Site Specific External Emergency Plan – V1.1 Official 2
Introduction This is the External Emergency Plan (COMAH) for the Newlyn Downs Explosives Storage facility. The plan details how we will respond to an off-site incident at the site, and will work in conjunction with the sites own on site safety and emergency plan; which will be invoked if an incident occurs, on or off site.
The plan will be validated and regularly exercised by the site operator and responding organisations, and will be maintained by Cornwall Council Resilience & Emergency Management.
The private and business addresses within the defined Public Information Zone (PIZ) have received consultation letters and details of where they can access the public version of the plan, which contains the recommended actions on becoming aware of an incident relating to the Newlyn Downs site.
Pre-Warning information to public within PIZ Redcliffe International provides members of the public living or working within the PIZ with information on safety measures at the establishment, and on the requisite behaviour in the event of a major accident at site.
The immediate actions that should be taken by persons living or working in the PIZ are “GO IN, STAY IN, TUNE IN” details below: (a) Go/stay indoors and close all windows and doors; (b) Switch off all systems which may draw in air from outside; (c) Remain indoors and await further instructions; and (d) Switch on the local radio station for announcements.
Preface Redcliffe Explosives Storage Depot at Newlyn Downs, Cornwall occupies a 12 acre site and has security approvals from the Health & Safety Executive (HSE) and Devon & Cornwall Police. This is one of the most advanced secure magazine sites in the UK.
It offers secure and licensed storage for 181.3 tonnes of class 1.1 and Section 5 restricted explosives or weapons, offering consolidated shipment of bulk explosives and just-in-time deliveries. • Licensed by HSE for 181,000 Kgs NEC class 1.1 • 5 mounded magazines each 15.75 x 6.7 x 3m • 1 Hornsby and Goodwin detonator store • Total useable floor space 5,500 Sq. ft. per magazine • Approximately 200 pallets per magazine (double-stacked) • Secure fenced site • Fitted with alarm and security systems approved by Police Explosives and Firearms department • Firearms Act Section 5 storage is available.
Site Specific External Emergency Plan – V1.1 Official 3
The site is used to bulk store a range of packaged explosives as substances, preparations and/or explosive articles. Materials are transported & stored as classified by the HSE/ESTC and detailed in Appendix 3.
The explosives storage facility consists of six above ground magazines, comprising five concrete monolith construction magazines, with entry to each of these magazines being through a single adit secured with steel doors. In addition, there is a small single Hornsby and Goodwyn type wooden lined steel container, currently used for the storage of detonators. Each building is licensed for the storage of explosives within Hazard Types 1, 2, 3 & 4 subject to the normal explosive compatibility rules. There is no licensing provision for the processing of explosives on site. In addition to the licensed storage magazines, the site includes a welfare facility, and a non-explosive steel shipping container for the storage of the forklift truck (FLT) and other site assets. The site occupies a total area of approx. 4 hectares.
There is CCTV on site and this is managed and monitored by Securiguard.
The single-point access to the site is via a privately-owned single track road, which is shared with a small car repair garage, windfarm generators and the neighbouring farmer.
The lane leads from the B3285, with no vehicular route beyond the explosives storage site, although it is designated for public access as a footpath. The closest site of regular activity is a garage and car repair workshop at the junction of the B3285, which has approximately three people working on a daily basis, and is sited beyond the safeguarding Inhabited Building Distance (IBD).
The adjacent windfarm is owned and controlled by Scottish Power, and has a permanent staff of 3 people who may be present on a daily basis at their control building, which is also sited beyond IBD.
The surrounding farm land is given over to a mixture of arable crops and animal grazing use.
The village of St Newlyn East lies approximately one mile to the north, and has a population of about 1635 (source: 2011 census).
There is a miniature heritage steam railway (Lappa Valley Steam Railway) and golf course 0.6 miles at its closest point, to the north-east, and is operated as a tourist attraction. The entrance, car park and visitor buildings for this railway are located at 1.75 miles from the site. Again, this is situated beyond the safeguarding IBD.
