W. J. Petersen to Carl Schulz on Dust Exhaust at No Agua and Antonito (1960)

A one-page memo of February 15, 1960, from W. J. Petersen to Carl Schulz at Joliet, copied to J. C. Kingsbury and H. M. Jackson, headed "Effect of Dust Exhaust on Surrounding Property, No Agua and Antonito." Petersen reports that the Travelers Insurance Company had told J-M's insurance people that unless dust collection equipment was installed at both the No Agua mill and the Antonito operation, Travelers would not give the same coverage "against damage to surrounding property" that J-M had at its other plants. He asks Schulz how far windblown dust from the two sites might reach, who owned the land within that area, and whether any homes or part of the town of Antonito lay inside it.

In Johns-Manville's chronology

Johns-Manville's own chronology of what the company knew describes this document as follows:

On 2/15/60, W.J. Petersen (Manville) advises C. Schuls (Joliet) that due to the dust exhaust on surrounding property at No Agua and Antonito, Travelers has advised J-M that unless dust collection equipment is installed at both the mill and Antonito operations, Travelers will not extend the same coverage against damage to surrounding property as they do at other J-M plant locations. Peterson asks Schulz to determine the area which might be affected by windblown dust and also to determine ownership of the property (in particular, make a list of any residences which are located within that area).
