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.
Incidence of Non-Compliance
Sites should report pMAJOR non-compliance issues pwhich have occurred onsite.

Importance of upholding permit i trequirements
The most common non-point source pollutantsThe most common non point source pollutants in Illinois are nutrients and sediment.Loss of sediment into local streams and riversLoss of sediment into local streams and rivers can cause:
Sediment carries other harmful pollutants like heavy metals p yand toxinsLoss of recreational useH fi h l t d i l th t l l l b diHarm fish, plants and animals that rely on local bodies of waterNutrient loading and depleted Oxygen levelsNutrient loading and depleted Oxygen levels
