The 8(g) zone is named for the section within the Outer Continental Shelf Lands Act that designates it.
Abandoned Mine Land (AML) Fee
A fee for current day coal production that funds reclamation of mines abandoned before 1977.
This data is based on transactions that were reported to and accepted into ONRR’s financial system in a given a year. Since companies are allowed to adjust and correct data up to seven years after a transaction takes place, accounting year data can include corrections for sales that took place in previous years. This data is most useful when analyzing dollars ONRR collected and disbursed in a given year.

Federal agencies prepare an EIS if a proposed federal action is determined to affect the quality of the human environment. This is required by the National Environmental Policy Act (NEPA).
The Extractive Industries Transparency Initiative (EITI) Standard is an international standard for openness around managing revenue from natural resources. Governments disclose how much they receive from extractive companies operating in their country. These companies disclose how much they pay.

Some minerals, such as quartz crystal, are sold in small quantities in gift shops and tourist attractions. In some cases, tourists can buy admission tickets to dig for their own minerals. ONRR may collect royalties on the admission tickets, not on the weight of minerals collected. Some minerals are sold by quality rather than by weight. The unit “tickets/pounds” shows quantities measured in both tickets sold and weight sold combined.
In the U.S., one ton is 2,000 pounds. In some countries this is referred to as a short ton.

In the latter case, data is often withheld when only one company produces a specific commodity within a particular region. We withhold all location data for Native American production, revenue, and disbursements.
