Section 6 - Schedules and Procedures
6.1 Control Measures Maintenance
MSGP-2010 Part 2.1.1.3 requires that CMs identified in the SWPPP must be maintained
in effective operating condition. When COPAD or a co-permittee discovers a CM that is
not operating effectively, maintenance must be performed within 14 days or prior to the
next measureable storm event, whichever is sooner.
6.1.1 Co-permittee-Owned Control Measures
Regular inspection and maintenance of co-permittee-owned CMs, such as spill kits,
structural covers and oil/water separators, are the responsibility of the co-permittee.
Oil/water separators must be visually inspected on a regular basis and pumped out
when necessary. Oil/water separator owners are required to maintain maintenance and
inspection records for these structures. If necessary based on the types of discharge to
the separator, co-permittees are required to sample the material to be pumped for waste
profiling to ensure it is properly manifested, transported and disposed.
Where treatment devices, facilities or interceptors are used in direct connection to the
public storm drain system, those devices, facilities or interceptors shall be maintained
continuously in satisfactory and effective operation by the owner at their expense.
The following Control Measure shall be implemented at all oil water separators (OWS)
that discharge to the storm drain system:
(1) monthly inspection of inlet area and OWS chambers for releases, oil, trash, debris,
and oil accumulation
(2) monthly inspection of the OWS discharge point for releases or staining
(3) minimize stains, trash, debris, and non-stormwater to OWS inlet area
(4) remove the OWS contents (and re-filling with clean water) in the event that oil is
observed in the OWS single and/or final chamber.
Written records and documentation of all inspection, cleaning, repair, and maintenance
shall be provided at each annual stormwater inspection and maintained by the OWS
operator for a minimum of five years and made available to the City upon request.
Failure to prevent releases from the OWS to the storm drain will subject a co-permittee
to a Notice of Violation and may result in conversion of the OWS to a sump or require
additional engineering controls.
COPAD conducts quarterly routine and annual comprehensive facility inspections
(CFIs) of co-permittees’ facilities (see Section 6.3) to meet the inspection requirements in
the MSGP-2010 and to verify maintenance of co-permittee owned CMs. CM
maintenance identified during those inspections are discussed with the co-permittees at
