* Not converted to GPRA Acres, ** Priority 3 Problem Type 

Note: GPRA Acres are non-acre measures (e.g. - feet of highwalls or number of portals are converted by formula to acres. 

GPRA acres are used to measure program performance). 

All AML Programs (except AMLER and BIL) are included in this table. 

Source: Abandoned Mine Land Inventory System (AMLIS). 

1. The enhanced Abandoned Mine Land Inventory System (e-AMLIS) only provides information on the direct construction cost 

to reclaim AML features. This system was never designed to be a project management tool. E-AMLIS is the central electronic 

database for recording the national inventory of AML priorities for the AML Program. The information contained in eAMLIS is provided by States and Tribes. 

2. The AML Reclamation Accomplishments Table only reports on the direct construction costs to reclaim AML features 

expended from the AML Fund and U.S. Treasury Funds (e.g. Certified in Lieu Funds and Prior Balance Replacement Funds). 

These construction costs do not include design, engineering or administrative costs necessary for the State and Tribal AML 

programs to apply that construction cost effectively and efficiently. 

3. The two main sources of information for the AML Reclamation Program are the Financial and Business Management System 

(FBMS) and e-AMLIS. FBMS is DOI/OSMRE’s official system of record that contains comprehensive information on AML 

grant allocations and expenditures for the SMCRA Title IV AML Reclamation Program. E-AMLIS contains different 

information from FBMS and serves a different purpose. For example, e- AMLIS provides information primarily on direct 

construction cost such as estimates for reclaiming AML features once they are discovered and entered into the inventory, as 

well as completed costs when AML features are actually reclaimed in the field at which time the inventory cost is updated. 

4. GPRA Acres are non-acre measures (e.g., feet of highwall or number of portals) that are converted by formula to acres and 

used to measure program performance. 

5. The e-AMLIS inventory is not a fixed target that declines each year by the amount of reclamation accomplished. Instead, the 

inventory is dynamic and updated by States and Tribes on an ongoing basis. New AML problems are added to the inventory as 

they are identified, and cost data on existing AML problems are updated to reflect current reclamation costs. 

6. Reproducing the data in this table from the public-facing e-AMLIS webpage may be problematic. The public- facing webpage 

has limits on the type and amount of query capabilities which affect the ability of the public to replicate OSMRE published eAMLIS tables. An approved e-AMLIS account holder has more query functions than what is available to the public. 

Additionally, the OSMRE e-AMLIS Coordinator performs a rigorous quality control and quality assurance process on the 

data before it is published. This is required due to complexities in the coding system of the e-AMLIS program and retrieval of 

information that was historically entered differently (e.g. not georeferenced) and placed on a different system platform within 

the e-AMLIS program. 

7. The dataset used in the preparation of the AML Reclamation Accomplishments table was expanded to include other applicable 

e-AMLIS programs (Rural Abandoned Mine Program, Federal and State Emergency Programs, stand-alone Priority 3 

problems and, non-coal priorities). These changes account for the overall increase in each reported category in the FY 2021 

reporting of the table. Prior to FY 2019, the dataset only included certain coal programs such as Acid Mine Drainage, Coal 

Interim Site Funding, Coal Insolvent Surety Site Funding, and Pre-SMCRA Coal State/Tribe Programs, Water Supply 

Restoration Program, and Certified Program Coal Reclamation [411 (h)1 and 411 (h)2]. 

8. The AML Reclamation Accomplishments table does not include completion data for certain AML problems reclaimed under 

SMCRA prior to the 2006 Amendments, including Priority 4 and Priority 5 projects, certain non-mining related activities, and 

water supply restoration projects not linked to higher AML priorities. Priority 4 is designated for the protection, repair, 

replacement, construction, or enhancement of public facilities such as utilities, roads, recreation, and conservation facilities 

adversely affected by coal mining practices. Priority 5 is designated for the development of publicly owned land adversely 

affected by coal mining practices including land acquired as provided in Title IV for recreation and historic purposes, 

conservation, and reclamation purposes and open space benefits. Expenditures on non-mining related activities, such as 

transportation, education, or energy development were also recorded as completed costs in e-AMLIS. Water supply 

restoration relates to protecting, replacing, constructing, or enhancing facilities relating to water supply, including water 

distribution facilities and treatment plants that replace water supplies adversely affected by coal mining practices. This work 

was previously authorized by SMCRA even if there was no health, safety, or environmental priority associated with the 

work. 

9. The dataset was extracted for the 25 States and 3 Tribes that have an approved AML Reclamation Plan and the Federal 

Reclamation Program administered by OSMRE for States and Tribes that do not have approved AML program. 

10. The dataset does not include projects funded under the Abandoned Mine Land Reclamation Economic Development Pilot Program 

(i.e., AML Pilot).
