The Technical Specification For Application And Issuance Of Emission Permits For Leather Industry Is About To Be Released.

At the beginning of the new year in 2017, the Ministry of environmental protection held in Beijing in January 17th the "technical specification for application and issuance of emission permits for tanning industry" (hereinafter referred to as "technical specification").

Entrusted by the Ministry of environmental protection, the China Leather Association is the chief editor of the technical specification. At the meeting, Chen Zhanguang, Secretary General of the China Leather Association, introduced the compilation of the technical specification.

The technical specification is a very important operational guidance document for the implementation of the pollutant discharge permit system, and its formulation must be scientific and reasonable.

So what are the main contents of the upcoming technical specification? What are the arrangements for the specific work schedule? What are the publicity measures for the compilation of the technical specification? What are the good guiding suggestions for the tanning enterprise to understand and grasp the requirements of the "technical specification"? What kind of impact will it bring to the future development of the leather industry? For this reason, this reporter interviewed Chen Zhanguang, the head of the technical specification compilation group and the Secretary General of the China Leather Association, asking him to conduct authoritative interpretation of the above issues for the industry.

Chen told reporters that the formulation and application of the technical specification for emission permits in tanning industry is in line with the application and issuance of emission permits in tanning industry, and provides a system basis for it. As a key work of the environmental pollution permits system of environmental tribes, the Ministry of environmental protection attaches great importance to it, and is directly coordinated by the leaders of the Ministry.

In the second half of 2016, the Ministry of environmental protection took the lead and set up a technical working group based on the China Leather Association, the China Environmental Science Research Institute, the Environmental Planning Institute of the Ministry of environmental protection, the local environmental protection department and the relevant consulting units.

In December 22, 2016, the Ministry of environmental protection held a seminar on the compilation of technical specifications, which identified the key tasks and difficulties of the project and the next implementation plan.

In January 17, 2017, the Ministry of environmental protection organized the opening of the technical specification report in Beijing.

On the same day, the leaders and relevant persons in charge of the water environmental management department and the soil environmental management department of the Ministry of environmental protection, the chief editor of the technical specification, the head of the China Leather Association, the responsible person of the China Leather Association and the responsible person of the Environmental Planning Institute of the Chinese Academy of Environmental Sciences and the Ministry of environmental protection, as well as the experts from the China Light Industry Environmental Protection Institute, the China Light Industry Cleaner Production Center, the environmental protection assessment center of the Ministry of environmental protection, the Hebei Xinji tanning District Management Committee and the Shandong Dexin Leather Co., Ltd., the representatives of Zhejiang environmental protection department, the ring academy and Jiaxing environmental protection bureau attended the meeting.

In the opening report, Cai Zhiguo, director of the water environmental management department of the Ministry of environmental protection, stressed in his speech that the formulation of the technical specification is the concrete implementation of the "implementation plan for controlling pollutant discharge permit system" and has been included in the key project of the Ministry of environmental protection in 2017, which will become an important starting point for the Ministry of environmental protection to implement environmental management.

Li Yuzhong, chairman of the China Leather Association, said at the meeting that the China Leather Association, as the editor in chief of the "technical specification", is deeply aware of the arduous task. However, it will jointly compile units, experts and pilot units, and strictly comply with the guidance and requirements of the Ministry of environmental protection, and finish the important project on time and with quality.

Secretary General Chen Zhanguang focused on the background of the project, the general situation of the industry, the necessity of formulating the technical specifications, the research methods, the organization form, the research contents, the work plan and the schedule.

The leaders and experts agreed that the technical route of the opening report was reasonable and the contents were comprehensive, which could serve as the basis for the follow-up work. At the same time, constructive suggestions and suggestions on the specific contents of the technical specification were put forward, which laid a solid foundation for the compilation of the next technical specification.

Turning to the overall progress of the "technical specification", Secretary Chen said that the progress of the work has strict time points, whether it is for the establishment units, or other participating local departments and experts, is a great test.

In accordance with the requirements of the Ministry of environmental protection, the technical specification shall complete the draft for consultation in April 2017, and form a release manuscript at the end of May. It will be completed and released at the end of June, and will be launched in July. The information reporting platform for discharge permit management, which is under the responsibility of the information center of the Ministry of environmental protection, also requires the completion of construction in April.

"Technical specification" must follow scientific and reasonable requirements. Its basic principle is "no relaxation and no strictness", mainly to ensure that in the later stage of implementation, enterprises can meet the requirements of environmental protection, and will not increase the cost burden of enterprises significantly.

Cai Zhiguo, director of the water environmental management department of the Ministry of environmental protection, stressed the opening of the technical specification.

He also pointed out that the operability of the technical specification must be strong. In order to achieve this requirement, it is very important to carry out targeted research work.

