BUSINESS OF THE CITY COUNCIL
YAKIMA, WASHINGTON
AGENDA STATEMENT
Item No. 7.E.
For Meeting of: January 7, 2020
ITEM TITLE: Resolution authorizing award of RFP 11913P and execution of an
agreement with Natural Selection Farms, to provide Biosolids
Hauling and Land Application Services
SUBMITTED BY: Maria Mayhue, Senior Buyer
575-6094
SUMMARY EXPLANATION:
Treatment processes at the City of Yakima Wastewater Treatment Plant (City)generate
approximately 8,000 wet tons of biosolids per year. In compliance with the City's coverage under
the Department of Ecology General Biosolids Permit (Permit), the biosolids are treated and
verified through laboratory testing to meet all federal and state Class B biosolids standards. The
Class B designation qualifies the biosolids for beneficial use including conditional land
application. The current Permit and the City's 2018 Annual Biosolids Report to Ecology,
including laboratory testing results, are attached for reference.
The City's coverage under the Permit does not include biosolids hauling or land application, so
the City contracts for these services through the bid process. Qualified bidders must maintain
coverage and compliance with the General Biosolids Permit for these functions. Compliance
with the Permit's hauling restrictions include proper load coverage during transport and spill
containment/clean-up plans for transportation accidents. Permit restrictions for land application
include containment requirements and strict observation of agronomic land application rates,
verified through the laboratory testing of soils, to protect groundwater from nutrient infiltration.
The Permit also includes land application setback and vegetation buffer requirements for the
protection of surface waters. Complete details can be found in the attached Permit.
Yakima Wastewater Treatment Plant has completed the proposal and evaluation process for
selecting a contractor to provide Biosolids Hauling and Land Application Services. The
Evaluation Committee recommends Natural Selection Farms as the selected contractor. Please
see attached Cover Letter/ Recommendation of Award / Natural Selection Farms, Inc. General
and Site-Specific Land Application Plans.Agreement Exhibits A& B are on file in the Purchasing
Office.

referred to as "Services") according to the procedure outlined in RFP #11913P Biosolids Hauling & Land Application

5. Expansion
Contract may be further expanded by the Purchasing Buyer in writing to include any other related service(s) normally

the listed item.
Any new services accepted by the City may be added to this contract and/or substituted for discontinued services.
New services shall meet or exceed all proposal specifications of original award.
6. Price Adjustment for Change in Law
NSF may, subject to agreement of the parties, increase the minimum service fee by one hundred percent (100%) of
NSF's reasonable actual increased costs of performing its obligations under this Contract due to a change in law. For
purposes of this section, a "change in law" includes new laws, regulations, ordinances of general application and
modifications of them; new decisions of tribunals, either judicial or administrative, and any modifications of them, or the
imposition of any material conditions on the renewal of any permit, license or approval which makes the transportation,
storage, land application or other management of biosolids more burdensome financially than under the requirements
in effect at the Effective Date; a"change in law" shall include, without limitation, a determination that performance by
NSF of the terms of this Contract requires that NSF pay prevailing wage rates, as may be required by law; it being a
basis of the price terms in this Contract that NSF is and shall not be required to pay prevailing wage rates.Whether or
not a change in law material to this Contract has occurred shall be determined by agreement of the parties, in writing.
Such increase in service fees may occur only for reasonable costs that are actually incurred and shall not be allowed
for any cost increases that are in any way attributable to activities caused by NSF or its subcontractors, employees, or
agents, or are otherwise within NSF's control.
7. Adjustment of Fees
The non-fuel-related service fee for this Contract shall be adjusted annually on the yearly anniversary date of this
Contract, beginning one year after the date of execution. Said adjustment shall be 1°/0 plus an additional factor dictated
by, and directly proportional to, the percentage change in the Consumer Price Index for All Urban Consumers (CPI-U)
for Size Class B/C (Series ID: CUURN000SAO,CUUSN000SA0) over the same period of time.
Calculation to be used for CPI adjustment,in addition to 1`)/0 annual adjustment:CPI for the most recent month
available as of the anniversary date of the contract, less CPI for the same month of the previous year*, equals
index point change. Index point change, divided by previous year's CPI, with result multiplied by 100, equals
percent change, *Note:the first yearly index point change calculation will reference the CPI for the most recent
month available as of the anniversary date of the contract, less CPI from the RFP due date of August 30,
2019.
The fuel-related service fee for this Contract shall be adjusted quarterly. This fuel-related fee will be adjusted on
January 1, April 1, July 1 and October 1 using the most recent values available as of the date of the adjustment. The
fuel portion rate adjustment shall be made for#2 diesel fuel (PPI Series ID: wpu057303).
