INTRODUCTION

GENERAL INSTRUCTIONS

This form may be used to submit information under the Significant New
Alternatives Policy (SNAP) program for the review of alternatives to
class I and class II ozone-depleting substances (ODS) under section 612
of the Clean Air Act.  Submitters are required to provide this
information on new substitutes to assist the Agency in assessing the
acceptability of chemicals or processes that are considered alternatives
for ODSs.  A separate notice must be filed for each alternative you are
submitting.

All submissions must be provided in three complete copies.  If
information is to be claimed as confidential, all confidential
information must be excised from one of the copies, which will be placed
in the public docket; the other two copies must include the confidential
material.  If no claims of confidentiality are made for the submission,
all copies must be identical.

The attached “Guidance Manual for the SNAP Information Notice” is
designed to assist applicants in completing this form.  The manual
provides instructions on submitting a SNAP notice, asserting
confidentiality claims, completing the notice form, sector-specific data
requirements, and submitting test data and supplemental information.

To facilitate Agency review of alternatives, this form must be filled
out as completely as possible.  Please provide all information requested
to the extent that it is known or reasonably ascertainable.  Make
reasonable estimates if actual data is unavailable.

2.  Describe whether and how the alternative is regulated under health
and safety related statutory authorities, such as those implemented by
the Food and Drug Administration (FDA), the Occupational Safety and
Health Administration (OSHA), the Department of Transportation (DOT),
and state and local laws.  List any concentration-based or other
numerical standards to which the alternative is subject under the above
statutes and regulations.  Also list any other standard-setting
organizations such as the National Fire Prevention Association (NFPA) or
the American Society of Heating, Refrigerating, and Air Conditioning
Engineers (ASHRAE), by which the substitute is evaluated.

FDA: GRAS (Generally Recognized As Safe)

OSHA: TLV-TWA value of 5,000 ppm

DOT:   Vapor UN1013, Liquid UN2187, Class 2.2, 

ASHRAE: Considered as A1 refrigerant (R-744) which is non-flammable (no
flame propagation), low-toxicity as stated in ASHRAE Standard 34. 
System design for CO2 refrigeration equipment (and all refrigeration
equipment) is covered by ASHRAE Standard 15 – this standard is
currently being revised to add language specific to use of CO2 as a
refrigerant and secondary coolant. 

Additional notes: ASHRAE has released a “Position Document on Natural
Refrigerants” which was approved by their board on Jan. 28, 2009. 
Regarding CO2, their viewpoint is that “carbon dioxide has found
widespread acceptance in the full range of vapor compression systems,
from low-temperature freezers to high-temperature heat pumps. It has
also been widely used as a secondary refrigerant, offering significant
improvements in efficiency compared with traditional water, glycol or
brine systems.”  This document is provided as an attachment to this
application.  ASHRAE is also adding a chapter specifically on CO2
Refrigeration Systems to the upcoming 2010 Refrigeration Handbook.

a. Substitute is currently widely available

b. N/A – application for refrigeration uses only small % of total
production 

c. Estimated 10 years to maximum market penetration

d. Implementation of substitute not expected to impact annual production
amounts

e. Estimated market penetration of 80% of low-temperature refrigeration
systems

3.  Describe any new equipment and use profiles.  If retrofitting of
existing equipment is required, detail changes in technologies needed to
use the alternative and address any materials compatibility issues. 
Provide information on each end-use and capital costs associated with

Section E - OCCUPATIONAL EXPOSURE AT END-USE

For all end-use scenarios of the substitute (end-uses utilizing the
substitute in products and/or processes):

     (a) Describe the activities in which workers may be exposed to
chemicals.

     (b) Describe any protective equipment or engineering controls used
to protect workers (e.g. goggles, gloves, chemical hoods).

     (c) Indicate the physical form of chemicals at the time of
handling/exposure (e.g. solid, liquid, gas).

     (d) Estimate average and maximum numbers of workers involved in
each activity.

     (e) Estimate average and maximum duration of activity for any
worker, in terms of (1) hours/day and (2) days/year.

     (f) Enter the contact pathway (e.g. ingestion, inhalation, dermal).

     (g) Estimate the average and high-end exposure concentrations
(separated by a /), being sure to provide units.

Start-up, service, and maintenance of refrigeration equipment containing
the substance

Gloves, safety glasses – consistent with industry practice

Liquid and gas most typical

Average 1, maximum 3

Average 4 hours/day, 8 days/year.  Maximum 10 hours/day, 30 days/year

Primarily inhalation

Average 375 ppm (background concentration in air).  High-End 4,000 ppm
during leak inspection and servicing system.  High-End exposure most
likely encountered in mechanical room.  Leak detection (per ASHRAE-15)
set at 3,000-5,000 ppm would initiate exhaust system to bring fresh
outdoor air into mechanical room and exhaust CO2 outside.

Training of personnel installing, servicing, starting-up, using, and
maintaining systems using CO2 as the working fluid has shown to be very
important to successful implementation.  Hill PHOENIX has developed
training classes for all new technologies as part of the “Hill PHOENIX
Learning Center” – this includes manuals and presentation materials
that go along with classroom instruction.  Please see attached document
“SNLTX2 Installation Guide – Draft Feb 2008” that was developed
prior to the first test system installed in the field – it is a result
of knowledge gained from our experiences in testing the cascade
technology in the laboratory, along with extensive experience using CO2
as a secondary coolant.  This document (to be considered CONFIDENTIAL)
will be enhanced over time as more experience is gained through
additional field installation. 

Section F - CONSUMER EXPOSURE

For each end-use of a substitute:

     (a) Identify the potentially exposed population (e.g. indoor
residents).

     (b) Identify the exposure medium (e.g. air).

     (c) Enter the contact pathway (e.g. ingestion, inhalation, dermal).

     (d) Enter the exposure point of concentration.  Provide (1) average
and (2) high-end estimates.

Shoppers in supermarket containing displays refrigerated with the
substitute. 

Exposure via air

Inhalation

Average 375 ppm (background concentration in air).  High-End (estimate):
1000 ppm during 25% leak event (single large circuit).  Catastrophic
leak event (100% of charge, extremely unlikely): 4000 ppm

Item “d” calculation example: Typical 35,000 sqft supermarket with
18’ ceilings – internal volume = 630,000 ft3

Total CO2 charge for LT cascade refrigeration system approx. 275 lbs.

Vapor volume at 75ºF, 1 atm. = 0.1133 lb/ft3

Partial leak event: 25% charge = 69 lbs CO2 = 609 ft3 CO2  >>
Concentration = 0.000966 or 966 ppm

Catastrophic leak event: 275 lbs CO2 = 2427 ft3 CO2 >> Concentration =
0.00385 or 3850 ppm

Note: Catastrophic leak events are generally on discharge side of system
in mechanical room, not sales area.
