Field Activity Update, October 14, 2019

Field work at the Ascon Landfill Site during the week of October 14 is planned to include:

  • Continued installation of 16-foot tall air monitoring stations inside Ascon to replace stations near the 16-foot barrier fence
  • Dust and odor mitigation measures continue to be implemented
  • Air quality monitoring continues
  • Weed abatement and removal as necessary
  • “Winterizing” field activity to prepare the Site for the winter rainy season by implementing best management practices for stormwater management, in compliance with Santa Ana Regional Water Quality Control Board permit
  • 24-hour onsite security continues

The new AES power plant near Newland Street and Pacific Coast Highway southwest of Ascon continues to test fire the gas turbines for the new Huntington Beach Energy Project. The test firing started on October 3. The first unit has completed the Steam Blow phase and the second unit will begin initiating “first fire”. Both units will be tested concurrently after the second unit completes test firing.

This is a visible activity for the power plant in southeast Huntington Beach—with noise and odor—and not associated with Ascon.

Update from AES: During this process, natural gas is combusted in the gas turbines to produce high pressure steam which cleans the main lines/pipes.

Noise: The Steam Blow phase can last from about one to two weeks. Steam blows can be expected 24-hours per day, with open air Steam Blows intermittently between the hours of 8 a.m. and 6 p.m. AES reports a loud hissing sound will be heard during open air Steam Blows.

Yellow/Light Orange Plume: AES reports the yellow/light orange plume vented from the new stack is part of the commissioning process and is due to “oxides of nitrogen”.

Frequently Asked Questions: Test Results for Swimming Pool Water at Edison High School

Frequently Asked Questions: Test Results for Swimming Pool Water at Edison High School

Did they find benzene in the swimming pool water at Edison High School?

No, benzene was not detected in the pool water at Edison High School. Benzene is listed as a Laboratory Control Sample (LCS) on the test results.

What is a Laboratory Control Sample?

A Laboratory Control Sample is used as part of the laboratory quality control procedures to assure testing is properly performed and that test results are reliable. Chemicals in defined amounts are included in the LCS to confirm the testing equipment is working properly. The chemicals used in the LCS are prepared and certified by an accredited outside agency.

The laboratory that conducted the test of the swimming pool water for the City of Huntington Beach used the EPA 500 Series Method, a method designed to identify and quantify organic compounds in municipal drinking water in compliance with the Safe Drinking Water Act.

Are there chemicals in the pool water that exceed safe levels?

The testing conducted by Sierra Analytical—an environmental laboratory certified by the Department of Health Services—found no chemicals that exceeded drinking water standards. Drinking water standards are known as Maximum Contaminant Levels (MCLs) and listed in Title 22 of the California Code of Regulations.

Field Activity Update, October 7, 2019

Field work at the Ascon Landfill Site during the week of October 7 is planned to include:

  • Installation of 16-foot tall air monitoring stations inside Ascon to replace stations near the 16-foot barrier fence
  • Dust and odor mitigation measures continue to be implemented
  • Air quality monitoring continues
  • Weed abatement and removal as necessary
  • Potential for field activity related to winter rainy season best management practices for stormwater management, in compliance with Santa Ana Regional Water Quality Control Board permit
  • 24-hour onsite security continues

Final remedy 16 foot AQ ladders October 2019

Taller air monitoring stations are being installed in the interior of Ascon near the 16-foot barrier fence, with additional safety measures for the environmental technicians who climb the stations to collect data.

The new AES power plant near Newland Street and Pacific Coast Highway southwest of Ascon expects to start up the gas turbines for the new Huntington Beach Energy Project on Thursday, October 3. This is a visible activity for the power plant and not associated with Ascon.

AES explains:
“During ‘first fire’, natural gas is combined with air and ignited through a combustion process to rotate the gas turbines. The heat generated from this process is used to convert water into high pressure steam. Following a successful first fire, high pressure steam will be used to thoroughly clean the plant steam pipes to avoid damage to the steam turbine. During the Steam Blow process, steam will be released from a temporary pipe and vented to the atmosphere. This will create a large steam plume that will be visible for the duration of each steam blow.”

The new AES facility’s steam blows may be expected between 8 a.m. and 6 p.m. AES has provided more information about the Huntington Beach Energy Project commissioning and start up at http://www.renewaeshuntington.com/HBEP%20Commissioning%20and%20Start%20Up%20FAQ_rev8.pdf

Field Activity Update, September 30, 2019

Field work at the Ascon Landfill Site during the week of September 30 is planned to include:

  • Continued installation of 16-foot barrier fence along Magnolia Street
  • Temporary vehicle lane and bike lane closure on Magnolia Street, during the hours of 9 am to 3 pm
  • Dust and odor mitigation measures continue to be implemented
  • Air quality monitoring continues
  • Weed abatement and removal as necessary
  • 24-hour onsite security continues

Final remedy fence Magnolia Street September 27, 2019
Installation of 16-foot barrier fence continues on Magnolia Street this week.

Construction of the of the 16-foot fence along Hamilton Avenue is completed. The fence installation continues on Magnolia Street and is expected to be completed by the end of September. We will be installing the fence at the northeast intersection corner at a later date. This is due to the limited space between the edge of the landfill and the intersection signal, which requires a small excavation action to allow placement of the concrete base for fence panel installation.
