The provisions of this chapter shall not be deemed a limitation upon the County or
Authority to enter into agreements, and to recover costs relating thereto, with any
user relating to treatment, pretreatment, or other matters in furtherance of the provisions
of this chapter and the purposes thereof, and not inconsistent therewith, when unique,
unusual, or extraordinary circumstances require such special agreements; provided,
however, that no such agreement shall authorize an extension of the final dates for
compliance with required federal standards nor waive such standards.
