The preliminary inventory of hazmat flows, resulting from the baseline review, allows the project team to scope additional efforts for collection of data from all relevant external existing and new data sources, and focus on routes where • There is reason to believe risks are high, • Knowledge is limited or undocumented, • Potential exposures are extreme, or • Some combination of these elements is present. Collect and Review Existing HMCFS Data After reviewing the baseline information and scoping the data collection effort, the project team collects and reviews relevant existing data from all applicable sources.

During and after collecting existing data, the project team compiles and reviews the data to confirm that any new data collection efforts are needed and appropriately focused due to gaps in the existing data. Collect and Validate New HMCFS Data The project team may collect new data specifically for the HMCFS.

However, it shows that the complexity of conducting an HMCFS project generally increases as • Size of community increases, resulting in more diverse goods consumption; • Proximity to major hazmat producers, processors, and consumers increases; • Complexity of the local and regional economy increases, resulting in greater seasonal variations in hazmat transport for different sectors; • Precision required to support HMCFS objectives increases, increasing the need for locally relevant, specific hazmat transport data; • Number of different modes included in the HMCFS increases; • Number of major roadway transport corridors or segments included in the HMCFS increases; or • Availability of locally relevant existing data decreases, increasing the requirement for the collection of new data. The following two general HMCFS practices can be recommended for all LEPCs: 1.

– Plan for follow-on efforts to evaluate hazmat transportation in the community. Jurisdictions are able to identify changes in hazmat transportation patterns by referencing previous studies.
