RCRA REVISION CHECKLIST 79

Organic air Emission Standards 
for Process Vents and Equipment Leaks
55 FR 25454-25519
June 21, 1990
(HSWA Cluster II)

Note:  The Federal Register addressed by this checklist is the first of a multiphased regulatory effort to control air emissions at new and existing hazardous waste treatment, storage and disposal facilities (TSDFs).  On April 26, 1991 (56 FR 19290; Revision Checklist 87), a technical amendment for this rule was published.  States are strongly encouraged to adopt the technical corrections at the same time the Revision Checklist 79 provisions are adopted.
