Water Suppression
Coal dust emissions in Southeast Newport News and Lambert's Point are primarily managed using wet suppression methods that consist of spraying water, or water with chemical additives, over coal storage piles, railcars, and/or transloading equipment using a system of sprinklers. Water application is often adjusted based on terminal activity and 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 spray water on 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]
Today, the coal export terminals continue to rely on water suppression despite community calls for other forms of dust mitigation, particularly a wind fence or dome in Southeast Newport News or railcar coverings in Lambert's Point. The Kinder Morgan Bulk Terminals use a system of 44 sprinklers to spray water that suppresses dust emissions from the piles and transloading equipment.
Water suppression is argued to be effective at fairly low cost,[3] and the terminals in Southeast Newport News and Lambert's Point have fought against other dust mitigation methods because of their associated costs.[4] Despite decades of dust control using water suppression, nearby residents continue to report evidence that coal dust affects local air quality, outside and in their homes.
