Details: SUMMARY: Corrosion Control Plan Evaluation with CH2MHill DETAILS: Pete met with SFWB partners Gail, Jim, Lance, Mark, Kim, John & Dave Mustonen of CH2MHill to briefly review CH2MHills data analysis and to use it to outline a plan to enhance SFWBs corrosion control.


High goals were set at a pH of 8 and an Alkalinity of 28 mg/L. However, due to equipment limitations an attempt to reduce alum and increase soda ash as much as possible is the basis of the Corrosion Control Plan that will be proposed September 1st, 007.


Some evaluative sampling will take place as the plan gradually is implemented to assure the plans efficacy and next rounds sampling this autumn will be in compliance. ACTION NEEDED: Await plan.
