自1990年《清洁空气法》修正案通过以来，许多提议修改的设施已经评估了第三章对其计划的额外影响。该分析允许将BACT或LAER要求与第三篇最大可实现控制技术（MACT）的要求进行比较。本文为一家重型卡车制造商提供了一个案例研究，该制造商计划对使用水性材料的卡车喷漆设施进行扩建，以减少过程中的排放，而不是在烟囱处进行减排。

MANY FACILITIES PROPOSING MODIFICATIONS SINCE THE PASSAGE OF THE CLEAN AIR ACT AMENDMENT OF 1990 HAVE EVALUATED THE ADDITIONAL IMPACT OF TITLE III ON THEIR PLANS. THIS ANALYSIS ALLOWS THE COMPARISON OF BACT OR LAER REQUIREMENTS WITH THOSE OF THE TITLE III MAXIMUM ACHIEVABLE CONTROL TECHNOLOGYH (MACT). A CASE STUDY IS PRESENTED FOR A HEAVY TRUCK MANUFACTURER PLANNING A FACILITY EXPANSION FOR PAINTING TRUCKS USING WATERBORNE MATERIALS TO REDUCE EMISSIONS AT THE PROCESS RATHER THAN ABATEMENT AT THE STACK.
