[IMPORTANT: The table below contains two check boxes for each system component or cost category. Check the first box if your system incl udes the component/cost category listed or if the cost category (construction roads, attorney fees) was incurred during system construction/ development. Check the second box for the componen t/cost category ONLY if the total system cost you are reporting (e.g., total cost of vacuum sy stem, total cost of vacuum-pressure system, etc.) given INCLUDES the costs associated with the comp onent/cost category. If the total cost DOES NOT include the component, do not check the second box. Note that you DO NOT have to provide the cost breakdown for the system components. Yo u are providing the total cost of the system and indicating whether that cost includes the listed components/cost categories.

[IMPORTANT: The table below contains two check boxes for each system component or cost category. Check the first box if your system incl udes the component/cost category listed or if the cost category (construction roads, attorney fees) was incurred during system construction/ development. Check the second box for the componen t/cost category ONLY if the total system cost you are reporting (e.g., total cost of vacuum sy stem, total cost of vacuum-pressure system, etc.) given INCLUDES the costs associated with the comp onent/cost category. If the total cost DOES NOT include the component, do not check the second box. Note that you DO NOT have to provide the cost breakdown for the system components.
