Carpinteria Sanitary District January 21, 2014 Page 1 General Manager’s Status Report – General Manager reported on the following: Rincon Point Septic to Sewer Project Update – General Manager said directional drilling of the 4-inch diameter force main in the US 101 corridor has been completed. There were a number of small frac-outs during the installation process, but they were fully contained with no impacts to water quality. The incidents were reported to the appropriate agencies. Construction of the retaining walls at the pump station site is complete. The archaeological work has commenced inside the community. An archaeological orientation meeting was held at the District office on January 9th. Travis Ag started potholing within the community the week of January 9th. Dudek began the Phase 3 excavation units the week of January 9th. SAMA Meeting Report – General Manager said he attended the monthly meeting of the Sanitation Agency Managers’ Association at the El Estero Wastewater Treatment Plant in Santa Barbara on January 8th. A presentation on the Los Osos community sewer project was given by Steve Mimiaga. Collection System Rehabilitation Project – General Manager said the Sancon project team was onsite for a pre-construction meeting on January 13th. Cleaning started in the Padaro Lane Area. The City of Carpinteria asked that the District procure a separate encroachment permit in lieu of performing this work under the District’s blanket permit. Sancon provided insurance certs to the City for the separate permit. District staff is managing this project and most of the required submittals have been received and approved. Eddie Saenz attended a two-day specialty training seminar on CIPP construction inspection, offered by NASSCO. Eddie will provide full time inspection during the course of this work. His extensive experience will be beneficial. West Padaro Main Sewer Extension Project – General Manager said the boundary reorganization for this project was unanimously approved by Santa Barbara LAFCO at a special meeting held on January 9th. There is a 30-day reconsideration period before the annexation is finalized and recorded, but CalProp is working with the county Planning and Development staff to get the land use permits finalized so that construction can move forward. Lance Lawhon will provide inspection for the District during the construction phase. Santa Claus Lane US 101 Crossing – General Manager said collections staff successfully cored a hole through the manhole and concrete plug into the casing on either side of the crossing. Water flowed out of the hole from the downhill side and continues to flow indicating a breach in the casing at some location. However, once the water drained out, the PVC carrier pipe seems to have settled back into a position closer to the design grade. Wastewater is flowing now unrestricted. Additional investigation will continue to determine the appropriate remedial action. CASA Winter Conference – General Manager said he attended the CASA Winter Conference in Indian Wells, January 15th to 17th. During the CSRMA workshop, held Wednesday afternoon, our District was a recipient of the Workers’ Compensation Award for having no claims during the 2013 calendar year. The keynote speaker was George Hawkins, Executive Director of DC Water. Operations Update – General Manager said the treatment plant is operating well and in full compliance with our NPDES discharge permit. Staff is dealing with some foaming in the aerobic digester. This is unsightly and a nuisance but doesn’t pose any problems for plant operation or compliance status. Today the District received a couple of calls from residents throughout the Carpinteria area regarding an odor. General Manager said that there weren’t any odors emanating from the plant. Atmospheric and or oceanic conditions may be contributors to the odors that area residents have been smelling. The collection system is functioning well with no problems to report. A minor lower lateral SSO occurred on January 8th at a residence on Arbol Verde Drive. The lateral was already on a maintenance schedule and this event will prompt replacement or repair of the lower lateral to prevent recurrence. General Manager presented a slide show of pictures taken at the Rincon Point Septic to Sewer project site.

Carpinteria Sanitary District January 21, 2014 Page 2 Amendment No. 3 to Cash Contract No. 395 – Carollo Engineers – Aerobic Digester Replacement Project Design – General Manager said on March 20, 2012 the District approved Cash Contract No. 395, engaging Carollo Engineers to provide preliminary and final design services for the District’s aerobic digester replacement project. The agreement authorized a fee of $347,203, based on a comprehensive scope of services developed in coordination with District staff. In October 2012, an amendment to the agreement was approved by the Board and a second amendment was approved by the Board at its October 1, 2013 meeting bringing the current authorized design fee to $544,266. General Manager said the final design phase has been completed and the project is out to bid, with a schedule bid opening date of February 19, 2014. The District recently entered into an agreement with MNS Engineers for the provision of construction management and inspection services during the bidding and construction phases of the project. The services of the design engineer will also be required during this period. General Manager said Carollo, as the designer of record, will review certain submittals, address complex questions, RFI’s, and prepare design addenda or change order directives as necessary. General Manager said Carollo has prepared a proposed scope of services for construction period engineering support. This proposal was included in the packet for Board review. A total fee amendment of $184,131 is proposed. If approved, the revised contract amount would be $728,397. General Manager said if authorized, a letter would be sent to Carollo to effect the amendment. A copy of the letter was distributed for review. General Manager said it was staff’s recommendation that the Board approve Amendment No. 3 to Cash Contract No. 395 between the District and Carollo Engineers, increasing the authorized design fee by $184,131 making the total $728,397. Director Damron made a motion to approve Amendment No. 3 to Cash Contract No. 395 between the Carpinteria Sanitary District and Carollo Engineers as presented. Director Velasco seconded the motion and the motion was approved by a 5-0 vote. The Clerk noted for the record that the vote was unanimous.

General Manager’s Status Report

TO: Board of Directors

FROM: Craig Murray, P.E. - General Manager

SUBJECT: General Manager’s Status Report

DATE: February 18, 2014

Employee Recognition. In January we held a quarterly all staff meeting and Joey Mendoza was recognized as the Employee of the Quarter for the 4th quarter of 2013, based on the recommendation of the independent selection committee. Joey was recognized for his willingness to help his coworkers at every turn and for the positive attitude he brings to the workplace each day. Congratulations Joey!

Rincon Point Septic to Sewer Project Update. Good progress has been made on both components of this project. Tierra has reached the 80% completion level on their project and report that they are still on target to finish the work in March. The entire pipeline above the pump station is complete and has been pressure tested. Foundations and flat work concrete at the pump station site are complete and work is beginning on the control/generator building. Replacement of the damaged ATT/Verizon fiber optic conduit was completed on February 13th. SCE is working to set a new power pole and make system improvements to deliver 480V three phase power to the lift station site. Good cooperation from the County Parks Department and the general public continues.

Travis Ag is proceeding well on mainline installation. The line from the community up to the pump station was successfully installed. One small frac-out occurred within the County parking lot, but it was fully contained with no potential impacts to surface waters. This incident was reported to applicable agencies as required by our permits. The mainlines in the Santa Barbara County side of the community are complete, with no frac-outs reported in this area. Travis Ag has done an excellent job thus far communicating with residents and maintaining a clean and organized job site. The vacuum potholing of existing utilities has worked very well to minimize impacts. Dudek’s team of archaeologists and monitors are nearly finished with the Phase 3 Cultural Resources investigation. Two one-meter units were completed on the Santa Barbara side and 15 of 19 units have been completed on the Ventura side.

The design and project management team has been working with many homeowners to finalize outstanding issues in preparation for the work on private properties. Several homeowners have indicated their intent to relocate the grinder pump tanks and we are coordinating with the project archaeologist to ensure that all mitigation measures and permit conditions are adequately complied with.

On February 6th I gave a tour of the project site to Steve Moore, a member of the State Water Resources Control Board. Mr. Moore was accompanied by Kelley List, our grant manager from the SWRCB Division of Financial Assistance.

1 Collection System Rehabilitation Project Update. National Plant Services, a subcontractor to Sancon, has been working on pipeline cleaning activities throughout our service area in advance of the CIPP rehabilitation process. This work has progressed slowly due to the nature of the mineral deposits and scale in the clay lines. There have been some minor reported issues with respect to traffic control and surging toilets. A progress meeting with Sancon and their subcontractors was held on February 13th. Sancon will mobilize their forces on February 18th to begin the lining process and to provide oversight of their subcontractor. The District authorized emergency replacement of a 100-foot length of pipe at the end of Anita Street. Following the cleaning activities, it was apparent that this pipe had structurally failed and collapse was imminent. Work was completed by Tierra Contracting, also a subcontractor to Sancon, on a force account basis.

Aerobic Digester Replacement Project Update. As of the date this report was prepared, we remain on target to open bids on Wednesday February 19th at 2:00 p.m. The mandatory pre-bid job walk was held on January 29th and there were 10 general engineering contractors represented at the meeting. The project team has fielded a significant number of questions from prospective bidders. Addendum No. 1 was issued on February 11th. A second addendum is anticipated before the bid date. The City of Carpinteria Planning Commission approved the Development Permit Revision and Coastal Development Permit for the project on February 3rd. The commissioners were very supportive of the project. Two ten day appeal periods run sequentially before the permit becomes final, but the conditions of approval were added to the Contract Documents by addendum.

