Chalk and dolomite

1. Scope and Applicability

Supply of natural chalk and uncalcined, unsintered dolomite at one declared quarry, preparation/loading or explicitly included plant-receipt gate. Cover crude and actually washed, crushed, screened, ground, powdered or physically concentrated mineral grades retaining their natural carbonate identity, and raw dolomite roughly trimmed or merely cut into rectangular blocks/slabs. Include actual selective surface or independently confirmed underground extraction, supplied-mineral preparation, dry/wet grinding and classification, conditional washing/flotation or other physical purification, dewatering, free-moisture drying, handling and packaging. Processes are actual-route conditions, not a universal chalk or dolomite recipe. Raw geological mineral lots may be homogenized only while retaining the same confirmed mineral product identity; separately identify every supplied lot and exchange. Formulated blends, coatings, chemically precipitated calcium carbonate, chemically transformed carbonate/oxide products and writing/drawing/tailors/billiard chalk are different products. Calcined/sintered/agglomerated dolomite and dolime belong to a separate product category; CPC3 separately names calcinated or agglomerated dolomite. Do not enlarge this raw-mineral boundary because the full HS dolomite heading also mentions calcined material. Phosphatic chalk, general calcareous chemical-manufacture stone, building-stone or construction aggregate reference products use their confirmed specific category; actual aggregate co-output is weighed and allocated rather than double-counted as chalk/dolomite output. Include attributable development/rehabilitation, waste, dust and water controls through the declared gate. Chemical-industry, glass, agriculture, lime/cement and refractory use are downstream of mineral supply, not mandatory foreground operations. bgs-dolomite-2006, bgs-limestone-2006, epa-crushed-stone-2004, wco-hs25-2022, ifc-construction-2007

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_basis	final_product	Mass	kg	D is the positive accepted net gate-output total in kg. Exclude packaging and cancelled internal transfers. cp_output records D; every card uses per 1 kg reference flow.
conversion	utility and material rows	Declared row property	kg; m3; MJ	Retain raw readings. Electricity: 1 kWh = 3.6 MJ. Mass/volume conversion requires measured density, temperature and applicable pressure; retain water content and active chemical fraction.
category_balance	production	Mass	kg	D is independently weighed positive accepted net as-received mineral-product kg at the stated gate, excluding packaging and rejects. Free-moisture mass fraction w has0 <= w <1; dry mineral solids = D*(1-w). For slurry measure dry solids fraction s with0 < s <=1 and dry solids = D*s; use one consistent free-water/solids basis, never both corrections. Retain D as inventory denominator and disclose dry-basis output as qualifier. Reconcile dry feed, all accepted grades/co-products, rejected fines, sludge, captured dust and stocks separately from new, recycled, evaporated and discharged water. Match actual carbonate phases and Ca/Mg/impurity assays on the same basis; reported CaO/MgO equivalents are not proof of free oxides or calcination. Loss-on-ignition includes potential carbonate decomposition and is not automatically moisture. Drying that changes carbonate identity requires product-boundary review and measured actual gases, not an assumed drying loss. Ordinary mechanical carbonate preparation produces no calcination CO2 or downstream carbonation credit; actual combustion, confirmed chemical loss or emissions are individually measured.

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Actual identified chalk/dolomite geological deposit for integrated quarrying, or supplied raw mineral with independent upstream provider for standalone preparation; cancel internal quarry/plant transfers
starting_condition_role	Resource or supplied feed; declare which
product_classification_scope	Natural chalk and uncalcined/unsintered dolomite: actual crude, physically prepared or powdered grades; raw dolomite roughly trimmed or merely cut into rectangular blocks/slabs
recursive_input_rule	Purchased same-category material carries a distinct supplier dataset; internal recycling is a balance observation, not a new external input or credit.
upstream_dataset_requirement	Link feed, electricity, fuels, chemicals, infrastructure and waste-management burdens; disclose any missing coverage.
disclosure	site/year; chalk or dolomite geological/mineral identity; actual quarry/underground/supplied-stock route; uncalcined phase and preparation; intended grade/product classification; particle size or block geometry; free moisture/slurry solids; dry-basis Ca/Mg carbonate and impurity assays with oxide-equivalent versus actual-oxide distinction; loss-on-ignition method; accepted output/stocks/returns; provider allocation; bagged or bulk; gate and explicitly included transport; water basin/discharge; waste fate and lifetime rehabilitation basis; representative UUID only compatible raw dolomite at a plant gate for glass-batch feed, not chalk or calcined dolomite

