46.1.7 “Grading” means any
excavating, grubbing, filling (including hydraulic
fill) or stockpiling of earth materials or any
combination thereof, including the land in its
excavated or filled condition.
46.1.8 “Inspection” means the
periodic review of sediment and erosion control
measures shown on the certified plan.
46.1.9 “Sediment” means solid

its site of origin by erosion.
46.1.10 “Soil” means any
unconsolidated mineral or organic material of any
origin.
46.1.11 “Soil Erosion and
Sediment Control Plan” means a scheme that minimizes
soil erosion and sedimentation resulting from
development and includes, but is not limited to, a
map and narrative.
46.2 Activities Requiring
a Certified Erosion and Sediment Control Plan: A
soil erosion and sediment control plan shall be
submitted with any application for development when
the disturbed area of such development is
cumulatively more than one-half acre.
46.3 Exemption: A
single family dwelling that is not a part of a
subdivision of land shall be exempt from the soil
erosion and sediment control regulations, provided
that it is also covered under Exclusions under
Section 44.4.
46.4 Erosion and Sediment
Control Plan:
46.4.1 To be eligible for
certification, a soil erosion and sediment control
plan shall contain proper provisions to adequately
control accelerated erosion and sedimentation and
reduce the danger from storm water runoff on the
proposed site based on the best available
technology. Such principles, methods and practices
necessary for certification are found in the
Connecticut Guidelines for Soil Erosion and Sediment
Control (1985) as amended. Alternative principles,
methods and practices may be used with prior
approval of the Commission.
46.4.2 Said plan shall contain,
but not be limited to:
A.
A narrative describing:
1. the development;
2. the schedule for grading and
construction activities including:
a. start and completion dates;
b. sequence of grading and
construct ion activities;
c. sequence for installation
and/or application of soil erosion and sediment
control measures;
d. equence for final
stabilization of the project site.
3. the design criteria for
proposed soil erosion and sediment control measures
and storm water management
facilities.
4. the construction details for
proposed soil erosion and sediment control
measures and storm water management facilities.
5. the installation and/or
application procedures for proposed soil erosion and
sediment control measures and storm water management
facilities.
6. the operations and maintenance
program for proposed soil erosion and sediment
control measures and storm water management
facilities.
B.
A site plan map at a
sufficient scale to show:
1. the location of the proposed
development and adjacent properties;
2. the existing and proposed
topography including soil types, wetlands,
watercourses and water bodies;
3. the existing structures on the
project site, if any;
4. the proposed area alterations
including cleared, excavated, filled or graded areas
and proposed structures, utilities, roads and, if
applicable, new property lines;
5. the location of and design
details for all proposed soil erosion and sediment
control measures and storm water management
facilities;
6. the sequence of grading and
construction activities;
7. the sequence for installation
and/or application of soil erosion and sediment
control measures;
8. the sequence for final
stabilization of the development site.
C.
Any other information
deemed necessary and appropriate by the applicant or
requested by the Commission or its designated agent.
46.5 Minimum Acceptable
Standards:
46.5.1 Plans for soil erosion and
sediment control shall be developed in accordance
with these regulations using the principles as
outlined in Chapters 3 and 4 of the Connecticut
Guidelines for Soil Erosion and Sediment Control
(1985), as amended. Soil erosion and sediment
control plans shall result in a development that
minimizes erosion and sedimentation during
construction; is stabilized and protected from
erosion when completed; and does not cause offsite
erosion and/or sedimentation.
46.5.2 The minimum standards for
individual measures are those in the Connecticut
Guidelines for Soil Erosion and Sediment Control
(1985), as amended. The Commission (or the County
Soil and Water Conservation District) may grant
exceptions when requested by the applicant if
technically sound reasons are presented.
46.5.3 The appropriate method
from Chapter 9 of the Connecticut Guidelines for
Soil Erosion and Sediment Control (1985), as
amended, shall be used in determining peak flow
rates and volumes of runoff unless an alternative
method is approved by the Commission.
46.6 Issuance or Denial of
Certification:
46.6.1 The Planning & Zoning
Commission shall either certify that the soil
erosion and sediment control plan, as filed,
complies with the requirements and objectives of
this regulation or deny certification when the
development proposal does not comply with these
regulations.
46.6.2 Nothing in these
regulations shall be construed as extending the time
limits for the approval of any application under
Chapters 124, 124A or 126 of the General Statutes.
46.6.3 Prior to certification,
any plan submitted to the municipality may be
reviewed by the County Soil and Water Conservation
District which may make recommendations concerning
such plan, provided such review shall be completed
within thirty days of the receipt of such plan.
46.6.4 The Commission may
forward a copy of the development proposal to the
conservation commission or other review agency or
consultant for review and comment.
46.7 Conditions Relating
to Soil Erosion and Sediment Control:
46.7.1 The estimated costs of
measures required to control soil erosion and
sedimentation, as specified in the certified plan,
may be covered in a performance bond or other
assurance acceptable to the Commission in accordance
with the provisions of these Regulations.
46.7.2 Site development shall
not begin unless the soil erosion and sediment
control plan is certified and those control measures
and facilities in the plan scheduled for
installation prior to site development are installed
and functional.
46.7.3 Planned soil erosion and
sediment control measures and facilities shall be
installed as scheduled according to the certified
plan.
46.7.4 All control measures and
facilities shall be maintained in effective
condition to ensure the compliance of the certified
plan.
46.8 Inspection:
46.8.1 Inspection shall be made by the Commission
or its designated agent during development to ensure
compliance with the certified plan and that control
measures and facilities are properly performed or
installed and maintained. The Commission may require
the permittee to verify, through progress reports,
that soil erosion and sediment control measures and
facilities have been performed or installed
according to the certified plan and are being
operated and maintained.
