GLOSSARY

Bund: Secondary containment for an aboveground storage tank consisting of a base and surrounding walls constructed or lined with a material impermeable to stored Petroleum, Oils or Lubricants (POL).

Facility Response Team: The primary organisation responsible for overall spill prevention, control and countermeasures at RAF Menwith Hill. This team is headed by the RAF Menwith Hill Fire Chief and includes the key members, Defence Estates and the Chief, Environmental Flight.

Environment Agency: The leading public body for protecting and improving the environment in England and Wales.

Geographical Information System (GIS): A GIS is a system of hardware, software, and data that facilitates the development, enhancement, modelling, and display of multivariate (e.g. multilayered) spatially referenced data. It performs some analytical functions itself, and by its analysis, selective retrieval and display capabilities, helps the user to further analyze and interpret the data. Properly configured, the GIS can model (e.g. synthetically recreate) a feature or phenomenon as a function of other features or phenomena which may be related -where all features or phenomena are represented (characterized) by spatial and related tabular data.

Hazardous Material: Any material that is capable of posing an unreasonable risk to health, safety, or environment if improperly handled, stored, issued, transported, labelled, or disposed because it displays a characteristic as listed in Table 5-1 of the FGS-UK or the material is listed in Appendix A, Table A.3 of the FGS-UK.

Hazardous Waste (Special Waste): A discarded material that may be solid, semi-solid, liquid, or contained gas and either exhibits a characteristic of a hazardous waste as listed in Appendix A, Section A-1 of the FGS-UK, or listed as a hazardous waste in Table A.3 Chapter 6 of the FGS-UK.

Hazardous Waste Accumulation Point (HWAP): A shop, site, or other work centre where hazardous waste is accumulated until removed to a HWSA or shipped for treatment or disposal. A HWAP may be used to accumulate an aggregate of no more than 55 gallons of hazardous waste, or 1 litre (or quart) of acute hazardous waste.

Hazardous Waste Profile Sheet: A document which identifies and characterizes the waste by providing generating activity’s knowledge of the waste, and/or laboratory analysis, and details the physical, chemical and other descriptive properties or processes which created the hazardous waste.

Hazardous Waste Storage Area (HWSA): One or more locations on an installation where hazardous wastes are collected prior to shipment for treatment or disposal. The HWSA may store more than 55 gallons of a hazardous waste. The HWSA may consist of a lockable unit (cabinet, room) or a combination of lockable units that are next to each other as long as the lockable unit or combination of lockable units is located within a restricted access area.

Hazardous wastes may be stored in a HWSA for no longer than one year.

viii

Generating Activity: The organization responsible for generating the hazardous waste.

Initial Responder: The unit/activity or person who discovers the spill. The generating activity may also be the initial responder upon discovery of the spill.

Spill Levels: Categories of spill dependent on the substance and the quantity. The spill response procedures are dependent on the spill level.

- Spill Level 1: POL< 1 Gallon (3.8 litres) or HAZMAT < 1 Gallon (3.8 litres).

- Spill Level 2: POL > 1 Gallon (3.8 litres) but < 5 Gallon (19 litres) or HAZMAT < 1

Gallon (3.8 litres).

- Spill Level 3: POL >/= 5 Gallon (19 litres) or HAZMAT >/= 1 Gallon (3.8 litres).

- Spill Level 4: POL >/= 5 Gallon (19 litres) or HAZMAT >/= 1 Gallon (3.8 litres).

SECTION 1

INTRODUCTION

1.1 OVERVIEW AND PURPOSE

It is the policy of the United States (U.S.) Department of Defense (DoD) to prevent spills of hazardous materials (HM) and hazardous wastes (HW) that result from DoD activities, and to provide for a prompt, coordinated response to contain and clean up any spills (FGS-UK 18-2).

This Spill Prevention, Control and Countermeasures (SPCC) Plan for Royal Air Force (RAF) Menwith Hill describes procedures to prevent, control and, if necessary, clean up spills of all hazardous substances, which include both HM and HW. Within this plan hazardous substances will be described as HAZMAT, which includes both HM and HW.

