Scope Title

Integrated Waste Management

Context

Rössing as a firmly established company must have integrated waste management programme to direct different waste streams in terms of temporary storage and, eventually, final disposal. In the past waste management was not truly integrated. Whereas domestic waste was disposed of at the Landfill Site, now there is a possibility to take it offsite and eventually close down the Landfill Site. Whereas the luggerbin services have been carried out by different Service Providers, this scope seeks to combine all the services and have them delivered by a single Service Provider. And whereas in the past Rössing provided some equipment and machinery to Service Providers, this revised scope aims to request the Service Providers to provide their own. It also aims to tap into the Service Provider’s expertise in terms of current and best practice relating to HSE and waste management, i.e. the Service Provider must advise Rössing as to the latest waste management methods and strategies in order to better manage the various waste streams.

Purpose

The purpose of this scope is to guide in a rounded and integrated manner the various waste streams by managing their flow to temporary storage and final disposal destinations. The ultimate aim is to comply both with own waste management rules and regulations as well as with national legislation and international agreements and best practices in the waste management space.

2.2.2 Collection and disposal of non-recyclable waste (see Annexure 1 for Procedure

JE50/WMP/001, Procedure JK65/PRD/003, and Procedure JK65/PRD/007)

Most areas on site have lugger bins for their waste collection. Some areas share lugger bins, for example

office buildings. These lugger bins are colour-coded for the different types of waste to be disposed in them.

The disposal requirement of each type of waste is explained in detail in the procedures mentioned above.

The table below shows waste types and their disposal areas. Lugger bins are collected by the “garbage

truck”, emptied and returned to the area where they came from on a weekly basis. The activities include

weighing of waste and reporting of incorrect waste segregation and are scheduled for one specific day of

the week.

2.2.3 Management of waste oils (see Annexure 1 for procedure JE50/WMP/002)

Used hydrocarbons in the work areas are discarded into empty 210L drums. These hydrocarbons are

stored in the used oil temporary storage yard (radioactively uncontaminated hydrocarbons), and next to

rodmills in the processing area (radioactively contaminated hydrocarbons).

Drums are brought to these yards by mine personnel or prior arrangements can be agreed upon between

mine personnel and yard supervisor. The used oil temporary storage yard is opened for storage of drums

for 2 (two) days in a week.

The following is required for waste oil management:

• Ensure that no drums are accepted at the yard that are not clearly labelled with the area name and

content, cleaned, and sealed.

• Arrange with Procurement for the removal of used oil for recycling.

• Arrange with the Municipality of Walvis Bay hazardous waste (or alternative) site in advance when a

load of non-recyclable hazardous waste (including hydrocarbons, fluorescent tubes, etc.) can be

expected to ensure that there are encapsulation cells available.

• Arrange with Wesbank (or any suitable and applicable transport company) for the transport of the

non-recyclable hazardous waste to the Walvis Bay Municipality Hazardous waste site. After disposal

a waste manifest and disposal certificate clearly stating the volumes and tons disposed shall be

submitted to the Environmental Section. Wesbank Transport will bill Rössing directly under the

existing transport contract for the waste transport services rendered. Rössing will enter into a

transporting contract with any appropriate and qualifying transport company.

• Provide final quantities of total weight of loaded drums to the Environmental Section.

• Submit a copy of the certificates of disposal to the Environmental Section.

• Inspect and maintain the condition of the yard. Good housekeeping is of utmost importance.

2.2.4 Management of bioremediation facility (sludge farm) (see Annexure 1 for procedure

JE50/WMP/014, chapter 6)

This activity includes the removal and treatment of all oil sludge from workshop sumps and other oil/diesel

contaminated ground to be removed from site.

• The site supervisor is responsible for inspecting the area to ensure that the bioremediation facility

(sludge farm) is operated according to the procedure and operating conditions are maintained as

specified.

• The site supervisor ensures that oil sludge is removed on a scheduled basis and that the necessary

equipment is readily available.

• The site supervisor also notifies the Tailings Operations Foreman before the delivery of contaminated

sludge/soil to the sludge farm.

• Delivery and mixing of sludge - The delivery procedure depends on the water content of the oil

sludge. Generally wet sludge pumped from oil sumps is delivered in a special vehicle and discharged

from a ramp at the sludge farm. The sludge is left to dry until most of the water has evaporated. The

operator then removes any foreign material. The material collected from the sludge is taken to the

contaminated waste site on the Tailings Dam. The sludge is spread out in a layer of about 200mm

and fertiliser/ Bio remediation chemicals is applied. The sludge layer is mixed with the underlying soil

to achieve a total thickness of the treatment layer of 300mm.

• Dry contaminated soil or sludge is transported in open trucks and dumped directly onto the treatment

area. Spreading, mixing and fertilising/adding bioremediation chemicals are carried out as described

above.

• Moisture addition - While micro-organisms can tolerate a wide range of soil moisture, they are most

active at higher moisture contents. The soil moisture should be adjusted at process commissioning

and then controlled within the target range of 70-80% of field capacity (field capacity is the amount of

water a soil can hold). The sludge should not be allowed to dry out at any time. At low soil moisture

the micro-organisms are inhibited or even destroyed. Higher moisture contents exceeding 80% of

field capacity should also be avoided as soil pores filled with water keep out oxygen.

