About the issue of PCB
We cannot deny possibility of a very small amount of PCB mixture About storage of transformer
We can just use thing currently using sequentially. In any of the transformer (use of PCB transformer, transformer that a very small amount of PCB mixture was confirmed) that used apparatus contains PCB, you have Manager Ministry of Economy, Trade and Industry atomic energy, NISA industry preservation supervision report by electric report rule based on “Electricity Enterprises Law” concerned, and you follow so that malfunction such as rhea oil does not occur, and please carry out check every day. In addition, it is forbidden using newly when PCB component dismantles confirmed apparatus from electric circuit.
When mixture of use of PCB transformer, very small amount PCB dismantles confirmed transformer from electric circuit and keeps, please follow as follows. In addition, it is necessary appropriate to handle that we followed as follows when we keep thing which cannot deny possibility of PCB mixture.
(“2 method of waste disposal: Clause 2 of Article 12” “the method of waste disposal enforcement regulations: 13 of Article 8, 2 Clause 3 of 2 of Article 8” “the handling of use of PCB apparatus (July, 2000 Ministry of International Trade and Industry Machinery and Information Industries Bureau electric apparatus section)”)
When we keep, we follow method of waste disposal, and I would like the handling according to the next instructions.
1) Identifiably display
We display next and distinguish from general apparatus
Indication (indication of being apparatus which or cannot deny possibility of a very small amount of PCB mixture) of being apparatus that use of PCB, a very small amount of PCB mixture were confirmed
- Amount (the number, mass, capacity)
- Indication (full name, contact information) of administrator）
- The year when we started storage
- Processing completion time limit (we show we handle by March 31, 2027)
- Reference (contact information such as maker names) of apparatus
- As for the thing which handled legal procedure of “method of waste disposal” “Electricity Enterprises Law” either, it is displayed it
2）Isolation of apparatus
We isolate so that we distinguish target apparatus from general, disposing, and insulating oil in the apparatus concerned is scattered and flows out and penetrates underground and bad smell does not display and keep. In addition, we establish partition so that non-storage person in charge and manager cannot approach apparatus.
3）Measures of rhea oil prevention
When it is to thing keeping, we receive in strong container produced with storing to container which we sealed up, materials which are hard to penetrate and prevent leak caused by corrosion from getting up.
4）Measures of fire prevention
When we keep insulating oil more than designated amount (as for the fourth kind third oil 2,000 liters), we obey technical standards such as position, structure, facilities of storage area according to the Fire Services Act.
5）Check
We check apparatus keeping regularly and try for prevention such as pollution or loss by leaks. In addition, record check result; together of apparatus keep until disposing is completed.
6）Others
When we dispose, we offer information about property, quantity of contents to trust and dispose by processing technology authorized legally.
1）In the case of transformer with apparatus that a very small amount of PCB mixture was confirmed and the possibility
When we maintain, I would like the handling such as electric insulating oil used for apparatus as follows.
- Oil which we pulled out by oil exchange work can enter container which we sealed up and keeps along Clause 1.2 mentioned above.
- We record consumption, maker, standard of oil, work day that we oiled, and oil which we supplemented newly keeps. In addition, oil to supplement newly obtains PCB fufukumishomeisho from oil maker beforehand.
- We keep tools for appliance, waste, rubber gloves which we used for extraction work of oil and polluted protection along Clause 1.2 mentioned above. In addition, we treat about case to include oil which we pulled out for investigation equally.
2）In the case of use of PCB transformer
Please do not perform oil exchange work to make nonproliferation and detoxification handling of pollution difficult.
About the law concerned
I would like the handling that followed law that is currently using and stop planned electric apparatus warns use in application (regulation) of law varying according to the situation of transformer enough and is related.
When a very small amount of PCB mixture transformer is confirmed use of PCB transformer; law ※3 ※Report according to 4 is necessary. When apparatus currently using is available continuously, but remove from electric circuit once; newly to electric circuit cannot be connected (※ 5). In addition, processing according to law (※ 1 ※ 3) is necessary at the time of the disposal. When a very small amount of PCB mixture is not confirmed, we do not receive application of law (※ 3) and can handle (0.5 mg/kg or less) as industrial waste at the time of the disposal. In addition, about apparatus told not to be able to completely deny possibility of PCB mixture, processing that is appropriate like PCB waste is necessary till it is confirmed not to contain PCB.
