4 POTENTIAL SPILLS AND BATCH DISCHARGES (SLUGS)

4.1 Introduction

A plan for spills and batch discharges is required by C4.3.2.1.6 of the FGS. Activities or installations that have a significant potential for spills or batch discharges (into the wastewater system) will develop a slug prevention plan. Each plan must contain the following minimum requirements:

• Description of discharge practices, including non-routine batch discharges.

• Description of stored chemicals.

• Plan for immediately notifying the domestic wastewater treatment system (DWTS) of slug discharges and discharges that violate prohibitions under this section, including procedures for subsequent written notification within five days.

• Necessary practices to prevent accidental spills. This would include proper inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, and worker training.

• Proper procedures for building containment structures or equipment.

• Necessary measures to control toxic organic pollutants and solvents.

• Proper procedures and equipment for emergency response, and any subsequent plans necessary to limit damage suffered by the treatment plant or the environment.

4.2 Facility Layout of the Sanitary Wastewater System (SWWS)

Thule AB is situated in an area with a very low population density, approximately 65 miles from the nearest village. The climate is described as arctic desert.

Due to very low temperatures, the sanitary wastewater system (SWWS) on base consists of insulated black steel pipes located above ground with heat tracing. The wastewater runs gravitationally through the steel pipes to Bldg. 984, where it is discharged through an underwater pipeline into the North Star Bay.

At 12 SWS, wastewater is directed to a septic tank, from where it is dispersed over a mountainside.

Wastewater from Bldg. 107, 555, 605, 1201, 1307, 1951, 1971 and 1824 (Det 1) is collected in a tank. A special truck collects the contents. The contents are discharged into the SWWS at Bldg. 984.

The majority of water directed to the SWWS originates from household sources like showers, washrooms, laundry rooms and kitchens. The only direct drainage from floors outside the dormitories are in Bldg. 107, 118, 236 and 4016. In all other situations, the water is pumped or manually poured into the SWWS.

No storm water leads to the SWWS.

Consult Appendix 2 for a diagram of the SWWS on the main base.

Thule Air Base, Greenland 9/23 FY-15

4.3 Discharge Practices

The main discharges made to the SWWS are what can be expected for at place where 700 people are living and with some craftsman-like activities but without any industrial activities.

4.3.1 Discharges of sanitary wastewater collected by truck

Some of the wastewater is transported by truck, as mentioned in section 4.2.

4.3.2 Water from boilers and heating system

On main base, the primary source of heating is a high-pressure steam system. Heat is produced at three different locations: Bldg. 1391, 241, and 341. Due to high levels of impurities in the boiler water, it is necessary to replace the water and discharge to the SWWS.

To prevent corrosion, a number of additives are used and subsequently discharged into the

SWWS.

Further heating is produced on low-pressure systems at Bldg. 1401, 1824 and 4016. From those places, only small amounts of boiler water are expected to be discharged to the SWWS – primarily in case of maintenance of the systems.

Blowdown water from boilers does not contain any regulated pollutants and is discharged to host nation water bodies.

4.3.3 Water from washing of aircraft/vehicles

Aircraft are not washed at Thule AB, except for the small helicopter operated by Air Greenland.

The helicopter is washed in HG-4 (Bldg. 606), where the water is directed through an oil/water separator to the sewage system.

Vehicles are washed at the following facilities: Bldg. 580, 622, and 1408 . In all facilities, the wash water is directed to an oil/water separator. From there the water is discharged through the sewage system directly to the North Star Bay.

The outdoor wash ramp near the harbor (no facility number assigned) was abandoned and dismantled during summer 2014.

During summer 2011 a new wash ramp has been established in Bldg. 605 (Hangar 3). The wash ramp is intended for washing larger vehicles from the Pavement and Ground Department. These vehicles were washed previously in bldg. 836. Bldg 836 is now scheduled for demolition in accordance with the consolidation plan for Thule AB and the wash ramp has been abandoned.

