Program Background

The San Diego Pure Water San Diego Program Phase 1: North City Project will clean recycled water to produce 30 million gallons per day(mgd) of high-quality purified water, reducing the City' s dependence on imported water. The Pure Water San Diego Phase 1 program will provide nearly one-half of San Diego's water supply locally by 2035. The Pure Water Program will include a system of treatment facilities, pump stations, and pipelines to be constructed in multiple phases and will offer a cost-effective investment for San Diego's water demand.

The Project is funded by a loan through WIFIA and the State Water Resources Control Board under the California Water State Revolving Fund (CASRF) program. The Consolidated Appropriations Act of 2014 includes an "American Iron and Steel" (AIS) provision that requires recipients of CASRF assistance to use iron and steel products produced in the United States.

The Project is an important step toward securing a local, drought-resilient water supply for San Diegans for generations to come. Construction of major water infrastructure including pipelines, pump stations, and treatment facilities is taking place in the Morena, Bay Park, Clairemont, University City, Miramar, and Scripps Ranch communities.

The project includes the installation of approximately nineteen (19) pneumatically operated SST flow control globe valves in the Secondary Stage Bioreactor basins. The installation of such products is an integral part of the plant that will supply water to the residents of San Diego.

To Whom It May Concern,

Kiewit Infrastruc ture West Co. (Kiewit) is requesting a produc t-specific projec t waiver of AISprovisions be issued for Type V214 ½-inc h high pressure low flow globe control valves with threaded ends, cast 31 6 stainless steel body, trim No. 03, type 16 single ac ting pneumatic ac tuator with spring return action, Fieldvue DVC6200 electropneumatic valve positioner with neoprene diaphragm, and 67CFR Airset for the North City Water Reclamation Plant Expansion and NCPWF Influent Pump Station and Pipe line Projec t, Bid No . K-21-1861 -DBB-3 (the "Project"). In accordance with the United States Environmental Protection Agency (USEPA) memorandum, Implementation of American Iron and Steel provisions of P.L. 113-76, Consolidated Appropriations Ac t, 2014, the information required for a waiver to be processed is included below and in the attached documents.

Project Background

The Project will inc rease treatment capac ity of the North City Water Reclamation Plant from 30 mgd to an annual average flow of 52 mgd. As part of this project, there will be serval process modific ations whic h will be implemented throughout the entire plant. The major sc ope elements associated with the expansion include: construction of the new primary clarifiers, expansion and reconfiguration of the aeration basins and the secondary clarifiers to first and second stage bioreac tor basins, installation of four new sec ondary clarifiers, one new tertiary filter, Pure Water Facility influent pump stations and pipeline, equipment replacements, and other work (site work, yard piping, electrica l, and instrumentation work).

The Project owner is the City of San Diego. The Project is funded by a loan through the Clean Water State Revolving Loan Fund ( CWSRF). The Consolidated Appropriations Act of 2014 includes an "American Iron a nd Steel" (AIS) provision that requires recipients of CWSRF assistance to use iron and steel produc ts produced in the United States.

Request for Waiver for Non-AIS Component in the North City Water Reclamation Plant Expansion (Project Number 1036-104827)

To: Kiewit Infrastructure West Co. 10704 Shoemaker Ave. Santa Fe Springs, CA 90670 Attn: Peter Meckling

Project: North City Water Reclamation Plant Expansion

To: Whom it may concern; Santa Fe Winwater (SFWW) is the supplier responsible for the below listed products for this project.

Santa Fe Winwater is requesting a Non- AIS waiver for the products listed below required on the North City Water Reclamation Plant Expansion:

Spec.# Qty Size Product Description Non-AIS Mfg - Delivery

City of San

Baumann: 0.5" High pressure low flow cast stainless steel globe valve with 4-20 pneumatic actuator

In full Compliance with Specifications (Cast Body Valve, specified FIELDVUE

Diego 19 0.5"

Approved Materials List

pneumatic actuator, & Neoprene diaphragm.)

Delivery 10-14 Weeks from Approved Submittals.

Cost

SFWW has conducted a thorough online & materials network research exercise to identify possible domestic resources that produce the products to meet the project's technical provisions and with AIS certification.

The Design Engineer has listed one manufacturer with specific attributes of the listed manufacture's (Baumann's) product offering for the application. Th is is a 4-20ma pneumatically controlled industrial process valve, whereby very little US manufacturing currently occurs in this market segment.

The Design Engineer has specified that only a Cast Body version and the specific, Fieldvue Model DVC6200 Pneumatic actuation, with Neoprene diaphragm will meet the criteria for this application. There is an unlisted manufacturer who can provide a specification conflicted, machined bar stock valve, versus the specified cast stainless steel but cannot provide the listed actuator manufacturer. In addition, the offered actuator is a rolling diaphragm configuration and does not provide the engineered specified neoprene diaphragm material. The pneumatic actuator is listed with the V214 specification and not in a separate actuator specification section. As such, the specified valve and specified actuator are a single integrated specified unit. There is no viewed manufacturer meeting the specification other than the listed manufacturer. SFWW cannot take responsibility for an alternate manufacturers performance which deviates from the specification and where very defined control parameters are required.

Each Mfg listed below was contacted by SFWW personnel to request AIS product quotations. SFWW research included the following response data:

SFWW is unable to locate a valve and actuator which meets the Design Engineers specified

product without exceptions and of an unknown performance meeting the requirements of the

specifications. Please grant an availability-based project-specific waiver for these items.

Sincerely,

Sean Norvell
