Emissions inventories for the eastern United States indicate that Maryland is responsible for only 2 to 3% of the total emissions in the five-state area encompassing Maryland. For nitrogen, anthropogenic emissions in Maryland account for 11% of those in the five-state region. Two circumstances suggest that the bulk of the deposited sulfate is produced outside Maryland: 1) easterly transport winds in Maryland are relatively infrequent; 2) elevated sulfate concentrations in rain observed at Deep Creek are frequently associated with winds from the northwest. A review of the evidence indicates that on the average, local and deposition due to isolated power plants will increase sulfate and hydrogen ion deposition by no more than 10% annually within a 30-km radius of the plant (equivalent to a pH depression of 0.1 unit). However, locally greater deposition may occur at specific locations that are frequently impacted by rain traversing the plume.