4.3.4 Water from the laundry shop

In the laundry shop, Bldg. 237, clothes are rinsed or washed. The rinsing process is designated as a dry-cleaning process. Methylene chloride was previously used, but has been substituted with Hydroclene Fluid. Residuals from the rinsing process are required to be treated as hazardous waste and collected for disposal to ensure nothing is introduced to the SWWS.

Conventional detergents are used for the washing process. Water from the washing process is led to the SWWS directly from the machines. In case of spillage, the water will be recovered in a drain, from which the water will be pumped to the SWWS.

Thule Air Base, Greenland 10/23 FY-15

4.3.5 Water from parts washers

There is only one existing parts washer at Thule AB. It is located in Bldg 580 (Vehicle Maintenance).

The water from the parts washer in Bldg. 580 is directed to an oil/water separator and from there to the SWWS. Any remaining slug is transferred to storage drums.

4.3.6 Discharge of water from swimming pool

During the summer 2006, an endless pool was installed at the Sport and Fitness Center in Bldg.

608. The endless pool is emptied out and cleaned every second month. The volume of water introduced to the SWWS is estimated to be 12 m3. The concentration of sodiumhypochlorite is

1.5 ppm. There are no emergency response related to slug management.

Beside the normal use of chlorine, the water is sanitized using a treatment filter that releases small quantities of copper and silver.

4.3.7 Intrusion of Storm Water

Although the SWWS is segregated from the storm water drainage system, the division might be compromised. The pipes of the SWWS are situated in the ditches and culverts that form the storm water drainage system. As the segregation between the SWWS and the storm water drainage system is the guarantee against unintended pollutants that have been washed off by the surface water, it is important to keep the SWWS without leaks.

4.4 Storage of Chemicals, Toxic Organic Pollutants and Solvents Handling and storage of hazardous materials are at Thule AB managed by the Hazardous Material Management Plan. Major storages are kept in Bldg. 555, 580, 605, 629, 801, 1391, and 4002.

Handling and storage of hazardous waste at Thule AB is managed by the Hazardous Waste Management Plan (CDRL CEV-15B). Major storages are kept in Bldg. 552, 563, 604, and 935.

The potential of accidental spillage of chemicals that might contaminate the SWWS is where sumps and floor drains are leading directly to the SWWS. In all other cases, the chemicals have to be manually poured or pumped into the drains. Temporary drain covers are used to prevent accidental chemical spills from reaching the SWWS. The covers can be removed for floor cleaning and other activities requiring use of the drain.

4.5 Floor Drains

As mentioned in section 4.2, the only direct drainages into the SWWS from floors outside the dormitories are in Bldg. 107, 118, 236, and 4016. Special interest has to be made to these locations, as they are the only places where accidental release of chemicals can occur.

Temporary drain covers are used to prevent accidental chemical spills from reaching the SWWS. The covers can be removed for floor cleaning and other activities requiring use of the drain.

4.5.1 Bldg. 118 – Hospital

There are only floor drains from showers – for both staff and patients.

Thule Air Base, Greenland 11/23 FY-15

All decontamination incidents are handled by the Fire Department in an outdoor mobile emergency system. The system collects all decontamination water for hazardous waste characterization.

As a part of the Environmental Awareness Program at Thule AB (newcomer briefings), all personnel are informed to return expired medical supplies to the hospital or DRMO.

All X-rays are performed with digital computer technology leaving no hazardous waste like mercury, silver, formaldehyde etc.

4.5.2 Bldg. 107 – Dundas Buffet Restaurant

In the kitchen in Bldg 107 several floor drains are installed. From the floor drains, water is directed to a grease trap, where grease and other low-density liquids with low solubility in water can be withheld. The water is subsequently discharged to the SWWS.

4.5.3 Bldg. 4016 – Power Plant, J-site

Storage of petroleum, oil and lubricants (POL), and hazardous materials at the auxiliary power plant at J-site is located in a room with a sump drained directly to the SWWS. The waste is stored in four 55-gallon steel and plastic drums situated horizontally and with secondary containment to collect spillage of chemicals.