The nearest town is Newquay at 7 miles distant. To the north, south and east of the storage site, the land has been designated as a Special Area of Conservation, and a Site of Special Scientific Interest, owing to the presence of Dorset Heath (erica ciliaris) growing.
Site Specific External Emergency Plan – V1.1 Official 4
Risks There are a number of scenarios covering the major risks to the site and these are categorised at Appendix 2.
For each scenario a risk assessment has been undertaken for what might be produced in terms of volume and constituents of gases produced, and how they would dissipate once released.
Concrete debris from a catastrophic blast covering an area up to 500 metres (mainly farmland) is anticipated. There is a public footpath running to the rear of the site, which is used fairly infrequently and the walkers and local farmers are considered transient for the purposes of this plan.

SECTION 1: ACTIVATION Plan Activation In Cornwall, the Redcliffe International Ltd Newlyn Downs storage depot is unique in that it falls under the explosives element of the COMAH Regulations, so the response arrangements differ to other Upper Tier COMAH establishments.
Categories of declarations There are three defined categories of emergency declaration that can occur at Redcliffe International Ltd Newlyn Downs Depot. The different categories allow for a proportionate response to the situation, ensuring that all necessary parties are notified: (See diagram below) 1. Site Incident 2. Off-Site Incident (non-COMAH) 3. Off-Site COMAH Incident
The plan will be fully or partially activated without delay when the following has been declared: • Off-Site Incident (non-COMAH) • Off-Site COMAH Incident
This plan will be activated without delay when: • A major accident occurs; or • An uncontrolled event occurs which could be reasonably expected to lead to a major accident.
Responsibility for activating the plan: The identification and assessment for activating the plan is primarily the responsibility of the Site Main Controller. Dependent on the incident this may be in liaison with category 1 responders attending the scene.
Should there be no-one on site at the time of an incident then any of the responding “blue light” services may request activation of this plan.
Note – during unmanned hours site staff would be notified by CCTV Company if a blast occurred, via the linked alarm.
If the notification comes from a member of the public into the emergency services the following actions will take place: 1. Confirmation call to other blue lights 2. Deploy to RVP 3. Contact site for information 4. Make an initial assessment
Decide category, and Force Incident Manager will instigate the necessary notification cascade.

They will pass this information to Police and Ambulance Service when they make the confirmation phone calls.
Public Information Zone The Competent Authority (Health & Safety Executive) has determined the PIZ is up to Vulnerable Building Distance, which is Class E distance on the building schedule which equates to the purple line on the safeguarding plan.
Made up of properties in the areas of Fiddler’s Green and St Newlyn East. The PIZ also covers the following businesses: • Scottish Power Wind Farm – Carland Cross • Farms • Residential Home
Map of the PIZ (site boundary, HSE outer zone and PIZ)
Initial Response Site • Activating Site Warning Siren • SMC to notify emergency services via 999 • SMC to don tabard to identify themselves to emergency services • Site staff to evacuate and locate themselves at: o 1 member of staff to RVP car park to brief and support Emergency Services and; o 1 member of staff to be available to the Tactical Co-ordination Centre, Truro (by phone if not in person). • Notify Redcliffe Operations Director Site Specific External Emergency Plan – V1.1 Official 15
• Redcliffe will provide (locally or remotely) detailed information to emergency responders on the inventory, explosives and their explosive effects. • Staff at RVP will have access to MSDS, any CCTV and inventory. • Media – Spokesman from Redcliffe Headquarters at Nottinghamshire.
During – Public Messages The Police FIM will contact the duty Police Press Officer to request the LRF Media Plan is activated and the appropriate public safety messages are put out via radio, TV and social media platforms. An aide memoire to assist in providing an overview of the on and off-site response within two hours of the declaration is included at Appendix 1. Pre-prepared media messages can be found at Appendix 4 (Content removed from public consultation).
Responding Organisations All organisations and agencies will respond using the roles and responsibilities as outlined in the section below.
