West Virginia Department of Environmental Protection to Update WV NPDES Multi-Sector General Permit No. WV0111457

The West Virginia Department of Environmental Protection (WVDEP) has proposed to update the West Virginia/National Pollutant Discharge Elimination System (WV NPDES) Multi-Sector Stormwater General Permit (MSGP) for Industrial Activities (Permit No. WV0111457) which will expire on September 12, 2024. The draft 2024 MSGP is available for review on the WVDEP MSGP Webpage; the public comment period has ended. The planned effective date for the 2024 MSGP is not yet known.

Proposed Changes to Permit No. WV0111457

Substantial changes to the existing permit include but are not limited to:

• Updating the total recoverable lead benchmark for Sector G-1
• Creating additional requirements for the stormwater pollution prevention plan (SWPPP) figure map
• Updating the reapplication timeline from 180 days to 30 days following reissuance of the general permit
• Standardizing the quarterly sampling period and reporting deadline to be the same for each permittee
• Stipulating new facilities applying for coverage under the 2024 MSGP to comply with the antidegradation requirements.

What Actions do you Need to Take?

If your facility has coverage under this permit, expect to submit a notice of intent (NOI) and an updated SWPPP via the Electronic Submission System (ESS) within 30 days of the effective date of the 2024 MSGP to ensure the facility’s stormwater coverage is uninterrupted. Facilities with a No Exposure Certification must resubmit within 30 days of the effective date of the 2024 MSGP as well.

If your facility is a new facility seeking coverage under this permit, prepare to comply with antidegradation requirements including public notice, implementing best management practices (BMPs) prior to stormwater discharge, and submitting a SWPPP and Groundwater Protection Plan with your NOI.
