Permit Change – stabilization requirementsPermit Change stabilization requirements

Originally disturbed areas had to be stabilized g yaccording to the “14/21 day rule.” This has now changed to:

Where the initiation of stabilization measures by the 7th dayafter construction activity temporarily or permanently ceases on a portion of the site is precluded by snow cover, p p ystabilization measures shall be initiated as soon as practicable.

Wh t ti ti it ill ti f th itWhere construction activity will resume on a portion of the site within 14 days from when activities ceased, (e.g. the total time period that construction activity is temporarily ceased is less than 14 days) then stabilization measures do not have to be initiated on that portion of site by the 7th day after construction activity temporarily ceased.
