Air Emissions Species Manual, Volume 1: Volatile Organic

In an effort to update the available speciated PM profile data base, EPA conducted studies to update the "Receptor Model Source Composition Library" (EPA-450/Kefid2) and produced a revision entitled "Air Emissions Species Manual - Volume II, Particulate Matter Species Profiles" (EPA-450/2- 88-003b).

Emissions from the Cement Industry - State of the Planet

May 09, 2012 · Emissions from the Cement Industry. A single industry accounts for around 5 percent of global carbon dioxide (CO 2) emissions. It produces a material so ubiquitous it is nearly invisible: cement. It is the primary ingredient in concrete, which in turn forms the foundations and structures of the buildings we live and work in, and the roads and

Documentation For Developing The Initial Source Category List

Speciation profiles distinguish the chemical constituents within the total VOC or PM emissions. By linking each speciation profile with an SCC, estimates of the HAP constituents emitted from a source category were determined. Each speciation profile has an associated data quality rating ("A" through "E").

How is Asphalt Made? A Look Inside the Manufacturing

11.1 Hot Mix Asphalt Plants 11.1.1 General1-3,23, 392-394 Hot mix asphalt (HMA) paving materials are a mixture of size-graded, high quality aggregate (which can include reclaimed asphalt pavement [RAP]), and liquid asphalt cement, which is heated and mixed in measured quantities to produce HMA. Aggregate and RAP (if used) constitute over 92 percent

Hot Mix Asphalt Emission Assessment Report | Air Pollution

Additionally, adjusted data for a variety of HAP's were used to develop ratios of the HAP pollutant to either organic PM or TOC (speciation profiles). These speciation profiles are applicable to load-out emissions and yard emissions. 2.2.4 Silo Filling

An assessment of important SPECIATE profiles in the EPA

Jun 15, 2019 · The most prominent PM 2.5 emission profiles are composite profiles derived from Reff et al. (2009), who created these category-specific speciation profiles based on the median of multiple high-quality profiles that were already in the SPECIATE database. On a national scale, the three most prominent profiles are Wildfires – Composite
