Reclamation Surety Glossary — Mining, Oil & Gas, BLM Terminology

AOC — Approximate Original Contour: The post-mining land surface configuration that approximates the pre-mining contour, as defined under SMCRA. AOC is the principal performance standard for surface-mined coal lands.
Bond Adequacy Review: A periodic recalculation by the obligee of the penal sum required to reclaim a permitted area, based on current contractor rates and the current state of disturbance.
Bond Form: The specific written instrument prescribed by an obligee on which a surety bond must be executed. State and federal bond forms differ — substituting one form for another invalidates the bond.
Bond Key: A published cost calculation methodology used by a state or federal regulator to determine the penal sum required for a particular reclamation obligation.
BLM — Bureau of Land Management: The federal agency within the U.S. Department of the Interior that administers federal mineral leases, locatable mining claims, and surface management of public lands.
Cancellation: Termination of the surety's prospective obligation under a bond. Most reclamation bonds are non-cancelable or cancelable only on long notice with the obligee's consent.
CERCLA: The Comprehensive Environmental Response, Compensation, and Liability Act of 1980, the federal statute governing the cleanup of hazardous substance releases. CERCLA financial assurance obligations are frequently secured by surety bond.
Collateral: Cash, marketable securities, irrevocable letters of credit, or other property pledged by the principal to the surety as security for the principal's indemnity obligation.
Continuous Bond: A bond that remains in force from its effective date until released, without a fixed expiration. The surety's obligation is renewed each year by payment of the annual premium.
Cost Estimate: The agency's calculation of the third-party cost to complete the reclamation plan if the operator defaults. The bond penal sum is set to or above this estimate.
Default: Failure of the principal to perform the bonded obligation in accordance with the underlying statute, regulation, permit, or order.
Directive 882: The Office of Surface Mining Reclamation and Enforcement directive establishing bond-adequacy methodology for the federal coal program and widely adopted by state programs.
Financial Assurance: Collective term for the several instruments — surety bond, letter of credit, cash, trust fund, or self-bond — that a regulator accepts as security for reclamation.
Forfeiture: The legal process by which an obligee declares a default and proceeds against the bond to recover the penal sum.
Indemnity Agreement: The written contract under which the principal (and, typically, individual owners) agree to reimburse the surety for any loss the surety pays under the bond.
Locatable Minerals: Hardrock minerals — gold, silver, copper, and others — open to location under the Mining Law of 1872, distinct from leasable minerals (oil and gas, coal, phosphate) and salable minerals (sand, gravel, common varieties).
MSHA: The Mine Safety and Health Administration. MSHA regulates worker safety; it does not require reclamation bonds, though MSHA compliance history is reviewed in reclamation underwriting.
NOV — Notice of Violation: A written notice from an obligee identifying a specific deviation from permit conditions, statute, or regulation. NOVs are abated by corrective action and a final abatement date.
Obligee: The party named in the bond as entitled to make a claim — the state or federal regulator, or in remediation matters, the court.
OSMRE: The Office of Surface Mining Reclamation and Enforcement, the federal agency within the Department of the Interior that administers SMCRA.
P&A — Plugging and Abandonment: Permanent closure of an oil or gas well in accordance with state regulation, typically including cement plugs at multiple depths and surface restoration.
Penal Sum: The maximum dollar amount the surety can be required to pay under the bond. Distinct from the agency's underlying cost estimate, though typically set equal to it.
Performance Bond: A surety bond securing performance of an obligation, as distinct from a payment bond. Reclamation bonds are performance bonds.
Phase I / II / III Release: Three-stage release of a SMCRA coal reclamation bond — after backfilling and drainage controls, after revegetation establishes, and after the full liability period demonstrates vegetative success.
Plan of Operations: A written plan submitted to BLM under 43 CFR 3809 for surface disturbance above the Notice-level threshold on locatable mineral claims. Requires a 3809 surface management bond.
Principal: The operator named in the bond — the party whose performance is guaranteed.
RCRA: The Resource Conservation and Recovery Act, the federal statute governing solid and hazardous waste management. Hazardous waste facilities require financial assurance for closure and post-closure care, frequently in the form of a surety bond.
Reclamation Plan: The written, agency-approved plan describing how an operator will return disturbed land to a post-disturbance condition. The plan is the basis for the bond calculation.
Rider: A written amendment to an existing bond, executed on the obligee's prescribed form, to modify the penal sum, the operator name, or other bond terms.
Self-Bonding: Permitted, in limited programs, in lieu of a surety bond when the operator meets strict net-worth, debt-coverage, and other financial tests.
SMCRA: The Surface Mining Control and Reclamation Act of 1977, the federal statute governing coal mining reclamation.
Surety: The surety company that issues the bond and stands behind the principal's performance.
Surface Management Bond: A BLM bond filed under 43 CFR 3809 for locatable mineral operations on public lands, securing reclamation of surface disturbance.