Calculation to be used: PPI for the most recent month available as of the date of the adjustment ("current
period"), less PPI for the month three months prior to the current period, equals index point change. Index
point change, divided by prior PPI, with result multiplied by 100, equals percent change, *Note: the first
quarterly index point change calculation will reference the PP/ closest to the RFP due date of August 30,
2019.
Example: As of October 1,the most recent PPI available is for August, which is 207.6. The month three months prior
to August is May at 235.5. Calculation: 207.6—235.5= -27.9÷ 235.5= -0.119 X 100= -11.9.
For the purpose of confirming the accuracy of any proposed fee adjustment, NSF shall submit proposed fee
adjustments, including supporting CPI and PPI documentation, for the City's review and consent, which the City shall
11913P Agreement-Biosolids Hauling& Land Application Services-WWTP Page 2 of 9
7
not unreasonably withhold. Payment of an erroneous invoice does not constitute acceptance of the erroneous pricing,
and the City would seek reimbursement of the overpayment or would withhold such overpayment from future invoices.

General Permit for McGe lds Management Page 1
1. Overview of the General Permit for Biosolids Management
L1 Introduction
The biosolids program in the State of Washington is based on Chapter 173-308 WAC Biosolids
Management. The state program, including this General Permit for Biosolids Management(permit), is
intended to comply with all applicable federal rules adopted pursuant to the federal Clean Water Act as
it existed on February 4, 1987, and Chapter 90.48 RCW Water Pollution Control. Authority for
administering a state biosolids management program is granted to Ecology in Chapter 70.95J RCW,
Municipal Sewage Sludge-Biosolids.
The State program regulates biosolids (including septage) applied to the land for beneficial uses,
biosolids being stored, sewage sludge disposed in a municipal solids waste landfill and biosolids
transferred from one facility to another.
Although the state program does not regulate surface disposal or incineration,the transfer of biosolids
from a wastewater treatment plant to an incineration facility or surface disposal site is an activity
covered under this permit.
1.2 Use of the terms "Sewage Sludge", "Biosolids", and"Septage"
Sewage sludge is the solids, semisolids,or liquid residue generated during the treatment of domestic
sewage in a treatment works. Biosolids are produced by treating sewage sludge to meet certain quality
standards that allow it to be beneficially used. Septage is a class of biosolids that comes from septic
tanks and similar systems receiving domestic wastes.
In this permit:
Sections 8, 9, and 10 apply only to biosolids or "septage managed as biosolids originating from sewage
sludge".
Section 6 applies only to sewage sludge being disposed in a municipal waste landfill.
Section 11 applies only to septage being applied to the land.
All other section apply to biosolids,septage and sewage sludge unless the context requires otherwise.
1.3 Geographical Area Covered
This permit applies to facilities and biosolids management activities that occur on lands under the
jurisdiction of the State of Washington.
Any treatment works located outside of the jurisdiction of the State and exporting biosolids into the
State must do so in accordance with WAC 173-308-130.
1.4 Persons Required to Apply for Coverage under this Permit
Unless you are obtaining an individual permit in accordance with WAC 173-308-310,you must apply for
coverage under this permit if you own or operate any of the following facilities:
19
General Permit for McGe lds Management Page 2
• Facilities designated by Ecology as a treatment works treating domestic sewage in accordance
with WAC 173-308-310(1)(b).
• Publicly owned treatment works.
• Privately owned treatment works treating only domestic sewage.
• Industrial facilities that treat domestic sewage separately from the industrial waste stream and
generate biosolids regulated by Chapter 173-308 WAC.
• Beneficial use facilities.
• Composting facilities that compost non-exceptional quality biosolids that do not have an
adequate permit issued by the local health jurisdiction as determined by Ecology.
• Facilities that mix non-exceptional quality biosolids with other material, including other
biosolids.
• Septage Management facilities.
1.5 Activities Subject to Coverage under this Permit
Coverage under this permit is based on activities related to the use or disposal of biosolids. These
activities include, but are not limited to,the following:
• Applying bulk biosolids to the land, including, but not limited to, agricultural lands, forest lands,
public contact sites,and land reclamation sites.
• Applying septage to the land.
• Disposing sewage sludge in municipal solid waste landfills.
• Selling or giving away biosolids in bags or other containers.
• Storing biosolids.
• Transferring biosolids from one facility to another.
• Composting non-exceptional quality biosolids.
1.6 Local Health Jurisdiction Involvement.
Ecology may delegate authority to a Local Health Jurisdiction (LHJ) to implement and assist in the
administration of Chapter 173-308 WAC and this permit. Delegation is accomplished through an
instrument of mutual consent(for example,a Memorandum of Agreement) that is acceptable to both
Ecology and the LHJ. When applying for coverage under this permit, contact Ecology to find out the
status of delegation agreements in the areas where you treat, store, transfer, or apply biosolids to the
land.
