ISO 14001 Guidance - 4. Implementation and operation

4.6 Operational control

An organization should evaluate those of its operations that are associated with its identified significant environmental aspects and ensure that they are conducted in a way that will control or reduce the adverse impacts associated with them, in order to fulfil the requirements of its environmental policy and meet its objectives and targets. This should include all parts of its operations, including maintenance activities.

As this part of the environmental management system provides direction on how to take the system requirements into day-to-day operations, 4.4.6 a) requires the use of documented procedure(s) to control situations where the absence of documented procedures could lead to deviations from the environmental policy and the objectives and targets.
