Code	Label	Definition
NP		Total Diffuse Emissions to Inland Waters
NP1		Agricultural Emissions
NP2		Atmospheric Deposition
NP3		Un-Connected Dwellings Emissions
NP4	Refers only to those emissions of pollutants in urban runoff that are not connected to a collecting system.	Urban Diffuse Emissions
NP5	Refers to discharges/emissions to a receiving water following exceedance of the storage capacity of the collecting/treatment system during heavy ‘storm’ rainfall. Ideally, this discharge should be separate from that referred to under ‘Urban Waste Water Treated’ but if data are only available as combined then please flag.	Storm Overflow Emissions
NP6		Abandoned Industrial Site Emissions
NP7		Other Diffuse Emissions
NP8		Background Emissions
