Existing Operations

Gypsum extraction is currently taking place centrally within the site.

Operations are currently progressing north in the direction of Fernwood and Balderton (see aerial image, below).

Under the current planning permission, these operations can continue until 31st December 2027, with the final restoration to be completed by 31st December 2029.

Based on the current predicted rates of extraction, it is anticipated that the existing permitted gypsum reserves will be used up by 2024/25. To ensure we have access to high-grade gypsum beyond this date, we are submitting a planning application to extend the quarry to the south.

British Gypsum - Bantycock Existing Operations

What are we proposing?

The reserves at Bantycock Quarry are currently expected to be used up by 2024/25.

British Gypsum - Bantycock ProposalTo ensure that we continue to have high-grade gypsum to supply Jericho Works and our sites across the Midlands, further reserves are needed.

Geological investigations have found that there are additional gypsum reserves to the south of the existing planning permission boundary. We will be seeking planning permission from Nottinghamshire County Council for the following:

  • A southern extension to Bantycock Quarry
  • Extraction of up to five million tonnes of high-grade gypsum
  • Retention of existing processing area and site access road
  • Continuation of operations until 2044
  • Amendments to the approved restoration scheme.

Environmental Assessment (Overview)

As part of the planning application we will carry out a detailed environmental assessment of the potential impact of the quarry extension.

This will include traffic, soils and agricultural quality, archaeology, water, landscape and visual effect and ecology. We also assess noise, blasting and dust and include a detailed proposal for restoring the land once the quarrying has finished.
Traffic: no changes are proposed to existing traffic routes or numbers of vehicles.

Soils and agricultural land quality: detailed surveys have been undertaken to identify soil type and agricultural land quality.

Archaeology: recording has been ongoing for more than 15 years to ensure relics and important historical features are preserved/recorded.

Water: we have looked at possible effects on groundwater resources and surface water flows.
British Gypsum - Restored Land
Landscape and visual: we have examined any changes to landscape character and visual effects from public vantage points. We are designing our operations to minimise visual impacts.

Ecology: habitat surveys have been undertaken to identify if any protected species or notable habitats are present. British Gypsum - Ecological

Noise

We adopt best practice to control noise from our site to minimise impact upon local communities.

British Gypsum - Decibel LevelsLimits: the quarry would continue to operate below 55 decibels (measured at the site boundary).

Noise management measures include:

  • Landscaped screening mounds
  • White noise reversing beepers
  • Noise monitoring surveys at locations agreed with Nottinghamshire County Council.

Blasting Overview

As operations progress southwards in the new extension area, each blast will continue to be controlled by strict planning, environmental and safety controls:

  • Only take place between 1:30 – 3:30pm Monday to Friday
  • Designed to be within limits permitted by Nottinghamshire County Council
  • Monitored at pre-determined locations agreed with Nottinghamshire County Council
  • Controlled by Quarries Regulations
  • Be supervised and only carried out by highly qualified personnel.
Please visit our extraction page for more information on the whole extraction process.

If you would like to view a blast in person, please get in touch with us at bantycock@saint-gobain.com to arrange a visit

Example of a typical blast

Blasting (Ground Vibration)

When blasting takes place, a small amount of energy is generated in the form of vibration waves.

British Gypsum - Ground WaveThese travel through the ground and may be felt inside properties. Nottinghamshire County Council has set a ground vibration limit for all blasting that takes place at Bantycock (see table below).
British Gypsum - Ground VibrationBased on extensive research from around the world, this level is well below that which would cause structural damage to properties.

How humans respond to ground vibration depends on a number of factors, such as: age, health, physical attitude and previous exposure.

Humans normally become aware of ground vibration at levels of around 1.5mm/s, although this can be as low as 0.5mm/s.

Blasting (Air Vibration)

When blasting takes place, energy is also released in the form of air vibration (known as air overpressure).

British Gypsum - Air Vibration There is no known evidence of structural damage having occurred in the UK as a result of air overpressure levels from blasting associated with mineral extraction.

Weather conditions may cause air overpressure to produce different effects from similar blasts:

  • On a clear day, the pressure travels upwards, but low clouds will cause the air wave to reflect and be felt at a greater distance
  • Wind can also result in a 10 – 15 decibel increase in sound level downwind, compared with levels in cross or no wind conditions.
British Gypsum - Air Overpressure Blasting can cause a small change in air pressure, which may be noticeable inside properties.

The weakest part of most buildings exposed to air overpressure are windows. Those that are poorly mounted have the potential to crack at 150 decibels (dB).

Air overpressure levels from a quarry blast measured at properties are around 110-120 dB. This is 30 decibels below the limit required for cracking poorly mounted windows.

Dust

We adopt best practices to control dust from our site to minimise impact upon local communities.

British Gypsum - Dust ControlDust management measures include:

  • Water applied to haul roads
  • Continuous visual daily monitoring by site supervisors
  • Processing plant fitted with suppression sprays
  • Modern low emission fleet of vehicles
  • Wheel-wash for all vehicles exiting the site
  • Monthly dust monitoring.

Restoration Scheme

We will progressively restore the quarry as areas become available following the completion of gypsum extraction operations.

The restoration concept plan (below) is how we see the site finally looking when extraction is completed in around 24 years’ time.

Footpaths will be created in various parts of this restored area.