Emergency Route Information Safe Approach Routes Due to the width of the surrounding roads it may be necessary to implement a one way traffic management system. A dynamic assessment will be made at the time. Once off the main road and past the car repair workshop the private lane is single track.
Access to Site The emergency services would conduct a dynamic risk assessment, based on FireMet details and information on the situation (either from site staff or via the CCTV Company) and decide where the most appropriate location to co-locate is.
Options for RVP/FCP and Marshalling Areas Suggested RVP and marshalling areas given below should be confirmed on the day and used with the permission of the owner/operator: (Content removed from public consultation).
Traffic Points The traffic diversionary routes should the A30 need to be closed, have been determined as: • A30 between Carland Cross and Chiverton Cross - this takes traffic to the north of the site via Goonhavern and Quintrell Downs. Should an incident occur and the wind direction is from the south, a decision would need to be taken as to whether it is safe for drivers to follow this route.
Site Specific External Emergency Plan – V1.1 Official 16
Key Actions Site Initial Command Structure Where possible, the Site Main Controller will initially assume overall responsibility for the incident. The senior officer from Cornwall Fire & Rescue Service will assume this role when they arrive on scene/at the RVP. In circumstances where the Site Main Controller is unable to assume initial responsibility (i.e. because site staff have been involved in the incident or it occurs during unmanned hours), the first responders would assume responsibility.
Ongoing Response Shelter A major accident would likely involve fire, explosion, debris and possible noxious gas cloud arising from those products of combustion of the material. The short duration event would cause serious on-site damage, but not restricted to an area inside the boundary.
If a decision is made to evacuate, pre-identified shelters would be activated in line with the Shelters database held by Resilience & Emergency Management.

Public Health England Consider the requirement to declare an emergency in accordance with the Local Resilience Forum Combined Agency Emergency Response Protocol – Section 5.5.3.
Public Health England (PHE) is an executive agency of the Department of Health. PHE provides an integrated health protection service to ensure that the public are protected from threats to their health from infectious disease and environmental hazards such as radiation, chemicals and poisons.
PHE Centres (PHEC) provide a 24 hour nationwide integrated public health service delivering expertise, information and intelligence to public health teams based in Local Authorities and the NHS tailored to local needs. PHE’s Centre for Radiation, Chemical and Environmental Hazards (CRCE) is a source of specialist advice and operational support through PHEC’s, providing expert advice on the public health risks of chemicals in the environment as part of PHE’s emergency preparedness and response.
PHE Notification process Upon receipt of a notification of an off-site release from a COMAH site via the local PHEC or CRCE, PHE will notify staff through an internal emergency response cascade and activate the relevant PHE response as appropriate. PHE may also alert partners (as appropriate) to the incident, in compliance with the existing Science, and Technical Advice cell (STAC) plan. A STAC is likely to be established if the incident has significant health and environmental consequences. The STAC is formed to provide advice to the Strategic Co-ordinating group (SCG) by providing scientific and technical advice when required.
Summary of Actions The local PHE Centre, supported by CRCE, will work with emergency responders and the wider NHS in responding to incidents. PHE actions may comprise: • Contacting emergency responders to ascertain details of the incident; Site Specific External Emergency Plan – V1.1 Official 23
• Undertaking public health risk assessments; • Undertaking exposure assessments; • When appropriate, convening at Science and Technical Advice Cell (STAC); • When appropriate, the Environment Agency and PHE will convene an Air Quality cell (AQC); • Providing information and public health advice direct to emergency responders and multi-agency groups (e.g. about the toxic effects of released chemicals, protective actions to be taken to protect health, health surveillance, and the need for a major incident health register); • Providing public health advice to the Fire and Rescue Service’s Incident Commander regarding the use of a “controlled burn”; • Advising emergency responders on the health considerations of response decisions (e.g. evacuation versus sheltering decisions); • Providing health messages for multi-agency media statements; • Providing information to GP’s, hospital staff and public health staff based in Local Authorities via DsPH and CCG’s; • Providing public health advice in the recovery phase of an incident.
