The purposes of this chapter are to set forth specific
discharge limitations (hereinafter referred to as "local limits")

health of workers at the Ithaca Area Wastewater Treatment Facility
(POTW), and to improve opportunities to recycle and reclaim municipal
and industrial wastewaters and sludges.

This chapter shall apply to all users of the POTW
in the Towns of Ithaca and Dryden and City of Ithaca and to persons
who are, by resolution, agreement, contract, or permit with the municipalities,
Special Joint Committee, or POTW, users of the POTW.
The definitions set forth in § 264-3 of this chapter, as they may be revised from time to time, shall apply to the words in this article.
