§ 53.064. PREVENTION OF ACCIDENTAL AND SLUG DISCHARGES.

(A)

Where determined by the Director, a user shall provide protection from accidental discharge of restricted and prohibited materials or other substances regulated by this Chapter. Facilities to prevent accidental discharge of prohibited and restricted materials shall be provided and maintained at the owner's expense.

(B)

Prevention of accidental discharges requires, but is not limited to, providing secondary containment for storage of potentially hazardous and/or regulated materials. The containment requirements are those now specified in, but not limited to, 40 CFR 264.170 through 176; City of Delray Beach Code of Ordinances Sections 96.40 through 96.47; Article 14, Chapter B, Section 6, Subsection C of the Palm Beach County Unified Land Development Code. Containment requirements must also meet or exceed the following criteria of this subchapter:

(1)

Containment Volume. Containment volume to be provided shall be one hundred fifty (150) percent of the total stored material.

(2)

Storage Sheltering. All outdoor storage shall be sheltered from rainfall, or a suitable means of removing rainwater from secondary containment areas shall be provided.

(3)

Conditions of the Stored Vessel. All stored containers shall be maintained in sound condition. No rust, corrosion or other signs of deterioration of the primary containment wall shall be permitted. All stored containers shall be closed and sealed during storage.

(4)

Segregation of Chemically Reactive Contents. Materials which are potentially reactive with each other shall not be stored in the same containment area, unless physical barrier separations are provided within the common area.

(5)

Standby Materials/Equipment. Absorbents and pumps for pumping out spills shall be available when needed.

(6)

Design of Containment Floor/Base. The floor or base of the containment area on which the stored vessels rest shall either be sloped or raised or provided with a drain faucet to prevent or minimize contact between the storage container wall and spilled content.

(7)

Materials of Construction for Containment. The walls, sidings and floor or base of the containment area shall be constructed of materials which are chemically inert with the stored materials and which render the provided containment volume leak proof.

(C)

On the request of the City, the user shall be required to submit detailed plans showing facilities and operating procedures to provide this protection. All required users shall complete this plan within ninety (90) days after notification by the City. If further required by the City, a user who commences contribution to the Public Sewers after the effective date of this Chapter shall not be permitted to introduce pollutants into the system until accidental discharge procedures have been approved by the City. Review and approval of those plans and operating procedures shall not relieve the industrial user from the responsibility to modify the user's facility as necessary to meet the requirements.

(D)

The City shall evaluate, at least once every two (2) years, whether each significant industrial user needs a plant to control slug discharges. New significant industrial users must be evaluated within one year of being designated a significant industrial user. Significant industrial users are required to notify the City immediately of any changes at its facility affecting the potential for a slug discharge. If the City decides that a slug control plan is needed, the plan shall be prepared in accordance with the requirements of Rule 62-625.500(2)(b)(6), F.A.C.

(E)

In the case of an accidental discharge, including slug discharges and prohibited discharges, it is the responsibility of the user to immediately notify by telephone the Director, the Executive Director, and the City. The notification shall include location of discharge, type of material, concentration and volume, and corrective actions.