20
General Permit for McGe lds Management Page 3
1.'7 Role of EPA
EPA has a responsibility for implementing a national biosolids management program. EPA Region 10 and
Ecology work cooperatively on program implementation. EPA provides periodic technical assistance to
the state; in return the state provides certain information on request to EPA regarding biosolids
management in Washington.
All applicable facilities in the state must meet requirements set forth by both the state and the federal
programs; satisfaction of the state program requirements does not necessarily satisfy federal
obligations.
2e Applying For Coverage under this Permit
2.1 When to Apply
All existing facilities required to be covered under this permit must submit a complete application within
90 days of the effective date of this permit unless you have received approval from your regional
biosolids coordinator to submit your application within 180 days of the effective date in accordance with
WAC 173-308-310(4)(a).
All new facilities must submit a complete application (subsection 2.4) at least 180 days in advance of
engaging in biosolids management activities.
2.2 Complying With the State Environmental Policy Act
The act of applying for coverage under this permit triggers a requirement for review under the State
Environmental Policy Act(SEPA) Chapter 197-11 WAC.
It may be possible to use previous SEPA documents to comply with the SEPA requirements. For this to
be the case,the SEPA lead agency must be able to conclude that possible site specific environmental
impacts of applying biosolids have been adequately considered in existing SEPA documents. As part of
approving coverage under this permit, you must provide written documentation from the SEPA Lead
Official showing that the SEPA requirements have been met.

for treatment or management if the following conditions are met:
• Nothing in the permit for either the sending or the receiving facility prohibits the transfer of
biosolids.
• Both the sending and the receiving facility exchange adequate information needed to comply
with this permit and Chapter 173-308 WAC. This may include, but is not limited to, information
on biosolids quality and the permit status of each facility.
• Approval from Ecology.
8. Requirements for Analyzing Eiosolids and Monitoring Processes
This section contains the minimum requirements for biosolids analysis and process monitoring that are
applicable when you prepare biosolids for land application or sale/give away.
You must submit a biosolids sampling plan that addresses how you intend to meet the requirements in
this section. As part of the approval process, Ecology may require biosolids analysis and/or process
monitoring beyond the minimum requirements in this section.
31
General Permit for B oselids Management Page 14
8.1 Representative Sampling
Samples collected for analysis and monitoring locations must be representative of the biosolids or the
treatment process used to prepare the biosolids.
8.2 Frequency of Biosolids Analysis
At a minimum,you must analyze your biosolids at the frequency listed in Table 1. Ecology may require
additional sampling and analysis. The frequency of biosolids analysis is based on the dry weight tonnage
of biosolids applied to the land or prepared for sale/give away per 365-day period. For facilities that
compost or mix Class B quality biosolids with other materials, the frequency of analysis is based on the
dry weight tonnage of the total amount of material, not just the biosolids.
Table 1 applies to the pollutants in WAC 173-308-160 the pathogen density requirements in WAC 173-
308-170,the vector attraction reduction standards in WAC 173-308-180,and the nitrogen
concentrations and percent solids needed to support agronomic rate determinations. It does not apply
to process monitoring, which is described in Subsection 8.3.
Table 1 Minimum Frequency of Biosolids Analysis (adapted from WAC 173-308-150)
Metric tens per Year Frequency*
<1 - 290 (<1- 320 U.S. tons) once per year (1X per year)
290- 1,500(320- 1,653 U.S. tons) once per quarter(4X per year)
1,500- 15,000 (1,653- 16,535 U.S. tons) once per 60 days (6X per year)
>15,000(>16,535 U.S. tons) once per month (12X per year)
* after 2 years of analyzing at this frequency,analysis for the pollutant concentrations may be
reduced, but it must not be less than once per year
8.3 Frequency of Process Monitoring
Monitoring of the processes used to prepare biosolids that are land applied or sold/given away must be
conducted at a frequency and duration that will ensure that the process meets the applicable
requirements. This applies to the pathogen reduction processes in WAC 173-308-170 and the vector
attraction reduction processes in WAC 173-308-180. As an example,Table 2 provides the minimum
expectations for monitoring temperatures for a specific composting process.

8A Point of Compliance
The point of compliance for a sample is the date on which the sample is taken, not the date on which
results are subsequently reported.
You may distribute biosolids based on the most recent analytical results. However, if subsequent results
show that you distributed biosolids that failed to meet the appropriate standards, you will be in
violation of this permit.
8.5 Requirement for Analysis by an Accredited Laboratory
An accredited laboratory is a laboratory accredited under Chapter 173-50 WAC,Accreditation of
Environmental Laboratories, for a specific analyte using a specific analytical method.