NHS England – South West Region Consider the requirement to declare an emergency in accordance with the Local Resilience Forum Combined Agency Emergency Response Protocol – Section 5.5.1.
NHS England South (South West) provides the strategic leadership for the NHS during emergency incident involving more than one NHS provider. They are the key link between the Department of Health and the NHS in Devon, Cornwall and the Isles of Scilly.
In a major incident, NHS England will lead the NHS response to the incident within Devon, Cornwall and the Isles of Scilly. They work with Local Authorities and other agencies that provide health and social care to make sure the communities’ needs are being met. In a major incident, NHS England will co- ordinate and direct the deployment of NHS resources to meet the healthcare requirements of the incident response and the wider community.
The role of NHS England in a Major Incident is to: • Lead and co-ordinate the NHS emergency response, when more than one NHS provider is involved; • Mobilise NHS resources across organisational boundaries, as necessary, in support of the response – this includes ensuring healthcare support for evacuees and other vulnerable groups affected by the incident, including replacement medications; • Assess the health impact of an incident on the wider community; lead provider organisation’s in mitigation of that impact; • Represent the NHS at Strategic Co-ordinating Group meetings and ensure appropriate NHS representation at Tactical Co-ordinating Group meetings; • Co-ordinate communications with other emergency responder organisation’s; • Escalate to a regional or national response as necessary. • Ensure an appropriate level of NHS participation in the recovery phase. Site Specific External Emergency Plan – V1.1 Official 24
The community provider will respond either: • Consider the need to activate NHS England’s Incident Response Plan. This will facilitate the on-going co-ordination of the wider NHS response during all phases of the incident. • Provide input to a Tactical Co-ordinating Group if convened (potentially by teleconference) • Provide input at a Strategic Coordinating Group (Director from NHS England’s on call Rota). • If required, convene the Scientific and Technical Advice Cell (STAC), to be chaired by a Consultant in Communicable Disease Control (CCDC). • Supported by PHE, advise Police Commanders on the health considerations of a decision, e.g. evacuation versus sheltering (through the Scientific and Technical Advice Cell (STAC) or otherwise). • Assist PHE to assess the risk to the population. • Cascade information (including that provided by PHE) to GPs, hospital staff and Primary Care Organisation’s staff during the incident. • Liaise with all agencies including Acute Hospitals, the Ambulance Service and Primary Care Organisations. • Liaise with other agencies to ensure an appropriate response in the Recovery phase.
NHS Kernow – Clinical Commissioning Group Consider the requirement to declare an emergency in accordance with the Local Resilience Forum Combined Agency Emergency Response Protocol – Section 5.17.
Clinical Commissioning Groups will provide support to NHS England in coordinating the Health response to any emergency incident. They will do so by: • mobilising provider resources as requested by NHS England in support of the emergency response; • working with NHS providers to ensure the delivery of healthcare to the wider community through-out any emergency incident; • if asked to do so, represent NHS England and the wider NHS at Tactical Co- ordinating Group meetings.
Royal Cornwall Hospitals Trust and foundation Hospitals Trust Consider the requirement to declare an emergency in accordance with the Local Resilience Forum Combined Agency Emergency Response Protocol – Section 5.5.2.
Large Hospitals are managed by NHS Trusts; there are one Acute Trust and one Foundation Trust in Cornwall, who are responsible for the general hospitals at Treliske (Truro), and mental health services and community services in the County.
The primary areas of responsibility for Acute Hospitals Trusts during a major incident are to: • Receive and triage casualties in Accident & Emergency if designated as a receiving Hospital; • Back-up facilities in the rest of the hospital; • Support any designated receiving hospital; Site Specific External Emergency Plan – V1.1 Official 25
• Identify patients requiring transfer to specialist centres, e.g. burns and • paediatrics units as appropriate and liaison with those units; • Communicate with family and friends of existing patients and those from • the incident, the local community, the media and VIPs; • Provide specialist support at the scene of an incident, only if specifically • requested; • Counsel, advise and support, in partnership with other agencies; • Ensure that the hospital continues its entire essential functions and the • maintenance, as far as possible, of normal acute health services. • Provide decontamination for self-presenting patients. • Provide mobile team to site if requested by the ambulance service. • Implement internal major incident plan if required.