Quarterly Utilities Committee Meeting. A joint committee meeting will be held with members of the Carpinteria Valley Water District Board and Carpinteria City Council Members on February 27th at the Water District. A copy of the draft agenda is attached.

SBSDA Meeting Report. I attended the January 27th meeting of the Santa Barbara chapter of CSDA in Buellton. This was the annual organizational meeting and Board members for the current year were elected. The LAFCO Special District Selection Committee met just prior to the chapter meeting and Director Moorhouse was elected for another 4-year term as LAFCO Commissioner representing special districts. Congratulations!

Operations Update: WWTP and Collection System operations updates are as follows: • The treatment plant is operating in full compliance with our NPDES discharge permit. • The collection system is functioning well with no reported mainline blockages or SSOs during the period. • District staff is working with the Lucity development team on the new computerized maintenance management system. Data transfer has happened and remote server and client software installation is underway. The Lucity team will mobilize later this month to initiate the on-site portion of the work. • The District’s 1997 VacCon combination sewer cleaning machine was sold by Ken Porter Auctions at a February 1st public auction for $34,000. • The District’s IT consultant made some critical improvements to our server and network on February 7th. Concurrently, we engaged them to perform a District-wide network/workstation assessment and provide recommendations for future planning purposes. • Mark Bennett attended a multi-day training session in Ontario, California as preparation for the Grade V Operator Certification exam offered by the SWRCB which he will take in April.

3 Carpinteria Sanitary District Board of Directors Meeting

STAFF REPORT

TO: Board of Directors

FROM: Craig Murray, P.E. - General Manager

SUBJECT: Change Order No. 1 to Cash Contract No. 404 Rincon Point Offsite Improvements Project

DATE: February 18, 2014

REQUESTED ACTION: Board Consideration and Approval of Change Order No. 1 to Cash Contract No. 404 with Tierra Contracting, Inc.

FUNDING SOURCE: Assessment District 2007-1

BACKGROUND: On August 17, 2013 the Board of Directors approved Cash Contract No.404 between the District and Tierra Contracting, Inc. (Tierra). The currently authorized contract price is $1,459,771.00 with a 140 working day construction period ending on March 14, 2014.

Tierra has completed approximately 75% of the contract work on the Rincon Point Offsite Improvements Project, with site work at the pump station site the only remaining major component of work. Thus far the project has proceeded very well, with no major complications.

A number of project changes have been necessary during the construction phase to date. Some of the changes were at the direction of the District and/or Penfield & Smith, in coordination with Tierra, to achieve an improved project outcome. One change to piping affixed to the US101 bridge was directed by Caltrans. Six discrete changes were addressed through bulletins (proposed change order requests) issued to Tierra. Work progressed and the construction manager documented site conditions and reviewed daily extra work tickets.

Change Order No. 1 to Cash Contract No. 404 was drafted to appropriately update the contract terms. This change order, including the attachments, documents all of the extra work for the project directed by Bulletin Nos. 1 through 6. Based on staff review, the costs are reasonable and the work was necessary to successfully complete the work. If approved, Change Order No. 1 would increase the contract price by $19,778, making the revised total $1,479,549. No change in contract time is proposed for Change Order No. 1.

RECOMMENDATION: Staff recommends that the Board approve Change Order No. 1 to Cash Contract No. 404 with Tierra Contracting, Inc. as presented.

SUGGESTED MOTION: I move that the Board approve Change Order No. 1 to Cash Contract No. 404 with Tierra Contracting, Inc. as presented.

34 SECTION 1 – OPERATIONS SUMMARY

WASTEWATER TREATMENT PLANT

Treatment Plant Operations For the calendar year 2013, the average effluent Biochemical Oxygen Demand (BOD) discharged by the Carpinteria Sanitary District (CSD or District) WWTP was 4.08 mg/L. The average annual BOD removal efficiency was 98%. The average effluent Total Suspended Solids (TSS) concentration was 3 mg/L. The annual TSS removal efficiency was 98%. The District’s Facilities Maintenance Manuals and Contingency Plan were reviewed in 2013 and were found to be complete and current for the CSD WWTP during the reporting period. The District Arc Flash program is continually updated to be compliant with NFPA 70E requirements. Revisions to facility electrical drawings are made, equipment labeling is updated as necessary and critical training of personnel is performed.

Treatment Plant Improvements

The District continually inspects and maintains the equipment at the wastewater treatment facility. A number of facility improvements were undertaken in 2013.

Maintenance O&M Digitized. In 2013 the District started digitizing the current operations and maintenance manuals. The manuals are stored on a cloud based storage program that allows the operators access to the files via a tablet computer (Ipad) anywhere on site or where there is web access. A secure wireless network was also added throughout the plant site. Along with the O & M manuals, daily plant inspection are now performed using tablet computers that time stamp inspections for each piece of equipment as well as digitally signing and archiving the inspections.

Energy Efficiency Project. The District completed the replacement of two air compressors within the treatment plant. District staff installed the compressors in January 2013. Rebates from Southern California Edison partially funded the project. The additional energy savings will pay for the remainder of the cost over three years.

Digester Replacement Engineering Design. The District engaged Carollo Engineers to design new aerobic digesters to replace two existing digester tanks, originally constructed in the 1950’s as anaerobic digesters and converted to aerobic operation in the 1990’s. This major capital improvement project will include new rectangular concrete tanks, hybrid positive displacement blowers, fine bubble diffusers and new feed pumps to the dewatering system. Concurrently, the District will replace its disinfection system and chemical storage tanks and relocate this unit process to an area adjacent to the existing chlorine contact tank. The design and specifications were completed and will go out to bid in January 2014. Construction is scheduled to commence during the second quarter 2014.

WASTEWATER COLLECTION SYSTEM

Collection System Operations

In order to keep the entire collection system clean and to prevent maintenance-related spills and blockages, the District implements two pipeline cleaning programs:

• System-Wide Cleaning Program (98,454’ cleaned in 2013). This program is designed to ensure that every pipe in the collection system is cleaned at least once within a 3-year period. The projected end of cleaning cycle is April of 2014.

• Priority Line Cleaning Program (58,083’ cleaned in 2013). This program is used for pipes that require more frequent cleaning due to more frequent accumulation of material within the pipe.

Additional Collection System Activities: • Response to USA/ Dig Alert Requests The District’s Collection System Department also marks the location of mainline sewers in response to USA Dig Alert notifications that come into the office via email on a daily basis. This important function is necessary to protect the integrity of our buried infrastructure from damage associated with other excavation and subsurface work. • Manhole Inspections Collection System personnel routinely perform inspections of manholes concurrent with hydro cleaning and/or CCTV inspection activities. Manhole condition is documented on a MACP form. Certain manhole repairs, such as concrete collar replacement, are done using in-house resources. • E-One Grinder Tank/Pump Inspections In 2012, the District commenced maintenance and inspection duties for 63 E-One grinder pump units located in the Sandyland Cove and Sandpoint Road communities. These systems consist of a holding tank, a grinder pump and a control panel equipped with an automated audio/visual alarm. In 2013, the Collections Department implemented a yearly inspection cycle to ensure that the homeowner is following proper usage protocols and that the pump/control panel is in good working order. • Smart Cover Inspection/Monitoring The District currently has seven (7), “Smart Covers” strategically located within the collection system to alert District personnel via email and text message if a surcharge condition arises. Although these units are automated, the Collections System Personnel routinely inspect the units’ condition and configuration to ensure they are in proper working order and orientation. Two of the seven units were added to the District’s inventory in 2013. • CCTV Lateral Pipeline Inspection In January of 2013, the Collections System Department launched a Sewer Lateral Inspection/Inventory Project. The goal of this project is to ensure that the District is servicing all of its assets by updating the lower lateral inventory database. This project requires the

36 Field Crew to go to each household within the District, determine if a property line cleanout exists and if found, inspect, clean and catalog the asset. Video inspections of the laterals are being accomplished with a portable “push” camera system that wirelessly sends a video signal to the CCTV inspection van for processing by NASSCO-PACP certified District personnel. If problems are found, such as root intrusion or grease buildup, the line is cleaned by either the Gorlitz sewer cleaning machine (snake) or the lateral hydro cleaning kit mounted on the Vactor combination truck.