All required biosolids analyses must be performed by a laboratory that is accredited by Ecology for the
respective method used if an accreditation protocol for the method exists. Accreditation must be under
the "Solids and Chemical Materials" matrix, unless otherwise approved
8.6 Analytical Methods

AAR = N _ 0.0026
Where:
AAR=annual application rate in gallons per acre per 365-day period
N=amount of nitrogen in pounds per acre per 365-day period needed by the crop or vegetation grown on
the land(subtract any nitrogen supplied by other sources—for example, commercial fertilizers or manures)
Equation 2—Spreader Drive Length for Septage
Drive length (in feet) = gallons _spread width (in feet) x 43,560 _AAR
Where:
AAR=annual application rate in gallons per acre per 365-day period determined by Equation 1
40
General Permit for B oselids Management Page 23
11.4 Pollutants
The septage application rate formula in Equation 1 was developed by EPA. EPA included acceptable
pollutant loading from septage into the formula.Testing for pollutants in WAC 173-308-160 is not
required for septage applied to land. Ecology may require additional or more stringent testing
requirements developed as a condition of final coverage under this permit.

Preface
This document is written in accordance with WAC 173-308, Appendix 4, Minimum
Content for a General Land Application Plan. The purpose of this plan is to:
• Provide broad information about the geographical area where Natural
Selection Farm (NSF) land applies biosolids;
• Set forth general site selection criteria where new fields can be identified
and added to NSF permit coverage;
• Describe general management guidelines for areas receiving biosolids;
• Public Notice procedures for adding new fields to NSF's permit coverage.
1) Geographical Area
The following lists the names of all counties and water resource inventory areas
(WRIA) where biosolids may be applied by NSF under their permit coverage:
County Water Resource Inventory Area(s) WRIA
Benton Rock Glade, Lower Yakima 31,37
Kittitas Upper Yakima, Alkaki/Squilchuck 39, 40
Klickitat Klickitat, Rock Glade 30, 31
Yakima = Lower Yakima, Naches, Upper 37, 38, 39
Yakima
2) Site Selection Criteria
NSF desires to maximize the beneficial use of the biosolids products we manage.
To meet this goal, potential land application sites are selected with a preference
for productive soils and for soils that can be substantially improved with biosolids
application. Biosolids will be applied to sites managed for:
• Commercial agriculture;
• Pasture and rangeland;
• Land reclamation sites.
Sites are evaluated on a case by case basis for suitability based on a number of
factors including:
• Topography/slopes;
• Soils;
• Depth to groundwater;
• Precipitation;
• Zoning;
• Neighboring land use;
Natural Selection Farms, Inc. 12.22015 General Land Application Plan Page 2 of 6
70
• Access and storage.
Site/Soil conditions not suitable for land application of biosolids:
• Anaerobic soil conditions (presence of gleyed soils or mottling);
• Hardpans or lithic layers within 12 inches of the surface;
• Slopes exceeding 25%;
• Sites immediately adjacent to residential areas.
Sites proposed for biosolids application that have a seasonal groundwater depth of
less than 3' below the surface will be managed by a Ground Water Protection Plan
detailed in the Operations/Site Specific Land Application Plan.
The Washington State Department of Ecology Publication #93-80, Biosolids
Management Guidelines for Washington State as revised in July 2000, and any
subsequent revisions, shall be used a guide for site selection. Additional site
selection and design assistance is provided by University of Washington, Washington
State University biosolids researchers, extension agents, or professional soil scientists.
3) Site Management
NSF will manage all sites in accordance with WAC 173-308, the Operations/Site
Specific Land Application Plan, and any conditions noted in the letter providing
Final Coverage under the General Permit for Biosolids Management.
4) Advance Notice to the Permitting Authority for New or Expanded Land
Application Sites
The following outlines the procedure for proposing a new land application site or
expansion of an existing land application site under this General Land
Application Plan:
• Advance notice to the Department of Ecology that includes the
information contained in WAC 173-308-90003, Appendix 3: Items 1, 2, 7, 8,
9, 12, and 13. This information may be submitted electronically or by hard
copy to the regional Biosolids Coordinator.
• Review of the site by Ecology;
• Concurrence of both NSF and Ecology about land Application Site details
to include, but not be limited to: 1) field size, 2) buffers, 3) truck access, 4)
biosolids on-site storage, 5) any application restrictions or requirements.

5) Advance Public Notice for New or Expanded Land Application Sites
When a new land Application Site or expansion of an existing land Application
Site is proposed, NSF will complete the requirements listed in Section 4 (above),
Advance Notice to the Permitting Authority for New or Expanded Land
Application Sites. Once Ecology sends written acknowledgement that they
have received adequate drafts of WAC 173-308-90003, Appendix 3: Items 1, 2,
7, 8, 9, 12, and 13, NSF will post the site in accordance with WAC 173-308-
310(13)(g), (h),(i),(j), and (k).
