AI’s Blackhill processing plant re-emerges at Hillhead, 23 miles away from Straitgate

Since posting in January Blackhill plant to be taken to Hillhead, reconstruction of Aggregate Industries' fixed processing plant - the one that used to blight Woodbury Common in the East Devon AONB and started to come down in December - is now underway at Hillhead near Uffculme.


It is this processing plant that is now intended for each 28.5 tonne load of as-dug sand and gravel from Straitgate Farm. It is this plant that now sits a staggering 23 miles away from Straitgate - a distance which obviously flies in the face of common sense and decency, flies in the face of all the greenwash from AI that "#Sustainability is at the heart of everything we do", and flies in the face of Objective 1 of the shiny new Devon Minerals Plan - which we're told is all about trying to:
secure a spatial pattern of mineral development that delivers the essential resources to markets within and outside Devon while minimising transportation by road and generation of greenhouse gases


AI is currently using mobile processing plant at Hillhead to process the 4 million tonnes of apparently "sand rich" reserves at nearby Houndaller. Even at 300k tonnes a year this reserve will last AI some 13 years or so. But judging by the piles of unprocessed pebbles still sitting stockpiled at Houndaller, the reserve is either not as sandy as we've been lead to believe (and therefore where’s the need for Straitgate?) or the mobile plant is obviously un-suited. On the latter, it wasn't so very long ago that AI said, in its application to quarry the Straitgate resource, that:
New mobile processing plant is to be installed in [Hillhead Quarry] and it is this plant which would be used to process the Straitgate minerals. 3.14
Since then, questions were raised by DCC and by us about the sustainability of processing Straitgate material with mobile plant, and AI has subsequently secured the capital investment necessary to move in the more appropriate fixed plant from Blackhill. In its Reg 22 response to the Straitgate application last year, AI expected that:
the plant will be installed and operational by mid-late 2018... when, subject to planning, mineral would begin to be imported from Straitgate Farm into Hillhead Quarry.
What else is available to AI when Houndaller runs out? AI’s Reg22 response again tells us:
Beyond this, the land 'West of Penslade Cross' which is a 'Preferred Area' in the adopted Devon Minerals Plan (2011-2033) provides a further allocation of mineral reserves of up to 8 million tonnes. If permitted, these additional mineral reserves would extend the life of Hillhead Quarry by a further 20 years, or so.
So you can see why AI would want to site the Blackhill plant at Hillhead. What will be harder for people to see is why the 1 million tonnes (or is it even less now?) of sand and gravel at Straitgate Farm - an uneconomic 23 miles away and less than 10% of what's next-door to Hillhead - is worth the candle?

Meanwhile, for those following events at Blackhill, the photo below shows what the plant area currently looks like. It was due to have been restored to nature by now, but is instead facing an unwelcome planning application from Clinton Devon Estates - as posted in Why does quarrying have such a bad name? Take a look at Blackhill and Objections mount for CDE’s planning application for Blackhill Quarry. Bear in mind, DCC has agreed an extended restoration timetable with AI:
End May 2018 - plant will be completely removed from site. June 2018 commence removal of all concrete bases and ancillary buildings. End 2018 site restoration.
