Subject: [CPEO-MEF] PERCHLORATE: Rialto (CA) closure plan
SB County submits permit-closure plan for contaminated Rialto site

RIALTO - The San Bernardino County Mid-Valley Sanitary Landfill expansion on 20 acres in the north end of town remains a few years away as officials continue to study the extent of perchlorate contamination at a former hazardous waste storage and disposal site there. The Department of Toxic Substances Control is investigating the site at 2610 N. Alder Ave., once part of the 2,822-acre former Rialto Ammunition Back-Up Storage Point operated by the U.S. Army between 1941 and 1945, and taken over in 1966 by explosives manufacturer Broco, Inc.

According to the DTSC, before the county - which purchased the property in 1994 - moves forward with the expansion, it must meet requirements to discontinue a hazardous waste facility interim status permit granted to Broco in 1981.

Following a 1987 explosion at a nearby property, Broco moved north of the landfill without following protocol required under the permit, according to the DTSC.