• Nutrient addition - The soil at the sludge farm is nutrient deficient such as nitrogen (N) and

phosphorus (P). The addition of hydrocarbons increases the imbalance between carbon (C), N and P.

Under most conditions a C:N ratio of 10-30:1 is recommended, and an N:P ratio of 5-10:1. The N and

P demand is calculated from the hydrocarbon content of the sludge. Agricultural water-soluble or

slow-release fertilisers such as Urea or MAP (Mono - Ammonium Phosphate) can be applied. The

initial sampling results showed that the current type of sludge needs 50 kg of Urea every two months.

• Soil mixing and aeration - The soil must be mixed regularly for aeration, as most micro-organisms

thriving on hydrocarbons require oxygen. Mixing is achieved either by hand or with a rotary cultivator.

The whole treatment layer should be mixed, but not compacted. The soil should not be mixed

immediately after irrigation or rainfall. The frequency has to be determined during operation. An initial

weekly frequency is recommended and should be reviewed after 6-8 weeks.

• Soil pH - The pH of the contaminated soil has to be determined after the material has been delivered

to the bioremediation facility (sludge farm). It should be in the near neutral range of 6-8. If it is lower

or higher, lime or sulphur can be added to adjust the pH. The pH is determined by putting a small

amount of soil into a sample container and mixing it with tap water. The pH of the solution is

measured with a portable calibrated pH meter.

2.2.5 Operation of hydraulic press for both oil and air filters (see Annexure 1 for Hydraulic Press

Operating Procedure)

The Contractor, shall provide their own hydraulic press or come up with an alternative method of flattening

or pressing the oil and air filters to prepare these for disposal at the TSF.

This activity covers all oil filters for vehicles, gearboxes, transmission, hydraulic systems, etc. Whenever

maintenance is carried out on any vehicle/equipment at the maintenance workshop or in the field, the

oil/diesel filters need to be changed. The oil/diesel filters should be drained (filters taken out in the field

should be taken to the workshop) in an oil drip tray for at least 24 hours. After this draining period, the filter

is disposed of into the brown lugger bin provided for this purpose.

Activities include

• Collection of brown lugger bin from the area

• Putting all filters through the available hydraulic press (18 ton, double acting hydraulic press) to

reduce size.

• Once pressed, obtaining radiation clearance in order to take filters off-site for recycling.

• If radiation reading is too high, clearance will be rejected and filters should be disposed of at the

contaminated waste yard on the Tailings Storage Facility.

2.2.6 Operation of road sweeper and honey sucker

• The Contractor will provide own road sweeper and put it on a schedule to operate during weekdays.

The sweeping schedule is shown below. Operation includes the disposal of swept dust at the

contaminated waste site on the tailings storage facility and arranging for all daily and scheduled

maintenance activities.

Monday Radioactively contaminated areas at Processing and Mining

Tuesday Fine crushing and Occupational health section and contractor yards

Wednesday Engineering workshops and Stores

Thursday CMC and other Processing areas

Friday Mine maintenance, Mining engineering and Transport centre

• The “honey sucker”, to be supplied by the Service Provider, will be used to empty wash down sumps

in the workshop areas. This machine will be operated on an ad hoc or on demand basis for four hours

per week. As part of the operation the machine needs to be emptied at the oil separation plant. This

piece of equipment, like any other equipment owned by the Service Provide, must be subjected to

regular maintenance as per C3 Standard.

2.2.7 Ad hoc waste management tasks

Description of ad hoc waste:

During times of non-routine maintenance work large amounts of waste is generated. Ad hoc waste may

include tanks, pipes or any other bulky material that do not fit in lugger bins. The Contractor is responsible

for planning and coordinating, with co-operation of the company representative, regarding the handling and

disposal of such waste. The Planning Section of the Maintenance Department will involve the Waste

Management Contractor during the planning and execution of any non-routine maintenance work where

large amounts of waste will be likely generated. This may include activities during

o project related work (Projects)

o weekly shutdowns (module days)

o and breakdowns

Quality

Testing and Quality Management

A quality assurance and quality control management program must be provided for by the Contractor and

approved by the Engineer and Employer on establishment prior to kick off.

It will be the full responsibility of the Contractor to undertake appropriate quality control and quality

assurance measures on site. The Engineer shall audit the Contractor’s QA system on a regular basis to

ensure that adequate independent checks and test are being carried out and to ensure that the contractor’s

own controls are sufficient to identify any possible quality problems which could cause a delay on the

programme.

The contractor will ensure that, at a minimum, quarterly scheduled HSE audits are conducted internally and

where required reviewed and confirmed by a third party auditor. All audit reports must be submitted to the

Engineer. It is up to the discretion of the Engineer to call for an audit at any appropriate time, outside of the

normal audit schedule.

Reporting

In order to carry out an optimised waste management function and to conform to internal standards, it is

required that comprehensive measuring and reporting of all waste streams are carried out. The contractor is

required to report the following on a monthly and annual basis.

• Waste source; • Waste type handled;

• Volume and weight of waste handled;

• Weight of recyclable waste taken off site; • Point of disposal;

• Equipment hours;

• Consumables used; • Maintenance carried out;

• Any other statistics or client specific requests that will be required from time to time. The Designated Rössing representative (DL) will capture this information in the Rössing SAP system.
