sludge includes, but is not limited to, domestic septage, scum or
solids removed in primary, secondary, or advanced wastewater treatment
processes; and material derived from sewage sludge. Sewage sludge
does not include ash generated during the firing of sewage sludge
in a sewage sludge incinerator or grit and screening generated during
preliminary treatment of domestic sewage in a treatment works.
(1)
DOMESTIC SEWAGEWaste and wastewater from humans or household operations that is discharged to or otherwise enters treatment works.

solids removed from domestic and industrial wastewater at a sewage
treatment plant.
TOWNSHIP
References Independence Township and/or Independence Township
Board of Supervisors or their agent.

WATER SOURCE
Site or location of well, spring or water supply stream intake
which is used for human consumption (Pa. Code, Title 25, § 271.1).
It shall be unlawful for any person to permit
or cause to be permitted the spreading or disposition of sewage sludge
for any purpose on any lands within the limits of Independence Township

permit by PA DEP.
The disposal of the sewage sludge by land application

so as to discharge into any lake, stream, pond, well or any other
waters as required by Title 25, Pa. Code.
B. No sewage sludge shall be deposited or spread on land
where the location of such shall constitute an environmental or health
hazard.
C. Any amount of sewage sludge shall be incorporated
into the land on which it is spread or deposited within 24 hours to
a depth of not less than three inches. For a no-till farmland, the
regulations for land application of sewage sludge listed in Title
25, Pa. Code, § 275.313 shall apply.
D. No properties other than the permitted site shall
be exposed to sewage sludge by any means of conveyance including airborne
particles, water or vehicle.
E. Any vehicle hauling sewage sludge in any form shall
be of such construction so as to prevent any part of the load from
spilling or leaking at all times. The operator of each vehicle must
have a current vehicle registration, vehicle safety inspection, YCSWA
license and a copy of the LAP and vehicle manifest for the contents
of that vehicle.
(1) Vehicle manifest must show the weight of the vehicle
and the weight of its contents and the source of the sludge.
(2) The transporting of sewage sludge within Independence
Township will restricted to Monday through Friday between the hours
of 8:00 a.m. and 4:30 p.m.
F. Sewage sludge shall not be deposited on any land within
Independence Township if this sewage sludge and/or soil exceeds the
following criteria:
(1) Maximum concentrations for heavy metals and PCBs,
per dry weight of sludge and soil;

sludge shall be less than one plaque-forming unit per four grams of
total solids (dry-weight basis) at the time the sewage sludge is used
or disposed.
