<h1 class="pgc-h-arrow-right" data-track="6" >1. Reply on whether municipal separate incineration of fly ash can be hygienically landfilled</h1>
2019-06-11
Letter:
According to the "Domestic Waste Incineration Pollution Control Standard" (GB18485-2014), "1 Scope of application: ... The pollution control of the sludge generated by domestic sewage treatment facilities and the special incinerator for general industrial solid waste is carried out with reference to this standard", "8.6... Domestic waste incineration fly ash should be managed according to hazardous waste, such as entering the domestic waste landfill disposal, should meet the requirements of GB16889...", can it be understood that the fly ash generated by the sludge generated by domestic sewage treatment facilities and the special incinerator of general industrial solid waste should be managed in accordance with hazardous waste, after meeting the requirements of GB16889 , can enter the domestic waste landfill disposal. The above understanding and the "Domestic Waste Landfill Pollution Control Standards" (GB16889-2008), "6.8 wastes below shall not be disposed of in landfills (1) hazardous wastes other than domestic waste incineration fly ash in accordance with Article 6.3", and "6.3 domestic waste incineration fly ash and medical waste incineration residues (including fly ash and bottom slag) can enter the domestic waste landfill for disposal after treatment meet the following conditions".
Reply:
According to the National Hazardous Waste Directory (2016), HW18 (incineration disposal residue) includes domestic waste incineration fly ash, bottom slag, fly ash and wastewater treatment sludge generated by hazardous waste incineration, pyrolysis and other disposal processes (except for the bottom slag generated by medical waste incineration disposal), non-glassy substances produced by hazardous waste plasma, high temperature melting and other disposal processes, and waste activated carbon generated by waste gas treatment during the incineration of fly ash and solid waste. The "sludge produced by domestic sewage treatment facilities and fly ash from special incinerators for general industrial solid waste" mentioned in the letter does not belong to HW18 (incineration disposal residue). According to Article 8 of the National Hazardous Waste Directory (2016), "For solid wastes that are not clear whether they have hazardous characteristics, they shall be identified in accordance with the hazardous waste identification standards and identification methods stipulated by the state", it is necessary to identify the hazardous characteristics of the sludge generated by domestic sewage treatment facilities and the fly ash generated by the special incinerator of general industrial solid waste. After being identified as having hazardous characteristics, it belongs to a hazardous waste, and the category of waste to which it belongs shall be determined according to its main components and hazardous characteristics, and classified and managed according to the code "900-000-xx" (xx is the hazardous waste category code). Those identified as not having hazardous characteristics are not hazardous wastes.

In the Catalogue of Classified Management of Environmental Impact Assessment of Construction Projects (Decree No. 44 of the Ministry of Environmental Protection, implemented from September 1, 2017), the "34. Environmental Governance Industry" clarifies the environmental impact assessment categories such as "desulfurization, denitrification, dust removal, hazardous waste (including medical waste) utilization and disposal, general industrial solid waste (including sludge) disposal and comprehensive utilization, and pollution site remediation and restoration", but for construction projects that only increase or change environmental protection measures and reduce the emission of major pollutants compared with existing projects, The list does not specify its EIA categories. In addition, according to the Environmental Affairs Office [2015] No. 52, 'a major change occurs in one or more of the five factors of the nature, scale, location, production process and environmental protection measures of a construction project, and may lead to significant changes in the environmental impact (especially the aggravation of adverse environmental impacts), it is defined as a major change'. In summary, it is recommended to clarify the EIA categories of VOCs and other pollutant environmental remediation projects (other projects remain unchanged)? Is a change in environmental protection measures that weakens the adverse environmental impact a significant change?
You have received a letter from the "Minister's Mailbox" on our website "Suggestions on Clarifying the Environmental Impact Assessment Categories of Environmental Engineering such as VOCS". After study, the response is as follows:
I. For the question of "environmental impact assessment categories of VOCS and other pollutant environmental remediation projects", the environmental impact assessment category shall be determined in accordance with the "Catalogue of Classified Management of Environmental Impact Assessment of Construction Projects", comprehensively considering the scale of project construction, the complexity of the process, and the size of environmental risks.
Second, the question of "whether changes in environmental protection measures weaken the adverse environmental impact and are major changes". The Notice on Printing and Distributing the List of Major Changes in Construction Projects in Some Industries under the Management of Environmental Impact Assessment (Environmental Affairs Office [2015] No. 52, hereinafter referred to as the "Notice") clearly stipulates that "if one or more of the five factors of the nature, scale, location, production process and environmental protection measures of the construction project has a major change, and may lead to significant changes in the environmental impact (especially the aggravation of adverse environmental impacts), it is defined as a major change", and gives a list of major changes in nine industry construction projects such as hydropower. In the process of operation, it should be combined with the actual situation of the project and in accordance with the relevant requirements of the Notice to define whether the project change is a major change.
Thank you for your concern and support for the cause of environmental protection.

