Energy data Electricity consumption: 16,895,841 kWh/year Fuel consumption: 184 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: 296 t/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.

Item Unit Target level Average Max value Hydrogen ion concentration(pH)   5.8-8.6 7.9 7.8-8.1 Suspended Solids(SS) mg/l 120 N.D. 6 Chemical Oxygen Demand(COD) mg/l 80 3.0 5.9 Biochemical Oxygen Demand(BOD) mg/l 80 2.0 4.8 n-hexane(mineral oil) mg/l 5 N.D. 0.6 Copper mg/l 3 0.06 0.19 Zinc mg/l 2 0.20 0.43 Soluble iron mg/l 10 N.D.

*N.D. : not greater than minimum limit of determination (Not Detected) *Target levels are taken from the strictest values stipulated by laws, Ishikawa Prefecture regulations and Komatsu city 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 N.D. N.D. Nitrogen Oxides(NOx) ppm 180 73 86

*N.D.: not greater than minimum limit of determination (Not Detected) *The items lacking a target level are those being subjected to voluntary control. *Air quality data are the values measured at the exhaust point.

Amount released or transported of substances to be subjected to PRTR Any substance to be subjected to PRTR is used in an amount that necessitates registration.