UK Ministry of Defence (MoD) environmental policy, as described in the Joint Services Publication (JSP) 418, is the host nation driver for this SPCC plan. These environmental requirements are incorporated into the FGS-UK (2002). It should be noted that it is Defence Estates role to advise on MoD requirements in relation to contaminated land and general MoD estate issues. Defence Estates also has responsibility in relation to United States Visiting Forces compliance with environmental requirements.

The procedures contained in this SPCC Plan are based on numerous U.S. DoD, and U.S. Air Force laws, regulations, policies, and other guidance. The key regulatory requirements are noted below, in descending order of their relative hierarchy of application for spill prevention and response.

- FGS-UK (2002), Chapter 5, 6, 18 and 19;

- MoD Joint Services Publication (JSP) 418, Environment Manual (1999);

- Air Force Instruction 32-4002, Hazardous Material Emergency Planning and Response

Program (1997); and

- Air Force Manual 32-4013, Hazardous Material Emergency Planning and Response

Guide (1997).

The laws and regulations governing the management of HAZMAT are continually changing and evolving. Therefore, the procedures contained in this SPCC Plan must be revised periodically to remain current.

1.2 INSTRUCTION ON PLAN USE

The main objective of this plan is to prevent spills and to limit the potential impact that spills may have on the Base and the surrounding environment through prevention, control and countermeasures procedures.

In order to achieve this objective, this SPCC Plan incorporates site-specific details for RAF Menwith Hill and its associated operations, and provides procedures to prevent, control and countermeasure spills at the Base. Specific information included in this Plan is as follows:

• Base Overview including general information on the military mission of RAF Menwith Hill and the environmental setting (Section 1);

1-2

• Spill Response Action Plan including a diagrammatic emergency response and reporting procedure (Figure 2.1, Section 2);

• Responsibilities and points of contact (POC) for spill prevention and response, including details on the Facility Response Team (Section 2);

• Hazard Identification – identifying spill hazards (location of HAZMATs), areas of vulnerability and associated risks (Section 3);

• A Spill Response Geographical Information System (GIS) accompanies the Spill Response Action Plan, this system identifies the main HAZMAT locations (including tanks, hazardous material and hazardous waste storage areas), drainage patterns including the location of interceptors and the final outfalls. This system highlights the areas which are vulnerable to spills and allows for the identification of probable spill pathways;

• Spill Prevention procedures, roles and responsibilities (Section 4);

• Current capabilities of RAF Menwith Hill to control a spill and recommendations for improvements (Section 5);

• Spill Response Functions – roles and responsibilities (Section 6);

• Spill control, containment and cleanup information (Section 7);

• Procedures for documentation and investigation of spills (Section 8);

• Procedures for testing the plan and training requirements (Section 9);

• Record-keeping and updating requirements (Section 10);

• Department and unit/activity specific spill response action flowcharts (Appendix A);

and

• An inventory of tanks and oil interceptors (Appendix D & E).

1.3 PLAN DISTRIBUTION

A copy of this SPCC Plan must be maintained at each facility or unit at RAF Menwith Hill where HM or HW is used, generated, transported, stored, handled, or disposed. For example, a copy of the SPCC Plan, and any revisions, must be maintained at the new HW and HM storage area outside Gate D (located near Building 48). Each person/department responsible for spill prevention and response should also maintain a copy of the plan including:

• RAF Menwith Hill Fire Chief and Fire Department;

• Defence Estates;

• Chief, Environmental Flight;

• Chief, Health and Safety (HS) Department;

• Unit and building supervisors, for example the supervisor of the motorpool, and

HAZMAT storage areas;

• RAF Menwith Hill Commander; and

• U.S. Menwith Hill Station Commander.

A GIS Spill Response (see Section 3) has been developed in coordination with this SPCC Plan. This is an important part of the spill response and control procedures, it will enable the location of spills to be identified and the most likely spill pathway to be determined. It can be used as an early warning system so that receiving interceptors can be closed thereby containing the spill. Defence Estates will also be able to determine the risk of the spill migrating off-base. The original GIS Spill Response, which accompanies this Plan, should be located on the local network of the Drawing Office at RAF Menwith Hill. The Fire Department, Defence Estates and the Environmental Flight should have access to view this system.

