A list of HSACs follows, with corresponding HCCs to be handled at facilities. A segregated
storage area should be provided for each HSAC. (HCCs that should not be processed within a
facility are not included.)
1. HSAC A: HCCs A2, A3
2. HSAC C: HCCs C1, C2, B1, B2, C4, C5
3. HSAC D: HCCs D1, D2, D3, D4
4. HSAC R: HCCs R2, Z6
5. HSAC F: HCCs F1, F2, F3, F4, F5, F6, F7, F8, V4
6. HSAC L: HCCs C3, B3, M1, N1, P2, T4, T6, V1, V5,
V6, V7, Z1, Z2, Z3, Z4, Z5, Z7
7. HSAC T: HCCs K2, T1, T2, T3, T7
8. HSAC P. HCCs P1
B. Incompatible storage areas must be segregated. Segregation within compatible storage areas
is detailed in Appendix C.
4.36 Holding Area Procedures
A. Materials brought to recoupment facilities should be segregated and placed, according to
HCC, in a compatible holding area as outlined previously in this section.
B. Materials that are leaking or likely to leak must be placed in spill pans or overpack drums
before being stored in the recoupment facility.
C. Personnel should simultaneously handle compatible materials only. Incompatible materials
must be segregated during all phases of recoupment operations. Segregation within compatible
holding areas defined by HSACs C and L is required as follows:
1. HSAC C: HCCs C1, C2, C4 and C5 a minimum of 6 feet from HCC B1, and B2.
2. HSAC L: HCC P2 a minimum of 6 feet from combustible/high flash materials (V4, V5,
V6).
D. A walkthrough inspection of the holding area by supervisory Personnel should be frequently
performed to detect actual or potential release of hazardous materials. If a release is discovered,
recoupment personnel should implement emergency procedures as directed in chapter 7 of this
publication.