On March 7, 2017 -10, the environmental protection department of the Ministry of environmental protection organized the research group of the China Leather Association, the Chinese Academy of Environmental Sciences, the environmental protection planning department of the Ministry of environmental protection, the environmental protection assessment center, the Tianjin environmental monitoring center and the light industry Environmental Protection Research Institute. Jiang Jiaxing, who went to Zhejiang Province, conducted on-site research and technical discussions on the leather industry in Tongxiang and Haining.

Jiaxing, Zhejiang, was selected as one of the key areas for research and trial filling of the technical specification. Secretary General Chen said that the main reason is that the tanning industry in Zhejiang and Jiaxing has a high level of development.

Especially in Jiaxing, tanning industry is a local traditional and advantageous industry, and a large number of excellent tanning enterprises have emerged.

In the course of development, Jiaxing has continuously explored and improved the technological process of leather making industry.

The ability of pollution control and decontamination has been improved, and a number of low, small and scattered enterprises have been eliminated and the whole industry has been promoted.

At the same time, the sewage permit system has been promoted smoothly, and all tanning enterprises have been included in the management of the sewage permit system, which has a good foundation.

In addition, according to the public address of WeChat, "in 2015, Tongxiang, a subordinate to Jiaxing, took the opportunity of the implementation of the new environmental protection law, established and improved the pollutant discharge permit system, launched a new round of emission compensation payment and discharge permit issuance, and incorporated 4 main pollutants of chemical oxygen demand, ammonia nitrogen, sulfur dioxide and nitrogen oxides into the management scope of paid use of pollutant emission permits and pollutant discharge permits. The sewage permit system was clearly defined as a basic system for environmental management of pollution sources."

According to the data, Jiaxing has been identified as a pilot area for the sewage disposal permit system in tanning industry and has its comparative advantages.

When the reporter asked about the suggestions and opinions on the technical specifications in the course of the investigation in Jiaxing, Secretary Chen said frankly, because the contents of the "technical specification" are relatively large and the amount of information is relatively large, the enterprise needs a familiar, understood and digested process.

Therefore, at present, the opinions of enterprises are still being collected and returned to the establishment units in the process of solicitation.

Chen introduced the Hebei Xinji as another research and test area for the "technical specification". The Ministry of environmental protection plans to organize an expert group to Hebei Xinji research group in the near future.

When it comes to the main contents covered by the technical specification, Secretary Chen said that the technical specification is not only an outline of the application and issuance of emission permits for tanning industry, but also details of the permitted emission limits, feasible technologies, self monitoring management requirements, ledger records, compliance determination methods and actual discharge accounting methods.

He told reporters that in a comprehensive way,

"The main contents of the following seven aspects include: 1. The scope of application and the basic situation of the pollutant discharge unit; two, the emission outlets corresponding to the discharge ports and the permitted discharge limits; three, feasible technologies; four, self monitoring management requirements; five, the compilation of environmental management ledger records and the implementation reports; six, the compliance determination method; seven, the actual discharge accounting method.

Subsequently, Secretary General Chen made a detailed introduction and explanation to the key points and key points of the above aspects.

The scope of application clearly defines the application of the "technical specification" to guide the pollutant discharge unit of the tanning industry to fill in the application form for pollutant discharge permit and to fill in relevant information on the Internet, and also applies to instructing the issuing organ to examine and approve the licensing requirements for the pollutant discharge permit.

At the same time, it also made clear that the scope of emission permits for leather industry is all leather enterprises.

Among them, tanning enterprises including tanning process (including Retanning Process) implemented the key management of discharge permit in 2017, and other tanning enterprises implemented the discharge permit to simplify management before 2020.

Secretary General Chen explained in particular the key management and simplified management of all kinds of tanning enterprises: "in this respect, we should follow the principle of" first and then afterwards ": tanning enterprises with tanning processes (including Retanning Process) have implemented the key management of discharge permits in 2017; leather tanning enterprises starting from the leather processing in 2020 were implemented according to the" technical specification "; fur processing enterprises will separately formulate technical specifications and implement them in 2020.

In addition, in the scope of application, the pollutant scope of pollutant discharge permit management is: water pollutants and air pollutants discharged by tanning enterprises. After the introduction of the list of pollutant discharge permit classification management of fixed pollution sources, the scope of emission permits for tanning industry is regulated.

In the initial stage of reporting pollutant discharge permit, a pollutant discharge permit management information platform declaration system must be applied to fill in the basic situation of the pollutant discharge unit.

The basic situation includes the following information: basic information of pollutant discharge units, main products and production capacity, main raw and auxiliary materials, pollution discharge and pollution control facilities, production process flow chart and general layout plan of plant.

