Memorandum
TO: Andrew G. Pasmant, City Manager AGENDA
and City Council ITEM NO. 16
DATE: December 20, 2011
FROM: Shannon.A. Yauchzee
Public Works Director/City Engineer
SUBJECT: BKK LANDFILL SITE STATUS REPORT
RECOMMENDATION:
It is recommended Ahat the City Council receive and file this report.
DISCUSSION:
A. Long Term Plan and Agreement with State
The .two-year Consent Decree (CD) of March 9, 2006, between the Department of Toxic
Substances Control (DTSC) and the Potential Responsible Parties (PRP) Working Group
of about 27 companies continues with the Class I maintenance operations. This CD was
extended until March 2009.
STATUS: The DTSC agreed to a new, second Consent between the DTSC and the
PRP's. The terms and conditions of this new CD are virtually the same. The PRP's are
beginning an Engineering Evaluation / Cost Estimate (EECE). The EECA will determine
what is required to maintain the Class I cap and methane collection system for the future.
BKK Soils Gas Investiaation Bevond BKK Pronertv Boundar
The State of California Department of Toxic Substances Control (DTSC) has recently
informed the City of West Covina that they will be conducting a soil gas investigation to
determine if Volatile -Organic Compounds (VOCs), which may be toxic, are in the soil
beyond the BKK property boundary. This investigation will determine if soil gas VOCs
are present and if their concentration warrants further investigation. The work started in
November 2011 and should be completed in Early 2012. The majority of the drilling will
take place in the residential neighborhood located to southeast of the landfill, in the "M"
streets (Marlena, Maureen, Marcella, Miranda, Melissa, Magdalena, Maria, and Mary).
DTSC circulated the Fact Sheet (Attachment No.l) that was mailed to residences in
advance of the soil gas sampling.
B. Proposition 65 Notices
STATUS: Sampling continues to show no vinyl chloride gas emissions greater than the
0.05 ppbv (parts per billion by volume). Therefore, Proposition 65 Notices are not
required. Monitoring continues.
C. Class III Landfill Post -closure Activities
STATUS: Post -closure activities continue with routine monitoring and maintenance.
Local Enforcement Agency inspection oversight is still under contract. Inspections are
now on a twice per month basis as opposed to weekly. In addition, Public Works staff
meet and communicate with the Agency's personnel on a weekly basis.

F. USEPA Groundwater Contamination Corrective Action
Counsel for DTSC has indicated that DTSC plans to initiate implementation of the EPA
Groundwater Remedy, in whole or in part, and that Environ has recently been retained as
DTSC's contractor for this purpose. Staff has met several times with DTSC
representatives on this issue.
STATUS: DTSC and their consultants are developing a plan to install ground water (not
VOC) test_ wells and extraction wells in the Miranda Springs area (North of Miranda
Street) as the first step in a ground water remedy. The wells are located in an area owned
by the CDC and set aside as habitat. DTSC is working with Fish and Game to revise the
habitat permit in a way that would allow access to the site for the test and extraction
wells, but not subject the City to any liability for the possible reduction in habitat.

Why did you receive this fact sheet?
• This Fact Sheet has been developed to let you know about a soil gas investigation
scheduled to be performed in the vicinity of the BKK Landfills Facility (Facility).
• The investigation is being conducted to determine if volatile organic compounds
(VOCs) are present in soil gas beyond the Facility boundary.
• The Department of Toxic Substances Control (DTSC) is overseeing the soil gas
investigation.

Who is conducting the investigation?
The soil gas investigation will be conducted under the direction of DTSC. DTSC will use an outside contractor
to conduct the investigation.
When will the investigations be conducted?
The investigation will begin in mid September 2011.The results from these sampling events will help DTSC
determine whether additional sampling or further action is needed.
Why is the investigation being conducted?
In the past, the Facility accepted solid and liquid hazardous wastes, as well as municipal wastes, for disposal.
Some of these wastes included chemicals referred to as volatile organic compounds (VOCs). There is a landfill
gas system within the Facility's boundary that collects and controls the movement of landfill gases. However,
it is possible that some VOCs are moving into soil gas, either from contaminated groundwater or directly from
the Facility (see figure on next page.) Therefore DTSC wants to investigate.
Will you be inconvenienced by the investigation?
Background noise and disruption to traffic will be kept to a minimum. In areas where the investigation needs
to be undertaken on private property, access agreements with property owners will be requested.

Conceptual model of BKK Landfills Facility soil gas and groundwater migration
VOCs are chemicals that are used in products such as
made available. If any samples are collected on
paints, certain cleaning products, glues, and certain

fuels. VOCs have a chemical composition that makes

them tend to volatilize (evaporate) into gas.
you may see this soil gas sampling truck
The soil gas samples will be used to determine if
and lab in your neibourhood
VOCs are moving from the Facility and possibly
contaminating soil gas beyond the site. Soil is
porous, and soil gas occupies the open spaces,
between soil particles. VOCs can be present as
vapors in these pore spaces, and can be collected
and measured.
DTSC has already conducted some preliminary'
groundwater sampling beyond the Facility
"
boundaries. Results from that sampling show that
groundwater has been contaminated with VOCs that
originated from the Facility. This information helped
DTSC develop an approach for the soil gas
investigation. The potential movement of VOCs.,
from soil gas to air can be a concern for human
health.
How has DTSC prepared for these
investigations?

DTSC technical staff has worked closely with outside

workplan. The workplan identifies sampling,

samples to be analyzed, and how the data will be

managed.
How will the results of the soil gas investigation be
communicated?

results, a separate fact sheet with the results will be

What,does the soil gas investigation consist of?
• Installing either permanent or temporary soil gas
monitoring equipment for collecting soil gas samples
at depths of 5 to 15 feet.
• Collecting and analyzing the soil gas to show
how much (if any) and what kind of contamination
exists in soil gas.
• DTSC will use a mobile analytical laboratory that will
analyze samples the same day they were collected.
• The soil gas sampling procedure will use a sampling
truck and a support truck. The majority of sampling
will be conducted in the paved streets areas, and
should not significantly affect traffic.
The investigations described here will take time.
Additional information will be provided to the
community throughout the life of the project.
History of the BKK Landfills Facility
The Facility, located at 2210 South Azusa Avenue in
West Covina, operated as a municipal and hazardous
waste disposal site from 1962-1996. The Facility
accepted large volumes of liquid and solid hazardous
waste until the Class 1 landfill closed in 1988. The
municipal waste portion of the Facility
(Class 3 landfill) stopped accepting waste in 1996.
The BKK Corporation owned and operated the
Facility between 1976 and 2003. In 2004, the
BKK Corporation. notified DTSC that it did not
have sufficient funds to continue operating and
maintaining'the closed Class I landfill and
leachate treatment plant (LTP) beyond mid -
November 2004. DTSC began an emergency
response action the same month to ensure the
continued day-to-day maintenance of the Class I
Landfill, LTP, and associated equipment. BKK
has continued to maintain the Class III landfill.
In December 2004, DTSC issued an Imminent
and Substantial Endangerment Order to a
number of Potential Responsible Parties (PRPs)
(former customers and former owner), which
ordered them to take care of the Facility. Roughly 25
of the PRPs entered into a consent decree in 2006
which required them to maintain the Class I landfill
on a daily basis and undertake some special projects.
DTSC and the PRPs signed a second consent decree
in 2010 (which has a term of three years), which
requires the PRPs to evaluate the Class I landfill
infrastructure and continue essential day-to-day
operations, with oversight provided by the DTSC.