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_hierarchy	joint production	Prefer process subdivision or defensible system expansion; otherwise use demonstrated physical causality. Use economic allocation only with consistent period, price, currency and sensitivity when physical causality is unavailable. Retain the unallocated inventory.	ef-allocation-2021
allocation_product	reference and co-products	Subdivide actual mining benches, raw-block sawing, powder preparation and independently handled grades. Retain unallocated joint mineral/aggregate/other recovered-product inventories; use measured physical causality or matched economic allocation and price sensitivity if necessary. Quality rejected for industrial use may be accepted aggregate or aglime only with confirmed specification/fate, not automatically waste or free co-product. Attribute supplier and old-stock upstream burdens or justified cut-off and actual rehabilitation; allocate lifetime development/closure once over measured accepted output. No automatic avoided virgin mineral, disposal or future carbon-uptake credits.
allocation_waste	waste and recycling	Classify each output by physical state and actual fate. A sale does not automatically make a residue a co-product; internal recycling receives no avoided-product credit. Apply treatment burdens once.

Free-moisture mass fraction w has0 <= w <1; dry mineral solids = D*(1-w). For slurry measure dry solids fraction s with0 < s <=1 and dry solids = D*s; use one consistent free-water/solids basis, never both corrections. Retain D as inventory denominator and disclose dry-basis output as qualifier. Reconcile dry feed, all accepted grades/co-products, rejected fines, sludge, captured dust and stocks separately from new, recycled, evaporated and discharged water. Match actual carbonate phases and Ca/Mg/impurity assays on the same basis; reported CaO/MgO equivalents are not proof of free oxides or calcination. Loss-on-ignition includes potential carbonate decomposition and is not automatically moisture. Drying that changes carbonate identity requires product-boundary review and measured actual gases, not an assumed drying loss. Ordinary mechanical carbonate preparation produces no calcination CO2 or downstream carbonation credit; actual combustion, confirmed chemical loss or emissions are individually measured.	Matched mass, volume, composition and stock measurements	Balance residual and uncertainty

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
representativeness	dataset	Use matching production and exchange periods, actual technology, geography and supplier state. Record startup, shutdown, seasonal variation and substitutions.	collection records
identity_and_ranges	all cards	Unresolved identities and missing independent range evidence remain explicit. Do not replace measurement by a guessed industry range or by missing-as-zero.	manifest review metadata

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference	final_product	Verify 1 kg, positive D, product state, property/unit and every required qualifier. Each dataset fixes one product and route.
validate_balance	site	D is independently weighed positive accepted net as-received mineral-product kg at the stated gate, excluding packaging and rejects. Free-moisture mass fraction w has0 <= w <1; dry mineral solids = D*(1-w). For slurry measure dry solids fraction s with0 < s <=1 and dry solids = D*s; use one consistent free-water/solids basis, never both corrections. Retain D as inventory denominator and disclose dry-basis output as qualifier. Reconcile dry feed, all accepted grades/co-products, rejected fines, sludge, captured dust and stocks separately from new, recycled, evaporated and discharged water. Match actual carbonate phases and Ca/Mg/impurity assays on the same basis; reported CaO/MgO equivalents are not proof of free oxides or calcination. Loss-on-ignition includes potential carbonate decomposition and is not automatically moisture. Drying that changes carbonate identity requires product-boundary review and measured actual gases, not an assumed drying loss. Ordinary mechanical carbonate preparation produces no calcination CO2 or downstream carbonation credit; actual combustion, confirmed chemical loss or emissions are individually measured.
validate_coverage	handoff	Verify each applicable exchange, its provider or environmental compartment and final waste fate; identify skipped checks, unresolved identities, missing measurements and upstream gaps. Errors or unassessed mandatory coverage cannot be labelled complete.
