A Notification of Intent (NOI) must be submitted for construction sites that disturb what minimum area?

The requirement for submitting a Notification of Intent (NOI) is tied to the area of land disturbance associated with construction activities. Specifically, in Maryland, a NOI must be submitted for construction sites that disturb a minimum area of 1 acre or more. This regulation is in place to ensure that adequate erosion and sediment control measures are implemented to protect water quality and manage stormwater runoff effectively.

When construction activities disturb 1 acre or more, they can significantly contribute to soil erosion and sedimentation in nearby waterways. By requiring an NOI for these sites, the state mandates that developers and builders take responsibility for minimizing such environmental impacts. The submission of the NOI also triggers additional requirements for the preparation and implementation of a Stormwater Pollution Prevention Plan (SWPPP), which outlines measures to control erosion and manage stormwater runoff throughout the construction process.

Understanding this threshold is crucial for ensuring compliance with local regulations and for the protection of Maryland's natural resources.
