"sewage" means household and commercial wastewater that contains human waste;
"total coliform" means a group of aerobic and facultative anaerobic, Gram-negative, nonspore-forming, rod-shaped bacteria, that ferment lactose with gas and acid formation within 48 hours at 35o C, and inhabit predominantly the intestines of man or animals, but are occasionally found elsewhere and include the sub-group of fecal coliform bacteria;
"wastewater" means the spent or used water of a community or industry which contains dissolved and suspended matter;
"wastewater treatment lagoon" means the component of the development which consists of an impoundment into which wastewater is discharged for storage and treatment by natural oxidation.
GENERAL TERMS AND CONDITIONS
This Section of the Licence contains requirements intended to provide guidance to the Licencee in implementing practices to ensure that the environment is maintained in such a manner as to sustain a high quality of life, including social and economic development, recreation and leisure for present and future Manitobans.
- the release of offensive odours is minimized;
- the organic loading on the primary cell, as indicated by the five-day biochemical oxygen demand, is not in excess of 56 kilograms per hectare per day; and
- the depth of liquid in the primary cell or secondary cells does not exceed 1.5 metres.
- notify the Director immediately;
- identify the repairs required to the wastewater collection and/or treatment system;
- undertake all repairs to minimize unauthorized discharges of wastewater; and
- complete the repairs in accordance with any written instructions of the Director.
- file a notice of alteration to construct an additional secondary cell, or other plans, with the Director prior to commencing construction;
- construct the additional secondary cell in accordance with this Licence;
- complete all the required soil testing in accordance Clauses 13, 14 and 15 of this Licence; and
- place the additional secondary cell into operation.
SPECIFICATIONS, LIMITS, TERMS AND CONDITIONS
- remove all organic topsoil from the area where the dykes will be constructed; or
- remove all organic material for a depth of 0.3 metres and a width of 3.0 metres from the area where the cut-off will be constructed.
- the liner shall be made of clay;
- the liner shall be at least one metre in thickness;
- the liner shall have a hydraulic conductivity of l x l0-7 centimetres per second or less; and
- the liner shall be constructed to an elevation of 2.5 metres above the floor elevation of both the primary and the secondary cells.
- where the organic content of the effluent, as indicated by the five day biochemical oxygen demand, is in excess of 30 milligrams per litre;
- where the fecal coliform content of the effluent, as indicated by the MPN index, is in excess of 200 per l00 millilitres of sample;
- where the total coliform content of the effluent, as indicated by the MPN index, is in excess of 1500 per 100 millilitres of sample; or

Soil Sampling:
Soil Testing Methods:
- The soil samples shall be tested for hydraulic conductivity using ASTM D 5084 (Standard Test Method for Measurement of Hydraulic Conductivity of Saturated Porous Materials Using a Flexible Wall Permeameter).
- Soil specimens shall have a minimum diameter of 70 mm (2.75 inches) and a minimum height of 70 mm (2.75 inches). The soil specimens shall be selected from a section of the soil sample which contains the most porous material based on a visual inspection. The hydraulic gradient shall not exceed 30 during sample preparation and testing. Swelling of the soil specimen should be controlled to adjust for: the amount of compaction measured during sample collection and extraction from the tube and the depth or elevation of the sample. The effective stress used during saturation or consolidation of the sample shall not exceed 40 kPa (5.7 psi) or the specific stress level, that is expected in the field location were the sample was taken, which ever is greater.
- The complete laboratory report, as outlined in ASTM D 5084, shall be supplied for each soil sample collected in the field.
- The soil samples shall be tested for hydraulic conductivity using ASTM D 2435 (Standard Test Method for One-Dimensional Consolidation Properties of Soils).
- Soil specimens shall have a minimum diameter of 50 mm (2 inches) and a minimum height of 20 mm (0.8 inches). The soil specimens shall be selected from a section of the soil sample which contains the most porous material based on a visual inspection. The soil specimen shall be taken from an undisturbed soil sample. The soil specimen shall be completely saturated.
- The complete laboratory report, as outlined in ASTM D 2435, shall be supplied for each soil sample collected in the field.
