3.1 What level of capital expenditure and product conversion costs would you anticipate to

make at higher standard levels? Please describe what they are and provide your best

estimate of their respective magnitudes.

3.2 How would the imposition of new energy conservation standards affect employment,

capacity utilization and manufacturing assets at your domestic production facilities? Would

a new standard result in stranded capital assets? Would any facilities be closed or

downsized? Added or upgraded?

other features?

6 Cumulative Regulatory Burden

6.1 Are there recent or impending regulations on your specific product or other products that

impose a cumulative burden on the industry?
