this adventure that was the remediation of
the old railway workshops of
Mexico
I think it’s a part that marked my life
Professional significantly to
early 2001 while working my
abortion lab studies
environmental aspects of the autonomous unit of
Aguascalientes received the call from the
Secretary General government
then governor of the state of
Aguascalientes invited me to talk
about the possibility that the
state government acquired the
workshops the old workshops
Ferrocarriles Nacionales de Mexico to
that this this site
will be part of the state’s patrimony
I was very excited writing a
article about the transfer of
electrons in the obesity system
mixed function in the renal cortex of the
rat
then I am good remediation of
the railway workshops for being a
very different subject and the truth is that no
I was very attracted
however, good, considering the
request
I went with him to the governor
and he told me they had the draft
buy them from the workshops or look for a
arrangement with national railways in
liquidation in order to acquire this
site
in the words of he wants is a site that
It is very big
this month we have many problems because
is contaminated and there is part inside
my cabinet that tells me it would be a
error of acquiring this this site because
we would not reach enough resources
to be able to remedy it
however another group within the same
home
the pp is very enthusiastic about
rescue that historical heritage of
Aguascalientes mentioned that the
workshops were for many years a
of the main activities of the
been and for many people for many
the hydrocalids represented a site
where some family members work and
that it was necessary to rescue the
incorporate them into the state’s patrimony
the governor was very clear said I
I need to have a technical opinion of
what is the status on the
pollution and how convenient it is
that the state government acquire that
passive and direct actions to
remedy it and at the time generate
projects to reuse those steps
before that request without much desire to
to be able to confess what we started to initiate
process to see what was the
problematic of the site after six
months
I introduce myself with the governor lord
I explain what was the condition of
contamination
in my opinion at that time
I thought it was perfectly
feasible to do the environmental rescue
this one and he asks me well then of
how much money are we talking about
to be able to do the remediation I calculated
that about 800 million
pesos or cap tells me I have no money
I have the promise of the president who is going to
have oil surplus doctor
start with remediation actions
hoya but I work with the rat
and I’m excited about the cytochrome of
electron transfer doctor
start with the remediation to the park
machinery
there are people there and we need to start
well yes a lot of experience should I
confess what but with much enthusiasm and
with a mandate over
we started doing the actions of
remediation in such a way that good the
idea is to talk about what is what
it was done as it was and how it is
and after 17 years because it’s
precisely in this year that we are
processing before the federal authority the
release of the liability or notice of
conclusion of the remediation in that
tenor I have to tell you how good the
original polygon of the gentlemen
National Railways of Mexico was
96 hectares in that photograph is
you can see that it represented 1.96 per
cent of the surface of the municipality of
aguascalientes that are located at
1.3 kilometers from the city center
that represented at that time a
environmental problem because I had
a certain pollution but also
a very important opportunity for
do the rescue and to be able to
transform this site
I must also tell you that the
old railway workshops
nationals of Mexico in their years of
glory were the biggest workshops
of Latin America provided service
maintenance repair to all
rolling equipment of the system
railways in such a way that they were
the most important in Mexico and without
doubt was one of the activities
fundamental in our is that what
we did good for the first
what we did was to try to identify
what was the main problem of
the different areas
thinking that not all the site was
contaminated that is contaminated with
different compounds that
remediation strategies logically
they had to be different and we have
that implement strategies that
will adhere to three basic principles one
that were technically feasible that
were economically viable and that
they will represent a security scheme
environmental
I do not think we identified good was a
polygon located in the eastern part
where there was a need for power
direct remedial actions in
that first area since there was the
link
to use this area for the
center facilities
rehabilitation for the telethon such
way they gave us instructions for
characterize the area to identify
what was the problem and first
instance to direct actions of
remediation a second polygon was in
an adjacent area more applied to the
part center that are the old
Foundries facilities found
that we had pollution
mainly by lead in the soil of
such a way that for us it was
priority to attend that site one for the
great proximity to the facilities
of the telethon and another because we consider
which represents a risk to health
the third area is part of a plan
strategy that had been developed with
in order to give surplus value to the
site and with the idea of being given
goodwill incorporate the site into a
scheme that was done that by part
of the state government did
initial investments rescue
buildings or areas that represented
great interest and that in this way of
arouse the interest of third parties to
be able to invest in the remediation of
site
in that sense we initiate the
characterization in the remediation of
the southern part what was known as the
area of supply so here as well
all the west edge of the workshops
who needed how we’re going to see
for many years it served as a patio
of maneuvers for the train assembly
Then we start in the actions of
remediation towards the northern part a
part that for many years was seen
as a warehouse for rolling stock that
it had little pollution and
we essentially had the presence of
municipal solid waste already in
more recent times
we started the remediation also of the
North Zone
this pp but thinking mostly about
detonate related projects are
promotion of health
the last stage has been the stage
of remediation and
restructuring area
foundries that is located
in the center part of the workshops very
well stage 1
this is the initial condition of the area
from stage 1
I’m going to present you with a series of
photographs more or less keeping the
same angle in order that you
can see what the evolution was
of those areas the first photograph is
