reclamation, the activity of utilizing non-hazardous industrial solid waste to replace soil, sand,

stone and other production materials to fill underground goal spaces, open-pit mining surface

excavation areas, borrow pits, underground mining subsidence areas and natural potholes.

3.12 native foundation

The undisturbed rock and soil layer located under the anti-seepage liner.

4.6 The above provisions on site selection do not apply to the mining with backfilling and

backfilling of non-hazardous industrial solid waste.

5.1 General Provisions

5.1.1 In accordance with different technical requirements for pollution control on construction,

operation and closure, etc., the storage and landfill facilities are classified into Class I and Class

II facilities.

5.1.2 The flood control standards of the storage and landfill facilities shall be designed in

accordance with the flood level with a recurrence interval of not less than 50 years, unless the

national standards have proposed higher requirements.

5.1.3 Generally speaking, the storage and landfill facilities shall include the following units.

5.1.4 The construction schemes for the storage and landfill facilities shall include construction

quality assurance and construction quality control, clarify environmental protection clauses and

responsibilities, and serve as the basis for environmental protection acceptance upon

completion of the project. Meanwhile, they may also be used as the main content of construction

environmental supervision.

5.1.8 For non-hazardous industrial solid waste with properties similar to domestic waste

generated in activities that provide services for daily life, such as. food manufacturing, textile

clothing and apparel industry, paper making and paper products industry, agricultural and

sideline food processing industry, etc., as well as non-hazardous industrial solid waste (except

coal gangue) with an organic matter content exceeding 5%, the direct storage and landfill

disposal shall comply with the requirements of GB 16889.

5.2 Technical Requirements for Class I Non-hazardous Industrial Solid Waste

Storage and Landfill Facilities

5.3 Technical Requirements for Class II Non-hazardous Industrial Solid Waste

Storage and Landfill Facilities

5.3.1 Class II non-hazardous industrial solid waste storage and landfill facilities shall adopt a

single composite liner system as the anti-seepage liner and comply with the following technical

requirements.

5.3.2 The surface of the foundation layer of Class II non-hazardous industrial solid waste

storage and landfill facilities shall be kept at a distance of more than 1.5 m from the annual

highest groundwater level. When the distance between the surface of the foundation layer of

Class II non-hazardous industrial solid waste storage and landfill facilities and the annual

highest groundwater level is less than 1.5 m, a groundwater drainage system shall be

constructed. The groundwater drainage system shall ensure that the groundwater level is

maintained 1.5 m below the surface of the foundation layer during the operation period of Class

II non-hazardous industrial solid waste storage and landfill facilities.

6.1 Non-hazardous industrial solid waste entering Class I non-hazardous industrial solid waste

storage and landfill facilities shall simultaneously satisfy the following requirements.

6.3 Non-hazardous industrial solid waste specified in 5.1.8 can only be stored and landfilled in

Class II non-hazardous industrial solid waste storage and landfill facilities after being treated

and satisfying the requirements of 6.2.

6.4 Incompatible non-hazardous industrial solid waste shall set up different partitions for

storage and landfill operations.

7.2 The storage and landfill facilities shall develop operation plans, and operation management

personnel shall regularly participate in enterprise on-the-job training.

7.4 The graphical signs for the environmental protection of the storage and landfill facilities

shall comply with the provisions of GB 15562.2 and shall be regularly inspected and maintained.

7.5 The storage and landfill facilities that may easily generate dust shall take effective dust

suppression measures, such as. zoning operations, covering and water sprinkling, etc., to

prevent dust pollution. Tailings ponds shall take measures, such as. uniform ore drawing and

water sprinkling, etc. to prevent dust pollution from dry beaches.

7.6 Pollutant emission control requirements

8.2 For Class II non-hazardous industrial solid waste, as well as Class I non-hazardous

industrial solid waste that does not comply with the mining with backfilling or backfilling ways

in 8.1, before the mining with backfilling or backfilling activity, an environmental background

survey shall be carried out. In addition, in accordance with the relevant standards, for example,

8.3 No other solid waste other than additives required for the mining with backfilling operation

shall be added to the filling materials.

8.4 After the backfilling operation of non-hazardous industrial solid waste is completed, land

reclamation shall be immediately implemented (except underground backfilling), and land

reclamation shall comply with the provisions of 9.9 of this Standard.

8.5 For non-hazardous industrial solid waste with properties similar to domestic waste

generated in activities that provide services for daily life, such as.

9.1 When the service period of the storage and landfill facilities expires or they no longer

assume new storage and landfill tasks, closure operation shall be initiated within 2 years, and

corresponding pollution prevention and control measures shall be taken to prevent

environmental pollution and ecological damage. The closure plan can be implemented in phases.

The closure time and process of tailings ponds shall also comply with the relevant

administrative regulations and management regulations on closure.

9.5 After closure, it is still necessary to maintain and manage the covering layer, so as to prevent

uneven settlement and cracking of the covering layer.

9.6 Markers shall be set up in the storage and landfill facilities after closure to indicate the

closure time and matters that shall be paid attention to when using the land.

9.7 After closure, the leachate treatment system and wastewater discharge monitoring system

shall continue to normally operate, until no leachate is generated for 2 consecutive years or the

leachate generated can be stably discharged and up to standards without treatment.

9.8 After closure, if the non-hazardous industrial solid waste needs to be mined and re-utilized,

an environmental impact assessment shall be conducted.

9.10 Once a historical storage facility of non-hazardous industrial solid waste has been assessed

to ensure that the environmental risks are acceptable, closure or land reclamation operations

can be carried out.
