>>Below are some tables I developed of EPA's information plus a little

>>right now till 8/19  (Monday).  These are Maximum Achievable Control
>>Technology standards for hazardous waste combustors (cement kilns,
>>light weight aggregate kilns and hazwaste incinerators).
>>
>>MACT is supposed to be the equivalent to the best controlled source
>>for new waste combustors and to the average of the best 12% for
>>existing waste combustors.
>>
>>
>>The percentage numbers are from EPA's narrative on the standards.

>>The citation at the end is the applicable section of the Clean Air

>>Most hazardous waste is disposed of in cement plants (60-70%) who
>>win big with the proposed numbers.
