Grand Blvd.) and the city of El Segundo at a cost of over $723,000. • Continuous fence line monitoring data is available at: htta://www.lacitvsan.or2/hv Perlonalr. Reasons For Primary Tank Odors • Preliminarily treated wastewater flows through the primary sedimentation tanks to further separate solid materials over a 2 hour period. This slow moving wastewater allows solids to settle, but also releases gas or odors. • Tank covers allow this released gas to be collected by the odor control system, scrubbed and polished before the air is released. • All corroded and broken covers at Hyperion have been replaced. The project was completed in June 2024. Covers have a lifespan of 15 years. • Factors such as wind direction, wind velocity, and temperature impact the dispersion rates of odors into the community.

In April 2024, LASAN developed a new system for Hyperion updates sent to the public via email. These changes were made with the intention to make email updates more straightforward with the option to get information at a glance. Every email update now features a `tour" of new features so residents can become familiar with the system. The bottom of each ema# contains details about the color coding system. Hyperion update emails have a new Took! Take a tore of some of our tmw features below. Caloe-coding will let you know right away what type of activity a being reported In each eman.

Please note that residents MUST call the dedicated Hyperion hotline number provided by LASAN to be able to receive these reports; calls to AQMD or any other agency do not trigger this response by LASAN. of ` •4l1 •� 4 11 M U) c <a a E U 40 `0 v O w 0 20 E 3 Z HWRP Odor Complaints 65 62 56 42 45 43 36 35 29 t 26 253� 27 .-I —4 .-1 -1 .-1 -1 r-I ri -1 a-4 rq —4 N N (V (V N N N (V N N N (V M M M M M M M M M M M M-zt ItT IqItT 11* TTI.:T N N N N N N N N N (V N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N N 0000000000000000000000000000000000000000000 N N N N N N N N N N fV fV N N fV N N N N N N N N N N N N N N N N N N N N N N N N N N fV N \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ Ii e-1 c-i ci a--1 a--1 11 a--1 r-I r-I a --I r-I ei r-1 c-1 r-1 r-1 a--1 r-1 a-i r-I a-i \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ ri N M 111 l0 h 00 Q1 O ci N ci N M I.f1 lD I� W MO r-I N r-I N M 0 lD I� 00 MO i N r-IN M V1 lD I� ri t-i r-I r-I r-I ei � -I � -I4 r -I Date (mm/dd/yyyy) 12 100% inITATION WATER zero waste • zero wasted water RECYCLING Open Discussion m■ = UU @LACITYSAN Thank you'. lacitysan.org/recycledwater sanrecycledwater@lacity.org LFw r o n 100% ITATION WATER c °' .,a RECYCLING ZCfO W� !il0 LC�O Wil51C C7 WlIL`r
