Compounds with reactivity levels lower than, or equal to, ethane under the assumed conditions, may be deemed negligibly reactive. For the purpose of this rule, tertiary butyl acetate (tBAc) shall be considered exempt as a VOC only for purposes of VOC emissions limitations or VOC content requirements and will continue to be a VOC for purposes of all recordkeeping, emissions reporting, photochemical dispersion modeling, and inventory requirements which apply to VOCs, when used in industrial maintenance coatings, including zinc-rich industrial maintenance coatings and non-sacrificial anti-graffiti coatings.". WebWhy Regulate VOCs in Coatings? Although not VOC-exempt in Europe, acetone has low ozone-forming potential and should have minimal impact on tropospheric ozone compared to other, more reactive solvents. hbbd```b``z"gI;Zf`}`c0"@dMY$s_&Fg`` + By clicking Accept All, you consent to the use of ALL the cookies.

WebCARB defines "VOC exempt" compounds as those not expected to meaningfully contribute to ozone formation due to their low reactivity in the atmosphere. The one exception is that wipes contaminated with trichloroethylene are only eligible for the reusable wipes exclusion at 40 CFR section 261.4(a)(26). 215 0 obj <>stream WebHowever, some VOC-like compounds have negligible smog-forming effects and are known as exempt VOCs. Except for the chem icals listed in 40 CFR 51.100 (s), all organic chemi cals, regardless of their vapor pressure, are regu lated as VOCs. Thus, the ground level is less polluted, creating cleaner breathing air that promotes lung health in not only humans but animals as well. The potential for a VOC to react with NOx to form smog, i.e., the maximum incremental reactivity (MIR) of a VOC, varies from compound to compound.

Unfortunately, the majority of the compounds that are on the exempt li~t cannot be used as indus trial solvents for metal finishing. Acetone was exempted by final rule published June 16, 1995 (60 FR 31633). VOC exempt solvents are used in applications where traditional solvents are used. In the US, dimethyl carbonate was exempted under the definition of volatile organic compounds (VOCs) by the U.S. EPA in 2009. Volatile Organic Compounds are compounds that combine with nitrogen oxides found in the air, to form harmful smog (ozone) when they come in contact with sunlight. 0 Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet.
