Since March 19, 2014, the Port Authority has signed an Agreement with the Autonomous City for air quality monitoring.

On the basis of said Agreement, in December 2018, an Environmental Quality Control and Surveillance Station, as well as another mobile as well as the forecast, for a future SOx analyzer has been set up on the dock Spain.

On the other hand, the safe handling of hydrocarbons that may contain hydrogen sulfide is an important issue for the industry, to the point that ISO 8217: 2017 has been revised and has specified a maximum limit of H2S content for marine fuel in the liquid fuel of 2.00 mg H2S / kg fuel (2.00 ppm).

Therefore, the Port Authority is working on the normal application of reducing the content of hydrogen sulfide in fuels.
