1. Van Wert, OH Water and Wastewater Element Training
MESH 3.0
Water Management and Conservation

2. Definitions
Water Source: includes all water coming into a plant from municipal or other third party water supply and on-site/off-site wells
Wastewater Source: includes all waters at the site destined for disposal including process wastewater, non-contact cooling water, wash-up water and sanitary (domestic) sources

3. What Does Eaton Require?
Van Wert must be managed in a way that assures compliance with all regulatory requirements AND minimizes the impact of water releases to the community and the environment where the plant operates.

Step 1. Inventory
Water Sources
Water Uses & Wastewater generation
Wastewater discharges

5. Step 1: Inventory Van Wert must identify: Sources:
all sources of incoming water including municipal water sources and on-site wells;
every location in the plant where water is used and where wastewater is generated including
machines
wash-up water
recycled water
sanitary sources

6. Step 1: Inventory Van Wert must identify and/or label:
all waste water handling drains
all discharge points from the facility (including treatment devices)

7. Step 1: Inventory
Map the location of water sources, discharges, and transport in pipes and trenches:
A site should check if sources or uses of water are missing by doing a rough mass balance.
Volume in = Volume out + Stormwater - Evaporation

Step 2. Characterize
Wastewater Volume/Flow
Wastewater attributes 8

9. Step 2: Characterization
All wastewaters generated by the site must be characterized. This evaluation includes:
volume or flow rate;
chemical analysis of the wastewater characteristics
type and concentration of chemical constituents
The plant uses process knowledge, information from SDSs, and chemical analysis to identify all pollutants in the wastewater that could impact the environment.

10. Step 2: Characterization
Characterization must include abnormal operating conditions such as:
process upsets,
by-passes,
start-ups/shut-downs,
chemical “dumping” to sewers,
maintenance activities, etc.

Step 3. Evaluate
Regulatory Requirements
Other (such as third party) 11

12. Step 3: Evaluation of Regulatory and Other Requirements
The site is under an operating National Pollution Discharge Elimination System (NPDES) Permit.
This permit limits the kind and amounts of contamination in the water we send to the City of van Wert.
Items that we are limited for include:
pH Cadmium
Lead Zinc
Mercury Hexavalent Chromium
Total Chromium
The site tests daily and we have a 3rd party test weekly to verify our discharge

13. Step 3: Evaluation of Regulatory and Other Requirements
A site is NOT allowed to discharge wastewater without treatment.
**Any exception to this requirement MUST be approved by Corporate EHS 13

Disposal 14

15. Step 4: Operation (Collection, Treatment and Disposal)
We must collect and transport wastewater in chemically appropriate piping or trenching.
The design of collection systems should be protective of the environment and provide secondary containment in environmentally sensitive areas.
Design of wastewater collection systems should also minimize handling of wastewater in areas that could be flooded with storm water.
Non-specific, general floor drains should be eliminated wherever possible.

16. Step 4: Operation (Collection, Treatment and Disposal)
Our wastewater treatment system must identify key operating parameters for the system including flow rate, zinc levels, pH, and others per our permit
Operating procedures must be developed and deployed to assure that the system is operated at all times in a manner that assures compliance with final discharge limits.

17. Step 4: Operation (Collection, Treatment and Disposal)
Operating procedures must be developed for the wastewater treatment system that address actions to be taken during periods of abnormal production, chemical “dumping”, maintenance activities, and power failure. These procedures should ensure that the plant maintains compliance with permit limitations even under abnormal operating conditions.

18. Step 4: Operation (Collection, Treatment and Disposal)
Plants must include regular documented visual inspection of the operation of the wastewater treatment system, sampling and testing practices, secondary containment and integrity of the collection system into regularly scheduled MESH inspections.
If the plant has any issues with the water discharge, the treatment must be shut down and
EHS notified .

19. Step 4: Operation (Collection, Treatment and Disposal)
Management of Change
Changes to the site’s operation, processes or equipment must include an evaluation of the effects on the site’s water and wastewater inventory, characterization and all requirements described above.
Refer to MESH 1.0 – General Requirements/Planning/Management of Change.

21. Step 5: Document and Train
Employees and contractors must receive training as it pertains to their job function including:
Operation and maintenance of wastewater sources
Operation and maintenance of wastewater collection and treatment systems
Operation of wastewater systems under abnormal or emergency conditions
Sampling, testing, monitoring and recordkeeping procedures
Regulatory, permit, and other requirements
Inspection of wastewater systems’ operation and compliance
Labeling requirements for collection systems and discharges
Any external training and licensing based on regulatory requirements 21
