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.
Page Two

2. WAC 173-303-808 pertaining to land treatment and the requirement to demonstrate adequate neutralization of land treated

materials.

Land Disposal and Groundwater Monitoring

This section is amended to be identical to EPA with the exceptions that

land disprisal of extremely hazardous waste (EHW) is not allowed (however,

land treatment is allowed), and new surface impoundments which will hold

liquid EHW will be required to have both a double liner system and either

groundwater or unsaturated zone monitoring.

Technical Amendments

General typographical and grammatical errors corrected for clarification

and to ensure equivalency with EPA.

Moderate Risk Standards

These amendments are for the purpose of lessening the level of regulation

on certain activities and wastes that repre$ent a moderate threat to human

health and the environment. These standards pertain to wastes that are

not regulated by EPA and that are designated a dangerous waste only (i.e.,

non-EHW) by the state.

Recycling Standards

These standards are essentially identical to EPA's new standards proposed

on April 4, 1983 and contain the following provisions:

1. Identifies solid waste.

2. Specifies that if a material is not identified as a solid

waste it is not regulated ..

3. Exempts certain recycling processes involving solid waste.

4. Sets up requirements for generators, transporters, and recyclers

of dangerous waste that are not exempted.

5. Prohibits accumulation of hazardous material without sufficient

use.

6. Establishes specific recycling requirements for:

A. Dangerous waste;

B. Moderate risk waste;

C. Characteristic or chemical products wastes;

D. Non-batch tolling agreements;

E. Reclaiming spend lead acid batteries.