After the proposed site has been posted for a minimum of 30 days, Ecology shall
evaluate any public comments received and provide NSF a permitting decision
in writing (approval or disapproval of the site).
The process of documenting expansion shall include the following general
process:
1) NSF will provide Ecology with maps meeting the requirements listed in Appendix
3, item #9;
2) Ecology will evaluate and acknowledge receipt of the map(s);
3) Ecology will inspect the site;
4) NSF will post the site with appropriate public notice signs—see attached;
5) NSF will contact, in writing, all appropriate persons on their Interested Parties list
and provide documentation of such contact to Ecology;
6) Ecology will evaluate all comments received during the official comment period;
7) Ecology will make a permitting decision subsequent to comment evaluation;
8) Ecology will notify NSF of the permitting decision by email;
9) NSF will maintain a Permitted Field List and will add the new area to the list and
send that updated list to Ecology within 14 calendar days;
10)The most recently dated Permitted Field List will document the permitted land
base.

1.0 Introduction
Natural Selection Farms (NSF) handles Biosolids suitable for land application and has
regulatory obligations under WAC 173-308, Biosolids Management. This document
satisfies the requirements for a Site Specific Land Application Plan and sets forth the
procedures for land application in partial fulfillment of those requirements. This is a
"living" document and will be amended and updated as new procedures are added
or existing ones are changed. The Department of Ecology has permitting and oversight
authority for the implementation of this plan.
1.1 The Goals of this plan include the following:
• Establish the procedures governing a biosolids land application program for NSF
sufficient to meet or exceed Beneficial Use of Biosolids as defined in WAC 173-308-
080;
• Ensure consistent, uniform, and orderly land application of biosolids at agronomic
rates;
• Improve soil characteristics at land application sites.
1.2 The following objectives are set forth to structure the procedures for land
application in order to achieve the plan goals:
• Identify and map specific biosolids Application Sites that are scientifically defensible
and have limited public controversy;
• Provide the amount of plant available nitrogen (PAN) necessary for the optimum
growth of a targeted vegetation type through soil sampling and agronomic rate
calculation procedures;
• Document allowable activities regarding the storage, handling, and application
methods for Biosolids;
• Define biosolids practices that enhance the intended crop type while limiting
noxious weeds.
2.0 Definitions
This section should contain all terms requiring a definition or explanation in order to
clarify meanings and eliminate ambiguity.
Agronomic Rate: The biosolids application rate that provides the amount of nitrogen
necessary for the optimum growth of targeted vegetation, and that will not result in the
Natural Selection Farms, Inc. 12.2.2015 Operations/Site Specific Land Application Plan Page 3 of 12
76
violation of applicable standards or requirements for the protection of ground or
surface water as established under chapter 90.48 RCW and related rules including
chapters 173-200 and 173-201 A WAC.
Application Sites: Those areas specifically evaluated, mapped, and approved for land
application of biosolids at agronomic rates under authority of Chapter 173-308 WAC.
Biosolids: Municipal sewage sludge that is a primarily organic, semisolid product
resulting from the wastewater treatment process that can be beneficially recycled and
meets all applicable requirements in Chapter 173-308 WAC.
Dewatered Biosolids: Biosolids that have had water removed sufficiently to allow it to
be land applied as typical biosolids cake, i.e., suitable for land application. These
biosolids are typically in excess of 10% solids.
Drying Bed Biosolids: Biosolids that have air-dried in drying beds and are typically in
excess of 80% solids
Liquid Biosolids: Biosolids that shall be land applied with equipment suitable for evenly
land applying liquid at agronomic rates
Ecology: Washington State Department of Ecology
Permittee: Natural Selection Farms, Inc (NSF); the entity that is covered under the
General Permit of Biosolids management for which this plan is written
3.0 Mapping Requirements
The land Application Sites permitted under this plan shall be discrete areas with specific,
identifiable boundaries and some type of a unique name or identifier. Biosolids shall
only be applied to mapped and approved Application Sites. The name and/or
number of these sites shall be shown on the maps and used for referencing individual
areas for agronomic rate calculations or other biosolids management requests. Note,
not all past permitted areas have not been mapped to these standards, Application
Site maps will be updated over time as agronomic requests are made to Ecology.
3.1 Map Contents
Geographical Information System (GIS) has been used to digitally map the extent of
sites permitted for biosolids application by NSF. To develop this data base we have
made every effort to use the most accurate data available to the consumer/general
public. However, even in the most standard maps, an inherent degree of inaccuracy
exists, and prevents our map layers from overlying each other perfectly. Due to this
inaccuracy, NSF adheres to buffer distances identified in this Operations/Site Specific
Land Application Plan and uses the buffers identified on the maps for reference
purposes only.
