Some are kept by the BLM, usually to be spent on the resource that produced them. But some minerals receipts kept by the BLM are spent on grazing. More receipts are turned over to the states or counties, and even more are dedicated to the Bureau of Reclamation. The reclamation fund probably should not be counted as a cost of resource management, but the payments to states might be. After all, these are payments in lieu of taxes, and nearly everyone considers taxes to be a cost.
Costs are only a little easier to deal with.
We counted the district budgets for each of these line items against the receipts for each resource. On top of these costs are several sorts of overhead. We added these to the district costs proportionate to the size of the district budgets. For example, if the Boise District spent a quarter of district forestry funds in Idaho, then we added a quarter of the state office's forest management funds to Boise's costs. The minerals costs also include an appropriate share of the Minerals Management Service's costs of collecting receipts for minerals leasing on BLM lands.
