10300 Torre Avenue, Cupertino, California 95014 (408) 777-3308
To:
Mayor and City Councilmembers
Chairman and Planning Commissioners
Steve Piasecki, Director of Community Developme~
From:
Date: March 14, 2002
Application No.: DIR-2001-24
Subject: Report of Director's Decision Regarding a Minor Modification for
installation of storage tanks for ch1oramination of the California Water
Service well.
Chapter 19.132 of the Cupertino Municipal Code allows for administrative approval of
minor changes in a project. The Director reports his decision to the City Council and
Planning Commission in time to allow any Councilmember or Planning
Commissioner to appeal the decision within fourteen calendar days.
Action Taken
The Director approves the modification. This approval is effective March 25,2002. The
fourteen calendar day appeal period will expire on April 8, 2002.
Background
Local municipalities and water companies have been mandated by the Environmental
Protection Agency (EPA) to eliminate or reduce Trihalomethanes (THMs) from public
water supplies to 0.1 part per million (100 parts per billion). Trihalomethanes are
produced when chlorine interacts with organic material in water, such as dead leaves or
sediment. THMs have been classified by the EP A as probable or possible human
carcinogens, associated with certain cancers. Chloramination is the use of chlorine
mixed with ammonia, which reduces the possibility of THMs. Many of the water
supply sites in Santa Clara County have already switched from chlorination to
chloramination.
Discussion
The subject site is the California Water Service Los Altos Suburban Station 34-01,
located at the north end of Portal Avenue adjacent to Interstate 280.
The applicant proposes to construct two 64 square foot buildings at the existing Los
Altos Suburban Station 34-01 at North Portal. Each building will contain one storage
tank. One building will contain a Sodium Hypochlorite (NaGCl) tank, which is the
chemical used to add chlorine to swimming pools and is a standard ingredient in
bleaching solutions and water purifiers. The second building will contain an
Ammonium Hydroxide (NH40H) tank, which is basically ammonia dissolved in water
at high concentrations. Ammonium Hydroxide is widely used as a household cleaner.
The combination of the two tank's contents will create chloramines.
The two buildings will be setback more than 35 feet from neighboring single family
residential property lines. One building will require an air conditioning unit for
cooling. The manufacturer's documentation for the air conditioning unit chosen by the
applicant claims the unit is "ultra-quiet./I The exterior mounted unit is similar to those
added on to residential structures.
The project has been reviewed and approved by the County Fire Department, who will
inspect the site before it becomes operational.
The subject site is also the location of a future monopole by MetroPCS. The applicant
has verified that the chloramination project will not interfere with the MetroPCS
monopole project.
