(D) In the event that a project site is determined to impact or discharge to a sensitive area, the DSM and/or the permitting officer may require more stringent storm water quantity and quality measures than detailed in this chapter or in the Standards.

After the DSM and/or the permitting officer receives the application, a preliminary determination will be made whether the application is substantially complete within ten days (for projects at least one acre but less than five acres) or within 14 days (for projects greater than or equal to five acres). Notification will be provided to the applicant within the applicable time frame of one of the following:
