3 Section A: Introduction and Purpose Sanitary sewers on the UC Berkeley campus and in the surrounding City of Berkeley, City of Albany, City of Richmond, and Lawrence Berkeley National Laboratory can occasionally overflow due to breaks or blockages in the sewer lines. These overflows can result in discharges of raw sewage and/or laboratory wastewater into surface water/storm drains and eventually into San Francisco Bay. In order to protect public health and the environment from raw sewage and any chemicals that may be contained in the sewage, a quick, coordinated response is needed to stop the source of the overflow and to eliminate the downstream migration of sewage. These procedures have been developed in conjunction with the City of Berkeley, City of Albany, City of Richmond and the Regional Water Quality Control Board to provide instructions for campus departments responsible for responding to sewage spills, in order to maximize the effectiveness of the control and cleanup of sanitary sewer discharges. These procedures are saved in electronic format on the EH&S server and are available on the EH&S website at: ehs.berkeley.edu. Section B: Scope These procedures apply to sanitary sewer spills that have been, or are threatened to be, released from UC Berkeley s three enrolled sanitary sewer systems (UC Berkeley CS, UC Berkeley Berkeley Global Campus at Richmond Bay CS, and University Village Albany CS). These procedures apply to all sewage overflows caused by a failure of the sanitary sewer system, which includes any system of pipes, pump stations, sewer lines or other conveyances, upstream of a wastewater treatment plant headworks used to collect and convey wastewater to a publicly owned treatment facility (WDR DWQ). Laterals and mains located on UC Berkeley property are all owned by UC Berkeley, unless otherwise specified in contractual agreements. Procedures caused by a failure of a plumbing fixture are not included in this response document. This document details procedures for response, spill cleanup, posting of public health warnings and agency reporting.

4 Section C: Sanitary Sewer System Description UC Berkeley CS The UC Berkeley CS is comprised of a network of pipes, sumps, pumps and manholes. This system dates back to the 1890 s and portions of the existing system may be over a century old. Blockages in sewer pipes can occur when pipes become obstructed by tree roots infiltrating systems or by debris (such as debris from construction or domestic activities, or pieces of broken pipe). If the flow rate is sufficient, sewage can backup from the blockage and eventually escape the sewer system at an upstream low point, such as a manhole or floor drain. In addition, potential up-gradient sources of sewage spills include City of Berkeley residential and commercial districts and the Lawrence Berkeley National Laboratory. The City of Berkeley sewer system is also old, dating to the 1880 s, and deterioration of pipes is exacerbated by the proximity of the Hayward Fault and associated ground movement. UC Berkeley Berkeley Global Campus (BGC) at Richmond Bay CS (formerly, Richmond Field Station) The Berkeley Global Campus at Richmond Bay is a satellite of the UC Berkeley campus, one of the 10 University of California campuses governed by the Regents of the University of California. The BGC sanitary sewer system connects with the City of Richmond sanitary sewer system. The Richmond Field Station portion of the BGC sewer system serves a population of 265. There is approximately 1.8 miles of gravity sewers and 1.3 miles of laterals.. University Village Albany CS The UVA sanitary sewer system connects with the City of Albany sanitary sewer system and serves approximately 3,000 people. There is approximately 1.7 miles of gravity sewers and 1.5 miles of laterals, all which are owned by UC Berkeley. A majority of the sewer system piping was constructed between 1980 to present.

5 SECTION D: AVAILABLE RESOURCES Multiple departments are responsible for responding to sewage spills at UC Berkeley. Those departments include: Office of Environment, Health and Safety (EH&S), Facilities Services (FS), Residential Student Services Programs (RSSP) and Berkeley Global Campus Operations (BGC Ops). All departments have personnel, materials, supplies and equipment to complete some or all of the response. Outside contractors are available to aid in the repair of the sewer system and cleanup of sewage. Following is a list of available resources: On-Campus Personnel Contact Information Department Name Business Hours After Hours EH&S (Environmental Protection and Dedicated Spill Response Team [DSRT]) (510) (510) University of California Police Department (UCPD) (510) (510) Facilities Services (Plumbers, Zone Plumbers and Laborers) (510) (510) Residential Student Services Programs (510) (510) Berkeley Global Campus Operations (510) (510) Contract Assistance* Type of Work Company Department Responsible for Contract Response / Repair Roto-Rooter FS / RSSP / BGC Clean Up Various FS / RSSP / BGC Sampling Cerco Analytical EH&S Sampling Tetra Tech EH&S * For phone numbers, see Attachment 1: Contractor Contact Information

