Operators of oil and fuel storage sites need to do more to protect the environment, according to the new report on the environmental standards.

The review looked at 86 sites across England and Wales. The findings show that at 22% of sites there was evidence that measures were significantly below a good level of practice.

The main areas where measures where found to be deficient related to bunds not being leaktight, and bund capacity being below the standard 110% of the volume of the largest tank in the bund. ( A bund is the secondary containment that includes the ancillary equipment associated with a tank as well as the tank itself)
