After the implementation of the new Directory, what work needs local ecological and environmental departments and enterprises to do to connect?
After the implementation of the new Directory, what work needs local ecological and environmental departments and enterprises to do to connect?
A: Some hazardous wastes have been added and reduced in the revision of the Directory, and some waste codes have changed, and local ecological and environmental departments and relevant enterprises need to do a good job in linking the implementation of the Directory with environmental management systems such as hazardous waste management plans, transfer coupons, and permits
.
For example:
.
For example:
1) If the type or code of hazardous waste generated by relevant enterprises changes, the hazardous waste management plan and pollution discharge permit and other information
should be changed in time.
should be changed in time.
2) If there is a change in the type and code of hazardous waste in the hazardous waste collection and comprehensive permit, the licensed enterprise and the local ecological and environmental department shall make changes
in a timely manner.
in a timely manner.
3) If there is a change in the type or code of hazardous waste applying for the transfer of hazardous waste across provinces, the relevant enterprise shall change the transfer plan and resubmit the transfer application

What are the main considerations for the revision of the Directory to delete the relevant provisions on medical waste and waste hazardous chemicals (Articles 3 and 4) in the main text?
What are the main considerations for the revision of the Directory to delete the relevant provisions on medical waste and waste hazardous chemicals (Articles 3 and 4) in the main text?
A: This revision is not simply to delete the relevant provisions on medical waste and waste hazardous chemicals in the main text of the List, but to further improve and refine the relevant content and include it in the appendix of the List, which is more scientific and rigorous
.
.
Regarding medical waste, the Law on the Prevention and Control of Environmental Pollution by Solid Waste stipulates that "medical waste shall be managed in accordance with the national hazardous waste list"
.
The Directory no longer simply stipulates that "medical waste is hazardous waste", but lists the relevant types of medical waste in the Appendix to the List, and stipulates that "the classification of medical waste shall be carried out in accordance with the Catalogue of Classification of Medical Waste"
.
.
The Directory no longer simply stipulates that "medical waste is hazardous waste", but lists the relevant types of medical waste in the Appendix to the List, and stipulates that "the classification of medical waste shall be carried out in accordance with the Catalogue of Classification of Medical Waste"
.
Regarding waste hazardous chemicals, the first is to further clarify the scope of waste hazardous chemicals included in the environmental management of
hazardous wastes.
Not all hazardous chemicals in the Catalogue of Hazardous Chemicals have environmental hazard characteristics, and waste hazardous chemicals cannot be simply equated with hazardous wastes, such as "liquid oxygen" and "liquid nitrogen" and other hazardous chemicals
that only have the physical hazard of "pressurized gas".
hazardous wastes.
Not all hazardous chemicals in the Catalogue of Hazardous Chemicals have environmental hazard characteristics, and waste hazardous chemicals cannot be simply equated with hazardous wastes, such as "liquid oxygen" and "liquid nitrogen" and other hazardous chemicals
that only have the physical hazard of "pressurized gas".
Second, it further clarifies the requirements for
the inclusion of waste hazardous chemicals in the environmental management of hazardous waste.
After some flammable and explosive hazardous chemicals are discarded, their hazardous chemical properties do not change; It is also difficult for regulators to define
whether hazardous chemicals are discarded.
Therefore, the Directory specifically proposes "declared for disposal by the owner" for waste hazardous chemicals, that is, the owner of hazardous chemicals should declare the waste to the emergency management department and the
ecological environment department.
The main reason for the "3?21" accident in Xiangshui is that the enterprise has neither stabilized the waste hazardous chemicals into the environmental management of hazardous waste in accordance with relevant national standards, nor declared them to the emergency management department and the ecological environment department, evading supervision and causing major accidents

What are the considerations for the "peer-to-peer" directed use exemption? How is the implementation implemented?
What are the considerations for the "peer-to-peer" directed use exemption? How is the implementation implemented?
A: After the exemption management system was first proposed in the 2016 edition of the List, it has played a positive role
in promoting the utilization of hazardous waste.
However, there are many types of hazardous wastes and diverse utilization methods, and it is difficult to make provisions one by one, and it is necessary for all localities to implement more flexible utilization exemption management in combination with actual conditions to further promote the utilization of
hazardous wastes.
Therefore, the Directory specifically proposes that "under the premise of controllable environmental risks, according to the scheme determined by the provincial ecological and environmental department, the 'point-to-point' directional utilization of hazardous waste" is implemented.
