the site or contact DWQ to schedule intermittent/perennial stream determinations on the site.
^ Please provide a qualitative indirect and cumulative impact analysis for the project.
^ For areas in nutrient sensitive waters or buffered river basins fertilizer specifications for stormwater BMPs should state
that that only an initial minimal application of fertilizer to establish the plants shall be used.

Mitigation
^ of compensatory mitigation is required for this project. Please provide a
compensatory mitigation plan. The plan must conform to the requirements of 15A NCAC 2H .0500 and must be
appropriate to the type of impacts proposed.
^ Please indicate which 404 Permit the USACE has authorized for this project.
^ Buffer mitigation is required for all road crossings that impact 150 linear feet of riparian buffer or more. Please submit a
mitigation plan detailing the amount of buffer impact at crossing and how the impact will be mitigated.
Stormwater
^ Please provide worksheets for the proposed on the site plan.
^ Please indicate the diffuse flow provision measures on the site plan and submit diffuse flow provision measure
worksheets and signed and a notarized Operations and Maintenance Agreement.
^ Please show detailed plans and profiles for all proposed stormwater management devices.
^ Please redesign your level spreader design(s) to reflect the January 1, 2007 DWQ guidelines.
^ Please specify your soil material and source for the extended detention wetlands. On-site soils may be unsuitable for use
as a wetland both in terms of soil type and the amount of nutrients contained in the soils (particularly if former
agricultural lands).
