APPROVAL OF EMERGECY REPAIRS TO 16-INCH PIPELINE IN NORWALK BLVD. AT HAWKINS STREET IN SANTA FE SPRINGS

SUMMARY:

At approximately 1:00 PM on August 12, 2020, Inframark contacted CBMWD Engineering and Operations staff and informed us that they were informed by the City of Santa Fe Springs that there was a huge leak in the Recycled Water main line. Inframark proceed to the site located on Norwalk Boulevard at the intersection with Hawkins Street. Water was flowing though displaced pavement and flooding the street. Inframark informed us they were planning to call out Doty Brothers to effect repairs and proceeded to shut down the flow of water to the leak. The leak was shut down by 3:00 PM by closing 4 inline valves.

Engineering and Operations Staff contacted the regulatory agencies via phone call and email and informed them of the spill and will prepare and submit a full report of the incident..

At approximately 4:30 PM Traffic Solutions set up traffic control and at approximately 5:00 PM Doty Brothers started exposing the main. There was a crack along the bottom of the 16-inch main. A 20 foot section of pipe was cracked and replaced with ductile iron pipe. The repair was completed at 3:30 AM and the traffic control was moved to the side of the road and all lanes of Norwalk Blvd. were opened.

Inframark is compiling the billings and will provide an estimate of costs for the repair. PROCUREMENT PROCESS:

The services were procured according to the Administrative Code: Emergency Repairs & Services – Repairs and Services performed on District’s facilities that are unplanned, unexpected and which are essential for the continued operation of the District facilities as determined by the General Manager.

At that time the District did not had a General Manager so in the absence of a General Manager, Engineering and Operations Management Staff made the determination.

Mr. Russel Yoshida

Sanitation Districts of Los Angeles County 1955 Workman Mill Road

Whittier, CA 90601 Dear Mr. Yoshida:

Central Basin Municipal Water District Unauthorized Recycled Water Discharge

On Wednesday, August 12 2020, an unauthorized discharge of disinfected tertiary-treated recycled water in the Central Basin Municipal Water District (CBMWD) service area occurred in the City of Santa Fe Springs at the intersection of Norwalk Boulevard and Hawkins Street. CBMWD uses recycled water that is produced at either the Sanitation Districts of Los Angeles County’s Los Coyotes or San Jose Creek Water Reclamation Plants (the CBMWD recycled water distribution system from these two plants are intertied in the City of Santa Fe Springs). The source of water serving the City of Santa Fe Springs area is a blend between the two plants.

CBMWD submits this letter in accordance with Section D.5 of Order Nos. 87-50, 87-51, and 97-072. CBMWD was notified about the leak by the City of Santa Fe Springs on Wednesday, August 12 2020 at approximately 1:25 P.M. CBMWD notified the L.A. County Sanitation Districts, The Regional Water Quality Control Board and the Los Angeles County Department of Public Health of the leak on Wednesday, August 12 2020 at 2:25 P.M.

Location and Cause of the Discharge

The unauthorized discharge occurred in the City of Santa Fe Springs at approximately 12:30 P.M. at the intersection of Norwalk Boulevard and Hawkins Street in the City of Santa Fe Springs (Figure 1). Around this time, the City of Santa Fe Springs was notified about a water leak at this location from an unknown source. Upon discovering the leak, the City notified Inframark, CBMWD’s operations contractor. CBMWD distributes recycled water to this area through a 16 inch PVC distribution main line. The cause of the leak was a crack and rupture of the 16 inch PVC pipeline. Inframark arrived onsite and notified CBMWD at approximately 1:25 P.M., and proceeded to contact the on-call construction company DOTY Brothers to

EXHIBIT "B"

address the leak and make the necessary repairs. Around this time, CBMWD received several calls from recycled water site owners regarding a loss of pressure at their sites. Also around this time, Inframark shut off CBMWD’s Rio Hondo Pump Station in order to reduce the flow. At approximately 3:00 P.M. Inframark notified CBMWD that the leak had been isolated and halted by closing several distribution system valves on either side of the leak location. DOTY Brothers arrived at approximately 4:00 P.M. to begin the repair work for the leak. The repair was completed overnight, and recycled water service was restored on Thursday August 13 2020 at approximately 7:00 A.M. The attached photo Exhibit “A” contains contextual photographs of the location before and after this leak event.

