[Ord. 156, 4/26/1994, § 1.0]
1. 
The objectives of this Part are:
A. 
To prevent the introduction of pollutants into the East Rockhill Township wastewater collection and PWTA treatment system that will interfere with its operation, contaminate the biosolids generated at the PWTA wastewater treatment plant or will otherwise be incompatible with the system.
B. 
To prevent the introduction of pollutants into the Township's wastewater collection and the PWTA treatment system that will be inadequately treated and thus will pass through the system into the receiving waters or the atmosphere.
C. 
To protect the environment, the general public, Township and PWTA personnel against the hazards associated with discharges of toxic or otherwise incompatible pollutants into the sewer system.
D. 
To improve the opportunity to recycle and reclaim industrial wastewaters and biosolids from the wastewater treatment system.
E. 
To provide for equitable distribution of the cost for the development and implementation of the PWTA's Industrial Pretreatment Program and other improvements to the wastewater collection and treatment system.
F. 
To help assure the PWTA's compliance with its National Pollutant Discharge Elimination System (NPDES) permit, biosolids use and disposal requirements, the Clean Water Act, the General Pretreatment Regulations and any other state or federal laws which with the Township or PWTA must comply.
2. 
The provisions of this Part will be implemented and enforced by the Township and the PWTA Manager through issuance of wastewater contribution permits to those industrial/commercial users meeting the EPA's definition of a significant industrial user (SIU) through monitoring, reporting and enforcement of this Part with these significant industrial users and all other users. This Part also assumes that the capacity of the sewer system allocated to existing customers will not be preempted and provides for the setting of fees for the equitable distribution of costs resulting from development and implementation of the program established herein.
3. 
Except as otherwise provided herein, the provisions of this Part shall be administered, implemented and enforced by the PWTA Manager and by the Township.
[Ord. 156, 4/266/1994, § 1.2; as amended by Ord. 192, 4/18/2000; and by Ord. 264, 8/16/2011]

(1) 
The building, structure, facility or installation is constructed at a site at which no other source is located;
(2) 
The building, structure, facility or installation totally replaces the process or production equipment that causes the discharge of pollutants at an existing source; or
(3) 
The production or wastewater-generating processes of the building, structure, facility or installation are substantially independent of an existing source at the same site. In determining whether these are substantially independent, factors such as the extent to which the new facility is integrated with the existing plant and the extent to which the new facility is engaged in the same general type of activity as the existing source should be considered.

(3) 
Contributes a process waste stream that makes up 5% or more of the average dry-weather hydraulic or organic capacity of the PWTA treatment plant.
(4) 
Is designated as such by the Township on the basis that the user has a reasonable potential for adversely affecting the operation of the treatment plant, the quality of the biosolids generated at the PWTA WWTP or for violating any pretreatment standard or requirement.
SIGNIFICANT INDUSTRIAL USER PERMIT

SIGNIFICANT NONCOMPLIANCE
An industrial user or user is in significant noncompliance if its violation meets one or more of the specific criteria set forth in 40 CFR 403.8(f)(2)(viii). For purposes of this definition, a user is in significant noncompliance if its violations meet one or more of the following criteria:
(1) 
Chronic violations of wastewater discharge limits, defined here as those in which 66% or more of wastewater measurements taken during a six-month period exceed (by any magnitude) a numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(1);
(2) 
Technical review criteria (TRC) violations, defined here as those in which 33% or more of wastewater measurements taken for each pollutant parameter during a six-month period equal or exceed the product of the numeric pretreatment standard or requirement, including instantaneous limits, as defined by 40 CFR 403.3(1), multiplied by the applicable criterion (1.4 for BOD, CBOD, TSS, fats, oils and grease, and 1.2 for all other pollutants except pH);
(3) 
Any other violation of a pretreatment standard or requirement as defined by 40 CFR 403.3(1) (daily maximum, long-term average, instantaneous limit or narrative standard) that the PWTA determines has caused, alone or in combination with other discharges, interference or pass through (including endangering the health of municipal personnel or the general public);
(4) 
Any discharge of pollutants that has caused imminent endangerment to the public health and welfare or to the environment, or has resulted in the PWTA's exercise of its emergency authority to halt or prevent such a discharge;
(5) 
Failure to meet, within 90 days of the scheduled date, a compliance schedule milestone contained in a wastewater contribution permit or enforcement order for starting construction, completing construction, or attaining final compliance;
(6) 
Failure to provide within 45 days after the due date, any required reports, including baseline monitoring reports, reports on compliance with categorical pretreatment standard deadlines, periodic self-monitoring reports, and reports on compliance with compliance schedules;
(7) 
Failure to accurately report noncompliance; or
(8)

SLUG DISCHARGE OR SLUG LOAD
Any discharge of a nonroutine, episodic nature, including, but not limited to an accidental spill or noncustomary batch discharge or a discharge at a flow rate or concentration that could cause a violation of any pretreatment standard set forth in accordance with § 18-211 or § 18-231.
SLUG DISCHARGE/SLUG LOAD
Any pollutant released in a discharge at a flow rate or concentration which will cause a violation of the specific discharge prohibitions in 40 CFR 403.5(b) or § 18-211 of this Part and/or any discharge of a nonroutine nature or an episodic nature, including but not limited to accidental spills or noncustomary batch discharges, which has a reasonable potential to cause interference or pass-through or in any other way violate the PWTA's prohibited discharge standards, local limits, NPDES permit conditions or any other condition of its rules and regulations.
