.. The Santa Ana Regional Water Quality Control Board (RWQCB) held a meeting on October 24 at
their Riverside office to review `rough data" from additional underground tank removals soil tests.
The City had previously requested additional testing points in Seal Beach Boulevard and pacific
Coast Highway to fully define the contamination plume in the area. The RWQCB has agreed with
that request and the environmental consultants are in the process of obtaining City and Caltrans
permits to accomplish the additional testing.

property:
o Monitoring well 8 was abandoned at the request of the Musso family and with the
concurrence of the Regional Water Quality Control Board.
o The fust round of groundwater monitoring was conducted, preliminary results indicate a
reduction in the contamination levels due to previous underground tank removals and the
use of oxygen -releasing compound (ORC)
o Removed 2 additional underground, 550 -gallon fuel tanks, both containing fuel product and
sludge. Placed additional ORC into the tank removal holes.
o Installed a new groundwater monitoring well closed to the boundary between the Jeong and
Musso properties, with the concurrence of the Regional Water Quality Control Board.
Additional work still to occur on the site:
o ORC to be applied at three additional locations on the subject property.
o ORC to be applied at 7 locations on the Musso property.
o Conduct the off-site contamination investigations on Seal Beach Boulevard and Pacific
Coast Highway upon receipt of Caltrans permits, probably within 45-75 days.
