Section III. PROCEDURES FOR SHUTDOWN OF DOMESTIC SOLID WASTE LANDFILLS

Article 21. Procedures for shutdown of domestic solid waste landfills

1. A sanitary domestic solid waste landfill shall be shut down in the following cases:

a) The domestic solid waste landfill has reached its capacity approved by the competent authority;

b) The domestic solid waste landfill owner fails to keep operating the domestic solid waste landfill and fails to transfer the domestic solid waste landfill;

c) The domestic solid waste landfill is shut down at the request of the competent authority.

2. 10 working days before the shutdown of the landfill, its owner shall send a notification of the date of shutdown to the provincial specialized environmental protection authority.

3. Procedures for shutdown of a domestic solid waste landfill:

a) The domestic solid waste landfill must have a topsoil covered with clay or HDPE plastic or equivalent material of over 30%, ensuring that it maintains standard humidity and is carefully compacted with a thickness greater than or equal to 60cm. The slope from the foot to the top of the landfill is between 3% and 5%, ensuring proper drainage, no landslide and subsidence. The following activities should be carried out:

- Cover the liner consisting of sand with a thickness of 50 to 60 cm;

- Cover the soil layer with a thickness of 20 to 30 cm;

- Grow grass and green trees;

b) If the domestic solid waste landfill has multiple cells, it is required to close each cell according to the procedures specified in Point a of this Clause;

c) Within 6 months from the date of shutdown of the domestic solid waste landfill, its owner shall submit a report on the status of the domestic solid waste landfill to the authority approving environmental impact assessment reports. The report shall contain at least:

- Operation, effectiveness and capacity of all works in the domestic solid waste landfill, including waterproofing system of the domestic solid waste landfill, leachate collection and treatment system, surface water and groundwater management system, gas collection system, groundwater quality monitoring system and other environmental protection works in accordance with applicable regulations (if any);

- Results of monitoring of quality of wastewater, groundwater and gases from the domestic solid waste landfill;

- Environmental remediation, improvement of landscape of the domestic solid waste landfill and pollution control measures for the coming years;
