      The "Administrative Measures for the Prevention and Control of Water Pollution by Inland Ships Under 400 Gross Tonnage" (hereinafter referred to as the "Administrative Measures") issued by the Ministry of Transport will be implemented on October 1.
    The "Administrative Measures" clarify water pollutants from inland vessels under 400 gross tonnage.
    Prevention and control are mainly carried out in accordance with the principle of "storage on board, receiving and disposal on shore", with special emphasis on the implementation of new classification requirements for inland river vessel garbage to connect it with urban garbage classification.

      “In the past, only ships of more than 400 gross tonnage had such a requirement.
    ” Xu Chen, surveyor of the fifth detachment of the Nanjing Municipal Law Enforcement Bureau, Jiangsu Province, said on September 22.
    The "Management Measures" made up for the existing national standards for the emission control of such ships.
    Missing requirements.

      The phenomenon of surreptitious discharge of water pollutants from ships is common.

      In the mode of transportation, inland waterway navigation has the advantages of large capacity, small area, low energy consumption, and low pollution.
    Since the reform and opening up, my country has focused on promoting the construction and development of inland navigation with the Yangtze River, Pearl River, and Huai River as the main body.

      "As of the end of 2019, the navigable mileage of China's inland waterways reached 127,000 kilometers, ranking first in the world.
    Among them, the planned 19,000 kilometers of high-level inland waterways have reached about 16,000 kilometers to meet the planning standards, which initially constitutes a connection between the east, middle and west of China.
    The inland waterway that connects rivers and seas, connects trunks and branches, and partially forms a network.
    ” said Sun Wenjian, a spokesperson for the Ministry of Transport.
    Among them, more than 60% of inland watercraft are small ships of less than 400 gross tonnage, distributed in the Yangtze River, Pearl River and other water systems and Beijing-Hangzhou.
    Inland waters along the canal.

      According to reports, relevant law enforcement inspections found that the actual operating rate of sewage treatment facilities on ships is low, the standards for the control of domestic sewage discharge from ships under 400 tonnage are lacking, and supervision is blank.
    In 2018, in the middle and upper reaches of the Yangtze River alone, there were 211 cases of not equipped with corresponding anti-pollution equipment and 117 cases of illegal sewage discharge were notified.
    Among them, the black oily sewage from the docked ship "Nahai" at the China Resources Power Plant Wharf in Changshu City, Jiangsu Province was discharged directly into the river from the deck outlet, which was shocking.

      “Previously, when dealing with pollutants such as ship’s domestic garbage and domestic sewage, the regulatory agencies mostly adopted a market-oriented operation method, and the registered receiving units provided paid services.
    ” said Wang Shiming, deputy director of the Jiangsu Maritime Safety Administration, “but only charging does not do anything.
    Circumstances such as arbitrarily charged fees and charges have occurred from time to time, which has caused many inland vessels to discard garbage and discharge domestic sewage at will.

      On August 23, 2019, at the special inquiry meeting of the Enforcement Inspection Team of the Standing Committee of the National People's Congress on the inspection of the implementation of the Water Pollution Prevention and Control Law, Luo Baoming, a member of the Standing Committee of the National People's Congress, said that the relevant inland river environmental protection inspection found that the port and terminal can receive, dispose, and transfer capacity.
    Obviously inadequate, and even missing, the phenomenon of surreptitious discharge of water pollutants from ships is more common.

      In more than three months before the end of 2020, the "Administrative Measures" was promulgated.
    The relevant person in charge of the Ministry of Transport said that this is not only one of the specific measures to do a good job in the protection of the Yangtze River, but also the implementation of the special inquiry meeting of the Enforcement Inspection Team of the Standing Committee of the National People's Congress on the inspection of the implementation of the Water Pollution Prevention and Control Law last year.
    committed to.

      Implementation of the principles of on-board storage, delivery and disposal.

      The “Administrative Measures” include 7 parts including general rules, general regulations, domestic sewage pollution prevention, ship garbage pollution prevention, prevention and treatment of oily sewage pollution in machinery spaces, prevention and control of tank washing water pollution, and supervision and management.
    A total of 27 items.

      The "Administrative Measures" specifically provides opinions on the disposal of garbage from ships in inland waterways, that is, the principle of "storage on board and receiving and disposal on board" shall be implemented for the prevention and control of water pollution from ships.
    "Tighten the'head' that discharges sewage to the Yangtze River thoroughly.
    " Sun Wenjian said.

      The "Administrative Measures" specifically emphasizes that ships must not discharge water pollutants into inland waters in violation of laws, administrative regulations, standards, norms and the provisions of the Ministry of Transport.
    Ship water pollutants that do not meet the discharge regulations shall be handed over to reception facilities for treatment.
    Garbage and domestic sewage from ships in the epidemic area can only be received and processed after being quarantined by the quarantine department.

