Water Suppression

Dominion Terminal Water Application
While the sprinklers are not on at the moment of the photograph, large amounts of standing water are visible at the Dominion Terminal.

Coal dust emissions are primarily managed using wet suppression methods that consist of spraying water over coal storage piles, railcars, and transloading equipment using a system of sprinklers. Water application is often adjusted based on terminal activity and the ambient humidity conditions.

Water suppression is mentioned in the record as early as the 1920s, when the Chesapeake and Ohio (C&O) Railroad Company installed a custom pipe system to wet coal-filled railcars where and when the cars were emptied through overturning.[1] Following an air monitoring study in 1956 demonstrating coal was a major portion of airborne dust in Southeast Newport News and pressure from the Newport news City Council, C&O installed equipment to create a water fog over the coal piers to suppress dust.[2]
