Maryland’s Revised General Permit for Stormwater Discharges from Industrial Activities

Latest News

This year the Maryland Department of the Environment (MDE) is renewing the General Permit for the discharge of stormwater from industrial activities. The new permit, No. 20-SW, applies to all facilities in Maryland covered under the old permit (No. 12-SW) along with certain other industrial facilities that discharge stormwater during rain or snow events. To be covered under the new permit,  applicants must complete a Notice of Intent (NOI) form, pay a fee, and submit a Stormwater Pollution Prevention Plan (SWPPP).

The renewed General Permit introduces some new requirements, including signage and a corrective action program whenever benchmark thresholds are exceeded. EEC Environmental has extensive experience in stormwater and wastewater permitting and compliance services for industrial clients in Maryland and throughout the United States. This includes coverage under general discharge permits, as well as obtaining facility-specific National Pollution Discharge Elimination System (NPDES) permits. EEC has successfully negotiated:

  • Industrial discharge permits to regional POTWs
  • Reduced sampling requirements for NPDES
  • Permit approval for unique situations
  • Reduced Individual permit requirements.

EEC’s engineers and scientists are familiar with all aspects of the stormwater regulatory process and permitting requirements. Our stormwater expertise has been applied to the design of treatment processes for both stormwater and industrial process wastewater to meet applicable regulatory requirements while minimizing facility disruption and expenses.