• Spill Response Readiness

Sanitary sewer overflow (SSO) calls are considered to be a high priority that demands a prompt response to the location of the reported problem. The District’s goal is to respond to an SSO report within 15 minutes during normal working hours and within 30 minutes for after hour’s calls when possible. The Collections Department maintains spill response readiness during normal and after hours as outline in the District SSO Response Plan.

Collection System Improvements

CCTV Mainline Inspection Project- (2010-2013) As of October of 2013, the Collections Department completed a comprehensive system-wide collection system CCTV inspection program. The project allowed the District to collect inspection data using the NASSCO PACP defect coding system. Upon completion, the District prioritized a rehabilitation schedule for use in preparing a construction bid package for the 2013/2014 Collection System Rehabilitation Project.

Point Repair Projects (May 2013) Upon finishing the CCTV Mainline Inspection Project, the Collections Department identified and prioritized a number of point repairs to be done in low ground water conditions. The point repairs were as follows: • 126 Ash- Cleanout Repair • Cedar Place- Mainline repair (6G400-7G005) • Third St.- Mainline repair (7G155-7G230) • Old Linden- Mainline repair (6H105-6G095) • Linden-Mainline repair (5H090-5H165) • Manhole Rehabilitation/ Smart Cover Installation (8G010) • Manhole Rehabilitation/ Smart Cover Installation (3B045)

Collection System Rehabilitation Project – (2013-2014) The District is beginning a major collection system rehabilitation project. In house staff has completed planning and design of a project that involves rehabilitation or replacement of over 16,000 linear feet of gravity sewer. A construction contract was issued to Sancon Engineering in November 2013 and preliminary construction activities commenced shortly thereafter. The

37 work involves primarily cured in place pipe (CIPP) lining of sewers ranging from 6-inch to 10- inch diameter. The work also includes a number of point repairs and top hat installations to address identified defects. Combination Sewer Cleaning Truck Procurement (September 2013) The replacement of a 1996 model year Vac-Con combination sewer cleaning machine with a 2013 Vactor 2100 Plus was completed in September of 2013. The new vehicle has been a key element in accelerating our System Wide Cleaning Project and has proven to be more powerful, efficient and safe for District personnel. Addition of Collections Department Personnel (September 2013) Upon completion of a manpower report based on current and projected workloads, the District elected to create a new Collections Operator I position within the organizational structure. As of September 2013, this full-time position was filled and the Collections Department has experienced a more consistent manpower resource allocation and workflow, the ability to engage multiple cleaning tasks simultaneously, and a steady increase in productivity. Update of Computerized Maintenance Management System (2013-2014)

This project involves migration from the District’s current computerized maintenance management system (CMMS) software platform to a new application, particularly for collection system management and data integration. There are a myriad of options out there but after careful consideration research, management and staff has identified “Lucity” as the desired software solution. A contract for software procurement and application development/integration was issued to Lucity in December 2013. This project is scheduled to begin in January of 2014.

Lift Station Improvements The District routinely inspects and maintains each of its seven lift stations. Pumps and equipment are regularly serviced and maintained. Emergency systems (backup generators, pumps, etc.) are regularly tested and serviced. In 2013, the District replaced the controller at Lift Station No. 5. One of the dry-pit submersible pumps at Lift Station No. 1 was rebuilt by District staff at the manufacturer’s repair facility under supervision as a training exercise. Staff now has the capability to overhaul the pumps in house.

Grease Control Program District staff has continued to implement a Fats, Oils and Grease (FOG) Program within its service area. Grease interceptor maintenance requirements have been enforced throughout the reporting period and pipelines prone to grease accumulation have been added to the District’s priority mainline inventory, where appropriate. Routine facility inspections were made during the 2013 calendar year with an emphasis on permit renewals. We have continued to ramp up FOG Program activities and have performed outreach to residents and business members within the District’s service area.

38 Source Control Program

The District maintains a limited Source Control Program. One permitted user, Kilovac (Tyco Electronics), is regularly inspected and monitored. This facility is scheduled to close its manufacturing process by the end of 2013 and will no longer be discharging non-domestic wastewater to the District’s collection system. An annual business survey was performed in 2013 to identify new or changed businesses within the District’s service area. During this process, facilities with the potential to discharge industrial wastewater are surveyed for the purpose of determining pretreatment and permitting requirements.

Sewer System Overflows The District reports individual SSOs to the RWQCB and other responsible agencies when they occur. Response to SSOs follows the protocols established in the District’s Sanitary Sewer Overflow Response Plan. The District reported one (1) mainline SSO during the 2013 calendar year. A spill of approximately 140 gallons occurred on July 28, 2013 at 3194 Via Real (SSO Event ID 797918). This SSO was caused by a combination of grease accumulation and possibly a foreign object in an 8-inch diameter VCP gravity sewer mainline. District staff responded to mitigate the impacts from this overflow and cleaned up the impacted site in accordance with the District’s SSO response plan. The SSO did not reach waters of the State or any storm drain system. The District reported two (2) SSOs resulting from blockages in the lower laterals serving individual homes. Unlike most agencies in this region, the District owns and has responsibility for the lower laterals (between the property line and the main sewer) within its service area. During 2013, the following SSOs were reported: • Event ID 794590, 5/24/13 – 2 gallon SSO at 5658 Fiesta Drive due to root blockage. • Event ID 800724, 11/10/13 – 14 gallon SSO at 4851 Ninth Street due to root blockage. None of these lateral sewer SSOs resulted in discharges to waters of the State or threats to public health or the environment. All were thoroughly cleaned up by District staff in accordance with our SSO response plan. In response to a slight increase in lower lateral SSO frequency in 2012, the District initiated an effort to develop a more complete lateral sewer inventory and to perform condition assessment using CCTV inspection. We expect this to be a multi-year effort, but it will provide for a more pro-active approach to lower lateral maintenance. Historically, root intrusion into lateral sewer is more prolific during extended periods of drought. The District continues to comply with State Water Resources Control Board Statewide General WDR program for Sanitary Sewer Systems. We have established protocols to comply with the spill reporting requirements set forth in the General WDRs and have performed on-line spill reporting since May of 2007.

EFFLUENT VIOLATION SUMMARY

The District has notified the RWQCB of all effluent limit violations and other permit violations during the reporting period. Notification has been provided verbally over the telephone and confirmed in writing, either by facsimile or in monthly reports submitted to CRWQCB. Attached herewith are copies of the violation notices submitted during 2013.

Re: Chlorine Residual Instantaneous Maximum Effluent Limit Excursion Due to Temporary Loss of Dechlorination Chemical Feed (NPDES CA0047364)

On January 3, 2013 at 8:34 a.m. the dechlorination system at the Carpinteria Sanitary District’s wastewater treatment facility malfunctioned. District operations staff collected an effluent grab sample that was analyzed and found to contain a total chlorine residual concentration of 10,400 ug/L. This represents a violation of the instantaneous maximum effluent limitation of 5,600 ug/L. Dechlorination was restored to full operability at 8:45 a.m. and a confirming sample was collected and found to contain 300 ug/L total chlorine. Mr. Peter Von Langen of the Central Coast RWQCB was notified by phone of this incident.

On January 7, 2013 at 7:25 a.m. the dechlorination system at the Carpinteria Sanitary District’s wastewater treatment facility malfunctioned. District operations staff collected an effluent grab sample that was analyzed and found to contain a total chlorine residual concentration of 7,800 ug/L. This represents a violation of the instantaneous maximum effluent limitation of 5,600 ug/L. Dechlorination was restored to full operability at 8:45 a.m. and a confirming sample was collected and found to contain 900 ug/L total chlorine. Mr. Peter Von Langen of the Central Coast RWQCB was notified by phone of this incident.

The cause of the malfunctions is believed to be chemical crystallization within sodium bisulfite distributing piping due to abnormally cold temperatures. The District utilizes a heated and insulated storage tank for bulk storage of sodium bisulfite, together with insulated distribution piping. However the extreme low temperatures during overnight hours caused the line to plug with crystalized chemical and prevented delivery to the injection point for a short period of time. This was an ongoing problem for a two week period with below normal temperatures for this coastal area. District staff used temporary piping as well as installing a new pipe heater and insulating blankets in an effort to prevent additional freezing issues. The District’s continuous monitoring systems indicated several minor alarm conditions during this period that were not confirmed as violations of NPDES permit limitations.

Coincidentally, there have been no recurring chemical feed problems since receipt of a new bulk delivery of sodium bisulfite on January 7, 2013. The District contacted the chemical supplier and inquired about the potential that the prior batch of chemical was out of specification or could for some other reason have an abnormally high freezing/crystallization point. The vendor has not yet responded.