Natural Selection Farms, Inc. 12.2.2015 Operations/Site Specific Land Application Plan Page 4 of 12
77
The GIS database will be updated on an ongoing basis. Reasons for this include:
• Map updates from the various data sources
• Refinement of fields and buffer layers as the map quality improves
• Technology improvements
• Expansion of permitted areas
All maps include as a minimum: a title, a date, a north arrow, a legend that defines all
map symbols, and a map scale. Maps shall specifically identify the Township, Range,
and Section of all properties for which biosolids are to be applied.
As the maps will be stored in an electronic data base, they will be of an appropriate
scale to show the detail necessary for evaluation of the proposed application areas.
Data maintained in the map database includes individual Application Site boundaries,
tillable acres, buffers, contour lines, perennial and intermittent streams,wetlands, all
known roads, property boundaries, adjacent properties and their zoning classification,
wells and well circles, NRCS Soil survey information including soil types and their
descriptions, presence and extent of any threatened or endangered species or related
critical habitat, and the location of any critical areas on site as required to be identified
under chapter 36.70A RCW in the county's growth management plan
4.0 Soil
NRCS Soil reports are examined for each of the land application areas. Principle soils
groups are available as a map layer.
4.1 Soil Sampling Procedures
Prior to determination of an application rate, composite samples shall be collected
independently from the top three feet of soil. The samples shall be taken separately
from each foot of soil 0-12", 12-24", and 24-36" where possible, within all Application
Sites on which biosolids are to be applied. The individual samples are typically soil cores
10-12" in length, taken from the indicated depths. The individual samples should be
located in an unbiased fashion and evenly distributed in order that the composite
sample is representative of the soil across the entire Application Site. For hop yard
sampling protocol, see 7.3 Agronomic Rate Calculations for Hop Yards.
Separate composite samples shall be collected for each Application Site each time an
agronomic rate is calculated. These samples shall be analyzed for ammonium (NH4) or
ammonia (NH3), nitrate (NO3), total nitrogen (or TKN) and percent organic matter unless
other analytical results are requested by Ecology.
For any site that has not previously received biosolids, concentrations of the Pollutants
(WAC 173-308-160, Table 1) shall be determined for the top foot (0-12") of soil prior to
any biosolids land application under this plan.
Natural Selection Farms, Inc. 12.2.2015 Operations/Site Specific Land Application Plan Page 6 of 12
78
5.0 Buffers
Biosolids applied to Application Sites identified in this Operations/Site Specific Land Plan
shall maintain the minimum buffer widths shown below. Buffer distances may be
adjusted based on site-specific considerations or monitoring data. These buffers shall
be identified on Application Site maps. Minimum buffer distances are based on the
Biosolids Management Guidelines for Washington State; Publication #93-80, revised July
2000.
Domestic, Irrigation, or Sampling Well Buffers: 100'
Property Buffers (Roads, Dwellings, Fence Lines): 0-50'—Dependent upon
circumstances.
Where there are no sensitive adjoining property uses buffer may be reduced to near
zero. NSF standard application minimums are listed below as follows:
• Property Line: 5-50'
• Occupied Home: 100' exceptions permitted with home owner approval
• Major Arterial or highway: 25'
• Public/Minor Road: 5-50'
Federal and State rules require minimum buffers of 33 feet to all waters of the U.S. for
Class B biosolids. Prior to each application, NSF determines the appropriate buffer by
evaluating the site circumstances in reference to the Biosolids Management Guidelines
for Washington State in the table below. Wetlands are managed as surface water.

6.0 Application Site Approval
Biosolids shall be applied only to areas identified on maps attached with, or as an
addendum to this Site Specific Land Application Plan. All sites authorized for biosolids
land application shall be approved by Ecology in advance of land applying biosolids.
If Application Sites are to be added to the area managed under this Site Specific Land
Application Plan, they must meet the requirements set forth in the NSF General Land
Application Plan, and Sections 3 and 5 above before being reviewed for approval.
Ecology reserves the right to exercise professional judgment when evaluating proposed
Application Site's suitability to meet rule requirements as well as the goals and
objectives set forth in this plan.
7.0 Application Rates
Agronomic application rates for biosolids shall be calculated and approved by Ecology
prior to biosolids land application unless Ecology agrees to other conditions on a site-
specific basis. A revised agronomic rate will be calculated each time biosolids are to
be land applied except as noted under section 7.2 for rangeland applications.
7.1 Basis for Biosolids Application Rates
Agronomic rates shall be separately calculated for different crop species grown on a
given Application Site.
