Operation at a permitted surface mine site necessitates a license. A single surface mine location may accommodate multiple licensees. Conversely, a license holder is authorized to operate across multiple permitted surface mine locations. It is important to note that the license grants operating authority but does not confer the right to extract materials from the site.

A permit is required for mineral extraction operations that will result in a land disturbance of one (1) acre or more. Minerals are defined as any substance of commercial value found in natural deposits on or in the earth. This includes, but is not limited to, clay, gravel, metallic ores, sand, soil, and stone. Coal is specifically excluded from this definition. Permits must be renewed every five (5) years and are subject to unlimited renewals.

Authorize activities that change the course, current or cross-section of waters of the State.

Authorize permanent and temporary impacts to nontidal wetlands and the nontidal wetland buffer.

A valid permit is required for any operator undertaking the extraction of oil or natural gas from the earth. This authorization specifically covers the production of oil or gas via a drilled well. It is important to note that, due to Maryland's enacted moratorium on hydraulic fracturing (hydrofracking), the State has not received any applications for new wells since the moratorium took effect.

This license is required to perform inspections of on-site wastewater disposal (septic) systems for the purpose of property transfers.

Property Transfer Inspection (PTI) ensures on-site sewage disposal systems are properly inspected during property transfers by individuals licensed by the Maryland Department of the Environment in accordance with COMAR 26.04.12. Licensed inspectors must complete Department-approved training, use the standard inspection form, maintain inspection records for five years, and comply with all regulatory requirements to protect public health and the environment.