your initial condition
we are talking about the years 2001 2002
and then the remediation actions that
we did in each and the last
photography roughly tries to
illustrate what the current condition is
in this polygon we identify
contamination with fuel oil
fuel oil is a fuel that
used for many years
basically it was to supply
energy to the house of force that was the
original site the energy for all the
complex it was necessary to give
disposition to 35 thousand liters of
fuel oil start the processes and
remediation approximately 25 thousand
cubic meters of contaminated soil
you can see me in the second and
third photographs
the presence of these materials the
removal of this material and can already
see in the last photograph and to the site
remedied and also you can already see the
presence of the facilities of the
comprehensive center telethon observe
you as a change of how I was to
as it is right now there is a radical change
completely by the start of the
remediation actions and reuse
of this space also the zone of
supplies as I said an area
strategic
the idea is that it was the entrance to
complex there is special interest
this zone rescue the area for slaughter
be a place where all the
given rolling stock maintenance
preventive and corrective to the team
they will supply fuels such way
that we have pollution
mainly because he says
We removed approximately 45 thousand meters
cubic of contaminated soil was
necessary to demolish some buildings
because they did not represent interest
historical and yet they presented
pollution this also in a way
important
we rescue the historical heritage
you can see there the round table
the vestiges of the round table the table
round was a semicircular building in
which they entered locomotives
repair this table is recovered
round those vestiges and is part of
historical and architectural element
of the site can see the change
noun in that area
in such a way that right now it represents
entrance to the complex with pride the
western edge was also one of
the important parts of the site
however the rescue of the buildings
especially in buildings that have a
great strength great pride
architectural
one of them is the building of
locomotive repair legislation
Locomotive repair was
built in 1907 was one of the
first buildings of the system
railways at the national level was the
building from where the
first and the only Mexican locomotive
in such a way that in that place was
Repair will repair
the locomotives in their boom times
of the workshops you wish you were staying
repair a locomotive per day it
changed the roofs of san blas plain
structures were cleaned all the
structural elements in such a way
that you can see in this series of
photographs what was the condition
initial of the building is a photograph
of 1935 as they were received in the
building repair of locomotives like
the dismantling of the
roofs cleaning the armours
the cleanliness of the entire structure is
meet cleaning standards of
buildings and what is their condition
current
as you all know the great
most know this building is used
as center conventions or for event
civic cultural and it really is a
pride that attend this kind of
events
I have been in other places and the
people comment on this building by
its structural beauty the western edge
as it is
it was also represented a whole
challenge because because not the big ones
problems that were had with the presence
of the workshops is that it made
transit by its same physiognomy of
polygon made the transit of
north to south and west
in such a way that one of the challenges was
establish road pairs
detailed that will allow to speed up the
vehicular traffic
this and in this way this participate in
the growth dynamics of the
city can see the condition of the
maneuvering yard that was used
for many years to put together
trains it was necessary to remove all this
rolling equipment relocate the yard
maneuvers to remove structures
remove the contaminated soil and started
a remediation process of the area and
of space reuse can
see the roads the road pair that
built in such a way that it has a
different physiognomy
another important challenge was a
set of buildings located in the
part center
these buildings worked like
warehouse warehouse warehouse warehouse
spare parts inside these
buildings
it’s also interesting about these
buildings is currently located the
University of the Arts
in such a way that they can see the change
noun in the condition of this one of
this infrastructure in the northern part
it was also considered strategic
because it was thought a lot that could
be an attraction for the
visitors for people for
hydrochlorides in such a way that
we direct actions for the withdrawal of
Contaminated material
we request permission to semar rap
for the construction of what we call
a cell for the floor deposit
contaminated stopped mentioning that it is
Aguascalientes is the first place where
the semarnat authorizes to deposit soil
contaminated stabilized in a cell
stabilization can see in that series
of images the forest the the sinkhole
the magnitude of the sinkhole was arranged this
contaminated soil
and this cell was precisely located
just below reality
gabriela mistral and you have there was the
Why the road in the missal?
idea is that we do not change land use
because it has restrictions for the use
from the ground this cell
this is the physiognomy of the extreme
north
the initial condition a photograph of
1947
see how it evolves and what the
current condition of this site
as you all know that part of the
polygon of the northern part was thought
from the beginning in including some
project mainly to promote the
health in such a way that for
some time is being built and
It is in the final stage 2008 to
hospital of 2000 the hospital of
medical specialties is the advance in
the structure
we build a second cell this
second cell consumptions in the part
center
we had an excess of material still
approximately 55,000 meters
cubic in such a way that we build
this second cell we deposit the
over contaminated soil and what
deposit is just above this
cell is located a
parking is the photographic series
and it is the current condition very well then
in that way the idea is to illustrate a
very fast very schematic which
is the story behind the
remediation of the rescue of this
site
I must mention that very soon we saw that
rescuing a contaminated site is
inject a new dynamic not
only the site but to all
all adjacent areas
I maintain the thesis that the rescue and
remediation of the workshops
railroads of mexico and the
transformation of the scheme presented
arias was an important boost not
only to the site but to all
of the set of subdivisions neighborhoods
that are around
thank you very much
the laws