6 Spill Response Equipment and Supplies Spill response equipment and supplies are located in various places on UC Berkeley property. In general: EH&S equipment and supplies are located at the Hazardous Materials Facility (HMF) and University Hall. RSSP equipment and supplies are located at the University Village Albany Grounds Yard and Clark Kerr Building 19 Plumbing Shop. FS equipment and supplies are located at 2000 Carleton Street and the Poultry Yard. BGC equipment and supplies are located at the Berkeley Global Campus - Richmond Field Station. For a detailed inventory, see Attachment 2: Inventory Personal Protective Equipment (PPE) For information on PPE needed to respond to a sewage spill, see Sewer System Management Plan Appendix D - Resources. In addition, EH&S provides additional in-person training to maintenance staff regarding environment, health and safety issues related to spills/sewage including the types of proper PPE to use in various circumstances. SECTION E: RESPONSIBILITIES Following are departmental responsibilities for sewage spill response: EH&S Responsibilities Notify FS (510) , RSSP (510) or BGC Ops (510) via the Call Center with information about spill and response needs, if initial notification to EH&S was not from either a FS, RSSP, or BGC Ops responder. Report spill to appropriate regulatory agencies. Post public health signs along affected areas, as needed. Contact sampling contractors for water quality monitoring or clearance samples as needed (see Attachment 3: Water Quality Monitoring Program Plan). Collaborate with FS, RSSP or BGC responder to ensure SSO is responded to properly and provide guidance to reduce environmental impacts. Submit reports to Regional Board, State Board and other agencies as necessary.

7 FS / RSSP / BGC Responsibilities Contact EH&S immediately when a sewage spill has been reported. Mobilize resources to stop the source of the sanitary sewer discharge. Contain the spill and barricade the area from public access. Contact outside contractors if any additional resources are needed for repair or cleanup. SECTION F: SEWAGE SPILL RESPONSE PROCEDURES Detailed sewage spill response procedures for specific departments have been provided in Section G: EH&S Response and Section H: FS/RSSP/BGC Response. However, if a large event occurs that disrupts campus operations, procedures outlined in the UC Berkeley Emergency Operations Plan (EOP) will be followed. The following are general procedures for sewage spill response: Upon notice or discovery of the sewage spill, notify the appropriate maintenance department. Contain the sewer overflow to the maximum extent possible by utilizing spill containment devices (examples: sandbags, portable dikes, storm inlet covers, etc.) to keep spills from entering the storm drain. Determine the location and cause of the overflow. Assessment may include an inspection of lift station pumps and downstream manholes. Stop the SSO or stop the cause of the SSO. Secure the affected area and post public health warning signs. Place barricades, cones, and/or caution tape to secure the site from public access. (See Section K: Public Health Notifications for triggers.) Remove contaminated residual from storm pipes and attempt to recover all sewage from the storm drain, if possible. Clean and sanitize the affected area(s) and ensure that chlorinated cleanup water is not discharged into the storm drain. Notify the appropriate agencies. Finalize the documentation for the incident by filling out the Sanitary Sewer Overflow (SSO) Incident Reporting Form. Review overall response with the responding parties. Standard Operating Procedures for specific events can be found in Attachment 5: Standard Operating Procedures.

8 Health and Safety Considerations All employees have received spill clean-up training. All personnel responding to sewage spills MUST be trained in the use of proper personal protective equipment and good hygiene practices. Only employees with proper training will assist in the clean-up of sewage spills.

9 SECTION G: EH&S RESPONSE Immediately following a report of a sewage spill, EH&S shall: 1.

Contact a SAMPLING CONTRACTOR to coordinate initial sampling (see Attachment 3: Water Quality Monitoring Program Plan). b. Post the creek with public health warnings as needed. 5. Fill out Sanitary Sewer Overflow (SSO) Incident Reporting Form.

