Vauxhall vent

The request was successful.

Dear Transport for London,

Lambeth's latest air quality strategy says (bottom of p24] "Vauxhall LB5 has breached the annual mean objective of 40 μg m-3. This is the highest PM10 concentration ever recorded at the site. It is believed that the spikes recorded at the station since 2019 are due to contamination from a tube vent which belongs to Transport for London. The vent is situated immediately next to the air quality station’s sensors; it was previously sealed, and has been left open since 2019. Lambeth has tried liaising multiple times with Transport for London asking that the vent was closed or that pollution coming from the vent was mitigated. The pollution from the vent is contaminating the readings, and we therefore believe those not to be representative of PM10 levels in the Vauxhall area. We continue to liaise with TfL to agree on a solution." They add on p26 that the breach "is the highest breach ever recorded at one of our sites."

Please can you provide me with copies of any correspondence between TfL and LBL's transport, climate change or air quality teams in relation to the aforementioned correspondence regarding remedying the vent which is apparently causing the high readings?

Yours faithfully,

Ben Rymer

Dear Mr Rymer,

 

TfL Ref: EIR-1280-2122

 

Thank you again for your request of 15^th September 2021. You have asked
for information about a vent shaft at Vauxhall. Your request is being
considered under the terms of the Environmental Information Regulations
(EIRs).

 

Unfortunately - because of its complexity - we will be unable to resolve
your request within the initial statutory 20 working day deadline. This is
because there are a number of different teams and colleagues who could
potentially have been in correspondence with Lambeth Council on this issue
and we want to ensure we have exhausted all possibilities to locate all of
the correspondence that falls within the scope of your request.

 

To enable us to fully consider your request, in accordance with the EIRs
we have had to extend the deadline for providing a response to 8^th
November 2021. We are working to ensure that you receive a response before
this date. 

 

I apologise for the delay and any inconvenience this may cause you.

 

If you are not satisfied with this response, please read the attached
help-sheet entitled ‘Your Right to Appeal’

 

Yours sincerely,

Dear Mr Rymer,

 

TfL Ref: EIR-1280-2122

 

Thank you for your request received by Transport for London (TfL) on 15^th
September 2021 asking for information about a London Underground vent at
Vauxhall.

 

Your request has been considered in accordance with the requirements of
the Environmental Information Regulations and our information access
policy.

 

Specifically you asked:

 

“Lambeth's latest air quality strategy says (bottom of p24] "Vauxhall LB5
has breached the annual mean objective of 40 μg m-3. This is the highest
PM10 concentration ever recorded at the site. It is believed that the
spikes recorded at the station since 2019 are due to contamination from a
tube vent which belongs to Transport for London. The vent is situated
immediately next to the air quality station’s sensors; it was previously

Please can you provide me with copies of any correspondence between TfL
and LBL's transport, climate change or air quality teams in relation to
the aforementioned correspondence regarding remedying the vent which is
apparently causing the high readings?”

 

I can confirm that we hold the information you require. Copies of the
requested correspondence are attached. Note that the names and direct
contact details of external personnel, and the direct contact details of
TfL staff, have been redacted under Regulation 12(3) of the EIR, the
exception that protects against the unfair release of personal data.

 

It is accepted between Lambeth and TfL Officers that the vent shaft may be
giving readings to the Air Quality Monitoring Station (AQMS) which have
affected the accuracy. This does not mean that the shaft is releasing any
harmful pollutants, but it is affecting the efficiency of the AQMS.

 

You may be aware that TfL is proposing to introduce new Healthy Street
improvements to Vauxhall Cross. This includes introducing a new Bus
Station, two way roads, new cycleways and improved pedestrian crossings.
As part of this work Lambeth and TfL agreed to relocate the AQMS away from
the LU Vent Shaft. It is also proposed to raise the vent shaft so that any
air coming from the Underground is pushed away, up and above the new bus
station roof.

 

Due to the pandemic, the delivery of the Vauxhall Cross project has been
delayed and therefore we have advised Lambeth Officers that they should
consider moving the AQMS prior to the delivery of the Vauxhall Cross
project. They have agreed to look at suitable locations and should be able
to provide an update on timescales for delivery. We continue to liaise
with Lambeth on the issue.

 

TfL is committed to maintaining the cleanest air possible for our staff
and customers when using the Tube. This includes undertaking further
research into the potential health impacts of Tube dust, continuing to
improve our monitoring programme, and rolling out enhanced tunnel cleaning
regimes across the network. We're also funding studies of Tube dust, to
better understand the health risks associated with dust on the Tube, which
is different to dust found above ground. More information can be found on
the following page of our website:

to access it for any reason, please do not hesitate to contact me.

 

Please see the attached information sheet for details of your right to
appeal as well as information on copyright and what to do if you would
like to re-use any of the information we have disclosed.
