AT&T has hired EBI directly to perform large portfolios of environmental and regulatory services, including National Environmental Policy Act (NEPA) services and Environmental Health and Safety (EH&S) services. EBI had on-site EH&S employees at AT&T for a number of years before the service was brought in-house. EBI continues to serve and consult on their in-house EH&S operations and practices.

In addition to being hired directly by AT&T, EBI Consulting has also been retained by General Dynamics (GD) Wireless services to conduct environmental health and safety (EH&S) services at AT&T generator sites. This portfolio consists of sites across 34 states, largely in the Midwest, for which EBI has been serving since 2016. To date, over 2,030 projects have been completed on this portfolio, comprised largely of air and tank assessments and permitting, as well as some SPCC services.
