## 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 - dep leting 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 y ou 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, wh ich 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, secto r specific data requirements, and submitting test data and supplem ental information. To facilitate Agency

review of alternatives, this form must be filled out as completely as possible. Please provide all info rmation requested to the extent that it is known or reasonably ascertainable. Make reasonable estimates if act ual data is unavailable.

Sub stantiation of this claim must also be provided at this time. All information claimed as CBI will be treated in a manner consistent with 40 CFR Part 2, Subpart B. Failure to assert a claim of confidentiality at the time of submission may

result in disclo sure of information by the Agency

without further notice. To assert a claim on this form, circle or bracket the information y ou claim as confidential and mark the confidential box at the bottom of the page. Then provide substantiation of this claim on an attachment to the notice. If any information is claimed as confidential, y ou must provide a “sanitized” version of this notice, including attachments, to EPA with our submission. For additional information on claiming information as confidential, please see the Instructions Manual. Information submitted as CBI may be accessed by

companies designated as Authorized Representatives of the United States Environmental Protection Agency (EPA) under an EPA contract for the purpose of assisting EPA in the devel opment and implementation of national regulations for the protection of stratospheric ozone, including the development of the SNAP progr am. These Authorized Representatives may have access to any

information received by the Stratospheric Protection Divisi on within EPA Office of the Atmospheric Programs for use in reviewing the need for possible control of any substance, practice, process or activity that may reasonably be anticipated to affect stratospheric ozone. Access to such information is necessary t o ensure that these companies can complete the work required by the contract.

**TIONA L EX**  **POSURE A T 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 contr ols used to protect workers (e.g. goggles, gloves, chemical hoods). (c) Indicate the phy sical 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 aver age and maximum duration of activity for any worker, in terms of (1) hours/day and (2) day s/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 pro vide units. (a) RS - 5 0 IS A REFRIGERANT TO REPLACE R22, R404 AND R507 AND W ILL BE HANDLED AND USED IN THE SAME MANNER AS OTHER REFRIGERANTS. GOOD HOUSEKEEPING, SAFE PRACTICES AND OBSERVATION OF REGULATIONS ON VENTING TO ATMOSPHERE W ILL AVOID END - USERS BEING EX POSED TO RS - 5 0 AND ITS CONSTITUENTS. (b) INFORMATION ON PERSONAL PROTECTIVE EQUIPMENT HANDLING AND THE RECOMMENDED EXPOSURE LEVEL (TW A) OF 1000 PPM IS GIVEN IN THE PRODUCT SAFETY DATA SHEET. HOW EVER, LOCAL CONCENTRATIONS DURING CHARGING AND SERVICING OF EQUIP MENT W ILL BE CONSIDERABLY BELOW THE TW A. (c) RS - 5 0 IS HANDLED AS A LIQUEFIED GAS UNDER PRESSURE. (d) SITE SERVICE W ORK INVOLVING RS - 5 0 IS NORMALLY UNDERTAKEN BY

INDIVIDUAL REFRIGERATION AND AIR CONDITIONING ENGINEERS. (e) THE DURATION FOR HANDLING RS - 5 0 BY W ORKERS INVOLVED IN EQUIPMENT MANUFACTURE OR SERVICE WO RK IS LIMITED TO THE RELATIVELY SHORT TIME OF CHARGING THE NEW REFRIGERANT. (f) THE CONTACT PATHW AY W OULD BE INHALATION SHOULD ANY RELEASE OCCUR. (g) UNDER NORMAL CONDITIONS OF END - USE, THE EXPECTED EXPOSURE CONCENT RATION IS NEGLIGIBLE.Form 1265 - 93 (Revised 1/05)

## 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) Ente r the contact pathway (e.g. ingestion, inhalation, dermal). (d) Enter the exposure point of concentration. Provide (1) average and (2) high - end estimates. (a) RS - 5 0 IS A REPLACEMENT REFRIGERANT FOR USE IN LEAK - FREE REFRIGERATION AND AIR CONDITIONING SYS TEMS. HENCE, EXPOSURE TO THE GENERAL CONSUMER IS EXTREMELY REMOTE. SHOULD EMISSIONS OCCUR, THEY

W OULD MOST LIKELY BE THE RESULT OF EQUIPMENT LEAKAGE, PARTICULARLY AT THE HIGH PRESSURE SIDE OF THE EQUIPMENT. AS LEAKS TEND TO DEVELOP GRADUALLY AND THE HIGH P RESSURE SIDE OF LARGER EQUIPMENT IS USUALLY REMOTE FROM GENERAL CONSUMERS AND THE PUBLIC AND LOCATED IN W ELL VENTILATED AREAS, THE LIKELY POPULATION TO BE EXPOSED IS EXTREMELY SMALL. (b) THE EXPOSURE MEDIUM W OULD BE AIR. (c) THE CONTACT PATHW AY W OULD BE INHALATI ON SHOULD EXPOSURE OCCUR. (d) THE CONCENTRATION AT THE EXPOSURE POINT IS EXPECTED TO BE EXTREMELY LOW AND VERY INFREQUENT, IF AT ALL.

## Part III **- RELEA** **SE A ND EXPOSURE DA**  **TA (continued)**  **Section G -**  **GENERA L POPULA**  **TION EXPOSURE (optional)** For manufacturing of substitutes and products containing substitutes: (a) Identify

and number potential expos ure points. (b) For each exposure point described in (a), identify the potentially

exposed population (e.g. residents at the fenceline). (c) Identify

the contact pathway (e.g. ingestion, inhalation, dermal). (d) Identify

the exposure medium (e.g. air, water). (e) Enter the exposure point concentration (mg/m 3 ). Provide (1) average and (2) high - end estimates. THE GUIDANCE DOCUMENT STATES: “ YOU DO NOT NEED TO PROVIDE THE INFORMATION REQUESTED IN THIS SECTION UNLESS Y OU CHOOSE TO DO SO.” (a)&(b) IT IS NOT ANTICIPATED THAT THE GENERAL PUBLIC W OULD COME INTO DIRECT CONTACT W ITH PARTS CONTAINING RS - 5 0 . EMISSIONS FROM EQUIPMENT LEAKAGE, OR EVEN FAILURE, W OULD BE CONFINED TO THE RELATIVELY

SMALL AREA AROUND THE EQUIPMENT. HENCE, EXPOSURE TO TH E GENERAL PUBLIC W OULD BE EXPECTED TO BE NEGLIGIBLE AND VIRTUALLY ZERO. (a) THE CONTACT PATHW AY W OULD BE INHALATION SHOULD EXPOSURE OCCUR. (b) THE EXPOSURE MEDIUM W OULD BE AIR. (c) THE CONCENTRATION AT THE EXPOSURE POINT IS EXPECTED TO BE VIRTUALLY ZERO.