1-3

1.4 RECORD OF AMENDMENTS

This SPCC Plan is a dynamic document that must be reviewed and updated regularly to maintain its accuracy and to ensure compliance with applicable requirements. The Chief, Environmental Flight is responsible for the overall content and effectiveness of this plan and will be responsible for updating this Plan in coordination with the Fire Department and Defence Estates. The Environmental Flight will also be responsible for ensuring that the GIS Spill Response is updated to reflect the current status of the Base. The date box on the GIS Spill Response should coordinate with the date on the hard copy of the SPCC Plan.

The signature sheet at the beginning of this plan should reflect the current status of this plan and detail the most recent date of this plan, along with the signature of the Chief, Environmental Flight.

1.5 BASE OVERVIEW

1.5.1 Mission Statement

RAF Menwith Hill is a Communications Research and Rapid Relay Facility, which was originally established in the 1950’s.

1.5.2 Environmental Setting

RAF Menwith Hill is located in rural North Yorkshire approximately 8 miles (13 kilometres (km)) west of the city of Harrogate, 20 miles (32 km) north of Bradford, and 222 miles (357

km) north of London.

1.5.3 Geology, Hydrogeology and Hydrology

Geology

RAF Menwith Hill lies at approximately 210 to 230 metres above sea level. The underlying geology is Carboniferous Millstone Grit which is overlain by a thin cover of glacial boulder clay. The glacial cover across the site varies from 1.5 to 3 metres thick.

The Millstone Grit originated as deltaic sediments about 310 to 320 million years ago. The deltas formed sheets of sand (Namurian sandstone) which subsided periodically and were covered with thick beds of silt and mudstone. The resulting underlying geology consists of Namurian sandstone with layers of silt and mudstone.

Hydrogeology

The sandstone layers of the underlying Millstone Grit allow for the formation of aquifers within this area. The groundwater potential is variable and depends upon the thickness, lithology, the extent of fissuring of the sandstone unit and also the local topography.

There are no groundwater boreholes within the boundary of RAF Menwith Hill, however there are a few small groundwater abstraction boreholes in the surrounding area, the water from which is used for domestic or agricultural purposes. The level of the permanent water table is unknown.

1-4

Hydrology

There are a number of small streams to the north and east of the base which drain to the River Nidd in the north. It is likely that these streams are sourced from the underlying aquifers within the sandstone layers. The nearest natural surface water feature to the Base is a small stream (Little Slack), which flows from the southwestern corner of the Base into the Swinsty Reservoir which is 1.2 miles (2 km) southwest of the site perimeter.

A small lake/wetland Lake Spiri which was excavated in the mid 1970’s is situated just to the south of the Base. Runoff from the base flows via an interceptor (no. 19) to this lake, the outlet from this lake eventually discharges into the Swinsty Reservoir.

1.5.4 Drainage

Storm water drainage within the developed portion of the Base flows via a piped drainage system, which connects to a number of interceptors, before discharging at several points off-base to local ditches. There are a total of twenty interceptors, details of which are provided in Appendix E.

Storm water outfalls are checked weekly and after periods of heavy rainfall. Defence Estates holds a discharge permit for storm water discharges from the Base as issued by the Environment Agency (EA). This permit stipulates the quality parameters of the discharge, which include: no more than 30mg/l of suspended solids and no visible traces of oil/grease.

The storm water is monitored quarterly and the results are maintained by Defence Estates.

Figure 1.1 illustrates the drainage system of the Base and highlights the location of the interceptors and the respective outfall. Existing baseline information on the drainage system and the location of manholes, interceptors and outfalls was utilised to develop the GIS Spill Response. Potential spill pathways, based on the concept of the spill flowing to the nearest manhole, have been identified in the GIS Spill Response. Due to incomplete/inaccurate data on the drainage system some of the drainage data had to be manipulated, as identified in the GIS Spill Response.

1.6 CONCEPT OF OPERATIONS AND RESPONSIBILITIES FOR

RESPONSE

1.6.1 Governing Principles

All operations within the Base are mission support operations. The Operations Compound comprises of secure buildings with associated operating and maintenance facilities. Large quantities of HAZMATs primarily in the form of fuel are stored in this area. The Base Operations Support Site has supporting services including administrative facilities, petrol station, motor pool, vehicle washrack and various workshops. HAZMATs are generally stored in smaller quantities in this area with the exception of the fuel tanks.

