Natural Resources Wales has served a formal warning and an enforcement notice on the Bryn Compost waste treatment facility in Gelligaer.
This follows a breach in its permit conditions which resulted in strong odours affecting people living in both the Gelligaer and Nelson areas.
After concerns were raised by local people, officers from Natural Resources Wales carried out an investigation at the site which found that the company was exceeding the volume of waste it is permitted to keep on the site per year.
This increase in waste is likely to have been responsible for in the increase in odour problems at the site.
The company now has to make sure it does not exceed its waste input limits over the next 12 months to so that this type of breach does not happen again.
In addition to this, Natural Resources Wales is also stepping up its regulation of the site to make sure the company is doing everything it can to reduce odour problems at the site and its impact on the community.
Gareth O’Shea, from Natural Resources Wales said:
“We regulate sites such as Bryn Compost to make sure that they are complying with the conditions of their permit and their activities are not affecting the quality of life for local people.
“Since we granted the permit to Bryn Compost in 2005, we have regularly reviewed their activities and enforced a number of improvements to operations at the site.
“We continue to monitor operations at the site very closely and will be increasing inspections to make sure these latest improvements are made to reduce the impact of odour on people living in the area.”
As part of the enforcement notice the company is required to:
- Review how it monitors the condition of the waste being processed to ensure oxygen levels are kept at levels to prevent anaerobic conditions which can lead to offensive odours.
- Maintain the restriction on the volumes of food waste inputs (6000 tonnes) into the in-vessel composts as this has helped reduce the risk of offensive odours.
In addition to this Natural Resources Wales is:
- Increasing audits of site operations and procedures.
- Improving incident response procedures to quickly identify failures in operations which breach permit conditions and cause odour problems.
