Environmental Audits After the Certificate: What Cap. 191 Still Wants

This page is the post-certificate environmental audit operating file: which reports a certified project produces, who may sign them, and what happens when they do not arrive. It is not a screening guide for projects yet to apply, nor a manual for mineral-right conditions.

• Whether the project needed a certificate: screening, study, certificate
• Who signs it, who administers it: NEMC administers; the Act names the issuer
• Plants carrying the heaviest conditions: copper and nickel battery metals
• The parallel utility file: an industrial power connection

As at 14 September 2026. This file rests on Cap. 191 and the regulations made under it; confirm the live cycle, forms and charges with the National Environment Management Council on nemc.go.tz and with the Vice President’s Office: Division of Environment.

What the certificate grants, and what it keeps demanding

An environmental impact assessment certificate is permission to build and run one described project on one described site, subject to the schedule of conditions attached to it. Those conditions are the operative part. They fix what you measure, at what frequency, against which limits, what you owe the neighbouring community, and how the site is left at closure.

The assessment feels like a project in itself (consultants, hearings, a review panel), so the signature reads as a conclusion. It is an opening. From that date the Council holds a file that expects to be fed.

Mainland and Zanzibar answer to different authorities

Environment is not a Union matter. A Mainland project reports to NEMC, an institution of the Vice President’s Office, through its Dar es Salaam head office or the zonal office covering the region. A project on Unguja or Pemba sits under Zanzibar’s Environmental Management Act No. 3 of 2015 and answers to the Zanzibar Environmental Management Authority. Neither body accepts the other’s paperwork: a group working both sides of the channel runs two cycles against two registers of experts.

The returns the Council expects after approval

The Fourth Schedule to the amended regulations sets monitoring and auditing out as a step of the same procedure that produced the certificate, splitting the work between Council and developer. The control audit costs nothing to commission and everything to fail.

The audit is scored against your own management plan

An audit here is not a general opinion on how clean a factory looks. It is a line-by-line test of the environmental and social management plan bound into the statement the Minister approved. If that plan promised dust suppression on the haul road, a grievance desk staffed on named days, effluent below a stated limit, and a tree-replacement count, those are the lines scored: compliant, partially compliant, or not.

Operators who never reread their statement discover this late: promises a consultant made for a review panel bind the plant manager who never saw them. Extract every promise into a register with an owner and a date and treat it as the audit scope. The auditor builds the same list from the same document, and the gap between the two is your exposure.

Who may sign the report, and who may test the samples

The report must carry an environmental expert registered by the Council under the Environmental (Registration of Environmental Experts) Regulations, GN No. 348 of 2005, in a category covering the work. An in-house safety manager, however competent, cannot stand in. Firms are registered as well as individuals, and registrations lapse: verify the number in the month you engage.

Laboratory results attract the same scrutiny: effluent, emission, noise and groundwater figures should come from an accredited laboratory, with chain-of-custody paperwork and calibration certificates for field instruments. The Government Chemist Laboratory Authority is the reference point where industrial and hazardous chemicals are analysed. Before appointing a foreign-owned consultancy, check the reserved-activities list at GN No. 487A of 2025 as well as the register: approval as an expert and eligibility to trade in the activity are separate questions.

The audit year, in the order the desks take it

1. Re-read the certificate in January, not the month the report falls due, and copy its conditions verbatim into a dated compliance register naming who answers for each.
2. Rebuild the monitoring plan from the approved statement (points, parameters, frequencies, limits), then check the sampling actually running on site against it.
3. Engage the registered expert early, so the auditor specifies the data before it is collected rather than working with whatever exists.
4. Sample through the year at the stated intervals, filing laboratory certificates, custody forms and calibration records as issued.
5. Close out the previous cycle’s findings with dated evidence; that is the first thing any auditor tests.
6. Put the report to the board before lodgement. It is a statement about the company’s compliance, signed on its behalf.
7. Lodge under a covering letter, pay any charge against a Government Electronic Payment Gateway control number, and copy the district environmental management officer.

The pack that goes in with the report

A report arriving without its supporting file gets acknowledged, not accepted. Assemble the certificate with its full schedule; the approved impact statement and the plans inside it; the expert’s registration certificate and engagement letter; laboratory reports with accreditation references; custody forms and calibration certificates; waste transfer notes with the licensed handler’s permit; the incident and spill log; water use and discharge permits from the basin water board; the certificate of occupancy or derivative right for the site; last cycle’s report with close-out evidence; the grievance register and community-meeting minutes; and the payment receipt.

