The Total Residual Chlorine results ranged from 68 pg/I to 2,148 pg/l. They don't have a chlorine
limit now, but upon permit renewal the permit will include a TRC limit between 17 and 28 pg/l.
PROJECT EQUIPMENT DESCRIPTION:
• Equalization Basin—400,000 gpd capacity, pump station with two 300 gpm pumps.
• Clarifier—400,00 gpd capacity, sludge pumping station, effluent weir.