Volume and Flow Path of Discharge

The discharge from the leak was estimated by CBMWD to be approximately 36,000 gallons total. The discharge from the leak was estimated by approximating the flow rate from the leak on the 16 inch distribution pipeline over the estimated period of time discharging. Considering that the leak began at approximately 12:30 P.M. and was addressed by 3:00 P.M., and that the estimated discharge rate is 400 gallons per minute, the total discharge is estimated to be around 36,000 gallons total.

Once discharged, the recycled water flowed South on Norwalk Boulevard for approximately 50 linear feet, going into the catch basin on Norwalk Boulevard. Upon entering the catch basin, flow was routed South-West through the subsurface pipeline storm drain system (Figure 2). The total flow path of the discharge is estimated to be approximately 3.74 miles. Photographs of the storm drain outlet taken during the leak event are also included as part of Exhibit “A”.

Impacts from the Discharge

No major impacts are anticipated from this incident. Any chlorine residual from the recycled water is expected to have dissipated due to the low discharge volume and distance from the leak to the nearest catch basin. In addition, the receiving recycled water entry point to the storm drain system, in this instance, are concrete-lined channels that support very limited biological communities.

Measures to Prevent Recurrence

This event was an unforeseen incident that is not anticipated to occur again. CBMWD staff will work with the City of Santa Fe Springs to ensure the proper notification and emergency contact information is available to the site supervisor for this location.

Hello All,

I have tried to reach out to you all this afternoon to provide a formal notice of a recycled water spill. This email is to confirm the notice.

At approximately 12:30pm CBMWD was notified by the City of Santa Fe Springs and a recycled water customer in that area that they had experienced a loss of pressure. The District's operations team, Inframark, was dispatched, and found a major leak in the City of Santa Fe Springs, located at the intersection of Norwalk Boulevard and Hawkins Street. The operations team are currently working to fix the leak.

We do not yet have an estimate of the total water discharge. We plan to have a full report on the incident within the required 3-day reporting period.

If you have any questions please do not hesitate to contact me. Thanks,

-Donald

SEPTEMBER 28, 2020 - Board Meeting Prepared by: Robert McVicker, P.E, D.WRE Submitted by: Erin Maciel

Approved by: Dr. Alejandro Rojas

RECYCLED WATER SUPPLY AND DELIVERY CAPACITY SUMMARY:

At its August 12, 2020 meeting the Committee requested that staff bring back an evaluation of the capacity of Central Basin’s recycled water system to deliver water. The capacity of the system to deliver water is dependent on the supply source capacity and the pipeline capacity to deliver the flow at a prescribed pressure to a specified location.

The capacity of the pipes to deliver water at a prescribed pressure is dependent on the size (diameter) of the pipe, the characteristics of the supply pumps, the length of pipe between the supply and the demand and the amount of demand. Prior modeling has evaluated scenarios and found that the distribution system is robust in that it can supply large amounts of water throughout Central Basin’s distribution system. The theoretical amount of water that can be delivered is not particularly meaningful for evaluating the capacity of the recycled water system.

The capacity of supply is dependent on the treatment capacity and pumping capacity that is connected to the recycled water distribution system. Central Basin has two large capacity pump stations, the Rio Hondo Pump Station and Cerritos Pump Station that take water from the treatment plants to supply water to its customers though the distribution system. There is sufficient pumping capacity in the two pump stations to deliver water for the projected demands from the treatment plants. The supply pumping capacity is also not particularly meaningful for evaluating the supply capacity of the recycled water system.

The limitations on the supply and demand of the system is more meaningful in determining the amount of water that can be delivered and sold by Central Basin through its recycled water system.

The demand limitations are primarily due to the customer needs and their locations. Potential customers have been identified and the limiting factor to supply new customers is usually the economics based on the cost to construct additional pipe to serve the new customers. Typically the capital cost is such that the payback to recover these costs from water rates is too long to be economically feasible without significant grant funding.

The supply limitations are due to our purchase agreement with LACSD and their limitations based on complying with Water Code Section 1211 requirements.

