The Department must comprehensively review erosion and sediment control plans for each phase of the site design to determine compliance with this Division III.
For each plan phase, coordinated comments will be provided that reflect input from all appropriate agencies, including Planning, Zoning, and Public Works.
At each phase of project design, comments from the Department and other appropriate agencies must be addressed by the applicant and approval received before subsequent submissions.
In approving a plan, the Department may impose conditions that the Department considers necessary or appropriate to ensure:compliance with this Division III; and
the preservation of public health and safety.
After the Department has completed its comprehensive review for each phase of site design, the Department must notify the applicant of either:the Department’s approval of the plan;
the Department’s disapproval of the plan, together with:the reasons for disapproval; and
any modifications that the Department requires for approval; or
if no decision has been made:the status of the review process; and
the anticipated date of completion.
The final erosion and sediment control plan may not be considered approved without the inclusion of the Department’s dated signature on the plan.
Approved plans remain valid for 2 years from the date of approval, unless extended or renewed by the Department.
Any plans that receive final approval after January 9, 2013, must be in compliance with the requirements of this Division III and the Standards and Specifications.
A plan that receives final approval on or before January 9, 2013, may be reapproved under its existing conditions, except for stabilization requirements, if grading activities begin on the site on or before January 9, 2015.
Stabilization practices on all sites must be in compliance with the requirements of this Division III and the Standards and Specifications on or before January 9, 2013, regardless of when an approved erosion and sediment control plan was approved.