The District immediately notified the Central Coast RWQCB of both events and left telephone messages for Peter Von Langen. Peter Von Langen called back and directed the District to provide a summary statement with the monthly report for January 2013.

Yours very truly,

45 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013

Executive Summary

The Carpinteria Sanitary Districts discharges up to 2.5 million gallons per day (MGD) of secondary treated effluent into the Pacific Ocean at a depth of 7 m through a 1000 ft outfall pipe. The five benthic sampling stations specified in the NPDES permit are spread along the 7 meter depth contour to the east and west of the outfall. In adherence with the Carpinteria Sanitary Districts NPDES Permit (No CA0047364) Aquatic Bioassay and Consulting Laboratory scientists conducted the receiving water monitoring program on August 8th, 2013. The survey included ship based collections of sediment samples for physical, chemical and biological analyses of the benthic environment, and a visual survey of the outfall pipe and diffuser.

The sediment monitoring portion of this survey was designed to determine if the composition of the sediments and biological communities in the vicinity of the District’s ocean outfall were impacted by the effluent discharge emanating from the outfall pipe. To address this question, the concentrations of chemicals and composition of the benthic infauna community were investigated for outfall associated patterns. In addition, these data were compared to data collected during regional monitoring surveys conducted by the Southern California Bight Regional Monitoring Program and SCCWRP in 2008. Finally, the sediment concentrations of each chemical were compared against NOAA Status and Trends ER-L and ER-M reference thresholds. An outfall inspection was conducted by divers using handheld video equipment to determine if the outfall structure was in serviceable and safe condition. Key findings of the survey include:  Bottom sediments were composed almost entirely of sand (100%) at each of the five sites in the survey area.  Concentrations of sediment total and fecal coliforms were at or near the method detection limits in all cases.  There were no clear spatial patterns in the concentrations of undifferentiated organics (TKN, TOC, BOD and sulfides) in the Carpinteria survey area. The concentrations of each constituent were low and were similar across sites. TOC concentrations measured in Carpinteria sediments were below concentrations measured at similar depths during southern California reference site surveys.  Of the eleven metals measured for this survey, all were above detection at each of the sites, except for silver which was below detection. There were no outfall related spatial patterns in metal concentrations in the survey area. Of the eleven metals, chromium and nickel were slightly greater than concentrations measured during the SCBRMP (2008). None of the metal concentrations measured in the Carpinteria survey area exceeded the ER-L and ER-M threshold values.  The benthic infauna community in the vicinity of the Carpinteria outfall was composed of a rich assemblage of polychaete worms, crustaceans and mollusks during the 2013 survey. A total of 6,665 individuals, consisting of 208 species were collected at the five stations. None of the biological metrics were significantly correlated (p < 0.05) with distance from the outfall, indicating there was no outfall related spatial contaminant pattern. Infauna abundances and numbers of species were statistically lower by ANOVA at R2E, located nearest the outfall terminus. However, the Benthic Response Index (BRI) was significantly least at station R2E which means there was no net loss of reference species and indicating the healthiest infauna community of the five sites.

2

46 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013

 Cluster analysis supported these findings and showed that outfall site R2E was most dissimilar to sites further away from the outfall. These results indicate that there may be an outfall related effect on the benthic infauna in the Carpinteria survey area. However the BRI scores at each site (including the outfall sites) were far below the reference threshold indicating that the infauna populations in the Carpinteria survey area were similar to those found at references sites throughout the southern California Bight.

Abundances, numbers of species, diversity, evenness and dominance measured during the 2008 Carpinteria survey were compared against the same metrics measured on the mainland shelf during the 2008 SCBRMP (Ranasinghe et al., 2011). Abundances and evenness found in the Carpinteria survey area were similar to those found during the Reference site survey. Diversity, numbers of taxa and dominance were somewhat less than what was found during the reference site surveys.

 The visual survey of the outfall found that the end plate of the outfall terminus was secure and the eight inch diffuser port at its center was flowing freely. Inspection of all the lateral diffuser ports on both the east and west sides of the diffuser showed that considerable attached biological growth surrounded each port. Divers cleared two partially obstructed ports on the west flank of the outfall pipe. All standup diffuser ports are now open and flowing freely. No evidence of leaks, damage, erosion, holes, or cracks were observed on any part of the diffuser.

49 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013

Introduction On August 8th 2013, Aquatic Bioassay and Consulting Laboratory scientists conducted the receiving water monitoring program for the Carpinteria Sanitary District in adherence with the City’s NPDES permit No. CA0047364. The survey was conducted at five offshore stations located in the vicinity of the Carpinteria Sanitary District’s Wastewater Treatment Plant outfall. The survey included ship based collections of sediment samples for physical, chemical and biological analyses of the benthic environment and a visual dive survey of the outfall pipe and diffuser. The sediment monitoring portion of this survey was designed to determine if the composition of the sediments and biological communities in the vicinity of the District’s ocean outfall were impacted by the effluent discharge emanating from the outfall pipe. To address this question, the concentrations of chemicals and composition of the benthic infauna community were investigated for outfall associated patterns. In addition, these data were compared to data collected in 2008 and to regional monitoring surveys conducted by the Southern California Bight Regional Monitoring Program in 2008. The outfall inspection portion of the survey was conducted to determine if the outfall structure was in serviceable and safe condition. This survey was conducted by divers using handheld video equipment. This report is divided into a methods section, providing details of the sampling, analysis and reporting procedures; a results section, providing the results in tabular, graphical and text formats; and, a summary and conclusions section. References, team experience and raw data for each phase of the program are included in the appendices.

Benthic Sediment Sampling

Benthic grab sampling was conducted in accordance with Techniques for Sampling and Analyzing the Marine Macrobenthos, EPA 600/3-78-030 (Swartz, 1978); Quality Assurance and Quality Control (QA/QC) for 301 (h) Monitoring Programs: Guidance on Field and Laboratory Methods, (Tetra Tech, 1978); and, The Southern California Bight Regional Monitoring Program Field Operations Manual (SCCWRP 2008).

Sampling was conducted at the five stations from the vessel Hey Jude. After stations were occupied using DGPS, sediment samples were collected using a chain-rigged, tenth square- meter van veen grab. At each station, the grab was lowered through the water column until it was near the bottom and then slowly lowered until contact was made. The grab was then slowly raised until clear of the bottom. Once on board, the grab was drained and initial qualitative observations of color, odor, consistency, etc. were recorded. In addition, visual observations were made of weather, sea state, wind and currents at each site.

Five replicate grab samples were collected at each station for infauna which were sieved through one-millimeter screens and the remaining organisms and larger particles were washed into plastic containers, covered with magnesium sulfate for one half hour to relax the animals and then preserved with 10% buffered formalin (SCCWRP 2008). Chains of

8

52 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013 custody were filled out as samples were collected. The infauna samples were delivered to the Aquatic Bioassay and Consulting Laboratories in Ventura, CA.

Single samples were collected for chemistry from the top two centimeters of the grab sample using a Teflon-coated spatula and placed in pre-cleaned glass bottles with Teflon- lined caps. Grain size samples were collected using the same technique and were placed in zip lock bags. During all collections, the sides of the grab were avoided. Samples were immediately placed on ice and returned to the laboratory.

Laboratory Analyses

Infauna was sorted by Aquatic Bioassay laboratory technicians and biologists into five groups: mollusks, echinoderms, annelids, arthropods, and miscellaneous phyla, following (SCCWRP 2008). Sorting QC involved at least a ten percent check of each sample by a second biologist for infauna not found initially. All samples passed the 95% sorting efficiency standard. After being sorted, annelids, arthropods, and miscellaneous phyla were sent to taxonomic specialist Tony Phillips. Aquatic Bioassay maintains and updates a standardized voucher collection, and all taxonomists are active member of the Southern California Association of Marine Invertebrate Taxonomists (SCAMIT).

Chemical analyses were performed by PHYSIS Environmental Laboratories, Inc. located in Anaheim, CA. A list of chemical constituents, methods and detection limits is provided in Appendix D. Sediment particle size was analyzed by laser diffraction using a Horiba LA-920, laser scattering particle size distribution analyzer by Standard Methods 2560-D. All laboratory duplicates, blanks and matrix spikes were within the data quality objectives for the program.

Data Reduction

Data were entered into Microsoft Access. All results were double checked in accordance with Aquatic Bioassay quality control standards. The following infauna community indices were calculated: Shannon Diversity (H'), species evenness (J), species dominance and Benthic Response Index (BRI). Additionally, infauna station and species groups were identified using cluster analysis. A brief description of each of these indices is presented below.

