 NAVG = 448 with 95% <500 and 100% <1000 (GPC, spectrum

not provided). The MW of the structure as drawn with n=1

is 448. The submitter states that for 75-85% of the PMN

substance n = 1-4 with the remainder n>4. MSDS is

provided for a >90% solution of PMN substance in

unreacted feedstock. Submitted data: none. Estimated data

(EPI for structure as drawn with n=1 and mp entered as

20°C): bp 443°C, vp = 7.18E-7 torr. The PMN substance is

expected to react with water. Alkoxysilane FGEW (3 EtO-Si,

Testing (No Testing desired)

OCCUPATIONAL EXPOSURE RATING: 1A

NOTES & KEY ASSUMPTIONS:

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

Synthetic sequence --> P08-0722. The submitter

was contacted for additional information, see contact

report. (Note: The submitter will fax in an amendment to

correct the PV) This IRER assessed releases and exposures

to PMN during manufacturing and use as surface (5%) or

pigment treatment (95%). The PMN may be used for two

different purposes, but both processes have similar

operation where the PMN is incorporated onto inorganic

particles. Therefore, only a single use operation is

assessed. For manufacturing, releases were assessed to

incineration, per submission. For use, uncertain releases

were assessed to incineration (submitter estimate) and

water (worst case) due to SAT concern for water release.

Note for incineration, PV << 200,000 kg/yr. Release to

land is not required, and fugitive air release is

expected to be negligible. Dermal exposure was assessed

for both operations. Inhalation exposure is expected to

be negligible, as VP << 0.01 torr. 

 

POLLUTION PREVENTION CONSIDERATIONS:

None.

EXPOSURE-BASED REVIEW: No

Number of Sites/ Location: 1

Gelest, Inc Morrisville PA 19067

Days/yr: 10

Basis: Submission states 100% PMN in product, 10

batches/yr and 2,500 kg/batch. For a total of 1

manufacturing sites, (Per fax letter 3/15/2011)

Process Description: Reactants --> Reaction Vessel -->

Strip --> 100% PMN liquid packaged in steel drums or

totes (technical contact, submission)

ENVIRONMENTAL RELEASES ESTIMATE SUMMARY

IRER Note: The daily releases listed for any source below

may coincide with daily releases from the other sources

to the same medium. Note for incineration, PV << 200,000

kg/yr. Release to water is not expected per submission.

Release to land is not required, per SAT. Fugitive air

release is expected to be negligible, as VP << 0.01 torr.

Incineration

Conservative: 2.5E+1 kg/site-day over 10 days/yr from 1

site

or 2.5E+2 kg/yr

basis: EPA/OPPT Single Vessel Residual Model, CEB

standard 1% residual. Submission estimates up to 0.

2kg/batch PMN (<< 0.01%) may be incinerated off-site. CEB

default of 1% residual is assessed as conservative.

Days/yr: 250

Basis: Submission indicates 1 use site and 100% PMN

Process Description: 100% liquid PMN unloaded from totes

or drums --> blender or roll mills, PMN deposited onto

surfaces of inorganic particles --> PMN destroyed, per

CRSS. Inorganic particles packaged. (submission,

ENVIRONMENTAL RELEASES ESTIMATE SUMMARY

IRER Note: The daily releases listed for any source below

may coincide with daily releases from the other sources

to the same medium. Note for incineration, PV << 200,000

kg/yr. Release to land is not required, per SAT. Fugitive

air release is expected to be negligible as VP << 0.01

torr. Technical contact estimates releases to off-site

inceration, however, due to uncertainties at

non-submitter controlled site, releases are assessed to

incineration or water due to SAT concern for water

release.

Incineration

High End: 6.2E+0 kg/site-day over 120 days/yr from 1 site

or 7.5E+2 kg/yr

to: uncertain

from: Cleaning Liquid Residuals from Drums Used to

Transport the Raw Material

basis: EPA/OPPT Drum Residual Model, CEB standard 3%

residual. Technical contact indicates totes are shipped

back to the submitter site and reused, resulting in no

releases. However, drum residues may be incinerated. Due

to uncertainties, CEB assesses release to incineration or

water due to SAT concern for water release. Based on a

fax Oct/27, the totes are either returned for refilling

with same chemical or incinerated.

Incineration or Landfill

Conservative: 1.0E+0 kg/site-day over 250 days/yr from 1

site

or 2.5E+2 kg/yr

to: uncertain

from: Equipment Cleaning Losses of Liquids from a Single,

Large Vessel

basis: EPA/OPPT Single Vessel Residual Model, CEB

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 3
