§ 90-127. Pretreatment.

(a)

Pretreatment facilities . Users shall provide wastewater treatment as necessary to comply with this article and shall achieve compliance with all categorical pretreatment standards, local limits, and the prohibitions set out in this article within the time limitations specified by EPA, the state or the city, whichever is more stringent. Any pretreatment facility shall be provided, operated, and maintained at the user's sole cost and expense. Detailed plans describing such facilities and operating procedures must be approved in writing by the city before such facilities are constructed. The review and approval of such plans and operating procedures shall not relieve the user from the responsibility of modifying such facilities as necessary to produce a discharge in compliance with this article.

Upon a finding that a user meeting the criteria of an industrial user as defined in this article has no reasonable potential for adversely affecting the ECRWWTF's operation or for violating any pretreatment standard or requirement, the city may at any time, on its own initiative or in response to a petition received from an industrial user, and in accordance with Rule 62-625.500(2)(e), F.A.C., determine that such industrial user should not be considered a significant industrial user.

(b)

Additional pretreatment measures.

(1)

Whenever deemed necessary, the city may require users to restrict their discharge during peak flow periods, designate that certain wastewater be discharged only into specific sewers, relocate and/or consolidate points of discharge, separate sewage waste streams from industrial waste streams, and such other conditions as may be necessary to protect the WWF and determine the user's compliance with the requirements of this article.

(2)

The city may require any person discharging into the WWF to install and maintain, on their property and at their sole cost and expense, a suitable storage and flow-control facility to ensure equalization of flow. A wastewater discharge permit may be issued solely for flow equalization.

(3)

Grease, oil, and sand interceptors shall be provided when, in the opinion of the city, they are necessary for the proper handling of wastewater containing excessive amounts of grease and oil or sand; except that such interceptors shall not be required for residential users. All interception units shall be of type and capacity approved in writing by the city and shall be installed at a location on the premises to be easily accessible for cleaning and inspection. Such interceptors shall be inspected, cleaned, and repaired regularly, as needed, by the user at their expense.

(4)

Users with the potential to discharge flammable substances shall be required to install and maintain an approved combustible gas detection meter.

(c)

Accidental discharge/slug control plans. At least once every two years, the city shall evaluate whether to require each significant industrial user to adopt an accidental discharge/slug control plan. Alternatively, the city may develop such a plan for any user. 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., and shall address, at a minimum, the following:

(1)

Description of discharge practices, including non-routine batch discharges;

(2)

Description of all stored chemicals;

(3)

Procedures for immediately notifying the city of any accidental or slug discharge in accordance with section 90-129; and

(4)

Procedures to prevent adverse impact from any accidental or slug discharge. Such procedures include, but are not limited to, inspection and maintenance of storage areas, handling and transfer of materials, loading and unloading operations, control of plant site runoff, worker training, building of containment structures or equipment, measures for containing toxic organic pollutants, including solvents, and/or measures and equipment for emergency response.