(19)

Water Code Section 1211 Requirements

District staff met with LACSD regarding Water Code Section 1211 impacts in May of 2018. At that time, LACSD informed District staff they had been facing challenges with the California Department of Fish and Wildlife (CDFW) regarding new recycled water projects and the connection of new recycled water sites due to habitat downstream of the San Gabriel River. LACSD went on to state the main concern was due to the Least Bell’s Vireo, habitat vegetation, coupled with the reduction of recycled water supplies due to conservation measures throughout the region. The Water Code Section 1211 constraints are currently limiting LACSD’s ability to reduce discharges to surface waters in order to supply more recycled water to end users such as Central Basin. Since then, LACSD has placed a temporary restriction on use of additional recycled water supplies until they complete the environmental process required to satisfy State Law.

On June 2, 2020, the LACSD notified District staff that Wastewater Change Petition WW0106 for Los Coyotes Water Reclamation Plant had been approved and an Order Approving Change In Place Of Use, Purpose Of Use, and Quantity Of Discharge had been issued by the State Water Resources Control Board (Exhibit B). The LACSD also confirmed that the temporary supply restrictions on the District’s contracted recycled water supply from Los Coyotes have been lifted. It is important to note that temporary supply restrictions for San Jose Creek Reclamation Plant remain in effect until Wastewater Change Petition WW0107 is approved.

Water Purchase Contract

Central Basin and LACSD staff were able to come to agreement on terms for the purchase contract that would allow for expansion for Central Basin but not overcommit the scarcest supplies of recycled water from LACSD. The following represent the existing contract’s major terms that were approved by the Board in February of 2015:

1. The two preexisting contracts are rolled into one purchase agreement; 2. Maximum water available is reduced from 23,000 AFY to 10,500 AFY;

a. No more than 6,000 AFY can be pulled from the SJCP; b. Remainder must pulled from LCRP;

c. Additional water can be granted in the future if Central Basin proves demand and supply is available;

d. Available water can be reduced if not used within five years; 3. The term is 25 years from effective (approval) date;

4. Minimum price transitions from 20% of LACSD O&M costs to 30% to be on par with other LACSD contracts;

a. Transition time-minimum price increases 2% per year for years until at 30%. A copy of the entexisting contract inclusive of the above terms and conditions is attached as Exhibit “A”.

(20)

Current Contractual Issue

This contract agreement is financial in nature as a purchase agreement; however, there are operational aspects of this agreement that have come into the spotlight that need to be addressed.

The current temporary supply restriction directly challenges the term in 2(d) listed above.

Amendment to Contract

Central Basin staff has been working with LACSD to prepare an amendment to our current agreement which will postpone supply reductions during the period of July 1, 2019 through June 30, 2021 (the “Suspension Period”), with the opportunity to extend the Suspension Period through the Fiscal Year ending June 30, 2022. This was done with consideration of the current supply restrictions that prevent Central Basin from expanding the use of recycled water and to avoid reductions in supply allotments. The amendment has been reviewed by Central Basin’s current Interim Legal Counsel and is attached to this memo as Exhibit “B”. Section 6.3B, in the existing agreement, currently reads as follows:

“6.3. Adjustments to Allotment. The District may adjust Central Basin' s allotment as follows:

B. Decreases. If the Chief Engineer determines that Central Basin voluntarily, or without sufficient cause, failed to draw or beneficially use all or any part of its allotment for a consecutive 5-year period of time, then Central Basin will forfeit its right to the average of the unused portion, and Chief Engineer will reduce Central Basin' s allotment accordingly. The Chief Engineer shall provide Central Basin with 30 days' notice regarding the decrease in allotment.”

The amended Section 6.3B adds language to the existing, in bold, that reads in its entirety as follows:

“6.3. Adjustments to Allotment. The District may adjust Central Basin' s allotment as

follows:

(21)

B. Decreases. If the Chief Engineer determines that Central Basin voluntarily, or without sufficient cause, failed to draw or beneficially use all or any part of its allotment for a consecutive 5-year period of time, then Central Basin will forfeit its right to the average of the unused portion, and Chief Engineer will reduce Central Basin' s allotment accordingly. The Chief Engineer shall provide Central Basin with

30 days' notice regarding the decrease in allotment. The provisions contained in

the previous two sentences will not be effective during the period of July 1, 2019 and June 30, 2021 (“Suspension Period”, as potentially extended below), and the allotment of recycled water to or the use of recycled water by Central Basin during the Suspension Period will not be used to calculate future decreases in Central Basin’s allotment. The Parties may, by written agreement executed no later than May 15, 2021, agree to extend the Suspension Period to and including the Fiscal Year ended June 30, 2022.

