RCRA REVISION CHECKLIST 85

Burning of Hazardous Waste in
Boilers and Industrial Furnaces
56 FR 7134-7240
February 21, 1991
(RCRA Cluster I, HSWA and non-HSWA provisions)

1)  There are numerous typographical and technical errors in the final rule addressed by this checklist; where they are obvious, we have noted them.  On July 17, 1991 (56 FR 32688; Revision Checklist 94) extensive corrections were made to the final rule addressed by this checklist because of the many typographical and other errors found in the February 21, 1991 final rule.  The Agency also published a second technical correction on August 27, 1991 (56 FR 42504; Revision Checklist 96), which reversed the revisions to 265.112(d)(2), 265.113(a) and 265.113(b) made by the final rule addressed by this present checklist, which contains these revisions as published in that February 21, 1991 (56 FR 7134) final rule.  States are cautioned not to make the corrections to 265.112(d)(2), 265.113(a) and 265.113(b) as requested by this checklist.  Otherwise those corrections will have to be undone when Revision Checklist 96 is applied for.  Finally, Revision Checklists 111 (57 FR 38558; August 25, 1992) and 114 (57 FR 44999; September 30, 1992) made several technical amendments to the BIFs rule.  Because of the extent of the technical corrections made to the rule addressed by Revision Checklist 85, States are strongly encouraged to use the Consolidated Boilers and Industrial Furnaces Checklist, which consolidates this present Boilers and Industrial Furnaces rule with subsequent revisions made to it.  A Consolidated Checklist which consolidates all final BIFs rules through December 31, 1991 (i.e., Revision Checklists 85, 94, 96 and 98 (56 FR 33874; September 5, 1991) is currently available on the SRPB Electronic Bulleting Board System.  That consolidated checklist will be part of SPA 12.  The consolidated checklist will be updated as part of subsequent SPAs as additional final rules addressing the BIFs rule are promulgated.  For example, a Consolidated Checklist which consolidates changes to the Federal code through June 30, 1993, including Revision Checklists 85, 94, 96, 98, 105 (57 FR 27880; June 22, 1992), 111 (57 FR 38558; August 25, 1992) and 114 (57 FR 44999; September 30, 1992) will be developed as part of SPA 14.

2)  States applying for Revision Checklist 85 are urged to adopt required Revision Checklists 94, 96, 111 and 114 changes at the same time the requirements addressed by Revision Checklist 85 are adopted.  States that have already adopted the provisions addressed by Revision Checklist 85 are strongly encouraged to apply for the Revision Checklists 94, 96, 111, and 114 provisions as soon as possible.

3)  Note that on September 5, 1991 (56 FR 43874; Revision Checklist 98), an administrative stay was published affecting this final rule, by delaying when the permit standards become effective for coke ovens burning certain hazardous wastes from a coke by-products recovery process.  The changes addressed by Revision Checklist 98 are optional.  However, the final rule addressed by Revision Checklist 105 (June 22, 1992; 57 FR 27880) removed the September 5, 1991 administrative stay.  Thus States should either not adopt the administrative stay or, if they choose to adopt the stay, state in their regulations that this stay ends on June 22, 1992.

4)  The regulations addressed by this checklist typically do not make a distinction between the various types of burning devices.  However, the provisions in the regulations as they apply to sludge dryers, carbon regeneration units, infrared incinerators, and plasma arc incinerators are non-HSWA requirements, while the regulations as they apply to all other types of burning devices are HSWA provisions.  EPA will implement the HSWA requirements in authorized States until the States modify their programs and such modifications are approved by EPA.  The non-HSWA requirements are applicable only in those States that do not have authorization.  In authorized States, the non-HSWA requirements will not be applicable until States revise their programs to adopt equivalent requirements under State law.
