1. Introduction This report is a document produced by Cornwall Council’s Natural Resources Team. It relates to a site visit to monitor compliance with a planning permission and legal agreement for a minerals / waste site under relevant requirements of the Planning and Compulsory Purchase Act 2004.1 Disclaimer It should be noted that apparent compliance with any condition at the time of a site visit by this Authority does not preclude the Authority from instigating enforcement action where any activity being undertaken is subsequently considered to be in breach of a condition or presents a risk of damage or disturbance to the environment or amenity. Any additional site visit required as a result of non-compliance with a planning condition may result in an additional site monitoring fee being levied. Traffic Lights For ease of reference the Authority has adopted a ‘traffic light’ system to illustrate the level of compliance with each requisite planning condition. The colour coding is based on the following criteria;

Green development was considered to be compliant with the relevant planning condition at the time of the site monitoring visit although some minor works may be required.

Amber development was not considered to be compliant with the condition at the time of the site monitoring visit and/or there are outstanding matters which remain to be resolved at this time by the operator or this Authority. Any continued non-compliance or breach of this condition may result in the instigation of enforcement action.

Red development was not considered to be compliant with the condition at the time of the site monitoring visit. Furthermore it is considered that there is an urgent need to remedy this breach due to the potential risk and/or consequences to the environment or amenity. It is therefore concluded that steps should be undertaken without further delay to remedy this breach. Appropriate enforcement action is likely to be expedient should non-compliance with this condition continue.

Condition Number and Description Condition B (1)

Remove the stone from the mineral waste tips with no disturbance to the undisturbed natural ground levels beneath the heaps [except in accordance with any approved working scheme for quarrying of granite as may be approved under the consideration of the forthcoming working plan under the Interim Development Order].

Notes Following Visit The Operator has removed the surface stone from Phase 1 and is now working in Phase 2. The stone recovery works have not disturbed the natural ground level.


The surface dumps shall be removed sequentially as indicated on the attached plan (Drawing No CN16/A) with the Phase 1 removal area edged pink, the Phase 2 area edged yellow, the Phase 3 area edged blue with the final Phase 4 area shown edge orange. Unless otherwise agreed in writing by the Mineral Planning Authority (MPA) there shall be no removal of material from the Phase 2, 3 and 4 areas until Phase 1 has been cleared and restored in accordance with the further details below. Similarly there shall be removal of material from the Phase 3 area until the Phase 2 area has been cleared and has been suitably restored and likewise no removal of material from the Phase 4 area until the Phase 3 area has been cleared and been suitably restored.

Notes Following Visit This condition identifies a phased approach to the removal of mineral deposits alongside a phased restoration programme as shown on Drawing CN16/A on page 9 of this report. Since the previous visit the Operator has recovered the surface deposits from Phase 1. This area has now been completely cleared and the natural ground level remains undisturbed. As required by Condition B(4) this area should now be left to revegetated naturally.

11. Summary

Gonamena is located on Caradon Hill, near the hamlet of Minions in East Cornwall. It is also known as Caradon Quarry and has formerly been known as Silver Grey Quarry.

The quarry was established in the 19th century and was granted conditional planning permission for the winning and working of mineral on 16th June 1948 under an Interim Development Order. This permission was registered as valid on 13th July 1992 and subsequently an application was made by the Operator in 1995 to determine a new scheme of conditions. The application underwent a period of consultation but determination was deferred by mutual agreement of the Operator and the Mineral Planning Authority so that the owner could concentrate of progressing the applications of their other quarries, Lantoom Quarry and Lean Quarry. In the meantime Government guidance indicated that an Environment Impact Assessment may be necessary and as email dated 5th May 2006 the Operator agreed to provide a voluntary Environmental Impact Assessment (EIA). Following on from this a Scoping Opinion was registered on 8th September 2008. At this time the Operator continues to progress with the Environmental Statement and determination of the application remains unresolved. The determination of the IDO application has been extended until 31st December 2013.

In the meantime, works at the site continue under Part 23 Class C Permitted Development Rights, whereby existing mineral deposits which lie on the surface of the site from earlier workings are removed. The approved scheme provides for the mineral deposits to be removed in a phased order, starting with Phase 1, then Phase 2, Phase 3 and then Phase 4. The scheme prohibits the progression into the next phase until the existing phase has been fully cleared and restored.

Since the previous visit in 2012, the Operator has recovered all of the stone from Phase 1 and the site has been cleared back to the natural ground level. This area will now be left to revegetate naturally. Stone recovery has commenced in Phase 2.

There are also permitted development rights to construct a building for sawing granite, although this has yet to be constructed.
