Compliance Regulations

Given the increase in public and EA (Environment Agency) awareness of anaerobic digestion plants, it is important to ensure that compliance regulations are understood and achieved by all anaerobic digestion projects. In many circumstances insurance companies are now looking to ensure that existing plants are compliant both with current regulations and industry best practice.

 

 

Below is a summary of those requirements which should be considered as part of the anaerobic digestion project:

 

 

Pre-Construction Regulations

 

 

• Silage, Slurry and Agricultural Fuel Oil (SSAFO) regulations for slurry storage
• EA requirements:
– All specific requirements including in the planning approval as part of EA approval
– High level alarms for all storage tanks and digesters, automatically stopping all pumped operations when high levels are detected
– Freeboard for enclosed and open slurry stored and lagoons
– Noise and odour requirements
– Ground water inspections chambers (now considered best practice by the EA)
– Bunding, especially when in close proximity to water courses
– Collection and treatment of clamp leachate
– Surface water attenuation and controlled discharge
– Surplus gas burner or boiler to eliminate biogas discharges

 

 

Planning and Permitting:

 

 

AD4Energy offers a wealth of experience in submitting planning applications and advising on Environment Agency (EA) permits. To date we have a 100% success rate with being granted planning permission.

 

 

We can completely manage the full application process and can cover all aspects of the procedure from drawings and design to statements and attending planning meetings if required. These services are available for a range of renewables, not just for anaerobic digestion.

 

 

 

 

Post Construction Regulations

 

 

The following is a list of some of the compliance requirements that should be in place for the safe operation of the anaerobic digestion plant:

 

 

  • DSEAR compliance and Zoning drawings
  • Electrical IEE (17th Edition) wiring regulations
  • Annual Health and Safety inspection of the plant, safety relief systems and high level protection
  • Test certification for all site equipment including tanks
  • Pipework pressure testing certificates

 

 

DSEAR Studies:

 

 

AD4Energy’s experienced in-house team can carry out DSEAR (Dangerous Substances and Explosive Atmosphere Regulations) studies on existing anaerobic digestion plants. With DSEAR our team can analyse the plant for potential gas leaks, review the current process and safeguards, highlight issues and risks, and recommend improvements in line with the latest guidelines as laid out by the Institute of Gas Engineers and Managers.

 

 

The studies will define what areas on site are most at risk of a flammable gas/air mixture building up (known as ATEX zones) and also what types of equipment need to be in or out of these areas. Older sites can particularly benefit from being brought up to date with regulations, as well as newer sites.

 

 

Studies carried out by AD4Energy will be tailored to the particular requirements of the digester and if areas of concern are identified we will work with you to develop cost effective solutions in order to make your site as safe as possible.

 

 

A DSEAR report consists of a written document investigating the substances on site, where and how they might escape, and what precautions need to be taken to prevent ignition sources and gases from coming together. The report will also feature up to date site layout drawings which clearly display where each ATEX zone is, and the severity of the risk they pose.