11 SECTION H: FS / RSSP / BGC PLUMBER RESPONSE Immediately following a report of a sewage spill, FS, RSSP, and BGC shall: 1. Contact EH&S during business hours at (510) or UCPD after hours at (510) UCPD will contact an EH&S after-hours responder. 2. Respond to the site and contain the spill. If possible, plumbers should divert the sewage to an alternate manhole (downstream or another sewer line) by pumping to eliminate the release to the storm drains or turn off the water supply to the discharging building. 3. Correct the plumbing problem. Once the spill is contained, plumbers should correct the problem. If necessary, Roto-Rooter or other contractors should be called for assistance. 4. If there is likelihood for pedestrian traffic to have access to the site, barricade the area. 5. Fill out Sanitary Sewer Overflow (SSO) Incident Reporting Form for signature and submittal to EH&S. The field reporting form should be submitted as soon as possible. 6. Coordinate clean up as needed. SECTION I: SAMPLING See Attachment 3: Water Quality Monitoring Plan for detailed instructions on triggers for water quality monitoring.

12 SECTION J: NOTIFICATION AND REPORTING PROCEDURES Reporting Procedures for the General Public The general public should report sewage spills immediately to either: Department Phone Number Office of Environment, Health & Safety (510) UC Police Department (510) Reporting Procedures for Campus Employees Campus employees should contact their appropriate maintenance department to handle sanitary sewer overflows. Department Phone Number Facilities Services (FS) (510) Residential Student Services Programs (RSSP) (510) Berkeley Global Campus at Richmond Bay (BGC) (510)

13 Reporting Procedures for EH&S Reporting procedures vary depending on what spill category the SSO belongs to. The following table defines the different categories of SSOs: Category Name Category 1 SSO Definitions Discharges of untreated or partially treated wastewater of any volume resulting from an enrollee s sanitary sewer system failure or flow condition that: Reach surface water and/or reach a drainage channel tributary to a surface water; or Reach a Municipal Separate Storm Sewer System (MS4) and are not fully captured and returned to the sanitary sewer system or not otherwise captured and disposed of properly. Any volume of wastewater not recovered from the MS4 is considered to have reached surface water unless the storm drain system discharges to a dedicated storm water or groundwater infiltration basin. Category 2 SSO Discharges of untreated or partially treated wastewater of 1,000 gallons or greater resulting from an enrollee s sanitary sewer system failure or flow condition that do not reach surface water, a drainage channel or a MS4 unless the entire SSO discharged to the storm drain system is fully recovered and disposed of properly. Category 3 SSO Private Lateral Discharges (PLSD) All other discharges of untreated or partially treated wastewater resulting from an enrollee s sanitary sewer system failure or flow condition. This category is not applicable to UC Berkeley since UC Berkeley owns all of its laterals and mains. See Sewer System Management Plan, Figure 2-2 Chain of Communication for SSOs in the each site s respective reporting procedures.

14 SECTION K: PUBLIC HEALTH NOTIFICATIONS Authority to post and remove public health warnings Authority to post and remove postings at UC Berkeley has been assigned to the Director of EH&S. The Director has delegated the posting authority within EH&S when these procedures are followed. In general, all posting is to be performed under the direction of EH&S. Public health warnings can be removed upon the approval of the EH&S Director or delegated EH&S staff member. If the SSO has migrated off UC Berkeley property, public health warning signs must be coordinated with the consultation of the downstream agency, usually the Environmental Health Department (example: for UC Berkeley CS - City of Berkeley s Environmental Health Division would be contacted). Triggers for Posting UC Berkeley Property Barricades and warning signs should be posted whenever a sewage spill is detected or suspected that may pose a public health concern. Public health postings should be placed at visible locations where there is likelihood for the public to have access to the contaminated area (which includes landscaped and paved areas). Public health postings with high traffic (such as Lower Sproul paved areas, etc.) should utilize multiple barricades such as cones in addition to caution tape. Traffic should be redirected inside building structures so occupants do not come in contact with the sewage as clean-up is occurring. Posting is not necessary if a significant rainfall event occurs that adequately flushes the contaminants from the site. Non-UC Berkeley Property In the event that sewage has been discharged off UC Berkeley property, the downstream sewer agency must be contacted to coordinate posting. In general, the downstream sewer collection system agency is responsible for posting, but the agency may request assistance, in which case, UC Berkeley signs can be posted in locations that they recommend.

