DATA COLLECTION METHOD AND SOURCES
For each flow, check the appropriate box that describes the data sources. Provide additional descriptions as needed.
Materials Energy Solid Waste Emissions
Direct measurement ' '
Company purchasing/utility records
Calculated from equipment specs
Engineering estimates
Permit limit
Other
Has extrapolation or allocation been used during data collection? If so, in what way?

Figure 3.4 Data collection form.

Examples of data collection sheets [2]. Key information that must be gathered
and documented include:

Reporting basis, time period, geographic location, and other use-
ful information for characterizing the process or reporting facility,
such as its age, share of total company or industry production, etc.
Types and quantities of material inputs
Incoming transportation of material inputs (reported by transpor-
tation mode and distance)