Application rates for biosolids shall be based on the following: the soil analysis, pounds
per acre nitrogen uptake (if this is yield-based, data should be provided) or crop
requirement, nitrogen content of the biosolids, current data on soil nitrogen status, soil
type, total soil organic matter, an estimated biosolids mineralization rate, and the
professional judgment of Ecology.
Cooperative Extension Services, University fertilizer guidelines, or an agronomist / soil
scientist shall be the basis of recommendations for plant available nitrogen (PAN)
additions. The information upon which the recommendation is based shall be provided
to Ecology prior to approving a biosolids application rate.
7.2 Range Land Agronomic Rate Calculations
For biosolids applications to rangeland, vegetative production (yield, in tons per acre)
will need to be estimated. The estimate of production shall be used in calculating plant
uptake of nitrogen. An acceptable method for calculating annual plant uptake of
nitrogen is the following:
Equation 1: Crude Protein / 6.25 = % N of Dry Matter
Equation 2: (% N of Dry Matter)X (Est. Dry Matter Annual Production) = Annual Nitrogen Uptake
Natural Selection Farms, Inc. 12.2.2015 Operations/Site Specific Land Application Plan Page 7 of 12
80
NOTE: To utilize Equations 1 & 2, field sampling of vegetation from primary forage
species shall be conducted. These samples shall be analyzed for crude protein in order
to determine the input value for Equation 1. Estimates of forage species dry matter
annual production shall be determined from authoritative sources such as University
Extension, rangeland specialists, or other science-based data where the source
information can be verified.
The application rate initially calculated for rangeland shall remain in effect until Ecology
determines that a revision is necessary. Revisions may be based upon soil nitrogen
testing or other factors that would indicate different rates of application are
appropriate. Multiple year applications may be approved on a site-specific basis.
7.3 Agronomic Rate Calculations for Hop Yards
Information gained through the mineralization studies and the utilization of biosolids
from previous years of applications and the restructuring of hop plantings has led to this
method of agronomic rate calculations for biosolids applications to hop yards.
1 . Pre-winter soil samples shall be taken prior to spring biosolids application when
possible. This sampling will likely occur during the October through November
sampling window, to determine plant available nitrogen (PAN) within the rooting
zone of the hops. Hop yards that are being modified, replanted or in a condition
that makes fall sampling unsuitable, will be sampled as early in the spring as
weather permits. As a BUF, NSF actively solicits growers to change to an organic
method of crop fertilization and soil enhancement. If we are given approval to
supply biosolids to a field after the designated sampling window, it will be
necessary to sample early spring to determine an accurate application rate for
the fields.
2. Sampling will be conducted in the top 3 feet of soil in 1 foot increments. Samples
will be taken within the hop row, not to be more than l ' to either side, ie directly
on top of the hill. This data for all hop yards where biosolids are applied shall be
provided to Ecology.
3. A requirement for 100 lbs N/ac residual in the top 2 feet of soil after a growing
season has been identified as acceptable. Biosolids may be applied at such
rates that plant available nitrogen in the year of application is 250 lbs/acre; this is
to include residual soil mineral nitrogen and estimated mineralized nitrogen from
biosolids.
4. For broadcast applications, the majority of the applied biosolids shall be
windrowed, scraped, or otherwise moved away from the middle of the row and
deposited next to the hop row for better utilization of the nitrogen by the hops.
This means that the overall biosolids application rate will be reduced as it will only
be covering about a 5-6 foot band near the hop row and not the entire 14 foot
spacing per row. Therefore, the agronomic rate determined in #2 above, shall
be multiplied by a factor of 0.75 to account for the non-farmed "middles".
Natural Selection Farms, Inc. 12.2.2015 Operations/Site Specific Land Application Plan Page 8 of 12
81
5. Due to variation in biosolids mineralization, fields may receive up to an additional
100 lbs N/ac through the drip irrigation system. Leaf petiole sampling during June
will regulate how much of the scheduled drip applied nitrogen is needed.
Growers will follow historical petiole nitrate nitrogen values they have established
for each variety, and will cease drip applied nitrogen if petiole values exceed
the normal nitrate nitrogen range for a particular variety. Baby hops with a
limited root system will be an exception as drip applied nitrogen may need to be
continued, even with high petiole nitrate nitrogen levels. The baby hop yards
shall be specifically identified to Ecology prior to biosolids land application.
6. A cover crop will be seeded in all hop yards that receive biosolids. This crop shall
be mowed at least once per year during the growing season, discharging the
cut material towards the hops to be later incorporated next the hop row.
Alternatively, this cover crop may be cut and removed. Planting of the cover
crop will be as early as possible to maximize plant growth and nitrogen removal
from areas outside the reach of hop roots. Late fall and/or winter biosolids
applications may result in the cover crop being spring planted. If soil samples
demonstrate residual nitrate has not accumulated in the middles, this
requirement may be waived.
