In the evening edition of the Official Gazette of the Federation on May 8, 2023, a decree was published amending the Mining Law, the General Law on Ecological Balance and Environmental Protection (“LGEEPA”), the National Water Law (“LAN”) and the General Law for the Prevention and Comprehensive Management of Waste (“LGPGIR”), which came into force on May 9, 2023.
Notwithstanding the scope of the aforementioned reforms, this note only refers to their implications in socio-environmental matters.
- Prohibition of granting mining concessions and carrying out any mining activity in Protected Natural Areas (“ANP”).
The Ministry of Economy and the Ministry of Environment and Natural Resources (“SEMARNAT”) will not be able to issue new mining concessions or environmental impact authorizations (“EIA”) for new mining projects in ANP.
Once the validity of the concessions to develop mining in ANP ends, these concessions will not be extended. Likewise, it would not be possible to extend the validity of AIAs granted for mining projects located in ANP. Therefore, it is recommended that those projects in the exploration or exploitation stage that are located in ANP take this limitation into account.
- Mining concessions that affect an ancestral territory or an indigenous people must be subject to a process of free, prior and informed consultation.
The right to free, prior and informed consultation of indigenous peoples and communities is recognized in Convention 169 of the International Labor Organization, signed and ratified by Mexico. This Convention obliges the Mexican State to respect it for the granting of mining concessions, even when this right was not provided for in the Mining Law prior to the aforementioned reform.
In cases where a mining concession is requested on the ancestral territory of an indigenous people or community, the Ministry of Economy must request the competent authority to carry out a consultation process with the community that could be affected. This consultation process must be carried out before issuing the concession and in parallel with the environmental impact assessment to obtain the EIA of the project.
In our opinion, the way in which the reform regulates this right presents the following problems:
- The processes for obtaining the mining concession and the AIA are not usually carried out at the same time, since, as a result of exploration, it could turn out that mining activity will only be carried out in a specific area and not on the entire concessioned surface.
- It does not consider the right to consent of indigenous peoples and communities, recognized in Convention 169.
- In addition to the obligation to carry out a consultation, the reform establishes the principles and procedures to which this must be subject. Convention 169 establishes that laws affecting an indigenous community must also be subject to a consultation process. Therefore, in our opinion, a law that contemplates an indigenous consultation process could require its own consultation process.
- A social impact assessment will be required for the granting of mining concessions.
The social impact assessment allows us to know the effects that a mining project will have on a community. In addition, this study proposes measures to mitigate and/or compensate for the adverse impacts. These effects include a decrease in income, possible displacements, infrastructure, connectivity and in general any cultural, economic and organizational impact on a community.
The consultation process with indigenous peoples and communities is different from the social impact assessment. Therefore, it is important to consider that (i) if a mining project will affect an indigenous community, both the consultation process and the social impact assessment must be carried out; and (ii) if a mining project will affect non-indigenous people, only the social impact assessment will be required.
- Mining projects must have a Mine Restoration, Closure and Post-Closure Program (“Program”) approved by SEMARNAT.
This Program was already a condition established in the AIA of mining projects, where SEMARNAT ordered project owners to adopt measures for the abandonment of the mining project (for example, slope stabilization, soil restoration and vegetation regeneration).
As a result of the reform, the Program will be a requirement for the granting of mining concessions, the AIA and concessions to exploit national waters.
In our opinion, the requirement to generate a Program from the beginning of the project could be inefficient, since conditions may vary throughout the development of a mining project.
- Current and future holders of a mining concession must present insurance, a letter of credit or another financial vehicle to ensure compliance with the measures for the prevention of social impacts and the Program.
In the case of the social impact assessment, this financial vehicle must be approved by the Ministry of Economy, while the financial vehicle for the fulfillment of the Program must be approved by SEMARNAT.
Current holders of mining concessions must comply with this obligation within 365 calendar days from the entry into force of the reform.
- Ban on granting mining concessions in areas with low water availability.
This ban affects new mining projects that are intended to be developed in areas with limited water availability. It is important to consider that among the areas most affected by drought in recent years is the north of the country, which also represents the area with the largest mineral reserves in Mexico.
The reform does not establish the criteria to determine that an area lacks water. In this regard, the Ministry of Economy could consider the declarations of bans by the National Water Commission (“CONAGUA”), the declarations of emergency or the drought reports that are published monthly by said CONAGUA.
- The transfer of national water concessions for mining activities is prohibited.
Mining companies will not be able to obtain water for mining purposes by transferring a previously issued concession title, so they will only be able to obtain concessions directly from CONAGUA.
It is important to consider that in restricted areas, where the issuance of new concession titles is not possible, a mining concession title could not be obtained by CONAGUA either, which would put the development or continuity of mining activity in these areas at risk.
- National water concessions may be revoked in the event of subsequent events of public interest that cause economic, social, environmental or any other type of imbalance.
This measure affects any person holding a national water concession, regardless of whether they are part of the mining sector or not. The reform to the LAN does not clearly establish what should be understood as social or environmental imbalance, so CONAGUA could act at its discretion to revoke water concessions regardless of whether they have complied with all their legal obligations.
- Prior notification to CONAGUA of the use of working water will be required.
Prior to this reform, the mining concession title granted the right to use the mining water without the need to carry out any additional procedures with CONAGUA. As a result of the reform, it will be necessary to give notice to CONAGUA before using these waters.
- The concept of “water for industrial use in mining” is created and the depth of wells is limited.
To use national waters in the mining industry, a concession must be obtained from CONAGUA that expressly allows water for industrial use in mining.
This type of concession does not allow the construction of wells whose depth could affect the exploitation of water for other uses. Even CONAGUA is prohibited from granting permits for deepening existing wells.
- CONAGUA is prohibited from granting concessions in riverbeds or basins and in its federal zone that have as their objective the final disposal of mining waste or wastewater deposits.
Sometimes mining projects are developed in small riverbeds and in federal zones. However, sometimes these rivers are actually intermittent water flows that meet the requirements to be considered national assets under the responsibility of CONAGUA.
Before this reform, it was common for mining projects to divert or build tailings dams, tepetateras or deposits for non-hazardous mining waste on these runoffs. However, with the reform, CONAGUA would not be able to grant concession titles to occupy these areas.
In our opinion, this provision will affect the development of mining projects in mountainous areas, as it will be technically difficult to find a space with the appropriate characteristics to build mining waste facilities.
- The categories of metallurgical waste and mining waste are created, in addition to establishing new obligations for their generators.
Metallurgical waste is waste from the smelting, refining and processing of metals, while mining waste is waste from the exploitation and processing of minerals. This waste must be subject to a management plan approved by SEMARNAT.
- Waste from mining activities will always be the responsibility of its generator.
The reform does not distinguish between the waste that must be subject to this rule. Consequently, environmental authorities could argue that all waste from mining activity, regardless of its category, will always be the responsibility of its generator, regardless of whether it contracts with authorized companies for its transportation and final disposal.
In our opinion, this provision contradicts the principles established in the LGPGIR, in the sense that the responsibility of a waste generator ends at the moment in which the waste is delivered to a person duly authorized for its transport and final disposal.