Numbers of Species. The total number of species present in a sample.

Abundance. The total number of individuals present in a sample.

Shannon Diversity. The Shannon Diversity Index (H') (Shannon and Weaver 1963) is defined as: s H' = -∑ {(nj/N) Ln(nj/N)} where: nj = number of individuals of the jth species N = total indiv. of all species in the sample s = number of species in the sample.

Simpson's Diversity. Simpson’s Diversity takes into account the number of species present, as well as the abundance of each species.

9

53 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013

D = ∑ (n / N)2

Margalef’s Species Richness (D). - Margalef's species richness is a measure of the number of species present, making some allowance for the number of individuals.

D = (S-1)/Log(N)

Pielous Richness (J). The Pielou Evenness Index (J) (Pielou, 1966) is:

J = H' / Ln S where: H' = Shannon Diversity Index (see above) S = number of species in the sample.

Benthic Response Index. The BRI measures the condition of a benthic assemblage, with defined thresholds for levels of environmental disturbance (Smith et al. 2001). The pollution tolerance of each species is assigned based upon its distribution of abundance along a pre- established environmental gradient. To give index values an ecological context and facilitate their interpretation, four thresholds of biological response to pollution were identified. The thresholds are based on changes in biodiversity along a pollution gradient. A reference threshold, below which natural benthic assemblages normally occur, was identified at an index value of 31, the point on the pollution vector where pollution effects first resulted in a net loss of species. Three additional thresholds of response to disturbance were defined at index values of 42, 53 and 73, representing points at which 25%, 50%, and 80% of the species present at the reference threshold were lost.

Cluster Analysis. The infauna population was grouped by station and species groups using cluster analysis. Rare species (those occupying fewer than one site within the survey area) were excluded from the analysis. Data were square root transformed. Spatial and temporal differences in benthic community structure were analyzed by normal (stations) and inverse (species) classifications using the Bray-Curtis Index of Similarity (Bray and Curtis 1957). Species arrays were grouped using Cluster Analysis (Clifford and Stephenson 1975). For normal (station by station) classifications the Bray-Curtis Index is:

s s B.C. = 2 Σ{min(nij,nik)} / Σ (nij +nik) where: nij = number of indiv. of species i at sta. j nik = number of indiv. of species i at sta. k s = number of species compared.

For inverse (species by species) classifications:

N N B.C. = 2 Σ {min(nji,nki)}/Σ (nji+nki) where nji = number of indiv. from station j of sp. i nki = number of indiv. from station k of sp. i N = number of stations.

10

54 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013

The cluster distances for stations and species were used to create a two-way coincidence table depicting the station-species abundance data matrix displayed as a table of symbols indicating the relative abundances of the species at the stations. The rows and columns of the table are arranged to correspond to the order of stations and species along the respective station and species dendrograms. Since similar entities (stations or species) will tend to be closer together along a dendrogram, the row and column orders will efficiently show the pattern of species over the stations and station groups.

Analysis of Variance (ANOVA). ANOVA’s were used to compare population variables and among stations. ANOVA analysis requires two steps. In the first step, differences in a variable among stations are evaluated to determine if they are sufficiently large to be statistically significant (p < 0.05). If they are, then a second test must be performed to determine which stations are significantly different from another station or stations. In this report, this second step is called the comparison of means. For example, a comparison of means stating: OS1 > OS2, OS3 > OS4, indicates that, for that particular variable, Station OS1 is significantly larger than Stations OS2, OS3, and OS4, and Stations OS2 and OS3 are also significantly larger than Station OS4. For chemical contaminants, if stations near the outfall are significantly higher than stations farther away, that compound should be evaluated further. For population variables, the opposite is true.

Results were correlated against distance from the outfall diffuser. When appropriate, correlations were designated as significant (p < 0.05) or marginally significant (0.05 < p < 0.10,) and expected (negative) or unexpected (positive). Since grain size can have an important effect on infaunal populations and the ability of contaminants to adhere to particles, results were also correlated against percent fine particle size. The expected sign for particle size would be negative (increasing concentrations with smaller size).

Data were also compared to results of the 2008 Carpinteria survey and “reference” sediments from uncontaminated areas collected and analyzed by the Southern California Bight Regional Monitoring Program (SCBRMP) in 2008. Finally, chemistry results were compared to the limits presented in two NOAA studies (Long and Morgan 1990 and Long et al., 1995). In these studies, researchers compiled published information regarding the toxicity of chemicals to benthic organisms. The data for each compound were sorted, and the lower 10th percentile and median (50th) percentile were identified. The lower 10th percentile in the data was identified as an Effects Range-Low (ER-L) and the median was identified as an Effects Range-Median (ER-M).

Physical and Chemical Analysis of the Sediments

Particle Size Analysis

Sediments at each of the five sites in the survey area were nearly 100% sand (range = 97 to 100%) (Table 3, Figure 2 and Appendix C). Median particle sizes were similar among the five sites, ranging from 137 to 190 µm. Fine sediments were nearly absent and gravel was not measured at any of the five sites. Sediments were narrowly distributed or homogeneous, indicated by the moderately sorted category (Gray 1981) at each of the sites and as depicted in Figure 2. The particle size distributions are indicative of a high energy environment where currents and surge are strong. The composition of the bottom in the survey area changes drastically from year to year (Aquatic Bioassay 2003 and 2008) due to the scouring and deposition of sand by currents or from nearby beaches through wave action.

Chemical Analysis

Table 4 lists all of the bacterial and chemical constituents measured from samples collected at each of the five benthic sediment stations. These compounds have been separated here into two main groups: undifferentiated organic compounds and heavy metals. Tables 5 and 6 compare the Carpinteria sediment chemistry results for 2013 with the 2008 Southern California Regional Monitoring Survey and the NOAA ER-L and ER-M values. The NPDES

56 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013 permit specifies that chemistry results normalized to fine sediments be presented. Since the sediments were composed of 100% sand this was not possible.

Undifferentiated Organics The undifferentiated organics in this report includes groups of compounds whose concentrations can help to determine the extent of anthropogenic contaminant loading in an area. These groups are discussed below:

 Biological oxygen demand (BOD) is a measure of the bacterial uptake of organic material in the sediments during aerobic decomposition. The BOD is greater in sediments with greater amounts of organic material.

 Total Kjeldahl Nitrogen (TKN) is the method used as a measure of organic nitrogen in water and sediments. Organic nitrogen is present due to the breakdown of animal products and includes such natural materials as proteins and peptides, nucleic acids, urea, and numerous synthetic organic materials (APHA 2012).

 Total organic carbon (TOC) is a measure of the amount of carbon derived from plant and animal sources. It is a better measure of the portion of a sample derived from these sources than is percent volatile solids (Soule and Oguri 1996).

 Sulfide (H2S) is an indicator of organic decomposition occurring particularly in anoxic sediments and characterized by a rotten egg smell. No sediment reference values are available for sulfides.

 Total and fecal coliform bacteria are present in the guts of warm blooded animals and their presence in the environment suggests sewage contamination. However, the sources of both total and fecal coliforms are in many cases not of human origin. Total coliforms are commonly found in the soil and on plants, while fecal coliforms are found in all warm blooded animals.

There was no clear spatial patterns in the concentrations of undifferentiated organics in the Carpinteria survey area. The concentration of each constituent was low and was similar across sites (Table 4). TOC and total sulfide concentrations, and total and fecal coliforms correlated expectedly (decreased at sites away from the outfall) with distance from the outfall, but these correlations were not statistically significant.

The average concentrations of undifferentiated organics reported in this survey were compared to results of the 2008 Carpinteria survey and the 2008 SCBRMP (Table 5 and 6). Both percent fine sediments and TOC concentrations measured in Carpinteria sediments in 2013 were below concentrations measured at similar depths during previous surveys. BOD and sulfides were not measured during any of the regional surveys. ER-L and ER-M threshold limits were not available for these constituents.

Heavy Metals Heavy metals in the marine environment are relatively ubiquitous and, with the exception of mercury, can normally be detected in sediments in low amounts. When anthropogenic sources increase sediment concentrations above levels that can be assimilated by benthic organisms, their assemblages can be impaired. For example:

 Arsenic is carcinogenic and teratogenic (causing abnormal development) in mammals and is mainly used as a pesticide and wood preservative. Inorganic arsenic can affect marine plants at concentrations as low as 13 to 56 ppm and marine animals at about 2000 ppm (Long and Morgan 1990). The USEPA (1993) gives a terrestrial range of 1-50 ppm, with an average of 5 ppm.

