Sec. 5802 Design standards and monitoring systems for new facilities.

No underground storage tank or facility shall be installed after the effective date of this ordinance, unless a permit to operate is first obtained from the Permitting Authority. A permit to operate shall not be issued for any underground storage tank or facility installed after the effective date of this ordinance, unless the underground storage tank or facility meets the following requirements:

(a)    Be designed and constructed to provide primary and secondary levels of containment of the hazardous substances stored in them in accordance with the following performance standards:

(1)    Primary containment shall be product-tight.

(2)    Secondary containment shall be constructed to prevent structural weakening as a result of contact with any released hazardous substances, and also shall be capable of storing, for the maximum anticipated period of time necessary for the recovery of any released hazardous substance.

(3)    In the case of an installation with one primary container, the secondary containment shall be large enough to contain at least 100 percent of the volume of the primary tank.

(4)    In the case of multiple primary tanks, the secondary container shall be large enough to contain 150 percent of the volume of the largest primary tank placed in it, or 10 percent of the aggregate internal volume of all primary tanks, whichever is greater.

(5)    If the facility is open to rainfall, then the secondary containment must be able to additionally accommodate the volume of a 24-hour rainfall as determined by a 100-year storm history.

(6)    Single-walled containers do not fulfill the requirement of an underground storage tank providing both a primary and a secondary containment.

(7)    The design and construction of underground storage tanks for motor vehicle fuels storage need not meet the requirements of paragraphs (1) to (6), inclusive, if the primary containment construction is of glass fibre, reinforced plastic, cathodically protected steel, or steel clad with glass fibre reinforced plastic, and any such alternative primary containment is installed in conjunction with a system that will intercept and direct a leak from any part of the tank to a monitoring well to detect any release of motor vehicle fuels stored in the tank and which is designed to provide early leak detection, response, and to protect ground water from releases, and if the monitoring is in accordance with the alternative method identified in paragraph (3) of subdivision (b) of Section 5803. Pressurized piping systems connected to underground storage tanks used for the storage of motor vehicle fuels and monitored in accordance with paragraph (3) of subdivision (b) of Section 5803 shall also be deemed to meet the requirements of this subdivision.

(b)    Be designed and constructed with a monitoring system of detecting the entry of the hazardous material stored in the primary containment into the secondary containment. If water could intrude into the secondary containment, a means of monitoring for water intrusion and for safely removing the water shall also be provided.

(c)    When required by the permitting authority, a means of protection for any primary tank, including an overfill prevention device or an attention-getting high level alarm, or both. Primary tank filling operations of underground storage tanks containing motor vehicle fuels which are visually monitored and controlled by a facility operator satisfy the requirements of this paragraph.

(d)    Different substances that in combination may cause a fire or explosion, or the production of flammable, toxic, or poisonous gas, or other deterioration of a primary and secondary containment so as to avoid potential intermixing.

(e)    If water could enter into the secondary containment by precipitation or infiltration, the facility shall contain a means of removing the water by the owner or operator. This removal system shall also provide for a means of analyzing the removed water for hazardous substance contamination and a means of disposing of the water, if so contaminated, at an authorized disposal facility.

Sec. 5803 Monitoring systems for existing facilities.

No underground storage tank or facility installed on or before January 1, 1984, and for the storage of hazardous substances shall continue to operate unless a permit is obtained by January 1, 1986. No permit to operate such tank or facility shall be issue or remain valid unless the following actions are taken:

(a)    On or before January 1, 1986, the owner shall outfit the facility with a monitoring system capable of detecting unauthorized releases of any hazardous substances stored in the facility, and thereafter, the operator shall monitor each facility, based on materials stored and the type of monitoring installed.

(b)    On or before January 1, 1986, the owner shall provide a means for visual inspection of the tank, wherever practical, for the purpose of monitoring required by subdivision (a). Alternative methods of monitoring the tank on a monthly, or more frequent basis, may be required by the permitting authority.

The alternative monitoring methods include, but are not limited to, the following methods:

(1)    Pressure testing, vacuum testing or hydrostatic testing of the piping systems or underground storage tanks.

(2)    A ground water monitoring well or wells which are down gradient and adjacent to the underground storage tank, vapor analysis with a well where appropriate, and analysis of soil borings at the time of initial installation of the well. The Permitting Authority shall develop regulations specifying monitoring alternatives and shall approve the location and number of wells, the depth of wells and the sampling frequency, pursuant to these regulations.

(3)    For monitoring tanks containing motor vehicle fuels, daily gauging and inventory reconciliation by the operator, if inventory records are kept on file for one year and are reviewed quarterly, the tank is tested for tightness hydrostatically or, when appropriate, with pressure between three and five pounds, inclusive, per square inch at time intervals specified by the State Water Resources Control Board and, whenever any pressurized system has a leak, detection device for tightness hydrostatically or where appropriate, with pressure between three and five pounds, inclusive, per square inch whenever there is a shortage greater than the amount specified by the State Water Resources Control Board.

Sec. 5804 Abandonment.

(a)    No person shall abandon an underground storage tank or close or temporarily cease operating an underground storage tank except as provided in this Section.

(b)    An underground storage tank which is temporarily taken out of service, but which the operator intends to return to use, shall continue to be subject to all the permit, inspection, and monitoring requirements of this Chapter, unless the operator complies with the provisions of subdivision (c) for the period of time the underground tank is not in use.

(c)    No person shall close an underground storage tank unless the person undertakes all of the following actions:

(1)    Demonstrates to the permitting authority that all residual amounts of the hazardous substance or hazardous substances which were stored in the tank prior to its closure have been removed, properly disposed of, and neutralized.

(2)    Adequately seals the tank to minimize any threat to the public safety and the possibility of water intrusion into, or runoff from, the tank.

(3)    Provides for, and carries out, the maintenance of the tank as Permitting Authority determines is necessary, for the period of time the Permitting Authority requires.

(4)    Demonstrates to the permitting authority that there has been no significant soil contamination resulting from a discharge in the area surrounding the underground storage tank or facility.
