Revision Notes / Assessment Overview: This version is the

CEB Reviewed version.| | On February 7, 2012, the U.S.

Environmental Protection Agency (EPA) and the U.S.

Department of Justice announed a settlement agreement

with Dover Chemical Corporation resulting from the

unauthorized manufacture of chemical substances at

facilities in Dover, Ohio and Hammond, Indiana. As a

result of the settlement, EPA has recieved several

premanufacure notices (PMN) from Dover Chemical

Corporation for various existing medium-chain and

long-chain chlorinated paraffin (MCCP and LCCP) products.

The review of these PMNs is complimented by EPA's current

initiative to conduct a review of the environmental and

health impacts of MCCPs and LCCPs as part of EPA's Work

Plan Chemicals Initiative. /// For each substance, Dover

Chemical has provided detailed information for the

manufacturing and downstream processing and use as part

of the PMN submissions. Prior to recieving the

submissions, EPA conducted a literature review on release

and exposure data for the manufacture and downstream

processing and use of chloriated paraffins as a means to

supplement information provided by Dover Chemical and/or

fill any data gaps that may exist. Literature sources

that have been reviewed include: 1) previous EPA

assessments on chlorinated paraffins; 2) foreign risk

assessments on MCCPs and LCCPs (e.g. EU risk assessments);

3) EPA/OPPT Generic Scenarios; 4) OECD Emission Scenario

Documents; and 5) Toxics Release Inventory data. Data

provided by Dover Chemical, data identified in the

literature review, and EPA/OPPT standard models were

reviewed and the best available data were used to

assesses environmental releases and occupations exposures.

SUBMITTER: Dover Chemical

USE: Generic uses MCCP: 1) Forty-three percent of the

notification substances are used as a flame

retardant/plasticizer in polymers. Typical

concentration in the plastic is 12-30%. 2) Thirty

percent of the notification substance is used as a

lubricant in metal working fluids (MWFs). The

notification substance is blended into the MWFs at 5-10%.

3) Two percent of the notification substances is used as

lubricants in automotives. The notification substance is

blended into the lubricant at 4%. [20% consumer uses].

4) Twenty-four percent of the notification substance is

used as a flame retardant/plasticizer in rubber. Typical
Page 2 of 46

total concentration of flame retardant/plasticizer in

the rubber is 1-10%, with a median value of 5.5%. 5)

One-half of one percent of the notification substances

are used as a plasticizer in solvent based paints,

adhesives and sealants. The paints are specialty paints

for applications where weather resistant coatings are

needed, such as steel construction, industrial flooring,

road marking, and swimming pools. The notification

substance is blended into the paints at 5-15%. [0.1%

consumer use as sealants in windows] and 6) One-half of

one percent of the notification substances are applied as

a flame retardants/waterproofers to textiles. The

notification substance products are added at 5% of the

textile coating finishing solution.

NOTES & KEY ASSUMPTIONS:

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

PMN is a MCCP product that is manufactured domestically

and used in the following applications: 1) 43% as a

flame retardant/plasticizer in polymers. 2) 30% as a

lubricant in metal working fluids (MWFs). 3) 2% used as

lubricant in automotive engines (20% consumer, 80%

commerical) 4) 24% as a flame retardant/plasticizer in

rubber 5) 0.5% as a plasticizer in solvent based paints,

adhesives and sealants and 6) 0.5% as a flame

retardants/waterproofers to textiles. // Note, the SAT

information is not yet avaiable for this PMN. // For MFG:

Submitter estimates were used for assessing releases and

dermal exposure was assessed using standard models. //

For downstream processing and use operations: The

releases estimates were based on a combination of

submitter provided data and data available in various

literature sources. The literature sources include those

previous review by EPA as well as Generic Scenarios and

Emission Scenario Documents. The submitter has stated

that "Due to the large number of customers and potential

sites where the notification substances may be used,

specific use information for each site could not be

obtained. Rather, these worker exposures and

environmental releases scenarios are average scenarios

for each particular use." Due to the uncertainty at

multiple downstream use sites, the most conservative data

were chosen when evaluating releases for downstream

operations. // Note, all exposure-based criteria were met.

Basis: Per submission, 2 submitter sites, 93 bt/yr, 25.5

hr/bt, 20,412 kg/bt, PMN produced as a liquid at 91.5 to

100%. CEB assumes PMN is produced as liquid at 100% to

conservatively assess exposures.

Process Description: 1-tetradecene charged to a reactor

at approximately 176 deg C ---> chlorine gas in fed to

reactor ---> QC sampling to check reaction completion

(PMN liquid, 91.5 - 100%) ---> off-gas is fed through

scrubber system --> when reaction is finished, turn off

chlorine ---> nitrogen purge ---> residual hydrochloric

acid is removed from the product by nitrogen blow, then

air blow ---> mix with stabilizer, antifoaming agent, and

amine phosphate ester salt ---> charge to storage tank

(optional) ---> PMN (liquid, 91.5 - 100%) is charged to

tanks trucks (69% of PV), drums (23% of PV), totes (4% of

PV), and railcars (4% of PV) (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. The submission provides releases

estimates for filter disposal and equipment cleaning.

