53. Economic and Social Benefits of Visibility Improvements Over $130b per year in recreational spending. (Much of it at or near recreational sites) Improved visibility effects tourist preferences and travel expenditures. Non-valued benefits are significant. ($327m for ME; $6m for NH; and $600k to VT, Abt, 2000) Over $1.3b in health-care cost related benefits result from BART reductions in West.

54. Regional Haze and Visibility in the Northeast and Mid-Atlantic Linkages with other Air Quality Programs Haze particles = PM 2.5 (increased morbidity, mortality, respiratory and cardiac disease, etc…) Sulfates and Nitrates = Acid Deposition (decreased ANC, increase N Saturation, decreased pH) Nitrates  Eutrophication (deposited nitrate feeds algal blooms, depletes O 2, destroys marine ecosystem in bays and estuaries) VOCs, NO X  Ozone
