DID YOU KNOW
A Stormwater Pollution Prevention Plan (SWPPP) guides current work at Ascon as we enter the winter season. Implementation is overseen by a Qualified Stormwater Practitioner on the Ascon team. The SWPPP is enforced by the City of Huntington Beach and Santa Ana Regional Water Quality Control Board.
As part of the SWPPP:
- The Site is inspected before forecasted major rain events
- City of Huntington Beach inspects onsite stormwater best management practices on a regular basis
- Ascon operates under the California General Construction NPDES permit and the Site SWPPP that allows for stormwater discharge offsite
- Stormwater discharge is tested following designated rain events per requirements of Santa Ana Regional Water Quality Control Board

ACTIVE WORK: A crew of workers will be at the Site to maintain plastic lining and sandbag anchors and to install a taller air monitoring station by the new northeast corner fence. You may see the arrival and departure of a skid steer and water tank, as well as pickup trucks.
SECURITY: 24-hour onsite security continues. Security may not be visible at the entrance gates. The Ascon security personnel are primarily within the Site conducting daytime and nighttime patrols of the 38-acre property. In addition to 24/7 onsite security, there are regular visits by air quality technicians, Site inspectors and Site maintenance personnel.
- DTSC continues its ongoing weekly inspections of Ascon.
- City of Huntington Beach continues its regular stormwater inspections of Ascon.

The California Department of Toxic Substances Control (DTSC) has permitted a brief pause on daily air sampling and monitoring both onsite and at offsite locations to allow our personnel to be with their families over the holidays, beginning Wednesday, December 23, at approximately 7 am. The air sampling and monitoring will resume at approximately 7 am, Monday, January 4.

Work at Ascon is being conducted under Site safety protocols regarding COVID-19.