Filter disposal releases are expected to landfill while

equipment cleaning releases are expected to incineration

or landfill. The equipment cleaning releases were

estimated by the submitter to be 2% of the total PV which

is equivalent to the CEB standard model loss rate. Filter

disposal was estimated by the submitter to account for 0.

011% of the total PV.

Incineration or Landfill

Conservative: 4.1E+2 kg/site-day over 1 day/yr from 2

sites

or 8.2E+2 kg/yr

to: incineration or landfill (submission)

from: Equipment Cleaning Losses of Liquids from Multiple

Vessels

basis: EPA/OPPT Multiple Process Vessel Residual Model,

CEB standard 2% residual. The submission estimates 408.24

kg/bt of PMN are released to incineration or landfill

from equipment cleaning residuals with cleaning occuring

once per year. This is equivalent to a loss rate of 2%

which is the same as the standard model loss fraction.

CEB assesses equipment cleaning residual releases to
Page 6 of 46

incineration or landfill using a loss rate of 2%.

Landfill

Output 2: 2.2E+0 kg/site-day over 93 days/yr from 2 sites

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 8

Basis: The submission estimates up to 4 workers/site

exposed to PMN at during various activities. As

conservative, CEB assesses dermal exposure for all

workers to liquid PMN at 100% during sampling (1-hand)

and loading (2-hand) activities.

Basis: Per submission, 32 plastic compounding sites, 60

days/yr of operation, PMN used as a liquid at 91.5 to

100% and compounded to 12-30% in solid plastic pellets.

CEB assumes 100% PMN in raw material and 30% PMN in

plastic product to conservatively assesses exposures. CS

calculates a use rate of 846.4 kg/site-bt.

Process Description: PMN (liquid, 91.5 - 100%) is

unloaded from tanks trucks (69% of PV), drums (23% of PV),

totes (4% of PV), and railcars (4% of PV) into feeder

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. The releases estimates were based on

a combination of submitter provided data and data

available in various literature sources. A description of

the data is provided in the release notes for each source.

The submitter has stated that "Due to the large number

of customers and potential sites where the notification

substances may be used, specific use information for each

site could not be obtained. Rather, these worker

exposures and environmental releases scenarios are

average scenarios for each particular use." Due to the

uncertainty at multiple downstream use sites, the most

conservative data was chosen when evaluating releases for

downstream operations.

Water

Output 2: 8.5E-3 kg/site-day over 60 days/yr from 32 sites

to: water or air (GS, ESD)

from: Fugitive Air Emissions During High Temperature

Extrusion

basis: User-Defined Loss Rate Model. The submission does

not address fugitive air emissions from the high

temperature extrusion process. Both the 2004 GS and ESD

for Plastics Compounding estimates a loss rate of 0.002%

to fugitive air for low volatility substances which would

include MCCP substances. 50% of the releases are expected

to remain in the air while the other 50% is expected to
Page 8 of 46

be released to water.

Water or Incineration

Output 1: 1.7E+1 kg/site-day over 60 days/yr from 32 sites

or 3.3E+4 kg/yr

to: water or incineration (submission, GS)

from: Equipment Cleaning Losses of Liquids from

Compounding Equipment

basis: User-Defined Loss Rate Model. The submission

esitmates 16.9 kg/day (16.9/846 = 2% of PV) released to

incineration from equipment cleaning residuals with

cleaning occuring 1 day/yr. The 2004 GS for Plastics

Compounding estimates a loss rate of 2% based on the

EPA/OPPT Multiple Vessel Residual model with releases to

water. Due to uncertainty at multiple downstream release

sites, a 2% loss rate is used for for equipment cleaning

residual releases with releases assessed to water or

incineration occuring once per day.

Water or Incineration or Landfill

Output 1: 6.2E+0 kg/site-day over 56 days/yr from 32 sites

or 1.1E+4 kg/yr

to: water, incineration, or landfill (submission, GS)

from: Cleaning Liquid Residuals from Drums Used to

Transport the Raw Material

basis: User-Defined Loss Rate Model. The submission

esitmates 25.4 kg/day (25.4/846 = 3% of PV) released to

landfill from drum residual disposal. The 2004 GS for

Plastics Compounding estimates a loss rate of 3% based on

the EPA/OPPT Drum Residual model with releases to water,

incineration, or landfill. Due to uncertainty at multiple

downstream release sites, a 3% loss rate is used for drum

residual releases with releases assessed to water,

incineration, or landfill.

Water or Incineration or Landfill

Output 1: 4.2E+0 kg/site-day over 19 days/yr from 32 sites

or 2.5E+3 kg/yr

to: water, incineration, or landfill (submission, GS)

from: Cleaning Liquid Residuals from Rail Cars, Tank

Trucks, and Totes Used to Transport the Raw Material

basis: User-Defined Loss Rate Model. The submission

esitmates 1.7 kg/day (1.7/846 = 0.2% of PV) released to

landfill from railcar, tank truck, and tote residual

disposal. The EPA/OPPT Bulk Transport Residual Model

estimates a loss rate of 0.2%. The 2004 GS for Plastics

Compounding estimates transport container residual

releases to water, incineration, or landfill. Due to

uncertainty at multiple downstream release sites, a 0.2%

loss rate is used for drum residual releases with

releases assessed to water, incineration, or landfill.

