RELATING TO THE BASIS FOR BILLING, THE PROCEDURES
FOR BILLING, AND THE PAYMENT FOR EXPANDED TREATMENT
CAPACITY AT THE REGIONAL WATER QUALITY CONTROL PLANT
WHEREAS, the Cities of Palo Alto, Mountain View, and Los Altos
have joined resources for the purpose of constructing a regional water
quality control plant, hereinafter called "Plant", said Plant bei'ng
owned and operated by the City of Palo Alto; and
WHEREAS, Plant is used to process sewage effluent of the Town of
Los Altos Hills in accord with a contract, Palo Alto No. 2876, dated
March 18, 1968, and amended from time to time including amendments,
addendums, and agreements of various dates; and
WHEREAS, the parties hereto desire to provide a different basis
for billina which considers not only the volume of wastewater discharge
for the plant from Los Altos Hills but also the strength of such
discharge, and to provide for the participation of the Town of Los
Altos Hills in the 1988.treatment plant capacity expansion;
NOW, THEREFORE, THE PARTIES hereto agree as follows:
1. Capacity of plant; use of capacity. The various units of the
Joint System shall be designed and have a capacity to convey to the
treatment plant, and treat and dispose of the volume of sewage specified
in exhibit "H" attached hereto and incorporated herein by this refer-
ence, and more particularly described in the "City of Palo Alto Water
Quality Control Plant Capacity Study May 1983 updated March 8, 198411 by
WWI. Los Altos Hills agrees to adjust existing capacity rights to a
uniform right capacity throughout all facilities of the plant as shown
in accordance with such exhibit "H".
2. Amendment of Exhibits. Exhibit "B" of the Agreement is of
hereby amended to, include the proposed plant enlargement and capacity
rights adjustments. Said amended exhibit is attached hereto and by
this reference incorporated herein as amended exhibit "B".
3. Acquisition and Construction Costs. Los Altos Hills shall
proceed to finance and pay for the plant enlargement in. the proportions
shown in exhibit "H". The Town of Los Altos Hills may participate in
the revenue bond issue with the City of Palo Alto up to the entire cost
of its share of the plant expansion, provided that Los Altos Hills de-
livers to Palo Alto a written agreement to pay for that capacity in in-
stallments of principal and interest equal to Los Altos Hills' propor-
tionate share of plant capacity as applied to Palo Alto's share of
principal and interest due and payable. Los Altos Hills, upon its
election prior to April 1, 1986, to participate in Palo Alto's bond is-
sue, hereby agrees to set rates at a level sufficient to recover net
revenues in an amount equal to it's share of Palo Alto's billing.
4. Until July 1, 1988, or the date of completion and operation
of the proposed plant expansion, whichever occurs later, either party
to this agreement whose total average dry weather flow to the regional
Water Quality Control Plant in any year exceeds the capacity rights of
such party shown in exhibit "n" shall be allowed to rent unused
capacity of the plant at a rate of four hundred dollars ($400) per MG
primary and secondary capacity and two hundred dollars ($200) per MG of
advanced waste treatment facility capacity. The unused capacity which
is available for rent under this paragraph shall be taken
proportionately from each party with unused capacity.
5. Los Altos Hills shall bear a proportion of the cost of
certain maintenance and operation expenses of the Joint System as those
maintenance and operation expenses are listed in exhibit "E" attached
hereto, and incorporated herein by this reference. Los Altos Hills'
portion of said costs shall be determined in proportion to its
contracted share of the City of Palo Alto's discharge rights in the
plant as shown in the "AAF" column of the 1995 design purchased
capacity column of exhibit "H", attached hereto and incorporated herein
by this reference. All other maintenance and operation expenses of the
Joint System shall be born by the parties in proportion to the
treatment costs associated with the volume of sewage, and the quantity
of chemical oxygen demand, suspended solids, and amonia contained
therein that each party contributes to the Joint System. For the
current fiscal year, such maintenance and operation expenses shall be
allocated in accordance with the percentages shown in exhibit "J",
attached hereto and incorporated herein by this reference, and adjusted
in subsequent years as provided therein.
6. Effect on Original Agreement. In all other respects, Contract
No. 2876, dated March 18, 1968, and as amended, shall remain unchanged

Allocation, billing, and payment of Palo Alto Regional Water
Quality Control Plant operation and maintenance expenses.
Operation and maintenance expenses shall be allocated to the
below -listed expense categories in the proportions shown:
Expense Category
Volume of sewage
Chemical oxygen demand (COD)
Suspended solids (SS)
Ammonia (NH3)
Proportion
34%
22%
22%
22%
In subsequent years, the above percentage allocations may be altered
based upon actual cost data derived in accordance with generally ac-
cepted accounting principles and upon agreement of all parties hereto.
The volume of sewage received and the concentration of chemical oxygen
demand, suspended solids, and ammonia contained therein shall be deter-
mined for each agency in accordance with the criteria set forth in this
Exhibit.
Treatment expense rates per million gallons of wastewater volume
and per thousand pounds of each of the other expense categories above
shall be established for each fiscal year. Each Agency shall pay its
portion of the operation and maintenance expenses based on these rates
and the volume and quality of its wastewater.
EVALUATING EXPENSE CATEGORY ITEMS
Waste. Water Volume
The wastewater volume for each Agency shall be measured by a flow
meter or flow meters in its outfall or outfalls or such other method as
agreed upon between parties. Sewage meters and their locations shall
be as approved by the Manager of the Treatment Plant.
Sewage Quality
The characteristic values of COD, SS, and NH3 shall be deter-
mined by sampling and analyzing wastewater from each Agency's outfall
according to good laboratory and sampling practices. The best equip-
ment and techniques reasonably available to the Regional Water Quality
Control Plant personnel shall be utilized in determining these charac-
teristic values.
All samples shall be analyzed at the laboratory of the Regional
Water Quality Control Plant. If any party to the agreement disputes
the findings of the foregoing sampling program, the disputing party may
collect samples at the same monitoring points and submit them for anal-
ysis by a laboratory approved by the Manager of the Palo Alto Water
Quality Control Plant at its own expense. Any disagreement over the.
resulting findings may be arbitrated as provided in Section 8(d) of
Contract No. 2876.
