PERU LNG 2021 Annual Report

ANNUAL REPORT PERU LNG 2021 CHAPTER 6 WORKING WITH RESPONSIBILITY AND COMMITMENT 2021 53 PERU LNG'S PLANT TAKES WATER DIRECTLY FROM THE SEA (294 640 CUBIC METRES IN 2021, SLIGHTLY MORE THAN THE PREVIOUS YEAR). The water purification system has been covered by a Drinking Water Quality Plan (PCC-I) authorised by the Environmental Health Bureau (DIGESA) since 2016, which was renewed at the end of 2021, meaning that PERU LNG ensures that it meets quality, health and environmental standards, reducing any effect on its surroundings to a minimum. Despite the state of emergency resulting from the COVID-19 pandemic, in 2021 self-sufficiency in water and strict quality controls meant that high-quality drinking water was always available. Furthermore, as part of its environmental commitments the company continues to treat all waste water from camps and offices in the plant (40 071 cubic metres, which is 32% less than the previous year), in a domestic waste water treatment system using activated sludge. All of the treated waste water was used to irrigate green areas and to suppress dust on unsurfaced roads within the plant; in other words it was used and not discharged into any water body or into the sea. Treated waste water is monitored frequently and all test results meet the environmental standards contained in the environmental management tools (IGA) approved by the competent authority.
