## The West Lake Corridor Context

The **West Lake Corridor (Monon Line)** opened **March 31, 2026**, introducing:
- 8.3 miles of double-track electrified rail
- 25 kV AC overhead catenary system
- 4 new stations: Hammond Gateway, South Hammond, Munster, Dyer
- Frequent service (trains every 15-20 minutes during peak)

### Why This Matters for EMF

1. **Overhead catenary systems** generate time-varying magnetic fields at 60 Hz and harmonics
2. **Traction power substations** (TPSS) create localized high-intensity fields
3. **Proximity to industrial facilities** means workers may experience **compounded exposure** from:
   - Industrial electrical systems
   - New electrified rail infrastructure
   - Existing utility corridors

## The Opportunity

### For the Region
- **First baseline dataset** on ELF/EMF in a major industrial corridor
- Positions NWI as a leader in **occupational health monitoring**
- Creates **replicable model** for other industrial regions

### For Industry
- **Due diligence documentation** for regulatory compliance
- **Proactive risk management** — baseline established before any health concerns arise
- **Worker safety leadership** — demonstrates commitment to employee well-being

### For Workers
- **Transparency** — workers know what fields they're exposed to
- **Informed consent** — data-driven decisions about workplace conditions
- **Long-term health monitoring** — establishes foundation for longitudinal studies

## What We're NOT Doing

- Targeting any specific company
- Claiming EMF causes disease
- Seeking regulatory action
- Disrupting operations

## What We ARE Doing

- Establishing baseline data
- Measuring actual field levels
- Creating a regional dataset
- Supporting future research
