Zephyr assisted a petrochemical client with a large greenfields development in Nueces County, Texas. A wetland determination identified waters of the US and several potential wetlands at the site. Upon consultation with the U.S. Army Corps of Engineers (USACE) and coordination with our client, impacts to the wetlands were calculated and indicated that an Individual Permit would be required. Zephyr performed a detailed delineation of impacts to wetlands and the waters of the US in preparation of the Individual Permit. This project has required consistent coordination with USACE and other regulatory agencies.
