Trade Offs

This paper reports an evaluation of the econometric model developed by Regional Econometric Models Inc. for the South Coast Air Quality Management District. The analysis is focused on the in-sample performance, forecasting ability, and characteristics in impact analysis of the model. The trade-offs implicit in the performance of this model relate directly to questions of explanatory power. In particular, the model is characterized by well-specified structural equations that enhance its ability to formulate policy-relevant simulations. This may come at the cost of predictive ability in a statistical sense. Choices related to this trade-off are at the heart of applied regional analysis.

Performance Results

A comprehensive field data collection campaign is reported on in which operational data are being obtained from microturbine generators located in the South Coast Air Quality Management District (AQMD). The data obtained are archived in a SQL database, which provides the ability to look at various performance aspects as a function of many parameters interactively on the Internet. An overview of the program is provided along with details regarding the data collection and archiving strategies. To provide a framework relative to optimal operation of these systems in the region, economics associated with various operational schedules as a function of various rate structures in Southern California are provided. In addition to quantitative operational characteristics and performance results, some general end-user impressions of the technology and of the overall installation process are also documented. Details from three representative sites are presented.

Many areas of the United States are working toward achieving the 2015 ozone National Ambient Air Quality Standard (NAAQS) attainment level. The objective of this study was to develop future-year (2030) volatile organic compounds and nitrogen oxides (VOC-NOx) isopleth diagrams of the 4th highest maximum daily 8-h average ozone design value concentrations at monitors of interest in the South Coast Air Basin (SoCAB) and San Joaquin Valley (SJV) in California, and in Maryland. The simulation results showed there would be attainment of the 2015 ozone NAAQS in 2030 without further controls at the selected monitors: 27% in SoCAB, 57% in SJV, and 100% in Maryland. The SoCAB ozone isopleths developed in this study were compared with those reported in the South Coast Air Quality Management District 2016 Air Quality Management Plan. There are several differences between the two modeling studies, the results are qualitatively similar for most of the monitors in the relative amounts of additional emission reductions needed to achieve the ozone NAAQS. The results of this study provide insight into designing potential control strategies for ozone attainment in future years for areas currently in non-attainment. Additional photochemical modeling using these strategies can then provide confirmation of the effectiveness of the controls.
