Final Initial Study/Mitigated Negative Declaration
Haynes Generating Station Sewer Force Main Project FN
• Objective 2. Facilitate the integration of the LADWP's HGS with LACSD's Long Beach WRP
through the construction of an interconnecting, 12 -inch sewer force main to facilitate
beneficial reuse of up to 2.841 MGD of combined industrial and on-site stormwater
discharges in compliance with Order Number R4-2022-0032 (NPDES No. CA0054119)_
• Objective 3. Maximize the use of LBUD's collection system and LADWP's existing power
easements to facilitate the placement of the Project elements.
• Objective 4. Annex LADWP's HGS into LBUD's and LACSD's District Number 3 service
areas, as required, and amend LBUD's and LACSD's Sphere of Influence (SOI), as required,
to incorporate the HGS property.'
Under the Project, a new sewer force main would be constructed that meets Ke LBUD's Standard
Drawings, Design Criteria for Potable Water Distribution System, and DeOn n Criteria for Sanitary
Sewer Facilities. The Project includes the construction of a new 12 -inch Iameter sewer force main
that would extend from LADWP's HGS to an existing 42 -inch LACKsewer main located at the
LACSD's Long Beach WRP. Figure 2-5 provides an overview oft Project components.
The Project would facilitate the beneficial reuse of up to 2.766 MGD of industrial wastewater
discharge and 0.075 MGD of on-site stormwater runoff (totaling 2.841 MGD) from the HGS for
treatment and distribution by LACSD's Long Beach WRP.

There are two very important pieces of information included in the
wastewater project study.
FIRST: (pg. 15) The pipeline route is different. It goes straight through
College Estates. Can any of you imagine approving a pipeline going
through College Park East when it could just as easily go on Lampson?
DWP is going through College Estates just because it's the cheapest route.
SECOND: (pg. 13) The project study gives the daily volume of wastewater
(reclaimed water study does not). Look at the calculations. The daily
volume of both pipelines is the same as adding more than 11,000 cars per
day. It's the same as driving 339 Army tanks over the bridge every day.
How much will the additional load and stress reduce the remaining
useful life of the bridge? How will its seismic safety be affected?
(The bridge is one mile from the Newport -Inglewood fault.) None of this is
mentioned in either project study. The DWP is only focused on building the
pipelines as cheaply as possible. They are completely ignoring the serious
risk to the structural integrity of the bridge.
PACIFIC PALISADES. That is exactly what happened in Pacific
Palisades. The DWP left the 117 million gal. reservoir empty for one year
because that was the cheapest way to repair its torn cover. They ignored the
incredible risk they were taking until the wildfire started --- and then it was
too late. The LA Mayor said the DWP never told her. She had no warning.
The DWP is following its standard procedure of ignoring risks and choosing
the cheapest alternative. Fortunately, you are receiving repeated advance
warnings from people with the most to lose. The danger to the bridge is real.
The numbers are facts, and the facts don't lie.
