Mining After the EIA Certificate: Conditions the Commission Enforces

This page is the mining environmental conditions operating file: what the mineral right, and the desk administering it, demand of a mine once the certificate is in hand. It is not an assessment manual, nor the periodic audit duty under the Environmental Management Act Cap. 191.

• Getting the certificate itself: when an EIA is required
• The other annual plan: mining local content and procurement
• Trading rather than digging: mining dealership licences
• Conditions differ by commodity: Tanzania mining by mineral

As at 14 September 2026. Confirm live licence conditions and bond practice with the Mining Commission at tumemadini.go.tz; this file rests on Cap. 123 and its regulations, Cap. 191, and the water, chemicals, radiation and land instruments below.

Who signs the certificate, and who enforces it afterwards

Two mandates are routinely confused. Under Cap. 191 the National Environment Management Council registers a project, screens it, reviews the impact statement and recommends; the Minister responsible for environment, in the Vice President’s Office, signs. What binds afterwards is the schedule of conditions on that certificate, not the consultant’s report behind it.

Once a mining licence or special mining licence is granted, a second authority takes over. The Mining Commission administers mineral rights under Cap. 123, and works through zonal offices and a Resident Mines Officer at each project. The remedies differ: the environment desk serves compliance and restoration orders, while the Commission can withdraw the right itself.

Both subjects are non-Union, and Cap. 123 and Cap. 191 are Mainland statutes. Zanzibar licenses minerals through its own ministry and controls impact through the Zanzibar Environmental Management Authority under the island’s 2015 statute; companies register at BPRA and non-Union taxes go to ZRA.

Reserved ground: a primary mining licence is a citizen’s instrument

Settle who may hold the right first: the answer changes which document you need. A primary mining licence under Cap. 123 is available only to a Tanzanian citizen, or a body corporate whose membership is composed exclusively of citizens. Small-scale operations on it work to an environmental protection plan filed with the Commission, not a Minister’s certificate. Non-citizens reach the sector through prospecting, mining and special mining licences, which carry the certificate route in full.

GN No. 487A of 2025 lists activities reserved for citizens. Read it against the precise service you intend to supply: brokerage, transport, security and labour supply sit closer to that line than mine engineering does.

What the mineral right actually carries

Each row has its own inspector, file and renewal date, and the certificate answers only the first of them.

The rehabilitation bond, and the closure plan behind it

The bond stops production more often than any other condition. It is lodged with the Commission in an accepted instrument (commonly a guarantee from a bank licensed by the Bank of Tanzania, or a bond from a TIRA-licensed insurer), and must be in place before disturbance begins, not at first pour.

Its face value follows a cost estimate, so closure planning sits upstream. The Mine Closure Guidelines issued in 2019 under section 19 of the Act put a costed, revisable plan at the centre: what the pit, dumps, tailings facility, roads, camp and plant cost to leave safe, and when. Footprint grows and rates move; a bond sized on the original pit shell is a shortfall found at renewal.

Progressive rehabilitation lowers the liability: ground re-contoured, revegetated and accepted on inspection comes out of the outstanding estimate; ground merely fenced does not. Relinquishment gives back area, never the duty to repair what was disturbed. Tax runs separately: Cap. 332 allows deductions for amounts set aside through an approved rehabilitation fund, and ring-fences results by licence area. That fund is a tax position; the bond is security a regulator can call.

Water, chemicals and radiation carry their own inspectors

Abstraction for a process plant, and any discharge back to a watercourse, are permits from the Basin Water Board for your catchment under Cap. 331. Dewatering is the recurring gap: a permit to take water says nothing about putting pit water into a seasonal river, and effluent returns fall due whether or not anyone visits.

Cyanide, mercury where lawful, acids and other industrial reagents fall to the Government Chemist Laboratory Authority, which authorises dealing, import, transport and storage. Explosives carry their own licence and a registered magazine. Radioactive sources in gauges and laboratory equipment, and natural radioactivity in some concentrates, bring in the Tanzania Atomic Energy Commission, both as source licensor and where a consignment clears for export. Pit safety runs through the mines inspectorate; offices and workshops are registrable under the Occupational Health and Safety Act Cap. 297.

Surface rights, compensation and the plan the council signs

A mineral right is not a land right. Entry onto occupied ground requires compensation assessed under Cap. 113 and approved by the Chief Government Valuer, the statutory gatekeeper since the Valuation and Valuers Registration Act, 2016. A schedule negotiated village-side and paid ahead of that approval is the most reliable way to acquire an injunction. Resettlement, where it arises, is a project of its own: household census, asset inventory, entitlement matrix, replacement housing and a grievance route, minuted at district and village level.

