Portland Cement is the principal ingredient in concrete, which is used worldwide as the main building block of infrastructure construction as well as for commercial and residential structures. Air toxics, also referred to as hazardous air pollutants (HAPs), are those pollutants that are known or suspected to cause cancer or other serious health effects. Portland cement manufacturing is an energy intensive process in which cement is made by grinding and heating a mixture of raw materials such as limestone, clay, sand, and iron ore in a rotary kiln. The kiln is a large furnace that is fueled by coal, oil, gas, coke and/or various waste materials. The product (called clinker) from the kiln is cooled, ground, and then mixed with a small amount of gypsum to produce portland cement. The main source of air toxics emissions from a portland cement plant is the kiln. Emissions originate from the burning of fuels and heating of feed materials. Air toxics are also emitted from the grinding, cooling, and materials handling steps in the manufacturing process. Pollutants regulated under this rule are particulate matter, organic HAP, metals through the control of particulate matter, mercury, acid gases, and dioxin/furan. What is the compliance date for an "open clinker pile" at a portland cement plant that is subject to the NESHAP requirements that became effective on February 13, 2013?

True or False -- This pumping helps keep contaminants from reaching drinking water wells, wetlands, streams, and other natural resources. True False

True

Dispersion modeling uses mathematical formulations to characterize the atmospheric processes that disperse a pollutant emitted by a source. Based on emissions and meteorological inputs (Links to an external site.), a dispersion model can be used to predict concentrations at selected downwind receptor locations. These air quality models are used to determine compliance with National Ambient Air Quality Standards (NAAQS), and other regulatory requirements such as New Source Review (NSR) and Prevention of Significant Deterioration (PSD) regulations. These models are addressed in Appendix A of EPA's Guideline on Air Quality Models (also published as Appendix W (PDF) (Links to an external site.)(54 pp, 761 K, 01-17-2017) of 40 CFR Part 51), which was originally published in April 1978 to provide consistency and equity in the use of modeling within the U.S. air quality management system. These guidelines are periodically revised to ensure that new model developments or expanded regulatory requirements are incorporated. What is/are the EPA's preferred air quality dispersion models? Hint - look to EPA's Support Center for Regulatory Atmospheric Modeling (SCRAM) OCD - A straight line Gaussian model developed to determine the impact of offshore emissions from point, area or line sources on the air quality of coastal regions.

Vapor intrusion is the movement of chemical vapors from contaminated soil and groundwater into nearby buildings. Vapors primarily enter through openings in the building foundation or basement walls ─ such as cracks in the concrete slab, gaps around utility lines, and sumps. It also is possible for vapors to pass through concrete, which is naturally porous. Once inside the home or workplace, vapors may be inhaled posing immediate or long-term health risks for the occupants. In rare cases, the buildup of vapors, such as those from gasoline, may cause explosive conditions. Risks will depend on the types of chemical vapors and their concentrations, how much time people spend in the building, and the building's ventilation. Vapor concentrations will be ____________ indoors when windows and doors remain closed. lower therapeutic the same higher

Air sparging, on the other hand, pumps air underground to help extract vapors from groundwater and wet soil found beneath the water table. The addition of air makes the chemicals evaporate faster, which makes them easier to extract with another technology, such as SVE. soil vapor extraction monitored natural attenuation phytoremediation amendment dilution
