INITIAL REVIEW ENGINEERING REPORT 

PMN: 12-0167

Focus Ready Draft 2/13/2012

ENGINEER: Avcin \ DDH

PV (kg/yr): 82,000,000 YX

SUBMITTER: Dakota Gasification Company

USE: For blending with petroleum oil for feed to

refineries (80%) and for feedstock to a hydrocracker

process to make different cuts of fuels to blend with

other fuels (20%). P2REC: CRSS: Drop (Not verifiable).

P2 Claim: Normally, the substance at issue in this PMN

would be sent for disposal, while the proposed use of the

PMN substance would be to produce a "petroleum-like"

substance which could be blended with normal petroleum to

produce a commercial-scale petrochemical feedstock, thus

reducing the need for imported oil and thus contributing

to U.S. domestic oil sourcing and security.

OTHER USES: is used as boiler fuel for

steam generation, fungicide for wood preservative, and

crude feedstock for physical/chemical. 

is used as boiler fuel for steam generation, and crude

feedstock for physical/chemical. is used

as a non-dispersive solvent component of a refractive

maintenance ramming paste used to form pintle in a

smelting furnace and a non-dispersive solvent component

of a refractive maintenance ramming paste used to repair

cracks, fissures, and spalling in refractory of a

smelting furance.

MSDS: Yes Label: No

Gen Eqpt: impervious gloves: viton neoprene, PVC/ goggles

and/or face shield

Respirator: if engineering and administrative controls

cannot maintain levels below suitable exposure limits, a

chemical cartridge with an organic vapor with dust/mist

prefilter, or supplied air or continuous flow powered air

purifying with organic vapor cartridge and a dust/mist

prefilter can be used/ self-contained breathing apparatus

with full facepiece operated in pressure demand or other

positive pressure mode/ supplied airline operated in

pressure demand or other positive pressure with an

auxiliary self-contained breathing apparatus operated in

pressure demand or other positive pressure mode

Health Effects: many components are both toxic and

carcinogenic/ flammable| EYE CONTACT: this material has a

strong corrosive effect on the eyes/ vapors may irritate

the eyes/ direct contact with the eye may result in mild

NOTES & KEY ASSUMPTIONS:

Generated by the 06/07/2005 version of ChemSTEER. This

PMN is for a refinery feed material (80% of PV) and a

catalytic cracker raw material (20% of PV). The uses are

similar (the PMN is destroyed as it's refined into other

components). Therefore, one assessment use assessment

for the full PV was made. The submitter was called but

was unavailable; see contact report. // SAT concerns

were for inhalation, dermal, drinking water and all

releases to water. The PMN's PBT rating is P2B2T2.

Therefore, a full assessment was completed. This is an

exposure-based review for eco only, per SAT. // MSDS

provided a list of chemicals in the mixture and their

OSHA PELs. However % of the chemical in the PMN was not

provided for many of the substances and the MSDS notes

the mixture can vary from day to day. Therefore, %

concentration of given chemicals in the PMN were not

provided in this IRER. 

All other cases used standard

CEB models or submission estimates (consistent with this

IRER). // All past cases assessed MFG and USE of the

PMN as refinery/cat cracker feed (consistent with this

IRER). All past cases assessed air releases during MFG

(consistent with this IRER). 

assessed equipment cleaning for 1 d/yr for storage tank

(consistent with this IRER). assessed

equipment cleaning wastes to incineration or landfill

based on techncial contact. This IRER also assumes

releases to incineration or landfill as the type of

mixture would typicall preclude companies from releasing

to water. All past cases assessed inhalation to vapors

and dermal exposures to liquids per SAT requirements

(consistent with this IRER). For USE, 

 assessed air releases and transport container

releases (consistent with this IRER). assessed

air releases and equipment cleaning (1 d/yr) releases

(consistent with this IRER). assessed

2 Release activities are from engineering report's Manufacturing (Mfg), Processing (Proc) and Use release activity 

labels. Multiple release activities are combined in one exposure scenario if their releases occur at same location. 

3 Exposure calculations are Acute Dose Rate (ADR), Lifetime Average Daily Dose (LADD), and Probabilistic 

Dilution Model (PDM). There may be one, two, or all three exposure calculations per exposure scenario. 

 CC is the aquatic concentration of concern. 

4 This column displays concentration values for the 7Q10 streamflow, which is defined as the average daily
