Summary of environmental and social initiatives implemented at the Ishibe Plant.

1. Environmental Initiatives

The Ishibe Plant is located near the Yasu River, which feeds Lake Biwa, the largest freshwater lake in Japan. The proximity of the plant to Lake Biwa inspired the following slogan for the plant's environment conservation initiatives: “For Lake Biwa, respect the earth and think about the future.”

Initiatives for Surrounding Residential Communities
The Ishibe Plant places a strong emphasis on initiatives that benefit the surrounding residential communities. In order to reduce noise, the plant has installed noise-proof covers around equipment and sound-deadening panels on plant buildings. In addition, the plant has made improvements to its heat treatment process to reduce odor. The plant also organizes a meeting every year to meet with local community representatives in order to gather feedback about its environmental performance.

Measures of Waste Reduction
The Ishibe Plant extensively separates waste to enable recycling of most waste such as discarded grindstones, soft and hard plastics, paper scraps, wood scraps, safety footwear, work uniforms, vinyl gloves, fluorescent tubes, beverage bottles, grinding swarf, metals scraps, waste liquids, and sludge. The plant is implementing ongoing initiatives to further improve the separation of waste and reduce the production of waste destined for incineration.
Preventing Soil Contamination
The Ishibe Plant has taken measures to prevent soil and ground water pollution from oil leaks. In fiscal year 2009, the plant removed an underground tank that was no longer needed following fuel conversion.