 Cadmium is widely used in manufacturing for electroplating, paint pigment, batteries and plastics. Toxicity in water to freshwater animals ranges from 10 ppb to 1 ppm, as low as 2 ppm for freshwater plants, and 320 ppb to 15.5 ppm for marine animals (Long and Morgan 1990). The USEPA (1993) places the terrestrial range for cadmium at 0.01 to 0.7 ppm, with an average of 0.06 ppm.

 Chromium is widely used in electroplating, metal pickling, and many other industrial processes. Chromium typically occurs as either chromium (III) or chromium (VI), the latter being considerably more toxic. Acute effects to marine organisms range from 2,000 to 105,000 ppm for chromium (VI) and 10,300 to 35,500 ppm for chromium (III). Chronic effects range from 445 to 2,000 ppb for chromium (VI) and 2,000 to 3,200 ppb for chromium (III) (Long and Morgan 1990). The terrestrial range is 1 to 1,000 ppm with an average of 100 ppm (USEPA, 1993).

 Copper is widely used in anti-fouling paints. Saltwater animals are acutely sensitive to copper in water at concentrations ranging from 5.8 to 600 ppm. Mysid shrimp indicate chronic sensitivity at 77 ppm (Long and Morgan 1990).

 Older paints and leaded gasoline are a major source of lead. Lead may be washed into the Harbor or become waterborne from aerial particulates. Adverse effects to freshwater organisms range from 1.3 to 7.7 ppm, although marine animals may be more tolerant (Long and Morgan 1990).

 Mercury is a common trace metal once used in industry and as a biocide. Acute toxicity to marine organisms in water ranges from 3.5 to 1678 ppm. Organic mercury may be toxic in the range of 0.1 to 2.0 ppm (Long and Morgan 1990).

 Nickel is used extensively in steel alloys and plating. Nickel is chronically toxic to marine organisms in seawater at 141 ppm (Long and Morgan 1990).

 Silver has many uses in commerce and industry including photographic film, electronics, jewelry, coins, and flatware and in medical applications. Silver is toxic to mollusks and is sequestered by them and other organisms. Silver increases in the Southern California Bight with increased depth; high organic content and percent silt (Mearns et. al., 1991). The range in the rural coastal shelf is from 0.10 to 18 ppm, in bays and harbors from 0.27 to 4.0 ppm, and near outfalls 0.08 to 18 ppm (Soule and Oguri 1996). The normal terrestrial level ranges from 0.01 to 5.0 ppm, with a mean of 0.05 ppm.

 Zinc is widespread in the environment and is also an essential trace element in human nutrition. It is widely used for marine corrosion protection, enters the waters as airborne particulates, and occurs in runoff and sewage effluent. Acute toxicity of zinc in water to marine fish begins at 192 ppm, and chronic toxicity to marine mysid shrimp can occur as low as 120 ppm (Long and Morgan 1990). The normal terrestrial range is from 10 to 300 ppm, with a mean of 50 ppm (Soule et al. 1996).

Of the eleven metals measured for this survey, all were above detection at each of the sites except for silver which was below detection at each site (Table 4). Each of the metals, except copper, correlated expectedly with distance from the outfall. None of the correlations were statistically significant. This indicates there were no outfall related spatial patterns in metal concentrations in the survey area. Four of the metals correlated significantly with sediment particle size (iron, lead, nickel and zinc).

The average concentrations of each of the heavy metals measured in this survey were compared to the 2008 Carpinteria survey and the 2008 SCBRMP (Table 5 and 6). Concentrations of arsenic, cadmium, copper, lead, nickel and zinc were slightly greater during the 2013 Carpinteria survey compared to 2008. Only chromium and nickel were slightly greater than concentrations measured at reference site by the SCBRMP (2008).

None of the metal concentrations measured in the Carpinteria survey area exceeded the ER- L and ER-M threshold values (Tables 5 and 6).

Biological Analysis of Benthic Sediments

Biological indices

A total of 6,665 individuals consisting of 208 species were collected at the five stations during the 2013 survey (Appendix E). Annelids represented 33% of the population, while arthropods (26%), echinoderms (6%), mollusks (32%) and miscellaneous phyla (2%) represented the remainder. The simplest measure of resident animal health is the abundance of infauna collected per sampling effort. Average abundance was similar across sites ranging from 101 at station R2E near the outfall terminus to 389 at station R3 500 meters west of the outfall (Table 7). Another simple measure of population health is the number of separate infauna species collected per sampling effort. In general, stations with higher numbers of species per grab tend to be in areas of healthier communities. Numbers of species were least at Station R2E (n = 29) and greatest at Station R1, located 500 m east of the outfall terminus. Neither abundance nor numbers of species correlated significantly with distance to the outfall. In each case station R2E near the outfall was significantly less by ANOVA compared to the sites further away. Species diversity indices are similar to numbers of species; however they often contain an evenness component, as well. For example, two samples may have the same numbers of species and the same numbers of individuals. However, one station may have most of its numbers concentrated into only a few species while a second station may have its numbers evenly distributed among its species. The diversity index would be higher for the latter station. For this survey, Shannon diversity (range = 2.93 to 3.24) and Simpson diversity (range = 0.87 to 0.94) were similar across sites. Neither index correlated significantly with distance to the outfall or among stations by ANOVA (p > 0.05) Species evenness (J) is a measure of the distribution of species across the total individuals collected at each site. As J approaches 1.0, the number of individuals for each species becomes equal. A more evenly distributed community is considered to be healthier. During this survey, evenness was significantly less at station R3 compared to the two outfall stations (R2E and R2W) by ANOVA (p>0.05). Margalef’s Richness was similar across sites (range = 6.14 to 9.86), as was Schwartz’ Dominance (range = 11 to 16). Neither of these indices were significantly correlated with distance to the outfall or among stations by ANOVA.

The BRI measures the condition of a benthic assemblage with defined thresholds for levels of environmental disturbance (Smith et al. 1997 and 2001). The thresholds are based on changes in biodiversity along a pollution gradient that was established for locations throughout the southern California bight at different depths. A reference threshold, below which natural benthic assemblages normally occur, was identified at an index value of 31, the point on the pollution vector where pollution effects first resulted in a net loss of species. Three additional thresholds of response to disturbance were defined at index values of 42, 53 and 73, representing points at which 25%, 50%, and 80% of the species present at the reference threshold were lost. BRI scores were well below the reference threshold (31) at all sites in the Carpinteria survey area, ranging from 1 at station R2E nearest the outfall to 13 at stations R3 and R1 (Table 7). This indicates that there was no net loss of reference species at these sites. There was no significant correlation with distance to the outfall for BRI scores, while outfall station R2E was significantly lower by ANOVA compared to each of the other stations. This indicates that the healthiest infauna communities were found nearest the outfall terminus.

Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013

Abundances, numbers of species, Shannon Wiener Diversity, evenness and Dominance measured during the 2013 Carpinteria survey were compared against the same metrics measured in 2008 at sites for the SCBRMP (Ranasinghe et al. 2011). Abundances and evenness found in the Carpinteria survey area were similar to those found during the Reference site survey (Table 8). Diversity, numbers of taxa and dominance were somewhat less than what was found during the reference site surveys.

Cluster Analysis

Spatial and temporal patterns of species composition in and around the Carpinteria outfall were evaluated for the 2013 survey using cluster analysis (Figure 3). Patterns of infauna distributions were determined by comparing normal (station x station) and inverse (species group x species group) classifications using the Bray-Curtis pair wise similarity index. Rare species (those with abundance less than five) were excluded from the analysis. Cluster analysis considers relative abundance of each tested taxa across the stations it occupies and is not weighted towards dominant species and therefore provides a more complete assessment of community structure. Cluster analysis delineated two station groups that were loosely organized based on distance from the outfall (Figure 3). Station group 1 included only outfall terminus site R2E. Each of the other stations was included in station group 2 and was progressively more dissimilar to R2E in the order: R2E, R4, R3 and R1. The greatest proportional difference between sites was 60%, indicating a relatively small difference in community composition between sites. The lower BRI score at the outfall site (R2E) indicates that the species found there were even closer to those found at Southern California reference site locations than those at the sites further from the outfall terminus. The two-way station by species table shows relative abundances of taxa across the site groups (Figure 4). Station group 1 includes only species in groups A and B, but shares these species across each of the station in group 2. Species in groups C and D are nearly excluded from station group 1, but are shared across site sites in station group 2.