4.5.4 Bldg. 236 – TOW Club

Water discharged to the SWWS through the floor drains in the kitchen is also led through a grease interceptor.

4.6 Conclusion

The SWWS at Thule AB is situated above the ground. At the same time, it is totally segregated from the storm water drainage system. Hereby eliminating that outdoor spills of chemicals, POL and other contaminants might run off into the SWWS – except for the possibility that it might enter through a leakage during the short period, where the storm drains are flooded and thereby partly submerging the SWWS.

Thule Air Base, Greenland 12/23 FY-15

5 SLUG MANAGEMENT AND OPERATIONS

Based on the analyses in section 4, the following management and operation plan is established.

5.1 Discharge Practice and Non-routine Batch Discharges

The main risk of damaging the SWWS or the recipient comes from the different routine discharges and non-routine batch discharges.

5.1.1 Discharge practice for trucked and hauled waste

According to the FGS, C4.3.2.1.7: “The discharge of trucked and hauled waste into the DWTS, except at locations specified by the DWTS operator is prohibited”.

As there is no wastewater treatment plant on Thule AB, the only function responsible for the SWWS is GC Utilities and Facilities Maintenance. As such, GC Utilities and Facilities Maintenance has the right to specify discharge of trucked and hauled waste. To prevent damage on the environment beside wastewater all discharges of trucked and hauled waste have to be done after consultation with GC Environmental Engineering.

The FGS, Chapter 4.3.3 includes the general requirements for the discharged batch. GC Utilities and Facilities Maintenance must retain records of the discharge for three years.

5.1.2 Discharge practice for trucked sanitary wastewater

As mentioned in paragraph 4.2, an amount of the collected wastewater is not transported by the SWWS but by truck to Bldg. 984, where it is discharged into the SWWS by the grit system. The same procedure is used for materials collected from septic tanks.

There is no limitation on the amount of trucked wastewater and no record has to be made, as long as the discharge is measured as a part of the ongoing registration of wastewater.

5.1.3 Intentional non-routine batch discharge

Intentional non-routine batch discharges, e.g. when water from a boiler is discharged due to maintenance, are recorded IAW GC Utilities and Facilities Maintenance instructions.

5.2 Handling of Chemicals and Control of Toxic Organic Pollutants and Solvents Hazardous Material Management Plan and Hazardous Waste Management Plan (CDRL CEV- 15B) govern handling of hazardous substances.

5.2.1 Rooms with floor drain directly to the SWWS

In areas with a floor drain and storage of hazardous substances or POL, the rules outlined in the Spill Prevention and Response Plan have to be observed. Temporary drain covers are used when chemicals may spill. The covers can be removed for floor cleaning and other activities requiring use of the drain.

5.2.2 Rooms with floor drain indirectly to the SWWS

In some areas, water from floor drains is pumped to the SWWS. In case a spill occur during pump operation, the pump must be stopped immediately and spill response initiated.

Thule Air Base, Greenland 13/23 FY-15

5.3 Buildings, Containment Structures and Equipment

5.3.1 Planning of new building, containment structures and equipment When planning a new building, containment structures and equipment, it is essential to ensure no spill is directed to the SWWS. The measures are:

• To plan buildings for storage of pollutants in a way with no direct outlet to the SWWS.

• To locate showers, toilets and other drains in building areas, where no pollutants are stored.

• To establish secondary containment for pollutants stored in areas with floor drains.

• To secure floor drains by installing a pump system, that can be manually stopped in case of an accident.

To secure that a proper measure has been chosen, all projects have to be reviewed by GC Environmental Engineering.

5.3.2 Inspection and Maintenance of the SWWS

Inspection and maintenance of the SWWS is the responsibility of GC Utilities and Facilities Maintenance and part of the maintenance program at Thule AB.

The maintenance of the SWWS is important as the segregation between the SWWS and the storm water drainage system is a major part of the safety measures against pollution of the SWWS with spilled materials.