15 Public Health Warning Statement and Placement Stake Signage (for spills to the creek) Following is the public health warning that may appear on signs posted along Strawberry Creek on the UC Berkeley Central Campus. (Note: BGC and UVA may have similar language that is appropriate for the location.) WARNING RAW SEWAGE IN WATER AVOID CONTACT WITH CREEK WATER This section of Strawberry Creek contains untreated sewage as a result of a sewer line failure. Do not drink or touch the water. Keep children and dogs away from the creek. The campus is currently working on repairing the sewer. For more information, contact the Office of Environment, Health & Safety at (510) These warning signs should be placed in a conspicuous area on both sides of the creek, in general, approximately every 100 feet. If necessary, caution tape should be strung between signs, especially in areas where the chance of incidental contact with the creek is greatest. Other Signage Laminated signage, such as the one below, can be posted in the area where there is sewage spill contamination or where stakes aren t feasible to use. Often times, a barricade and caution tape may be sufficient to warn the public of the hazard if cleanup is underway.

Water quality sampling must be performed for sanitary sewer overflows (SSOs) that are 50,000 gallons or greater and reach surface water. In addition, water quality sampling will be performed for SSOs under 50,000 gallons to assess the impacts to surface water when the spill shows an observable influence (example: odors, discoloration, steam, etc.) and the spill remains on UC Berkeley property for the 48-hour window for sampling after the SSO notification. o For 50,000+ gallons: In the case where the source of the SSO has been stopped and the entire SSO has migrated off UC Berkeley property, sampling must be coordinated with the downstream agency. o Less than 50,000 gallons: If a significant rainfall event (> 0.25 inches in 24 hours) has flushed the creek with storm water adequately to remove all deposited sewage. No water quality monitoring is needed. Safety and Access. Water quality sampling should only be performed if it is safe to do so and access to the surface water is not restricted. Unsafe conditions include, but are not limited to, visibility, heavy wind or rains, slippery and/or steep riverbanks, etc. When sampling is not

27 possible, details of the situation will be recorded in the certified Category 1 SSO Report and the SSO Technical Report (for spills above 50,000 gallons) submitted to the CIWQS Online SSO Database. Who Collects the Sample. EH&S will call a sampling contractor to collect the sample. When to Sample. Sampling must be performed (when and if it is safe to do so) within 48 hours of UC Berkeley becoming aware of the SSO. Where to Sample. Sampling should account for spill travel time in surface water (see Sample Collection Procedure below). Required Water Quality Analyses. Analyze for ammonia, dissolved oxygen, total and fecal coliform, temperature, and ph. The bacterial indicators should be analyzed per the RWQCB Basin Plan (see Sampling Parameters below). Optional Follow-Up Monitoring. It may be appropriate to conduct additional monitoring by sampling and/or visual inspection, depending on the original monitoring results. For example, if an impact from the SSO is observed, follow-up monitoring could be conducted until the water body has reverted to an estimated baseline condition. Follow-up monitoring will also be conducted in communication with the downstream sanitary sewer agencies and the downstream Environmental Health Divisions. Water Quality Sampling Protocol Notification to Contractor Once EH&S is notified of a sewage release to surface water, EH&S will immediately notify one of the contractors below to collect samples.

