One nutrient management strategy was approved in areas where the application, storage or handling of ASM would be a significant drinking water threat in the Central Lake Ontario, Credit Valley, Toronto Source Protection Area in 2023. However, the vulnerable area only overlapped crop land and did not contain ASM generating or storage facilities. Conditions were put on the approval to ensure no future ASM storage/OCA/yard was established in the vulnerable area without OMAFRA approval.

Policy Text:

1) The storage of ASM shall be prohibited where the activity would be a significant drinking water threat in any of the following areas:

WHPA-A (future); or
WHPA-B (VS = 10) in an Issue Contributing Area for Nitrates or Pathogens (future); or
WHPA-E in an Issue Contributing Area for Nitrates or Pathogens (future).

2) Where the storage of ASM is in an area where the activity is, or would be, a significant drinking water threat, the Nutrient Management Plan or Strategy that governs the activity shall be reviewed or established to ensure appropriate terms and conditions are included so that the activity ceases to be, or does not become, a significant drinking water threat in any of the following areas:

WHPA-A (existing); or
WHPA-B (VS = 10) which is not in an Issue Contributing Area for Nitrates or Pathogens (existing, future); or
WHPA-E (VS = 8) which is not in an Issue Contributing Area for Nitrates or Pathogens (existing, future); or
WHPA-B (VS = 10) in an Issue Contributing Area for Nitrates or Pathogens (existing); or
WHPA-E in an Issue Contributing Area for Nitrates or Pathogens (existing); or
the remainder of an Issue Contributing Area for Nitrates or Pathogens (existing, future).

Timelines:
T-1: Prescribed Instruments (existing) shall be reviewed (and amended, as necessary) within 3 years of the date the Source Protection Plan takes effect, or such other date as the Director determines.
T-3: The relevant Ministry shall comply with the Prescribed Instrument policy (future) immediately upon the date the Source Protection Plan takes effect.

Monitoring Text:

(MON-4) The provincial ministry shall, by February 1 of each year, prepare and submit a report to the Source Protection Authority on the actions taken in the previous calendar year to achieve the outcomes of the source protection policy. Reporting shall include information related to the effectiveness of the policies in ensuring a threat ceases to be, or does not become significant, and any actions required to respond to a drinking water threat during the reporting period.
