Led by Chris Herin, the Geosyntec project team recognized that soil excavation was too disruptive to site…
In the early decades of Clean Air Act implementation, it was common for permitting agencies to require facilities seeking Prevention of Significant Deterioration (PSD) permits to conduct pre-construction ambient air quality monitoring prior to permit issuance.
