A MAIN road was closed for nearly two days after the first of two leaks in one day at Shell's Stanlow complex.
The first incident at 9am on Wednesday involved a spillage of about a tonne of crude oil.
This forced the closure of Oil Sites Road, the private road that runs through the site, until 3.35pm on Thursday.
The second incident came at 11.40pm on Wednesday when there was a leakage of about one tonne of Iso-propyl alcohol.
Shell spokesman Edward Brady said of the first leak: 'It occurred when one of the oil pipes failed but it's now been repaired.
'Some of it went into the River Gowy but we sucked it up immediately. The road had to be closed for safety reasons because our emergency response team used several vehicles during the clean-up process.'
Ellesmere Port firefighters attended the incident but their help wasn't needed.
Mr Brady said the leakage of Iso-propyl alcohol later on Wednesday was confined within the site's effluent system.
He explained there had been no impact on the environment, and no injuries were reported.
He added: 'The incident was again managed by the site's emergency response team.
'The county fire service was called in as a precaution and as part of our normal procedure. They were stood down after half an hour.'
Mr Brady said investigations into both incidents would now be held.
