of 15 consecutive days, while simultaneously maintaining the
temperature of the waste mixture at not less than 55 degrees C (131
degrees F) within 6-8 inches below the surface of the pile. In
turning the windrow, the exterior of the pile shall be turned into
the interior to ensure that all solid waste is exposed to composting
conditions.
b. Aerated static pile
composting method - The pile shall be insulated (e.g. using a 6-12"
layer of sawdust, wood chips, or cured compost) and a temperature of
not less than 55 degrees C (131 degrees F) must be maintained
throughout the compost pile for at least three consecutive days.
c. Enclosed vessel composting
- The mixture in the vessel shall be maintained at a temperature not
less than 55 degrees C (131 degrees F) throughout the mixture for at
least three consecutive days.
d. If other
Department-approved composting methods are employed, operating
practices shall reduce pathogens to the extent equivalent to the
reduction achieved in any of the above methods, and such operating
practices shall be approved by the Department.
6. Temperature Monitoring
a. Monitoring of the
temperature of the waste during the composting period must be
performed to ensure proper temperature ranges to destroy pathogens
and inactivate weed seeds as well as to maintain proper conditions
for microbial activity necessary for decomposition of the waste.
b. During the period when
conditions necessary to achieve PFRP are being maintained, the
following temperature monitoring requirements shall be employed
(during PFRP verification):
(1) Windrow composting -Daily
temperature readings shall be taken, at equally spaced intervals, for
at least (no greater than) every thirty feet of windrow length, but
in no case shall there be less than two sets of readings for each
windrow. Monitoring shall be at 6-8 inches and 18-24 inches below the
pile surface.
(2) Aerated static pile
composting - Daily temperature readings will be taken, at equally
spaced intervals for at least (no greater than) every 20 feet of pile
length, but in no case shall there be less than two sets of readings
for each pile. Monitoring shall be at 6-8 inches and 18-24 inches
from the outlet of the aeration pipe and at 6-8 inches, 18-24 inches
below the pile surface at locations that are not adjacent to an
aeration pipe.
(3) Enclosed Vessel Composting
- Daily temperature reading shall be taken, monitoring 6-8 inches and
18-24 inches inside the vessel wall and 6-8 inches from the aeration
piping when operating in the positive pressure mode. As an option
(due to variability of design among vessel options), the
temperature-monitoring plan shall be system specific and must prove
to the Department's satisfaction that it will be adequate to
determine if PFRP conditions are being met.
(4) Temperature readings shall
be taken in the same locations each day and an arithmetic average
shall be calculated for each day's readings.
c. Throughout the entire
composting process the temperatures of the waste being composted must
