It has been announced that as of 1st October 2016, the OGA (Oil and Gas Authority) will be established as an independent regulator by the UK Government and receive new powers that will mean it can act with greater speed and flexibility to drive investment, support jobs and further UK’s competitive edge in the oil and gas industry.
Planners in Cumbria have given the go-ahead for two new vaults at the UK’s Low Level Waste Repository (LLWR), along with an extension to a third vault.
The LLWR was opened in 1957 as the only UK location for the disposal of solid waste containing low levels of radioactivity. It provides an essential service for NDA sites as well as other industries that produce low level waste(LLW). More than £100 million has been invested in the site’s infrastructure over the past decade to maintain it as an important national asset.
A mine waste water treatment scheme in north-east England is removing over 98% of the metals from drainage from old ironstone mines which feed into Saltburn Gill.
In 1999 a large mine water outbreak occurred which flowed into the gill quickly turning the stream a bright orange colour. This severely impacted the fish and river insects and smothered the stream bed in the gill and Skelton Beck. It also affected the bathing water quality on the beach.
Following initial work, the Coal Authority was asked, in 2013, to develop and build a mine water treatment scheme because of our expertise in treating water at historical mining sites. The treatment scheme works by using four lagoons, with cascades and a drying bed, to remove the iron from the raw mine water. The mine water is pumped to the top of aeration cascades and over a period of two days it flows down through each settlement lagoon where the majority of the iron settles. The sludge is then transferred through underground pipes from the bottom of the lagoons through into the drying bed where it is collected and removed. The treated water then passes through a polishing reed bed that acts as a further filter.
