Division of Petroleum & Chemical Safety
The Division of Petroleum & Chemical Safety was created to manage the problems caused by the thousands of underground storage tank systems containing petroleum or hazardous chemicals. The division regulates petroleum and chemical storage tanks through registration to ensure the protection of public health and safety.
The division has registered more than 73,000 tanks in Illinois. Other duties include issuing permits for all tank installations, removals, repairs, upgrades, relining and abandonment-in-place. Eligibility and deductibility determinations are also made to determine if a tank owner can access the leaking underground storage tank fund. Inspectors in this division respond to petroleum and chemical leaks and spills.

Notification to Contractors and Dispensing Facility Owners/Operators
Questions have been asked regarding language in our Motor Fuel Dispensing Facilities regulations pertaining to the shear valves required under dispensers, as found at 175.450(e)(12):
Shear Valve. Pressurized piping systems require a listed rigidly anchored
emergency shutoff (shear) valve installed in the supply line at the base of
each individual dispenser. The valve shall incorporate a fusible link or other
thermally activated device, designed to close automatically in the event of
severe impact or fire exposure.
The questions were often in reference to the requirement for dispensing facilities found in 175.210, 175.220, 175.230, 175.240 & 175.250 that 'all shear valves (shall be) visually inspected, at least annually to ensure that they are functioning properly and that the dispenser is mounted properly" 175.210(i). Like the Emergency Shutoff Switch annual test in the same section, the annual "visual inspection" can be done by the owner/operator or a contractor so designated to perform the inspection. This Notification serves the purpose of clarifying what criteria to use to "ensure that (the shear valves) are functioning properly." These criteria match what OSFM and Chicago Dept. of Public Health UST inspectors use:
- All shear valves shall be mounted using a listed rigid anchor.
- All shear valves shall be mounted securely to the listed rigid anchor.
- All shear valves shall be mounted at the proper height relative to grade following the shear valve manufacturer's installation instructions.
- All shear valves shall be maintained in proper working condition.
- In addition, the dispensers themselves will also be inspected when the shear valves are checked to confirm that each dispenser is properly and securely mounted to its island.
This is not a change to our regulations, just a clarification of what our inspectors use to determine proper shear valve mounting and placement. To further clarify the point about placement relative to grade, as in any equipment installation, manufacturer's specifications must be followed. Most models of shear valves need to be mounted with the shear point within 1" or 1/2" of grade using the top of the dispenser island as the reference for grade. If your approved shear valve has mounting criteria outside of those common parameters, have documentation available from the manufacturer to show the inspector so he knows that the mounting is acceptable. This must be from the manufacturer. A letter from a contractor alone will not suffice.
A form has been added to UST Applications and Forms to assist you in documenting this required annual visual inspection. The completed signed form will stay with the station records for our inspectors to check during an inspection to document and verify that all shear valves have been inspected annually.
Notice to UST Contractors
Posted: October 28, 2013
Since the promulgation of our current UST regulations on September 1, 2010, there has been the requirement for a hydrostatic test on all containment sump installations:
A hydrostatic test will be performed on all containment installations (including all submersible, piping and fill sumps) as follows:
1) All penetrations, including electrical, must be completed prior to testing.
2) Containment is to be filled with water to a height that covers the highest penetration by 2 inches.
3) Minimal backfilling that may be necessary for support of the containment sump is allowed prior to the test.
4) Test duration is 30 minutes and performed under PAI Time and Date Certain requirements with no drop in water level. 175.410(h)(1-4)
Up to this point the requirements have been followed by contractors and checked by OSFM inspectors on containment installations except for spill sumps. The regulation explicitly includes "spill sumps" as seen above. Accordingly, from this point forward, spill sumps will also be hydrostatically tested after installation, replacement or minor maintenance repairs to insure the sumps are liquid tight, as per the regulation copied above.
Updates at our website will be seen on the Applications & Forms page to the following forms:
A permit must be obtained for installation or repair of any containment sump, as per 175.300(f)(11)(B). If work being done on a spill sump falls under like-for-like replacement criteria, a permit is not required but a hydrostatic test is. That will require submission of a "Required Job Schedule for Testing" form, and if indicated, a 'Failed Test Results Report" form. Evidence of spill sump like-for-like replacement without the required test schedule form will be a violation.