Water or Incineration or Landfill

Suggested Value: 8.5E-2 kg/site-day over 60 days/yr from
Page 9 of 46

32 sites

or 1.6E+2 kg/yr

to: water, incineration, or landfill (ESD, 1992 RM-2,

2002 EU RA)

from: Spillage During Raw Material Handling

basis: User-Defined Loss Rate Model. The submission does

not address potential releases from spillage during raw

material handling. A 1992 RM-2 assessment for SCCPs

estimated these releases to be 0.1% of the PV with 90% of

releases going to incineration landfill and 10% going to

water. the 2004 ESD for Plastics Compounding as well as a

2002 EU Risk assessment on MCCPs estimated these releases

to be 0.01% of PV with releases to water or solid waste.

The estimate from the 2004 ESD and the 2002 EU Risk

Assessment orginate from more recent data sources and is

therefore used as the basis for estimating releases.

Air

Output 2: 8.5E-3 kg/site-day over 60 days/yr from 32 sites

to: water or air (GS, ESD)

from: Fugitive Air Emissions During High Temperature

Extrusion

basis: User-Defined Loss Rate Model. The submission does

not address fugitive air emissions from the high

temperature extrusion process. Both the 2004 GS and ESD

for Plastics Compounding estimates a loss rate of 0.002%

to fugitive air for low volatility substances which would

include MCCP substances. 50% of the releases are expected

to remain in the air while the other 50% is expected to

be released to water.

RELEASE TOTAL

4.6E+4 kg/yr - all sites

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 768

Basis: The submission estimates up to 3 workers/site. The

GS for Plastics Compounding estimates 24 workers/site. As

conservative, 24 workers/site is estimated due to

multiple downstream sites.

Inhalation:

Exposure to Particulate (Class I)

Low End of Range: 3.0E-2 mg/day over 60 days/yr

High End of Range: 4.4E+0 mg/day over 60 days/yr

Number of workers (all sites) with inhalation exposure:

Basis: Fugitive Air Emissions During High Temperature

Extrusion; User-defined Inhalation Model. A 2008 EU Risk

Assessment on MCCP contains monitoring data from plastic

compounding operations is the EU. The monitoring data is

based on 32 air samples from 4 sites. Results showed air

concentrations ranging from <0.003 to 0.44 mg/m3 with a
Page 10 of 46

median of 0.03 mg/m3 and a 90th percentile of 0.15 mg/m3.

Exposures estimates are presented based on the low and

high of the range for these data.

NOTE: The respirator class is: I. Particulate (including

solid or liquid droplets).

INHALATION MONITORING DATA REVIEW

1) Uncertainty (estimate based on model, regulatory limit

 or data not specific to industry): Yes

2)a) Exposure level > 1 mg/day? Yes

 OR

 b) Hazard Rating for health of 2 or greater? No

Inhalation Monitoring Data Desired? Yes (both criteria

met)

Dermal:

Only dermal exposure to liquid PMN during unloading is

assessed. PMN will be encapsulated in plastic pellets

during handling of plastic pellet product. While some

surface contact may occur, dermal exposure to solids in

this form are non-quantifiable (2004 ESD; Cast Solids,

CEB Method for Screening-Level Assessments of Dermal

Exposure).

Exposure to Liquid at 100.00% concentration

High End: 1.8E+3 mg/day over 60 days/yr

INITIAL REVIEW ENGINEERING REPORT 

PMN: 12-0283

USE1: Plastics Converting (43% of PV)

Number of Sites/ Location: 32

unknown sites

Days/yr: 250

Basis: The submission does not provide information on

plastic converting. Per submission, the upstream

compounding process yields plastic pellets containing 12

- 30% (median 21%) PMN. CEB assumes 30% as conservative

for expsoures. The 2004 GS for Plastics Converting is

referenced to estimate general facility estimates. The GS

assumes 250 days/yr of operation. Based on literaure data,

PVC is the most common plastic in which CPs are used as

flame retardants and plasticizers. Using annual

production volume of PVC from the GS, the use rate is

calculated as: 6,680,000,000 kg plastic/yr / 12,191 total

sites / 250 days/yr x 0.12 = 18,265 kg/site-day. based on

this use rate, CS calculates 1 end use site. Since the

calculated number of end use sites < number of upstream

processing sites, CEB assumes 1 customer per compounding

sites, or 32 convering sites. CS calcualtes an adjusted

use rate of 203.14 kg/site-day.

Process Description: Plastic pellets or other solid form

containing PMN (solid, 12-30%) are unloaded ---> forming

(heating) ---> molding and shaping using various

processes (injection molding, extrusion, casting,

calendaring, etc.) ---> trimming ---> finishing ---> 

finishing plastic article (ESD)

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. The submission does not address the

potential for plastics converting operations after

compounding into plastic pellets. The technical contact

indicated that these operations were considered but

estimates were not provided due to lack of information on

downstream processes after compounding. The releases

estimates are based data available in various literature

sources. A description of the data is provided in the

release notes for each source. Due to the uncertainty at

multiple downstream use sites, the most conservative data

were chosen when evaluating releases for downstream

operations.