5.3.3 Oil/water Separators

The discharge of petroleum oil, non-biodegradable cutting oil, and products of mineral oil origin is prohibited. In places where oil is removed from objects with water and soap, e.g. where cars are washed, an oil/water separator system has been installed to withhold the oil and non-emulsifying soap (Masava) is applied for the washing process.

GC Utilities and Facilities Maintenance is responsible for the maintenance of the oil/water separators.

Maintenance of oil water separators involves draining them and cleaning them. The drained liquid is collected by a mud pump and left for evaporation on a weathering bed. The weathering bed is located near the land farm area in the western part of the main base area. The bed consists of an earth dike with a liner to protect the surroundings from leaking.

If solid and semi-solid sludge is present in the oil water separator it will be disposed of via the

DRMO.

5.3.4 Sand/Grease Traps

The discharge of solid or viscous pollutants that might obstruct the SWWS is prohibited.

GC Utilities and Facilities Maintenance is responsible for the maintenance of the sand/grease separators.

Thule Air Base, Greenland 14/23 FY-15

5.3.5 Cross Connections

Cross connections between the SWWS and the drinking water system is a problem related to drinking water. The Backflow Prevention Program includes control and removal of cross connections in accordance with AFI 32-1066, and is not a part of this plan.

5.4 Accidental Spill Prevention

As many times previously mentioned the backbone of spill prevention in relations to the SWWS is the segregation. A description of correct handling of hazardous materials is stated under 6.2, but there are other types of unwanted materials as listed in FGS Chapter 4.3.1, 4.3.2 and 4.3.3.

From the perspective of the SWWS, they have to be treated like hazardous substances.

More information on accidental spill prevention is included in the Hazardous Waste Management Plan (CDRL CEV-15B) and the Spill Prevention and Response Plan (CDRL CEV-15C).

5.5 Emergency Response

Emergency Response procedures are included in the Spill Prevention and Response Plan

(CDRL CEV-15C).

Non-routine discharge of wastewater is approved by GC Environmental Engineering.

5.6 Employee Training

GC personnel and non-GC employees who handle hazardous substances or perform activities that could contribute to spill or batch discharges should be trained in appropriate Best Management Practices by the individual shop. Such training should emphasize pollution prevention, awareness of possible pollution sources and local measures to contain spillage in a way that makes it possible to contain the spillage, e.g. how to stop pumps that discharges water from floors into the SWWS.

GC Environmental Engineering training programs include:

• Hazardous Waste Handling, in accordance with “Hazardous Waste Management Plan

(CDRL CEV-15B)”

• Chemical Hazard Communication, in accordance with “Hazardous Material Plan”

• Spill Response Training, in accordance with “Spill Prevention & Response Plan (CDRL

CEV-15C)”

Scheduled training dates are communicated through GC’s Personnel Department, and sign up is available for everyone through GC’s intranet.

The individual participant will receive a certificate from GC Environmental Engineering. GC Environmental Engineering will keep a record of the training for 3 years.

5.7 Sludge Disposal

A wastewater treatment plant is not been installed at Thule AB, therefore, no wastewater treatment sludge is produced.

Thule Air Base, Greenland 15/23 FY-15

6 SEWAGE SPILL/RELEASE INCIDENTS

6.1 Response

All Thule AB personnel are obligated to notify the Consolidated Communication Center or CCC (GC/LGCM) immediately in case of a sewage spill/release to the storm water drainage system.

The Consolidated Communication Center provides the dispatch to Service Call (ext 2111).

When the sewage spill/release incident is non-reportable (below 110 gallons), the Consolidated Communication Center immediately activates:

• GC Utilities Facilities Maintenance (GC/OMUFM)

• GC Environmental Engineering (GC/EE)

If the sewage spill/release incident is reportable (110 gallons or above), the Consolidated Communication Center will also notify location and volume of the sewage spill/release by telephone or pager to:

• GC Site Manager (GC/CC)

• GC Operations Manager (GC/OPS)

• GC Base Civil Engineer (GC/CE)

• GC Chief of Environmental Engineering (GC/EE)

GC Utilities Facilities Maintenance acts as first responder and is tasked to:

• Stop or minimize the sewage spill/release.

