Load Rejection Notice

Load Rejection Notice — Regulatory-Compliant Contamination Response

The Load Rejection Notice is issued when the 905WOOD Digital Refinery detects contamination that exceeds acceptable thresholds for clean wood processing. This document serves as both an operational directive and a regulatory compliance record under Ontario Regulation 347.

Rejection triggers include TCLP (Toxicity Characteristic Leaching Procedure) exceedance at 905WOOD auto-reject thresholds — Arsenic above 2.5 mg/L, Lead above 5.0 mg/L, or Chromium above 5.0 mg/L. These thresholds are more conservative than standard regulatory limits, reflecting the Precautionary Principle embedded in the Digital Refinery architecture.

Each notice documents: the specific contaminant(s) detected and measured values, the regulatory basis for rejection citing O.Reg 347 Schedule 4, recommended disposal routing to appropriately licensed facilities, the AI classification confidence score and model version used, and photographic evidence captured at the Compliance Gate.

The Load Rejection Notice integrates with the RPRA Hazardous Waste Program Registry when contamination levels require hazardous waste manifesting, automatically triggering Part A manifest generation for loads that exceed standard TCLP limits. This automated handoff between Layer 1 Intake and Layer 3 Regulatory processing ensures zero manual compliance gaps.

For general contractors and project managers in the Hamilton and GTA region, the Load Rejection Notice provides defensible documentation that waste was properly characterized and routed — critical for demonstrating due diligence under Ontario environmental regulations and avoiding CIRCIL Levy exposure on misclassified loads.
