Dear Mr Smith

TfL Ref 0423-2021/22

Thank you again for your request received by Transport for London (TfL) on
29 May 2021. You have asked for information about the asbestos survey
reports for Hatton Cross and Heathrow Terminal 4 tube stations.

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 we are still collating the information we hold.

To enable us to fully consider your request, in accordance with the EIRs

response is now 26 July 2021. We are working hard to ensure that you
receive a response before this date. 

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

Dear Mr Smith

TfL Ref 0423-2021/22

Thank you for your request received by Transport for London (TfL) on 29
May 2021 asking for information about asbestos survey reports for Hatton
Cross and Heathrow Terminal 4 tube stations.

Your request has been considered in accordance with the requirements of
the Environmental Information Regulations and our information access
policy. I can confirm that we hold the information you require. You asked:
Please would it be possible to see the asbestos report for Hatton Cross
underground station, and Heathrow Terminal 4 underground station.

Please find attached the original Type 2 asbestos management surveys
undertaken at Hatton Cross and Heathrow T4. Since then further information
has been gathered following surveys, sampling, reinspection and remedial
work which is compiled in the attached asbestos registers. Each item is
assigned a reference number - using this reference further down or in the
attached appendix you can cross reference this to see (where available) a
photo of the known asbestos containing material and the location. The
last asbestos reinspection of Hatton Cross was on 5^th June 2020 and
Heathrow T4 was completed 4^th June 2020.

General Information

Asbestos is found throughout the Underground; in Public Areas the vast
majority of Asbestos Containing Materials (ACMs) are contained behind
station finishes and cannot be accessed by the general public. Where areas
of ACMs interface with the general public they are in a position where
they cause no risk to the general public or staff. All stations accessed
by the public and staff are re-inspected on a periodic basis to ensure
that no adverse damage has been caused to change this status. If it is
assessed and the status has changed for any reason, then a risk assessment
is undertaken which will result in either encapsulation, encasement, or
removal.

We have processes and procedures in place to ensure that the management of
asbestos is carried out in compliance with the Control of Asbestos
Regulations 2012. Some of the main requirements that London Underground
deliver under this regulation are listed below:

o Identify the location and condition of hazardous materials
o Maintain an asbestos register with known, presumed or strongly
presumed asbestos
o Assess and manage the risk of exposure
o Prepare, implement, review & monitor the management plan to manage the
risks
o Regularly inspect known instances of asbestos
o Provide information on the location and condition of the material to
anyone who is likely to disturb it
o Carry out management, refurbishment and / or pre-demolition surveys
when required
o Carry out airborne fibre monitoring where necessary
o Maintain records detailing when and where asbestos is removed, treated
and disposed
o Request and retain Waste Consignment Note upon transportation of
Hazardous Materials to Hazardous Waste Landfill site
o Hold relevant Asbestos Management Qualifications

It is London Underground’s policy to continue to safely manage ACMs
in-situ, through continued management surveys, re-inspections, risk
assessments and pre-work Refurbishment & Demolition (R&D) surveys. We also
carry out airborne fibre monitoring for asbestos as reassurance during
work on or near to asbestos containing materials.

Please note that in accordance with TfL’s obligations under the Data
Protection legislation some personal data has been removed, as required by
Regulation 13 of the Environmental Information Regulations. This is
because disclosure of this personal data would be a breach of the
legislation, specifically the first principle of the legislation, which
requires all processing of personal data to be fair and lawful. It would
not be fair to disclose this personal information when the individuals
have no expectation it would be disclosed and TfL has not satisfied one of
the conditions of Schedule 2 which would make the processing ‘fair’.

Please also note that we have redacted several station layout drawings
contained in the attachments as these diagrams contains information which
could adversely affect national security or public safety (in line with
regulation 12(5)(a) of the Environmental Information Regulations – which
includes an exception to the release of material that would adversely
affect the security of public buildings). The redacted information
contains detailed diagrams showing the station layout and the location of
and access into, non-public areas of the station and their release could
place members of the public and TfL staff at risk by highlighting areas on
the network which could be susceptible to being targeted by individuals
intent on causing disruption or harm to the London Underground network.

In this instance the exception has been applied as disclosure of this
information could assist any persons wishing to disrupt London’s transport
infrastructure by placing into the public domain information which would
otherwise not be available via other means. Whilst we make no suggestion
that you would use this information for anything other than you own
interest, disclosure of information under the EIR has to be regarded as a
disclosure to the public at large.

The application of exception 12(5)(a) has been subject to consideration of
the ‘Public Interest Test’ (in essence, consideration of whether the
greater public interest lies in applying the exception or in releasing the
material in any case). While we appreciate the expectation of transparency
from public bodies, in this instance we consider that the greater public
interest rests in withholding the excepted material (which is relatively
limited) to ensure the security of the site.

If this is not the information you are looking for, or if you are unable
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.

Yours sincerely