Q: Hello Director: The waste fluorinated wastewater treatment sludge generated by our company is defined as hazardous waste in the environmental impact assessment report, but in 2016, when the state revised the hazardous waste list, the fluorinated wastewater treatment sludge was deleted, because our company generated a small amount, when preparing for transfer, it was found that the only administrative license that can dispose of fluorine wastewater treatment sludge in Ningxia has been cancelled, and the preparation of inter-provincial transfer (Shaanxi Province) consultation found that they did not accept, so it was impossible to handle inter-provincial transfer. The EPA is requested to confirm whether it is removed from the definition of hazardous wastes in accordance with the new national hazardous waste list and disposed of in accordance with general wastes. Or introduce a unit that can dispose of such waste for our company to dispose of.
A: Hello, please consult the Solid Hazardous Waste Chemicals Administration at 0951-5160715.

7. Q: The overall proportion of the photovoltaic industry in our province is leading with other provinces, and its pollutants include waste gas, wastewater, and waste residue, of which wastewater mainly contains fluoride, and the existing treatment processes of photovoltaic enterprises are treated with calcium chloride or quicklime, and the qualitative calcium fluoride sludge produced often becomes a major threshold for the environmental impact assessment of photovoltaic enterprises. After the enterprise pays a large investment, the third party is invited to conduct a qualitative appraisal, which is generally not a hazardous waste after treatment. Under the current hazardous waste identification process and appraisal system, the cycle of hazardous waste appraisal is generally longer. The main reasons are the large number of samples required for identification, the long sampling and detection time, and the general cycle is about three months. The identification cycle is too long, causing the enterprise to lag behind the management of solid waste, and the enterprise will be subject to the local competent departments in terms of storage and treatment, and in the process of identification, there will be unreasonable disposal of the identification object, which may cause harm to the environment. At the same time, the identification of identification conclusions lacks flexibility, and the actual operation process of the enterprise may undergo changes in some processes or raw materials and other aspects due to various reasons such as technology, market, and policy. Enterprises are directly required to re-carry out hazardous waste identification, which is a heavy burden and unscientific. At the same time, the hazardous waste identification work involves many departments, and the departments have encountered certain difficulties in the process of hazardous waste identification due to the lack of effective communication before. Environmental impact assessment approval, completion acceptance and hazardous waste identification are the responsibility of different environmental protection authorities, how to solve the above contradictions between various departments, how to make a clear conclusion on the intervention time of hazardous waste identification work, is an urgent need to solve the problem. Please ask the Environmental Protection Agency to carry out detailed planning for the identification of fluorine-containing sludge in the photovoltaic industry to reduce the burden on enterprises, thank you!
A: Hello! Your inquiry about the "Characterization of Fluorinated Sludge in Sewage Treatment Processes in the Photovoltaic Industry" has been received. After careful study, the reply is as follows: First, in recent years, the state has issued the "General Principles of Solid Waste Identification Standards", "Hazardous Waste Identification Standards" and "Hazardous Waste Identification Technical Specifications" and other standards and normative documents, which clarify the relevant technical requirements for the determination of solid waste attributes and the identification of hazardous characteristics, including the number of samples, sample collection methods, testing and analysis indicators, etc. 2. On October 1, 2017, the former Ministry of Environmental Protection issued the "Guidelines for Environmental Impact Assessment of Hazardous Wastes in Construction Projects" to be implemented. Taking into account the actual needs of enterprises and the reality of environmental management, in 2018, our office issued the "Notice on the Implementation of the Guidelines for the Environmental Impact Assessment of Hazardous Wastes in Construction Projects" (Su Huan Ban [2018] No. 18), which effectively links the conclusions of hazardous waste identification with the environmental management requirements of construction projects, and clarifies the intervention time of hazardous waste identification and how to connect with environmental impact assessment and acceptance. The notice requires that "for solid wastes not included in the National Hazardous Waste Directory (2016 edition), the attributes cannot be determined after analyzing the process flow, production links, main components and harmful components, and the identification and confirmation of hazardous characteristics should be carried out in the environmental impact assessment documents, and detailed hazardous waste characteristics identification scheme suggestions should be given in the environmental impact assessment documents according to the requirements of relevant national standards and technical specifications, and the detection indicators and sampling quantity and frequency should be clarified", and "the identification of hazardous waste characteristics should be required in the environmental impact assessment documents." After the completion of the project construction, the construction unit should carry out the identification of waste attributes in a timely manner, and include the identification conclusions and the implementation of environmental management requirements into the scope and report of the acceptance of the environmental protection facilities supporting the construction. The construction unit shall bear the main responsibility for the identification conclusion, and if it entrusts the identification, the entrusted institution shall bear the corresponding legal responsibility for the identification conclusion." 3. The General Principles of Hazardous Waste Identification Standards stipulate that "solid wastes that are not listed in the National Hazardous Waste Directory or cannot be identified according to hazardous waste identification standards, but may cause harmful effects on human health or the ecological environment, shall be identified by experts organized by the competent administrative department of environmental protection under the State Council". According to the requirements of national laws and regulations and standards, our office does not have the authority to formulate relevant plans for the appraisal work. In 2017, the former Ministry of Environmental Protection publicly solicited relevant suggestions on the "Hazardous Waste Exclusion Management List (Draft for Comments)", in which calcium fluoride sludge was included in the "Hazardous Waste Exclusion Management List (Draft for Comment)". At present, the "Hazardous Waste Elimination Management List" has not been officially released, and the hazardous characteristics and subsequent disposal of calcium fluoride sludge should be implemented according to the actual situation of each enterprise and in accordance with the environmental management requirements of construction projects. Thank you for your concern and support for Jiangsu Environmental Protection!

