated from this development. Local upgrades to the existing drainage infrastructure may be required to ensure sufficient capacity is brought forward ahead of the development. Where there is a potential wastewater network capacity constraint, the developer should liaise with Thames Water to determine whether a detailed drainage strategy informing what infrastructure is required, where, when and
how it will be delivered is required. The detailed drainage strategy should be submitted with the planning application. R06 - Land off Nags Head Lane, Brentwood The wastewater network capacity in this area may be unable to support the demand
anticipated from this development. Local upgrades to the existing drainage infrastructure may be required to ensure sufficient capacity is brought forward ahead of the development. Where there is a potential wastewater network capacity constraint, the developer should liaise with Thames Water to determine whether a detailed drainage strategy informing what infrastructure is required, where, when and how it will be delivered is required. The detailed drainage strategy should be submitted with the planning application.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network. Thames Water therefore support the content of Policy NE2 parts D and E and
encourage developers proposing developments to engage with them at an early stage to discuss the
wastewater infrastructure requirements for development.
The proposed policy ensures that the Local Plan is consistent with Paragraphs 20 and 41 of the NPPF.
Alongside the proposed amended text for Policy SP04, the policy will help ensure the effective
delivery of any sewerage network reinforcement works necessary to support development.

POLICY SP04
In relation to wastewater infrastructure it will be essential that new development is aligned with any
necessary upgrades required to ensure that the development would not overload the existing
sewerage network.
Thames Water support the policy in principle. However, it should be noted that new sewerage
infrastructure is delivered by the sewerage undertaker and funded through the infrastructure charge
for new developments connecting to the sewerage network. It is not therefore possible for any
necessary upgrades to be secured through CIL or S106 contributions. In order to ensure that any
necessary sewerage infrastructure reinforcement works required to support a development are
delivered ahead of the occupation of development it may be necessary for planning conditions to be
used to ensure that a development or phase of development is not occupied until the required
upgrade has been delivered. To help ensure this Policy SP04 should make reference to the use of
planning conditions as a mechanism to ensure the delivery of infrastructure alongside S106
agreements and CIL.

To address the above concern Part B of Policy SP04 could be amended to incorporate the following
wording:
"c. off-site capacity improvement works (secured through appropriate planning conditions or
agreements)"
The proposed change would ensure that planning conditions can be used to secure infrastructure
improvements necessary to support development alongside S106 agreements and CIL thereby
ensuring that the policy is effective and the Local Plan is sound.

POLICY SP01:
Thames Water support the aim of Policy SP01 (D) in relation to ensuring development does not result
in unacceptable impacts on amenity. However, as worded the policy would only be effective in
ensuring that development itself has no unacceptable impact on amenity. Consideration is also
required to be given to whether the location of proposed development is appropriate taking into
account existing sources of noise, odour and vibration to ensure that the amenity of future occupiers
of development will not be adversely affected by such issues. Where development would be affected
by an existing source of noise, odour or vibration development should only be allowed where it is
demonstrated that suitable mitigation measures can be put in place and it has been demonstrated
how these will be delivered. This would be required in order to ensure that the policy is consistent
with Paragraph 182 of the NPPF 2019.
To address the above concern it is considered that Part D(e) of Policy SP01 could be revised to read as
follows:
"e. has no unacceptable effect on health, the environment or amenity due to the release of pollutants
(such as light, noise pollution, vibration, odour, smoke, ash, dust and grit) to land, water or air, and
where the amenity of future occupiers would not be adversely impacted by existing sources of such
pollutants unless suitable mitigation measures are proposed and secured;"
The additional wording would ensure that development is not located where the amenity of future
residents would be affected by existing sources of polluntants unless suitable mitigation is provided.
This would ensure that the policy is effective and consistent with the NPPF and therefore sound.