Outfall Pipe Inspection

On September 1st, 2013, divers inspected the outfall pipe from its terminus at a depth of 35 feet to shore. The purposes of the survey were to inspect the physical integrity of the outfall pipe and note any impediment to flow from the diffuser ports. DVD copies of this survey are included with this report. The outfall dive survey was conducted between 10:00 and 14:30 hours aboard the research vessel Hey Jude. Weather conditions were clear with 10 to 15 knot winds from the west- southwest and a 4 to 6 foot swell from the southwest. Water color was brown to green and water visibility at the bottom was less than a foot, with a light 0.5 knot current. Divers, using a Sony Hi-8 Camcorder enclosed in a Gates underwater housing with attached NiteRider underwater lights, conducted the survey. Once the outfall had been located by global positioning (GPS) and bottom finder, a buoy, attached to a line and a weight, was deployed over the side (Latitude 34° 23.348’ N, Longitude 119° 31.381’ W). Divers entered the water, descended down the line, swam to the diffuser terminus, and began videotaping. Between dives, divers removed the camera from the housing, the footage was inspected, batteries were replaced, and the housing was reassembled. The footage was downloaded to computer files, and edited using Adobe Premiere software, then transferred to DVDs. The DVDs were then reviewed by the survey team to assess conditions of the outfall. The video is arranged from the deepest part of the dive (outfall terminus) down the east length of the pipe towards the shore where the outfall pipe disappears into the sand in approximately 3 feet of water. Then the west length of the outfall was filmed going from the surf zone to the outfall terminus. The end plate of the terminus was secure and the eight inch diffuser port at its center was flowing freely. During the 2011 survey, two large sections of pipe were undercut, however this survey revealed only two small undercut sections, running less than two feet each. These small sections of pipe are supported with rip-rap. Inspection of all the lateral diffuser ports on both the east and west sides of the diffuser showed that considerable attached biological growth surrounded each port. Divers cleared two partially obstructed ports on the west flank of the outfall pipe. All standup diffuser ports are now open and flowing freely. No evidence of leaks, damage, erosion, holes, or cracks were observed on any part of the diffuser.

Summary and Key Findings

The Carpinteria Sanitary District receiving water survey was conducted on August 8th, 2013 between 1200 and 1500 hours at five offshore stations located in the vicinity of the Carpinteria Sanitary District Treatment Plant outfall. The survey included ship based collections of sediment samples for physical, chemical and biological analyses of the benthic environment, and a visual survey of the outfall pipe and diffuser. Key findings for this survey are as follows:  Bottom sediments were composed almost entirely of sand (100%) at each of the five sites in the survey area.  Concentrations of sediment total and fecal coliforms were at or near the method detection limits in all cases.  There were no clear spatial patterns in the concentrations of undifferentiated organics (TKN, TOC, BOD and sulfides) in the Carpinteria survey area. The concentrations of each constituent were low and were similar across sites. TOC concentrations measured in Carpinteria sediments were below concentrations measured at similar depths during southern California reference site surveys.  Of the eleven metals measured for this survey, all were above detection at each of the sites, except for silver which was below detection. There were no outfall related spatial patterns in metal concentrations in the survey area. Of the eleven metals, chromium and nickel were slightly greater than concentrations measured during the SCBRMP (2008). None of the metal concentrations measured in the Carpinteria survey area exceeded the ER-L and ER-M threshold values.  The benthic infauna community in the vicinity of the Carpinteria outfall was composed of a rich assemblage of polychaete worms, crustaceans and mollusks during the 2013 survey. A total of 6,665 individuals, consisting of 208 species were collected at the five stations. None of the biological metrics were significantly correlated (p < 0.05) with distance from the outfall, indicating there was no outfall related spatial contaminant pattern. Infauna abundances and numbers of species were statistically lower by ANOVA at R2E, located nearest the outfall terminus. However, the Benthic Response Index (BRI) was significantly least at station R2E which means there was no net loss of reference species and indicating the healthiest infauna community of the five sites.

 Cluster analysis supported these findings and showed that outfall site R2E was most dissimilar to sites further away from the outfall. These results indicate that there may be an outfall related effect on the benthic infauna in the Carpinteria survey area. However the BRI scores at each site (including the outfall sites) were far below the reference threshold indicating that the infauna populations in the Carpinteria survey area were similar to those found at references sites throughout the southern California Bight.

Abundances, numbers of species, diversity, evenness and dominance measured during the 2008 Carpinteria survey were compared against the same metrics measured on the mainland shelf during the 2008 SCBRMP (Ranasinghe et al., 2011). Abundances and evenness found in the Carpinteria survey area were similar to those

29

73 Carpinteria Sanitary District, Receiving Water Monitoring Report December 2013

found during the Reference site survey. Diversity, numbers of taxa and dominance were somewhat less than what was found during the reference site surveys.

 The end plate of the outfall terminus was secure and the eight inch diffuser port at its center was flowing freely. Inspection of all the lateral diffuser ports on both the east and west sides of the diffuser showed that considerable attached biological growth surrounded each port. Divers cleared two partially obstructed ports on the west flank of the outfall pipe. All standup diffuser ports are now open and flowing freely. No evidence of leaks, damage, erosion, holes, or cracks were observed on any part of the diffuser.

STAFF REPORT

TO: Board of Directors

FROM: Craig Murray, P.E. - General Manager

SUBJECT: District Administration Building Replacement Planning Conditional Use Permit Status and Planning Discussion

DATE: February 18, 2014

REQUESTED ACTION: Board to review and discuss information and provide direction to staff as deemed necessary or appropriate.

FUNDING SOURCE: TBD

BACKGROUND: At the regular Board meeting on January 21, 2014 it was requested that staff present information at a future meeting related to the District’s administration building, specifically the Conditional Use Permit and associated requirements to replace the building on a time schedule. A discussion of this issue is appropriate at this time as the replacement schedule is now within a reasonable capital facility planning horizon.

Attached is a copy of a Technical Memorandum prepared by the District in late 2004 which provides an overview of the original administration building development and subsequent permit modifications. This memo was put together in response to negotiations with City of Carpinteria Community Development Department staff, and was followed by a process that culminated in a revision to the Development Plan and Conditional Use Permit (CUP) for the administration building. A copy of City Resolution PC-06-003 which adopted the permit revisions and set forth specific findings and requirements related to building replacement is also attached. Prior to 2004, the District was negotiating annual or bi-annual extensions to its CUP, which required extensive staff time and generated some level of recurring tension between the agencies.

At this point, in conformance with the updated permit requirements, the District is targeting a conceptual planning effort in FY 2015/16 that would analyze all of the options for on-site replacement and potential relocation of the administration building. It is anticipated that this effort would culminate in a solid implementation plan for execution.

RECOMMENDATION: None.

Carpinteria Sanitary District TECHNICAL MEMORANDUM

To: Richard Weinberg, Mayor Donna Jordan, Vice Mayor David Durflinger, City Manager Paul Kermoyan, Community Development Director

From: Pat Horwitz, Ad Hoc Committee Member Michael Damron, Ad Hoc Committee Member Craig Murray, General Manager cc: CSD Board of Directors

Date: November 3, 2004

Re: Carpinteria Sanitary District Administration Building – 5300 Sixth Street 90-558-DP/CDP (APN 003-332-015)

This Technical Memorandum was prepared following a July 7, 2004 meeting between the Carpinteria Sanitary District (District) and the City of Carpinteria (City), held to discuss the permit status of the District’s existing administration building located at 5300 Sixth Street. The District is respectfully requesting the City’s consideration of a modified schedule for administration building improvements. The basis for this request was discussed at the July 7th meeting and supporting information is provided herein for your review.

1.0 BACKGROUND

The District’s existing administration building was originally constructed pursuant to Development Plan 90-558-DP, effective on April 1, 1991. The building was permitted as a temporary structure at that time. A variance was required because the finish floor elevation was slightly lower than the base flood elevation. A condition of the permit required the District to submit an appropriate Development Plan for a permanent building prior to April 1, 1996. The existing building is a modular office building, totaling approximately 3,500 square feet. A redwood deck and ADA access ramp were constructed around the perimeter of the structure. Aesthetic grading and landscape improvements were also incorporated into the site design. The building site is located on Sixth Street, west of Olive Avenue. This portion of Sixth Street is a dead-end street and the only regular traffic passing the structure is associated with the Lou Grant Parent Child Workshop, also a modular building, and several manufactured homes occupied by employees of the State Park. The District has never received a documented complaint about the physical appearance of its Administration Building. We have, however, received correspondence indicating appreciation for maintaining the park-like setting on the subject parcel.

