**5. Conclusion**

The recent publication of the Global Industry Standard for Tailings Management prompted some modifications or adjustments to the main MAC reference documents, such as the Tailings Guide "see [2]", but these changes did not have a major impact on the model originally proposed in the article published by authors in the journal Mine Water and Environment entitled 'Integrated Risk Management in Mine Tailings Facility' "see [1]". In a way, however, the Standard induced a different view on the applicability of ISO standards to tailings management, in particular the ISO 9001 standard.

In our previous article, we considered as a differential the use of requirement 8.3 of the ISO 9001:2015 standard, as one of the tools for integrating MAC guides to ISO standards, although the focus was on the design and development of products and services. In line with our purposes, by identifying some works edited by TC 176, the committee responsible for the work on ISO 9001 at ISO, we identified recommendations for using this requirement for process design, as can be seen in the document ISO 9001 Auditing Practices Group - Guidance on: Design and Development Process, "see [13]".

In addition, through the Standard, it was possible to increase the scope of the applicability of ISO 9001, including, in this text, issues associated with the context of the organization, risk mentality and quality plans, which were not previously considered.

Finally, the interpretation of the Standard led us to conclude that its design did not take into account the current models of management systems, making it repetitive in some of the established requirements, and we believe it is appropriate that, in a future revision, the Standard becomes be organized according to the superior structure of Annex SL, used in the ISO standards of management systems and based on the PDCA cycle.
