Thousands of tonnes of lime are to used on a Doncaster area pit tip to combat potential pollution problems.
Planning officers have given consent to spread 32,000 tonnes of powder on Harworth Colliery’s spoil heap to stop pollution of water supplies.
Harworth Estates says the tip surface is strongly acidic and needs to spread the alkaline material to stop acid run-off into drains. Mining operations use lime to adjust the pH of acidic wastewater, removing phosphorus and nitrogen.
The operation will involve thousands of lorry movements over an estimated period of 10 and 12 months, with nearly 400 a month at peak times.
Nottinghamshire County Council’s planning committee granted permission this week.