Community Health Providers Provide health care to displaced populations (including at rest centres). Ensure critical services continue to be provided to the population in the affected area.
Cornwall Council (Including Resilience & Emergency Management) Consider the requirement to declare an emergency in accordance with the Local Resilience Forum Combined Agency Emergency Response Protocol – Section 5.4
Local Authorities play a critical role in civil protection. They have a wide range of functions that are likely to be called on in support of the emergency services during the response phase, in addition to managing their own statutory duties during the Response and Recovery phases. Crucially, the Local Authority, as the main body representing the community, will lead the Recovery phase in exercising community rehabilitation and environmental protection.
Local Authorities must be notified, through the cascade system, when a major incident or emergency is declared and should be informed whenever an emergency is likely to lead to a significant impact on people or the local environment/community. The local authority will play an enabling role in close collaboration with relevant others to: • Provide shelter, warmth, refreshments and welfare support to evacuees not requiring medical attention in rest centres; • Support the Police in the operation of Survivor and Family and Friends Reception Centres, with the provision of the welfare function; • Assistance to the Police at Evacuation Assembly Points, if required; • Opening of Humanitarian Assistance Centre; • Call out voluntary sector and manage the assistance provided; • Transport for evacuees; • Provide detail of known vulnerable people within the inner/outer cordon; • Maintain, as far as possible, existing services to the community; • Provide medium to longer-term welfare of survivors and those affected, including social care support and temporary housing; • Address the communities’ on-going needs in the aftermath of an emergency; Site Specific External Emergency Plan – V1.1 Official 26
• Building Control Inspectors may be able to advise the rescue services on the condition and accessibility of damaged structures (this can involve securing or zoning the building, arranging shoring up, removal of part or all of the building in order to prevent danger and advising services such as the Fire and Rescue Authority on access). In a major emergency involving a number of buildings or structures, the role would be to coordinate these works involving a survey/assessment of each building, instigating the required works and re- inspection prior to allowing access or reoccupation; • Call out voluntary sector and manage the assistance provided; • Lead on Recovery, which is likely to carry on for a considerable time and is likely to involve many organisations that are not ordinarily involved with • emergency response; • The Director of Public Health (DPH), acting on behalf of the Local Authority, has a pivotal role in protecting the health of its population. They are responsible for the Local Authority’s contribution to health protection matters, including their role in planning for, and responding to incidents that present a threat to the public’s health; • The DPH will provide initial leadership for a range of public health incidents ranging from relatively minor outbreaks to full-scale emergencies. They will work with colleagues from Public Health England to mobilise resources in response to public health incidents and outbreaks and will liaise with NHS England Local Area Teams; • The DPH will also provide advice to Clinical Commissioning Groups and other organisation’s in their area and ensure that there is effective communication with local communities; • Cornwall Council operates a 24/7 call out Duty Rota and the Duty Officer will engage other council staff, as required. • Appoint a Duty Senior Officer to co-ordinate the Local authority’s incident response. • Ensure that Newlyn Downs Explosives Depot has activated the Site Internal & External Emergency plans. • If informed by one or more of the key responding organisation’s that a major accident has occurred or, an uncontrolled event which could reasonably be expected to lead to a major accident has occurred at Newlyn Downs Explosives Depot and, Newlyn Downs Explosives • Depot’s personnel have not activated this plan, then arrange for the Duty Resilience • St Allen County Councillor should be notified of the emergency • St Allen Parish Council should be notified of the emergency.
Environment Agency Consider the requirement to declare an emergency in accordance with the Local Resilience Forum Combined Agency Emergency Response Protocol – Section 5.6.