Water

Suggested Estimate: 1.5E-1 kg/site-day over 250 days/yr

from 32 sites

to: water or air (ESD, 2010 EU CSR)

from: Fugitive Air Emissions During Forming and Molding
Page 12 of 46

basis: User-Defined Loss Rate Model. The submission does

not address plastic converting operations. Data from

various literature sources suggests that fugitive air

emissions generated during forming and molding can range

between 0.002 to 0.15% with engineering controls

depending on the type of coversion process (e.g.

extrusion, injection molding, calendaring). The 2004 ESD

for Plastics Converting estimates that 50% of air

emissions will settle and be ultimately released to water

while the other 50% remains in air. As conservative, CEB

assesses fugitive air emissions at a loss rate of 0.15%

with 50% to water and 50% to air.

Water or Incineration or Landfill

Suggested Estimate: 2.0E-2 kg/site-day over 250 days/yr

from 32 sites

or 1.6E+2 kg/yr

to: water, incineration, or landfill (RM-2)

from: Spillage During Raw Material Handling

basis: User-Defined Loss Rate Model. The submission does

not address plastic converting operations. A 1992 RM-2

assessment for SCCPs estimated releases from spills to be

0.1% of the PV with 90% of releases going to incineration

landfill and 10% going to water. A 2010 EU CSR assessment

on MCCPs estimated these releases to be 0.01% of PV with

releases to water or solid waste. The 2010 EU CSR

estimate is derived from more recent data sources and is

therefore used as a basis to estimate releases from

spillage.

Water or Incineration or Landfill

Output 2: 2.0E+0 kg/site-day over 250 days/yr from 32

sites

or 1.6E+4 kg/yr

to: water, incineration, or landfill (GS)

from: Cleaning Solid/ Powder Residuals from Containers

Used to Transport the Raw Material

basis: EPA/OPPT Solid Residuals in Transport Containers

Model, CEB standard 1% residual. The submission does not

address plastic converting operations. The 2004 ESD for

Plastics Converting estimates releases from containiner

cleaning using the EPA/OPPT model for solid residuals

with releases to water, incineration, or landfill.

Water or Incineration or Landfill

Conservative: 4.1E+0 kg/site-day over 250 days/yr from 32

sites

or 3.3E+4 kg/yr

to: water, incineration, or landfill (ESD)

from: Equipment Cleaning Losses from Multiple Vessels

basis: EPA/OPPT Multiple Process Vessel Residual Model,

CEB standard 2% residual. The submission does not address

plastic converting operations. The 2004 ESD for Plastics

Converting estimates releases from equipment cleaning
Page 13 of 46

using the EPA/OPPT model loss rate of 2% with releases to

water, incineration, or landfill.

Water or Landfill

Suggested Estimate: 5.1E+0 kg/site-day over 250 days/yr

from 32 sites

or 4.1E+4 kg/yr

to: water or landfill (ESD)

from: Scrap Material

basis: User-Defined Loss Rate Model. The submission does

not address plastic converting operations. A 1992 RM-2

assessment for SCCPs estimated scrap from trimming to be

1% of the PV with 90% of releases going to landfill. The

2004 ESD for Plastics Converting estimated these releases

to be 2.5% of PV with releases to water or landfill. This

is based on the assumption that large pieces of scrap

material will be disposed to landfill via solid waste and

dust generated during trimming will settle to the floor

and be washed away to wastewater during cleaning. Due to

multiple unknown downstream sites, CEB conservatively

assesses a 2.5% loss rate with releases to water or

landfill based on the ESD.

Air

Suggested Estimate: 1.5E-1 kg/site-day over 250 days/yr

from 32 sites

to: water or air (ESD, 2010 EU CSR)

from: Fugitive Air Emissions During Forming and Molding

basis: User-Defined Loss Rate Model. The submission does

not address plastic converting operations. Data from

various literature sources suggests that fugitive air

emissions generated during forming and molding can range

between 0.002 to 0.15% with engineering controls

depending on the type of coversion process (e.g.

extrusion, injection molding, calendaring). The 2004 ESD

for Plastics Converting estimates that 50% of air

emissions will settle and be ultimately released to water

while the other 50% remains in air. As conservative, CEB

assesses fugitive air emissions at a loss rate of 0.15%

with 50% to water and 50% to air.

Air

Output 2: 4.6E-2 kg/site-day over 250 days/yr from 32

sites

to: air or landfill w/ 99% dust collection efficiency

(RM-2)

from: Dust Generation During Trimming

basis: User-Defined Loss Rate Model. The submission does

not address plastic converting operations. A 1992 RM-2

Assessment of SCCPs estimates a loss rate of 75g/kg of

plastic produced with 1% of releases to air and 99% to

landfill based on a 99% dust collection efficiency. Based

on a MCCP concentration of 30%, the loss rate for PMN

during plastic converting is 75g/kg of plastic x 0.3 = 22.
Page 14 of 46

5g/kg of plastic, or 2.25%.

