Monitoring Checklist	
Subpart TT, Greenhouse Gas Reporting Program
What Must Be Monitored for Each Landfill that Meets the Requirements of 98.460 and
Each industrial waste landfill must monitor these parameters...
United States
Environmental Protection
Annual quantity of each waste stream
disposed of in the landfill
(Wx in Equation TT-1)
For each type of cover material (either
organic cover, clay cover, sand cover, or
other soil mixtures), determine the
surface area (in square meters) at the
start of the reporting year for the landfill
sections that contain waste.
For each waste stream for which you
elect not to use the default DOC values
in Table TT-1 of subpart TT,
determine the DOC value by either
using a 60-day anaerobic
biodegradation test or via the total and
volatile solids measurements following
Standard Method 2540G "Total, Fixed,
and Volatile Solids in Solid and
Semisolid Samples"
Each industrial waste landfill using a gas collection system
	must also monitor these parameters...	
Flow rate (or cumulative volume) of
landfill gas collected before any
treatment equipment (daily)
CFU concentration of collected landfill
gas (daily, if available, or weekly)
Temperature of landfill gas (daily, if
available, or weekly)
Pressure of landfill gas
(daily, if available, or weekly)
Moisture content of landfill gas (daily, if
available, or weekly)
Operating hours for each destruction
~ device (and back-up destruction
device, if applicable)
Annual operating hours of the gas
collection system associated with each
measurement location
Gas collection system operating hours
per year
The number of wells of the gas
collection system
Surface area, average depth of waste,
and associated estimated collection
efficiencies of areas with the different
soil type covers and gas collection
system operation listed in Table HH-3
