ADOC 2021 SUSTAINABILITY REPORT

WASTEWATER

We manage our effluent discharge in accordance with Federal Law No. 24 of 1999 and relevant ADNOC HSE Standards
(2020). Effluent released to the municipal sewerage system in Abu Dhabi from the onshore facilities is in compliance with the
Abu Dhabi Sewerage Services Company (ADSSC) regulations, while wastewater discharged to the marine environment from
the offshore operations is in compliance with the ADNOC HSE Standard for Standard Limit for Effluent Discharge to the
Marine Environment and the Abu Dhabi Quality Conformity Council (QCC) Environmental Specifications for Land-Based Liquid
Discharges to the Marine Environment and Ambient Marine Water and Sediments Specifications. We also adhere to the relevant
Environment Agency Abu Dhabi (EAD) guidelines for working within the MMBR.
SPILLS

We are dedicated in preventing and minimizing the number and volume of hydrocarbon spills within our operation fields and
facilities. We mitigate the risk of spills through strict procedures for handling hydrocarbons, chemicals, and waste, through regular
maintenance of our assets in accordance with our asset integrity management system. We have a dedicated Spill Response
Procedures and resources for each of our operating fields and facilities (further information is provided in Chapter 4). There
were no recorded major spills in 2021.

WATER WITHDRAWAL

We adopt conservation principles which encourage the minimization of water usage wherever possible. Withdrawn water
comes from municipal water suppliers, produced water (water produced as a byproduct of oil and gas extraction) and surface
water. Due to our continuous focus on water minimization aspects, a 4% decrease in water withdrawal levels were recorded in
2021 compared to the 4% increase in 2020. We do not produce desalinated water nor withdraw water from any water stressed
or freshwater sources in 2021.