Cap. 123 also requires the holder to prepare a corporate social responsibility plan jointly agreed with the host local government authority. It is annual, it is scrutinised, and it is not discretionary philanthropy.

The order the desks take it

1. Read the schedule of conditions against the mine plan: line by line, a responsible manager against each.
2. Fold the management plan into the mining programme lodged with the Commission, so licence and certificate describe one mine.
3. Cost closure before costing production: an estimate built to the 2019 guidelines, tied to disturbance year by year.
4. Lodge the bond in the accepted instrument and amount, dated before first disturbance, renewal diarised.
5. Take the parallel permits: abstraction and discharge, chemicals authorisation, explosives, radiation.
6. Settle the surface: valuation signed off by the Chief Valuer, compensation paid, minutes filed.
7. Agree the social plan with the council and file it, with the local content plan, on the Commission’s cycle.
8. Diary every variation: footprint, tailings lift, process route, throughput or change of control returns to both desks first.

The papers the file needs

Instrument set: the certificate with its conditions, in the name of the entity that actually holds the right; the impact statement lodged with it; the mineral right with its programme of mining operations and approved variations; a current BRELA extract.

Operating set: closure plan and costed estimate; the bond instrument with face value, issuer and expiry; abstraction and discharge permits with monitoring returns; chemicals authorisations and reagent reconciliation records; explosives licence and magazine registration; radiation source licence; tailings design and dam safety review; the inspection register carrying the Resident Mines Officer’s entries; the approved compensation schedule; and annual social and local content filings.

Illustrative arithmetic: a bond re-valued against a growing footprint

Take an open pit disturbing 40 hectares at grant and 150 hectares by year five, at an all-in rehabilitation rate of TZS 38,000,000 a hectare covering earthworks, capping, topsoil replacement and revegetation. The estimate at grant is TZS 1,520,000,000; by year five it is TZS 5,700,000,000. A bond left at its original face value is short by TZS 4,180,000,000, a gap found at renewal. Handing back 25 rehabilitated hectares cuts the outstanding liability to TZS 4,750,000,000, and guarantee commission at 2% a year, a bank charge rather than a statutory one, costs TZS 114,000,000 on the year-five figure.

The works are a taxable supply: at 18% under the Value Added Tax Act Cap. 148 that programme grosses up to TZS 6,726,000,000, and input recovery after production ceases is worth settling early. A deductible TZS 1,000,000,000 contribution to an approved fund shelters TZS 300,000,000 at the 30% corporate rate. Illustrative arithmetic, not a quotation; confirm the live schedule on tra.go.tz.

Where this file stalls

• The certificate still names the exploration company after the right moved to a project vehicle, so the Commission reads two holders.
• A tailings facility redesigned for higher throughput and built without a variation; the inspector halts the lift mid-season.
• A closure estimate lifted from a study for a different pit shell, unrelated to the disturbance actually caused.
• Pit water pumped to a seasonal watercourse with no discharge permit and no effluent monitoring.
• Reagent delivered on supplier papers alone; the consignment sits pending authorisation.
• Compensation paid on a list assembled locally, which the Valuer’s office never endorsed; access is injuncted.

What moved since the 2017 amendments

The 2017 package (the Natural Wealth and Resources (Permanent Sovereignty) Act, 2017 and the Written Laws (Miscellaneous Amendments) Act, 2017) rebuilt the sector’s administration. The Mining Commission replaced the earlier advisory arrangement, and the duties on local content and on a jointly agreed social plan date from that reform. Subsidiary regulations made in 2018 reworked mineral rights, local content and record audit. The 2019 closure guidelines matter most here: they moved closure from a late-life topic to a costed plan that sets the bond.

Mandate-holders this file does not replace

The environment Minister issues, varies and cancels the certificate; the Council screens and monitors, and the periodic audit duty under Cap. 191 is a separate file from these licence conditions. The Commission administers the mineral right, the bond and closure. Basin Water Boards own water, the Government Chemist Laboratory Authority reagents, the Atomic Energy Commission radiation. The Chief Valuer owns compensation values; the district council owns the business licence, the service levy and the social plan it signs.

Zatra Consultants prepares, structures and coordinates the pack crossing those desks. It does not practise law, audit, engineer or value, issues no licence or approval, and promises no regulatory outcome.

What to confirm before you act

• Whether the certificate names the entity that now holds the right, and whether a transfer is outstanding.
• The exact wording of the conditions, and which of them the Commission treats as licence terms.
• Current bond face value against current disturbed area, and the date the instrument expires.
• When the closure plan was last revised, and against which pit shell and unit rates.
• Whether a discharge permit exists alongside the abstraction permit for your catchment.
• Which jurisdiction applies: Mainland, or Zanzibar under its own instruments.
