The Conditions in this permit that regulate the Industrial Waste Sprayfield are imposed
pursuant to State law only and as part of the State Waste Discharge Permit Program
(Chapter 173-216 WAC).
A.
B.
General Requirements
The Permittee shall complete and submit, to the Department for approval, a
Sprayfield Engineering Report by July 1, 1999. The report shall comply with
all of the requirements as contained in Chapter 4, "Detailed Engineering
Report" of the Department's May 1993 publication, Guidelines for Preparation
of Engineering Reports for Industrial Wastewater Land Application Systems, as
amended. If the Permittee will continue to discharge, at any time, wastewater
or effluent from the main treatment plant to the Industrial Waste Sprayfield, the
Sprayfield Engineering Report shall also comply with all of the applicable
requirements of the Department's February 1993 publication, Water
Reclamation and Reuse Interim Standards, as amended.
The report shall also comply with the requirements of WAC 173-240-060,
Engineering Report, and be approved by the Department prior to any related
construction. All construction and/or operational changes required by the
Sprayfield Engineering Report shall be completed and operational, to the
Department's satisfaction, by July 1, 2001.

Industrial Waste (IW) Sprayfield Planned Improvements
OPENING
The Wastewater Division has completed two phases of a three part study
examining the continued use of the IW sprayfield within the context of
compliance with State regulations (WAC 173-200) for groundwater quality
and the Water Reclamation and Reuse Interim Standards (WRRIS) Chapter
90.46 RCW. The completed studies, with development costs and dates
submitted to Council, are outlined below:

Waste Suitability Study
DISCUSSION
The IW studies conclude that the sprayfield is a viable treatment option for
industrial waste treatment if certain "long term" improvements are
accomplished. Table "6" (see attachment) from the 1994 Sprayfield Suitability
Study outlines most of the "long term" improvements required. We believe
the single most effective improvement, which can have the biggest effect on
improving groundwater quality, is the fall storage of excess industrial
wastewater, (approx. 12 million gallons). Moreover, for this improvement to
be effective, Del Monte will have to install a significant waste treatment
process at their facility to remove suspended solids. Those improvements
should result in the following:
• adequately pretreated industrial wastewater which can be applied to the
sprayfield
Page 1
Council rpt IWS 2
May 1, 1995
• reduction of pollutants and impacts to groundwater quality
• improved aesthetic conditions in and around the sprayfield
• overall better managed and operated sprayfield
• reduced possibility of regulatory or citizen legal action
• achieve compliance with groundwater quality regulations
The majority of the improvements listed on Table "6" are major capital
undertakings which should only be initiated after a detailed engineering
report, and, subsequent to, Del Monte entering into a long term financial
agreement with the City of Yakima. An existing appropriation
(approximately $1,000,000) exists in the 478 Facilities Construction Fund for
necessary IW improvements. This fund anticipates a much larger capital
improvement program once those improvements are clearly identified in a
future Engineering Report.
Staff began to implement several operational changes and capital
improvements in 1994 (see Table 5). These improvements are part of annual
preventative maintenance/repairs and must occur regardless of other long
term improvements. Short term improvements are not expected to make
significant improvement in ground water quality or in keeping the City in
compliance with existing groundwater regulations. The short term
improvement costs were approved through the 1994 budgeting process and
recommended in the 1992 groundwater monitoring study. Recently
implemented changes include removing the cattle grazing operation from
the IW sprayfield and purchase of farm equipment to harvest forage from the
fields. This should result in less soil compaction and reduce the chance of
nitrate contamination to groundwater from cattle manure. This year we will
utilize the forage removed from the field to compost with biosolids. This
compost will be beneficial to the sprayfield when reapplied to the fields.
Currently the fields are extremely deficient in available topsoil and nutrients.
The other short term improvements identified in Table "5" will take place in
1995 to ensure continued sprayfield and pump station viability. Del Monte
and American Foods would continue to pay their share for these
improvements at the rate approved in the 1994 study as a part of the normal
cost of operation and maintenance. These costs and improvements will
continue to be clearly described and appropriated during the annual
budgeting process. Del Monte has written a limited letter of support for
recommendations and is enclosed for your review.
Del Monte initiated their proposed waste reduction and recycling efforts in
1994. However, very little improvement in wastewater quality was observed
from those efforts. On the contrary, we have experienced a dramatic shift
from one type of waste to another type -- suspended solids converted to
'issolved solids.

