This document is a Maryland Department of the Environment Letter of Authorization for a culvert replacement project at the Centers for Medicare and Medicaid Services headquarters in Baltimore County, Maryland. The authorization (Number 15-NT-0373/20156138) is valid from June 21, 2016 to June 21, 2019, and permits the replacement of four existing 41-inch x 64-inch corrugated metal pipes with a new concrete box culvert. The project will result in permanent impacts to 580 square feet of forested nontidal wetlands, 385 square feet of emergent nontidal wetlands, 105 square feet of 25-foot buffer, and 1,365 square feet of temporary nontidal wetland impacts. The work is located at 7500 Security Boulevard and will involve stream and wetland restoration, with specific best management practices required to minimize environmental disruption, including erosion control, vegetation stabilization, and careful management of construction activities.
