Persons required to pretreat wastewater in accordance with §
75A-49 above shall provide a statement, reviewed by an authorized representative of the user and certified to by a qualified person indicating whether applicable pretreatment requirements are being met on a consistent basis and, if not, describe the additional operation and maintenance or additional pretreatment required for the user to meet the pretreatment requirements. If additional pretreatment or operation and maintenance will be required to meet the pretreatment requirements, the user shall submit a plan, including schedules, to the Authority. The plan, including schedules, shall be consistent with applicable conditions of the Authority's NPDES permit or other local, state or federal laws.
Discharges of wastewater to the Authority's wastewater facilities from the facilities of any user shall be monitored in accordance with the provisions of Article
VII, §§
75A-42 and
75A-43 of this chapter.
In the event that the federal government promulgates a regulation for a given new or existing user in a specific industrial subcategory that establishes pretreatment standards or establishes that such a user is exempt from pretreatment standards, such federal regulations shall immediately supersede §
75A-49A of this Article.
The Authority shall promptly apply for and obtain authorization
from the EPA to revise discharge limitations for those substances
listed in the Federal Categorical Pretreatment Standards for which
consistent removal occurs in the wastewater treatment facilities of
the Authority. The Authority shall not adopt or enforce discharge
limitations more stringent than the requested limitations until the
state or EPA acts on the application.