• Confine the sewage spill/release.

• Coordinate with GC Environmental Engineering to estimate volume of sewage spill/release.

• Request GC Transportation for assistance to remove and transport any sewage spill/release remains to the effluent building (bldg. #984) at DeLong Pier.

• Repair damaged heat-tracing system, pipes and assemblies.

• Evaluate existing maintenance procedures in the Preventive Maintenance Program

(PMP).

• Assist GC Environmental Engineering in identifying possible root causes.

6.2 Notification of USAF

GC Environmental Engineering is tasked to notify and report sewage spill/release incidents to

USAF.

Upon discovering a sewage spill/release incident the 821 SPTS/CE must be notified within 15 minutes via phone call. If 821 SPTS is unavailable GC Environmental Engineering will call 821 ABG/CC and/or 821 ABG/CD until one of them is contacted.

If the sewage spill/release incident is considered reportable (110 gallons or above), GC Environmental Engineering must prepare and submit an initial spill/release report (CDRL CEV-

19) within 18 hours of discovering the incident. Additionally, an OPREP-3 BEELINE 7C report must be prepared and coordinated with 21 CES/CEIE, if 10,000 gallons or above.

Thule Air Base, Greenland 16/23 FY-15

Reportable sewage spill-release incidents are divided into four (4) categories:

• Category 1: Spill-Release >10,000 gallons

• Category 2: Spill-Release 1,000-10,000 gallons

• Category 3: Spill-Release 110-1,000 gallons

• Category 4: Spill-Release, the Installation Commander (821 ABG/CC) deems necessary to investigate

Sewage spill/release incidents below 110 gallons are considered non-reportable, and no initial spill/release report (CDRL CEV-19) is required. Instead, GC Environmental Engineering prepares spill/release memos for internal recording. These memos are available upon request.

6.3 Non-Routine Discharge of Sewage

Intentional non-routine discharge of sewage is required when heat-tracing system, pipes and assemblies must be repaired or maintained, and harsh arctic weather conditions do not leave any other option.

Intentional non-routine discharge of sewage must be approved by GC Environmental Engineering prior to discharge. The responsible GC/OMUFM supervisor will justify scope of work and fill in a Non-Routine Discharge of Sewage Form.

Thule Air Base, Greenland 17/23 FY-15

7 EFFLUENT MONITORING

The daily volume of direct effluent discharge from Bldg. 984 to North Star Bay is monitored by an open channel flow meter based on standardized Venturi flume principles. The flow meter was installed in January 2009.

The daily volume of direct effluent discharge from Bldg. 4002 (12 SWS) to Wolsteinholme Fjord is monitored by an on-line flow meter based on inductive measure principles. The flow meter was installed in summer 2012.

IAW FGS, Table C4.T2, sampling of effluent is performed monthly at Bldg. 984 and 4002. Grab samples are collected manually.

IAW FGS, Paragraph C4.3.1.3 the monthly collected effluent samples are tested for conventional pollutants as pH, Total Suspended Solids (TSS) and Biochemical Oxygen Demand

(BOD5).

IAW FGS, Paragraph C4.3.1.4 the records on date, time and exact place of sampling and testing, analyst, test results, procedures and daily volume are retained for at least 3 years.

Thule Air Base, Greenland 18/23 FY-15

8 WATER POLLUTION COMPLAINTS

In general, USAF remains current with Greenland environmental activities and regulations IAW Statement of Work, Paragraph 18.11.

All official environmental correspondence sent to organizations outside of the 21 SW is approved by 821 ABG/CC and 21 CES/CEIE prior to release. In addition, copies of all official incoming environmental correspondence are forwarded to 821 ABG/CC and 21 CES/CEIE within five days of receipt.

IAW FGS, Paragraph C4.3.1.5 and C4.3.2.2, water pollution complaints from individuals or host nation water pollution control authorities are investigated, involving the Environmental Executive Agent, as appropriate.

All correspondence and investigations are documented and records are retained for 10 years.

So far, no complaints are received.
