Interoffice Communication To Plant Managers From J. D. Burns Data September 23, 1971 Subject Five-Year Plan for Environmental Projects We have completed most of the conceptual programs, design, engineering, and construction for most of our present environmental projects. Pending legislation in the areas of air and water pollution indicates additional abatement programs. Please develop a posslble/probable project list that you believe will be required during the next five years. As an example of some of the pending legislation, below is a list of the pollutants currently being scrutinized: (a) Toxic metals -- i.e., mercury and cadmium (b) Hydrocarbon emissions into the atmosphere (c) Sulfur dioxide (d) Nitrous oxides (e) Particulate matter (f) Chromates Xg) Heavily chlorinated hydrocarbons Since these items may be subject to further controls, we should have both recent data and a thorough understanding of current state and federal legislation relating to these items.
