Ms Mary Gurrie:

No, we do not monitor it. That is not our role. The sludge is an organic fertiliser under the good agricultural practice, GAP, regulations so it is managed under that as a fertiliser. A producer of the sludge, be that a treatment plant, a food and drink facility or those types of facilities which produce sludge, need to keep records of what they are producing and they need to have it spread under nutrient management plans and have the appropriate records. That is all managed under the GAP regulations so the Department of Agriculture, Food and the Marine and the local authorities have responsibility for the oversight of that.
