The next phase of the cleanup of contamination at the Balloon Track in Eureka is approaching. But in 2024, the first phase of a cleanup began with debris removed and defunct train cars booted from where they sat for decades. Now the second phase is being pursued, which involves removal and testing of dirt in drainage ditches for hazardous materials, according to Eureka planning documents. According to a staff report, approximately 355 tons of historic bunker sand, about 56 tons of contaminated soil and about 109 tons of solid waste were removed. A hearing is Friday at 11 a.m. to consider authorizing some tweaks to the original permit and approval of the second phase.
