    Start Preamble AGENCY: Environmental Protection Agency. ACTION: Final rule. SUMMARY: This action lists two substitutes for ozone-depleting substances (ODSs) in the fire suppression and explosion protection sector as acceptable (subject to use restrictions) under the U.S. Environmental Protection Agency's (EPA) Significant New Alternatives Policy (SNAP) program.   Ozone depleting substances (ODS) as listed by the Montreal Protocol (UNEP‐OS, ). Pesticide AI and formulations that have shown a high incidence of severe or irreversible adverse effects on human health or the environment. The human health hazards were deemed to be unacceptable if an AI met any of the HHP criteria (FAO,

    Ozone-depleting substances Freon gas is a global warming substance other than CO 2. The use of chlorofluorocarbons and hydrochlorofluorocarbons (HCFCs) as refrigerants for air conditioners in trains and buildings is currently regulated by the Law Concerning the Protection of the Ozone Layer through the Control of Specified Substances and Other. Terms and purposes. The treaty is structured around several groups of halogenated hydrocarbons that deplete stratospheric ozone. All of the ozone depleting substances controlled by the Montreal Protocol contain either chlorine or bromine (substances containing only fluorine do not harm the ozone layer). Some ozone-depleting substances (ODSs) are not yet controlled by .

EPA allows the import of used ODS to ease the transition to ODS alternatives. EPA has a petition process to verify that the ODS were actually used. Petition requirements are available in 40 CFR (g)(2) and 40 CFR (c)(2), (3), and (4).

EPA must receive the petition 40 working days before the shipment is to leave the foreign port of export. See ozone depleting substance. (HCFCs). For each ODS, this page provides the compound’s atmospheric lifetime, Ozone Depletion Potential ozone depletion potentialA number that refers to the amount of ozone depletion caused by a substance.

The ODP is the ratio of the impact on ozone of a chemical compared to the impact of a similar mass of CFC Register to use ozone-depleting substances for laboratory or analytical purposes Applying for a licence to import or export ozone-depleting substances Record and report ozone-depleting substances Author: Environment Agency.

The main cause of ozone depletion and the ozone hole is manufactured chemicals, especially manufactured halocarbon refrigerants, solvents, propellants, and foam- blowing agents (chlorofluorocarbons (CFCs), HCFCs, halons), referred to as ozone-depleting substances (ODS).These compounds are transported into the stratosphere by turbulent mixing after being.

the chemical has a greater ability than CFC to destroy the ozone layer; an ODP lower than means that the chemical’s ability to destroy the ozone layer is less than that of CFC In Septemberthe Montreal Protocol on Substances That Deplete the Ozone Layer (the Protocol) was signed by 25 nations and the Eu-ropean Community.

Agency (EEA) report, Ozone-depleting substances, provides an updated aggregated overview of key data on ozone-depleting substances in the European Union.

The report also presents the major trends observed since The report is based on the data on import, export, production, destruction, and feedstock and process agent use of ODS, reported by.

The Ozone Protection and Synthetic Greenhouse Gas Management Act controls the manufacture, import export, use and disposal of ozone depleting substances in Australia. Bulk import into Australia of most of these substances (except HCFCs and methyl bromide) is banned.

The Montreal Protocol, ratified inwas the first of several comprehensive international agreements enacted to halt the production and use of ozone-depleting chemicals. As a result of continued international cooperation on this issue, the ozone layer is.

Ozone Depleting Substances (ODS) “Ozone depleting substances are the substances such as chlorofluorocarbons, halons, carbon tetrachloride, hydrofluorocarbons, etc. that are responsible for the depletion of ozone layer.” Following is the list of some main ozone-depleting substances and the sources from where they are released.

The Montreal Protocol on Substances that Deplete the Ozone Layer is a global agreement to protect the Earth’s ozone layer by phasing out the chemicals that deplete it. This phase-out plan includes both the production and consumption of ozone-depleting substances.

The landmark agreement was signed in and entered into force in   use of ozone-depleting substances for chemical feedstock. 61 how the ods 6 process agents appendix 2: alternatives for use of carbon tetrachloride (ctc) as a solvent for bromination reactions involving n-bromosuccinimide (nbs) agents in polyurethane (PU) foams, cleaning solvents and are appropriate for the chemical(s).

Safer Alternatives There are many alternative products and production processes that do not use ozone depleting substances and may be suitable for your production needs.

Any chosen alternative must be ZDHC MRSL compliant whenever applicable. Ozone-depleting substances Aggregated data reported by companies on the import, export, production, destruction, and feedstock and process agent use of ozone-depleting substances in the European Union EEA Report No 19/ Ozone Depleting Potential.

It refers to the amount of ozone depletion caused by a substance. More specifically, it is the ratio of global loss of ozone due to a given substance and global loss of ozone due to trichlorofluoromethane (CFC) of the same mass.

CFC is assigned an ODP value of 1. The OPD values of. Ozone-depleting substances (ODS) contain various combinations of the chemical elements chlorine, fluorine, bromine, carbon, and hydrogen and are often described by the general term halocarbons.

These substances are effective ozone-depleters for two reasons. The first is that they are not reactive (chemically speaking), which means they survive long enough in the. Products that normally contain ozone depleting substances should be replaced with functionally similar products that contain non-ozone depleting substances.

Requirements and Policy Statutory Requirements. The Environmental Protection Agency (EPA) established standards regarding the use and disposal of ODS under the authority of Section (a. (7) Notes: Ozone Depleting Substances. (a) Ozone depleting substances (ODS) are agents such as, but not limited to 1,1,1 trichloroethane (aka methyl chloroform) and trichlorotrifluoroethane (aka Freon or CFC or R).

These agents are still used in some aircraft maintenance processes. Alternative. Global measurements and projected future abundances of the chlorine- and bromine-bearing gases believed responsible for most of the ozone depletion (referred to as ozone-depleting substances (ODSs)) are shown in Figure 4.

These data indicate that the combined equivalent effective stratospheric chlorine (EESC) abundance (EESC is a measure of the. The Montreal Protocol on Substances that Deplete the Ozone Layer (“Montreal Protocol”) restricts the use of Ozone-depleting substances (ODSs) in manufacturing and Sections and of the US Internal Revenue Code (IRC) impose an excise tax on the sale or use of ODSs by the manufacturer, producer or importer of the ODS and the sale or.

Ozone depleting potential is a measure of how much damage a chemical can cause to the ozone layer compared with a similar mass of trichlorofluoromethane (CFC). CFC, with an ozone depleting potential ofis used as the base figure for measuring ozone depleting.

In56 countries agreed under what became known as the Montreal Protocol to cut CFC production and use in half. In subsequent years, the protocol was strengthened to require an eventual worldwide phaseout of the production of CFCs and other ozone depleting chemicals.Hazardous aspects of ozone depleting substances are controlled by the Hazardous Substances and New Organisms Act [New Zealand Legislation website].

Reducing ozone depleting substances New Zealand is a signatory to the Montreal Protocol on Substances that Deplete the Ozone Layer which sets targets for reducing the production and consumption.Worldwide action to phase out ozone-depleting substances has resulted in remarkable success, according to a new assessment by international scientists.

The stratospheric ozone layer, a fragile shield of gas that protects Earth from harmful ultraviolet light, is on track to recovery over the next few decades.
