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

after the island
