Legal Authority

What laws and regulations give Maryland Department of Environment the legal authority to issue this approval?

MDE does not issue the CPCN. Rather, the Public Service Commission (under the authority of Public Utility Companies Article, §§2-121 and 7-205 - 7-208 of the Annotated Code of Maryland) issues a CPCN. The CPCN incorporates Maryland’s pre-construction air permitting requirements, including non-attainment 1.03 New Source Review, 1.04 Prevention of Significant Deterioration (PSD) and other air quality regulations, as applicable. Once a facility is constructed, any additional permits such as a 1.05 State Permit to Operate or a federal 1.06. Part 70 Operating Permit are issued by MDE. The CPCN may also replace the 3.15 Water Appropriation and Use Permit.