9. Q: My unit is the production of tire cord fabrics and industrial fabrics. In 2019, our company transformed and upgraded the waste gas treatment equipment, changed from the original washing treatment equipment to RTO equipment, and compiled the "Environmental Impact Report Form for Environmental Protection Facilities Upgrading Comprehensive Technical Transformation Project". The upgrading project involved drying and dewatering the wastewater sludge in this section. In the process of project approval, our company and the local environmental protection approval department have objections to the declaration of this part: the local environmental protection approval department: the environmental impact assessment classification management directory of construction projects (2018) / 34, environmental governance industry / 100 / hazardous waste (including medical waste) disposal and comprehensive utilization / utilization and disposal, the preparation of environmental impact assessment report. Our company believes that: 1) in the company's technical transformation project, the sludge drying project, as a link in the wastewater treatment process, only drys and dehydrates the sludge, and collects the volatile gases in the drying process to the RTO facility for treatment, without involving major environmental impacts. 2) The unit is classified as a textile category, this sludge re-drying should be used as a link in the wastewater treatment process, and does not belong to the "hair washing, dyeing and finishing, degumming section, nor does it involve the production of silk reeling wastewater, refining wastewater items". No additional reports are required. The above is our personal understanding, and I hope that the leadership can give guidance, thank you!
A: It is recommended to prepare an environmental impact report form in accordance with the "Catalogue of Classified Management of Environmental Impact Assessment of Construction Projects" in "33, Water Production and Supply Industry, 97 Industrial Wastewater Treatment".

