摘要

The U.S. Environmental Protection Agency is providing background information that211u001esupports the use of Metro Machine Corporation's (MMC) compliant all position 211u001eenclosure (CAPE) plus air management system and regenerative thermal oxidizer 211u001e(RTO)(CAPE + RTO System) as an alternative means of limiting the emissions of 211u001evolatile organic hazardous air pollutants per volume of applied solids 211u001e(nonvolatiles). This document also explains how the authors arrived at the 211u001eoperating, recordkeeping, and reporting conditions that MMC must meet for 211u001eapproval. The add-on control system they used consists of a pollution capture 211u001eunit operation (CAPE) plus air management system and a destruction unit operation 211u001e(RTO). When operated according to the specified procedures, it will control 211u001eemissions to a level no greater than that from using coatings which comply with 211u001ethe limits in Table 2 of 40 CFR Part 63, Subpart II.
