Air pollution aspects of hazardous waste disposal in Texas

Abstract

A case study of the review technique f o r toxic and odorous compound impacts in the atmosphere from proposed hazardous waste disposal facilities in Texas.

Air Quality Aspects of Hazardous Waste Landfills

“…The main factor influencing dust production is the vehicle speed: i.e., a reduction of 33% in dust emissions results from speed reduction from 30 to below 20 miles/hr; Bilsky (6) noted that the Texas Air Control Board proposed to limit truck speeds to 15 miles/hr. Beyond this, paving, grading, watering and adhesive or chemical suppression can be used on the roads.…”

“…The basic equation used in the calculation of the apparent diffusion coefficient of VOCs through soil is: DS = D0 (Pa10/3pT2) (6) *TLV or the threshold limit value is the maximum permissible time-weighted average concentration allowed for a normal 8-hr workday or 40-hr workweek to which nearly all workers can be exposed, day after day without ill effects. Springer et al,(43) noted that NA appears in two parts of the equation, so one must estimate it initially using the following expression: Where D0 = vapor diffusion in air Pa = soil-cap air filled porosity (i.e., porosity of moist soil) Pf = total porosity of the soil-cap (dry basis) Having the following diffusion term, one calculates the flux rate as Monitoring of the particulates is accomplished using high-volume air samplers to draw air at a controlled flow rate (typically 40 ft3/min) through filter paper.…”
