Industrial Facility Compliance Inspections
- Identification of all wastewater sources
- Inspection of facility process wastewater treatment system
- Wastewater discharge related documentation
- Determination of compliance with federal categorical standards
- Evaluation of compliance with other federal pretreatment requirements
- Assessment of compliance with local limits and actions by the agency
On behalf of a Southern California Sanitary District, EEC Environmental (EEC) performed site compliance inspection of selected industrial users discharging into the Inland Empire Brine Line (IEBL; formerly known as the Santa Ana Regional Interceptor, SARI).
The inspections were part of an audit of the pretreatment programs of the Southern Californian Watershed Project Authority and its member agencies. Industrial users were selectively inspected based on a volume of wastewater discharged and/or industry type in order to evaluate the performance of the overall pretreatment programs.
EEC performed a series of inspections of direct and indirect dischargers into the IEBL. Direct dischargers are typically close enough to construct a direct connection to the IEBL and produce enough waste to justify the connection cost economically. Indirect dischargers generate waste streams that are high in total dissolved solids and are not located close enough to the IEBL to make a direct connection.
Instead, the wastewater is hauled to and discharge at Liquid Waste Hauler (LWH) discharge stations. In general, the volume of wastewater discharged at these stations varies and can vary from one or two truckloads per week to 100,000 gallons per day in some cases. Liquid waste from indirect dischargers is disposed of at discharge stations using a permitted commercial LWH permitted by the Southern Californian Watershed Project Authority.