STATUS OF THE SANITATION DISTRICTS OF LOS ANGELES COUNTY WASTEWATER CHANGE PETITION WW0106 PURSUANT TO

CALIFORNIA WATER CODE SECTION 1211 SUMMARY:

In May of 2018, District staff began to meet with the Los Angeles County Sanitation Districts (LACSD) on a regular basis regarding the impacts of California Water Code Sections 1210 and 1211 (State law). In May, LACSD informed District staff that they had been facing challenges with supplying recycled water for new projects and site connections due to habitat downstream of the San Gabriel River. LACSD went on to state the main concern is due to the Least Bell’s Vireo and related habitat vegetation. Temporary recycled water supply restrictions were put in place by LACSD for San Jose Creek and Los Coyotes Reclamation Plants, along with new procedures for expanding recycled water use.

District staff and LACSD have been working together over the last two years to address customer connections and projects that were waiting on, or working towards, connecting to the District’s recycled water system. In an effort to help the District, LACSD was able to generate a “new” supply of recycled water (approximately 896 acre-feet per year) at the Los Coyotes Water Reclamation Plant by reducing the frequency of backwashing their filters. That way they are not reducing discharges to the river by allowing the District to use the volume of water no longer used in the backwashing process. This new supply has enabled the District to expand recycled water use over two years while LACSD works to satisfy State law requirements.

State law requires the owner of a wastewater treatment plant to file a wastewater change petition with the Division of Water Rights. To approve a wastewater change petition, the State Water Resources Control Board must be able to find that the proposed change (reducing discharges to the river) will not injure other legal users of water, will not unreasonably harm instream uses (habitat), and is not contrary to the public interest. The California Environmental Quality Act (CEQA) applies to non-exempt wastewater change petitions. The petition process flow chart is attached to this memo as Exhibit “A.”

In 2019, LACSD submitted an Initial Study, Mitigated Negative Declaration, Adaptive Management Plan, and an Environmental Impact Report to fulfill CEQA requirements. Due to the expansive nature of these documents, these reports can be accessed at the link below.

DIVISION OF WATER RIGHTS

In the Matter of Wastewater Petition WW0106

Sanitation Districts of Los Angeles County

ORDER APPROVING CHANGE IN PLACE OF USE,

PURPOSE OF USE, AND QUANTITY OF DISCHARGE

SOURCE: San Gabriel River

COUNTY: Los Angeles

WHEREAS:

1. On June 14, 2019, the Sanitation Districts of Los Angeles County (Sanitation Districts) filed Wastewater Change Petition WW0106 with the State Water

Resources Control Board (State Water Board), Division of Water Rights (Division), pursuant to Water Code section 1211. The petition seeks to change the place of use, purpose of use, and quantity of treated wastewater currently discharged to the San Gabriel River.

2. Water Code section 1211 requires the owner of a wastewater treatment plant to obtain approval from the State Water Board prior to making any change in the point of discharge, place of use, or purpose of use of treated wastewater where changes in the discharge or use of treated wastewater result in decreasing the flow in any portion of a watercourse.

3. The Sanitation Districts’ Los Coyotes Water Reclamation Plant (LCWRP) is a

wastewater treatment facility in the City of Cerritos. The LCWRP generates

approximately 20.6 million gallons per day (MGD) (5-water-year average from 2014 through 2018 of discharge volumes) of tertiary-treated effluent, of which about 17 MGD is discharged to a concrete-lined portion of the San Gabriel River. The LCWRP has one discharge point: LC001 which discharges to the San Gabriel River.

4. Reclamation of treated wastewater from the LCWRP for non-potable purposes is currently authorized by the Los Angeles Regional Water Quality Control Board (Los Angeles Regional Water Board) under Order. No. 87-51 and readopted under Order No. 97-072.

(26)

Wastewater Petition WW0106 Page 2 of 5

5. Discharge of treated wastewater from the LCWRP to the San Gabriel River is currently authorized by the Los Angeles Regional Water Board under Order No. R4-2015-0124, NPDES Permit No. CA0054011.

6. The Sanitation Districts’ existing point of discharge, place of use, and purpose of use of treated wastewater is as follows:

a. The point of discharge is the following: Los Coyotes Water Reclamation Plant discharge point at California Coordinate System, NAD 83, Zone 5:

1) Discharge Point LC001: Northing 1,778,709.91469 and Easting 6,528,807.05578, PLSS, Rancho Los Coyotes;

b. There is no current place of use; and, c. There is no current purpose of use.