This SPCC Plan is applicable to any base activities involving HAZMAT, therefore this plan applies to all facilities, units, activities, and organizations within RAF Menwith Hill that use, generate, transport, store, handle, or dispose of HAZMATs.

1-5

1.6.2 Organization, roles and responsibilities

All individuals at RAF Menwith Hill will be responsible for localized spill prevention under the guidance of the unit/building supervisor. However, there will be one organization, a Facility Response Team, headed by RAF Menwith Hill Fire Department, which has overall responsibility for the spill response.

The Facility Response Team will be established at RAF Menwith Hill and will consist of the following key members: the RAF Menwith Hill Fire Chief (and Fire Department), Defence Estates, Chief, Environmental Flight and the Chief, HS Department. Additional members who are primarily involved in spill response procedures include the RAF Menwith Hill Commander and the local host nation fire service North Yorkshire Fire and Rescue Service at Selby.

The main responsibilities of the Facility Response Team will include:

• Implementation of the Spill Prevention Procedures;

• Response to a spill incident;

• Spill clean-up and countermeasures;

• Training of spill prevention and control/cleanup of minor spills;

• Biannual meetings;

• Participation in annual drill; and

• Review and updating the SPCC plan.

Further details on the individual roles and responsibilities of the members of the Facility Response Team are available in Section 2.

1.6.3 Relationship to other plans

A Hazardous Waste Management Plan (RAF Menwith Hill Environmental Health and Safety Procedure 103 (EHSP-103) Revision A) has been completed for RAF Menwith Hill.

Information from that plan is incorporated into this SPCC Plan. The Hazardous Waste Management Plan should be used in conjunction with this SPCC, to optimize the effectiveness of spill prevention and control procedures.

SECTION 2

SPILL RESPONSE ACTION PLAN

This section of the SPCC Plan describes the specific actions, which are to be taken following a spill within RAF Menwith Hill (Section 2.1). The actions to be taken by the initial responder and the Facility Response Team are described in Section 2.2.

2.1 SPILL RESPONSE PROCEDURES

This section describes the immediate and prioritized response actions to be taken when a spill is discovered. The response procedure for spills is dependent on the spill material and the quantity of the spill.

At RAF Menwith Hill, spills are categorized into four spill level categories. Spill Levels 1 and 2 represent minor spills, which can be contained by the generating unit/activity while Spill Levels 3 & 4 are major spills, which require emergency action. The spill levels are defined below along with the required action. Figure 2.1 summarizes the spill response procedure.

• Level 1 Spill – Negligible. If Petroleum, Oils or Lubricants (POL) or HAZMAT < 1 gallon (3.8 litres).

1. Unit/activity will contain/clean up a Level 1 spill.

2. Unit/activity will report the spill to the unit supervisor only.

3. Unit/activity will coordinate the disposal of absorbent, soil and other cleanup material with the Environmental Flight.

• Level 2 Spills – Small. If POL > 1 gallon (3.8 litres) but < 5 gallon (19 litres) or if

HAZMAT < 1 gallon (3.8 litres).

1. Unit/activity will contain/clean up a Level 2 spill.

2. Unit/activity will report the spill to the unit supervisor.

3. Unit/activity will report the spill by phone, fax, or e-mail within 24 hours to Defence

Estates.

4. Defence Estates will notify the U.S. Menwith Hill Station Commander, RAF Menwith

Hill Commander and Chief, Environmental Flight.

5. Unit/activity will coordinate the disposal of absorbent, soil and other cleanup material with the Environmental Flight.

• Level 3 Spills – Medium. If POL >/= 5 gallon (19 litres) or if HAZMAT >/=1 gallon

(3.8 litres) and exceeds unit’s capability to contain/cleanup.

1. Unit/activity will determine that the spill is a Level 3 spill.

2. Unit/activity will immediately contact RAF Menwith Hill Ministry of Defence Police

(MDP) at (999/911 or 777999 (housing phone) or 01423 777 999 (mobile number) who in turn will contact RAF Menwith Hill Fire Department and Defence Estates.

3. The Fire Department will respond and contain the spill.

4. RAF Menwith Hill Fire Chief will obtain additional materials, personnel, and equipment from Civil Engineering to contain spill if needed.