Landfill

Output 2: 4.5E+0 kg/site-day over 250 days/yr from 32

sites

or 3.6E+4 kg/yr

to: air or landfill w/ 99% dust collection efficiency

(RM-2)

from: Dust Generation During Trimming

basis: User-Defined Loss Rate Model. The submission does

not address plastic converting operations. A 1992 RM-2

Assessment of SCCPs estimates a loss rate of 75g/kg of

plastic produced with 1% of releases to air and 99% to

landfill based on a 99% dust collection efficiency. Based

on a MCCP concentration of 30%, the loss rate for PMN

during plastic converting is 75g/kg of plastic x 0.3 = 22.

5g/kg of plastic, or 2.25%.

RELEASE TOTAL

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 1,536

Basis: The submission does not address converting

processes. The 2004 ESD for Plastic Converting estimates

up to 48 workers/site.

Inhalation:

Exposure to Particulate (Class I)

2008 EU RA Data: 1.2E+1 mg/day over 250 days/yr

OSHA PEL: 4.5E+1 mg/day over 250 days/yr

Number of workers (all sites) with inhalation exposure: 1,

Basis: Inhalation Exposure During Converting Process;

User-defined Inhalation Model. A 2008 EU RA on MCCPs and

a 2010 EU CSR on MCCPs contains monitoring data from PVC

converting operations is the EU. The monitoring data

suggest MCCP air concentrations ranging from <0.01 to 1.2

mg/m3 depending on the type of converting process. These

data are based on a over 28 samples taken from 4 sites.

It is unknown whether these data represent area or

personal monitoring data. The 2004 ESD for Plastics

Converting estimates exposures during converting using

the OSHA PEL Limiting Model. Based on uncertainty in

multiple downstream use sites and the fact that these

data are only basd on 1 site, CEB assesses exposures

based on the high end of the EU data range (1.2 mg/m3)

and the OSHA PEL (15 mg/m3 x 0.3 = 4.5 mg/m3).

NOTE: The respirator class is: I. Particulate (including

solid or liquid droplets).

INHALATION MONITORING DATA REVIEW

1) Uncertainty (estimate based on model, regulatory limit

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. The releases estimates were based on

a combination of submitter provided data and data

available in various literature sources. A description of

the data is provided in the release notes for each source.

The submitter has stated that "Due to the large number

of customers and potential sites where the notification

substances may be used, specific use information for each

site could not be obtained. Rather, these worker

exposures and environmental releases scenarios are

average scenarios for each particular use." Due to the

uncertainty at multiple downstream use sites, the most

conservative data was chosen when evaluating releases for

downstream operations.

basis: User-Defined Loss Rate Model. The submission does

not address fugitive air emissions from the high

temperature extrusion process. Both the 2004 GS and ESD

for Plastics Compounding estimates a loss rate of 0.002%

to fugitive air for low volatility substances which would

include MCCP substances. 50% of the releases are expected

to remain in the air while the other 50% is expected to

be released to water.

basis: EPA/OPPT Drum Residual Model. The submission

esitmates 6.4 kg/day (6.4/886.6 = 0.72% of PV) released

to incineration or landfill from drum residual disposal.

The 2004 GS for Plastics Compounding estimates a loss

rate of 3% based on the EPA/OPPT Drum Residual model with

releases to water, incineration, or landfill. Due to

uncertainty at multiple downstream release sites, the

EPA/OPPT model is used as a conservative estimate for

drum residual releases with releases assessed to water,

incineration, or landfill. /// CEB NOTE: The submitter

estimate based on a loss rate of 0.72% is also presented

to provide a range of estimates.

kg/day (1.35/886.6 = 0.15%% of PV) released to

incineration or landfill from railcar, tank truck, and

tote residual disposal. The EPA/OPPT Bulk Transport

Residual Model estimates a loss rate of 0.2%. The 2004 GS

for Plastics Compounding estimates transport container

residual releases to water, incineration, or landfill.

Due to uncertainty at multiple downstream release sites,

the EPA/OPPT model is used as a conservative estimate for

bulk container residual releases with releases assessed

to water, incineration, or landfill. /// CEB NOTE: The

submitter estimate based on a loss rate of 0.15% is also

presented to provide a range of estimates.

basis: EPA/OPPT Multiple Process Vessel Residual Model.

The submission esitmates 17.8 kg/day (17.8/890.13 = 2% of

PV) released to incineration or landfill from equipment

cleaning residuals with cleaning occuring 1 day/yr. The

2004 GS for Plastics Compounding estimates a loss rate of

2% based on the EPA/OPPT Multiple Vessel Residual model

with releases to water. A loss rate of 2% is used. Due to

uncertainty at multiple downstream release sites,

releases are assessed to water, incineration, or landfill

occuring once per day.

