(3) The Erosion and Sediment Control Plan shall be prepared by
a person trained and experienced in erosion and sediment control methods and
techniques, and shall be designed to minimize the potential for accelerated
erosion and sedimentation.
(4) Earth disturbance activities shall be
planned and conducted to minimize the extent and duration of the
(5) The Erosion and Sediment Control Plan
shall contain the following:
(i) The existing
topographic features of the project site and the immediate surrounding area.
(ii) The types, depth,
slope, locations and limitations of the soils.
(iii) The characteristics
of the earth disturbance activity, including the past, present and proposed
land uses and the proposed alteration to the project site.
(iv) The amount of runoff
from the project area and its upstream watershed area.
(v) The location of waters
of this Commonwealth which may receive runoff within or from the project
site and their classification pursuant to Chapter 93.
(vi) A written depiction
of the location and type of perimeter and onsite BMPs used before, during
and after the earth disturbance activity.
(vii) A sequence of BMP
installation and removal in relation to the scheduling of earth disturbance
activities, prior to, during and after earth disturbance activities.
(ix) Plan drawings.
(x) A maintenance program
which provides for inspection of BMPs on a weekly basis and after each
measurable rainfall event, including the repair of the BMPs to ensure
effective and efficient operation.
(xi) Procedures which
ensure that the proper measures for the recycling or disposal of materials
associated with or from the project site will be undertaken in accordance
with this title.
(6) Where an earth disturbance activity may
result in a discharge to a water of this Commonwealth classified as High
Quality or Exceptional Value pursuant to Chapter 93, the person proposing
the activity shall, as applicable, use the following Special Protection BMPs
to maintain and protect the water from degradation:
(i) Special sediment basin
spillways shall be designed to skim water from the top 6 inches (15
centimeters) of the dewatering zone, or shall have permanent pools greater
than or equal to 18 inches (46 centimeters) deep.
(B) The basin
shall be designed with a flow length to basin width ratio of 4:1 or greater.
(C) The basin
shall be designed so that it dewaters in at least 4 days and no more than 7
days when at full capacity.
(ii) Channels, collectors
and diversions shall be lined with permanent vegetation, rock, geotextile or
other nonerosive materials.
(iii) BMPs that divert or
carry surface water shall be designed to have a minimum capacity to convey
the peak discharge from a 5-year frequency storm.
(iv) Upon completion or
temporary cessation of the earth disturbance activity, or any stage thereof,
the project site shall be immediately stabilized.
(v) The Department or
county conservation district may approve alternative BMPs which will
maintain and protect existing water quality and existing and designated
(7) The Erosion and Sediment Control Plan
shall be available for review and inspection by the Department or the county
conservation district at the project site during all stages of the earth
(8) Upon complaint or site inspection, the
Department or county conservation district may require that the Plan be
submitted for review and approval to ensure compliance with this chapter.
(c) The Department or county conservation district may
require other information necessary to adequately review a plan, or may
require additional BMPs, on a case-by-case basis, when necessary to ensure
the maintenance and protection of water quality and existing and designated
* By law if disturbing more than 5
acres or 1 - 5 Acres with a point source discharge the District will need to review and approve the
E&S plan and issue the NPDES permit before earthmoving
can begin. Also, a plan approval maybe required by the
township ordinance prior to work starting.
