Safety Monitor Calculations

I had a response from the Health and Safety executive today about the Safety Monitors. They said that National Grid are not recalculating them. That does not seem sensible. 45 mcm is not much of a safety cushion if we enter into emergency mode. 200 mcm (the total of the Long and Medium term) is more reasonable.

The weather forecasts are pointing to particularly cold weather next week still. A very small amount of gas appears to be coming from Long Term Storage, (1 mcm). That, however, could be some form of recording error.
