Low-level overflights and sonic booms have been suspected of having serious effects on domestic fowl. Some of these
effects have not been produced experimentally, despite repeated attempts. Panic effects such as piling and crowding have been
the focus of several recent studies, but they did not determine the threshold for this response, The present program included
experiments on two cohorts of naive broilers, young (3 weeks) and older (8 weeks), and Cobb white-leghorn laying hens. Poult
weight gain and carcass quality were also examined in birds exposed during this study. The program collected heart rate
measurements of young broilers during and after exposure to a series of simulated overflights in an effort to obtain a
physiological estimator of broiler response to overflight stimuli. The broilers were exposed to simulated overflights that varied
in sound exposure level, onset time, duration and interval between exposures. Such measurements had not been made in
poultry prior to these experiments. Hens and broilers did not experience excess mortality or changes in weight as a result of
exposure. Egg production was not affected by simulated overflights, nor was egg quality.

Ends of Uncertainty: Air Quality Science and Planning in Central California
Fine, J.; Sep. 2003; In English
Report No.(s): DE2004-822267; No Copyright; Avail: National Technical Information Service (NTIS)
This report is based on a dissertation by James Fine, The Ends of Uncertainty: Air Quality Science and Planning in Central
California, which was filed with the University of California at Berkeley Energy and Resources Group on May 23, 2003. The
research involved two primary tasks: 1. Description and critique of the uses of simulation models and the management of
uncertainties in modeling in air quality planning. This task was completed using a case study of Central California in the
1990s. In addition to description and critique, the research produced prescriptions for modifying the planning process to allow
for the development and incorporation of uncertainty information, as well as the meaningful participation of all stakeholder
groups. 2. Review of photochemical air quality simulation model uncertainties and uncertainty analysis capabilities to examine
what model uncertainty information can and should be produced to assist air quality planners.

Maryland Utility NO( x) Control Update Report
Salman, A. S.; Ross, J.; Joshi, S.; Jun. 2004; In English
Report No.(s): PB2004-105855; No Copyright; Avail: National Technical Information Service (NTIS)
This report is the result of a project funded by the Maryland Power Plant Research Program to update information on the
status of installed Nitrogen Oxide NO(x) emission controls at fossil fuel-fired (coal, oil, and natural gas) power plants
operating in Maryland. The goal of this project was to identify NO(x) controls installed or upgraded since PPRP’s original
Maryland Utility NO(x) RACT Update Report was developed in 1999, as well as to identify new power plants and their
controls built in Maryland since that report. A further goal was to obtain information about NO-x emissions and controls for
gas turbine based oil and gas-fired simple and combined cycle power plants operating or under construction in the State. This
report also identifies new NO(x) control technologies that are available for potential use in power plants in Maryland, as well
as upcoming technologies that may become available in the near future.
