Virgin oils, Virgin oil/water
mixtures
EMI accepts virgin
petroleum oils generated through many sources, such as the clean up of
spills to land or water,
maintenance activities and cleaning of storage tanks. This material is not “waste oil” by definition in Chapter 860 of the Waste Oil Management Rules Section 4. A (4) & (5).

Documents
Required for Waste Approval and Shipment
EMI requires that each new shipment of virgin
petroleum oil and/or virgin petroleum oil water mixture that is proposed for storage and/or treatment at the facility
be accompanied by a properly executed and approved
"Virgin
Material Origin Statement". EMI requires that the Generator or his/her
authorized representative complete and sign the VMOS. The need for analytical testing
of these waste streams is waived based on the generator’s knowledge
that the waste is from a virgin petroleum source. EMI will issue a
EMI Authorization number for the waste stream prior to
scheduling and acceptance of the waste at the EMI
facility.
Emergency spill response/remediation waste may be accepted at EMI by unlicensed waste transporters if the waste is accompanied by a
“VMOS or “Virgin Spill Letter” certification that the debris is from a virgin fuel/oil spill.
Proper shipping papers must accompany all wastes received
at EMI. EMI accepts nonhazardous materials on a bill of
lading, nonhazardous waste manifest or hazardous waste
manifest (using appropriate nonhazardous designation or
waste code). All waste oil transported into EMI from
out-of-state must be accompanied by a manifest. EMI-approved transporters must
examine their shipping papers to determine accurate drum
counts, quantities, waste types, approval numbers, etc. to
detect any discrepancies that could be corrected prior to
arrival at EMI. Only shipments accompanied by
proper/complete shipping papers, VMOS, and EMI approval
number are accepted at EMI.

Acceptance,
Treatment
and Disposal of This Waste Stream
Upon arrival,
each container of virgin oil
is screened/analyzed for the following parameters at the
EMI facility prior to acceptance:
- Flashpoint (except for
water and non-gasoline petroleum products)
- % Oil Product
- % Water Present
- % Solids Present
- Color
- Total Halogens (by Dexsil Chlor-D-TectÒ
Test Kit; EPA SW 846 Method 9077; ASTM Method D 5384-95
- PCBs (by Dexsil Chlor-N-OilÒ
50 Test Kit; EPA SW 846 Method 9079) More
Info
Virgin oil/water
mixtures are off-loaded and stored in 15,000-gallon capacity aboveground, single-walled steel storage tanks (ASTs) located within a concrete containment dike area.
As necessary, chemical additives (e.g., de-emulsifiers and flocculates) are used to enhance the quality of oil in the tanks.
The water phase, which is decanted from the tanks, is then pumped to the water treatment system holding tanks. After settling, the water is pumped from the holding tanks to the water treatment system feed tank. Wastewater is treated using a combination of additional gravitational separation, chemical treatment, ultra filtration (via a membrane system), and carbon polishing. Ultimately, the treated wastewater is discharged to the local City of South Portland POTW under an Industrial User Wastewater Discharge Permit Number 005.
Wastewater (i.e., waste water with dissolved oil compounds, or no measurable layering of
petroleum oil) may be unloaded directly into the water treatment system holding tanks, provided that the wastewater is suitable for treatment and discharge without phase separation in the waste oil storage tanks. After being pumped to the water treatment system feed tank, water meeting this classification proceeds immediately through a combination of chemical treatment, ultra filtration membrane separation, carbon polishing, and ultimate discharge to the City of South Portland POTW in accordance with the pre-treatment permit limits.
Specification waste oil that is recovered by the
EMI Facility is either offered for sale as a fuel supplement for use in non-industrial boilers and non-industrial furnaces as well as in industrial boilers and industrial furnaces, or shipped to a permitted waste oil facility for bulking.
Off-specification waste oil is offered for sale as a fuel supplement for use only in industrial boilers or industrial furnaces having a heat input
capacity of at least 10 million BTUs/hour or for use as a feedstock to re-refiners, or shipped to a permitted waste oil facility for
bulking.
Sludge generated from the settling of materials throughout the wastewater treatment process is dewatered in a recessed-plate filter press. From the filter press the dewatered sludge is placed in 30-yard roll-off containers prior to being transported off site and disposed of at a properly licensed facility.
