Assessments
Action
Scenarios
The conformity assessment depicts the results of the Action
Scenarios testing versus the budgets established for each emission level for the
analysis years. To develop the
action scenarios, the base year highway network, the highway system as it
existed in the model in the year 2000, is used as the starting point.
For each analysis year, the highway network is modified based on the
projects to be analyzed, as identified in Attachment 1.
For each analysis year, the SJTDM is re-run with the appropriate future
year demographic inputs and the modified, “action” highway network assumed
in place by the analysis year. The
corresponding emissions generated are a result of both the future year
demographic inputs and the new projects, or actions, added to the base network
in the appropriate year. The
emissions from these “action” scenarios are then compared to the
corresponding analysis year emission budgets
Plan Conformity Determination
As all tests passed for all required years, and all related requirements were
met as reviewed above, the Regional Transportation Plan complies with federal
Clean Air regulations and is a conforming plan.
Budget
Tests
As was previously stated, SJTPO regional budgets anticipated under
the proposed Rate of Progress Plan are used for VOC and NOX.
Budgets for the analysis years for VOC and NOX, previously stated as
2002, 2005, 2015 and 2025, are listed below.
CO budgets under the maintenance plan are evaluated at the county level
to account for Atlantic City and part of Penns Grove.
CO budgets are also listed below for years 2002, 2005, 2007, 2015 and
2025.
Budget tests were performed for VOC and NOX for the SJTPO region.
The tests show whether improvement actions, or the action scenarios, keep
emissions within budget. Results
are determined by subtracting projected emissions from the budgeted amounts.
The VOC and NOX budget tests for analysis years 2002, 2005, 2015 and 2025
all passed, as seen in the Tables 7-4 and 7-5 below.
