9 (CITY ATTY: 05-19)
under this Agreement and since there is no direct legal authority for this position, the City is not requiring Consultant to provide a payment bond at this time. However, the City hereby reserves the right to require the Consultant to obtain and provide a payment bond for some or all of the Services provided by the Consultant under this Agreement.

If the City determines that a payment bond is required for the Services pursuant to Civil Code Section 9550 or any other applicable law, rule or regulation, Consultant shall execute and provide to City a payment bond in an amount required by the City and in a form provided or approved by the City. In the event a payment bond is required, the City agrees to compensate Consultant for all documented direct costs incurred by Consultant for such payment bond. The Parties shall memorialize the terms of such additional compensation and any other terms and conditions associated with the payment bond in an amendment to this Agreement.

3.2.13 Accounting Records. Consultant shall maintain complete and accurate records with respect to all costs and expenses incurred under this Agreement.

Beginning April 1, 2015, no consultant or subconsultant may be awarded this Agreement unless registered with the DIR pursuant to Labor Code Section 1725.5.

Consultant shall make copies of the prevailing rates of per diem wages for each craft, classification or type of worker needed to execute the Services available to interested parties upon request, and shall post copies at the Consultant’s principal place of business and at the Project site. It is most efficient for the Consultant to obtain a copy of the prevailing wages in effect at the commencement of this Agreement from the website of the Division of Labor Statistics and Research of the DIR located at www.dir.ca.gov/dlsr/. In the alternative, Consultant may obtain a copy of the prevailing wages from the City’s Representative. Consultant shall defend, indemnify and hold the City, its elected officials, officers, employees and agents free and harmless from any claim or liability arising out of any failure or alleged failure to comply with the Prevailing Wage Laws.

3.3.6 Apprenticeable Crafts.

SCOPE OF SERVICES

PLANT DESCRIPTION
The City Utilities Department operates three water reclamation facilities (WRFs); WRF No. 1, WRF No. 2, and WRF No. 3. WRF No. 2, located at 650 E. Harrison Street, Corona, CA was formerly the Sunkist Treatment Plant, which was used to treat industrial process wastewater.

In 1986, the City purchased this treatment plant and upgraded it by 1988 to provide a primary and secondary permitted treatment capacity of 3.0 MGD. In 2014, Utilities Department upgraded the treatment process to provide full tertiary treatment to its permitted 3.0 MGD design capacity. WRF No. 2 currently operates under and complies with the California Regional Water Quality Control Board, Santa Ana Region, Waste Discharge Requirements Order No. R8-2007-0052.

WRF No. 2 is located within a mixed commercial and industrial zone (with residential housing and apartments located approximately 2,000-3,000 feet away). The following are the key processes at WRF No. 2:
• Intermediate Pump Station (for lifting plant influent to headworks) • Headworks
• Aerated Grit Basins (2)
• Primary Clarifiers (2)
• Equalization (EQ) Ponds (2)
• Activated Sludge Basins (2)
• Secondary Clarifiers (3)
• Tertiary Filtration
• Chlorine Contact Tanks
To optimize operation and minimize odors, five desired improvements have recently been identified.

1. Upsizing the flow equalization basin to 1 million gallons to allow the plant to function at its permitted capacity.

2. Adding a pump station taking suction from the flow equalization outlet to pace flow to the aeration basins/activated sludge basins.

3. Modifying the existing mechanical aeration in the activated sludge basins to fine bubble aeration to replicate facilities at other plants.

4. Covering open aerated grit basins, primary clarifiers, and flow equalization to contain odors.

5. Providing odor control and treatment (biofilter) facilities to allow air in covered processes to be released without odor complaints.

Studies on how to implement these objectives are included in the appendices:

• Immediate and future odor control goals are presented in the Odor Control Study prepared by Jacobs/CH2M Hill in November 3018.
• In June 2020, NMG Geotechnical, Inc. performed a geotechnical exploration for the proposed equalization basin replacement.
• In June 2022, a design-build package was advertised that incorporated four of the five desired improvements listed above (excluding the aeration changes). The design-build project was not awarded because only one bid was received, and it was much higher than expected. Subsequently it was decided to proceed with a traditional design-bidbuild delivery method and add the aeration changes to allow all remaining work at WRF No. 2 to be addressed under one contract.
• A study of design alternatives for aeration at WRF No. 1 was prepared by HDR in 2017. The study recommended installing EDI tube diffusers in the activated sludge basins at WRF No. 1 as the most economic method of air transfer.

PROPOSED IMPROVEMENTS
The City desires to construct new flow equalization, aeration, pumping, odor control, and piping facilities at WRF No. 2 to enable the City to expand treatment capability to the current 3.0 MGD permit capacity and address recurring odor complaints downwind from the facility. The City is currently operating WRF No. 2 at 2.3 MGD and desires to operate at its permit capacity of 3.0 MGD.

The Project will consist of the following:

1. Prepare demolition plans to decommission and demolish the following:
a. Existing flow equalization (EQ) basins No. 1 and No. 2. b. Existing screw pump lift station to be replaced with Vaughn chopper pumps. c. Existing mechanical mixers (6) in aeration tanks No. 1 and No. 2.

2. The existing flow EQ basins’ limited Record-Drawing volume of 651,485 gallons limits the practical treatment capacity of plant processes downstream. The new flow EQ basins will need to be designed with a volume of 1,000,000 gallons.

3. Design a new coarse bubble aeration system to mix and freshen the wastewater in the new flow EQ basins.

4. Design improvements to replace the existing screw pump station downstream from the flow EQ basins with a Vaughn chopper centrifugal pump configuration that is easier to control and simplifies pacing of EQ basin flow to the aeration basins.

Decommission and demolish existing screw pump station.

5. Design a second new fine bubble aeration system (EDI tube diffusers) to mix and aerate the wastewater in Aeration Tank No. 1 and No. 2.

6. Design three new blower stations for:

20 (CITY ATTY: 05-19)
a. Aeration to freshen flow equalization basin
b. Aeration to activated sludge tanks
c. Foul air turnover and odor control in covered basins

7. Retrofit existing aeration basin influent box and effluent box to allow flows in and out of Aeration Tank No. 2.

8. Design aluminum covers for odor control over the grit chamber, primary clarifiers, and new flow EQ basins.

9. Design an odor control biofilter system to treat air ventilated from covered areas to a biofilter system.

10. Design all new facilities with safe access for inspection and cleaning.

11. Design sitework, including concrete, grading, paving, piping, and miscellaneous site improvements, as needed.

12. Design modifications to existing facilities, as needed.

13. Design all electrical infrastructure, including conduits, pull boxes, wiring, grounding, and enclosures; variable frequency drive (VFD) units and on-site electrical infrastructure; surveying; geotechnical engineering; permitting and regulatory approvals including AQMD compliance.

14. SCADA programming and system integration to be coordinated with South Coast Automation Systems, Inc., the City’s SCADA programming vendor.
