Why Public Works Requires This

Municipal facilities face simultaneous NPDES MS4, CA IGP, FOIA, and Davis-Bacon requirements — with public accountability at every step.

🌊

NPDES MS4 Zero-Discharge

San Diego Region MS4 Permit CAS000002 mandates zero process water discharge to storm drains at industrial facilities. Without a certified PAR on file, a single inspector visit can trigger an NOV and fine.

💧

CA IGP 100% Recovery

Industrial General Permit CAS000001 requires documented 100% water capture for covered facilities. The SumpVac recovery record + disposal manifest is the only proof of compliance if SWRCB audits the facility.

📂

FOIA-Ready Documentation

Public records requests for municipal facilities happen regularly. A PAR provides a self-contained, inspector-ready record that satisfies CPRA requests without scrambling for phone photos and handwritten notes.
