Management of Chemical Substances
The J-POWER Group complies with applicable laws and regulations and properly uses, stores, manages, and treats chemical substances regulated by the PRTR Act, dioxins, PCB waste material (including equipment that contains trace amounts of PCB), materials that contain asbestos, and other substances that are used in power plants or are included in equipment or machinery.
PRTR Substance Release and Transfer Volumes (Fiscal 2020）
| Substance | Use | Volume handled | Volume released | Volume transferred as waste |
|---|---|---|---|---|
| 33: Asbestos | Insulation for equipment | 9.3 t/y | － | 9,320 kg/y |
| 71: Ferric chloride | Wastewater treatment agents | 5.2 t/y | － | － |
| 80: Xylene | Coating for machinery | 10.7 t/y | 3,153 kg/y | － |
| 240: Styrene | Coating for machinery | 3.0 t/y | 3,040 kg/y | － |
| 296:1、2、4- trimethylbenzene | Fuel (kerosene) | 8.8 t/y | 75 kg/y | － |
| 300: Toluene | Fuel for power generation (coal) | 16.2 t/y | 16,194 kg/y | － |
| 405: Boron compounds | Manure additives | 18.2 t/y | 0.8 kg/y | － |
- Note：Figures represent the total release and transfer volumes for all business sites handling1 ton or more per year of a Class 1 designated chemical substance or 0.5 ton or more per year of a Specific Class 1 designated chemical substance.
Scope of use (buildings and facilities) of asbestos (as of the end of March 2021)
| Items | Type of Use | Present Conditions | |
|---|---|---|---|
| Blown-in materials Containing asbestos |
Acoustic insulation, thermal insulation and fireproofing materials in facility buildings |
Appropriate measures have been taken for products containing asbestos |
|
| Asbestos- containing products |
Building materials |
Fireproofing panel, flooring for buildings, etc. |
It is considered that asbestos is contained in the building materials used before August 2006. No asbestos- containing products have been used since then. |
| Acoustic insulation |
Acoustic insulation for transformers （Transformer facility） |
Appropriate measures have been taken for products containing asbestos |
|
| Asbestos- cement pipes |
Duct wiring for underground wires （Transmission facility) |
Approx. 0.6km | |
| Thermal Insulation |
Power generation facilities （Thermal power facility） |
Remaining products containing asbestos： Approx. 21,000m3（about 20 % of total） |
|
| Sealing materials, gaskets |
Power generation facilities （Thermal power facility） |
Remaining products containing asbestos： Approx. 31,000（about half of total） |
|
| Thickeners | Electric wire for overhead transmission lines （Transmission facility) |
Electric wire corrosion prevention material Approx. 28km |
|
| Power generation facilities （Hydro power facility） |
Asphalt surface shielding membrane 3 facilities (Ootsumata-dam: Fukushima Prefecture、 Numappara- dam：Tochigi Prefecture, Hombetsu Power Station Headrace Opening Ditch: Hokkaido) |
||
| Buffers | Suspension insulations for transmission facilities |
Approx. 490,000 (Asbestos-containing products are used as buffers inside the insulations. Not used for the surface part.) |
|
- Note：Reflects the partial amendment of the Industrial Safety and Health Act Enforcement Ordinance in September 2006.(Asbestos content regulation changed from 1% to 0.1%)
