[Ord. No. 1457, § 1, 2-15-2006]
(a) 
Purpose and policy. This article sets forth uniform requirements for direct and indirect contributors into the wastewater collection system of Plymouth Township to effect compliance with applicable state and federal laws required by the Clean Water Act of 1977 and the General Pretreatment Regulations (40 CFR Part 403).
(b) 
Objectives.
(1) 
To prevent the introduction of pollutants into the municipal wastewater system which will interfere with the operation of the system or contaminate the resulting sludge at the POTW(S) servicing the Township.
(2) 
To prevent the introduction of pollutants into the municipal wastewater system which will be inadequately treated and thus pass through the system into receiving waters or the atmosphere or otherwise be incompatible with the system.
(3) 
To improve the opportunity to recycle and reclaim wastewater and sludges from the system.
(4) 
To provide for equitable distribution of the cost for the implementation of the authority's municipal industrial pretreatment program.
(c) 
Provisions for direct and indirect contributors, authorization for monitoring and enforcement activities, setting of fees, etc. This article provides for the regulation of direct and indirect contributors to the municipal wastewater system through the issuance of permits to certain nondomestic users and through enforcement of general requirements for the other users; authorizes monitoring and enforcement activities; requires user reporting; assumes that an existing customer's capacity will not be preempted, and provides for the setting of fees for the equitable distribution of costs resulting from the program established herein.
(d) 
Application of article. This article shall apply to the Township and to persons outside the Township who are users or significant users of the Township collection system. Except as otherwise provided herein, the MIPP coordinator shall administer, implement and enforce the provisions of this article.
(e) 
Agreements to accept wastes of unusual strength. Nothing contained in this article shall be construed as preventing any special agreement or arrangement between the control authority and users or significant users within or out of the Township, whereby a waste of unusual strength or character may be accepted by the control authority by special agreements in writing, executed prior to such acceptance, containing safeguards, limitations and conditions acceptable to the control authority, as long as such wastes do not violate any applicable federal categorical pretreatment standards or requirements.
(f) 
Exceptions to biochemical oxygen demand (BOD), ammonia and suspended solids (SS) limitations. The MIPP Coordinator may grant exceptions to the BOD, ammonia and suspended solids limitations on its own authority based on the request in writing by any Class I industrial user (significant user) in the event the Class I user is unable to adhere to the general limitations set forth herein. The grant of any exception to such limitations under this paragraph is solely within the discretion of MIPP Coordinator and shall be granted subject to the general terms of the permit. The MIPP Coordinator shall make its determination whether to grant an exception to the BOD, ammonia and suspended solids limitations on a case-by-case basis, taking into consideration the impact on the operation of the POTW treatment plant and its ability to operate within the standards established by the control authority's NPDES permit. The basis for this determination shall be in accordance with the compatible pollutant local limits reallocation study prepared from time to time by the control authority's consulting engineers. Any party who is aggrieved from the decision of the MIPP Coordinator regarding the MIPP's decision regarding its request for an exception to the aforementioned limitations may avail itself of the appeal procedure under Sec. 25, Show cause of hearing.
