Hyperion Treatment Plant — City of LA methane zone project update

October 18, 2011

Terra-Petra’s Deputy Methane Barrier Inspector Richard McClanahan was on site at the City of Los Angeles’ Hyperion treatment plant in Vista Del Mar (CA) this past August to inspect the installation of Epro System’s Ecoline-S  (methane barrier product) and witness the barrier smoke test to be able to issue a LADBS Certificate of Compliance.

The project is in the City of Los Angeles Methane Zone and therefore requires the LADBS Certificate of Compliance before the membrane may be covered or back filled.
