A Cement Group, a Reduced Audit and a Recent Consultancy
You are the lead auditor appointed for the stage 2 certification audit of a cement group: one clinker plant with a captive 22 MW waste-heat recovery unit, two grinding stations, and a leased grinding station in a neighbouring country that produces 15% of group output. Annual energy use is 2.6 PJ, mainly coal, petcoke, electricity and alternative fuels (tyres and biomass) replacing 28% of thermal input. The certification body has planned six auditor-days across three sites; the client asks for four, arguing the audit will run alongside its ISO 14001 surveillance and that one site can be covered remotely to save travel. Two weeks ago you spent three days advising the group on kiln thermal efficiency. A technical expert in alternative fuels is available but has never audited. The client wants the leased grinding station excluded from scope because it is 'not our building'. The energy review and EnPI are centralized at headquarters.
1. Can you accept the assignment? Analyse impartiality, competence and the role of the technical expert.

Impartiality first. Three days advising on kiln thermal efficiency is consultancy, not awareness training: you analysed the client's processes and recommended improvements. ISO 17021-1 impartiality requirements prevent certification body personnel who provided consultancy to a client from auditing that client for two years after the consultancy ends. The conflict is not cured by using you only at headquarters, because the advice concerned a core significant energy use. You must decline as lead auditor and as a team member for this client; the certification body records the threat and reassigns.
Competence of the replacement team. ISO 50003 requires the team to have EnMS knowledge plus technical competence in the client's energy uses. Cement auditing requires understanding of kiln thermal efficiency, alternative fuel substitution, waste-heat recovery and grinding. A team of generic EnMS auditors is not sufficient simply because the lead auditor is experienced.
The technical expert. An expert in alternative fuels can fill a competence gap, but experts advise; they do not audit. The expert must work under the auditors' direction, must not make conformity decisions alone, must be briefed on audit methods, confidentiality and impartiality, and must not have a conflict with the client. Never having audited is acceptable if the expert is properly briefed; the audit team still needs an auditor able to evaluate the evidence the expert interprets. Record the expert's role and contribution in the report.
2. How should audit time and scope be determined, and how do you respond to the client's three requests (reduce days, remote site, exclude the leased station)?

Audit time. Under ISO 50003, EnMS audit time is determined from complexity factors such as annual energy consumption, the number of significant energy uses and the number of energy sources, not from the client's travel budget. At 2.6 PJ, with coal, petcoke, electricity, tyres, biomass, a captive power unit and four sites, six auditor-days is already lean. Integration with ISO 14001 can save time on genuinely shared elements (opening meeting, context, leadership, document control), but cannot reduce the EnMS-specific technical time. If the client insists on four days, the certification body must document the justification, or the audit will be incomplete.
Remote coverage. ICT is acceptable for interviews, document review and some headquarters activities. It is not adequate to verify kiln operation, alternative-fuel feeding, metering, calibration or SEU operational control. A site with significant energy uses should be visited. Sending one site entirely remote is a scope limitation, not a saving.
Exclusion of the leased station. Scope is determined by the organization's boundary and activities. If the leased station is under the group's operational control and its energy is inside the EnPI and baseline, excluding it from certification scope while including its energy in performance claims creates an inconsistency. If it is genuinely outside the boundary, the EnPI, baseline and energy review must exclude it too. The certificate scope must describe what was actually audited; explain this to the client and escalate to the certification body if they refuse. Document the decision and the client's request in the audit file.
3. Outline the audit plan: which sites and clauses to prioritise, and what pre-audit information you need.

Site coverage. Audit headquarters plus the clinker plant, because the clinker plant concentrates the SEUs, captive generation and alternative fuels; include at least one grinding station and audit the leased station if it remains in scope. Site types differ materially, so multi-site sampling is not defensible here.
Clause priorities at headquarters: 4.3 and 4.4 (scope and EnMS), 6.1 (risks and opportunities), 6.3 (energy review), 6.4 (EnPIs), 6.5 (baseline), 6.6 (data collection), 9.1.1 (performance evaluation), 9.2 (internal audit), 9.3 (management review), 10.2 (corrective action). At the clinker plant: 8.1 (operational control of kiln and fuels), 8.3 (procurement of fuel and equipment), 7.2 (competence of kiln operators), 9.1.1 (metering and calibration). Add 8.2 at any site with recent modification.
Pre-audit information: energy review and SEU list; EnPIs and definitions; baseline and any adjustments; energy balance and data collection plan; meter list and calibration records; fuel invoices and alternative-fuel delivery records; legal register and compliance evaluation; objectives and action plans; internal audit programme and reports; management review minutes; organization chart; leases and contracts for the grinding stations; previous certification reports.
Sampling: select meters and fuel streams by energy contribution, not convenience; trace alternative-fuel deliveries through weighbridge, contract, invoice and kiln feed; interview operators on shift. Allocate expert time to kiln and fuel sampling, and record how sampling decisions support the conclusions.
