IGF::OT::IGF THE CONTRACTOR WILL SEARCH AVAILABLE DATABASES AND WEBSITES AND SUMMARIZE PARK-SPECIFIC DATA RELATED TO AIR POLLUTION EFFECTS FROM OZONE (VEGETATION INJURY), SULFUR DEPOSITION (SOIL AND WATER ACIDIFICATION), AND NITROGEN DEPOSITION (ACIDIFICATION AND NUTRIENT EUTROPHICATION TO SOILS, VEGETATION, AND WATERS) IN THE 10 PARKS LISTED ABOVE. IN THE RISK ASSESSMENTS AT HTTP://WWW.NATURE.NPS.GOV/AIR/PERMITS/ARIS/NETWORKS/INDEX.CFM, EACH PARK WAS ASSIGNED A RATING RANGING FROM LOW TO HIGH FOR RISK FROM AIR POLLUTANT STRESSORS. IN ORDER TO EVALUATE THE APPLICABILITY OF THOSE RISK RATINGS, THE CONTRACTOR WILL COMPARE THE RISK RANKINGS TO DOCUMENTED ECOSYSTEM IMPACTS. FOR EXAMPLE, SHENANDOAH NATIONAL PARK IS RATED AT VERY HIGH RISK TO ACIDIFICATION FROM NITROGEN AND SULFUR DEPOSITION. THE CONTRACTOR WILL EXAMINE AVAILABLE WATER QUALITY INFORMATION TO ASCERTAIN WHETHER STREAMS AT SHENANDOAH HAVE BEEN, OR ARE LIKELY TO BE, ACIDIFIED. DATA WILL BE DISCUSSED IN A WRITTEN REPORT AND CONDITIONS OF RESOURCES (E.G., WATER AND SOIL QUALITY, VEGETATION HEALTH AND DIVERSITY) EVALUATED WITH RESPECT TO EFFECTS THRESHOLDS FOR THOSE RESOURCES (E.G., CRITICAL LOADS). CONTRACTOR WILL SUBMIT A DRAFT REPORT TO NPS FOR REVIEW. CONTRACTOR WILL ADDRESS ALL COMMENTS AND PROVIDE RECONCILIATION OF COMMENTS TO NPS, AND SUBMIT FINAL REPORT 16 WEEKS AFTER AWARD. DELIVERABLES DATABASE CONTAINING RESOURCE DATA RELEVANT TO AIR POLLUTION EFFECTS AT THE 10 PARKS (ACADIA, GREAT SMOKY MOUNTAINS, SHENANDOAH, GRAND TETON, VOYAGEURS, OLYMPIC, YOSEMITE, NORTH CASCADES, MOUNT RAINIER NATIONAL PARKS, AND THEODORE ROOSEVELT NATIONAL PARKS); DATA SHOULD FOLLOW NPS GUIDELINES AT HTTP://SCIENCE.NATURE.NPS.GOV/IM/DATAMGMT/INDEX.CFM. DRAFT REPORT FOR NPS REVIEW SUMMARIZING RESULTS AND DISCUSSING RESULTS WITH RESPECT TO RESOURCE CONDITION (E.G., CRITICAL LOADS) AT THE 10 PARKS; RESULTS SHOULD BE SUMMARIZED IN APPROXIMATELY 4-6 PAGES FOR EACH PARK; FORMAT SHOULD BE CONSISTENT WITH NPS GUIDELINES AT HTTP://WWW.NATURE.NPS.GOV/PUBLICATIONS/NRPM/HINTS.CFM. FINAL REPORT INCORPORATING RECONCILED NPS COMMENTS AND SUGGESTIONS IN FORMAT CONSISTENT WITH NPS GUIDELINES AT HTTP://WWW.NATURE.NPS.GOV/PUBLICATIONS/NRPM/HINTS.CFM.