7. Soil sampling between rows shall be conducted on all yards where biosolids will
be applied. These samples shall be taken no closer than 6 feet from the row.
This should provide a two foot band in the middle of rows from which to sample.
These samples shall be a composite of at least 5 separate locations in each yard.
One composite shall be taken at each 1 foot of soil. Soil shall be sampled to 3
feet. Sampling between the rows will be conducted upon the request of the
Biosolids Coordinator at Ecology's Central Regional Office.
7.4 Agronomic Rate Approvals
Ecology shall have 14 calendar days for review of information regarding agronomic
rate recommendations. The 14 day review period shall begin after all necessary
information to calculate the recommendation is received in writing by the designated
Ecology staff member. If Ecology does not respond within 14 days of receiving all
necessary information upon which a recommendation is based, it shall be considered
approved.
8.0 Application Methods
Land application of biosolids shall be conducted with equipment suitable for the
purpose and the material being land applied. This means that land application
methods shall produce even and consistent spread patterns in accordance with the
calculated agronomic rate(s).
Natural Selection Farms, Inc. 12.2.2015 Operations/Site Specific Land Application Plan Page 9 of 12
82
8.1 Conditions of Applications
Biosolids will be applied when weather and site conditions allow for proper application
and management. Unless approved by Ecology, biosolids will not be applied if the soil
is saturated or flooded, frozen, covered with snow, or other conditions that could result
in soil damage or off-site movement of biosolids.
8.2 Incorporation of Biosolids
Biosolids that does not meet Vector Attraction Reduction (see WAC 173-308-180) shall
be incorporated into the soil within 6 hours after land application. Injection of liquid
biosolids meets VAR incorporation requirements. Biosolids that do not meet vector
attraction reduction shall not be surface applied on established grass hay fields.
8.3 Application of Liquid Biosolids
Liquid biosolids shall be applied by equipment appropriate for even distribution of liquid
material for the specific land application.
Liquid biosolids shall not be applied in such a manner that it results in runoff. This may
have the practical effect of limiting application volumes on slopes, relative to volumes
applied on level ground. Material shall not be applied in excess of the calculated
annual agronomic rates. In addition, it shall be insured that liquid material does not
migrate from the location applied. If agronomic rates allow for application volumes
that result in runoff, the biosolids may have to be applied in separate applications to
prevent such runoff. Multiple applications may be allowed in order to reach the
agronomic rate, although time may be required for infiltration to prevent runoff or
damage to soil structure from running equipment on wet soil.
9.0 Biosolids Storage
Biosolids products from different generators shall be stored separately. Where biosolids
from different generators are stored at the same location, each storage pile shall be
clearly marked with signs indicating the source of the biosolids. These signs need to
remain legible during the entire period of storage. It's typically the case that signs
weather to extent that they become unreadable. It is NSF's responsibility to maintain
these signs. Ecology shall be given authority to rescind storage or application
approvals if storage sites and / or signage are not properly maintained.
Prior to storing biosolids on an application site, the agronomic rates for an application
site shall be calculated and approved, unless Ecology has specifically granted storage
approval in advance of an approved agronomic rate.
Natural Selection Farms, Inc. 12.2.2015 Operations/Site Specific Land Application Plan Page 10 of 12
83
10.0 Landowner Agreements
At the time their property is submitted for application or storage site approval, Ecology
shall be provided with signed agreements that acknowledge the applicability and
requirements of Chapter 173-308 WAC from landowners (as distinguished from a lessee,
farmer, or others entitled to use the land).
11.0 Pollutant Concentrations
To the best of NSF's knowledge, biosolids with pollutants in excess of the values in WAC
173-308-160 Table 3 have not been applied to Application Sites covered by this plan.
12.0 Ground Water Protection Plan
If any active application site has groundwater within 3 feet of the surface during any
part of the year, NSF shall have a Ground Water Protection Plan. The details of the plan
shall be drawn up to meet the specific area and can include simple measures like
restricting application during periods when the water table is high.
13.0 Crops, Use, and Production
All relevant crop information such as crop type, standard production information,
generally intended use, distribution information, and farming practices shall be
submitted with each request for an agronomic rate recommendation. A note
regarding distribution and utilization: NSF, operating as a BUF, is not always privileged to
know where the crop will be marketed or utilized.
14.0 Haul Routes
Biosolids delivery trucks shall follow designated haul routes as shown on the Spill
Prevention and Response Plan. It's recognized that due to a variety of weather and
road related conditions that routes may be subject to change. However, when road
weight restrictions are in place, truck routes shall be coordinated with county
departments that regulate traffic on county roads.
