Final Mitigation Monitoring and Reporting Program (MMRP)

Los Angeles Harbor Department Section 2 Mitigation Monitoring and Reporting Program
LM RISK-2 Contamination Contingency Plan Lease
Measure.
The following contingency plan shall be implemented by the
Tenant to address previously unknown contamination during
demolition, grading, and construction:
a. All excavation and filling operations within the
boundaries of the construction area shall be observed for the
presence of free petroleum products, chemicals, or otherwise
chemically impacted soil (CIS). Deeply discolored soil,
suspected contaminated soil, or soil registering greater than 50
ppmv when measured with a photoionization detector (PID)
or organic vapor analyzer (OVA) shall be segregated from
clean soil. In the event unexpected suspected chemically
impacted material (soil or water) is encountered during
construction, the contractor shall notify the Los Angeles
Harbor Department's Chief Harbor Engineer and Director of
Environmental Management (EMD). Harbor Department
EMD personnel shall confirm the presence of the suspect
material and direct the contractor to remove, stockpile or
contain, and characterize the suspect material(s). Continued
work at a contaminated site shall require the approval of the
Chief Harbor Engineer.
b. A photoionization detector (or other similar devices)
shall be present during grading and excavation of suspected
chemically impacted soil.
c. Excavation of VOC-impacted soil (defined as soil which
registers a concentration of 50 ppm or greater of Volatile
Organic Compounds as measured before suppression
materials have been applied and at a distance of no more than
three inches from the surface of the excavated soil with an
organic vapor analyzer calibrated with hexane) will require
the Tenant to obtain and comply with a South Coast Air
Quality Management District Rule 1166 permit.
d. The remedial option(s) selected shall be dependent upon
a number of criteria (including but not limited to types of
chemical constituents, concentration of the chemicals, health
and safety issues, time constraints, cost, etc.) and shall be
determined on a site-specific basis. Both off-site and on-site
Timing: Prior to (contingency plan preparation and
approval) and during Project construction.
Methods: BNSF shall prepare a contamination
contingency plan approved by LAHD, and the plan shall
be included in bid specifications and leasing agreement.
Such procedures will be included in any bid
specifications for construction or operations personnel,
with a copy of such bid specifications to be provided to
LAHD, including a completed copy of its operations
emergency response plan prior to commencement of
construction activities. The contractor(s) shall adhere to
these specifications and throughout construction phases.
Implementation: BNSF and Tenants through
Construction Contractors