5. Defence Estates will immediately notify U.S. Menwith Hill Station Commander, RAF

Menwith Hill Commander and the Chief, Environmental Flight.

2-2

6. Once containment has been completed, Defence Estates will coordinate/handle final cleanup and disposal actions with the Environmental Flight.

• Level 4 Spills – Large. If POL >/= 5 gallon (19 litres) or if HAZMAT >/=1 gallon (3.8 litres) and exceeds RAF Menwith Hill capabilities to contain and cleanup; outside assistance is required.

1. Unit/activity will determine that the spill is a Level 4 spill.

2. Unit/activity will immediately contact MDP at (999/911 or 777999) who in turn contact the RAF Menwith Hill Fire Department and Defence Estates.

3. The Fire Department will respond and contain the spill.

4. RAF Menwith Hill Fire Chief will obtain additional materials, personnel, and equipment from Civil Engineering to contain the spill if needed.

5. Defence Estates will immediately notify U.S. Menwith Hill Station Commander, RAF

Menwith Hill Commander and Chief, Environmental Flight.

6. If the Fire Chief determines that the spill incident has exceeded the capabilities of RAF

Menwith Hill assets, he will request assistance from host nation emergency response (fire, ambulance, police).

7. Defence Estates will communicate with host nation regulators such as the Environment Agency, English Nature and the Local Authorities and negotiate cleanup requirements with the host nation authorities. Defence Estates will advise the Environmental Flight of requirements, and upon agreement with the Environmental Flight, Defence Estates will contract the cleanup and disposal actions with UK contractors.

SECTION 3

HAZARD ANALYSIS

3.1 INTRODUCTION

It is important that potential spill hazards are identified, and the most vulnerable areas highlighted, to minimize potential impacts on sensitive groundwater and surface water receptors in the surrounding area.

The information within this section should be utilized to improve spill prevention measures, and to aid spill response control by identifying potential spill pathways (through the GIS Spill Response) and highlighting areas where spills impacts would be most severe.

Figure 3.1 highlights the areas where there is a greater potential for spills by identifying the location of HAZMAT storage areas, large car parks and tanks. This map also highlights the Vulnerability Zones as defined in Section 3.3.

The GIS Spill Response is a vital part of the Spill Response procedure. Access to view the GIS Spill Response will be controlled by the Chief, Environmental Flight, who will also be responsible for ensuring that the system is updated when necessary. In responding to a spill, Defence Estates should consult this system to identify the potential pathway of a spill, the receiving interceptor and the final outfall. Utilizing this system will enable the spill to be contained by closing the receiving interceptor, and thereby reducing the risk of impact of pollution.

3.2 HAZARD IDENTIFICATION

Spill hazards are primarily considered to be HAZMATs (hazardous materials and hazardous wastes) which are either located at specific locations or throughout the installation.

3.2.1 Hazardous Wastes

Once a waste is designated as a hazardous waste (see RAF Menwith Hill Hazardous Waste Management Plan, (EHSP-103, Revision A), the generating activity is responsible for informing the Environmental Flight and submitting a Hazardous Waste Profile Sheet (HWPS). The Environmental Flight arranges for the wastes to be collected and transported to on-site Hazardous Waste Accumulation Points (HWAP) or Hazardous Waste Storage Areas (HWSAs). The majority of hazardous waste at RAF Menwith Hill is located at a HWAP or the HWSA, with the exception of newly generated hazardous wastes. Table 3.1 lists the HWAPs and HWSA and their location.

The location of HWAP and HWSA are illustrated in Figure 3.1.

3.2.2 Hazardous Materials

Hazardous materials include: petrol, diesel, paints, acids, solvents and water treatment chemicals. The majority of hazardous materials stored on base are in the form of oil and fuel, which are either stored in underground storage tanks (UST) or aboveground storage tanks (AST). Table 3.2 provides details of all of the AST/UST at RAF Menwith Hill.

Other hazardous materials include substances such as: paints, degreasers, cleaning products, which are stored indoors at most facilities/buildings in smaller quantities usually in sealed containers. This plan only identifies the locations of larger quantities of these substances.

Table 3.3 lists the locations/buildings were such materials are stored.

