Gen Eqpt: protective gloves: Nitrile rubber or butyl rubber/ tightly 

fitting safety goggles/ face shield and protective suit for abnormal 

processing problems/ provide an effective exhaust ventilation system

approved filter/ wear full face mask supplied with: Combination filter: 

ABEKP

Physical State and Misc CRSS Info: 

MW: 304.00 %<500 %<1000

VP: 1.0E-6 torr @ 

Neat: Solid (est.) Mfg: Dispersion: 0.05-0.5% PMN substance in aqueous 

formulation with other amine chloride salts Proc/Form: Dispersion: 

0.02-0.2% PMN substance in asphalt emulsion End Use: Solid: PMN 

substance entrained in road asphalt. Submitted Data: None. The measured 

MP of 21°C and BP of 335°C on PMN p.13 are for the precursor oleylamine. 

The estimated values on PMN p.13 also appear to be for oleylamine. 

Estimated Data: VP < 0.000001 torr (salt); WS = dispersible (use and 

structure).Estimated Data (EPI with no MP entered, for hydrochloride 

covalent ion pair): BP = 495.08°C; VP = 3.94E-10 torr; WS = 0.00243 g/L; 

log P = 4.31.

Number of Sites/ Location: 1 

Days/yr: 20

Basis: Submission states 1 site, up to 90.7 kg/bt, 2.5 hr/bt, 20 bt/yr.

Process Description: Raw materials added to batch tank -> heated to 50 

deg C -> PMN forms (0.5% liquid PMN) -> held until asphalt blending step 

per 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.

Water or Incineration or Landfill

Conservative: 4.6E-1 kg/site-day over 1 day/yr from 1 site

or 4.6E-1 kg/site-yr from 1 site or 4.6E-1 kg/yr-all sites

to: Uncertain

from: Equipment Cleaning Losses of Liquids from a Single, Small Vessel

basis: EPA/OPPT Single Vessel Residual Model, CEB standard 1% residual. 

Submission states equipment is not cleaned between batches. EPA 

assumes one cleaning per year.

RELEASE TOTAL

4.6E-1 kg/yr - all sites

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 3

Basis: Submission estimates 2 workers potentially exposed. EPA assumes 

minimum default of 3 workers per site.

Number of Sites/ Location: 1 

Days/yr: 91

Basis: Submisison states 1 site, 10-50 kg PMN. ChemSTEER calculates 

91 bt/yr.

Process Description: PMN in emulsion (0.5% liquid) -> hard piped to 

colloidal mill -> blended with asphalt -> cooled -> sent to asphalt 

emulsion tank (0.02-0.2% PMN)

PMN: 15-0671 

Use: Asphalt Use

unknown paving sites 

Number of Sites/ Location: 729 

Days/yr: 250

Basis: Submission states 0.2-4 g PMN used/site. Past cases estimate 

250 d/yr (EPA default). Using 4 g (0.004 kg), ChemSTEER calculates 729 

sites.

Process Description: Asphalt formulation (dispersion, 0.02 - 0.2%) 

transported to road construction site -> transfer to road paving 

equipment -> asphalt applied to road -> PMN entrained in cured asphalt 

(per submission and CRSS)

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: 

Based on information from past case P14-0089c: no releases are expected 

from "Cleaning Liquid Residuals from Tank Trucks Used to Transport the 

Raw Material". Standard industry practices do not undertake tank truck 

cleaning operations; this is substantiated with support letters from 

trucking companies. EPA also did not assess equipment cleaning releases 

because the submission states that once the PMN is incorporated into 

the asphalt emulsion, the PMN substance is becomes a part of the asphalt 

itself.
