 requirement for all of its mining sites and facilities. The main requirements of the law are related to the execution of measures to obtain the physical and chemical stability of the mining site and its facilities, as well as the protection of life, health, safety of people and the environment, along with the estimated cost to implement such plans. The mining site closure plans are approved by Sernageomin and the corresponding financial assurances are subject to approval by the CMF. In both cases, SQM has received the requisite approvals. During 2020, any required closure plans were updated and presented to Sernageomin in accordance with required deadlines. In 2021, approvals of the updates of the closure plan for Tocopilla and Pedro de Valdivia sites were renewed, while in 2022, approvals of the updates of the closure plans for the Salar de Atacama, Lithium Chemical Plant, Coya Sur, Nueva Victoria and Pampa Orcoma were received. Finally, during the year 2023, the update of the closure plans for the Pampa Blanca and María Elena sites was approved.
We continuously monitor the impact of our operations on the environment and on the health of our employees and other persons who may be affected by such operations. We have made modifications to our facilities in an effort to limit any adverse impacts. Also, over time, new environmental standards and regulations have been enacted, which have required minor adjustments or modifications of our operations. We anticipate that additional laws and regulations will be enacted over time with respect to environmental matters. There can be no assurance that future legislative or regulatory developments will not impose new restrictions on our operations. We are committed to continuously improving our environmental performance through our Environmental Management System. 
Since 2020, we have participated in voluntary ratings such as Ecovadis, international certifications such as Responsible Care from the Chilean Chemical Industry Association, Protect&Sustain from the International Fertilizer Association, ISO 14001, ISO 45001 and ISO 50001, and the IRMA Standard Assessment Audit, to promote responsible mining.
During 2024, the Port of Tocopilla was re-certified by Responsible Care, achieving level 1 certification. Similarly, this year, the Nueva Victoria mine was re-certified, again achieving level 1.
In terms of port environmental management, the Port of Tocopilla improved its performance in Ecoports of the Port Environmental Review System (PERS), raising its compliance percentage from 90.57 % in 2022 to 92
