NRSS - 18351 - NR-ARD-6 IMPROVE OPS & FILTER ANALYSIS

The Department of the Interior is forecasting a contract for the operation of the IMPROVE network and the analysis of particulate matter samples. This initiative is critical for assessing visibility conditions, identifying sources of haze, and tracking long-term trends within Class I areas, directly supporting the National Park Service's responsibilities under the Clean Air Act and the Regional Haze Program. The scope of work includes sampling, filter processing, and laboratory analysis. Because these monitoring records cannot be recreated, maintaining continuity is essential to avoid data gaps or backlogs. The project is categorized under NAICS code 541620 and is managed by the National Park Service.
