Natural Resources Wales (NRW) has refused an environmental permit application for an on farm anaerobic digester near Jeffreyston, Pembrokeshire.
NRW has refused the permit because of a history of pollution incidents at the site.
After several incidents, NRW believes there is a likelihood that the applicant would fail to operate the site in accordance with the environmental permit.
The applicants planned to install an anaerobic digestion plant that would have been used to break down organic farm waste into fuel.
John Wheadon, Permitting Service Manager for NRW, said:
“Whenever we issue an environmental permit we have to make sure that the applicant can operate in a way that minimises the impact on people and the environment.
“We will only issue a permit if we are confident in the individual or company’s ability to do this.
“Having thoroughly assessed this proposal we believe granting this permit would likely lead to more pollution incidents on site”