Water or Incineration or Landfill

Suggested Estimate: 8.9E-2 kg/site-day over 31 days/yr

from 33 sites

or 9.1E+1 kg/yr

to: water, incineration, or landfill (ESD, 1992 RM-2,

2002 EU RA)

from: Spillage During Raw Material Handling

basis: User-Defined Loss Rate Model. The submission does

not address potential releases from spillage during raw

material handling. A 1992 RM-2 assessment for SCCPs

estimated these releases to be 0.1% of the PV with 90% of

releases going to incineration landfill and 10% going to

water. the 2004 ESD for Plastics Compounding as well as a

2002 EU Risk assessment on MCCPs estimated these releases

to be 0.01% of PV with releases to water or solid waste.

The estimate from the 2004 ESD and the 2002 EU Risk

Assessment orginate from more recent data sources and is

therefore used as the basis for estimating releases.

Basis: The submission does not provide information on

rubber converting. Per submission, the upstream

compounding process yields rubber sheets containing 1 - 

10% (median 5.5%) PMN. CEB assumes 10% as conservative

for expsoures and 250 days/yr based on 2004 ESD for

Plastic Converting. Calculation using the 2004 ESD yields

the number of end use sites < number of upstream

processing sites. Therefore, CEB assumes 1 customer per

compounding sites, or 33 convering sites. CS calcualtes

an adjusted use rate of 109.94 kg/site-day.

Process Description: Rubber sheets or other solid form

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. The submission does not address the

potential for rubber converting operations after

compounding into rubber sheets.The technical contact

indicated that these operations were considered but

estimates were not provided due to lack of information on

downstream processes after compounding. The releases

estimates are based data available in various literature

sources. A description of the data is provided in the

release notes for each source. Due to the uncertainty at

multiple downstream use sites, the most conservative data

were chosen when evaluating releases for downstream

operations.

Water

Suggested Estimate: 2.7E-1 kg/site-day over 250 days/yr

from 33 sites

to: water or air (ESD, 2010 EU CSR)

from: Fugitive Air Emission During Forming and Molding

basis: User-Defined Loss Rate Model. The submission does

not address rubber converting operations. Data from

various literature sources suggests that fugitive air

emissions generated during rubber converting can range

between 0.002 to 0.05% with engineering controls

depending on the type of coversion process (e.g.

extrusion, injection molding, calendaring). The 2004 ESD
Page 21 of 46

for Plastics Converting estimates that 50% of air

emissions will settle and be ultimately released to water

while the other 50% remains in air. As conservative, CEB

assesses fugitive air emissions at a loss rate of 0.05%

with 50% to water and 50% to air.

Water or Incineration or Landfill

Suggested Estimate: 1.1E-2 kg/site-day over 250 days/yr

from 33 sites

or 9.1E+1 kg/yr

to: water, incineration, or landfill (RM-2)

from: Spillage During Raw Material Handling

basis: User-Defined Loss Rate Model. TThe submission does

not address plastic converting operations. A 1992 RM-2

assessment for SCCPs estimated releases from spills to be

0.1% of the PV with 90% of releases going to incineration

landfill and 10% going to water. A 2010 EU CSR assessment

on MCCPs estimated these releases to be 0.01% of PV with

releases to water or solid waste. The 2010 EU CSR

estimate is derived from more recent data sources and is

therefore used as a basis to estimate releases from

spillage.

Water or Incineration or Landfill

Conservative: 2.2E+0 kg/site-day over 250 days/yr from 33

to: water or landfill (ESD)

from: Scrap Material

basis: User-Defined Loss Rate Model. The submission does

not address rubber converting operations. A 1992 RM-2

assessment for SCCPs estimated scrap from trimming to be

1% of the PV with 90% of releases going to landfill. The

2004 ESD for Plastics Converting estimated these releases

to be 2.5% of PV with releases to water or landfill. This

is based on the assumption that large pieces of scrap

material will be disposed to landfill via solid waste and

dust generated during trimming will settle to the floor

and be washed away to wastewater during cleaning. Due to

multiple unknown downstream sites, CEB conservatively

assesses a 2.5% loss rate with releases to water or

landfill based on the ESD.

Air

Suggested Estimate: 2.7E-1 kg/site-day over 250 days/yr

from 33 sites

to: water or air (ESD, 2010 EU CSR)

from: Fugitive Air Emission During Forming and Molding

ENVIRONMENTAL RELEASES ESTIMATE SUMMARY

IRER Note: The daily releases listed for any source below

may coincide with daily releases from the other sources

The submitter has stated that "Due to the large number

Page 29 of 46

estimates an aggregared loss of 1% from

misting/evaporation and dragout with releases to POTW.

The 2011 ESD for MWF Operations estimates a loss rate of

11% from dragout with releases to on-site WWTP or POTW.

These data are based on U.S. industry data collected

during the development of effluent guidelines for the

metalworking industry. These data provide the best

representation of U.S. operations and are more

conservative than the submitter estimates. Due to

uncertainty at multiple downstream sites, CEB assesses

dragout releases using the ESD estimate of 11% and

accounting for upstream losses from container cleaning:

(1-0.03) x 0.11 = 0.1067. Releases are assessed to water

via on-site WWTP or POTW per submission and ESD. // NOTE

FOR CEB DRAFT: A 2002 EU RA for MCCPs estimates workpiece

dragout to account for 1 to 2% with releases water or

chemical waste and grinding swarf dragout is estimated to

be 30 to 90% with relesaes to incineration or landfill. A

2010 EU CSR for MCCPs estimates overall process losses to

be 1 to 6% with releases to water. The data from the 2011

ESD is most representative of U.S. industry and is

therefore used as the basis for releases.