Those last two are the usual gaps, and documentary failures rather than environmental ones.

Illustrative arithmetic for one cycle

Take a 250-worker beverage plant with three effluent points, six air and noise stations and two monitoring boreholes. Quarterly effluent sampling gives 12 suites; at an assumed TZS 420,000 each, TZS 5,040,000. Air and noise twice a year across six stations gives 12 runs; at an assumed TZS 260,000 each, TZS 3,120,000. Groundwater twice at two boreholes gives four samples; at an assumed TZS 480,000 each, TZS 1,920,000. Measurement therefore costs TZS 10,080,000. Add an assumed TZS 12,000,000 for the expert’s site work and report and the year budgets at TZS 22,080,000 before the Council’s own charges: roughly TZS 1,840,000 a month. Illustrative arithmetic, not a quotation.

The instructive half is the TZS 10,080,000, which cannot be bought in arrears. Skip the sampling, commission the report in the eleventh month, and you still pay the TZS 12,000,000 for a document resting on one day of readings. Full price, no evidence, report returned.

When the project changes, the certificate does not follow

The certificate describes a project. Debottleneck the line, add a furnace, switch solvent, take on a neighbouring plot or move the discharge point, and the description stops matching the plant. The audit then documents something never assessed, which is a worse position than a late report. Refer changes of scale or process back before they are built, and the Council decides whether a supplementary study is needed.

Ownership changes carry the same discipline. A share purchase leaves the certificate standing but describing a company that has moved; an asset purchase raises the question of what actually transferred. Either way the change belongs on the Council’s file, and the sale agreement’s environmental warranties should be drafted against the audit history, not the certificate alone.

Where this file stalls

• The report restates the impact study instead of scoring the commitments inside it, so no finding traces back to a condition.
• The signing expert holds a category that does not cover the sector, or a registration that expired mid-engagement.
• Social commitments (a water point, an access road, a training programme) were priced into the statement and never funded.
• The discharge permit lapsed at the basin water board while the environmental file stayed clean, and the auditor records an unlicensed outfall.
• Hazardous waste left the site with an unlicensed carrier, paid in cash, with no transfer note written.
• Complaints were settled verbally at the gate, so the grievance register shows a quiet year nobody can evidence.
• A contractor’s camp or borrow pit, outside the operator’s own systems, produces the finding that stops everything.

What the Council can do when nothing arrives

Environmental inspectors appointed under Cap. 191 may enter premises, take samples and require records. On finding breach, the Council’s instruments run from written compliance directions through prohibition and restoration orders, and the certificate itself can be suspended or revoked on the Minister’s authority. Offences carry fines and imprisonment; do not budget against a penalty figure from memory, since those schedules have been amended.

For a financed project the statutory sanction is rarely the expensive one: a suspension notice is a notifiable event under most facility agreements, a disclosure item for lenders applying international performance standards, and a question at insurance renewal.

Desks this file does not replace

The Council administers the environmental file; the Act names the Minister as issuer. Workplace conditions belong to the Occupational Safety and Health Authority under Act No. 5 of 2003, with its own inspection cycle. Fire safety belongs to the Fire and Rescue Force. Abstraction and effluent discharge belong to the basin water board under the Water Resources Management Act No. 11 of 2009. Chemical handling belongs to the Government Chemist Laboratory Authority. Mineral rights carry their own environmental conditions under the Mining Commission: a separate file. District environmental management officers inspect locally, and arrive unannounced.

What to confirm before you act

• The audit interval and lodgement address printed in your own schedule of conditions.
• Your expert’s current registration number and category on the Council’s register.
• Whether any change to capacity, process, footprint or ownership has been notified.
• Which laboratory accreditation the Council accepts for each parameter reported.
• Live charges and the control number to pay against, checked on nemc.go.tz.
• For an island site, the ZEMA cycle, which does not run on Cap. 191.

Zatra prepares and coordinates the compliance register, the document pack and the lodgement sequence. It does not audit, sign an expert’s report, or issue a certificate; that hand-off is made in the open.