      The "Administrative Measures" also put forward three prohibitions, namely, prohibiting ships from discharging oily sewage containing cargo oil residues, residual oil (oil sludge), sewage containing toxic liquid substances, and ship garbage into inland waters; prohibiting ships from protecting drinking water sources Districts, the Beijing-Hangzhou Canal, the Lijiang River and other waters where the discharge of domestic sewage is prohibited; ships are prohibited from discharging oily sewage from machinery spaces in the Three Gorges Reservoir area, Beijing-Hangzhou Canal, Lijiang River and other waters where oily sewage from machinery spaces are prohibited.

      At the same time, the "Administrative Measures" also stipulate that ports, wharves, and loading and unloading stations should be equipped with ship water pollutant receiving facilities that meet the receiving needs of arriving ships, and must not refuse to receive garbage, domestic sewage, and oily sewage delivered by ships calling at the port.
    Encourage ports, docks, and loading and unloading stations to receive domestic sewage and garbage from ships for free.

      "I used to want to send domestic sewage ashore, but I don't know where to send it.
    " said Li Dehao, the captain of the "Suhuahang 2288" in Jiangsu Province.
    With the rapid follow-up of supporting facilities, the sewage has a destination.

      At the beginning of 2019, the nation's first domestic sewage centralized landing treatment station-the Nanjing Port Xinshengwei Ship Sanitary Sewage Receiving, Transfer, and Treatment System was officially put into operation.
    Di Feng, deputy general manager of Nanjing Port Group, said that relying on the treatment station, Nanjing Port has put 4 ships into the anchorage and other areas to collect domestic sewage for free and transfer to the treatment station for treatment.

      According to Sun Wenjian, since the beginning of this year, 12,608 receiving facilities have been built in the provinces and cities along the Yangtze River, 11 provinces and cities have achieved full coverage, and most ports have implemented the policy of receiving free ship garbage.
    The construction of the barge or the main project of the chemical tank washing station on the main line of the Yangtze River has started and is progressing steadily.
    Among them, two new tank washing stations in Nantong, Jiangsu have started trial operation ahead of schedule.

      Promote the construction and transformation of sewage collection or treatment equipment.

      In terms of the prevention and control of domestic sewage pollution and oily sewage pollution of machinery premises, the "Administrative Measures" stipulates that ships that produce domestic sewage should be equipped with treatment devices or storage facilities to prevent domestic sewage from polluting waters.
    Ships that produce oily sewage in machinery spaces shall be equipped with treatment devices, storage compartments (cabins) or containers to prevent oily sewage in machinery spaces from polluting the waters.

      Existing ships that are not equipped with anti-pollution facilities for domestic sewage and oily sewage in machinery spaces, and existing ships that have installed sewage treatment devices but whose discharge after treatment cannot meet the requirements of the "Ship Water Pollutant Discharge Control Standard" are required to comply with the "Inland River" The Technical Regulations for Ship Statutory Inspection (2019) have completed the transformation, and ships are encouraged to carry out transformations in accordance with the principle of “storage on board, receiving and disposal on board”.

      In fact, the Ministry of Transport has been advancing the construction and transformation of marine sewage collection or treatment devices.

      As early as 2019, the Jiangsu Maritime Safety Administration proposed to establish a "four free" management mechanism of "free traffic, free anchoring, free reception of domestic waste, and free reception of domestic sewage" for inland water vessel pollutants.

      From January to July this year, 13 provinces and cities have rebuilt a total of 21,920 ships.
    10 provinces and cities have introduced subsidy policies for the renovation of domestic sewage facilities for ships of 100 to 400 tons.
    Jiangxi Province and Hunan Province have completed the task of preventing pollution from ships’ domestic sewage in advance.

      The reporter is concerned that in order to improve the operability of "storage on board, receiving and disposal on board," the "Administrative Measures" imposes new classification requirements on inland waterway vessel garbage to connect it with urban garbage classification.

      The "Administrative Measures" propose that ships producing garbage should be equipped with collection and storage or pretreatment facilities to prevent garbage from polluting waters, and all garbage should be delivered to receiving facilities.
    Ship garbage should be collected and stored separately, and it is recommended to meet the four classification requirements of kitchen waste, recyclable garbage, hazardous garbage, and other garbage.
    In addition, the "Administrative Measures" also stipulate that port operators and ships establish a ship-to-shore transfer and joint inspection system for ship water pollutants.

      How to deal with garbage treatment before the completion of the renovation of domestic sewage anti-pollution facilities and equipment and oily sewage anti-pollution facilities and equipment of machinery spaces? For this reason, the "Administrative Measures" also stipulates that "temporary alternative measures should be taken to collect domestic sewage and oily sewage from machinery spaces, and direct discharge is strictly prohibited.
