  4. Abandonment & Restoration: 8. Control of Oil Material and Scheduled Waste



Scheduled waste such as oil and grease are generated throughout Project activities. Improper handling of fuel and maintenance of equipment and machinery at the processing site as well as unintentional oil spills and leakages from vessels used for the Project may cause adverse impacts to water quality.


  • Proper handling and storage of oil materials and scheduled waste.
  • Prevention of pollution to soil and water bodies.
  • Minimisation of hazards at the project site.

Standard Operating Procedures

8.1 Oil Material & Scheduled Waste Management (General)

8.1.1 Store all oil materials and scheduled waste in appropriate containers.

8.1.2 Provide information on volume, contents, and safety instructions on the oil containers.

8.1.3 Label scheduled waste containers Refer to Figure 11 extracted from the Guidelines for Packaging, Labelling and Storage of Scheduled Wastes In Malaysia (DOE) for an example of the scheduled waste label.

8.1.4 Appoint a licensed scheduled waste contractor to dispose scheduled waste generated on-site.

8.1.5 Prior to reusing spent oil, written permission shall be obtained from DOE.

8.1.6 Create an inventory to keep track of generated and disposed scheduled waste.

8.2 Oil Material & Scheduled Waste Management (Land)

8.2.1 Construct the oil/scheduled waste storage area at the distance (from any riverbanks or waterways) specified in the AEC.

8.2.2 Avoid locations prone to flooding for the construction of the oil/scheduled waste storage area.

8.2.3 Construct/equip the oil/scheduled waste storage area with the following structural mitigations:

    1. Concrete dike or equivalent structure (surrounding the oil storage area). Build to the capacity of 110% of the largest container stored in the storage area.
    2. Fire fighting equipment
    3. Roofing
    4. Drainage system
    5. Oil trap
    6. Concrete covered floor (or other suitable lining material)

8.2.4 Conduct regular maintenance on the provided structural Collect oil and grease confined within the bund or oil trap into an appropriate container and disposed of as scheduled waste.

8.2.5 Clean up spilt oil/scheduled waste material when When materials are spilt on soil, use a shovel or scoop to transfer the contaminated soil into appropriate containers such as metal drums or polyethylene bags, to be eventually disposed as scheduled waste.

8.3 Oil Material & Scheduled Waste Management (Barge & Pontoon)

8.3.1 Store all oily material on barge or pontoon at an area with shade and equipped with bund/drip The bund/drip pan must be made of metal sheets which could withhold 110% capacity of the stored oil materials. Refer to Figure 15 and Plate 17 for the example of a drip pan and oil storage.

8.3.2 Equip a bund/drip pan with a valve to allow easy removal of collected spilt oil. Dispose the spilt oil from the bund/drip pan structure as scheduled waste.

Figure 15: Example of design and function of a drip pan.

Plate 17: Example of oil storage equipped with drip pan for barge or pontoon.

8.3.3 Prepare an Emergency Response Plan (ERP) for oil spills to ensure immediate action is taken during such events to minimise damage or pollution to the environment.

8.3.4 Spill kit consisting of Personal Protective Equipment (PPE), absorbent materials, and cleaners (e.g., floating boom, absorbent pad, oil skimming sweeps, etc.) should be made readily available to contain accidental oil spillage.

8.3.5 Perform inventory checks and examine the spill kit regularly to ensure the equipment is ready to be used when oil spills occur.

8.3.6 Install boom on vessels to localise oil spills as a contingency plan.

8.3.7 Use absorbent pads or other suitable absorbent material to clean up spilt oil confined within the floating boom.

8.4 Others

8.4.1 All working machinery i.e. dredgers and barges operating within the river should always be in good condition, well-maintained, and free from defects, leaks as well as oil and grease.

8.4.2 Keep a record of the maintenance of machinery and vehicles.

8.4.3 Urgent maintenance required on the barge should be carried out with extra precaution to ensure there is no spillage or leakage of oil substances into the river. Any outlet from the maintenance area should be cleaned by oil absorbent pads to prevent oily water discharge.

8.4.4 Provide contact information of relevant government departments (e.g., fire department, Sabah State Water Department (JANS), DOE, etc.) when oil spills in rivers occur.
