Environmental monitoring, in Spain,is obligatory for all activities included in the standard regulating environmental impact assessment (Appendices I and II of the Environmental Assessment Law 21/2013). Its main purpose is to ensure compliance with all preventative and corrective measures set forth in the environmental impact study (EsIA Environmental and Social Impact Assessment).
The construction of infrastructures or the activities related to the extraction industry are two clear examples of the type of projects subject to environmental assessment and, therefore, environmental monitoring. Thus, depending on where it is located, the proximity of population centres or other key aspects evaluated during the EsIA, the monitoring of air quality may be a measure required by the administration, or considered favourable by the developer.
Dismantling and demolition activities, as such, fall outside the scope of this obligation. That is to say, they are not included in the aforementioned appendices. Nevertheless, depending on the magnitude of the project or the expected impact, the administration may require the project to be subject to environmental assessment.
As can be seen, monitoring plans are not always obligatory. However, Kunak recommends adopting a series of good practices. Measuring air pollution at construction works and demolitions, and providing information regarding air quality, will always be a positive measure in reducing nuisance to citizens.
