• Make cost and time savings

Simon Talbot

Managing Director, GGS

• determine the true subsurface gas regime;
• predict how this may change in the future;
• assess the ground-gas risks, and
• manage those risks

Steve Wilson

Technical Director, The Environmental Protection Group Ltd (EPG)

• CIRIA C735: The process of demonstrating that the risk has been reduced
  to meet remediation criteria and objectives based on a quantitative assessment of remediation performance;
• The need for all installments to have some form of verification to be built into the process;
• Ensuring verification is proportionate to:
• the risks from the site, and
• the experience of the installation operatives
• C735 Decision Structure
• Complexity of design;
• No. of plots/buildings;

The Contaminated Land Regime (CLR) under Part 2A of the Environmental Protection Act 1990, Guidance is intended to explain how local authorities should go about deciding whether land is contaminated land in the legal sense of the term. This presentation will focus on the issues Local Authorities face in regards to Ground Gas and how they can overcome the challenges and barriers whilst complying with legislation.

• The largely unknown High Court Action in 1988 involving landfill gas and the construction of a new housing development by a major house builder;
• The extent of our knowledge at the time;
• How landfill gas issues have morphed into ground gas issues and how relatively little we know today;
• Finding the right balance between scientific rigour and engineering pragmatism; and
• Fracking: Shale Gas/Coal Bed Methane a reflection on the Government’s likely future direction.
