Miller Homes fined £100k for pollution offence

20 May 16 House-builder Miller Homes has been fined £100,000 over a pollution incident on a site in Huddersfield.

At Leeds Crown Court this week the company admitted one environmental offence for an unauthorised discharge of water, containing silt and sediment, from its  construction site at Lindley Park into a nearby watercourse that runs into Grimescar Dyke.

The incident took place in November 2013.

Flannery Civil Engineering Ltd was fined £9,000 by Kirklees Magistrates’ Court in March after admitting a similar charge for its involvement in the same incident.

The Environment Agency prosecutor told the court that the polluted water should have been managed on the construction site, and that neither company had permission to discharge silt water from the site.

Miller Homes contracted Flannery to construct four storage lagoons in order to reduce the risk of flooding downstream. Straw bales were used on the outflow of the lower lagoon to prevent silt from leaving the site.

But following heavy rainfall in November 2013, the lower lagoon filled with water, and Flannery removed the straw bales to allow it to drain. With the bales removed, silt water ran directly into the watercourse, affecting water quality.

A member of the public reported the pollution incident to the Environment Agency, which sent an officer to investigate. He found that the watercourse was running a dark brown colour, and traced the source back to the development site.

The officer also saw that the straw bales were situated at the side of the lagoon, no longer filtering the discharge. Water entering the top lagoon was clear, but the water leaving the bottom lagoon was cloudy.

In mitigation, Miller Homes said that it immediately improved the lagoon system following the incident. It said that its directors had been ‘apoplectic’ that the problem had not been reported to the Environment Agency or even themselves at the time.

A spokesperson for the Environment Agency said after the hearing: “Environmental permitting laws exist to protect the environment and local communities from harm. This case shows how important it is that construction and other industrial companies adhere to the regulations to ensure that their activities do not pose a risk of pollution.

“Miller Homes should have had more effective water management systems on the construction site to prevent the silty run-off from affecting local watercourses.”
