Decision to allow waste water re-injection follows second round of public consultation
The Environment Agency has issued a permit variation to Angus Energy, which operates the Brockham oil site.
This will allow the operator to re-inject waste water, which must be from its operations at Brockham, into one of the existing boreholes on the site.
This decision follows public consultation that took place between 29 December 2021 and 31 January 2022. Having reviewed the responses, the Environment Agency decided to approve the application.
An Environment Agency spokesperson said:
In deciding whether or not to issue this permit variation, the Environment Agency took into account all relevant considerations and legal requirements.
An environmental permit sets out stringent conditions that all oil and gas sites must adhere to. We will not issue an environmental permit for a site if we consider that activities taking place will cause significant pollution to the environment or harm to human health.
It is a condition of the permit variation that the waste water to be re-injected must originate from operations at Brockham oil site. This condition is made clear in the Decision Document and in the introductory note of the permit.
Until the operators have a Radioactive Substances Regulation bespoke permit, they cannot accept produced water from outside Brockham oil site.
