PCR's Air Quality scientists and engineers, with advanced degrees and professional registrations, are recognized experts in their fields. Since passage of the original Clean Air Act the regulatory landscape has intensified. New designations and conflicting regulations are continually being created or revised. We take pride in up-to-date and in-depth understanding of the complex and evolving regulatory landscape facing industrial facilities, development proponents, and governmental planners. Project applicants face changing regulations and increasing opposition and litigation risks. Many manufacturing firms will spend a majority of their environmental budget on air quality compliance. As a result, air quality impact analyses must withstand challenges from diverse stakeholders. PCR's best-in-class Air Quality Services Division has the personnel, resources, and reputation to deliver solutions which are scientifically sound, creative and legally defensible. PCR's Air Quality Services Division understands that achieving compliance is delivering value.
