surface water and groundwater. The site shall have a stable
foundation and two impermeable liners with leachate
collection and removal systems. Precipitation runoff from

D-11
MP-LSTK / MP-IK-LSTK / MP-IK-LSPB 04/13
SCHEDULE “D” CONTRACT NO. 66000XXXXX
SECTION II
surrounding areas shall be diverted away from the site. A
Class I landfill disposal site shall be used for the disposal of
Class I hazardous wastes and may be used for the disposal
of Class II biodegradable and chemically decomposable
wastes and Class III inert wastes. Class I landfills shall only
be operated by qualified environmental contractors that are
licensed by the Presidency of Meteorology and Environment
(PME).

7.5.1.2 Class II Landfill Disposal Site - shall be above the highest

groundwater elevation to prevent direct contact of the
wastes with surface water or groundwater. The landfill site
shall have a stable foundation and provisions shall be made
for diversion of runoff. A Class II landfill disposal site shall
be used for Class II wastes and may be used for Class III
wastes.

7.5.1.3 Class III Landfill Disposal Site - provides little or no

protection from underlying groundwater. Surface water
adjacent to the disposal site may contact the waste material.
A Class III disposal site is for the disposal of Class III inert
waste only.

7.5.2 Waste classification will be according to the following:

Class I Hazardous Waste - Wastes which constitute a high degree

of hazard to the public health and the environment. These include
materials which are flammable, corrosive, reactive, toxic, radioactive,
infectious, carcinogenic, mutagenic or teratogenic. Wastes listed as
hazardous waste in PME’s Rules for Implementation and in the
SAUDI ARAMCO Hazardous Waste Code, shall be considered
Class I waste.

Class II Biodegradable or Chemically Decomposable Waste - Non-

hazardous solid wastes and sludges which are biologically or
chemically decomposable in the natural environment. Examples
include paper, digested and dried sewage sludge, animal wastes,
garbage and other putrescible wastes and wood.

Class III Inert Wastes - Wastes which are not biologically or

chemically active in the natural environment. Examples include
glass, most plastics, rubber products and construction debris.

waste shall be confined to as small an area within which equipment
can safely and efficiently operate.

7.6.2 Unauthorized Dumping - Provision shall be made to restrict access

and dumping of unauthorized material. This includes overboard
dumping of construction debris or refuse from offshore construction
activities.

7.6.3 The Company Representative will advise on problematic waste, as

required, and provide disposal instructions.

7.6.4 Incompatible Wastes - Incompatible wastes shall not be placed in

common cells, tanks or containment areas. Exceptions to this
include the intentional combination of certain hazardous wastes to
achieve neutralization and detoxification by qualified waste
management personnel.

7.6.5 Sludge Disposal - Dried sludge from domestic wastewater treatment

plants shall be disposed in a Class II waste disposal site. The sludge
shall be placed over the working face (the area of a landfill in which
waste is currently being deposited) and shall be mixed in an
appropriate ratio with dry waste to absorb moisture.

7.6.6 Environmental/Water Pollution - Landfill operations shall not cause

or allow discharge of contaminants into the environment or adversely
impact surface or groundwater systems.

7.6.7 Waste containing free liquid (i.e., waste that fails the United States
Environmental Protection Agency’s SW-846 Method 9095A: Paint
Filter Liquids Test) shall not be disposed of in landfills.

7.6.8 All shipments of hazardous waste shall be manifested in accordance
