Rich, I agree with your concern. The entire Arizona mainline is a potential
concern for carrying PCB's into California. We have verification of this from the last cleaning we did on the San Juan lateral where liquids got past the Gallup C/S scrubbers and PG&E and SoCal both reported elevated liquids in their systems. Analytical results of these liquids in California showed PCB's at regulated levels (ie greater than 50 ppm).

One thing we can't afford to do this time is take a chance of moving any PCB'S further West. There are new scrubbers planned for the West locations in the future.

This section is sufficiently far away from California that PCB issues should be mitigated. It has the highest relative roughness (excluding Gallup to Station 4, which appears to be mostly SCADA calibration errors). Station 3 has more HP than the other stations and therefore more likely to achieve MAOP. The higher HP and reduced pipeline losses will translate to a significantly higher pressure at the discharge of station 2. By my estimation, we will gain 5 MMBTU/D in total system capacity if we reduce the effective roughness of this one section from 0.00077 to 0.00058.
