High Strength Waste:
Wastewater originating from industrial or commercial business activities that, when discharged to the collection system, has a concentration of total suspended solids (TSS) and/or biochemical oxygen demand (BOD) in excess of 350 mg/l.
High Strength Waste Fee:
A surcharge for TSS and/or BOD discharged at concentrations above 350 mg/l. High Strength Waste Fees shall be collected pursuant to a resolution adopted by the Three Rivers Wastewater Authority Board. and remitted to the TRRWA prior to the end of the calendar month following collection.
Sampling:
Grab sampling will normally be used for sampling intermittent discharges that are consistent in waste strength, and when samples are to be tested for components or characteristics that are subject to significant and unavoidable change during storage (i.e., dissolved gasses, pH, temperature, etc.).
Composite sampling will normally be used for sampling continuous discharges and for sampling variable strength wastewater. Composite samples will normally be collected over a 24 hour period, however, when industrial or commercial discharges occur for less than 24 hrs/day, composite samples will be taken for the duration of the waste discharge.
Sampling frequency will depend upon the nature and source of the waste discharged and its potential to adversely impact treatment plant operations and efficiencies. For discharges having a significant potential for disrupting plant operations, daily sampling may be appropriate. For discharges with a minimal potential for disrupting plant operations, less frequent sampling (i.e., weekly) may be appropriate.
Annual Wastewater Discharge Permit Fees shall be levied on each Significant Industrial User (SIU) each Potentially Significant Industrial User (PSIU), each Potential Significant Commercial User (PSCU), each Industrial User (IU), and each Commercial User subject to a TRRWA Wastewater Discharge Permit. Each permitted User will be evaluated by the Plant Superintendent and the Member Entity where the User discharges and subsequently placed in the appropriate category. Pretreatment Permit Fees are established by a Resolution of the TRRWA Board.
The TRRWA and Member Entities may adopt additional fees to recover the costs of implementing this Policy and operating the TRRWA's and Member Entities' Pretreatment Programs, which may include:
A. 
Fees for monitoring, inspection, and surveillance procedures including the cost of collection and analyzing a User's discharge, and reviewing monitoring reports submitted by Users;
B. 
Fees for reviewing and responding to accidental discharge procedures and construction;
C. 
Fees for filing appeals;
D. 
Fees to recover administrative and legal costs associated with enforcement activity taken to address User noncompliance; and
E. 
Other fees as necessary to carry out the requirements contained herein. These fees relate solely to the matters covered by this Policy and are separate from all other fees, fines, and penalties imposed by the TRRWA or Member Entities.
