CRA Waste Reduction Case Studies
Some examples of how CRA’s Waste Services group supports our clients with waste minimization strategies:
Haz Waste Minimization Practice in Field Petroleum Contact Water Reclamation Tank Sludge Oil Recovery and Treatment Path to Zero Landfill
Haz Waste Minimization Practices
Monitoring well installation – field and contractor guidance
Well drilling utilizing grout - potential for high pH sludge and water residuals
Many monitoring wells are installed at CESQG and SQG locations
Prior to drilling project, CRA provides the project manager and client with hazardous waste minimization guidance
Haz Waste Minimization Practices
Grout using a Tremie pipe instead of grouting through the augers (as approved by the specific county)
Mix limited amount of grout to avoid any excess Separate any solids in the decontamination water from
liquid Record pH of decontamination water once it is drummed Record pH of decontamination water prior to pick-up at
site Limit the quantity of decontamination water as applicable
to project to maintain CESQG or SQG status
Monitoring Well Installation
Petroleum Contact Water Reclaim
Generation of water containing crude oil, gasoline, jet fuel, or diesel products Characteristic concerns – flammability, benzene
Contact water is shipped as commercial chemical product for reclamation
Exempt from solid waste regulations per 40 CFR 261.2(c)(3)
Same exemption applies to fuel product impacted debris & absorbents
Petroleum Contact Water Reclaim
Some states regulate maximum percentage of water present as requirement of exemption – check with MDNR for guidance
Tank Cleaning Project – Oil Sludge
Tank cleaning project at crude oil pump station Original project estimated 30 roll off containers 113 roll off containers of oily sludge generated RCRA hazardous for benzene Estimated T&D = $2.2M
Alternative proposal to treat sludge on site, recover oil and reduce waste generated
Tank Sludge On Site Oil Recovery
First, completed bench testing to ensure treatment process would be successful
On Site Treatment Requirements (CA): Temporary Treatment Unit (TTU) Permit 30-day extension for hazardous waste storage
Contractor mobilized equipment and set up processing in one week of permit approval
Processed sludge and process water tested non-hazardous (CA state regulated waste)
Tank Sludge Oil Recovery Impacts
2,070 barrels of oil reclaimed from sludge Estimated value of $207,000 Sludge volume reduced from 113 to 30 roll
off bins (75%) 100% RCRA hazardous waste reduction Total T&D cost savings = $433,000 Total cost savings (including oil) =
$640,000
Tank Sludge Project – Next Time
Treatment directly from tank during cleaning process Eliminates hazardous waste generation No TTU permit requirement ($12K savings) No storage issue Eliminates need for open top bin rental and
cleaning costs ($300K savings)

Path to Zero Landfill
Audit current recycling and trash generation Verify effective container placement and
labeling Are materials handled from production to
proper disposition locations within facility? Complete landfill waste audit – dumpster dive!
Create baseline in order to measure and monitor improvements
Path to Zero Landfill, cont.
Adjust recycling/reuse programs: Ensure containers are easily accessed by
employees Ensure containers are labeled – clear, color
coded, consistent throughout facility Transparent bags in multiple colors can help
with location and material type differentiation Ensure material handlers are trained and have
reference document • Material type flow diagram
Path to Zero Landfill, cont.
Waste Audit Conduct trash audit on site, or coordinate audit at
landfill or transfer station Measure trash constituents by volume/weight Develop base metrics and improvement goals
Employee Engagement Ask for suggestions, implementation assistance,
establish incentives, and celebrate achievements Provide regular updates & make readily available
Path to Zero – Examples
Path to Zero Landfill, cont.
US Zero Waste Business Council www.uszwbc.org Certification for Zero Waste Requirements
• 90% diversion from landfill/incineration for non-hazardous wastes
• Zero Waste Policy in place• Data documented for base year and on-going
monitoring• Submit data to USZWBC annually• Recertification every three years