A contractor may use an equivalent procedure to assess impacts to the creek as long as the minimum number of samples is taken from the stated sampling locations and the required analyses are conducted. Procedures may slightly diverge from this standard procedure if sampling locations are past UC Berkeley property. The contractor is expected to submit their final procedure if it differs from the written procedure below. 1. Obtain appropriate sampling equipment and containers. 2. Determine the point that the SSO entered waterway and photograph this location (include a reference point in the photo). Note: EH&S will provide as much information about this location prior to the contractor s arrival. 3. If sampling is performed after the SSO has stopped, estimate the SSO travel time. This may be done by observing or dropping floatable debris in the surface water and timing how long it takes to travel over a measured distance (e.g., 100 feet). Include sections in the surface water where there are bends, bottlenecks, or other characteristics that may slow down the flow. If the first measurement is uncertain, this time estimate may be performed three to five times, and the values average to determine the estimated travel time. The velocity in the upper portion of the water body can then be calculated by dividing the measured distance by the average time. An alternative way to measure the SSO travel time is to use a velocity probe (such as a Globe Water FP111-S Flow Probe) to determine the rate of flow in the water body.

29 4. Determine the source location for water quality sampling by accounting for SSO travel time. a. If the SSO is occurring, the source location is the point where the SSO is entering the waterway. b. If the SSO has stopped, calculate the approximate downstream distance from the original SSO location by dividing the time since the SSO occurred by the estimated velocity. This is the approximate downstream distance from the SSO discharge point to the source sampling location. i. If this distance is beyond our property, EH&S will coordinate with the downstream sanitary sewer agency for sampling. UCB: Contact City of Berkeley Environmental Health Department at (510) BGC: Contact City of Richmond Municipal Sewer District, Chad Davisson, General Manager at (510) (office) or (510) (cell) UVA: Contact City of Albany Public Works at (510) Due to the possible tidal action in the surface water and other factors, another method may be used to determine the source location at the discretion of the Legally Responsible Official (LRO) or the Director of Environment, Health & Safety. 5. Put on safety gloves and safety glasses. 6. Upstream Sample Collection: Collect the upstream samples first. Move approximately one hundred feet (100 ) upstream of Source location. Label each of the sample bottles marked Upstream A, Upstream B, and Upstream C with the date and time. a. Take a photo of the sample location, including a reference point in the photo. b. Fill the three labelled bottles against the direction of the water flow. Collect samples well away from the bank, preferably at a point where water is visibly flowing. Avoid sampling debris or scrum layer from the surface. c. Use the thermometer to measure the temperature of the Upstream C sample three times and record the results. d. Place each sample in the cooler after collection. Source Sample Collection: Collect the source samples next. Move approximately ten feet (10 ) downstream of the Source location. Label each one of the sample bottles marked Source A, Source B, and Source C with the date and time. a. Take a photo of the sample location, including a reference point in the photo.

30 b. Fill the three labeled bottles against the direction of the water flow. Collect samples well away from the bank, preferably at a point where water is visibly flowing. Avoid sampling debris or scum layer from the surface. c. Use the thermometer to measure the temperature of the Source C sample three times and record the results. d. Place each sample in the cooler after collection. Downstream Sample Collection: Lastly, collect the downstream sample. Move one hundred feet (100 ) downstream of the source location. Label each one of the sample bottles marked Downstream A, Downstream B, and Downstream C with the date and time. a. Take a photo of the sample location, including a reference point in the photo. b. Fill the three labeled bottles against the direction of the water flow. Collect samples well away from the bank, preferably at a point where water is visibly flowing. Avoid sampling debris or scum layer from the surface. c. Use the thermometer to measure the temperature of the Downstream C sample three times and record the results. d. Place each sample in the cooler after collection. 7. Record all sample information. 8. Transport the cooler containing the samples and the completed documentation to a laboratory as soon as possible after the first sample collection. The parameter with the shortest holding time is bacteria at 8 hours (from sample collection to beginning of analysis), but sample analysis should begin as soon as possible after sample collection. Conditions to Stop Monitoring After the analyses have been performed (see Water Quality Analyses Protocols below) and the results have been reviewed and finalized, consult with the appropriate Environmental Health Division (either City of Richmond, City of Berkeley or City of Albany). As soon the appropriate City s Environmental Health Division (depending on where the SSO occur) is satisfied with the results, monitoring for this SSO may stop. If Environmental health Division is not satisfied, the contractor is to repeat the Sample Collection Procedure steps (or equivalent) until the Environmental Health Division deems that it is not a risk to public health.

