Tim Church was present during the inspection. A review of records, data, treatment components, structures, fields, etc. was completed. This review reflected compliance with the subject permit.

No industries in vicinity, however it was believed to be caused by slug discharges from local brewery. Secondary Clarifier Is the clarifier free of black and odorous wastewater?
