In recent years, illegal dumping of hazardous waste has been repeatedly exposed, leading to numerous chemical enterprises being brought to court and ordered to pay substantial environmental remediation costs. As the Yangtze River basin is home to a dense concentration of chemical plants, pollution levels there have grown increasingly severe. In response, the state has introduced a series of environmental protection policies, and environmental inspection teams have conducted thorough audits of chemical enterprises along the riverbank. Nevertheless, safeguarding the Yangtze remains a long and arduous task. As early as April this year, the Ministry of Ecology and Environment launched “Operation Clean Waste 2019,” targeting illegal activities involving solid waste, with the aim of curbing the discharge of hazardous and solid waste along the river and protecting the Yangtze. |

3. The liner shall be placed on a foundation or base; it must be capable of covering the area potentially affected by hazardous waste or its leachate; the liner material must be compatible with the hazardous waste being stored; and a leachate collection and removal system shall be designed and constructed on top of the liner.
4. Hazardous waste piles shall be protected from wind, rain, and sunlight.
5. Hazardous wastes of the same type stored in containers may be stacked; a handling aisle shall be provided between each stack.
04 Storage Management
Inspection content:
1. Is there a hazardous waste ledger, and, in conjunction with this ledger, verify whether the types, quantities, and disposal methods of the enterprise’s hazardous waste are consistent with those specified in the environmental impact assessment?
2. Hazardous Waste Transfer Manifest (whether the hazardous waste transfer plan has been approved, and whether the enterprise has accurately completed the “Generating Unit” section of the manifest and affixed its official seal)
3. Has a sound system for the prevention and control of hazardous waste pollution been established? Are the responsible persons clearly designated with well-defined responsibilities, and are they familiar with the relevant laws, regulations, systems, standards, and specifications governing hazardous waste management?
4. Are hazardous wastes transported in a timely manner?
5. Status of locking the hazardous waste storage facility.
Image example:

|
Key points of the standard:
1. Both hazardous waste generators and operators of hazardous waste storage facilities are required to maintain records of hazardous waste, which must include the waste’s name, source, quantity, characteristics, the type of packaging container, date of receipt, storage location, date of dispatch, and the name of the receiving entity. Such records and accompanying manifests shall be retained for a period of three years following the return of the hazardous waste.
2. The hazardous waste storage room shall be managed in accordance with the “dual‑person, dual‑lock” system. (The two keys shall be held by two designated hazardous waste managers; no single individual may hold both keys.)
3. Hazardous waste shall not be stored for more than one year; if storage exceeds one year, approval must be obtained from the environmental protection authority.
05 Safety Protection of Storage Facilities
Inspection content:
1. Are hazardous waste storage areas equipped with hazardous waste warning signs and labels, and are these signs accurate, clear, and intact?
2. Are the hazardous waste storage facilities equipped with emergency protective equipment, fire-fighting facilities, and other such measures?

If interprovincial transfer is required, a hazardous waste transfer manifest must be completed. The manifest consists of five copies:
After the first and second copies of the joint form are completed, they shall be affixed with the official seal, submitted to the transportation unit for signature and verification, and then retained on file by the submitting party.
After the second copy is completed by the generating unit, stamped with the official seal, and verified by the transport unit through signature, it shall be submitted to the local environmental protection administrative authority for filing.
The second copy of the auxiliary certificate is handled in the same manner as the first, with the generating unit submitting it to the environmental protection authority at the place of departure for archival purposes.
The third copy of the document is handled in the same manner as the first and is filed by the transporting unit.
The fourth copy is handled in the same manner as the first and shall be filed by the receiving unit.
The fifth copy shall be handled in the same manner as the first, and shall be filed by the environmental protection authority of the receiving locality.
The retention period for the manifest is five years; for hazardous waste, the retention period of the manifest shall be the same as the storage period for such hazardous waste.
Summary
Environmental inspections are becoming increasingly stringent, and news of chemical companies and industrial parks relocating along the Yangtze River is mounting. Yet the path to remediation remains fraught with challenges. First, legacy pollutants have yet to be fully addressed, while new sources of contamination continue to emerge. Second, many enterprises still rely on production processes that generate substantial hazardous waste. Relying solely on relocation or setting distance requirements addresses symptoms rather than root causes; even if facilities move away from the Yangtze, they may simply displace pollution elsewhere. The “2019 Waste Cleanup Campaign,” which spans 11 provinces and 126 cities, not only seeks to standardize hazardous‑waste discharge and production practices among riverside chemical firms but also aims to achieve comprehensive environmental remediation to safeguard the Yangtze’s waters. Riverside chemical companies should take note: a mechanism for monitoring and managing solid waste will soon be put in place—so act quickly to comply with these new requirements.
