from PA DEP. The sewerage facilities shall be constructed under the
developer's expert engineering supervision and competent inspection.
(2)
The Public Sewer System shall have adequate foundation support as
soil conditions require. Trenches shall be backfilled such that the
sewers will have proper structural stability, with minimum settling
and adequate protection against breakage. Concrete used in connection
with these sewers shall be protected from injury by water, freezing,
drying or other harmful conditions until cured.
(3)
Manhole inverts shall be so formed as to facilitate the flow of the
sewage and to prevent the standing of sewage solids, and the whole
manhole structure shall have proper structural strength and be so
constructed as to prevent undue infiltration, entrance of the street
wash or grit, and to provide convenient and safe means of access and
maintenance.
(4)
No stormwater from pavements, area ways, roofs, foundation drains

when explosives are to be used.
(8)
Cross connections between the potable water supply and the public
sewer system constitute a potential danger to the public health. Therefore,
all direct and indirect connections whereby under normal or abnormal
conditions the potable water supply may become contaminated from an
inferior water supply from any part of a sewerage system is hereby
specifically prohibited. The developer is further warned against permitting
to be made permanent or temporary connection with a potable supply
designed to be held in place while being used for flushing or other
purposes, and is also cautioned against the danger of back siphonage
through portable hose lines and similar avenues of possible contamination.

the elevation of the manhole frame and cover shall be 1/8 inch to
1/4 inch below the adjoining roadway surface.
G.
The Municipal Engineer or his designated representative shall observe
all connection work to existing sanitary sewers. In general, only
poured-in-place manhole bases shall be constructed on existing sewers.
Precast bases may be used on low-flow lines with pipes tied off or
bypassing pumping used with prior approval of the Engineer.
H.
After all site work has been completed, should any sanitary sewers
be subject to inflow, the municipality will require the developer
to furnish plastic manhole inserts.
I.
All eight-inch diameter sanitary sewer main and six-inch diameter
lateral work will be subject to periodic observations by representatives
of the Municipal Engineer and the municipality's sewer maintenance
personnel. All testing will be conducted in the presence of the Engineer
or his designated representative. The cost of all inspections will
be borne by the developer.

to attend a preconstruction conference with the developer's contractor.
B.
All applicable SESPC facilities shall be in place and approved by
the County Conservation District prior to the public sewer system
installation.
C.
By approval of the plans, neither the Commonwealth of Pennsylvania,
PA DEP, or the municipality assumes any responsibility for the feasibility
of the plans or the operation of the measures and facilities to be
constructed thereunder.
D.
If at any time the SESPC activities undertaken pursuant to a permit
or the discharge of the effluent therefrom is causing or contributing
to pollution of the waters of the commonwealth, the developer shall
forthwith adopt such remedial measures as are acceptable to the Department.
E.
A permit or approval does not authorize any earth disturbance controlled
by an ordinance enacted by a local municipality. Additional permits
must be secured from local municipalities where earthmoving activities
are covered by local ordinances.
F.
The developer's contractor shall have his SESPC plan available
at the site of the activity at all times. All earthmoving activities
shall be undertaken in the manner set forth in the plan identified
with this permit. Revisions to the plan shall be approved by PA DEP.
G.
The SESPC measures and facilities shall be constructed under the
supervision and competent inspection of an individual trained and
experienced in erosion control, and in accordance with plans, designs

of this permit. Control facilities shall be frequently inspected to
insure effective control.
H.
When erosion control measures and facilities are completed, the developer
shall notify the York County Conservation District so that an inspection
of the measures and facilities may be made by a representative of
the County Conservation District.

No stormwater, sewage or industrial wastes shall be admitted to the
erosion and sedimentation measures and facilities without the approval
of PA DEP.
J.
Sediment shall at no time be permitted to accumulate in sedimentation
basins to a depth sufficient to limit storage capacity or interfere

handled and disposed of in a manner that will not create pollution
problems and so that every reasonable and practical precaution is
taken to prevent said material from reaching the waters of the commonwealth.
K.
All slopes, channels, ditches or any disturbed area shall be stabilized
as soon as possible after the final grade or final earthmoving has
been completed. Where it is not possible to permanently stabilize
a disturbed area immediately after the final earthmoving has been
completed or where the activity ceases for more than 20 days, interim
stabilization measures shall be implemented promptly.
L.
Upon completion of the project, all areas which were disturbed by
the project shall be stabilized so that accelerated erosion will be
prevented. Any SESPC facility required or necessary to protect areas
from erosion during the stabilization period shall be maintained until
stabilization is completed. Upon completion of stabilization, all
unnecessary or unusable control measures and facilities shall be removed,
the areas shall be graded and the soils shall be stabilized.
M.
The responsibility of carrying out the permit conditions shall rest
with the developer or other responsible manager of earthmoving that
affects the approved erosion controls.
