Inspection Summary:
Site visit was conducted on October 23, 2018. Bradley Bennett, Thad Valentine and Danny Smith participated in the visit
and onsite rep was Ben Willis. After a brief overview discussion staff reviewed the outdoor areas of the site but did not tour
any of the indoor activities. Site was found to be generally clean and well maintained. There were some secondary
containment structures that did not have locked valves. One containment area had oil stored in open buckets and staff
noted the need for different handling of used oil. There were empty totes stored onsite and a dumpster behind the
maintenance/warehouse building that looked to have more than just office type trash. The laboratory area had very little
outside material, but there were open containers adjacent to the lab that contain the chemicals being tested or materials
that have been used and are now being held for sunlight treatment prior to being used for irrigation in the greenhouse. These
materials could overflow during rain events.
During the site visit the water level of the pond system was observed to be very low. The facility had indicated there was no
discharge from the ponds and that the ponds were lined. It does not appear that there is the potential for evapotranspiration
that would account for the low water level. Onsite staff offered that there were muskrats that bored holes that could explain
some loss of volume? Need to continue to evaluate this process to determine where the water volume is going. Could
create groundwater issues. Hopefully the monitoring requested and supplemental monitoring by DWR can assess any
impact.
Staff pointed out monitoring locations for the facility rep onsite (Ben Willis). There are four outfalls and one in -ditch location
that staff requested monitoring for. The first two outfalls (001 and 002) are on the west side of the property near the shop
area. Outfall 003 is along the access road leading to the laboratory area where the lab area drains back into a conveyance.
Outfall 004 is the discharge point from the riser below the pond system. The in -ditch location (005) is below the last outfall
from the pond system and will help assess the overall impacts from the facility for DEMLR and DWR. See Staff Report in
LF for aerials noting the approximate locations.