Secretary General Chen stressed that the requirements of this part should not be too cumbersome, and should be linked with follow-up work so as to avoid repeated reporting.

In terms of "permitted emission limits", including pollutant emission concentration and permitted discharge volume, the pollutant discharge standards and total volume control requirements shall be determined in principle.

Among them, special emphasis is placed on "the total concentration of chromium, ammonia nitrogen and chemical oxygen demand of tannery wastewater should be determined according to the discharge port and the permitted discharge volume."

Secretary General Chen said that calculating the permitted discharge volume of enterprises is one of the core contents of the technical specification and one of the difficulties.

The maximum permitted discharge amount of water pollutants for enterprises is determined according to the allowable discharge concentration limits of water pollutants, the unit product baseline drainage volume and the product capacity.

This specification requires more detailed rules for the calculation of the reference displacement of different processes and products, such as from raw hide to finished leather, from raw leather to wet blue, from wet blue to finished leather.

He also stressed that the final accounting standard value of the reference displacement should be guided by the general principle of "no strictness, no relaxation" by the Ministry of environmental protection, and a more scientific and reasonable numerical range should be drawn up according to the annual environmental survey.

He also reminded the vast majority of leather enterprises that the "product capacity" here refers to the "statutory capacity", rather than the actual production of "production".

The purpose of the enterprise's self monitoring management is to prove the implementation of the pollutant discharge permit, pollutant discharge node, discharge port, pollution control facilities and license limits.

When applying for a pollutant discharge permit, a tanning enterprise shall formulate its own monitoring plan according to the "technical specification" and make it clear in the application form for the pollutant discharge permit.

It should be emphasized that in the self monitoring program, the basic requirements, monitoring points, monitoring indicators, emission standards and their limits, monitoring frequency, monitoring methods and instruments, sampling methods, monitoring quality control, monitoring point map and time limit for monitoring results should be clearly defined.

In addition, enterprises can supervise the work by themselves or entrust third party monitoring organizations, and arrange full-time personnel to record, collate, analyze and monitor the monitoring data. Online monitoring and manual monitoring can be adopted.

Enterprises should be responsible for the authenticity, accuracy and completeness of the monitoring results.

In the "environmental management ledger record requirements", it is emphasized that enterprises should fill in the reporting system of discharge permit management information platform according to the requirements of the "technical specification" according to the principles of "specification, truthfulness, comprehensive and meticulous".

At the same time, enterprises are required to establish an environmental management ledger system and set up full-time personnel to record, collate, maintain and manage ledgers, and be responsible for the authenticity, accuracy and completeness of the results of ledger records.

In addition, in order to realize the purpose of carrying out the account, carrying out the certification of the license and storing it for a long time, and exporting the raw data, the functions of processing, analyzing and judging the running situation should be followed.

It is managed synchronously with two forms of paper storage and kept for more than three years.

In the "implementation report compilation standard", tannery enterprises are required to report at least one annual execution report of the permit, and the actual discharge amount of pollutants required by the permitted discharge amount shall be reported to the environmental protection department monthly or quarterly.

Compliance determination refers to the provisions of effective self monitoring data, account records and execution reports, etc. to determine whether the pollutant discharge units of pollutant discharge permit reach the permitted limit value, including the compliance level of permitted emission concentration and permitted discharge amount.

The permitted discharge amount of pollutants is up to the standard, which means that the total discharge amount of the whole plant does not exceed the permitted discharge amount of the corresponding pollutants.

At the same time, the effective daily mean value of pollutants was also defined, and three methods were classified by automatic monitoring, law enforcement monitoring and manual monitoring.

The "actual discharge accounting method" stipulates that the total amount of pollutants discharged by tannery enterprises is the sum of the actual discharge amount of the main pollutants discharged from the outlet with the permission of the discharge amount, so as to meet the annual discharge requirement of the discharge port.

At the same time, the accounting methods for the actual discharge of major pollutants in tannery enterprises are given, including the actual measurement method, the material balance algorithm, the emission coefficient method and so on. The application of these accounting methods in the accounting of waste water and exhaust gas is explained in detail.

For the key and difficult points in the "technical specification", the Secretary General Chen believes that it mainly focuses on the emission outlets and the permitted discharge limits, the conversion of the skin and the conversion of the reference displacement of different processes and products.

For the atmosphere, it is mainly due to the stench of coal fired boiler and sewage treatment system, although it is not the focus, but it should also be paid enough attention.

Finally, Secretary General Chen also stressed that during the drafting process of the "technical specification", the actual situation of leather industry was fully taken into consideration. Under the condition of ensuring effective supervision of tanning enterprises, the economic burden of them was not increased as much as possible, which is more conducive to the steady development of enterprises.
