STANDARD OPERATIONAL PROCEDURE – WASTE MANAGEMENT (BASED ON
ENVIRONMENTAL QUALITY ACT 1974)
Domestic Waste
Domestic waste or mixed waste is waste generated mainly from everyday activities, like food
remains.
Industrial waste should never be mixed with domestic waste.
Dedicated containers will be used for the collection of domestic waste. These are placed in areas such
as mess rooms and offices which are the major generators of domestic waste.
A clear visible sign shall be affixed to the container showing the waste stream “mixed waste”,
scheduled waste (SW), and drawings of examples of waste pertaining to this waste stream.
Industrial waste has to be classified into various waste streams as per Ministry Department of
Environmental (DOE). Each waste stream is assigned a Scheduled Waste codes.
Scheduled Waste (SW) codes has to be segregated and collected in separate containers. Different
waste codes cannot be mixed. Dedicated signs are to be affixed to each container showing type of
waste.
Industrial waste must be clearly distinguished between hazardous and non-hazardous and such waste
streams are to be properly segregated.
Hazardous industrial waste must always be placed in closed containers, or else covered to avoid
rainwater coming in, and subsequent overflow from the container.
Handling of Waste
Handling of waste is to be carried out in such a way as to minimize risk to human health and to the
environment. In particular, all precautions should be taken in order to avoid accidents that affect:
Soil or water pollution;
Fire or explosion;
Toxic gas generation;
The following are good practices for internal transportation of waste:
Containers containing liquids should always be closed;
Containers carrying solid or liquid waste should be secured to the means of transport being used in
order to avoid any spills of material;
Any waste which has fallen out of the container should be collected immediately.
Waste Storage Areas
Waste storage areas must be correctly planned. The following points should always be observed:
Spills and leakages should be avoided wherever possible, or preferably kept to a minimum.
Skips for hazardous waste should be covered and the site should have suitable containment with
appropriate drainage facilities.
Spills are to be contained and collected such that they do not contaminate soil or water.
Soil or water are not to be polluted by rainwater which is contaminated through contact with waste.
Waste storage areas should be separated and clearly identified.
Each waste unit is to be clearly marked and understood by all operators including those from
transport companies and those collecting waste.
Any hazard risks (flammable, toxic, etc.) should be clearly legible and immediately identifiable.
Chemically incompatible wastes are to be segregated.
Appropriate emergency equipment for first aid, fire and spills should be easily accessible.
In case of hazardous waste, a Safety Data Sheet should be available with the waste.
The Contractor is responsible to provide bins with correct labelling for the duration of works.
Waste generated within PAD premises for any contractor must be disposed of, off site by a fully licensed
carrier as soon as reasonable practicable so as not to accumulate on PAD premises. The responsible
person will ensure that the site is checked that it is properly clean and waste free before the works are
terminated.
Inventory of Scheduled Waste (SW)
The Contractor is to maintain a waste inventory keeping detailed records of all disposal of hazardous and
non-hazardous waste. The Contractor should regularly provide an updated copy of this waste register
together with all weight chits from the waste disposal facility to the responsible person. A copy of any
waste consignment notes should also be submitted in the case of disposal of hazardous waste. These
records should include details about the waste (including the specific SW code) and the weight of the
waste disposed. The final destination of the waste (permitted waste site) is also to be provided, as well as
the number plate of the carrier used to transport the waste to the permitted waste site.
The waste register is to include as a minimum the details below:
Waste Management Facilities and Waste Carriers
At the beginning of the contract, the contractor is to send a copy of the waste register as per section
(above) with a list of waste which are expected to be generated throughout the contract and details of the
waste management facilities where he intends to dispose of such waste. Details of the waste carriers to be
utilized are also to be included. This document is to be submitted by the responsible person to the DOE to
confirm that waste is being disposed of correctly. Any modifications to the waste carriers or waste
management facilities throughout the duration of the contract are to be submitted to the DOE for
approval.
Waste Transport: Consignment Note
1. Hazardous waste
Every time that there is a disposal of hazardous waste, this requires a valid permit from DOE and the
actual transfer of the waste has to be accompanied by a form issued by DOE, called a consignment note.
The consignment note procedure is divided into two stages:
Stage One: Waste Consignment Permit Application (CP)
Stage Two: Waste Consignment Note (CN)
All Waste Consignment Permit Applications (CP) and Waste Consignment Notes (CN) have a unique
number (code) allocated by DOE. The Waste Consignment Permit Application (CP) is used in order to
obtain a permit for the disposal of waste while the Waste Consignment Notes (CN) must be used for the
transfer of waste.
1.1 Waste Consignment Permit Application (CP) and Waste consignment Note application (CN)
When disposing of hazardous waste, it must be ensured that any hazardous waste must not be stored for
more than 1 year. The quantity of waste being generated and the information related to the particular
waste must also be taken into consideration.
A permit is needed for the disposal of each separate hazardous waste stream.
The Waste Contractor used by Contractor (or the Contractor himself if he is a waste contractor) acts as
the CPR. The Waste Contractor will be responsible to fill in the DOE Waste Consignment Permit
application form (CP). Once the permit for the disposal of a particular hazardous waste is issued by DOE,
CPR should fill in the Consignment Note to make arrangements for the disposal of the hazardous waste
generated from work on behalf of PAD.
A copy of the Waste Consignment Permit Application and the Waste Consignment Notes is to be handed
in by the Contractor to the responsible person.
The waste register is to be updated as per section (on the above)
Non Hazardous Waste
Disposal of non-hazardous waste does not need DOE permit. Thus the procedure for the application of a
permit from DOE and the filling in of the official DOE consignment note will not apply in this case.
However for reporting purposes, the waste register still needs to be updated as per section (above). Non-
hazardous waste can be temporary stored on site for a maximum period of 1 year.
