Where fuel handling and storage at a municipal drinking water system facility is identified as a significant drinking water threat regulated under the Safe Drinking Water Act, 2002 (SDWA), the approving director under Part V of the SDWA will require the owner to assess if the storage of fuel in any part of the drinking water system is a significant threat. In order to address any significant threats, alteration of the works/operating procedures shall include:

Secondary containment;
Spill/leak detection and spill response procedures as per Condition 16 of the license;

The Director will require the owner to apply to the Ministry within 90 days of receiving the Ministry's concurrence with the assessment, to amend the Drinking Water Works Permit/License to include the required alterations/operating procedures.
Instruments that exist before the day the plan takes effect must be reviewed and, if necessary, amended within three years.
Note: Additional policies apply. See: MONITORING-3.
