Hazardous Waste Characterization
Overview
Miramar & Kearny TSDF• Profile the waste drums for proper
disposal• Hazardous Soil Disposal • Vault Dewatering Program
Construction Debris • Lead Paint• Asbestos

Vault Dewatering Program
Sump pump with Filter Sock
Water is tested for odor and
visual content Then pumped to the storm drain
Vault Dewatering with a Tanker
Off loaded into the
OWSTransported to Miramar
Water removed
from vault
Water Discharged to Sewer
Oil skimmed from water
Soil/sludge separated
Water holding tanks
Vault Dewatering Permit Support• Annual Sampling Event – on site sample
pulled and tested by the lab• Research testing for filter sock
development & sump pumps• State Mandated Testing – 4 year study
for all priority pollutants

Rain Event Occurs – Lab gets email alert from our Meteorology Group
Lab Technician samples the rain water as it flows into the storm drain and conducts visual observations
Lab analyzes for• pH• Conductivity• Oil & Grease content• Total Suspended Solids• Permit Specific constituents associated to the industrial activity• Results are submitted annually to the Regional Water Quality Control Board in order to allow legal discharge of rain water From our facilities.
Transformer Oil Program
Investigative Analysis – Used Oil for Selling Depolymerization
of Paper Windings
Oil Quality Trending
The Lab tests the oil for:• Total Acid Number (Corrosion)• Color (sign of aging)• Metal content (gear damage or sign of sparking) • Furans (thermal degradation of paper)• Dissolved gases (flammable gases can be generated)• Viscosity & Surface Tension (sign of aging)• Water content (reveals a leak to the atmosphere, causes
damage) • PCBs (Hazardous waste >5 ppm)
Gives the electrical engineers a health report on the transformers in the system.
Poly Chlorinated Biphenyls
A Bit of Background: Banned in late 1970’s• PCBs are very stable which explains their
persistence in the environment• PCBs are man made and have been used in
many different products, including electrical equipment, surface coatings, inks, adhesives, flame-retardants, and paints.
• Incineration may lead to PCB pollution and produce dangerous by-products, such as hydrogen chloride (HCl) and dioxins.
Poly Chlorinated Biphenyls
• PCBs readily absorb into the skin (fatty tissue) and will accumulate in the body.
• They reduce the fire risk associated with transformers
• Many of our transformers predate the 1970’s.• Exposure to PCB’s has been linked to cancer in animal testing.
Emergency Spill Response
When a transformer is hit by a vehicle and spills oil, the lab will give same day results often within hours of the spill occurring.
Issues of concern: Oil that has entered the storm water conveyance system
Emergency Spill Response
PCB’s Gas Ops Support
Power Plant Work
Cooling Towers require NPDES Permits to discharge. This requires weekly, monthly, quarterly, semi-annual, and annual testing and reporting.
For the Palomar Energy Center we conduct all permit required tests and analyze their storm water for the SWPPP.
Natural Gas Compressor StationsWell Monitoring Program – Remember Erin Brockovich?We test the ground water around all SDGE and SoCal Gas compressor stations for:
Hexavalent Chromium (Cr6+)And more!
Cr6+ was an additive used to prevent corrosion in cooling tower water.
PG&E paid out $333 M to dealwith the Cr6+ contamination to ground water around just 1 of their compressor stations.
Soil Import and Export
Soil being held for testing results
Soil sampling for confirmation of effective clean up.
Soil Import and Export
Soil Quarry Sampling for Import
Preconstruction coring to avoid delays
Air Emission Testing
Linearity Testing for Emissions Stacks
Moreno Compressor Station
CEMS-Continuous emissions monitoring systemRequired to be tested on a quarterly basis• Ensures the CEMS system is in calibration and
functioning normally.
Gas Leaks & Odorant
When a customer is concerned due to an unusual odor….or no odor at all!
Gas employees have handheld devices that can be used effectively for detecting low levels of methane and natural gas.
When the levels are too high, the lab takes an air sample and runs it on a lab instrument to verify if the leak is natural gas.
Tedlar sampling bag
Gas Leaks & Odorant cont’d
When is there is no odor?
Our natural gas is odorized in Nevada but….. • Some new gas lines have to be “pickled” with odorant
if the interior of the pipe absorbs the mercaptan as it flows through the line to the end user.
• The lab has been trained to transport and dispense pure mercaptan into the line with the assistance of the gas crews.

First Pretreatment
Second Pretreatment
Reverse Osmosis
Post Treatment
• Reverse Osmosis water can be slightly acidic• It may be low in minerals that make water
taste good.
Energy Recovery
46% of the energy used to generate the RO water is recovered through capture of the hydraulic energy as the brine is rejected from the membranes.
Brine Discharge & Water Supply
Brine water is mixed into the powerplant cooling water dischargebefore discharging to the ocean.
50 Million Gallons of Drinking water enter our municipal system each day.
The Ocean Plan
Industries that discharge directly into the ocean are highly regulated.
The National Pollution Elimination Discharge System (NPDES) regulates the quality of the water as it exits the plant.
Testing seawater poses challenges for detection at low levels.
The Ocean Plan regulations were based on testing in clean DI lab water. Detecting contaminates in brine water at low levels can be extremely challenging.
The Ocean Plan
Throughout the plant commissioning process our lab provided compliance testing throughout the plant processes.
The Desalination Plant when live on December 14, 2015.
