This standard applies to all discharges, including to sewer and to controlled waters, that result from Network Rail Maintenance delivery activities:

• Maintenance or Works Delivery works activities involving works (planned or unplanned) where discharges might be produced;

• Maintenance or Works Delivery teams involved with or responsible for activities, assets, sites or premises where discharges might be produced.

• Maintenance or Works Delivery teams that are working on or near a watercourse, including weedspraying
