What is the maximum amount of disturbed area allowed at any site without special authorization?

The maximum amount of disturbed area allowed at any site without special authorization is 30 acres. This regulation is established to ensure proper management of erosion and sediment control on construction sites. By limiting the disturbed area to 30 acres, it is easier to implement effective sediment control measures, monitor compliance, and reduce the risk of environmental impact caused by sediment runoff.

If a project site exceeds this threshold, special authorization becomes necessary, which typically involves more stringent oversight and requirements to prevent erosion and protect water quality. Understanding this limit is essential for compliance with Maryland's environmental regulations and helps maintain the integrity of local ecosystems during development activities.