125 In April 1996, the Planning Commission approved a five-year extension to the Development Plan submittal requirement, revising the deadline to April 1, 2001. The District began efforts to prepare a Development Plan for replacement of the structure, or potentially for major structural improvements that would achieve “permanent” status for the existing building. In April 2001, the Planning Commission granted a one-year extension to the DP submittal requirement, revising the deadline to April 1, 2002. On April 1, 2002, the City Planning Commission approved an additional five-year extension to the Development Plan submittal requirement, on the basis that the District had abandoned plans to replace or modify the existing structure in favor of constructing a new administration office on the site of the District’s wastewater treatment plant. Very preliminary plans for this approach were prepared by Bill Cooper, the District’s architect, in support of this request. The extension was also allowed due to the District’s expressed need to commit capital improvement funds to repair and rehabilitation of subsurface sewer pipelines. It should be noted that the extension was approved with the mutual understanding that it would be the last extension considered by the Planning Commission. Since 2002 the District has continued to evaluate the possibility of constructing a new administration building at the wastewater treatment plant site. While feasible, we have identified access constraints and other issues that make this approach challenging to implement. The District is also considering the fate of the existing administration building parcel. The parcel is currently zoned Industrial (M), however, its land use designation in the City General Plan is Public Facility. If this parcel is to be vacated, the District would like to pursue rezoning to a medium density residential use in conjunction with the in-progress Citywide zoning map update. The parcel would likely be sold to fund construction of the new administration building, although the District has considered various other development options, including workforce housing. Prior to moving forward and committing funds to design a new administration building, the District reformed its Ad Hoc committee to confirm this direction. The Ad Hoc committee attended the July 7, 2004 meeting with City staff and council members to discuss implementation issues.

At the meeting the District advanced the idea that replacement of the existing administration building should in some way be tied to the remaining useful service life of the structure. This concept was discussed and the following justifications were put forth.

• The existing administration building fully meets the needs of the District and its constituents at this time. • The existing structure is consistent with neighboring land use and building types. • Construction of a new administration building would likely cost in excess of $1M of existing ratepayer money. • Insufficient funds were allocated in the District’s 2002-2009 CIP to construct a new administration building. • The District, under mandate from US EPA, must fund a major, near-term capital program to replace or rehabilitate large portions of its sewer collection system. • Sewer service charges were recently increased to fund these pipeline improvements and they have higher priority than building replacement. At the meeting the District committed to investigate two key issues: 1) the actual remaining useful life of the existing modular building, and 2) the actual finish floor elevation of the

126 structure relative to the 100-year floodplain elevation. This memo provides an overview of these follow-up investigative efforts and proposes an updated schedule for building replacement.

2.0 STUDY FINDINGS

Findings on the condition of the existing modular structure and the finish floor elevation are presented below.

2.1 Administrative Building Physical Condition District staff contacted Golden Office Trailers, the vendor who originally supplied the modular building. It was their opinion that, if properly maintained, a pre-manufactured building of this type could remain serviceable for thirty years or more. The modular building provided to CSD in 1991 was a relatively high-end model, particularly with respect to interior trim and mechanical systems. Staff inquired about potential building inspectors or contractors known to Golden Office Trailers, who could provide an estimate of remaining useful life. It was recommended that a local certified building inspector, with experience evaluating modular buildings, be used for this service.

Several local building inspectors were contacted and the District selected Independent Building Inspections (IBI), of Santa Barbara, to perform the building inspection based on their experience with modular buildings. A comprehensive building inspection was performed by Mr. Gil Hoeflich on July 22, 2004.

The complete Inspection Report and a letter from Mr. Hoeflich rendering an opinion as to remaining building service life are attached herewith for reference. Generally, the existing administration building was found to be in satisfactory condition. Limited moisture damage was noted in exterior walls and trim. Misaligned windows and doors suggest that some amount of settlement has occurred, possibly due to drainage problems beneath the structure. Remedial recommendations put forth the inspection report include leveling of the modular building by a licensed contractor, surface drainage improvements, repair of moisture damage, termite inspections and other minor mechanical and structural repairs.

IBI estimated that the structural components of the modular building have an estimated life expectancy of 10-15 years. Based on input from the building manufacturer, this estimate is believed to be conservative but not unreasonable. With proper maintenance, District staff is confident that the building will remain serviceable for no less than 15 years. A building replacement schedule that is consistent with this estimate is proposed.

2.2 Administrative Building Finish Floor Elevation The District engaged Penfield & Smith Engineers (P&S) to determine the actual elevation of the Administration Building with respect to the 100-year floodplain elevation. In 1993 P&S prepared a Letter of Map Revision (LOMR), in conjunction with the District’s wastewater treatment plant upgrade, which slightly modified the floodplain boundary in the vicinity of the District-owned parcels.

The attached Elevation Certificate shows the finish floor elevation of the existing Administration Building is 17.80 feet (NGVD 29 datum). The base flood elevation at the site was determined to be 18.00 feet. Therefore, the building is 0.20’ or 2.4” below the 100-year

127 floodplain elevation. The analysis was based on FIRM Panel No. 060332 005 E, as revised by the LOMR dated July 29, 1993.

This deviation is inconsistent Section 15.50.190 of the Municipal Code, which requires the finish floor of a manufactured building to be at or above the base flood elevation. However, the District does not feel this minor deviation warrants the significant expense of raising the structure and/or constructing permanent foundation elements. The building is appropriately restrained against flotation and local topographic conditions suggest that very low water velocities would be experienced during the 100-year flood. The District’s critical facilities, from an operations perspective, are located at the wastewater treatment plant site. During periods of flooding administrative functions could be performed from the operations building.

Any future development of the subject parcel would be designed and constructed in strict accordance with applicable Municipal Code requirements.

3.0 RECOMMENDED IMPROVEMENT SCHEDULE

The existing modular Administration Building meets the needs of the District at this time. The District’s understands the City’s concerns regarding the “temporary” nature of the modular building. Based on information generated as part of this review, the District proposes an improvement schedule that includes interim structural and aesthetic improvements and a commitment to construct a new, permanent building within a reasonable time frame. This proposed schedule, which the District believes represents a more prudent use of public funds, is outlined below.

3.1 Near Term Building Improvements Routine building maintenance will continue and will be stepped up as necessary to address minor issues and problem areas described in the IBI Inspection Report. In addition to ongoing maintenance activities the following improvements are proposed in the near term:

• FY 2005/06 Structural / Mechanical Improvements. The District will hire a qualified contractor to adjust the height (level) of the building and to repair/replace defective structural components of the modular building. Moisture damage and other identified structural defects will be repaired concurrently. Substructure drainage will also be improved as recommended.

• FY 2006/07 Exterior Aesthetic Improvements. The District will paint the exterior of the building, refinish the deck and exterior trim, and make minor architectural enhancements as appropriate. Additional landscaping improvements will be completed to improve the exterior appearance of the structure and related mechanical systems.

3.2 Administration Building Replacement The District proposes a schedule for replacement of the existing Administration Building that is consistent with the obtained estimate of remaining useful life, but far enough into the future to allow us to focus resources on repair and rehabilitation of critical buried infrastructure within the City. The proposed replacement schedule is outlined below:

• FY 2016/17 Conceptual Design. The District will select an architectural firm and

128 support team to prepare concept design of a new Administration Building. The conceptual design would be submitted to the City for review.

• FY 2017/18 Working Drawings / Project Approvals. Building design will be advanced to the working drawing stage and project approvals and development permits will be procured from the City.

• FY 2018/19 Break Ground / Begin Construction. Construction of the new Administration Building will commence in this fiscal year. An 18 to 24 month construction period is anticipated.

• FY 2019/20 Complete Construction / Occupy Building. Construction will be completed and District staff will occupy the new Administration Building during this fiscal year.

4.0 PERMITTING AND IMPLEMENTATION

Assuming that City staff and the applicable governing bodies could support the proposed administration building replacement schedule, the District would consider entering into an agreement with the City or participating in a memorandum of understanding to provide decision makers formal assurance that the agreed upon schedule will be adhered to.

Under such an agreement, the District would support rezoning of the administration building parcel to be consistent with the “Public Facility” land use designation in the City’s General Plan. The District would also agree to retain and restrict the $375,000 in its current CIP (FY 06/07) and to commit additional funds necessary for building replacement after completion of required buried infrastructure improvements.

We hope that the information provided in and transmitted with this memorandum provides City staff and City representatives with sufficient information to consider a modified implementation schedule. We look forward to convening with you again to continue discussion of this important matter.
