### The information provided herein is the most responsive financial information available given the fact that our accounting systems do not track costs in the manner requested by the Environmental Protection Agency (“EPA”). If EPA determines that an unacceptable risk exists, it is recognized that EPA may at some point propose a specific technology or process modification to reduce that risk which will require a cost impact assessment. Providing a projected cost impact of a specific proposal is more feasible because it is a specific and discrete proposal, not an historical incident that has never been included in our accounting systems cost calculations. Therefore, we request that should such a specific proposal be brought forth by the Agency, that we be given an opportunity to provide EPA with relevant cost information. This information would be more responsive and useful with respect to any specific regulatory proposal and could include items such as installation costs, total capital costs, method of financing APCD, retrofit installation, and other costs that would be directly relevant to the regulatory issues that would arise with any new proposal.

foam, foam boards, cotton treated to resist fires, and sheep wool treated to resist fires. W ool fiberglass insulation is preferred over these alternative insulation m aterials because it is easily
