1. The SHAC recommended Local Management Levels (LMLs) for all 25 wells in the North and South Management Areas at 15 feet below the Measurable Objective. The committee voted without opposition to expand LMLs from the 14 wells in the current draft to all 25. In a separate vote, it favored a 15-foot offset rather than 20 feet, with one member opposed. A public commenter said his historical back-testing indicated that a 15-foot offset would not have activated the response he tested. The committee favored the earlier warning point.
2. The committee recommended a trigger based on fall measurements below the LML in two consecutive calendar years. Members wanted to avoid language suggesting that groundwater must remain below the LML through the intervening spring recovery period. Staff supported using fall measurements, noting that summer readings can be harder to interpret because pumping complicates static measurements.