33 ATTACHMENT 4: LESSONS LEARNED: SEWAGE SPILL RESPONSE In the 1980s, the campus and City of Berkeley response to sewage spills was primarily one of stopping it at the source. Sewage was allowed to drain down the creek and decay over time or be washed away by rains. In the early 1990s, agencies such as the Department of Fish and Game began to require that sewage released to the creek be pumped out of the creek back into sanitary sewers downstream of the blockage. Pumping of the creek is performed by damming the creek with sandbags in a location in proximity to the sanitary sewer and pumping the sewage and creek water into the sanitary sewer. Pumping continues until the sewage leak is repaired and most of the sewage pumped from the creek. While normal dry weather flows are low enough to allow pumping the creek using pumper trucks or portable gas powered trash pumps, contractor response time was historically poor. It would often take 4 to 6 hours for contractors to arrive with trucks and set up before pumping began, and by that time a significant portion of sewage flowed out of campus and into the City and the Bay. Because of the slow response time, in 1999 EH&S purchased three Multiquip 3 x 3 centrifugal pumps with 5.0 H.P. Honda GX-140 engines (77 lbs. dry weight) and a quick cleaning capacity for sewage response. With two engines stored in a secure centrally located room allowing for quick access to the creek and one kept on a Facilities Services truck, response time between sewage spill discover and creek pumping has been shortened from many hours to 30 minutes to an hour. SEWAGE SPILL RESPONSE PUMPING CALCULATIONS The Multiquip centrifugal pumps have a maximum capacity of 16,000 gallons per hour (GPH, ~260 GPM), maximum lift of 25 ft and maximum head of 105 ft. In general, the pumps are expected to operate at less than maximum capacity, in part due to the need to lift the water from creek pools feet to the sanitary sewer. Assuming 200 GPM operating conditions, all three pumps would be required to divert flow from the central campus sanitary sewer draining to side sewer #1 (SS#1, MH#384) when that sewer is running at maximum capacity of around 500 GPM and the North Fork is contributing typical dry weather flow of around GPM. [Daily sewer discharge from campus is 785,000 (Source: 2002 EBMUD UC Berkeley Wastewater Discharge Permit.). Assume 75% drains to SS#1 and 25% to other side sewers. SS#1 daily average flow is = 400 GPM with diurnal fluctuations and peak flows in the early afternoon (assume 500 GPM maximum). North Fork dry weather flow = GPM. South Fork dry weather flow = GPM. (Quick conversion CFS x = GPM)]. This would be a worst-case scenario. However, usually two centrifugal pumps are needed, and in some cases these have been supplemented by use of plumber s sump pumps, which are especially useful in providing a pump around to divert clean upstream water around the impacted area.

34 ATTACHMENT 5: STANDARD OPERATING PROCEDURES (SOPs) Creek Pumping Procedure Scenario: Sewage overflow has entered surface water such as Strawberry Creek. Procedure is applicable in both dry weather and wet weather circumstances. Method A: Divert creek water around the spill Applicability: If response time is quick enough to capture the leading edge of spill. Otherwise, go to Method B. Method B: Divert creek water AND sewage Applicability: In cases where you cannot capture the leading edge of a spill. Equipment Needed: Trash Pump Sandbags (for dam structure) Equipment Needed: Trash Pump Sandbags (for dam structure) Notifications Needed: EBMUD approval needed prior to pumping creek water into the sanitary sewer (510) Procedure: 1. Place a dam immediately downstream of the sewage spill. Using a trash pump, begin pumping the sewage to an adjacent sanitary sewer, downstream of the failure. 2. Place a dam immediately upstream of the affected area and, using another trash pump, pump creek water to below the dam placed in Step 1. Notifications Needed: EBMUD approval needed prior to pumping creek water into the sanitary sewer (510) Procedure: 1. Place a downstream dam. 2. Use a trash pump to pump the contaminated water to the sanitary sewer. (Pumping should continue until clean water is flowing.) 3. If a layer of solids has been deposited on the creek bed, it will need to be flushed with dechlorinated water. All wash water should be pumped to the sanitary sewer.
