To maintain the effectiveness of any features installed to prevent watercourse pollution.
Are bunded areas, light-liquid separators and grease separators effectively maintained?
|Criterion||Assessment criteria||Applicable answer|
Where no bunded areas are required (as no liquids requiring bunded storage are stored on-site) or the asset does not require light-liquid separators or grease separators, the associated credits can be filtered out of the assessment.
