Officials in Northern Ireland are planning a series of Brexit outages, including fuel shortages, which could lead to motorists being confronted with 15 liters of fuel per week.
Senior officials are very much concerned with contingency planning on unlikely scenarios, but they need to be prepared for a range of contingencies.
A number of staff in key roles were thought to be involved in war-style exercises in which they were asked to look at different scenarios, including trucks full of living borderline chickens and public transport that come to a halt.
According to the sources, fuel shortage is also considered as a possible result of Brexit. The economic authority downplayed the possibility of fuel ration.
A spokesperson said, "The Economic Division has political responsibility for NI energy sectors, including fuel, and has been working with industry for many years to develop contingency plans. The routine fuel response plan contains a number of measures that can be used depending on the severity and extent of the effects of fuel shortages. However, there is no indication that such a fuel emergency will occur with respect to Brexit. "
However, one official said Belfast Live was being "taken very seriously". He added, "They organize us as if we were preparing for a military campaign with command structures.
"The amount of fuel is ridiculous, if it were not so serious. There was a historical problem when dodgy diesel was traded across the border. Can you imagine the field day smugglers would have had if gas had rationed and demand for fuel had risen?
"The people here will not give up their cars for public transport to find fuel. Let's hope that emergency plans never have to go into effect. "
Late last year, the civil service director in Northern Ireland confirmed that he had approached all 23,000 employees who were looking for "volunteers" to respond to Brexit in an emergency.
David Sterling said preparations for NICS include planning a no-deal brexit and a worst-case scenario that includes "persistent and widespread disruptions".
Mr. Sterling asked for volunteers to work in the NICS "leadership, control and coordination structures".
He said that "new temporary structures" might have to be implemented around the clock.
Mr Sterling added, however, that the plans do not mean that a "no-deal exit is now the most likely outcome, or that it will even be necessary to make those arrangements".
He told the BBC, "This is just the next step in preparing our exit day plans."
Officials expressing their interest in NICS emergency preparedness were asked to indicate whether they would be willing to work in shift work and on weekends.
The NICS plan includes a central hub that will coordinate Northern Ireland's strategic response to Brexit.
The hub is operated jointly by the Northern Ireland Office and the Stormont Executive Bureau and may need to be manned around the clock.