7. The Sanitation Districts propose to reduce LCWRP discharge at Discharge Point LC001 from approximately 17.0 MGD down to a minimum monthly average of 2.0 MGD. This reduced flow would be directed to the landscape irrigation of parks, schools, golf courses, greenbelts, etc., and industrial use by local manufacturers. 8. On October 15, 2019, the Division issued a public notice of the petition in

accordance with Water Code section 1703. No protests were received.

9. Under the California Environmental Quality Act (CEQA), the Sanitation Districts are the lead agency for preparation of environmental documentation for this project. In 2019, the Sanitation Districts issued a Notice of Preparation and Initial Study for an Environmental Impact Report (EIR) and released a Draft EIR in August 2019. A Final EIR was certified and a Notice of Determination (NOD) was issued in November 2019. The State Water Board is a CEQA responsible agency for

purposes of considering whether to approve the petition that will allow the Sanitation Districts to proceed with the proposed project. As a CEQA responsible agency, the State Water Board must consider the environmental documentation prepared by the lead agency and any other relevant evidence in the record and must reach its own conclusions on whether and how to approve the project involved. (Cal. Code Regs., tit. 14, § 15096, subd. (a).)

10. The State Water Board has considered the Final EIR in deciding whether to approve the petition. The Final EIR considers the potential impacts of reduced flows to the San Gabriel River Watershed. The flow impacts are evaluated in the Final EIR, which determined that there will be no significant impact to fish, wildlife, or the

environment. The State Water Board will issue a NOD within five days of the date of this Order.

(27)

11. The State Water Board has reviewed the petition and the entire administrative

record, including CEQA documents associated with the proposed project. The State Water Board finds that the changes proposed in the petition will not cause injury to any other lawful user of the water.

12. In addition to the State Water Board’s obligations under CEQA, the State Water Board has an independent obligation to consider the effect of the change on public trust resources and to protect those resources where feasible, and to balance any

adverse public trust effects against the benefits of the project. (National Audubon

Society v. Superior Court (1983) 33 Cal.3d 419 [189 Cal.Rptr. 346].) Based on the State Water Board’s review of all relevant evidence in the administrative record, no adverse impacts to public trust resources, including fish and wildlife, are expected as a result of the proposed project.

13. The State Water Board has a Policy for Water Quality Control for Recycled Water (Recycled Water Policy), originally adopted on February 23, 2009 and amended on January 22, 2013 and December 11, 2018. The purpose of the Recycled Water Policy is to increase the use of recycled water from municipal wastewater sources, and one of the goals for California is to increase the use of recycled water over 2002 levels by at least one million acre-feet per year by 2020, and by at least two million acre-feet per year by 2030. The Sanitation Districts’ project, as proposed in the petition, is consistent with the purpose of the Recycled Water Policy and will help California meet the goals of the Recycled Water Policy.

14. Pursuant to Resolution 2012-0029, the State Water Board has delegated the

authority to administer the State Water Board’s water rights program to the Deputy Director for the Division of Water Rights. The Deputy Director for the Division of Water Rights has redelegated that authority.

ORDER NOW, THEREFORE, IT IS ORDERED THAT:

1. The point of discharge is unchanged and is located as follows. The Los Coyotes Water Reclamation Plant (LCWRP) discharge point at California Coordinate System, NAD 83, Zone 5: 1) Discharge Point LC001: Northing 1,778,709.91469 and Easting 6,528,807.05578, PLSS, Rancho Los Coyotes.

2. The request to change the place of use is approved. The place of use for treated wastewater produced by the LCWRP is within the Central Basin Municipal Water District, City of Signal Hill, City of Lakewood, and Water Replenishment District of Southern California, as shown in Figure 1 filed with the petition.

(28)

3. The request to change the purpose of use is approved. The purposes of use for treated wastewater produced by the LCWRP are Municipal, Industrial, and Irrigation.

4. The quantity of discharge of treated wastewater from the LCWRP to the San Gabriel River may be reduced from 17.0 million gallons per day (MGD) down to a monthly average of 2.0 MGD, from January 1 to December 31 of each year. 5. Prior to operation of the project, the Sanitation Districts of Los Angeles County

(Sanitation Districts) shall obtain any and all necessary federal (including Clean Water Act section 404), state and local agency permits and approvals required for implementation of the project. Copies of such permits and approvals shall be forwarded to the Deputy Director for the Division of Water Rights.

