Port-Wide Sewer System Management Plan(SSMP) - Port of Oakland

3. The facility has caused or contributed to collection system blockages resulting in
maintenance requirements or sewage spills.
Each FSF with a grease interceptor is required through their WDP and EBMUD Ordinance
No. 311A-03 to clean their interceptor on a regular basis to ensure its proper operation. At a
minimum, each interceptor must be cleaned once every three months and the grease must
be disposed of by an EBMUD approved grease hauler (see Section 8.2.2).
The Port is becoming very proactive in requiring new FSFs in the airport to install large
grease interceptors. A large grease interceptor for the new Chile’s Too was recently
installed. Additionally, grease interceptors will be constructed to service two new food
courts and the new Silver Dragon restaurant. This approach is consistent with the EBMUD
interceptor requirements and the intent of the GWDRs.
8.2.5 Best Management Practices
EBMUD has developed nine separate BMPs related to FOG. The BMPs are summarized in
Table 8.2 and are developed primarily for FSFs, which are the primary discharges of FOG
within the Port service area. Certain BMPs, however, do have a more universal
applicability. A flyer containing the information presented in Table 8.2 is also available on
the EBMUD website.
8.2.6 Inspection and Enforcement Procedures
In order to avoid redundancy and save time and cost to the Port, FOG Control Plan
recommends that all FOG inspection and enforcement actions be completed by EBMUD
through their existing FOG control program. A partnership with Port personnel may be
required at the Airport and Maritime facilities since security clearance requirements could
hinder EBMUD personnel from performing this function. Port staff could take on
responsibility for inspecting facilities at the Airport or Maritime areas, or escort EBMUD staff
on these inspections.
8.2.6.1
Inspection
The inspection procedures are based on a system-wide monitoring approach with
increased monitoring targeted at known “hot spot” areas, as summarized below:
• Hot spot areas. For this group of inspections, the Port identifies the locations of
grease-related SSOs or blockages to EBMUD. EBMUD then schedules targeted
inspections for dischargers upstream of the “hot spot” to identify the most likely
source of the problem. Accelerated interceptor maintenance schedules or interceptor
installations are then required as necessary to mitigate the issue.
• Non-hotspot areas. Inspection is performed routinely at all FSFs during the permit
period (at least once during each permit period). EBMUD inspectors verify that
required routine maintenance for grease traps and interceptors is being performed in
