- with a depth of clay or clay till of less than 1.5 metres between the soil surface and the water table;
- within 100 metres of an identifiable boundary of an aquifer which is exposed to the ground surface;
- where, prior to the application of biosolids, the soil pH is less than 6.0;
- where the surface slope of the land is greater than 5 percent;
- where, prior to the application of biosolids, the level of nitrate-nitrogen exceeds 100 kilograms per hectare in the upper 60 centimetres of the soil; or

SCHEDULE "B" TO ENVIRONMENT ACT LICENCE NO. 2363
The analysis for all metals shall be carried out in accordance with the following requirements:
- Samples of reference material shall be analyzed to monitor the accuracy of the sludge and soil analyses and each set of ten of less samples of sludge or soil shall include, a minimum of the following:
- For sludge samples:
- one USEPA Municipal Digested Sludge sample;
- For soil samples:
- one NIST Estuarine Sediment sample (SRM 1646 or suitable replacement whose analyte concentrations reflect that found in the samples); and
- one of three ECSS soil samples (Nos. 2, 4, and 7) which best reflects local soil conditions. (The three ECSS soil samples are available from Agriculture Canada, Land Resource Centre, Central Experimental Farm, Ottawa);
- Field duplicates of samples shall be analyzed based on a frequency of one in each set of ten or less field samples and that the acceptance criteria for duplicate analysis should be within ± 10 percent.
