DATE: January 26, 2004
TO: Honorable Mayor and City Council
THRU: John B. Bahorski, City Manager
FROM: Douglas A. Dancs, Director of Public Works /City Engineer
SUBJECT: RECEIVE AND FILE: SPECIFICATIONS FOR A WASH
RACK
SUMMARY OF REQUEST:
Receive and File.
BACKGROUND:
The Clean Water Act (officially known as the Federal Water Pollution Control Act
Amendments of 1972) was passed into law to restore and maintain the chemical, physical,
and biological integrity of the Nation's waters, and where attainable, to achieve a level of
water quality that provides for the protection and propagation of fish, shellfish, and wildlife,
and for public recreation in and on the water. The first goals of the Clean Water Act are
zero discharge of pollutants and the protection of "fishable /swimmable" water quality.
Since 1993, the City has been a co- permittee with the County of Orange to meet the
requirements of the various regulations associated with the Act. After each permit renewal,
the City is required to continue to implement storm water quality management programs
and develop additional programs in order to control pollutants in storm water discharges.
On January 18, 2002, the SARWQCB adopted Order No.R- 2002 -001 entitled "Waste
Discharge Requirements for the County of Orange, Orange County Flood Control District,
and the Incorporated Cities of Orange County within the Santa Ana Region Area Urban
Storm Water Runoff Orange County" known as "the Permit ".
As part of the permit, the City must make certain that none of its facilities are in violation
of the permit requirements. The City's Maintenance Yard ( "Yard ") is treated as an
industrial facility within the permit and all wash water from vehicles or equipment must
be collected and properly disposed. The Yard's current wash rack system is in need of
replacement and major upgrade. The Department investigated various options and
determined it would be more cost effective to purchase an "off the shelf' unit. The system
would need to accommodate large vehicles and equipment of the Department.
Additionally, the specifications require that the unit be movable, pre -filter and treat wash
water collected in the system so that it is acceptable for discharge into the sewer as well
Agenda Item P
as mud and oil separator filtering systems. The water used would also be recycled and aid
in the City's water conservation efforts.
After request for proposal is circulated, a contract for purchase will be brought forward in
the spring. The system is expected to cost $70,000 and funds are available within the
Council approved Capital Improvement Program specifically for storm water quality
upgrades to the Maintenance Yard for compliance with the permit.
FISCAL IMPACT:
Funding is available within the Capital Improvement Program.
RECOMMENDATION:
Receive and File.
