Hyperion update: staff to review enzyme proposal after 64 AQMD odor complaints; plant manager search to be refiled
Summary
A staff member reported that Source Technologies will send a proposal for an enzyme product to reduce odors at the Hyperion facility; AQMD logged about 64 odor complaints last month tied to a Jan. 8 power outage. Sanitation general manager Barbara Romero said the plant manager position will be reposted after no viable candidates were found.
A staff member provided an update on Hyperion wastewater operations, saying a company called Source Technologies will submit a proposal and cost estimate for an enzyme product intended to reduce odors at the plant.
The enzyme product, the staff member said, has been used in wastewater treatment plants on the East Coast and would be applied to the water before it reaches plant processes, rather than replacing the plant’s existing scrubber technology.
The update matters because the South Coast Air Quality Management District (AQMD) recorded about 64 odor complaints in the last month, the staff member said, and investigators flagged a fence-line spike in readings tied to a power outage on Jan. 8 at about 3 a.m. The facility used emergency backup power during the outage and was fully back online after a reboot on Saturday, Jan. 11, the staff member said.
"Long story short is they are gonna provide us with a kind of a proposal and and potential cost estimates that we can take back to Hyperion for consideration," the staff member said, describing the outreach from Source Technologies as originating after a representative saw coverage in the Los Angeles Times. "This is this actually goes into the water before it goes into the plant and supposedly eliminates odor."
The staff member also reported that Barbara Romero, identified in the update as the general manager of sanitation, said the department was unable to identify a viable candidate for the new plant manager position and will repost the vacancy. The staff member said they will follow up on the Source Technologies proposal and will share information about a postponed AQMD town-hall meeting; the staff member recalled the follow-up was scheduled about six months from the last meeting.
The remarks were presented as an operational update rather than a formal action item; no vote or formal decision was recorded in the transcript. The next steps described were staff follow-up to obtain the vendor proposal and for the sanitation department to relaunch recruitment for the plant manager post.
