Option #1 – New Storage Pond,Remediate PER, Abandon OR#1 and OR#2
• Construct new PER-1 of approximately 4.0 AC FT or 1.3 MG
• Improve booster stations and install new connection to existing wetwells from
PER-1; install new overflow line from PER-1 to PER
• Remediate PER• Add valves to isolate either PER from
plant outfall and pump stations• Total storage volume would match existing volume ~ 2.1 MG
