Permits & Engineering Comments:
No treatment system modifications have occured since the last permit was issued. Regional
office should provide insight to extent of treatment. Current permit's supplement page says
nothing of disinfection or dechlorination while the facility meets a fecal limit as well as a
TRC limit. All monitoring frequencies have been modified to comply with the 2B .0500
regulations. Facility's compliance history seems good, with little violation problem. All
sample types are grab as thepermitteddischarge is less than 30,000 gpd.
