The site of a chemical factory with gross land contamination is not the best construction site for homes and retail. Was the sale and planning permission just a ruse to let Carmarthenshire County Council and NRW off the hook as toxic chemicals are likely leaching into the Burry Inlet , the supposedly protected NATURA site and shellfish fishery. The new owners , Castletown Estates are apparently listed offshore and have accepted responsibility for the clean up, But the company, registered in the Isle of Mann, shows no sign of actually getting on with the decontamination . A derelict site known to have chemical contamination is not what the residents of Burry Port want. Despite being informed by Llanelli Flood Forum members that indicative tests of the water leaching out of the site into the Habour shows several heavy metals, CCC have declined to test the water formally.

Grillo Site
Burry Port
Harbour
It is now 10 years
since the former Grillo Zinc oxide production factory adjacent to Burry Port
harbour was sold and demolished in 2007 and the site has lain dormant since then and
debris remains on the site.
The site adjacent to
Burry port Harbour has in its time been various metalworking establishments
finally up until its demolition a site for Zinc Oxide manufacturing.
The site is
contaminated with a cocktail of toxic metal, organic and inorganic compounds
all with risk to public health.
Carmarthenshire County
Council were aware, that, by allowing planning for housing development on that
site, would probably trigger a call in by the Welsh Government/Environment Agency.
In a
Planning Committee on January 18 th 2011, the planning committee were advised
by senior officers of Carmarthenshire County Council “ that, as the Committee was minded to approve planning application
S/18723, subject to the conditions detailed within the Report/Addendum of the
Head of Planning and/or reported at the meeting, the Head of Planning be
granted plenary powers to deal with any outstanding matters once the Article 14
Notice is withdrawn, or the application is called-in for determination,
inclusive of the Appropriate Assessment being signed off by CCW within a
reasonable time period from forwarding the same, in accordance with the
provisions of Regulation 43(1) of the Conservation of Habitats & Species
Regulations 2010 and inclusive also of a Section 106 Agreement”
In other words Carmarthenshire County
Council accepted the fact that this development was on a Classified C2
floodplain., which should not , due to the risk of flooding, have any development except vital utilities eg sewage pumps.
In correspondence from
the Environment Agency Wales, responsibility for monitoring the site and its
associated ground water, is the developer.
Camarthenshire County Council has been made aware of actions to be taken
including post remedial monitoring of groundwater. The Environment Agency understands that
ground water beneath the site is in continuity with open water within Burry
Port Harbour.
The Environment Agency
Wales will continue to act as an advisor to the Local Authority for matters
that could impact on ground or surface waters when requested.
In respect of the
future development of the site, the site is proposed for residential purposes
and some community asset, given the present economic restrictions and uncertain
waste disposal system quality, should a change of use of the site be considered
to one of emphasis on social and cultural asset?
The Llanelli Star has
published articles based on the views of a number of elected Councillors of
Pembrey and Burry Port Town Council.
These views, in favour of developing the
Harbour Area to the proposed planning applications and that failure to do so
would be detrimental to the future prosperity of Burry Port. The views
vociferously expounded appear to be
based on the principle that the proposed development area has never flooded and
that the flood maps have now been changed to show, that the development areas
are not on a flood plain.
Unfortunately this view, only supports a
part of the facts surrounding the flood risks for these sites, and does not
support the real facts as expounded by both Natural Resources Wales and
Watermans .
Both organizations have submitted their
assessments of flood risk to Carmarthenshire County Council and can be accessed
from the County’s Planning Applications sites.
Firstly Natural Resources Wales, in their
document, whilst they advise, that their Flood Map Information, updated shows
the site to be flood free, they acknowledge, that Site 6 lies partially within
the current C2 Zone as defined by the Development Advice Maps (DAM) referred to
under Technical Advice Note (TAN)15 Development and Flood Risk (July 2004).
They qualify this statement by advising that
their information does not take into consideration climate change allowances or
blockages at structures through which flood water passes.
They go on to say” In accordance with TAN 15
the proposed development of up to 134 residential properties would be
considered as highly vulnerable and should not be permitted within zone
C2. However, if your authority are
minded to consider the application it should be shown through the submission of
an appropriate flood consequences assessment (FCA) that the consequences of
flooding can be acceptably be managed over the lifetime of the development.
The NRW document makes reference to a Flood
Consequences Assessment “Redevelopment of Burry Port-Sites 5&6 Flood
Consequences Assessment Final. July 2014 Referenced 16025/FCA02A prepared by
Waterman Transport and Development Ltd”
and submitted to the
Authority forming part of the Planning Application documentation.
The document discusses Tidal Flood Risk and
comments that the principle risk of flooding at the site is potential tidal
flooding in the future. The principle cause is the effect of Climate Change in
terms of tidal flood risk.
TAN 15 states that provision must be made
for future changes in flood risk, specifically as a result of Climate Change.
In this case flood risk must be considered over the anticipated lifetime of each development.
It is proposed to
develop sites 5&6 for residential use; therefore a lifetime of development
of 100 years has been assumed giving an assessment year of 2114, and as the
Department for Environment Food and Rural Affairs (DEFRA) has produced guidance regarding sea level
rises for 2114, sea level rise is 14.5 mm/year.
The FCA concludes that the site remains dry
in the majority of the scenarios modelled, however the site is at risk of
flooding during a 0.1% plus climate change annual probability tidal event and
an extreme 0.5% annual probability tidal event plus climate change and with
tidal levels at the upper extent of the confidence interval. The FCA therefore
proposes mitigation in the form of raising ground elevations to 7.1 meters AOD
to address flood risk. We accept that the proposed mitigation works effectively
to create a plateau that remains flood free for all scenarios considered within
the FCA.
The proposed mitigation increases flood risk
on the B4311 to the west of the site and significant flood risk on the adjacent
former Grillo site requiring mitigation by a similar raising of ground elevations to 7.1m AOD
To counteract the lack
of suitable waste management facilities by Welsh Water, it should be made
incumbent on the developer to incorporate all the current waste disposable
systems that are environmentally sustainable and friendly into the plans for
the build.
Site remediation
continues to be priority, as no attempt has been made since demolition to clean
up the site. This is now becoming a critical issue.
Remediation costs will
be extensive, perhaps under current economic conditions beyond the means of any
developer. The solution in this case is European funding backed by Welsh
Government.
This solution would
clear the ground for Community assets for cultural community and recreation to
meet conditions of a Local Development Plan as well as creating employment
opportunities for the local community. The site stands on a designated flood
plain, the development called in by the Environment Agency on behalf of the
Welsh Government to restrict the building
of houses.
A buy back from the
developer and clean up funded by Public Finance is a logical solution to a problem
considered to be an ongoing one.
