UST Operator Training

UST Operator Designations

As defined by the OSFM, there are three (3) classes of UST operators:

  • Class A operators are employees with primary responsibility to operate and maintain a UST system;
  • Class B operators are employees who implement the requirements of the UST O&M Plan; and
  • Class C operators are employees who are responsible for responding to alarms or other indications of emergencies caused by spills or releases of UST systems.

At least one of each operator class must be designated for each UST system and employees may be designated for multiple classes of operators.

Training Requirements

The minimum training requirements for employees involved in the operation of UST systems are:

  • Supervisors with direct reports who maintain and operate UST systems must complete Class A operator training;
  • Employees who maintain and operate UST systems must complete Class B and Class C operator training; and
  • Employees who may respond to spills or releases from UST systems must complete Class C operator training.

In most cases, EHS will recommend Class A, B, and C Operator training for all employees involved with the implementation of the UST O&M Plan.

The content and examinations used to train UST operators must be approved by the OSFM. EHS will identify third-party providers who have OSFM-approved training materials.

Training Frequency

The initial training requirements are:

  • Employees who will be designated as Class A and/or Class B Operators must complete training within 30 days of assuming operations and maintenance responsibilities for a UST system; and
  • Employees who will be designated as Class C Operators must complete training prior to being assigned responsibility for spill and release response.

Retraining is required for UST Operators every two years and within 60 days of the issuance of a Notice of Violation from the OSFM.

EHS will maintain the following training records:

  • A list of employees designated as Class A, Class B, and/or Class C Operators; and
  • Copies of training certificates for each active UST Operator for the duration of their employment.

Operations and Maintenance

Operator Inspections and Checks

The following will be performed by the Class A or B operator for each UST system:

  • Monthly inspections;
  • Monitoring of monthly leak detection system tests (currently all University and UCM UST systems are equipped with Veeder Root leak detection systems);
  • Class A or Class B Operator Quarterly inspections; and
  • Recording impressed current system readings in monthly log (when specified by the UST O&M Plan).

Periodic Equipment Testing and Inspections

The following annual and triennial maintenance activities will be performed by contractors licensed by the OSFM:

  • Annual inspections of tank and line leak detection systems;
  • Annual testing of tank and line tightness;
  • Annual inspection of corrosion protection systems;
  • Annual testing and inspection of fuel-dispenser equipment;
  • Triennial sacrificial anode testing; and
  • Triennial spill containment and overfill prevention equipment inspections.

Recordkeeping

To ensure compliance with the OSFM regulations, printed copies of the following records must be maintained at each location of an UST system for at least two (2) years:

  • Monthly leak detection system test results (Veeder Root receipts);
  • Completed Class A or Class B Operator Quarterly inspection checklists;
  • Impressed current logs; and
  • Results of tests and inspections performed by OSFM-licensed contractors.

Electronic copies of these records must also be submitted to EHS for permanent recordkeeping. Instructions for submitting electronic records to EHS are provided in the UST O&M Manuals.

The respective work tracking systems for Facilities Services and Physical Plant will be used to document completion of monthly inspections. Separate work requests must be generated whenever deficiencies are found during the monthly inspection.

Projects

Project Design Phase

Project managers should complete the Project Planning and Design Review Checklist and notify EHS when the project scope includes:

  • Activities which will disturb soil, such as excavations; and
  • Removals, installations, or upgrades or repairs of UST systems.

EHS will advise the project manager on the CDPH and OSFM regulations which apply to these construction activities.

Environmental Site Assessments

Soil contamination can occur when regulated substances are released after an UST is inadvertently struck during construction activities, such as excavations. To prevent releases from UST systems, an environmental site assessment (ESA) must be completed prior to construction activities which will disturb soil to confirm the absence or presence of UST systems at the project site (see Environmental Assessment of Real Estate Transfers for further information).

UST Systems which are present must be addressed prior to commencing construction activities which may potentially strike them.

Removal of UST Systems

When project scope includes removal of UST systems:

  • Removals of UST systems must be coordinated with the CDPH;
  • Environmental consultants will be hired to oversee UST system removals to ensure work is completed in compliance with CDPH and OSFM regulations;
  • Environmental contractors who are licensed by the OSFM will perform the UST removals and obtain and submit the appropriate OSFM and CDPH permits and notifications;
  • Soil remediation will be required if the soil surrounding the UST system is found to be contaminated with the contents of the UST (see Soil Remediation section);
  • EHS will assist project managers in selecting environmental consultants and environmental contractors; and
  • All costs associated with the removal of UST systems, including soil remediation, will be the responsibility of the project.

Installation, Upgrades, and Repairs of UST Systems  

UST systems must meet the performance standards for tank fabrication, corrosion protection, spill and overfill prevention equipment, operation, and release detection equipment described in 41 IAC, Part 175. Employees must not operate the UST System if any of the performance standards are not met.

When the project scope includes installation or modification of UST systems:

  • Installation of UST systems must be coordinated with the CDPH; and
  • Contractors installing, upgrading, or repairing UST systems must be licensed by the OSFM and obtain and submit the appropriate OSFM and CDPH permits and notifications prior to commencing work.

Note: Installations or modifications of UST systems may require further permitting as described in the Title V Air Permit Policy.

Release Notification and Investigation

Above-Ground Releases

Examples of above-ground releases from UST systems include:

  • Spills during deliveries;
  • Overfills and spills when dispensing fuel to vehicles; and
  • Leaks from above-ground components of the UST system.

Immediately report above-ground releases from a UST system to the UCPD, by calling 773.702.8181 or 123, to ensure EHS is paged.

Only employees who have completed Class C operator training are authorized to respond to above-ground releases from UST systems (please refer to the UST O&M Plan for specific spill response procedures). 

Suspected Underground Releases

The following are signs of suspected releases from the underground components of an UST system:

  • Failing results of a monthly Veeder Root test;
  • Presence of product or vapors in soils, basements, sewer or utility lines, or nearby surface water;
  • Erratic behavior of dispensing equipment;
  • Sudden loss of product from the UST;
  • Dead vegetation, such as grass or bushes, located around the UST system; or
  • Unexplained presence of water in the UST.

Immediately report suspected releases to the UCPD, by calling 773.702.8181 or 123, and ask for EHS to be paged.

Notifications to Regulatory Agencies

EHS shall notify the appropriate regulating agencies upon discovery of a suspected release from UST systems. 

Within seven (7) calendar days of the discovery of the suspected release, EHS will submit follow-up communications to the appropriate regulating agencies to provide updated information and results of investigations.

Investigation

All suspected releases will be investigated to confirm the presence or absence of a suspected release from the underground components of an UST system:

  • EHS will lead and coordinate investigation efforts;
  • Investigations of suspected releases may consist of tank and line tightness testing and/or site assessments;
  • Tank and line tightness testing must be performed by a contractor licensed by the OSFM;
  • If the tank and line tightness test results indicate a leak exists, then the appropriate repairs must be immediately initiated to address the leak and a site assessment must be conducted;
  • Site assessments must be performed by an Illinois-licensed Professional Engineer (PE) or Professional Geologist (PG);
  • The department operating the UST system, Facilities Services or Physical Plant, will arrange for tank/line tightness testing when required;
  • EHS will assist the operating department or project manager to arrange for an environmental consultant to conduct site assessments when required;
  • The operating department will be responsible for scheduling and funding tank/line tightness testing and site assessments and providing access to the UST systems; and
  • EHS will submit required follow-up communications with regulatory agencies.
