Environment Agency officers found the oil on Seraphim Lagoon, the Bottesford Beck and in wetland channels of Ashby Ville Local Nature Reserve following a call on 22 May 2015 by the TSUK environment manager.
An investigation found that the oil overflowed from an industrial bulk container as oil was being drained from a lubricating tank on the TSUK site.
The firm accepted an obligation to make a donation of £73,000 to Humber Nature Partnership and final plans of how it will be spent are underway.
Elizabeth Cooper, environment officer with the Environment Agency, said: “We work hard to protect people and the environment. In this case, we considered that the Enforcement Undertaking was an appropriate way to sanction the company while creating a benefit for the local environment.”
TSUK has also agreed to take action to ensure that a similar incident does not recur.
The Enforcement Undertaking also requires TSUK to:
- Implement pollution prevention and restoration works
- Review refresher training for staff
- Site improvement works
- Pay Environment Agency costs
“Serious pollution can have devastating effects on rivers, fields and wildlife,” Cooper added.
