It is recommended to carry out the environmental objectives, even though the governmental entities are not requesting them. This in order to achieve a work that meets its responsibility and that in the future is an example for more municipalities.

It is recommended that all workers including those responsible for the works, know the environmental policies that exist for the creation of the company, given that so far only who has that information is the environmental engineer.

Of the created environmental files, it must be implemented, since they will be a lost job, which implies damages that may be irreversible without being taken into account.

In the same way the environmental information must be available, so that the interested ones can review it, since until now I can not find . 

- At this moment, these works are generating environmental impacts that can affect the agricultural production of the neighboring properties, since the increase of the particulate material can affect the physiology of the plants, having an impact on the development, growth and reproduction. In the same way, the lack of fences to contain the sound generates disturbance in the pollinators, since many have to migrate when the noises are strong.

-The biggest problem, which is observed is the ignorance or non-assimilation of the environmental impacts that are generated by the construction work. Although the area was used for agricultural production, there was an ecosystem that was strongly influenced by the pulses of production, but there were species that fulfilled ecosystem services, such as carbon capture, oxygen production and possibly bio- accumulation of heavy metals. Similarly, at the time of construction there is fragmentation and isolation of the population that were shared in all the crops. The processes of vegetation removal and gravel posture generate particles that can affect the fauna.

- Likewise, the lack of signaling is a risk for workers and for neighboring people, given that there is no information to show the danger that people can face when exceeding the permitted limits. At this time, accidents can begin to occur, since there is already an excavation and it is not properly marked. 

-The managers, declares that the environmental impacts identified for the construction of the plant are not very significant, although the entire ecosystem that was previously, was completely modified. The person in charge is justified in the fact that the property was used for cultivation, therefore any modification in the land will not affect the area any more.

-Deamination of waters containing sediments that are a product of construction, to the channel where the population takes water for irrigation. This water does not pass through treatment to be poured.

-In the construction work there is no signaling of any kind, it is not observed which area is destined for the unloading of materials, in the same way the areas where the excavations have already been carried out, there is no signaling that allows to inform all the zones of work, it is also not observed which areas are intended to contain the waste that is being generated. Similarly, the danger that all workers run when approaching construction is not reported.

-They do not have clarity about the disposal of construction waste, despite the fact that Resolution 01115 of 2012, requires that this must be planned in advance in the Management Plan for Construction and Demolition Waste. In the same way before being able to reuse the generated waste, it is required that a classification of all the waste be made.

-The waste generated is not isolated, nor protected from the action of wind or rain.

-None of the workers who were in the construction had protection measures.

-There is no designated area for the workers' rest; During the audit process, it was observed that all workers sit on the edge of nearby crops.

-There are no waste bins, destined for the waste generated by all personnel, which prevents them from being handled properly.

For the treatment of wastewater, it has been proposed to build three treatment trains that operate independently, these trains are composed of a screening, demander, spillway, UASB reactor and a treatment of possible chlorination. The water that will be generated from this treatment plant will be used to irrigate the crops and the sludge generated from the entire process will be delivered to the population so that they can use it as organic fertilizer in their crops (Previso Studies).
