(a) Each nondomestic user must provide and maintain at the user’s sole expense secondary spill containment structures (including diking, curbing or other appropriate structures) adequate to protect all floor drains from accidental spills and discharges to the POTW of any pollutants or discharges regulated by this chapter.
(b) The containment or curbing shall be sufficient to hold not less than 150% of the total process area tank volume and not less than 150% of liquid polluting material stored or used, unless a lesser containment area or alternate control measures are approved in advance by the POTW Manager.
(c) The containment area shall be constructed so that no liquid polluting material can escape from the area by gravity through the building sewers, drains, or otherwise directly or indirectly into the POTW. All floor drains found within the containment area must be plugged and sealed.
(d) Spill troughs and sumps within process areas must discharge to appropriate pretreatment tanks.
(e) Emergency containment shall also be provided for storage tanks that may be serviced by commercial haulers and for chemical storage areas.
(f) Solid pollutants shall be located in security areas designed to prevent the loss of the materials to the POTW.
(g) Detailed plans showing facilities and operating procedures to provide the protection required by this Section shall be submitted to the POTW Manager for review, and shall be approved by the Manager before construction. Construction of approved containment for existing sources shall be completed within the time period specified by the POTW Manager.
(h) No new source shall be permitted to discharge to the POTW until emergency containment facilities have been approved and constructed as required by this section.
(i) The POTW Manager may order a user to take interim measures for emergency containment as determined necessary by the Manager under the circumstances.
