Identification of waste types within those groups, e.g. for SQGs, use only RCRA requirements or include used oil.
An estimate of the state’s universe size for each group.
The data source that would be used, i.e., state would collect new data or use existing data or a combination.
Timeframe for data collection.
Other data quality issues (including those identified in the work assignment).
Any major program changes in the last few years for those groups, e.g. regulatory changes.
Whether there was agency support for measurement of the group.
See Appendix F for data quality considerations when selecting groups.
2.3 FINALIZING THE GROUP AND INDICATOR DEFINITIONS
On March 13, 2007, the States Common Measures Project held a workshop on finalizing group and indicator definitions for the small quantity generator sector and the auto body sector.
Note: Because of time constraints, states selected draft indicators for the SQG sector only. Work on the auto body sector was deferred to a later date. See Section 5 for Auto Body Sector.
2.3.1 Common Definition for Small Quantity Generators of Hazardous Waste
The project states evaluated similarities and differences in individual state definitions of SQGs. This evaluation included comparing generation rates, accumulation quantity limits and accumulation time limits across states. States decided to define SQGs for purposes of the project using the federal RCRA generation rate [any generator that generates between 100 kg/mo and 1000 kg/mo] and by the federal RCRA waste types [excludes PCBs and waste oil generators].
Once the SQG universe definition was established, states began to develop a set of performance indicators. In cases where a project state had a different accumulation quantity limit and/or accumulation time limit, it was agreed that state would use its own accumulation standard.
Below is a chart that highlights differences in the project state’s SQG accumulation quantity limit and accumulation time limit:
