Exhibit A Scope of Work Objectives: • Assess the structural integrity of CMSD's underground sewer pump stations to determine their seismic-resistant design and vulnerability in the event of an earthquake of a magnitude 6.0 or greater. • Determine probable costs for seismic rehabilitation based on current seismic criteria. Scope of Work: • Conduct a sampling of 14 pump stations to determine preliminary seismic rehabilitation schemes. • From the evaluations of these 14 pump stations and the resulting strengthening schemes an overall district-wide approximate cost for seismic improvements will be developed. Cost must include preparing designs, plan checks with CMSD and the City of Costa Mesa's Building Department and construction. • Review previous seismic evaluations. • Develop a rating system to target the most hazardous pump station for seismic improvements. These seismic improvements should focus on preventing pump station collapse and failure of the system after an earthquake. • Observation, analysis and conclusions contained in the final report must reflect best structural engineering judgment. • The evaluations will include field reconnaissance to observe the general physical status of pump stations in an attempt to confirm the structural information shown on the existing drawings. • No testing or demolition of finishes to expose the existing structural elements will be conducted to determine their material properties. • Submit one original final draft study to the District 10 „u ' 4 �BL� O G ' T f RUL"N"i Q�V.. o G�� I v`$ r I$�neNf .°��T�.'T 4 �-� ��T � I .✓ � ) r; r r #- .vq;�4 t �, �� _��I �v �B�IQ �I��� �ter' r w.,*n•w � �w �������� l q q�� �b a u 77 s.µ - '� � '"�r �.�r4�.�- ..� a.- � � , hi sill TE u t�P ,q,r Driai »w `4 I eke Ets>rzae t N, r c'O a� Q r ana 1� "t N „ s0 ,, 5.� 1 0 F r y � r ,I a �j 05DATASOURCE:CALIFORNIA GEOLOGICAL SURVEY(CGS]:ENVIRONMENTAL SYSTEMS RESEARCH INrMUTE(ESRI) REFERrNCE:JENNINGS,7994,FAULTACTWITY MAP OF CALIFORNIAAND ADJACENT AREAS LEGEND nN IL FAUL TACTIVITY: LATE QUATERNARY A HISTORICALLY ACTIVE (POTENTIALLY ACTIVE" a HOLOCENE ACTIVE M.. .

Overview of the proposed new WDR On Thursday,March 24, 2011 the State Water Resources Control Board(SWRCB) released for public comment its revised Waste Discharge Requirements (WDR) for Sanitary Sewer Systems. If adopted, the new WDR will replace the current statewide WDR Order No. 2006-0003 which was adopted in May of 2006. The new proposed Order has been entirely rewritten and includes both major and minor changes. Even the name has been changed from Sewer System Overflow Waste Discharge Requirements (SSOWDR) to Sanitary Sewer System Waste Discharge Requirements (SSSWDR). Below is a brief overview of some of the changes in the new proposed SSSWDR. • The definition of who qualifies under the program has been changed to include a flow value as well pipe length component. Under the new proposed SSSWDR, sanitary collection systems that have one or more miles of contiguous pipe length and collect and convey 25,000 gallons of untreated or partially treated wastewater on any single day qualify for enrollment in the program. • Private (trailer parks, private communities, commercial complexes, etc.) and federal (military bases, etc.) systems that meet the qualification of pipe length and flow volume also must enroll in the program and develop a certified system specific Sewer System Management Plan(SSMP). • Private property spills, referred to as Private Lateral Sewage Discharges (PLSD) require mandatory reporting by the public agency within whose jurisdiction the spill occurred as the public agency becomes aware of them. Currently only Region 9, San Diego, requires the reporting of private property spills. • Under the current SSOWDR discharges to the waters of the U.S. constitute a category I spill. Under the new proposed SSSWDR waters of the U.S. has been replaced with surface waters of the state. In the definitions, surface waters of the state means any surface water, including saline waters, within the boundaries of the state excluding groundwater. Included are storm drains and drainage channels that are tributary to surface waters of the state. • New Enrollees, those who are now eligible for enrollment but were not eligible under the current WDR, will have 6 months to apply for enrollment. Current Enrollees are required to submit a new application package for coverage under the new proposed SSSWDR. Within 60 days of adoption of the new proposed SSSWDR the State Water Board staff will send specific instructions to all current and known potential Enrollees on how to apply for coverage. • Discharges of chlorine, including chlorine residual such as that in potable wash water, or any other toxic substance used for disinfection are prohibited. Some changes proposed in the SSMP: • In the Organization element the names, phone numbers and email addresses of the current governing body must be included along with the contact information for the agency's staff, The website address where the Enrollee's SSMP is posted, if applicable,must be listed, • Under the Legal Authority two new requirements have been added. One is the authority to limit flows to the sanitary sewer system from connected sources including laterals and satellite systems. The second is the authority to ban new connections. Also, under the Legal Authority the Enrollee shall specify whether they own or maintain sewer laterals or portions thereof including pipe, cleanouts, and backflow prevention devices. Policies, procedures related to the requirements for easements shall be addressed in this section. • In the Operations and Maintenance element any contractors doing routine work for the implementation of the SSMP must be identified along with a description of the services provided. • The Enrollee must also describe any private lateral inspection or replacement programs implemented. • A Staff Assessment Program must be developed that annually assess the proficiency of the operations and maintenance staff including supervisors, contractors and others having oversight or the collection system operation. • A Contingency Plan that identifies the most critical collection system assets and procedures posing the highest risk for an SSO must be developed. • O&M and system replacement budgets that include costs,revenue and revenue sources must be included in the SSMP. • The Overflow Emergency Response Plan must include documentation on the steps needed to prepare for natural disasters and hazardous weather events. A risk and threat analysis prioritizing the highest risks and threats to the collection system must be completed and must include the consequences of each indentified failure. • The FOG element remains basically the same only under the new proposed SSSWDR staffing levels need to be identified for the inspection and enforcement of the FOG ordinance. • In the System Evaluation and Capacity Assurance element professional evaluation and judgments must be provided by a professional engineer registered in California. Budgets showing costs, revenue and revenue sources for the System Evaluation and Capacity Assurance Plan must be included in the SSMP. • The Monitoring Measurement and Program Modification element has been changed to Performance Targets and Program Modifications. In this element in the new proposed SSSWDR the Enrollee is to create and track performance targets linked to elements of the SSW to measure the effectiveness and success of the SSW elements. A change log shall also be maintained tracking the modifications and changes that occur in the SSMP. • The SSMP Program Audits element has been enlarged to include more definition of what the state is looking for in the 2 year audits. • The Communications element requires annual communication with the public on the SSW development and implementation and annual communication with satellite systems. • Re-certification of the SSW by the governing body is now required every 4 years with re-certification to the California Integrated Water Quality System (CWIQS) on-line database every 2 years. The SSW is to be posted to the Enrollee's internet site and if not posted than an electronic copy of the SSW must be uploaded to CWIQS every time the SSMP is re-certified. • There is a new schedule of compliance deadlines based upon population served for new Enrollees. For new public system Enrollees that qualified for enrollment under the current SSOWDR but did not do so the compliance schedule will be set by the Water Board staff. There are numerous other new clarifications, references and changes in the new proposed SSSWDR that require careful reading to determine the effect that they might have on your agency. Some are small and easily missed such as in Section D. 6 which describes the State and Regional Boards responsibilities in an enforcement action. Here the word "will" has been replaced by the word"may". Currently the State or Regional Boards are required to consider items (a)thru(g) of this section during an enforcement action, Under the new proposed SSSWDR, with the inclusion of the word may, the State and Regional Boards are not obligated to make those considerations. This language was included in the original WDR to ensure that during an enforcement action the efforts of the Enrollee to prevent SSOs would be considered regardless of which Region the infraction occurred. The Monitoring and Reporting Program (MRP)has also been substantially rewritten. The areas of note are the inclusion of the mandatory reporting of Category I and II PLSDs; the one call notification process to CalEMA; and that reporting will become event based as opposed to the current location based reporting. The records keeping requirements have updated. The new proposed SSSWDR is open for public comment until 12:00 noon on Friday April 29, 2011. The state is also soliciting comments on a two-tiered permit approach where any covered Enrollee that has a Category I spill that reaches the waters of the U.S. have their WDR converted to an NPDES Permit. Written comments can be mailed to: Jeanine Townsend, Clerk to the Board State Water Resources Control Board 1001 1 Street, 24th Floor Sacramento, CA 95814 An electronic .pdf copy of the new proposed SSSWDR and supporting documents is available at: htip://www.waterboards.ca.gov/water issues/ rograms/sso/review update.shtml r "Rob Hamers"<rbhinc@pacbell.neb ;.

Furthermore, it is unclear how the additional information that must be generated will be used by the Water Boards or that the efforts required under the revised permit will produce corresponding environmental or public health benefits. • The SSS WDR would expand liability for SSOs by including all spills to surface water as prohibited SSOs subject to enforcement, instead of only those reaching a "water of the United States." • The proposed SSS WDR would transform the existing enforcement discretion language, which expresses a clear statement of the State Water Board's intent regarding enforcement priorities and responses, into a purely advisory provision, which individual regional boards are fr ee to follow or ignore as they choose. + The SSS WDR is overly focused on private sewer laterals ("PSL"), requiring reporting of PSL spills by enrollees who have no authority over the privately owned laterals and requiring detailed information regarding local lateral programs. • The SSS WDR would include a new prohibition on the use of chlorine during spill cleanups, including any potential chlorine residual in potable water, thus making it very difficult to wash down and fully clean up and disinfect SSOs on roads and gutters, and in storm drains or ditches, Some key points you may wish to include in your letter with regard to the positive aspects of the SSS WDR as proposed: Revisions to streamline spill notification points of contact Modifying applicability criteria to include a flow threshold (>25K gallons on any single day) and a pipe mileage threshold (>1 mile) Expanding coverage of the SSS WDRs to private collection systems meeting the pipe mileage and proposed flow threshold. Clarifying that SSOs to land are not the focus of the SSS WDR Though not part of the State Water Board staff proposal, the State Water Board is also seeking comment on whether to adopt a "hybrid" two-tiered approach to regulation of sanitary sewer systems. We urge you to oppose this alternative. Under the two-tiered WDRs and NPDES permit: (1) enrollees who have had at least one SSO that has reached waters of the United States would be required to seek coverage under the NPDES permit-, (2) enrollees who have never had any SSO that has reached waters of the United States would be required to seek coverage only under the WDRs; and (3) when an Enrollee covered under the WDRs reports an SSO that has reached waters of the United States, the Enrollee would be required to switch coverage from the WDRs to the NPDES permit, The NPDES permit (as does the SSO WDR) would include a prohibition against all SSOs to waters of the United States_ As the SSS WDR does not authorize any SSOs to waters of the United States, there is no need for an NPDES permit. The result of such a change would be to subject local public agencies to additional citizen group lawsuits and higher administrative penalties with absolutely no demonstration that this would improve water quality or reduce SSOs. This alternative would also require additional Water Board staff resources to track and implement the different permit tiers. The proposed SSS WDR, staff report and related documents are posted on the State Water, Bard websirte.

We found that the operating nut was detached with a portion of the valve shaft still lodged in the operating nut. The appearance of the broken shaft appeared to us to have been sheared off by force (there was no indication of deterioration of the metal); we therefore assume that the valve was frozen in the open position prior to an attempt to operate it. . We also opened and inspected the valve vault and bypass manhole. The exterior of the valves in the valve vault appear to be in good condition and the check valves appeared to be of a more recent vintage than the plug valves. We assume these plugs valves have been exercised and should be in good working order. The piping in the bypass manhole showed definite signs of long term corrosion. This pump station is built into the slope of a hill utilizing a retaining wall to provide working area. The surface around the pump station and valve vault is completely covered with a concrete surface that extends from the retaining wall to the street. .To effect a replacement of the defective valve: one, a majority of the concrete surface will be removed; two, the valve will have to be excavated by hand; three, the piping from the valve vault discharge to the defective valve will have to be removed in order to effect a replacement. Our opinion of the existing piping is guarded given the corrosion and age we saw; it may be necessary to replace the piping from the valve vault up to the new valve. -It is also our opinion that the outlet valve and piping to the bypass connection is also suspect.We thank that once you spend the money to demo..and excavate the site it only makes sense to repair everything that is.suspect at the time-it is exposed. The District has and has had plans to eliminate some of the lift stations in this area; it may well be that this station will not need to function for a long period of time. This station could be bypassed (but only if the bypass valve functions) using the valve vault valves as the line shutoff. You might be able to limp through this immediate problem by doing nothing at all' The risk is not so obvious — if something breaks or malfunctions it will truly be an emergency.with emergency costs. We spoke briefly with Rob Hammers about the conditions we saw and to make certain of the pipe diameters we were dealing with. The information about the life expectancy of the station (3 years or longer) and the extent of necessary repairs was in part from this conversation. We suggest that you pay a field visit to this site to verify what we have observed and to determine what you want to replace. The range of costs is in the order of$6,500 to $10600 dependent on what you decide.