Leaks from vehicles are another potential source of spills from hazardous materials. In particular, car parks with over fifty parking spaces pose a risk of pollution to surface water drains. The potential quantity of hazardous material arising from a leak/spill is likely to be minimal (< 1 gallon (3.8 litre)), however it is possible that oil residues could migrate during heavy rainfall to surface water drains. The location of large car parks is also included in Table 3.3.

3.3 VULNERABILITY ANALYSIS

This section identifies areas, which are vulnerable to spills, and also assesses the level of vulnerability. For the sole purpose of this SPCC Plan the installation is divided into areas of varying vulnerability, which are categorized as Vulnerability Zones I, II and III. The primary influencing factor in establishing whether an area is vulnerable to spills is the presence or absence of HAZMAT storage areas. Other factors, which can affect the level of vulnerability, include:

- Storage of HAZMATs.

- Location – internal/external.

- Proximity to drains.

- Spill pathway (whether it may migrate to an interceptor).

- Capacity of interceptors.

- Vulnerability of catchment area.

Figure 3.2 illustrates the main factors upon which the Vulnerability Zones at RAF Menwith Hill were devised. The Vulnerability Zones are as follows:

• Vulnerability Zone I: Areas which are not vulnerable to spills, e.g. housing areas.

• Vulnerability Zone II: Areas where there are spill hazards i.e. where HAZMATs are located. However the impact of a spill would be minimum, as the spill flow would most likely flow via an interceptor.

• Vulnerability Zone III: Areas where there are major spill hazards i.e. fuel tanks and where the receiving drain has no interceptor.

The majority of the installation has been zoned as Vulnerability Zone II. Hazardous materials and hazardous wastes are stored throughout the base, however the majority of storm water drains within the installation have interceptors, therefore any spills should be contained within the base. Figure 3.1 highlights Vulnerability Zone II, the remaining area is considered Vulnerability Zone I.

3.4 RISK ASSESSMENT

This section assesses the risk of damage both on-base and off-base due to a HAZMAT release at RAF Menwith Hill. Spills could impact sensitive off-site receptors through the following routes:

- Surface runoff with potential contaminants discharging to the drains and entering the Little Slack stream (which flows from the southwest corner of the Base) and subsequently flowing into the Swinsty Reservoir which is used for public supply.

- Vertical seepages impacting the underlying Namurian aquifer. If this impact is sufficient it may impact adjacent surface springs or local abstractions.

Spill prevention procedures can reduce the risk of spills by establishing work practices that are less likely to result in the uncontrolled release of HAZMAT. Therefore it is important that spills are prevented, and where spills occur they are contained and cleanup to a standard as specified by the Environmental Flight.

RAF Menwith Hill has a proactive approach to spill management. Spill prevention and control measures are in place to reduce the potential of a spill. Spill prevention measures are detailed in Section 4 of this SPCC plan and in the RAF Menwith Hill Hazardous Waste Management Plan (EHSP-103, Revision A).

In the unlikely event of a spill, the risk of impact is reduced through spill control measures which are in operation at the Base. As identified in Section 3.3, the majority of RAF Menwith Hill is categorized as Vulnerability Zone II. There are significant spill hazards within these zones, however the receiving surface water drains are connected to interceptors, and therefore in the event of a spill, the spill could be contained at the interceptor and prevented from migrating off base. These interceptors along with the condition of the tanks, and the outfalls are regularly inspected and maintained to ensure effective containment of a spill.

Though there are areas within the installation which are vulnerable to spills, the actual risk of impact to the environment on-base and off-base is minimal.

SECTION 4

SPILL PREVENTION

4.1 INTRODUCTION

This section of the SPCC Plan provides procedures that are to be followed to prevent spills of HAZMAT within RAF Menwith Hill. The prevention of spills is the most important concept of this plan. Spill prevention requires a proactive approach by the various units/departments at the installation. By adhering to spill prevention procedures, the potential for spills is minimized.

There are various causes of spills, the most common being human error and structural failure.

The risk of spills can be reduced by establishing spill prevention procedures (work practices and spill containment structures) which will be implemented at RAF Menwith Hill. Many of the spill prevention procedures within this section are already being implemented at the installation. To date there has been very few spill incidents and no major spills. The installation will continue with current prevention methods and implement additional preventive measures as identified below.

