PS05 TVA Fly Ash Spill Air Monitoring Station, Harriman, Tennessee

PS05 TVA Fly Ash Spill is an air monitoring station located at 1025 Swan Pond Road in Harriman, Roane County, Tennessee. Operated by the Tennessee Valley Authority (TVA), this station is part of the post-spill environmental monitoring network established after the 2008 Kingston Fossil Plant fly ash spill. The station plays a critical role in assessing air quality impacts from the spill site and ongoing remediation activities. As an air monitoring station, PS05 TVA Fly Ash Spill operates under the regulatory framework of the U.S. Environmental Protection Agency's (EPA) Ambient Air Quality Monitoring program. The station likely measures criteria pollutants such as particulate matter (PM10 and PM2.5) and may include speciation for metals and other contaminants associated with fly ash. Monitoring stations in this network typically follow EPA siting criteria to ensure representativeness of local air quality. The environmental significance of this station lies in its role in long-term monitoring of a major industrial spill site. Continuous air quality data helps protect public health and the environment by detecting any resuspension of contaminated dust. The station contributes to the broader understanding of air quality impacts from coal ash disposal sites and supports regulatory compliance and remediation effectiveness assessments.

The PS05 TVA Fly Ash Spill station is situated in the Tennessee Valley region, characterized by a humid subtropical climate with moderate air pollution potential from industrial sources. The station's primary focus is monitoring airborne particulate matter and metals from the fly ash spill site, which is a key environmental concern due to potential health risks from inhalation. The monitoring program aligns with EPA's National Ambient Air Quality Standards (NAAQS) for particulate matter and hazardous air pollutants. Siting representativeness is critical to capture fugitive dust emissions from the remediation area.
