Volatile Organic Compounds Sample Clauses
The 'Volatile Organic Compounds' clause defines the standards and restrictions regarding the use, presence, or emission of volatile organic compounds (VOCs) within a project or property. Typically, this clause sets limits on the types and quantities of VOCs that can be used in materials such as paints, adhesives, or cleaning agents, often referencing regulatory thresholds or industry best practices. Its core function is to ensure compliance with environmental and health regulations, thereby minimizing harmful emissions and protecting occupants and the environment from potential hazards associated with VOC exposure.

Volatile Organic Compounds. Analyses for volatile organic compounds (VOCs) were performed on all the soil and groundwater samples with the exception of surface soils. In addition, 17 soil vapor samples from 13 vapor well▇ ▇▇▇ated throughout the mound and panhandle were analyzed for selected organic gases and vapors. Consequently, VOC analyses performed on non-refuse fill area media included 10 soil and 3 shallow groundwater samples; no VOCs were detected in any of these samples. The panhandle sampling media included 3 soil vapor samples. 3 subsurface soil samples, and 4 groundwater samples (one shallow and three deeper, which includes one repeat sample from one of the deeper well▇). ▇oil vapor sampling in the panhandle area indicated the general absence of volatiles, with detected compounds being the same as those detected in the trip blanks. Similarly, no VOCs were detected in the soil samples. The shallow groundwater sample yielded a few volatiles (97 ppb toluene, 48 ppb ethylbenzene, and 80 ppb total xylenes); one of the deeper groundwater samples (P-1B) yielded 7 ppb 1,1,1-trichloroethane and 10 ppb trichloroethene. Repeat sampling of well P-1B failed to detect these contaminants. The refuse mound area had a total of 14 soil vapor samples, 7 subsurface soil samples, and 4 groundwater samples (2 shallow and 2 deeper). The soil vapor sampling indicated the presence of a number of landfill gases. However, vinyl chloride was not detected. No VOCs were detected in the soil samples. The shallow groundwater, like that of the panhandle, yielded detectable levels of a few volatile compounds (6-40 ppb toluene, 16-24 ppb ethylbenzene, and 12 ppb total xylenes). Neither of the two deeper mound groundwater samples had detectable VOCs. Off-Site VOC sampling consisted of three groundwater well samples south of the site (two deeper samples from UCP-1 and one from shallow sample from UCP-2) and one shallow well sample northeast of the site (MV-3). The deeper well sample revealed trace levels of 1,1,1-trichlorocthane (6 ppb) and trichloroethene (7 ppb) when first sampled; these findings were not substantiated by repeat sampling. The shallow well samples revealed no VOCs. The soil vapor sampling indicates the presence of a variety of volatile landfill gases present in the mound area of the site at relatively low concentrations (less than 1.0 ppm). McLaren's groundwater sampling results are consistent with prior sampling performed by Levi▇▇-▇▇▇▇▇▇ (▇▇89 a,c) in that no VOCs were detected in the non-...
Volatile Organic Compounds. Product offerings must be in compliance with stringent emission levels for volatile organic compounds in accordance with ANSI/BIFMA e3-2014 Furniture Sustainability Standard, Sections 7.6.1 and 7.6.2 as such standard may be updated or superseded from time to time, using either the concentration modeling approach or the emissions factor approach.
