Industry Seeks EPA-Led Modeling 'Summit' To Resolve NAAQS Concerns

摘要

Industry lawyers are pushing Epa to convene a "summit" of air quality modelers and other experts with the goal of addressing long-running concerns about the agency's increasing reliance on modeling over monitoring to determine compliance with its air standards, an approach critics say could overestimate non-compliance problems. Industry officials argue that the concerns over modeling are causing a freeze on Clean Air Act permit applica tions because the models make it difficult for companies to show facilities seeking air permits would not violate agency air standards, while states say the agency's models have flaws and that increased modeling use drains resources.
