General Discharge Permit For Discharges Associated with Construction Activities

Maryland General Permit No. 20-CP

On September 25, 2020, the Department published notice of its tentative determination to renew the current general discharge permit (14GP) for stormwater associated with construction activities and replace it with proposed General Discharge Permit No. 20CP (NPDES No. MDRC). The proposed permit applies to stormwater discharges from construction activities in the state of Maryland that will disturb one or more acres of land, or will disturb less than one acre of land but are part of a common plan of development or sale that will ultimately disturb one or more acres of land. The Department held a public hearing regarding the tentative determination on November 10, 2020. Notice of the hearing was included in those publications.  The public comment period concluded on December 24, 2020.  

The Department is preparing a final permit determination and is now informally seeking comments limited to these four areas: addressing climate change, timeframes related to gaining authorization, threatened and endangered species, and water quality-based limits. Further background and details on these proposed changes from the tentative determination may be found on the Department's website at: https://mdewwp.page.link/CGP.

Written comments concerning these potential changes may be considered in the preparation of a final determination. You may send your comments to  Paul Hlavinka at paul.hlavinka@maryland.gov, by mail to Maryland Department of the Environment, 1800 Washington Blvd., Suite 455, Baltimore, MD  21230-1708, or by (fax) 410-537-3163, by close of business on or before Monday, September 12, 2022.
