(A) Containment devices. The owner/operator of a facility must provide containment devices adequate in size to contain on-site any unauthorized release of regulated substances from any area where these substances are either stored, handled, treated, used, or produced. Containment devices shall prevent such substances from penetrating into the ground. Design requirements for containment devices include:
(1) The containment device shall be large enough to contain 110% of the volume of the container in cases where a single container is used to store, handle, treat, use, or produce a regulated substance. In cases where multiple containers are used, the containment device shall be large enough to contain 150% of the volume of the largest container or 10% of the aggregate volume of all containers, whichever is greater.
(2) All containment devices shall be constructed of materials of sufficient thickness, density, and composition to prevent structural weakening of the containment device as a result of contact with any regulated substance. If coatings are used to provide chemical resistance for containment devices, they shall also be resistant to the expected abrasion and impact conditions. Containment devices shall be capable of containing any unauthorized release for at least the maximum anticipated period sufficient to allow detection and removal of the release.
(3) If the containment device is open to rainfall, then it shall be able to accommodate the volume of precipitation that could enter the containment device during a 24-hour, 100-year storm, in addition to the volume of the regulated substance storage required in division (A)(1) above.
(4) Containment devices shall be constructed so that a collection system can be installed to accumulate, temporarily store, permit detection of, and permit removal of any storm runoff or regulated substance.
(5) Containment devices shall include monitoring procedures or technology capable of detecting the presence of a regulated substance within 24 hours following a release.
(B) Regulated substances management plan.
(1) Plan required.
(a) A regulated substances management plan indicating procedures to be followed to prevent, control, collect, and dispose of any unauthorized release of a regulated substance shall be required as a condition of each operating permit. If a spill prevention control plan or similar contingency plan has been prepared in accordance with state or U.S. Environmental Protection Agency requirements, a regulated substance management plan is not required as long as all of the regulated substances are included in the spill control plan.
(b) The regulated substances management plan shall include:
1. Provisions to address the regulated substances monitoring requirements.
2. Provisions to train employees in the prevention, identification, reporting, control, disposal, and documentation of any unauthorized release of a regulated substance.
(2) Monitoring required. The owners or operators of all new facilities shall implement regulated substances monitoring as part of the regulated substances management plan required by § 58.080 of this chapter. Visual monitoring must be implemented unless it is determined by the village to be infeasible.
(3) Monitoring activities. All regulated substance monitoring activities shall include the following:
(a) A written routine monitoring procedure which includes, when applicable: the frequency of performing the monitoring method, the methods and equipment to be used for performing the monitoring, the location(s) from which the monitoring will be performed, the name(s) or title(s) of the person(s) responsible for performing the monitoring and/or maintaining the equipment, and the reporting format.
(b) Written records of all monitoring performed shall be maintained on-site by the operator for a period of three years from the date the monitoring was performed. The village may require the submittal of the monitoring records or a summary at a frequency that the village may establish. The written records of all monitoring performed in the past three years shall be shown to the village upon demand during any site inspection. Monitoring records shall include but not be limited to:
1. The date and time of all monitoring or sampling;
2. Monitoring equipment calibration and maintenance records;
3. The results of any visual observations;
4. The logs of all readings of gauges or other monitoring equipment, or other test results; and
5. The results of inventory readings and reconciliations.
(4) Inspection and maintenance. Procedures for the in-house inspection and maintenance of containment devices and areas where regulated substances are stored, handled, treated, used, and produced shall be identified in the operating permit for each facility. Such procedures shall be in writing, and a log shall be kept of all inspection and maintenance activities. Such logs shall be submitted to the Director of Public Works with the renewal applications available for inspection at other times upon 48 hours notice. Inspection and maintenance logs shall be maintained on-site by the owner or operator for a period of at least three years from the date the monitoring was performed.
