Exam ISO-14001-Lead-Auditor Topic 4 Question 17 Discussion

You are conducting a Stage 2 certification audit of VitalSpark, a pharmaceutical organisation manufacturing vitamins and other healthcare medicines. In a separate area in the centre of their large site, a supplier produces oxygen supplies piped directly into the manufacturing processes of VitalSpark. They also deliver oxygen in bulk tankers to other customers. When you review the environmental aspects register, you find that the only environmental aspect recorded for this arrangement relates to the heavy goods vehicles of the supplier transiting the site.
You ask the EMS Manager about the environmental consequences to VitalSpark of this arrangement and are told that they are not significant since the supplier has its own services for water, sewage, waste and energy.
The EMS Manager tried unsuccessfully to communicate with the supplier who is located inside the VitalSpark site and outside the scope of the EMS.
You raise a non-conformance against clause 6.1.2 of ISO 14001:
"VitalSpark does not maintain documented information on aspects/impacts related to activities, products and services of the oxygen supplier." Which combination of two of the following actions proposed by VitalSpark would permit you to close out the nonconformity?
