National Acid Precipitation Assessment Program, Version 2 (NAPAP)
Entry ID: EPA0141

Abstract: The "National Acid Precipitation Assessment Program, Version 2
(NAPAP)" was initiated under the Acid Precipitation Act of 1980
to study the causes and potential effects of acid deposition in
and around the United States. A fundamental objective of the
NAPAP research program was to investigate emissions sources that
may contribute to acid deposition. To achieve this role, a
NAPAP Task Group on Emissions and Controls developed historical
and current (1985) inventories of acid deposition precursor
