Lignite

1. Scope and Applicability

This PCR defines foreground production of naturally occurring lignite through extraction and mine-gate release. It covers unbriquetted product, including ordinary sizing and physical separation actually performed before the gate. Exclude sub-bituminous coal, hard coal, peat, manufactured brown-coal briquettes, coke, tar, chemical conversion and customer combustion. The mass reference supports supply inventories; it does not assert equal delivered heat across grades. CPC distinguishes lignite from adjacent brown-coal products (unsd-cpc-2025). Mining environmental aspects require site-specific assessment (ifc-mining-2007).

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass	kg	Use net gate mass from cp_output; all inventory rows use per 1 kg reference flow. Preserve as-received moisture.
energy_units	mine_electricity; gate_electricity	Net calorific value	MJ	Convert metered kWh to MJ using 1 kWh = 3.6 MJ; electricity is an energy input, not product heat content.
water_units	mine_supplied_water; mine_groundwater; mine_discharge_water	Mass or volume as specified in each row	kg; m3	Keep mass and volume distinct. Convert only with recorded density and temperature; dewatering is not identical to consumptive use.
quality_basis	lignite_gate	Mass and calorific value	kg; MJ/kg	Record as-received moisture fraction w and gate calorific value; dry mass is wet mass multiplied by (1-w). Do not silently replace the wet-mass reference or use a dry-basis calorific value with wet mass.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Natural lignite seam in the ground before extraction; site development linked to the deposit
starting_condition_role	Natural resource starting condition, not a burden-free purchased product
product_classification_scope	Unbriquetted lignite; adjacent rank and manufactured-fuel categories excluded
recursive_input_rule	Purchased or transferred lignite is a separately quantified product input with a supplying dataset. Never count its prior resource extraction again or loop the model into itself.
upstream_dataset_requirement	Link fuel, electricity, supplied water, explosives, lubricants and treatment to compatible upstream datasets with geography, period and technology disclosed.
disclosure	Declare foreground gate, supplier boundaries, mine life, development and reclamation attribution, water balance and exclusions.

rule_id	applies_to	Rule	source_ids
boundary_mine	foreground	Include development attributable to extraction, overburden removal, extraction, internal haulage, dewatering, environmental controls, performed conditioning, storage, loading and attributable closure/restoration. Record capital equipment and treatment activities separately where material; justify any omission.	ifc-mining-2007
boundary_gate	downstream	End at mine-gate release; exclude off-site customer delivery and use-phase combustion. For captive mines, separate mine production from the power plant or conversion facility.
boundary_completeness	inventory	The cards define a minimum atomic inventory, not an exhaustive site bill. Add separately identified coal rejects, water-treatment chemicals, sludge, each measured water pollutant, further fuels, equipment and land-origin/destination exchanges when present. Identify all actual routes from records and document exclusions; do not substitute umbrella rows.

7. Allocation and Co-product Handling

rule_id	applies_to	Rule	source_ids
allocation_subdivide	shared_mine_operations	First isolate separately metered and directly attributable activities. Allocate shared mine operations by documented causal drivers such as material movement, pumping duty and equipment time; preserve raw totals and allocated fractions in cp_allocation.
allocation_outputs	coproducts_and_waste	Overburden, waste oil and discharged water are not coproducts merely because they leave the mine. For genuinely saleable co-extracted products, disclose the physical relationship; if no defensible subdivision or causal allocation exists, refer that dataset allocation to review. No automatic revenue share or substitution credit is prescribed.
allocation_restoration	mine_life	Attribute development and restoration from the declared mine-life plan to the corresponding recoverable output, including closure obligations. Disclose lifetime-output assumptions and sensitivities; do not burden only the final operating year or treat future reclamation as zero.
