3. How to verify these companies

To verify the qualifications of hazardous waste enterprises, focus on the following operations: 1. Check the Hazardous Waste Operation Permit - search the enterprise name on the Chongqing Municipal Ecological Environment Bureau's official website under 'Government Services' or 'Public Announcements', and verify the approved hazardous waste categories, scale, validity period, and processes. 2. Check the Pollutant Discharge Permit - log into the public portal of the National Pollutant Discharge Permit Management Information Platform, enter the enterprise name, and see whether it holds the permit and its main pollutant emission indicators. 3. Check EIA and acceptance documents - confirm the project's EIA approval and completion environmental protection acceptance information in the public announcements of the district/county ecological environment sub-bureaus. 4. Check violation records - screen administrative penalties or supervised rectification records through 'Credit China (Chongqing)' or the Ministry of Ecology and Environment's '12369' reporting platform. 5. On-site confirmation - against the original permit, check whether the hazardous waste temporary storage area signs, ledgers, and transfer manifests at the plant site are standardized.

4. What to watch out for

When selecting hazardous waste partners, note the following: First, verify that the permit is within its validity period and that the approved categories match the actual entrusted waste codes to strictly prevent out-of-scope operations. Second, pay attention to cross-province transfer approval requirements; hazardous waste transferred out of Chongqing requires approval from the ecological environment department, so confirm the process cycle in advance. Third, be wary of enterprises quoting excessively low prices; hazardous waste disposal costs are transparent, and low prices are often accompanied by illegal dumping or diluted discharge risks. Fourth, regularly review the enterprises' environmental penalty records; continuous compliance during the cooperation period is more important than the initial verification.
