Pretreatment & Source Control

NRWS Capacity & Permit

There are two methods to become user of the Non-Reclaimable Waste System (NRWS): (a) Make connection to the NRWS or (b) Truck the wastewater to a NRWS disposal site.

• Method (a) is for an industry that normally discharges continuously with flow of more than 15,000 gallons per week.

• Method (b) is for an industry that normally discharges by batch with flow of 15,000 gallons per week or less.

To use the first method, an industry has to purchase hydraulic capacity in the NRWS, and enter into a Capacity Right Agreement (Agreement) with the Agency. The Agreement dictates the flow rate of wastewater to be discharged to the NRWS. Application form for purchase of capacity is available in the Forms and Links section.

To discharge by second method (b), there is no need to purchase the hydraulic capacity.

Apply for Wastewater Discharge Permit

The permit, which usually has a five-year term, allows discharges to the NRWS. It specifies the discharge requirements and limits for pollutants of concern in an industrial discharge. To apply for the permit, please fill out the permit application (available in the Forms and Links section), and send us, at a minimum, the following items for determination of industry category and applicable discharge requirements:

1. Six (6) sets of plans, drawn to scale (minimum size 11 x 17) for your facility’s:

   • facility layouts and spill containment systems for storage tanks and containers;

   • industrial & sanitary waste lines located within the facility and points of connections to the NRWS or domestic sewers;

   • schematic diagrams of wastewater treatment equipment and process, if any;

   • proposed plans for connection to the NRWS; and

   • proposed monitoring station for the discharge (upstream of connection to the NRWS).

2. A schematic diagram for the water mass balance with average flow rates for water usage and discharge for the facility.

3. Descriptions of manufacturing process, wastewater generation process and wastewater treatment practice, if any.

4. Lists of primary raw materials and products.

5. If possible, a wastewater characteristic report of wastewater from a similar facility that you affiliate with.

6. 6. Other items that are required by the Agency's staff to properly determine industry's category and discharge limits.
