Why MWRD Standards Are Stricter Than EPA
Common Misconception: "If I'm EPA-compliant, I'm MWRD-compliant"
Reality: MWRD sets local discharge limits that are often more stringent than federal EPA requirements.
Many industrial facilities pass EPA testing but violate MWRD limits and they don't find out until an inspector shows up.
Are MWRD Standards Are Stricter Than EPA?
How MWRD Limits Differ From EPA
-
MWRD Local Limits are stricter on metals, organics, and other pollutants than EPA minimums
-
Categorical Pretreatment Standards (40 CFR Part 403) apply to specific industry types, and MWRD enforces them aggressively
-
SIU Classification triggers additional reporting and monitoring requirements that EPA doesn't mandate
-
Bypass & Slug Discharge Prohibitions are enforced with zero tolerance in the MWRD district
-
What This Means for Your Facility: If you're discharging without MWRD guidance, you're likely exceeding local limits without knowing it. Eagle audits your discharge data against actual MWRD local limits

Data Integrity You Can Prove
Are You Overdue? Checklist:
MWRD typically re-inspects SIU facilities every 2–3 years.
If your facility:
-
Has never been inspected
-
Was last inspected 3+ years ago
-
Has recent changes to processes or discharge
-
Is uncertain about compliance status
...you're likely overdue or a high-priority target.
Why This Matters Before MWRD Shows Up:
Is Your Facility Overdue for a Pre-Inspection Audit?
What a Pre-Inspection Audit Covers:
-
Full compliance gap assessment against MWRD local limits
-
Documentation readiness review (RD-115, RD-920, RD-925, calibration records)
-
Sampling protocol verification and lab certification check
-
Flow calculation validation (most critical area)
-
Report accuracy review and data QA
-
Staff interview (to catch inconsistencies between documentation and actual practice)
-
Violation risk identification and corrective action planning
-
Audit-ready file preparation
Finding gaps yourself = you fix them before an inspector finds them.
Finding gaps during inspection = violations + fines + increased oversight.
