SECTION 252:623-5-2. Additional pretreatment measures

(a)   Whenever deemed necessary, the DEQ 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 wastestreams from industrial wastestreams, and such other conditions as may be necessary to protect the POTW and determine the user's compliance with the requirements of this Chapter.

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

(c)   Grease, oil, and sand interceptors shall be provided when, in the opinion of the DEQ, 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 by the DEQ and shall be so located 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.

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