Water or Incineration or Landfill

sites

or 3.4E+4 kg/yr

to: water, incineration, or landfill (ESD)

from: Cleaning Liquid Residuals from Drums Used to

Transport the Raw Material

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

residual. The submission estimates 0.15 kg/site-day of

PMN (~3% based on use at 9,070 sites estimated by the

submission) released to landfill from container residuals.

The 2011 ESD for MWF Operations estimates releases using

the EPA/OPPT drum residual model (3% loss rate) with

releases to water, incineration, or landfill. Due to

uncertainty at multiple downstream sites, these releases

are assessed to uncertain media using a 3% loss rate.

Water or Incineration or Landfill

Output 2: 6.4E+0 kg/site-day over 247 days/yr from 250

or 4.0E+5 kg/yr

to: water, incineration, or landfill (ESD)

from: Filter Media and Other Recycling Waste

basis: User-Defined Loss Rate Model. The submission does

not address releases from recycling or filter media

losses. The 2011 ESD for MWF Operations estimates these

releases to account for a 36% loss rate with releases to

water, incineration, or landfill (water-based fluids) or

incineration or landfill (straight-oil). Accounting for

upstream container cleaning losses: (1-0.03) x 0.36 = 0.

Water or Incineration or Landfill

Output 2: 8.2E+0 kg/site-day over 247 days/yr from 250

sites

or 5.1E+5 kg/yr

to: water, incineration, or landfill (ESD)

from: Spent Metalworking Fluid

basis: User-Defined Loss Rate Model. The submission

assesses the remaining fluid to POTW from spent MWF

disposal with bath changouts occuring 5 times/yr. The

2011 ESD for MWF Operations also assesses 100% release

with the spent MWF disposed to water (water-based fluids)

or incineration or landfill (straight oil fluids) with at

least one bath changeout occuring per day at a facility

with multiple baths in use. Based on uncertainty at

multiple downstream use sites, CEB assesses the spent MWF

to water, incineration, or landfill. Account for upstream

losses, the loss rate is calculated as: (1-0.03) x (1-0.

05-0.11-0.38) = 0.4462.

Air

Output 2: 8.9E-1 kg/site-day over 247 days/yr from 250

sites

to: air (2002 EU RA)

from: Misting/Evaporation

basis: User-Defined Loss Rate Model. The submission

estimates an aggregate loss rate of 1% from

misting/evaporation and dragout. A 2002 EU RA for MCCP

estimates misting/evaporation losses to range from 2 to

5% depending on the type of MWF begin used. Based on

uncertainty at multiple downstream sites, CEB uses the

most conservative estimate of 5% loss to air from

misting/evaporation. Account for upstream losses from

container cleaning: (1-0.03) x 0.05 = 0.0485.

High End of Range: 3.6E+0 mg/day over 247 days/yr

Number of workers (all sites) with inhalation exposure: 12,

Basis: Exposure During Metalworking Operation;

User-defined Inhalation Model. The 2011 ESD for MWF

Operations estimates typical mist concentrations ranging
Page 31 of 46

from 0.19 to 0.39 mg/m3 and high end concentrations

ranging from 0.87 to 1.42 mg/m3 depending on the type of

MWF used. These estimates are based on the geometric mean

(typical) and 90th percentile data (high end) of data

collected by NIOSH from 942 machinists at 79 shops across

the U.S. A range of inhalation exposure estimates are

based the high end for the range of geometric means and

90th percentiles and a PMN concentration of 2.5% in the

mist. // NOTE FOR CEB DRAFT: A 2002 EU RA for MCCPs

estimates mist concentrations from 1.6 to 3.4 mg/m3 based

on the 95th percentile of data collected in the EU for

oil-based and water-based fluids. The data from the 2011

ESD are more representative of U.S. operations since the

data were collected in the U.S.

NOTE: The respirator class is: I. Particulate (including

solid or liquid droplets).

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. The releases estimates were based on

a combination of submitter and estimates from the 2000 GS

for Lube Oil Additives.The submitter has stated that "Due

to the large number of customers and potential sites

where the notification substances may be used, specific

use information for each site could not be obtained.

Rather, these worker exposures and environmental releases

scenarios are average scenarios for each particular use."

Due to the uncertainty at multiple downstream use sites,

the most conservative data were chosen when evaluating

releases for downstream operations.

Water

basis: User-Defined Loss Rate Model. The 2001 GS for Lube

Oil Additives estimates 0.7 kg/site-day of PMN released

based on 1% concentration in lube oil. For 4%, the

equivalent release would be 2.8 kg/site-day. Due to

uncertainty at multiple downstream processing sites, CEB

includes this release in the assessment.

to the same medium. The releases estimates were based on

a combination of submitter provided data and data

available in various literature sources. A description of

the data is provided in the release notes for each source.

