EROS Visitor Safety and Security
The EROS Director’s Office and Facilities Management are dedicated to providing a safe and secure environment for visitors to our facility. The following information is intended to inform EROS visitors of the safety and security requirements to better insure that everyone has a safe and secure visit.
All public visitors’ vehicles and persons will need to be screened prior to being allowed access onto Federal property. All visitors are required to stop at the main gate where you will receive additional instructions. A parking pass will be issued and you will be directed to the Visitor parking lot.
Upon entrance to the visitor main lobby, you will be processed through a security check point. Only bring in items that are necessary. Cameras and video recorders are allowed inside the facility with some restrictions. Taking pictures outside the Center is not authorized without permission. Animals are not allowed on Federal property unless they are documented working animals with a valid license or certification to do so.
USGS requires all visitors to present government-issued identification for access to its facilities. Visitors age 16 or older will be required to present valid government-issued photo identification (federal, state, or local), such as a driver's license that is REAL ID compliant, an enhanced driver’s license, or a passport. Visitors under 16 years of age must be accompanied by an adult (parent, sponsor, or guardian) that can verify identities. All public visitors driving a vehicle must have a valid REAL ID compliant or enhanced driver’s license.
Currently, the following jurisdictions do NOT meet the REAL ID standards: Kentucky, Maine, Minnesota, Missouri, Montana, Pennsylvania, and Washington. If you have a driver’s license or identification card issued by a state that does not meet the requirements of the REAL ID Act, unless that state has been granted an extension, you must present an alternative form of identification, such as a passport or Federal employee, military, or veteran ID, to facilitate access. As this list is subject to change, please check for the most up-to-date information at https://www.dhs.gov/secure-drivers-licenses.
