Appendix A
Calgon Carbon Corporation General Carbon Acceptance Criteria for Reactivation

The following tabular material provided by Calgon Carbon Corporation shows criteria for determining whether nonhazardous or RCRA-regulated granular activated carbon is suitable to accept for return for reactivation. Note the following definitions for acronyms used:

BSP Big Sandy Plant

BLP Blue Lake Plant

NIP Neville Island Plant

TEQ toxic equivalency (amount of 2,3,7,8-TCDD [2,3,7,8-tetrachlorodibenzo-p-dioxin] with toxicity equivalent to a complex mixture of 210 dioxin and furan isomers with four to nine chlorine atoms found in flue gases.)

RTM-10 Research Test Method (in-house designation for Determination of Ignitability Characteristic under RCRA for Spent Activated Carbon Test Method)

CALGON CARBON CORPORATION ACCEPTANCE CRITERIA

Criteria for Return for Reactivation of Non-Hazardous Granular Activated Carbon (GAC), which must be met:

Characteristic/Property

Limits of Acceptability

Size

Greater than or equal to 12 × 40 Mesh

pH Range

Greater than 2.0 and less than 12.5

Ignitable (per RTM-10)

Not Acceptable (Although BSP is permitted to receive D001 manifested material, they may not receive any spent carbon which exhibits the characteristic of ignitability.)

Instantaneously Ignitable (per RTM-10)

Not Acceptable

Dioxins

Not Acceptable at BSP or BLP

< 20 ug/kg TEQs at NIP

Polychlorinated Biphenyls (PCB’s)

< 50 mg/kg at NIP

Not Acceptable at BSP

1,2-Dibromo-3-chloropropane (DBCP)

Not Acceptable at Neville Island Plant or Big Sandy.

Radioactivity

Not to Exceed Background Level

Note 1: Spent Granular Activated carbon to be returned for reactivation shall be free of any foreign debris (rock, wood, metal, etc.) or extraneous impurities, free of oil and grease, easily wetted by water, and free-flowing.

Note 2: Acceptance for reactivation of spent carbon which has not been supplied by Calgon Carbon Corporation must be investigated on a case-by-case basis.

 DISPOSAL OF ACTIVATED CARBON FROM CHEMICAL AGENT DISPOSAL FACILITIES The following are GENERAL GUIDELINES for acceptability of spent carbon for reactivation. Spent carbons which do not meet these guidelines can usually be processed using special handling and/or blending techniques. Greater than 98% of the projects submitted for reactivation acceptance are approved. �owever, due to the spe- cial handling required, return of these carbons may be approved with limitations as to choice of reactivation facility, method, volume and/or frequency of return. The criteria listed below are guidelines. Because the regulations governing the operation of our reactivation facilities are complex and subject to change, Calgon Carbon Corporation must reserve the final right to reject the return of spent carbon to our facilities.
