Title: VALMET: a valley air pollution model. Final report. Revision 1

Abstract

An air quality model is described for predicting air pollution concentrations in deep mountain valleys arising from nocturnal down-valley transport and diffusion of an elevated pollutant plume, and the fumigation of the plume on the valley floor and sidewalls after sunrise. Included is a technical description of the model, a discussion of the model's applications, the required model inputs, sample calculations and model outputs, and a full listing of the FORTRAN computer program. 55 refs., 27 figs., 6 tabs.

  • Following a thorough analysis of meteorological data obtained from deep valleys of western Colorado, a modular air-pollution model has been developed to simulate the transport and diffusion of pollutants released from an elevated point source in a well-defined mountain valley during the nighttime and morning transition periods. This initial version of the model, named VALMET, operates on a valley cross section at an arbitrary distance down-valley from a continuous point source. The model has been constructed to include parameterizations of the major physical processes that act to disperse pollution during these time periods. The model has not been fully evaluated.more » Further testing, evaluations, and development of the model are needed. Priorities for further development and testing are provided.« less
  • The study quantifies the economic value of ozone and sulfur dioxide induced agricultural losses in the San Joaquin Valley of California. In 1978, the economic impact of air pollution on crops in the San Joaquin Valley was estimated to exceed $117 million (in 1978 dollars). Over 98 percent of these losses are attributed to ozone. The economic losses from exceeding the California hourly ozone standard of 10 pphm were $106 million. These estimates are thought to be lower bounds on the economic damages from air pollution, because conservative assumptions and methods were used throughout this analysis.
  • The objectives of this study were: (1) to determine whether sugar beets are being damaged by current levels of ozone, (2) to establish several points on the ozone dose response curve for sugar beets and (3) to compare the performance of open top growth chambers with conventional closed top greenhouse type chambers. Sugar beets were grown at Parlier, CA in chambers supplied with air containing varying proportions of existing pollutants achieved by filtering all, none or part of the air with activated carbon. Two types of chambers were used in the study, one a conventional greenhouse with plastic covered sidesmore » and top, and a second experimental unit with plastic walls and open top. Both types covered an area 12 feet square and were ventilated with continuously running motor driven blowers. The conclusion was that sugar beets are not now being significantly damaged by prevailing oxidant air pollution in the central San Joaquin Valley.« less
  • The environmental, social, economic and institutional impacts of the Federal Water Pollution Control Act Amendments of 1972 (P.L. 92-500) on the San Francisco Bay/Central Valley are reviewed. Point source programs will result in a high level of effluent discharge with minimal adverse environmental and economic impacts, and positive benefits in improved fishery and water recreation uses, and conservation of water supplies. The water pollution control effort in the study area is directly related to water quantity. Among the problems remaining are control of agricultural wastewater and urban runoff. Estimated capital costs (in 1973 dollars) of industrial waste treatment to achievemore » the 1977 requirement of best practicable treatment technology and the 1983 goal of best available technology will be $41.1 million and $91.8 million respectively O and M will be $5.2 million for 1977 and $14.6 million for 1983.

  • ORSANCO (Ohio River Valley Sanitation Commission) is an interstate agency. The study analyzes and recommends prospective roles that this agency can best perform which would be complementary to or in lieu of activities for which the member States of the federal government is responsible in controlling and abating water pollution in the Ohio River drainage basin.
