PV (kg/yr): 15,000 Import Only

Revision Notes / Assessment Overview: Revision 1/21/10: An

amendment was sent on 01/05/2010 indicating: (1) the NPDES

number for the WWTP in Wayne, NJ is 0028002 (Mountain View WWTP);

 (2) the PMN is imported as liquid only; and (3) dedicated

SUBMITTER: Green Era Solutions

USE: Fragrance ingredient. 

OTHER USES:

MSDS: Yes Label: No

Gen Eqpt: impermeable gloves to prevent prolonged skin contact /

use safety eye wear designed to protect eyes against liquid

splash and mists. / use protective clothing to prevent skin

contact; use head caps, boots, and chemical aprons when

necessary. / provide general or mechanical ventilation or local

exhaust to keep vapor concentrations low.

Respirator: a jointly approved NIOSH/MSHA air supplied

respirator is advised in absence of proper environmental control.

 OSHA regulations also permit other NIOSH/MSHA respirators under

specified conditions.

Health Effects: Inhalation: may caues headache or nausea / Eye:

may caue moderate eye irritation / Skin: prolonged or repeated

and confined exposure may cause skin irritation. repeated

contact may cause drying or flaking of skin. a single prolonged

exposure is not likely to result in the material being absorbed

through the skin in a harmful amount. the dermal LD50 has not

been determined. / Ingestion: swallowing can cause

gastrointestinal irritation, nausea, and diarrhea. / This

product is not considered to be a carcinogen but no studies have

been done at this time. / Some people may have an allergic

reaction to cypress oil.

NOTES & KEY ASSUMPTIONS:

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

1/21/10: An amendment was sent on 01/05/2010 indicating: (1) the

NPDES number for the WWTP in Wayne, NJ is 0028002 (Mountain View

WWTP); (2) the PMN is imported as liquid only; and (3) dedicated

transport containers will be returned to Canada and not cleaned

in the US. The IRER was updated accordingly. // The PMN is

imported; therefore no releases or exposures from manufacturing

were assessed. The PMN is a volatile liquid; therefore,

fugitive releases are calculated for each activity. Contact was

called, see contact report. /// 

 The current PMN is being imported to Mane USA. 

 This IRER assumes 100% consumer use as it is not addressed in

the submission

. /// 

 

 /// The Aug 2007

"Blending of Fragrance Oils into Commercial and Consumer

Products" GS was referenced for USE. The production volume of

consumer products in this case (15,000 kg/yr / 0.01 = 1,500,000

kg/yr or 3.3 million lb/yr) is less than the PV for continuous

processes given in the G.S. (4 to 25 million lb/yr); therfore,

CEB assumes that the "formulation into consumer products"

operation is batch-wise, not continuous 

POLLUTION PREVENTION CONSIDERATIONS:

None.

OCCUPATIONAL EXPOSURES ESTIMATE SUMMARY

Tot. # of workers exposed via assessed routes: 29

Basis: Technical contact stated that consumer products may be

solid or liquid (for example scented candle or lotion).

Therefore, solid exposures (inhalation and dermal were assessed).

 Submission states PMN in final product <1%. The Generic

Scenario for Fragrances states the typical % in formation can

range from 0.5% to 15% of fragrance oil (PMN concentration in

the oil can vary). Used 1% PMN in the consumer products as a

conservative estimate. Submission estimates 2 workers at one

site. GS estimates up to 29 workers per site.

Q1: Submission indicates PMN is imported to Mane USA site for

processing. Does Mane USA process fragrant into fragrance oil

AND formulate fragrance oil into final consumer product?| A1:

Yes, believe so. Will confirm.| | Q2: What is the

concentration and physical form of PMN as imported, in fragrance

oil, and in consumer product?| A2: PMN may be imported as neat

substance in liquid form or powder form. Fragrance oil

composition is unknown, but likely less than 5% PMN. Consumer

products can be anything, such as lotions or candles. PMN is

likely less than 1% in final consumer product, but is uncertain

Multiple release activities are combined in one exposure 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.

Note: The general Agency guidance for assessing short-term, infrequent events (for most chemicals, an exposure of less than 24 

hours that occurs no more frequently than monthly) is to treat such events as independent, acute exposures rather than 

as chronic exposure. (Methods for Exposure-Response Analysis for Acute Inhalation Exposure to Chemicals (External 

Review Draft). EPA/600/R-98/051. April 1998)

LEGEND FOR NEW CHEMICALS EXPOSURE REPORT 

This new chemicals exposure report was prepared by the Exposure Assessment Branch (EAB) of the Economics, 

Exposure and Technology Division, Office of Pollution Prevention and Toxics, USEPA. 

The goals of these reports are to calculate conservative (protective) estimates of exposure endpoints for consumers, 

the general population, and the environment. 

For each exposure scenario to industrial releases, the following three endpoints are calculated: 

(1) maximum possible acute concentrations and doses 

(2) maximum possible chronic concentrations and doses 

(3) for water releases ≥ 20 days, the probability of exceedence of the aquatic concentration of concern 

These endpoints are identified by abbreviations on the Release Activity line, e.g., (1) max ADR, (2) max 

LADD, (3) max PDM. Depending on the release inputs, these endpoints may be calculated and presented on 

the same page or different pages. That is, a release activity ID of mfg; max ADR, max PDM, max LADD

indicates that all the exposure endpoints were calculated from common manufacturing release values; 

conversely, a release activity ID of mfg &proc; max ADR indicates that only the maximum acute exposure 

values were calculated for manufacturing and processing releases that occurred at the same site. 

For each consumer product use exposure scenario, whether exposure is to the user directly or to the general 

population/environment, the maximum exposure values are calculated and presented together. 

In addition to the exposure values above, EPA policy directs that exposure and release values be compared to 

criteria threshold values for Exposure-based and PBT Exposure-based cases. 

Exposure-based (YX) cases (those with ≥ 100,000 kg/yr production volume) 

Criteria are exceeded under the following conditions: 

 Presence in consumer product with likely exposure 

≥ 3E-3 mg/kg/d exposure via air, fish ingestion or drinking water 

≥ 10,000 kg/yr release to environment (post-treatment) 

≥ 1,000 kg/yr release to water (post-treatment) 

Persistent, Bioaccumulative, Toxic (PBT) chemicals of P2B2 rating or higher and production volume ≥ 20,000 kg/yr 

Criteria are exceeded as for YX cases, with the following differences: 

≥ 2,000 kg/yr release to environment (post-treatment) 

≥ 200 kg/yr release to water (post-treatment) 

Bolding rules in the Report: Values for endpoints above that are also health or eco concerns are bolded.