The spill prevention programme described in this section consists of the following elements:

• General operating procedures for spill prevention;

• Spill prevention structures and equipment;

• Inspection and surveillance;

• Security measures; and

• Training and awareness.

4.2 GENERAL OPERATING PROCEDURES FOR SPILL PREVENTION

Storage, handling and transport of all HAZMAT will be conducted in accordance with the requirements of Chapters 5, 6, 9 and 19 of the FGS-UK. The Hazardous Waste Management Plan (EHSP-103, Revision A) also provides specific standards for environmental protection and spill prevention at RAF Menwith Hill. The Hazardous Waste Management Plan limits the potential for spills by providing technical guidance for effective management of hazardous wastes. General operating procedures for storage, handling, and transportation of HAZMAT to prevent spills are as follows:

4.2.1 Storage

• Secure area.

• Segregate chemicals as required.

• Label all HAZMATs.

• Provide Material Safety Data Sheets (MSDS) for all HMs. The MSDS provide information on how to transport, handle, store and dispose of individual HM.

• Seal and leak-proof floors of HAZMAT Storage Areas.

• Provide secondary containment based on the quantity/type of HAZMAT (e.g. 200L of oil).

• Provide additional storage requirements for toxic and flammable materials.

4-2

4.2.2 Handling

• Follow DoD Handling Requirements in Storage and Handling of Hazardous Materials, DLAI 4145.1 at all times.

• Maintain indoor and outdoor HM dispensing areas properly.

• Provide drip pans or absorbent materials at dispensing containers/fill points to collect drips or spills.

• Mark all dispensing container contents clearly.

• Locate dispensing areas away from catch basins and storm drains.

• Observe load capacity of tanks.

• Provide personnel training on handling of HAZMATs.

4.2.3 Transportation

• Transport HAZMAT in sealed containers.

• Use appropriate material handling equipment and vehicles.

4.3 SPILL PREVENTION STRUCTURES AND EQUIPMENT

The following spill prevention structures and equipment will be used for spill prevention:

• Secondary containment such as bunding.

- All Petroleum, Oils and Lubricants (POL) bulk storage aboveground storage tanks

(AST) must have secondary containment (bund) which is sufficient to hold 110% of the contents of the largest single tank. The bund base and wall must be impermeable to water and oil. There should be no direct outlet connecting the bund to any drain, sewer, watercourse or unmade ground.

• Double-walled tanks.

- All new underground storage tanks (USTs) will be double-walled. All old USTs were to be replaced by 1st October 2004.

• Leak detection systems on USTs and interceptors.

- All USTs must have leak detection systems, capable of detecting 0.1 gallon (0.38 litre) per hour. New USTs will use one of the following leak detection systems:

- Automatic tank gauging;

- Vapor monitoring;

- Groundwater monitoring; or

- Interstitial monitoring.

• Overfill protection on USTs.

- New USTs must be provided with spill and overfill prevention equipment, except where transfers are made in amounts of 25 gallons (95 liters) or less. Where spill and overfill protection are required, a spill containment box must be installed around the fillpipe. Overfill prevention must be provided by one of the following methods:

- Automatic shut-off device (set at 95% of tank capacity).

- High level alarm (set at 90% of tank capacity).

• Drip pans will be placed under any filling points which are not located within a bunded area.

• Maintain/repair tanks, secondary containment structures, interceptors.

4-3

4.4 INSPECTION AND SURVEILLANCE

• Conduct weekly inspections of tanks, interceptors, secondary containments and outfalls.

Additional inspections should be conducted following heavy rainfall.

- Tanks will be visually inspected where possible. The immediate area around a tank and filling point will be checked for staining or possible odours.

- Secondary containment will be checked for accumulated rainwater to prevent loss of spill containment capacity.

- Interceptors will be inspected for oil and sludge, and cleaned accordingly.

- Outfalls will be checked to ensure drainage system remains free from blockages.

• Conduct tank integrity testing at least every 5 years.

• Test leak detection systems/alarms monthly.

• Inspect HAZMAT storage areas monthly to ensure spill prevention measures as detailed in

3.2 are being implemented.

• Car parks (as identified in Table 3.3) will be visually checked monthly for staining.

• Records of inspections will be maintained.

4.5 SECURITY MEASURES

• Secure area.

- HAZMAT storage areas must be secured (e.g.
