YPNPL has constructed a technical ammonium nitrate (TAN) facility adjacent to Yara Pilbara’s existing liquid ammonia plant on the Burrup Peninsula. The TAN Plant is owned by Yara Pilbara Nitrates Pty Ltd, operated by Yara International ASA and marketed by Orica Mining Services Pilbara (OMSP), a joint venture operated by Orica.
The product manufactured at the TAN plant is distributed into the local Pilbara market by OMSP.
The WA Government's Rock Art monitoring program, to which Yara contributed, was last conducted in 2016, so since that time, Yara has contracted independent experts to conduct annual monitoring with the active involvement of Murujuga Aboriginal Corporation. This approach was approved by the Commonwealth Minister for the Environment.
In 2021, the experts published their findings, using data from the monitoring undertaken from 2017-2020, as well as data gathered previously. Their report was presented at the International Council of Museums Committee for Conservation (ICOM-CC) Triennial Conference held (virtually) in Beijing in May 2021, with the paper entitled “Determining decay mechanisms on engraved rock art sites using pH, chloride ion and redox measurements with an assessment of the impact of cyclones, sea salt and nitrate ions on acidity".
