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.

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.

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.

14 CFR Part 71

[Docket No. FAA-2010-0183; Airspace Docket No. 10-ASW-5]

Amendment of Class D Airspace; Fort Worth NAS JRB (Carswell
Field), TX

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This action amends the geographic coordinates within the Fort
Worth Naval Air Station (NAS) JRB (Carswell Field), TX, area and
renames the navigation aids, at the request of the U.S. Navy, that are
listed in the description. This action does not change the boundaries
or operating requirements of the airspace.

DATES: Effective date: 0901 UTC, March 10, 2011. The Director of the
Federal Register approves this incorporation by reference action under
1 CFR part 51, subject to the annual revision of FAA Order 7400.9 and
publication of conforming amendments.

FOR FURTHER INFORMATION CONTACT: Scott Enander, Central Service Center,
Operations Support Group, Federal Aviation Administration, Southwest
Region, 2601 Meacham Blvd., Fort Worth, TX 76137; telephone (817) 321-
7716.

SUPPLEMENTARY INFORMATION:

The Rule

    This action amends Title 14 Code of Federal Regulations (14 CFR)
part 71 by adjusting the geographic coordinates of the Fort Worth NAS
JRB (Carswell Field) Class D airspace, Fort Worth, TX, and the
navigation aids, to coincide with the FAAs Aeronautical Products. This
action also changes the names of the Carswell ILS Localizer North,
Carswell ILS Localizer South, and Carswell TACAN to the NAS JRB Fort
Worth ILS Localizer North, NAS JRB Fort Worth ILS Localizer South, and
NAS JRB Fort Worth TACAN at the request of the U.S. Navy. This is an
administrative change and does not affect the boundaries, altitudes, or
operating requirements of the airspace, therefore, notice and public
procedures under 5 U.S.C. 553(b) are unnecessary.
    The FAA has determined that this regulation only involves an
established body of technical regulations for which frequent and
routine amendments are necessary to keep them operationally current.
Therefore, this regulation: (1) Is not a ``significant regulatory
action'' under Executive Order 12866; (2) is not a ``significant rule''
under DOT Regulatory Policies and Procedures (44 FR 11034; February 26,
1979); and (3) does not warrant preparation of a regulatory evaluation
as the anticipated impact is so minimal. Since this is a routine matter
that will only affect air traffic procedures and air navigation, it is
certified that this rule, when promulgated, will not have a significant
economic impact on a substantial number of small entities under the
criteria of the Regulatory Flexibility Act.
    The FAA's authority to issue rules regarding aviation safety is
found in Title 49 of the U.S. Code. Subtitle 1, section 106, describes
the authority of the FAA Administrator. Subtitle VII, Aviation
Programs, describes in more detail the scope of the agency's authority.
This rulemaking is promulgated under the authority described in
subtitle VII, part A, subpart I, section 40103. Under that section, the
FAA is charged with prescribing regulations to assign the use of
airspace necessary to ensure the safety of aircraft and the efficient
use of airspace. This regulation is within the scope of that authority
as it amends controlled airspace at Fort Worth NAS JRB (Carswell
Field), Fort Worth, TX.

List of Subjects in 14 CFR Part 71

    Airspace, Incorporation by reference, Navigation (Air).

Adoption of the Amendment

    In consideration of the foregoing, the Federal Aviation
Administration amends 14 CFR part 71 as follows:
