"intrusive exploration" refers to drilling and trenching and does not include geochemical or geophysical surveys, stream or soil sampling or general prospecting.
"residential building" refers to the principle dwelling in which people live (ie. house, apartment building, rooming or boarding house, mobile home, nursing home, senior citizen's home, etc.).
"institutional building", buildings devoted to the work of organized establishments, foundations, societies, or the like (eg. hospitals, schools, stores, etc.).
- Uranium exploration, uranium extraction and uranium mining operations are no longer permitted in designated watersheds or wellfields, used as a source of water for a public water supply system;
- Prospecting or staking for uranium minerals shall not take place within municipalities (cities, town or villages) as defined within section 1 of the Municipalities Act;
- Intrusive uranium exploration or mine development work that damages or interferes with the use and enjoyment of the land shall not take place on land defined as residential under the Assessment Act without the landowner's permission, however, this will not include industrial freehold or Crown land;
- Intrusive uranium exploration or development shall not take place within 300 metres of residential or institutional buildings.
When trenching or drilling for uranium is undertaken or where uranium may be encountered during exploration for other minerals:
- Following the backfilling of a trench, a radiometric survey must be conducted to ensure that radiation is reduced to background levels for the area. When material is found to exceed background levels, the Recorder must be contacted for review and approval of handling and reclamation procedures;
- For drill holes that encounter uranium mineralization, with measurable radioactivity above local background levels, drill mud solids and cuttings are to be collected and returned down the drill hole, following which, the drill hole shall be grouted with bentonite along their entire length (Note: the company shall note where the depth at which water bearing zones are encountered to ensure that drill cuttings are not placed adjacent to these zones);
- Drill core with uranium mineralization or measurable radioactivity (as noted by visible inspection and logging, radiometric readings, or laboratory analysis) shall be noted by clearly marking on the outside of the associated core box with yellow paint markings;
- Core with uranium mineralization or measurable radioactivity shall be stored in secured areas or buildings to prevent public access;
- Decommissioning of core storage areas shall require that gamma radiation levels measured at 1 metre from the surface for a storage area should be reduced to 1.0 μSv and in no instance will the level be allowed to exceed 2.5 μSv. When core is found to exceed these levels then the Recorder must be contacted for review and approval of handling procedures.
