Objective of Inspections
• Establishing permitting program and effluent limits
• Ensuring proper operations an maintenance of facilities
(treatment units, distribution systems, collections
systems)
• Ensuring accuracy and reliability of self-monitoring
• Surface water standards
• Residuals management
Inspection Preparation
• DWR’s File Review:
-Treatment Unit Components
-Receiving Stream
-Discharge Monitoring Reports & Non-Discharge
Monitoring Reports
-Compliance history (SSOs, Bypass, limit violations, SOCs,
residuals management)
-Monitoring/reporting special permit conditions
-Operator in Responsible Charge (ORC) and back-up ORC
-24 hour staffing, Certified Lab, Review DMRs
Inspection Components
• Arrival/inspection introduction (representatives, objects,
order of events etc.)
• Facility treatment unit/lab Inspection
• Records review
• Closing conference
• Inspection report
• Follow up (e.g. written response and/or follow up site
visit, as appropriate.)
Plant Walk-Through
• Review Industrial production process
• Waste stream: understand wastewater sources
• Wastewater treatment processes: (headworks to final
effluent)
• Inspect Outfall and/or land application field (review
NDMR)
• Review: Flow measurement, Sampling
methods/location, review onsite data
collection/measurements, and calibrations procedures
Problem Indicators
• Excessive equipment noises
• Hydraulic overloads,
• Odors,
• Corrosion,
• Scum
• Inoperable units
• Evidence of spills
(staining, impacts to vegetation, normal water level
changes, sample results, application field conditions etc.)
• other
Records Review
• Is the data reliable and accurate
• Has each parameter been monitored and reported as
specified in the permit
• Have all result been reported
•
Checklist Inspection Items
• Is the permit current (correct name, mailing address,
physical locations)
• Effective/expiration dates (make sure ORC work off
current permit conditions)
• Outfalls, equipment listed in permit present on-site,
receiving stream
• Review last inspection(s) – follow up items
• Permit violations & enforcement actions
• Equipment changes
• Laboratory records, Chain of Custody sheets
• Equipment calibrations,
• Expiration dates (standards and buffers)
Records Inspection
Continued
• Permit, SOC/JOC
• Monitoring Records (DMR, NDMR - Daily, weekly,
monthly, quarterly, monitoring violations, Operator log
• Laboratory records: calibration, bench sheets, temp logs,
compare DMR and lab data, COC, holding time for fecal,
certified lab
• Sampling and analytical data results: date, place, and
time of sampling; individual sampling; date analysis was
performed; individual who performed analysis; analytical
methods used; results of each analysis
Facility operating records to
be reviewed include
• flow meter calibration records (required to be calibrated, at a
minimum, annually)
• equipment maintenance records
• amount and type of chemicals used
• ORC log book
• weather conditions, if required
• sludge use and disposal activity
• noncompliance information (does the facility notify DWR
within 24 hours on noncompliant events, and follow up with
letter in 5 days)
• Data trends (winter vs. summer, consistency, variance,
unrealistic numbers etc.)
Closing Conference
• Post inspection conference/discussion
• Discuss findings with ORC/permittee immediately after
the inspection
• Allows for opportunity to gather missing information
• Everyone has opportunity to ask questions
• Present findings and deficiencies
