8 Overall Conclusions and Recommendations The committee considered a number of analytic approaches to evaluate the effects of the New Source Review (NSR) rule changes.

20 NEW SOURCE REVIEW FOR STATIONARY SOURCES OF AIR POLLUTION be more formally elicited, through Delphi approaches, other types of formal expert elicitation protocols, and other processes that could take qualitative insights from area experts and translate them into useful information for quantitative analysis. If such information is not collected in a formal way on a representative population, it cannot be used as a basis for answering the questions in the committee's charge.

OVERALL CONCLUSIONS AND RECOMMENDATIONS 21 respond to rapidly changing business conditions. The committee considers this use of econometric methods to be a promising analytic approach, and the requisite data collection should commence as soon as possible, as described in the recommendations presented later in this chapter.

22 NEW SOURCE REVIEW FOR STATIONARY SOURCES OF AIR POLLUTION with appropriate geographic and temporal specificity (that is, to capture the transport and fate of emissions from a specific facility at an averaging time relevant for assessing health outcomes)

From page 253... ...
OVERALL CONCLUSIONS AND RECOMMENDATIONS 23 carbon monoxide (CO) -- and exposures to the pollutants and their health effects; the effects on electricity-generating facilities and other industrial sectors; and the effects on pollution-control technology and facility efficiency.

From page 254... ...
24 NEW SOURCE REVIEW FOR STATIONARY SOURCES OF AIR POLLUTION insufficient for estimating local changes in emissions that could affect public health. At best, IPM is a tool for assessing effects of national, or perhaps regional, patterns of emissions, which certainly are important to public health but can hide substantial local variations in effects.

OVERALL CONCLUSIONS AND RECOMMENDATIONS 2 Amendments, and the NOx state implementation plan (SIP) call of 1998)

From page 256... ...
26 NEW SOURCE REVIEW FOR STATIONARY SOURCES OF AIR POLLUTION expected to cause a relative increase (perhaps substantial) in emissions from the electricity-generating sector compared with the prerevison NSR case (see Chapter 6)

From page 257... ...
OVERALL CONCLUSIONS AND RECOMMENDATIONS 2 and making the cap national in scope. (NSR has local objectives as well, as mentioned in Chapter 2, so this comparison, which is limited to national emission reduction, should not be taken as attempting an overall assessment of NSR.)

28 NEW SOURCE REVIEW FOR STATIONARY SOURCES OF AIR POLLUTION in magnitude)

From page 259... ...
OVERALL CONCLUSIONS AND RECOMMENDATIONS 2 pected to contribute most to emissions and air-quality changes as a result of the NSR rule changes. For example, for NOx emissions, the cement industry and pulp and paper mills formed a large fraction of recent NOx permitting activity for modifications and permitted emissions.

From page 260... ...
260 NEW SOURCE REVIEW FOR STATIONARY SOURCES OF AIR POLLUTION readily distinguish between new sources and modifications, and the availability of the data varies by state. State permit data are generally limited and are often kept in paper form, with no attempt to be compatible with other states' databases, and there is not much information on minor-construction permits.
|
From page 261... ...
OVERALL CONCLUSIONS AND RECOMMENDATIONS 261 more informed updating of the model. Such an investment of effort may not be warranted only to understand the effects of the NSR rule changes, but development of a better working model of the effect of regulations on plant-level decision making would help to inform numerous future analyses.
