2007-12 TIP UPDATE
CMAQ PROGRAMMING DISCUSSION
PART ONE: BACKGROUND
Programming
Considerations
CDTC’s Transportation Improvement Program (TIP) update appears to provide Congestion Mitigation / Air Quality (CMAQ) funds for programming to new commitments. As with the decisions made for the 2005-10 TIP, three considerations are discussed below.
1. Existing CMAQ Program Balance
CDTC’s CMAQ emphasis on operations is very high, in contrast
to national practice. Approximately half
of CDTC’s CMAQ program is committed to
2. Draft TIP Balance and New Visions
Balance
A second reference point is the comparison of expenditures in the draft TIP against the budgets in the New Visions 2025 plan. CDTC typically uses this comparison as a starting point in “dedicating” the first round of programming to project categories that are under-funded in the TIP, relative to the plan.
Not surprisingly, the New Vision project category most under-funded in the TIP is pavement and bridge rehabilitation on the priority system. Recent work by the Transportation Finance Task Force and recent experience with high bid prices reinforce the conclusion that highway and bridge infrastructure needs face the biggest funding gaps. However, CMAQ is not an effective tool to fill that gap.
Of those project categories that can be helped by the available CMAQ balance, both ITS deployment / operations and “supplemental” bike and pedestrian actions (beyond those improvements made in the context of infrastructure rehab projects) are under-funded in the TIP, relative to the plan.
3. Air Quality Benefits
A third reference point for the CMAQ discussion is emission reductions. This aspect must be considered carefully. Nationwide, various studies have attempted and failed to document the absolute amount of emissions reductions achieved by the CMAQ program. The conclusion is that the CMAQ program is important to achieving air quality standards, but estimation methodologies and before-and-after measurement are too inconsistent from state to state to reach numeric results.
CDTC has long asserted that CMAQ makes a critical contribution to the achievement of clean air, despite the fact that vehicle technology will contribute to a far greater reduction in emissions over time than any combination of CMAQ projects can achieve. In CDTC’s case, the argument is that the overall New Visions plan – including regional and local land use planning and design; demand management; system management and technology; and strategic highway and transit projects will reduce future rates of vehicular travel and congestion from the “no build.” CMAQ funds a noticeable portion of some of these strategies (such as traffic operations) and complements many others (such as bike projects complementing land use strategies).
CDTC’s air quality conformity assessment indicates that Volatile Organic Compounds (VOC) have already dropped by 35% and Nitrous Oxide emissions by 20% from 1990 levels primarily due to vehicle technology. A further 77% reduction in VOC and 87% reduction in NOx is forecast by 2025. Financially-constrained implementation of CDTC’s New Visions plan will drop VOC another 17% and NOx another 10% from the no-build 2025 levels. CMAQ projects contribute a portion of that additional reduction.

Emissions reductions and cost-effectiveness in the CMAQ program were paramount in the Senate Environment and Public Works Committee language included in SAFETEA-LU to require states and MPOs to give “priority” to diesel retrofits in distributing CMAQ funds, and extend CMAQ eligibility to off-road retrofits. In 2002, FHWA stated in reference to off-road emissions:
The
emissions performance of off-highway mobile sources has been even more
troubling. For volatile organic compounds (VOC), on-road emissions were down 59
percent from 1970-1999, but non-road engines-many of which are
diesel-registered an increase of 72 percent over the period. While on-road
emissions of NOx increased a modest 16 percent during this same period, the
off-road inventory rose 186 percent. These increases pose significant challenges
for areas to reach their emissions reduction targets. In addition, much of this
fleet is at least indirectly linked to transportation programs, e.g. highway
construction vehicles, port handling equipment, and other off-road mobile
sources. Source: http://www.fhwa.dot.gov/environment/cmaqpgs/retrowhi.htm
On an emissions reduction efficiency basis, diesel retrofits appear to have merit.
Programming
Implications
The implications of the three considerations above are mixed. Given its starting point of a balanced TIP and a broad array of CMAQ commitments, CDTC could choose to emphasize one or two project categories or fund a number of initiatives and support the decision on the basis of air quality and the benefits of integrated transportation planning and operations. National practice, New Visions’ funding needs and air quality cost-effectiveness provide slightly different inferences.
PART TWO
Introduction
At its October 4, 2006 meeting, the CDTC
After review and comment, the Planning Committee will take action at its February meeting to reaffirm or revise this recommendation and incorporate it into the draft 2007-12 Transportation Improvement Program for consideration by the Policy Board.
The Recommended
Bundle
Alternative funding bundles were considered by the Planning Committee. Some emphasize operations, other have a heavy emphasis on transit vehicle replacement with cleaner engines. Another would put a great emphasis on intersection improvements such as roundabouts. An estimate of the maximum feasible commitment of CMAQ funds to the various categories summed to over $100 million; approximately $24 M is expected to be available to program.
Discussion at the November meeting led the Planning Committee to agree to a bundle that balances commitments of additional funds to operations, transit vehicle replacement and intersection (roundabout) improvements with modest additional funding to bike/pedestrian projects and a fleet / off-road diesel retrofit pilot effort. This last entry is a direct response to Congressional intent and language of SAFETEA-LU.
For public review and comment, the Planning Committee recommends that CDTC release the following bundle of categorical commitments with the intention that they be incorporated into the 2007-12 TIP.
