NOTES & KEY ASSUMPTIONS: 

Generated by the 06/07/2005 version of ChemSTEER. This IRER is for the consolidated set of 

chemicals P06-0263/264/266/267. The production volume for each chemical is 236,000 kg/yr and 

all estimates are for each PMN (not a combination). A separate IRER has been completed for 

these chemicals. Any changes to this IRER may effect the other IRER. 

 P06-0263/264/266/267 are used as a hydrate inhibitor in oil 

and gas well applications. Three same submitter/same use past

case referenced for consistency are: . Inhalation exposure was negligible in all three past cases 

(consistent with this IRER). All three reference the 

Generic Scenario for Oil Well Treatment Chemicals for some end use information (consistent with 

this IRER). Water release are expected from at the use sites in (not consistent with this IRER). 

to the manufacturing site in (consistent with this IRER per submission information).