10. Q: Consultation on the pilot collection objects in document [2019] No. 390 of the Suhuan Office: In the circular [2019] No. 390 of the SuzhouHuan Office, the pilot collection objects include "hazardous waste generated by enterprises and institutions with an annual output of less than 10 tons in the districted city where the pilot unit is located". Does 10 tons here refer to enterprises and institutions with an annual total product of less than 10 tons or can a single hazardous waste type be less than 10 tons? Because in practice, some enterprises produce more types of waste, a total of more than 10 tons, but a single type of hazardous waste is less than 10 tons, and in the disposal process, there is no disposal unit that can collect and dispose of all at once, like this case, can the pilot unit collect? In some waste-producing units, a single type of hazardous waste produces more than 10 tons (such as hazardous waste sludge), and other hazardous wastes are small, and the disposal units that collect hazardous waste sludge are unwilling or unqualified to recycle other small amounts of hazardous waste, can the pilot units also collect them? After all, the issuance of the document is to solve the current situation of the difficult disposal of hazardous waste in enterprises, if the pilot units like the above two situations cannot be collected, then the hazardous waste disposal of such enterprises still needs to find several units to dispose of, the cost of hazardous waste disposal is still very high, and the problem has still not been solved.
A: The pilot collection objects in Document No. 390 of the SuHuan Office (2019) include "hazardous wastes generated by enterprises and institutions with an annual production volume of less than 10 tons in the districted city where the pilot unit is located", of which the annual output of less than 10 tons refers to the total annual production of hazardous wastes of less than 10 tons. According to Document No. 390 of the SuHuan Office (2019), the objects of the pilot collection include "hazardous waste generated by enterprises and institutions with an annual production volume of less than 10 tons in the districted city where the pilot unit is located; laboratory waste (except medical waste) generated by scientific research institutes, colleges and universities, various testing institutions, etc.; hazardous waste generated by motor vehicle maintenance institutions, gas stations, etc.". Within the scope of the pilot area, the pilot collection unit will collect and store the hazardous waste generated by the above-mentioned pilot collection objects.

9. Q: The enterprise is engaged in the production of sintered porous bricks, the main raw materials include river silt, medium soil (domestic sewage treatment plant sludge after anaerobic fermentation treatment products) and water plant sludge, all belong to the general industrial solid waste. Because the three raw materials contain very low amounts of mercury, chromium, lead, arsenic and other heavy metal elements, the sintered flue gas emission pollutants generated in the brick making process contain the above heavy metals and their oxides. According to the Interim Measures for the Review and Management of total discharge targets of major pollutants in construction projects (Huanfa [2014] No. 197), it is not clear whether the total discharge target of heavy metal pollutants is required for general solid waste utilization and disposal projects; according to the Opinions of the Ministry of Ecology and Environment on Strengthening the Prevention and Control of Pollution in Heavy Metal Industries (Huan Soil [2018] No. 22), the total discharge target of heavy metal pollutants is not required for general solid waste utilization and disposal projects. Whether brick-making projects using general solid waste such as river silt, dielectric soil and waterworks sludge need to apply for the total discharge target of heavy metal pollutants in the exhaust gas?
A: The Opinions of the Ministry of Ecology and Environment on Strengthening the Prevention and Control of Pollution in Heavy Metal-related Industries (Ring Soil [2018] No. 22) stipulates: "New, reform and expansion of key heavy metal-related industries construction projects must follow the principle of "reduction and replacement" or "equal replacement" of key heavy metal pollutant emissions, and there should be a clear and specific source of total heavy metal pollutant emissions in the administrative region of this province (district, city). Among them, the key industries involving heavy metals include heavy non-ferrous metal mining and dressing industry, heavy non-ferrous metal smelting industry, lead-acid battery manufacturing industry, leather and its products manufacturing industry, chemical raw materials and chemical products manufacturing industry and electroplating industry.

10. Q: Whether the printing and dyeing wastewater sludge is the same as the domestic sewage sludge: Our company has a batch of printing and dyeing wastewater sludge, which belongs to the general industrial solid waste, and it is necessary to find a unit with relevant comprehensive utilization or disposal capacity in the near future. Now there is a unit in its environmental impact assessment clearly has the comprehensive utilization capacity of domestic sewage treatment sludge, according to the "General Solid Waste Classification and Code" (GB/T39193-2020), printing and dyeing sludge and domestic sewage plant sludge belong to the "organic wastewater sludge" (code 62). Can it be understood that this unit that allows the comprehensive utilization of domestic sewage plant sludge can actually make comprehensive use of our printing and dyeing wastewater sludge (organic wastewater sludge).
A: Hello! According to the "General Solid Waste Classification and Code" (GB/T39193-2020), although the printing and dyeing sludge and the sludge of domestic sewage plants belong to the same 62 categories, they belong to different sub-classifications under the 62 categories. In addition, due to the difference in process flow, domestic sludge and printing and dyeing sludge have different components that have a relevant impact on the environment, and units with domestic sludge processing capacity do not necessarily have printing and dyeing sludge treatment capabilities. Therefore, according to the requirements of the Solid Waste Law, your unit entrusts a unit with corresponding subject qualifications and technical capabilities to use or dispose of printing and dyeing sludge.
