pending), developed by TBF Environmental Technology, is the first solvent not based on water or biomass to be Certified as a Clean Air Solvent by SCAQMD in over 20 years. South Coast AQMD reserves the right to decline to publish a link and will only publish workable links directly to the company listed. “Ultra Low VOC” is a classification unique to SCAQMD for solvents containing less than 25 g/L of VOC. The LEED´s definition of VOC should not be exclude the exempt compounds from the VOC content. VOC-exempt TBAC provides formulators with a practical and cost-effective tool for HAP and VOC compliance. of public meetings. TBF Environmental Technology Inc., a leader in the development of green industrial solvents, announced that the South Coast Air Quality Management District (SCAQMD) of California has approved and certified TBF Environment Technology Inc.'s leading solvent ZemaSol as being Volatile Organic Compound (VOC)-exempt and containing no hazardous air pollutants or ozone depleting materials, … In the SCAQMD regulations, such as Rule 1107 they are often referred to as "exempt" solvents or "exempt" compounds. Rule 1122 and Rule 1171 are cited as key rules to use in determining eligibility for a Clean Air Solvent Certificate (see below). Unlike other VOC-exempt solvents, TBAC has an intermediate evaporation rate and broad solvency for coatings resins, making it a more useful formulation tool for a variety of VOC-compliant industrial coatings as well as thinners and cleanup. IPA is widely used for handwipe cleaning applications – no longer compliant in places such as California, especially in South Coast Air Quality Management District . VOC exempt solvents are organic compounds that are exempt from restrictions placed on most volatile organic compounds in the United States. As per section 5.5 of the Standard, solvents that can Certified Clean Air Solvent Products and Companies. The South Coast Air Quality Management District (SCAQMD) is the local air quality regulator for the Los Angeles basin. • is 0 VOC and NPRI-exempt (SCAQMD Ultra low VOC 1.13 g/l). EPA will not declare a solvent blend VOC-exempt, only pure compounds. This class currently includes acetone, dimethyl carbonate, methyl acetate, parachlorobenzotrifluoride, tert -butyl acetate, and propylene carbonate. cleaners and VOC-exempt solvents that meet the VOC requirements of the rule are being used in most degreasing applications. ShiraSol meets all regulatory guidelines for emission of Volatile Organic Compounds. The entire list of VOC content limits for products can be accessed at this site. Note: If a manufacturer claims Rule 1113 compliance, it should be registered under SCAQMD Rule 314 and pay the appropriate fee. However, SCAQMD Rule 102 includes VOC-exempt products which may or may not be listed as VOC-exempt by the EPA. Should I or should not subtract the f exempt compounds of the VOC content? A Clean Air Solvent is defined under Rule 102: “CLEAN AIR SOLVENT is a VOC-containing material used to perform solvent cleaning, solvent finishing, or surface preparation operations or activities which: (A) Contains no more than twenty-five (25) grams of VOC per liter of material, as applied; (B) Has a VOC composite partial vapor pressure less than 5 mm Hg at 20 oC (68 oF); (C) Reacts to form ozone at a rate not exceeding that of toluene; (D) Contains no compounds classified as Hazardous Air Pollutants (HAPs) by the Federal Clean Air Act, or Ozone Depleting Compounds (ODCs) and Global Warming Compounds (GWCs) as defined by the District; and (E) Has been certified by the District to meet the criteria stated in (A) through (D) according to test methods and procedures approved by the District.”. Soy Methyl Esters: These versatile solvent alternatives qualify as LVP-VOCs due to high boiling points. This confuses the categorization of chemical compounds and blends as “VOC-exempt”, and the VOC contents of products. On June 28, 2019, OEHHA added PCBTF to … DISCLAIMER: All cleaning products included in this list have been granted a Clean Air Solvent (CAS) certificate after passing a chemical analysis performed by the South Coast AQMD Laboratory using the most recent version of South Coast AQMD Method 313, Determination of Volatile Organic Compounds (VOC) by Gas Chromatography/Mass Spectrometry (GC/MS). SCAQMD is expected to delete the exemptions for TBAC for Industrial Maintenance and certain Auto Refinish Coatings later in 2018. Very low Maximum Incremental Reactivity (MIR) value of 0.097. Mineral spirits are commonly used in parts cleaning systems yet contain ~ 780 gm/l of VOC’s – well beyond many AQMD thresholds of 50-100 gml/l. SCAQMD has convened a working group to propose stricter regulations to come into effect in 2015 through 2019. However, Rule 1122 still provides a limited exemption, under section (k)(1)(D), that allows for the continued use of high-VOC solvents … Soy methyl esters (or biodiesel) can be used to replace or augment the need for more volatile solvents such as D-Limonene, while maintaining a product's bio-based profile. • has no ozone depleters or creators. SCAQMD Rule 1171 Solvent Cleaning Operations Safer Alternatives to Toxic Cleanup Solvents Workshop March 7, 2007. 11.4 Sample Analysis Criteria. low vapor pressure (LVP) solvents, currently considered exempt as a VOC by some methods, volatilize at ambient conditions nearly as rapidly as the traditional high volatility solvents they are meant to replace. s Consequently SCAQMD has developed the most comprehensive and strictest restrictions in the US on the content and emission of Volatile Organic Compounds (VOCs), a prime precursor to ground-level smog formation.
