Common Issues on Plans

For Level II Introduction to Design
Certified Plan Reviewers and Certified Design Professionals
Issued May 2009
1
Phasing
• Phasing cannot be done
on one sheet, it is to be
broken down into three
separate sheets.
• Where there is no mass
grading and BMPs are
the same for all three
phases, the plan may
combine all of the BMPs
into a single phase plan.
2
Excavated Sd2s
• Not to exceed one acre
3
Sediment storage
• Sediment storage
ponds can not be
labeled both Sd3 and
Rt at the same time.
• Sediment storage is
to be calculated per
acre drained, not per
the disturbed area
4
Ponds can not
be labeled
temporary and
permanent at
the same time
5
Sediment Storage
• When designing an Sd3 be
sure it is in the appropriate
location.
• When a sediment basin is
not to be used, provide a
written rationale explaining
the decision to not use a
basin.

Dn1 Calculations

Double check the plans before submittal
•Make sure to label
all BMPs
•Make sure to label
proposed contours
9
Limits of disturbance
• Label your limits of
disturbance on each phase
• Do not show work outside
the limits of disturbance
• Most common items seen
outside limits of disturbance
Silt fence
Sediment storage
Stock pile areas
Check dams
10
Example outside limits
11
State Waters
•Label all State Waters.
•Be sure statements match
plans.
•Make sure to label the State’s
required 25’ buffer along with
the LIAs buffer (if applicable).

13
Make sure to have all appropriate statements signed
" I certify that the permittee's Erosion, Sedimentation and Pollution
Control Plan provides for an appropriate and comprehensive system of best
management practices required by the Georgia Water Quality Control Act
and the document "Manual for Erosion and Sediment Control in Georgia"
(Manual) published by the State Soil and Water Conservation Commission
as of January 1 of the year in which the land-disturbing activity was
permitted, provides for the sampling of the receiving water(s) or the
sampling of the storm water outfalls and that the designed system of best
management practices and sampling methods is expected to meet the
requirements contained in the General NPDES Permit No. GAR
10000_."
"I certify under penalty of law that this Plan was prepared after a site visit
to the locations described herein by myself or my authorized agent, under
my supervision."
14
Design Professional Inspection
The Design Professional
must inspect the
installation of initial
sediment storage
requirements and
perimeter control BMPs
within 7 days after
installation.
15
Select the Appropriate Checklist
The appropriate checklist must be
completed and submitted with all
ES&PC plans.
Checklists are available at
www.gaepd.org
and
www.gaswcc.georgia.gov
16
Retention of Records
Permittees are required to retain the following records:
17
In accordance with V.G.2.d, the Permittee must
sign the following statement:
" I certify under penalty of law that this document and all attachments were
prepared under my direction or supervision in accordance with a system
designed to assure that certified personnel properly gather and evaluate the
information submitted. Based on my inquiry of the person or persons who
manage the system, or those persons directly responsible for gathering the
information, the information submitted is, to the best of my knowledge and
belief, true, accurate, and complete. I am aware that there are significant
penalties for submitting false information, including the possibility of fine
and imprisonment for knowing violations."
18
Appropriate
Worksheets
Design Professionals must
provide all the appropriate
worksheets from the manual
for structural BMPs.
19
• Make sure to have the Level II certification on each ES&PC
sheet (including details).
• Check the details to ensure that there are details for every
BMP used.
• Make sure all statements apply to your plans.
• Double check your plans for things you might have missed.