ACTION
Staff will proceed with distribution of the Suitability Study to the Department
of Ecology (DOE) and Del Monte for their review. DOE may conceivably
initiate a compliance order based upon the findings of the report which
identifies groundwater degradation during sprayfield operation. This
potential compliance order could stipulate one of the following scenarios
until such time that pretreatment and fall storage of the industrial wastewater
is accomplished:
•Cease all application of industrial wastewater to the sprayfield, thereby
requiring treatment through the domestic portion of the treatment facility.
•Divert a portion of the industrial wastewater through the facility during the
fall period when the sprayfield is overloaded.
Both of the above scenarios are not positive developments and will impact
facility capacity and/or process efficiency significantly.

Chris Waarvick, Wastewater Plant Superintendent
Subject: Industrial Waste Suitability Study
Wastewater staff have been studying the implications of
groundwater quality mandates (Ecology WAC -173-200) in relation to
the use of the Industrial Waste sprayfield. Correspondence and
Council action on this issue include the March 10, 1992 Council
authorization for a $75,000 groundwater monitoring study, March 4,
1993 study session on Industrial Waste sprayfield and groundwater
issues, and an August 6, 1993 authorization to start a $41,800
Industrial Waste Sprayfield Suitability Study. The draft results of
the Suitability Study are attached for your review.
Del Monte and American Foods have been kept closely appraised of
all activities and information relevant to these studies and reports.
Both of these companies are currently reviewing and commenting on
the implications of this study. In summary the study makes the
following recommendations:
• The groundwater beneath the sprayfield is adversely affected
(by Ecology standards) from the sprayfield operation. It still remains
a viable option for treating industrial waste but only if certain
actions are taken including: pretreatment of the incoming
wastewater, storage of the wastewater in the fall when conditions
require it, and increased operational management of required
sprayfield activities.
• Pretreatment of the incoming wastewater would be most
effective if it occurred at the Del Monte site. Cost for the
pretreatment at the Del Monte site could exceed $250,000.
• Storage, sprayfield and pump station improvements, and
construction of some treatment processes to accommodate future
growth could approach $1.0 million at the Wastewater Facility.
• American Foods has a very small impact on the overall
sprayfield site and could easily connect to the domestic system
thereby reducing their financial obligations. This option is not
presently considered viable for the large loading from the Del Monte
Plant.

An Ecology mandated Engineering Report to more accurately identify
costs and options for sprayfield and groundwater improvements is
the next course of action. The final outcome of this state mandated
study has ultimate bearing on the charges to the affected industry(s)
or the general sewer rate payzrs. We respectfully suggest that the
long term framework for identifying financial, environmental, and
contractual responsibilities begin in earnest before large capital
outlays are committed. This framework would inevitably revisit the
current subsidization arrangement between the City and the
sprayfield industries.

MEMORANDUM
November 12, 1997
To: Honorable Mayor, Members of City Council, and City Manager
From: Chris Waarvick, Wastewater Plant Superintendent
Bruce Bates, Assistant Wastewater Superintendent
Subject: Contract Amendment 3 for CH2M Hill to perform Industrial
Waste Sprayfield Engineering Report
Staff respectfully request City Council approval of the attached resolution
authorizing the City Manager to execute the attached contract amendment #3
with CH2M Hill. This contract will provide for the development of a detailed
engineering report as required by Ecology in the City's new National
Pollutant Discharge Elimination System (NPDES) permit. The detailed
engineering report, at a cost of $50,200, will include conceptual designs, order
of magnitude costs, and numerous Ecology required planning elements.
Provisions to conduct a detailed engineering report were already approved
through Contract Amendment #2 (enclosed) with CH2M Hill. However, the
scope of work has been updated to reflect City Council review of the
completed Industrial Waste Sprayfield Suitability Study (4-94) and issuance of
the City's new NPDES permit.
Enclosed for your information are two Council Information Items which
were prepared for Council concerning the Industrial Waste Sprayfield
Suitability Study and related issues (dated 4/22/94 and 5/9/95). Staff
anticipates authorizing CH2M Hill to proceed on this project upon receiving
approval of the attached amendment. There is limited time to complete
these tasks as described in the attached and highlighted excerpt from our
newly issued NPDES permit. The 1997 and preliminary 1998 budgets have
resources to accommodate the $50,200 cost of the detailed engineering report
(Project #1641-478 Fund).
This is one of the major impacts of the new NPDES permit. Two other major
areas are:
1) Capital facilities demands of the treatment facility; and
2) Pretreatment program requirements to comply with the delegated
program mandate.
An extensive report is under development for pretreatment issues and HDR
Engineering, Inc. and staff have been developing costs for treatment
demands.