The Environment Agency plays an important role in preparing for and supporting the response to emergencies in England and Wales.
In an incident that has or is likely to affect the environment the EA will: • Provide specialist environmental advice Site Specific External Emergency Plan – V1.1 Official 27
• Monitor the effects of, and the response to an incident, to minimise the • impact on the environment • Work with the Health Authorities to provide them with advice on • environmental impacts, which will assist in their formulation of health • advice • Provide air quality data and advice during a major incident, if necessary • activating a National Air Quality Cell to co-ordinate air quality data and • provide fast effective public health advice to those managing the incident.
An Air Quality Cell (AQC) may be established during a major incident involving air quality, where there is the potential for significant risk to public health. The Environment Agency will contact partner organisation’s; Health Professionals, Food Standards Agency, Met Office and Health and Safety Laboratory on activation. The AQC will: • Deploy monitoring teams to sensitive receptors e.g. hospitals, schools, nursing homes to collect real-time data. This data directly informs the public health risk assessment. • Carry out air dispersion modelling to forecast the nature and scale of the plume and its potential impact on the public at large. Key messages on sheltering, evacuation and wash/peel foodstuffs will be communicated via a regular Summary Report sent directly to the TCG, or the Science and Technical Advice Cell (STAC), for the SCG • Be operational during the response phase of the incident which is normally up to 3 days • Coordinate air quality data, including monitoring and modelling during the recovery phase will be handed over to the Recovery Coordinating Group (RCG).
After an incident the EA will: • Advise on how best to dispose of any waste generated by the incident • Continue to monitor the impact on the environment • Provide information to the public on the environmental impact • Investigate the cause of an incident and take enforcement action as appropriate

SECTION 3: SITE INFORMATION In addition to other sources of information, responding organisations/agencies should refer to the following site-specific details when responding to a major accident at Redcliffe Newlyn Downs Storage Depot.
Explosives Licensing The maximum quantity of explosives permitted to be held on the site is shown in the table below. Table showing magazines storage details (maximum licensed quantities) under the current HSE licence XI/4311/987/5.
(Content removed from public consultation).
This presently consists of powder smokeless, fireworks, detonators, boosters and blasting explosives, but on occasions may contain other compatible natures. Full details of the individual hazards are given in the product MSDS supplied by the customer.
A full inventory of the stock held, including quantities and classification with CAS numbers where available, at the time of the incident, will be available to responders from Redcliffe site staff, or Head Office. CFRS has been provided with the MSDS data sheets for the commonly held substances on site.
Site holds explosives in a variety of forms. There are no other dangerous goods.
Harmful effects of the substances held on site The harmful effects of the substances held on site are as follows: In relation to a smoke plume this is assessed to contain, as a worst case scenario:
(Content removed from public consultation).
An example calculation for production of nitrogen dioxide indicates that a gas cloud would be relatively small (radius of 18 metres) and would therefore dissipate rapidly in the environment. There is considerable distance from the storage depot to the nearest residential receptors. Other trace elements from the explosive materials would be unlikely to reach high enough concentrations to cause health effects at sensitive receptors.
See technical appendix 3.

Site Specific External Emergency Plan – V1.1 Official 31
The primary function of the facility is the storage of explosives. The quantities of explosives as licenced, places the facility in the Upper Tier category as defined in the COMAH Regulations.
Site Information The site has six magazines above ground. In addition to the magazines the site includes a welfare facility; occupying a total area of approximately four hectares. There are two non-explosive storage containers: 1. A shipping container for the secure storage of the forklift and; 2. A small steel box (flammables locker) for the storage of petrol etc. for the grass cutter machine.

Location (Content removed from public consultation).
On-Site Response Arrangements The staffing levels at the facility would provide no capacity to deal with major fires and explosions. The main role of Redcliffe staff would be to provide advice and assistance to the emergency services – responsibility for this action would fall to the Site Main Controller.
