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.

OCCUPATIONAL EXPOSURE RATING: 2-3B

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

### 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.

Multiple release activities are combined in one expo sure 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 streamflow of the seven consecutive days of lowest flow within a ten year period.