The submitter has stated that "Due to the large number

of customers and potential sites where the notification

substances may be used, specific use information for each

estimates 7.1 kg/site-day of PMN (7.1/286 = 2.5%)

released to incineration from equipment cleaning. The

2010 ESD for the Formulation of Radiation Curable

Coatings, Inks, and Adhesives uses the EPA/OPPT Single

Vessel Residual model and assesses releases to

incineration, or landfill. The 2011 GS for the

and a 2010 EU CSR on MCCPs presents air monitoring data

from paint spray application with values ranging from 0.

002 to 0.19 mg/m3 with a median of 0.04 mg/m3 and a 90th

percentile of 0.085 mg/m3. The EPA/OPPT Autorefinishing

Spray Coating Model calculates an exposure of 9 mg/m3.

The EPA/OPPT model is used to provide a conservative

estimate due to uncertainy in downstream use sites.

NOTE: The respirator class is: I. Particulate (including

solid or liquid droplets).

INITIAL REVIEW ENGINEERING REPORT 

PMN: 12-0283

USE6: Plasticizer/Flame Retardant in Textiles (0.5% of PV)

Number of Sites/ Location: 11

multiple sites - See Attachment 008 for a full list of

customers across all downstream operations

Days/yr: 95

Basis: Per submssion, 11 finishing sites, 95 days/yr, PMN

used at 91.5 - 100% and formulated to 5% in finishing

bath. CEB assumes 100% in raw material. CS calculates a

use rate of 18.0827 kg/site-day.

Process Description: PMN (liquid, 91.5 - 100%) is

unloaded from tanks trucks (69% of PV), drums (23% of PV),

totes (4% of PV), and railcars (4% of PV) ---> feed

into finishing solution tank with other components (PMN,

liquid, 5%) ---> fabric is moved through the bath ---> 

transfer heated rollers ---> PMN entrained in coating on

fabric (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. The releases estimates were based on

submitter due to lack of information from other sources.

The 1994 GS for Fabric Finishing was referenced for

comparison. The submitter has stated that "Due to the

large number of customers and potential sites where the

notification substances may be used, specific use

information for each site could not be obtained. Rather,

these worker exposures and environmental releases

scenarios are average scenarios for each particular use."

Due to the uncertainty at multiple downstream use sites,

the most conservative estimate was chosen when evaluating

releases for downstream operations.

Water

Output 2: 3.6E+0 kg/site-day over 95 days/yr from 11 sites

to: POTW (submission, GS)

from: Dumping of Finishing Bath

basis: User-Defined Loss Rate Model. The submission

estimates 3.6 kg/site-day of PMN (3.6/18.1 = 20%)

released to POTW from dumping the finishing bath. The

1994 GS for Fabric Finishing estimates a fabric pick up

between 60 and 100% with bath dumping to water. The

submission estimates are in general agreement with GS

estimates.

Water or Incineration or Landfill

High End: 6.2E+0 kg/site-day over 2 days/yr from 11 sites

or 1.4E+2 kg/yr

to: uncertain
Page 45 of 46

from: Cleaning Liquid Residuals from Drums Used to

Transport the Raw Material

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

residual. The submission estimates 0.54 kg/site-day of

PMN (0.54/18.1 = 3%) released to landfill from drum

residuals. This is in agreement with the EPA/OPPT Drum

Residual Model. As conservative, CEB assesses these

releases to uncertain media due to uncertainty in

downstream operations.

Water or Incineration or Landfill

Submitter Estimate: 4.6E+0 kg/site-day over 1 day/yr from

11 sites

or 5.0E+1 kg/yr

to: uncertain

from: Cleaning Liquid Residuals from Totes, Tank Trucks,

and Rail Cars Used to Transport the Raw Material

basis: User-Defined Loss Rate Model. The submission

estimates 0.04 kg/site-day of PMN (0.04/18.1 = 0.22%)

released to landfill from bulk container residuals. This

estimate is slightly more conservative that the EPA/OPPT

Bulk Transport Residual Model. As conservative, CEB

assesses these releases to uncertain media using the

submission estimate due to uncertainty in downstream

operations.

RELEASE TOTAL

4.0E+3 kg/yr - all sites

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 33

Basis: the submission estimates 2 workers/site. CEB

assesses the default minimum of 3 workers/site.

Concerning what TSCA ?

PMN: 12-0283

Q1: Process information and releases and exposure

information are provided for plastic and rubber

compounding. However, information for plastics and rubber

converting into final articles is not addressed. Do you

have similar information available for downstream plastic

and rubber converting operations?| A1: We do not have

sufficient information for any downstream converting

opreations. We have discussed this particular issue

during the preparation of the PMN submissions. We felt

that we did not have enought information on this process

to feel comfortable adding the information to the

submission. | | Q2: Can you provide some detail as to how

release estimates were calculated for downstream use? |

A2: We used EPA models to calculate most of the releases.

We also asked for voluntary information from some of our 

customers such as use concentration, number of workers,

and number of downstream customers.
