(c) 
Local limits are subject to more stringent standards as established by national pretreatment standards. Local limits are deemed to be pretreatment standards for the purposes of Section 307(d) of the Act, and are enforceable under Section 309 of the Act, potentially subjecting an industrial user to a penalty of twenty-five thousand dollars per day for each violation.

(Ord. 1328 § 1, 1997; Ord. 1520 § 1, 2010)
(a) 
Upon adoption of a national pretreatment standard more stringent than those contained in this chapter, the federal standard shall immediately supersede the limitations listed in this chapter and the affected significant industrial users shall be notified of the new standards and applicable reporting requirements.
(b) 
The significant industrial user shall comply with the national pretreatment standard within the time provided in the federal regulations that establish such standards even if their wastewater discharge permit has not yet been modified to incorporate the new requirement or standard.
(c) 
The significant industrial user shall comply with any applicable requirements under Sections 204(b) and 405 of the Act and Subtitles C and D of the RCRA.