Resources The Newlyn Downs Site does not have any firefighting facilities.
Site Specific External Emergency Plan – V1.1 Official 32
SECTION 4: OFF-SITE INFORMATIONhelicopter landing Supporting Off-Site Information Environment The explosives storage site is part of land which has been designated as a Site of Special Scientific Interest and a Special Area of Conservation. An environmental assessment of the site has been carried out by Environmental Resources Management Ltd (REM).
The report concentrates of the potential pollution of fire water run-off in the event of an incident. Redcliffe International is in the process of developing an Environmental Management System across all of its sites, to provide a framework to controlling and managing environmental considerations and have engaged with Belfor Red Alert as a remediation specialist in the event of an incident. Soil analysis has been undertaken to deliver a baseline assessment of the current state of the ground, both on site and in the surrounding area.
The assessment of the Major Accidents to the Environment (MATTE) risks at Newlyn Downs site was completed following guidance provided by the Chemical & Downstream Oil Industries Forum (CDOIF).
The major accident scenarios considered are detailed in Appendix 2.
The total unmitigated establishment risk for the site for a CDOIF “severe” accident has been assessed as 6.6 x 10-4 per year. This result indicates that the risk for the site is in the Tolerable if As Low As Reasonably Practicable (TifALARP). A number of mitigation measures have been applied and consists of qualitative analysis of the likelihood of fire water addition or specific exposures of certain receptors to the consequence of a fire/explosion.
Topography The site is located almost entirely within the Newlyn Downs Special Area of Conservation (SAC), which is a site of Special Scientific Interest (SSSI). The site lies at an approximate elevation of 75 metres above ordnance datum (m AOD). Each magazine is surrounded on three sides by earth mounding. The maximum elevation of the embankments is approximately 78m AOD.
The land slopes towards a small stream approximately 270m east of the site beyond which the land rises sharply towards the eastern boundary of the SAC designated area.
Hydrology The nearest surface water is the Benny Stream located approximately 270m east of the site. Indications are that the stream flows north of the site towards a larger tributary of the River Gannel which is located approximately 4.6km north of the site.
The Environment Agency River Basin Management Plan (RBMP) has classified the Benny stream as a protected area having moderate ecological status.
Site Specific External Emergency Plan – V1.1 Official 33
There are some surface drains on site which appear to be routed towards Benny stream.
Geology Indications are that the superficial deposits underlying the site comprise of poorly sorted and poorly stratified deposits of sand and gravel, silt, clay or peat and organic material. The site is a former mining site and soil analysis has been undertaken to establish ground content for remediation purposes; should an incident occur.
Hydrogeology The site is located within a Minor Aquifer Intermediate Vulnerability Zone but is not located within a Groundwater Source Protection Zone (SPZ). The nearest Groundwater SPZ is located approximately 1.2km west of the site.
Based on the topography of the area surrounding the site, groundwater is likely to flow in an easterly direction towards the Benny stream.
MATTE Assessment For credible scenarios, the pathways which could potentially result in impacts to sensitive environmental receptors were identified. These are: 1. Penetration of contamination into the ground water through addition of fire water. This could result in contamination reaching shallow groundwater with lateral migration towards sensitive receptors; 2. Emissions to air as a result of a fire or explosion with the potential to adversely affect ecological receptors; 3. Radiant heat from a fire or explosion with the potential to ignite surrounding vegetation; and 4. Overpressure generated from an explosion which may have the potential to affect the integrity of structures in proximity to the site.
Fire Transmission An initiating event which results in a fire has the potential to result in thermal transfer to combustible material, either on or off site. The radiative heat flux required to generate a fire, without direct contact with flames, is estimated to be around 10KW/m2
Given the locations of the nearest surface water and built environment features, it is considered highly unlikely that the direct effects from a fire would result in a MATTE at these receptors.
Combustion A fire has the capacity to transfer materials from the burning process into the air with subsequent potential for deposition at/on sensitive receptors. In the burning of explosives the major components are NOx, CO (rapidly evolving to form CO2).