6. The Sanitation Districts are responsible for compliance with any applicable waste discharge or water recycling requirements issued by the Los Angeles Regional Water Board or the State Water Board.

7. The State Water Board reserves jurisdiction in the public interest to implement and amend this Order for conformity with instream flow requirements that may be established for the San Gabriel River in the future, and in the event of unforeseen adverse impacts to fish and wildlife resources and other instream beneficial uses. Modifications to this Order shall only be made after notice and opportunity for a hearing.

8. The Sanitation Districts shall file an annual report with the Deputy Director for the Division of Water Rights by March 31 of each year following the year of order issuance that includes at minimum the following information for the previous calendar year:

• monthly amount of inflow to the LCWRP;

• daily discharge rate to the San Gabriel River in MGD;

• daily recycled water delivery rate in MGD; and,

• monthly total recycled water deliveries.

If identical information is already reported annually to the Regional Board or State Water Board under the requirements of the Recycled Water Policy, the Sanitation Districts may annually notify the Deputy Director for the Division of Water Rights of the submittal and where the information may be found in lieu of filing a redundant annual report under this term.

ACTION CALENDAR

APPROVAL OF AMENDMENT NO.1 TO CONTRACT AGREEMENT 2015-35 FOR PURCHASE AND SALE OF RECYCLED WATER FROM THE SANITATION

DISTRICTS OF LOS ANGELES COUNTY SUMMARY:

Historical Background

In 1991, Central Basin entered into a 25-year agreement with the Sanitation Districts of Los Angeles County (LACSD) to purchase recycled water from the Los Coyotes Reclamation Plant (LCRP) for the Century Recycled Water Project. This agreement allowed for the purchase of up to 8,000 acre-feet per year (AFY). Likewise, in 1992, the District also entered into a separate 25-year agreement to purchase water from the San Jose Creek Plant (SJCP) which would feed the Rio Hondo Distribution system. This agreement allowed for up 15,000 AFY for a total of 23,000 AFY between the two agreements. These original contracts were scheduled to expire on January 22, 2016 and August 31, 2017, respectively.

The Board approved an extension in February 2015 as described below. Prior to the original contracts expiring, towards the end of the 2014 calendar year, staff began negotiations with LACSD staff for a new merged 25-year agreement to ensure the viability of the recycled water program into the foreseeable future. Negotiations were extended to try to reach an agreement on a sufficient amount of minimum recycled water allotted to Central Basin annually. The original agreements allowed for up to 23,000 AFY but Central Basin had never used more than 6,000 AF in any given year at that time. Furthermore, competition for recycled water supplies has increased dramatically in the last 10 years. Lastly, available outflow from the plants has significantly diminished over the last 10 years due to conservation efforts. Consequently, LACSD cannot commit to give excess water to Central Basin when we have not demonstrated we can put it to immediate use.

Central Basin and LACSD staff were able to come to agreement on terms for the purchase contract that would allow for expansion for Central Basin but not overcommit the scarcest supplies of recycled water from LACSD. The following represent the existing contract’s major terms that were approved by the Board in February of 2015:

1. The two preexisting contracts are rolled into one purchase agreement; 2. Maximum water available is reduced from 23,000 AFY to 10,500 AFY;

a. No more than 6,000 AFY can be pulled from the SJCP; b. Remainder must pulled from LCRP;

c. Additional water can be granted in the future if Central Basin proves demand and supply is available;

d. Available water can be reduced if not used within five years;

EXHIBIT "B"

(31)

CBMWD Board Memorandum January 27, 2020

3. The term is 25 years from effective (approval) date;

4. Minimum price transitions from 20% of LACSD O&M costs to 30% to be on par with other LACSD contracts;

a. Transition time-minimum price increases 2% per year for years until at 30%. A copy of the entexisting contract inclusive of the above terms and conditions is attached as Exhibit “A”.

Current Contractual Issue

This contract agreement is financial in nature as a purchase agreement; however, there are operational aspects of this agreement that have come into the spotlight that need to be addressed.

The current temporary supply restriction directly challenges the term in 2(d) listed above.

Amendment to Contract

Central Basin staff has been working with LACSD to prepare an amendment to our current agreement which will postpone supply reductions during the period of July 1, 2019 through June 30, 2021 (the “Suspension Period”), with the opportunity to extend the Suspension Period through the Fiscal Year ending June 30, 2022. This was done with consideration of the current supply restrictions that prevent Central Basin from expanding the use of recycled water and to

avoid reductions in supply allotments. The amendment has been reviewed by Central Basin’s

current Interim Legal Counsel and is attached to this memo as Exhibit “B”. Section 6.3B, in the existing agreement, currently reads as follows:

“6.3. Adjustments to Allotment. The District may adjust Central Basin' s allotment as follows: B. Decreases. If the Chief Engineer determines that Central Basin voluntarily, or without sufficient cause, failed to draw or beneficially use all or any part of its allotment for a consecutive 5-year period of time, then Central Basin will forfeit its right to the average of the unused portion, and Chief Engineer will reduce Central Basin' s allotment accordingly. The Chief Engineer shall provide Central Basin with 30 days' notice regarding the decrease in allotment.”

(32)

CBMWD Board Memorandum January 27, 2020

The amended Section 6.3B adds language to the existing, in bold, that reads in its entirety as follows:

“6.3. Adjustments to Allotment. The District may adjust Central Basin' s allotment as follows:

B. Decreases. If the Chief Engineer determines that Central Basin voluntarily, or without sufficient cause, failed to draw or beneficially use all or any part of its allotment for a consecutive 5-year period of time, then Central Basin will forfeit its right to the average of the unused portion, and Chief Engineer will reduce Central Basin' s allotment accordingly. The Chief Engineer shall provide Central Basin with 30 days' notice regarding the decrease in allotment. The provisions contained in the previous two

sentences will not be effective during the period of July 1, 2019 and June 30, 2021 (“Suspension Period”, as potentially extended below), and the allotment of recycled water to or the use of recycled water by Central Basin during the Suspension Period will not be used to calculate future decreases in Central Basin’s allotment. The Parties may, by written agreement executed no later than May 15, 2021, agree to extend the Suspension Period to and including the Fiscal Year ended June 30, 2022.

PROCUREMENT PROCESS: Not applicable.

FISCAL IMPACTS:

While this amendment has no quantifiable financial impact, it will benefit Central Basin in preserving its allocation of recycled water from LACSD.

COMMITTEE STATUS:

This item will be reviewed by the Special Engineering & Operations Committee on January 15, 2020.

RECOMMENDED MOTION:

That the Board authorize the Interim General Manager to approve and execute the First Amendment to Contract Agreement 2015-35 for the Purchase and Sale of Recycled Water with District No. 2 of the Sanitation Districts of Los Angeles County.

SEPTEMBER 28, 2020 - Board Meeting Prepared by: Erin Maciel

Submitted by: Erin Maciel Approved By: Alex Rojas.

STATUS REPORT ON CONSTRUCTION OF THE MONTEBELLO BOULEVARD RECYCLED WATER PIPELINE SUMMARY:

This item is a status report on the Montebello Boulevard Recycled Water Pipeline. The 16-inch PVC pipeline is being constructed to serve the proposed Montebello Hills Specific Plan Project (Montebello Hills Housing Development Site) which is a 488-acre future residential living development of approximately 1,200 dwelling units to be located in the City of Montebello. The pipeline will extend from the District’s existing 30-inch pipeline within Lincoln Avenue and head north approximately 2,600 linear feet within Montebello Boulevard to the project area.

The total permanent irrigated area within the Montebello Hills development will use approximately 240 AF per year for a proposed park, landscaped slopes, recreation facilities, greenbelts and parkways. District staff obtained written approval of recycled water supply from the Sanitation Districts of Los Angeles County (LACSD) in December 2018. The developer’s mass grading operations to prepare the development sites will temporarily require more recycled water beyond the approved 240 AF per year. Staff has communicated the need for additional temporary grading water to LACSD.

Toll Brothers is constructing all pipelines and the permanent pump station on behalf of the District. West Yost, the pipeline and pump station designer is managing the construction for Toll Brothers and the District. Only the 16-inch supply pipeline is being constructed at this time. The District has brought on Tetra Tech via their on-call Engineering Contract to conduct construction inspection for the pipeline construction.

Coordination with Montebello Boulevard Street Reconstruction

The City of Montebello is reconstructing Montebello Boulevard to accommodate the Montebello Hills development. To expedite the recycled water pipeline construction in order to install it before the street is completed, Toll Brothers is contracting directly with the city’s street contractor, Sequel Contractors, Inc., to construct the pipeline. Once the street work is completed, the city expects to impose a moratorium on any underground construction that would disturb the new asphalt. Staff has been working closely with the city to ensure all parties are kept informed of the status of the pipeline work. Construction of the District’s 16-inch Montebello Boulevard pipeline began in February 2020.

Pipeline Use During Grading Operations

The northern end of the 16-inch Montebello Boulevard pipeline will terminate just inside the development site, adjacent to the future booster pump station to be constructed in the future by Toll Brothers. Toll Brothers will use the newly constructed pipeline for onsite recycled water for

(38)

grading in Spring 2020. District staff has worked with Toll Brothers and the Los Angeles County Department of Public Health to obtain approval for onsite use of recycled water for construction purposes. The Los Angeles County Department of Public Health has received all of the necessary documentation for regulatory approval, and are currently waiting for Toll Brothers to finish the pipeline project in order to conduct a final inspection and formal approval for the site to use recycled water for grading

Construction Progress

March 2020 Update:In early February 2020, Central Basin staff had a pre-construction meeting with Toll Brothers, Tetra Tech, and the City of Montebello and the contractor, Sequel.

Trenches are being dug for the 16” Pipeline in Montebello Boulevard and pipe is being put in the ground. Construction has been proceeding smoothly with minor field changes that are being handled by the contractor, design engineer and District staff. Central Basin staff is in the process of reviewing the final plans from West Yost for the backbone pipeline, as well as the initial plans for the pump station.

April 2020 Update: There were several days of rainy weather where construction was not able to occur since the last update. On March 25, a pipeline that belongs to the City of Montebello was damaged by the contractor. As a result, a large leak occurred and has slowed construction of the project. The contractor is currently determining the permitting process for discharging the water into the sewer.

May 2020 Update:Central Basin staff spoke to its construction inspector and was informed that approximately 200 ft. of pipe was laid the last week of April, and the contractor was reaching the end of the pipeline. Unfortunately, the contractor ran into several utilities including a storm drain, and is currently working with West Yost, Central Basin, and Toll Brothers to decide how to circumvent this storm drain while sill staying in compliance with the State Water Resources Control Board regulations.

June 2020 Update: Staff received the update that the last section of pipeline has been

constructed, and the only item left remaining before the pipeline is complete, is a blow off valve that needs to be installed at the end of the 16” water main. The pipeline was pressure tested on 6/11/2020 to validate pipeline integrity.

July 2020 Update:At the time this memo was due, the only item left remaining before the pipeline is complete, continues to be a blow off valve that needs to be installed at the end of the 16” water main. Staff have continued to work with the State Water Resources Control Board for approval of changes to project construction. The State Water Resources Control Board has received plan revisions for all changes to date. Formal project approval and recording of project completion is anticipated to happen this month.

August 2020 Update: The pipeline has been completed. Staff is ready to supply recycled water via the new pipeline at Toll’s request.

(39)

PROCUREMENT PROCESS:

On January 23, 2017, the Board approved an agreement with Tetra Tech to provide “On-Call as Needed Engineering Design and Technical Services" for various recycled water projects for an amount not-to-exceed $150,000, following a competitive proposal process using District RFP No. 165. In June 2019, the term of that agreement was extended from June 30, 2019, to June 30, 2020, following District policy and procedures.

The District is providing inspection of the pipeline to ensure it is constructed according to the project plans and specifications and that it meets District standards. Inspection services are being provided by Tetra Tech, a professional engineering firm, which provides on-call services, like inspection, to augment District staff.

Tetra Tech has assigned one of its staff inspectors to inspect the Montebello pipeline project during construction.

No additional procurement of services to support the pipeline construction is anticipated at this time.

FISCAL IMPACTS:

Design, partial environmental compliance, and construction of this project is funded by Toll Brothers.

Considering assumptions per recent discussions with Toll Brothers, the potential gross revenue to be generated via recycled water sales (240 AFY-446 AFY) is estimated to be approximately $174,960 - $325,134 per year based on the current recycled water rate.

These numbers place the payback period for the District within the first year when only considering the permanent irrigation supply of 240 AFY based on costs in Table 1. Increasing deliveries temporarily to 446 AFY will shorten the payback even more.
