Thepublic comment period is scheduled to end on December 21, 1983. After considering comments, and if major changes to the amendments are not necessary, the department intends to adopt the proposed rule changes by February 7, 1984. The final amendments will become effective thirty days after the adoption date. Permit Requirements Amendments to this section are necessary to assure equivalency with federal requirements. To be equivalent to EPA, WDOE's permit requirements and procedures require some reorganization and the addition of two new provisions: 1. WAC 173-303-807 pertaining to trial burns for incinerators and the requirement to demonstrate adequate destruction of incinerated materials.

Technical Amendments General typographical and grammatical errors corrected for clarification and to ensure equivalency with EPA.