The pollutants associated with an explosion or fire are short-term events. The impacts at sensitive ecological receptors are primarily focussed on longer term changes in vegetation. Where the feature of interest is fauna, then these are largely reliant upon the maintenance of the health of the underlying floral habitat and general ecosystem. Site Specific External Emergency Plan – V1.1 Official 34
Newlyn Downs site is primarily semi-natural flora (based on the citation for SSSI), which is considered to be the most sensitive receptor.
The Air Pollution Information System (APIS) website sets out evidence relating to the potential impact of atmospheric pollutants on protected habitats, both flora and fauna, and this has been used as the primary source of information to define those pollutants that are of interest, and assess potential impacts from atmospheric deposition.
On the basis of the evidence set out in APIS, emissions of oxides of nitrogen and associated deposition of nutrient nitrogen and acid nitrogen are the only significant pollutants from a fire or explosion at the site.
On this basis, a one-odd dose of nutrient associated with a short term nitrogen deposition is considered to be of negligible significance as there is considered to be no significant potential for long term changes in flora composition at the identified sensitive receptors.
Similarly, impacts associated with acidification effects are long term. On this basis, a one-off dose of acid associated with a short term nitrogen deposition is considered to be of negligible significance.
Overall, emissions to air as a result of fire or explosion at the site are considered to have negligible effects on sensitive ecological receptors and, would be unlikely to contribute to a MATTE event.
Based on a review of the initiating events, the following environmental receptors are considered to be at risk of a MATTE; • The Newlyn Downs SAC/SSSI as a result of combustion of flora as a result of direct contact with a fire or from spreading of thermal radiation following a fire or explosion; • Built environment – primarily the closest listed building, which may be at risk of damage due to overpressure generated from an explosion. • Groundwater (non-drinking water source) as a result of infiltration of firewater into the sub-surface, which could mobilise contaminants from the explosives and impact the underlying Secondary A aquifer. • Surface water of the Benny stream which is located down topographic gradient of the site and which may be connected to the site by the drainage system. The principle pathway is likely to be via overland flow or channel flow via these drains rather than as a result of baseflow of contaminated groundwater.
Overall, the Redcliffe Newlyn Downs site lies in the “Broadly Acceptable” CDOIF risk zone for potential impacts to the built environment, groundwater and surface water receptors. Site Specific External Emergency Plan – V1.1 Official 35

Appendix 3 – Technical data
Previous analysis undertaken by the manufacturers of the various explosive and pyrotechnic compositions used in the currently stored materials, show that the primary gaseous constituents given off during burning of the energetic materials, are carbon monoxide, hydrogen sulphide, sulphur dioxide, carbon oxides, organic compounds, aromatics compounds and nitrogen oxides. The major constituent element of the solid particulates is carbon, with trace levels of copper, lead, chromium and sulphur also being present. The heavier particles would be deposited closer to the fire, probably within 200m, with the smoke and lighter particles being dispersed by the wind. Other airborne constituents from the base fire, such as smoke, carbon dioxide and water vapour will also be present in large quantities, but are dependent on the materials found in the base fire, e.g. pallets and packaging, building materials, vegetation. It is estimated that any fall-out contamination will be retained within 5cm of the surface soil where deposited. Each of the major hazard scenarios identified are described in these terms.
Scenario Pressure Fragment Thermal Oxygen Toxic effects effects effects depletion effects
Hazard Probably Possibly Possibly Probably Possibly Type 1 storage
Hazard No Probably Possibly Probably Possibly Type 2 storage
Hazard No No Probably Probably Possibly Type 3 storage
Hazard No No Probably Probably Possibly Type 4 storage
Storage of Worst case Hazard Type applies mixed explosives
Processing None permitted of explosives
The site does not currently store ammonium nitrate as a single substance but does have substantial stocks of materials containing nitrocellulose. However, ammonium nitrate is present as a constituent of some of the materials held.
