Does this proposed permit apply to my facility?

The EPA MSGP applies only in states where EPA is the permitting authority, but many states copy this permit as a model. Electronics facilities should review the proposal, especially if their state may adopt similar requirements.

What are the biggest changes in the proposed MSGP?

Two major changes are the new stormwater control checklists in Appendix Q and the introduction of quarterly chemical monitoring for pH, TSS and COD. Sector AC (electronics) has never had required chemical monitoring before.

Why does the quarterly monitoring requirement matter?

Monitoring exceedances could trigger additional response actions. In some cases, even one exceedance could lead to costly corrective action or new compliance obligations for the facility.

How does Appendix Q affect electronics manufacturers?

Appendix Q introduces stormwater control measure checklists that may impose new expectations. IPC is seeking industry feedback to ensure they are appropriate for electronics operations.

What is IPC asking members to do?

IPC is asking facilities to review the proposed changes and report whether the requirements apply to them. Member feedback will guide IPC’s formal comments to EPA before the May 31 deadline.
