Energy data Electricity consumption: 8,424,684 kWh/year Fuel consumption: 67 kl/year

*The fuel consumption values have been obtained by converting the consumptions of heavy oil, kerosene and fuel gas into the equivalent consumption of petroleum. For this purpose, the conversion coefficient for plants in Japan and overseas is the one mentioned in the regular report per "Law Concerning the Rational Use of Energy in Japan".

Waste volume data Total waste released: 260t/year Annual mean recycling ratio: 100%

*"Recycling ratio" refers to a ratio of waste (including salable waste) sold or recycled to the total amount released (other than a waste that appears not to be coped with by the efforts of Murata).

Water quality data The management level is strictly enough to meet the target level.

* N.D.: not greater than minimum limit of determination (Not Detected) *Target levels are taken from the strictest values stipulated by laws and Toyama Prefecture regulations. *Water quality data are the values measured at the final discharge point.

Air quality data The management level is strictly enough to meet the target level.

Item Unit Target level Average Max value Soot and dust g/Nm3 0.3 0.0057 0.0057 Sulfur Oxides(SOx) Nm3/h 17.5 0.03 0.03 Nitrogen Oxides(NOx) ppm 180 72 80

*Target levels are taken from the strictest values stipulated by laws and Toyama Prefecture regulations. *Air quality data are the values measured at the exhaust point.

Amount released or transported of substances to be subjected to PRTR (t/year)

Chemical compound name Amount released Amount transferred Atmosphere Public waters Soil Landfill Sewage Waste Recycling Silver and its water-soluble compounds 0.0 0.0 0.0 0.0 0.0 0.0 1.27 Toluene 2.30 0.0 0.0 0.0 0.0 0.0 9.11 Lead and its compounds 0.0 0.0 0.0 0.0 0.0 0.0 2.12

* The "amounts released or transported of substance subjected by PRTR" have been calculated in compliance with the PRTR law in Japan. The results have been rounded off to the order of 0.1 ton.
