Natural Gas

Volume 503: debated on Thursday 7 January 2010

To ask the Secretary of State for Energy and Climate Change for what reasons the oxygen specification threshold of natural gas was set at 0.2 per cent.; and whether his Department has made an estimate of the effect on the level of use of natural gas of raising that threshold to three per cent. (305182)

[holding answer 8 December 2009]: This limit is set in the Gas Safety (Management) Regulations 1996 (SI 1996 No. 551), at schedule 3/part 1. Those regulations were made, by the then Department of the Environment, on the advice of the HSE. Subsequently the then Department for Business and Regulatory Reform consulted on future arrangements for Great Britain’s gas quality specifications, and concluded that there was not a case for seeking change to the GS(M)R. Gas quality, and the process for seeking flexibility under the current statutory arrangements, is again discussed in a document just published by my Department, entitled “Biomethane into the Gas Network: A Guide for Producers”; this is available at:
