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.
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 I qik=?3 and how the impact will be mitigated.
Pl ase provide documentation from the NCEEP indicating their willingness to accept your request to purchase
?f uq?( (type of mitigation) credit to mitigate for the proposed 0. .i (type of
mitigation) impacts listed in your PEPapplication , 2.

? Please provide BMP Supplement for the proposed on the site plan.
? Please provide BMP Supplements for every proposed BMP on your site. The Supplement forms (including the Required Items
Checklist) can be found at: http:hh2o.enr.state.nc.us/su.-bmp fornis.htni.
? Please use the most current version of the BMP Supplement available on the DWQ website at
http:'/I12o.enr.state.nc.us/su-bmp forms.htm. The submitted version is outdated.
? Please redesign your BMP to comply with the 2007 DWQ Stormwater BMP manual (current revisions can be
found at: http://h2o.enr.state.nc.us/su/bmp_forms.htm).
? Please complete all items in Part I of the BMP Supplement form: Project Information.
? Please include all information list in Part II of the BMP Supplement form: The Required Items Checklist was
not included in your original submittal.

(Supplement forms available on the DWQ website at http:!!h2o.enr.state.nc.us/su'bmpFforms.htm).
? Please provide calculations to show the outlet velocity to ensure that a non-erosive velocity will be achieved for
the 10-year storm. This should include the delineated drainage area, percent imperviousness, peak flow calculations for the 10-
year storm, cross-section, and longitudinal slope.
? The slope from the proposed level spreader(s) lip ( ) to the top of bank of the stream exceeds the maximum
allowable slopes for level spreaders (6% for wooded vegetation and 8% for thick ground cover and grass). If an appropriate area
for level spreader(s) cannot be found then another BMP such as a bioretention area must me proposed.

Per the requirements of the Neuse Riparian Buffer Rule, all stormwater drainage
from this site must meet the state's diffuse flow requirements as set forth in
Chapter 8 of the North Carolina Stormwater BMP Manual, available at:
http://h2o.enr.state.nc.us/su/bmp forms.htm Please provide one Level Spreader
Supplement Form for each proposed level spreader, available at:
http://h2o.enr.state.tic.us/su/bmp fonns.htm. Please include the Required Items
checklist and all items listed therein. If the filter strip is too steep for a level
spreader in any location, then you must provide a BMP that removes a minimum
of 85 percent TSS and 30 percent TN from the stormwater generated by this
project. For each proposed BMP, please provide a completed BMP Supplement
Form, with all the required items. The BMP Supplement Forms are also available
at the above web site.
2. Please provide a conceptual stormwater management plan for the project that
includes the following:
a. A depiction of the drainage areas on the site.
b. An estimation of the percentage imperviousness associated with each of
the drainage areas.
c. A calculation of the water quality volume associated with each drainage
area.
d. A depiction of a proposed BMP (state the type of BMP you plan to use) on
the site plan that is correctly sized based on the water quality volume.
Please include the following language as a permit condition:
Please provide documentation of Johnston County's approval of the stormwater
management plan for this project by providing EITHER:
• A valid approval letter from Johnston County indicating that the proposed
activity has an approved SMP and one copy of the approved SMP, including
plan details, calculations and other supporting information, OR
A set of stormwater plan details and calculations stamped as "Approved" by
Johnston County.
